mudler's LocalAI [bot]andEttore Di Giacinto	0aaff91ebd	feat(ui): unify model and backend lifecycle (#11548) ... * feat(ui): add installed model lifecycle Models now owns catalog exploration and installed runtime controls under one canonical route. URL-owned state keeps lifecycle context recoverable through links and browser history. Assisted-by: Codex:gpt-5 Playwright * feat(ui): add installed backend lifecycle Backends split discovery from backend-binary management. The canonical page now keeps both lifecycle views under one URL-backed shell while it preserves target-node placement. Assisted-by: Codex:gpt-5 Playwright * fix(ui): repair lifecycle state updates Installed models lost distributed refreshes and kept a deleted selection. Backend searches also stopped tracking URL changes, while batch upgrades stopped after their first error. Preserve background refreshes and finish each requested batch action. Drive catalog results from URL-backed state without losing full metadata. Assisted-by: Codex:gpt-5 [Playwright] * feat(ui): make resource pages canonical Replace Host navigation with canonical Models and Backends lifecycle routes, preserve legacy management URLs, and surface shared host capacity on the Operate overview. Assisted-by: Codex:gpt-5 [Playwright] * feat(ui): complete canonical resource lifecycle Finish the responsive list-to-detail behavior, remove the retired Host implementation, and keep Explore focused on discovery while Installed owns destructive actions. Update regression coverage, localization, documentation, and development binding for the canonical resource pages. Assisted-by: Codex:gpt-5 [Playwright] * docs(ui): record the UI design context Record the approved users, brand character, and design principles so future interface work uses the same product direction.

mudler's LocalAI [bot]andEttore Di Giacinto	6fb9ab38aa	feat(gallery): add vllm.cpp text-generation models (#11511) ... Adds eight curated vllm-cpp entries to the model gallery. Until now the backend had gallery coverage only for MiniMax-H3 video, so serving text on it meant hand-writing engine_args. The flagship tier is what vllm.cpp gates its correctness and speed claims on: Qwen3.6-27B and Qwen3.6-35B-A3B in NVFP4, each with a speculative sibling (MTP on both, DFlash on the 27B). Qwen3-Coder-30B-A3B covers agentic tool use, and Qwen3-4B / Qwen3-0.6B in bf16 are the entries that run where NVFP4 cannot, CPU included. Three details are load-bearing rather than incidental: - The 27B entries pin revision 890bdef7. That repository was later re-quantized in place from NVFP4 to FP8 W8A8 under the same name, so an unpinned entry resolves to different weights and reports nothing. - Qwen3-Coder names tool_parser: qwen3_coder explicitly. Its dialect is byte-identical on the wire to step3p5's, so chat-template sniffing cannot separate them and auto-detection picks wrong. - enable_prefix_caching is deliberately left unset everywhere. It defaults on for dense models and off for the GDN hybrids, and that per-model default is the right answer. num_blocks is sized per model from its real KV footprint rather than copied between entries, which ranges from 20 KiB/token on the 35B to 144 KiB/token on the 4B. Docs: adds features/vllm-cpp.md covering installation, the model table, the pinning rationale and how to choose between the speculative variants, and cross-links it from the existing engine_args reference. It also records that the CUDA images are built for Blackwell only, which is narrower than vllm.cpp's own ten-architecture release and makes an otherwise cryptic "no kernel image is available" failure legible. Verified: gallery suite green; all eight decode and validate as a ModelConfig. qwen3-0.6b-vllm-cpp confirmed end to end on a real cluster, chat plus engine-parsed tool_calls. The NVFP4 entries are not yet runtime-verified: no available node has kernels for them.

3 people	88edd7fc7f	fix(distributed): run cold model loads as durable jobs instead of holding the advisory lock (#11514) ... * fix(advisorylock): set statement_timeout alongside lock_timeout WithLockCtx already overrides a deployment-wide lock_timeout on its dedicated connection so a blocking pg_advisory_lock() waits its turn instead of failing with 55P03. statement_timeout aborts that exact same statement independently, with SQLSTATE 57014, and was not overridden. Production roles commonly carry statement_timeout=60s. Any guarded section longer than that (a cold model load stages for tens of minutes) therefore killed every concurrent waiter: advisorylock: acquiring lock 9003261067483446873: ERROR: canceling statement due to statement timeout (SQLSTATE 57014) Derive it from the same context budget as lock_timeout, with a matching RESET so the pooled connection is returned clean. Assisted-by: Claude Opus 5 [claude-code] * feat(distributed): add ModelLoadJob, the durable cold-load record A cold load in distributed mode is a long-running background job, but it was modelled as a synchronous side effect of an inference request: the whole of it (backend install, multi-GB staging, checkpoint load) ran inside the per-model advisory lock. Loading a 35.7 GB GGUF held that lock for ~20 minutes, so every concurrent request for the same model blocked on pg_advisory_lock and died at the role's 60s statement_timeout. Introduce the row that lets the lock shrink to a decision. Exactly one ModelLoadJob may be active per tracking key; that uniqueness — not the lifetime of a lock — is what de-duplicates concurrent loaders across replicas. ClaimLoadJob does its read-then-write under the advisory lock and nothing else: no network, file or gRPC I/O inside the guarded section, so a claim costs milliseconds no matter how long the resulting load takes. LastProgress is a heartbeat rather than a byte counter. A checkpoint load legitimately moves zero bytes for many minutes, so a reaper keyed on byte movement would reclaim a healthy job mid-load; byte progress stays the concern of load_deadline.go. A job whose heartbeat stops for longer than the orphan window is reclaimable, so a replica killed mid-load cannot wedge a model permanently. Failed jobs keep their row for a short grace so an immediately-following request reports the real cause instead of silently starting a fresh load of a model that just failed. No caller yet — the router moves onto this in the next commit. Assisted-by: Claude Opus 5 [claude-code] * refactor(distributed): run cold loads as jobs, outside the advisory lock Route wrapped the entire cold load — node selection, backend install, multi-GB staging and the remote LoadModel — in the per-model advisory lock. The lock's job is to de-duplicate concurrent loaders, a decision that takes milliseconds; holding it for the tens of minutes the resulting work takes is what turned a dedup mechanism into a cluster-wide outage for that model. Split it into a claim and a run. The claim is the only thing left inside the lock. The run is a background job owned by the claiming replica and bounded by the same progress-extended deadline as before; every other request for that model — local or on another replica — attaches as a waiter and is served the moment the model is ready, with no duplicate load and no lock contention. Waiters share one broadcast rather than an ordered queue: they all want the identical outcome, so ordering them would add fairness machinery that changes no result. The local channel wakes same-replica waiters instantly and a 2s DB poll is the authority, because a waiter on another replica has no channel to close. On wake a waiter re-runs the warm path rather than trusting the signal — the model may have been evicted in between. A waiter whose client disconnects returns immediately and the job keeps running; it belongs to the job record, not to the request. A failure is recorded on the row so every waiter reports the real cause, and the row survives briefly so the next request does not read "no job" as "not loading" and start a duplicate load of a model that just failed. The runner heartbeats the row on a fixed interval whether or not bytes are moving, which is what keeps a legitimately silent checkpoint load from being reclaimed as an orphan. Phase (installing/staging/loading) and placement ride to the heartbeat on the context, the same seam load_deadline.go already uses, so single-host paths are untouched. Non-distributed mode (no DB) keeps the inline load exactly as it was. Assisted-by: Claude Opus 5 [claude-code] * feat(distributed): bound the wait for a loading model and answer with progress A request whose model is cold-loading now attaches to the running job and is served the moment the model is ready. That wait has to be bounded: a held HTTP request cannot survive real infrastructure, and an ingress or LB idle timeout kills a twenty-minute request regardless of what LocalAI does. New LOCALAI_MODEL_LOAD_WAIT (default 60s) bounds the CALLER, never the load — the job keeps running either way. On expiry the request gets 503 with Retry-After and a structured body naming the model, the node, the phase, byte progress and an ETA. The `error` envelope keeps OpenAI clients working; `loading` is additive so they ignore it. The ETA comes from the job's own observed rate and is omitted rather than guessed until enough bytes have moved for that rate to mean anything: a confidently wrong ETA on a twenty-minute wait is worse than none. Retry-After is that ETA when known, clamped to [5s, 300s], and the wait budget otherwise. LOCALAI_MODEL_LOAD_WAIT=0 waits unbounded, for deployments with no proxy in front. Zero in the config struct still means "unset, use the default", so the CLI records the operator's zero as ModelLoadWaitUnbounded rather than losing the distinction. The distributed branch of ModelLoader.loadModel wrapped the router's error with %s, which flattened it to a string. Use %w: the typed error is what the HTTP layer keys the 503 off. Assisted-by: Claude Opus 5 [claude-code] * feat(api): add GET /api/models/{id}/load-status A client that receives 503 while a model stages onto a worker needs somewhere to poll. This returns the same `loading` object the 503 carries — phase, node, byte progress and ETA — or 404 when no load is running. Read-only and observability-shaped, so it is deliberately neither admin-gated nor feature-gated: it explains a 503 the caller just received, and hiding that behind a per-modality feature would make the explanation for a failed image request depend on chat permissions. It also gets no MCP tool, since there is nothing here an admin would manage conversationally. Registered on the surfaces from .agents/api-endpoints-and-auth.md: the swagger block (existing `models` tag, so /api/instructions needs no new area), the endpoint discovery maps in RegisterLocalAIRoutes, regenerated swagger, and the distributed-mode docs page. No FLAG_* usecase is involved, so capabilities.js is unchanged. Assisted-by: Claude Opus 5 [claude-code] * feat(ui): show cold-load progress in Chat and retry when the model is ready A chat request for a model that is still staging onto a worker now gets a 503 carrying live progress instead of an error. Render it: the composer shows the phase (installing / staging / loading), the node, the percent and the ETA, then polls load-status and re-sends the request the moment the model is ready. Reuses the staging progress idiom the page already had rather than inventing a second one — the two sources are folded into one loadProgress, with the load job winning because it is authoritative across frontend replicas and knows the phase, where the staging operation only knows about a byte transfer this replica happens to be performing. Waiting is bounded (three send attempts, ~30 min of polling each), so a load that never finishes still surfaces as an error rather than as a spinner nobody questions. An aborted generation stops the polling too. Assisted-by: Claude Opus 5 [claude-code] * fix(distributed): check warm-path cleanup errors The router moved legacy cleanup calls onto newly linted lines. Report cleanup failures while preserving the fallback to a cold load.

mudler's LocalAI [bot]andEttore Di Giacinto	0c9d4bf9cc	fix(vllm-cpp): build every CUDA architecture the platform can host (#11512) ... The vllm-cpp CUDA images were built for Blackwell only: 120a;121a on amd64 and 121a alone on arm64. vllm.cpp's own release archive builds ten architectures, so LocalAI shipped one or two of them. The failure mode is the problem. An unlisted card is not slower, it dies at the first request with "no kernel image is available for execution on the device", long after `backends install` reported success. That covers A100, A10/3090, L4/4090/RTX 6000 Ada, H100/H200, B200, B300, Jetson Orin and Jetson Thor, and it is how a Jetson Thor node was found serving nothing at all. amd64 now builds 80;86;89;90a;100a;103a;120a;121a and arm64 builds 87;90a;100a;110;121a, split by where the silicon exists: Jetson is arm64-only, desktop 120a is amd64-only, and 90a/100a are on both because of GH200/GB200. Triton-AOT stays ON for both, which the old comment said was impossible. It is not, at the version we pin: only maintainer REGEN needs a single arch, while the BUILDER path embeds every vendored cubin tree and selects by exact SM, so 87/103a/110/120a take the portable CUDA kernels and can never load a neighbouring cubin. Upstream ships its ten-SM archive that way. The CUDA 13 guard now covers both branches rather than amd64 alone. arm64 needs compute_121a just as much, and CI already builds it with 13. Cost is smaller than the arch count suggests, because gencode is per-source: fp4-mma still resolves to 120a;121a, and the CUTLASS scaled-mm kernels to one arch each, so the added architectures do not multiply the expensive translation units. Verified: flag generation checked for both branches, CUDA 12 still refused, CPU build untouched; both arch lists expanded through vllm.cpp's own vt_cuda_gencode_options and per-feature arch gating, and all six vendored Triton trees confirmed intact, at the exact pinned commit. A real compile is CI-only: there is no CUDA toolchain on the dev box.

mudler's LocalAI [bot]andEttore Di Giacinto	7a7fb00730	feat(ui): rebuild the import form on the restyled design language (#11461) ... The import page took the new palette in #11305 but kept its old layout, so it stayed a 760px column with the primary action detached from the form it submits. Two of the problems were outright bugs. The Import button carried no className at all, so the page's single most important control fell through to the user-agent button: system chrome, wrong radius, no design-system focus ring. The YAML button carried `fas fa-save fa-upload`, which sets Font Awesome as the button's own font family (its label text inherits it) and points two glyph classes at one ::before. On the layout: `page--narrow` is documented for "forms / single-record edit views", and in Advanced mode this page held a URI field, a six-section format guide, ten modality chips, nine preference fields, a key-value repeater and a YAML editor at `calc(100vh - 400px)`. The width was the symptom; one column was the disease. - `page--medium` with a work column and a format reference beside it. The reference answers the only question a first-time admin has and used to sit behind a chevron, closed by default. Below 1024px it becomes a disclosure rather than disappearing. - The source field is the hero: monospace, because it holds something you paste, and it carries its own Import button. That removes the hidden aria-hidden submit button that existed only because the real action sat outside the form. - Simple and Advanced are gone. They were ~80% the same surface, and the overlap cost a mode switch, a localStorage key and a three-button Keep/Discard/Cancel dialog whose only job was protecting state that switching modes would hide. One form with a collapsible options panel hides nothing, so none of it is needed. What genuinely differs is the kind of input, which is now the two tabs: a source, or YAML. - The size/VRAM estimate reports under the field that produced it instead of as a banner above the page header, and an import in flight gets the progress, phase and byte counts the poller already returned and the old status card threw away. - ModalityChips resolves its labels through the same `modality.*` keys as the dropdown it filters. It hardcoded English shorthand, so one modality carried two names on one screen ("Speech" on the chip, "Speech recognition" on the group it scrolled to) and seven locales had neither. Its inline styles and its pill radius move onto the design system. - Three inline styles go, including both conditional-padding hacks; the only one left is the progress bar's runtime width. Baseline 538 -> 535. Docs updated in the same change: the WebUI section described a Simple and an Advanced mode and told the reader to "Toggle to Advanced Mode". e2e: 426 passed. The mode-switch suite is replaced by one covering the tabs and the disclosure, and a new layout suite pins the width, the styled primary action, the absence of an icon-font button, the reference column at both widths, and the estimate's position.

mudler's LocalAI [bot]andEttore Di Giacinto	7b9167eaad	feat(llama-cpp): serve Qwen3-TTS through the llama.cpp backend (#11392) ... * fix(config): do not read a TTS speaker-encoder mmproj as vision support Qwen3-TTS on llama-cpp ships an mmproj holding the speaker encoder and code predictor. VisionSupported() treated any non-empty MMProj as proof of image input, so every such model would be advertised as vision-capable. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(llama-cpp): add TTS request option parsing helper Validates text and speaker reference presence and strictly parses the top_k / top_p per-request params, in a header with no llama.cpp or gRPC dependencies so the standalone C++ unit test gate picks it up. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(llama-cpp): range-check the TTS top_k and top_p request params Format validation alone let NaN, infinity and out-of-range values through. The consumer copies both values into the audio generation input unconditionally and only guards its separate sampler assignment with "> 0", a test NaN also fails, so a NaN reached llama.cpp with the guard never firing. top_k must now be >= 0 and top_p must fall within 0.0 to 1.0 inclusive, with the bound written as a negated in-range test so NaN is rejected rather than silently accepted. Also cover the two checks the suite could not previously kill: the whole-string check in the float parser and the int32 range check. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * chore(llama-cpp): bump pin to f9e832c10 and carry the TTS server task Picks up ggml-org/llama.cpp#26254 (Qwen3-TTS via mtmd) and #26536 (the short-input audio chunk fix). Adds 0002-add-server-task-type-tts.patch, the server-side half of the still-draft #26603, so TTS runs through the slot scheduler instead of racing it. Remove that patch when #26603 merges. The patch is rebased on top of the score patch: its tokenize-switch hunk collided with the SERVER_TASK_TYPE_SCORE case, and its lone SRV_WRN call passes no variadic argument, which the macro cannot expand. The score patch itself needed no refresh. Also fixes fallout from the bump in grpc-server.cpp: upstream dropped the per-slot n_ctx argument from server_schema::eval_llama_cmpl_schema. Only the schema branch loses it, since forks predating the server-schema split still expect the old argument list. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(llama-cpp): implement the TTS and TTSStream RPCs Both were declared in backend.proto but unimplemented. They now submit a SERVER_TASK_TYPE_TTS task and drain the response reader, the same shape PredictStream uses. The streaming path emits a leading sample_rate message and then raw PCM, because ModelTTSStream builds the WAV header itself; the non-streaming path emits a complete WAV to the requested dst. The streamed samples are converted from the pipeline's float32 to signed 16-bit first. MTMD_HELPER_GEN_AUDIO_OUTTYPE_PCM hands back floats, while the header ModelTTSStream writes announces 16-bit samples, so shipping the floats verbatim would decode as noise. prepare.sh and CMakeLists.txt now stage tts_request_options.h alongside the other grpc-server helpers, and register its standalone test with ctest the way passthrough_options_test is registered. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(llama-cpp): mask non-codec tokens for Qwen3-TTS generation The Qwen3-TTS gen-audio pipeline maps a sampled backbone token to a codebook row with an unchecked subtraction, in mtmd-helper-gen.cpp: inp.code0 = sampled - codec_0; For ggml-org/Qwen3-TTS-12Hz-1.7B-Base-GGUF the vocab is 155008 tokens, <|codec_0|> is 151936 and the codec codes end at 153983. The model's own tokenizer.ggml.suppress_tokens holds 1023 ids covering 153984..155007, every special above the codec range except <|codec_eos_token|> (154086) which stays reachable as the stop token. Nothing masks the text range 0..151935, so the backbone can sample a text token at any step, the subtraction goes negative, and ggml_compute_forward_get_rows aborts the whole backend process on GGML_ASSERT(i01 >= 0 && i01 < ne01). Complete the mask upstream started: bias every token below <|codec_0|> to -INFINITY for TTS tasks so only codec codes and the codec EOS remain reachable. The biases are appended to task.params.sampling.logit_bias, which common_sampler_init already merges with the model's suppress tokens into one llama_sampler_init_logit_bias, so no sampler is added to the chain. Measured cost is 0.082 ms per sampled token and 1.16 MB, set against a forward pass in the multi-millisecond range. It lands in launch_slot_with_task rather than in a route handler so that llama.cpp's own POST /tts and LocalAI's TTS/TTSStream RPCs are both covered, and <|codec_0|> is resolved from the vocab rather than hardcoded so a model without it is left alone. This is reproducible with upstream's own llama-tts and no LocalAI code loaded, aborting at frame 55 on Q4_K_M and frame 71 on Q8_0, so it is neither a quantization artifact nor an artifact of the gRPC adapter. Two further defects in the same draft pipeline still prevent end-to-end audio; they are independent of this one and are recorded in the task report for an upstream bug report.

That single defect accounts for every abort seen on this model, so 0003-mask-non-codec-tokens-for-tts.patch is removed rather than rebased. The mask changed the observed behavior, but it was perturbing a graph ordering bug rather than fixing a sampling one: at the new pin the whole path works without it. Keeping it would have meant carrying a 152k-entry logit bias, and rebasing it on every pin bump, for no benefit. Verified at 9de0fcf2b with only 0001 and 0002 applied, which both apply clean with no fuzz and needed no rebase: non-streaming HTTP 200, 410924 bytes, 8.56 s RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 24000 Hz streaming HTTP 200, 560684 bytes, 11.68 s, exactly one RIFF at byte 0, same format, which also exercises the float32-to-s16 conversion at runtime for the first time Pristine unpatched llama-tts at the same pin now also completes, 130 frames to a valid WAV, where it aborted at frame 55 before. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(llama-cpp): clear the TTS slot sequence between requests Only the first TTS request in a backend process succeeded. Every later one failed instantly, in about 0.13 s, with "TTS prompt processing failed" from step_prompt, regardless of streaming or non-streaming and regardless of the text. With LOCALAI_SINGLE_ACTIVE_BACKEND=true the process is kept alive between requests, so a deployment would have served exactly one utterance per backend start. The cause is missing KV hygiene, not anything in the gRPC adapter. TTS slots never enter the shared batch: pre_decode() returns early for them and process_tts_slots() drives them instead, so they skip the prompt-cache bookkeeping that clears a slot's sequence between requests. Nothing in the gen-audio path makes up for it: mtmd_helper_gen_audio_reset only clears host-side buffers, and the pipeline always decodes from position 0 into the sequence identified by slot.id. So the second task on a slot writes positions 0..N over the first task's tokens and llama_decode fails. Fix is one call to slot.prompt_clear(), the same helper the normal path uses, in the SERVER_TASK_TYPE_TTS branch of launch_slot_with_task before set_input. It goes into 0002 rather than a new patch file because it is a defect in the code that patch introduces, and the header now records it as ours so we know whether it still needs carrying if #26603 merges without it. Verified in one backend process, different text on every request: three consecutive non-streaming requests, three consecutive streaming requests, and an interleaved non-streaming, streaming, non-streaming, streaming run. All ten returned HTTP 200 with RIFF ... WAVE audio, Microsoft PCM, 16 bit, mono 24000 Hz, the streamed ones carrying exactly one RIFF header at byte 0, and every output measured as real speech rather than silence or a truncated fragment.

At the model's 12.5 Hz frame rate that is 40.96 s of audio, which a short input can trigger: one request in this session produced 40.96 s for a ten-word sentence. prepareTTSTask hardcoded n_predict to -1, so callers had no way to bound it. Add a max_frames key alongside top_k and top_p, parsed with the same strict whole-string parsing so a typo is an error rather than a silently truncated value, and rejected with a field-naming message when negative. 0 keeps the existing sentinel convention and means unset, so a request that omits it behaves exactly as before. Named max_frames rather than n_predict because frames are what the parameter means at a TTS endpoint: one frame is 0.08 s of audio. The 512-frame default is deliberately unchanged. Lowering it would truncate legitimately long inputs, which is a worse failure than an occasionally overlong one. Verified end to end on one text of thirty words: max_frames=25 HTTP 200, 96044 bytes, 2.00 s, exactly 25 frames max_frames=50 HTTP 200, 192044 bytes, 4.00 s, exactly 50 frames no max_frames HTTP 200, 572204 bytes, 11.92 s, stopped at its own codec EOS after 149 frames, unchanged behavior max_frames=-1 InvalidArgument "max_frames must be >= 0, got \"-1\"" max_frames=many InvalidArgument "max_frames must be an integer, got \"many\"" Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(llama-cpp): send the TTS sample rate up front, and tidy three review items Four items from the Task 4 review. Streaming first-byte latency. TTSStream sent the sample-rate reply only once the first audio result arrived, and a chunk needs a whole 72-frame window, roughly 5.8 s of audio and far longer in wall time on CPU. The Go side blocks on that reply before it can emit the WAV header, so a streaming client sat at zero bytes for the whole stretch. The rate is a property of the loaded model and is available synchronously from mtmd_gen_audio_get_info, so it now goes out immediately after post_task and the rate_sent bookkeeping is gone. Measured on a warm model, first byte drops from 30.48 s to 0.014 s, and the output is still a valid WAV with exactly one RIFF header at byte 0. Unchecked close. The non-streaming path ignored ofstream::close(), so a failure that only surfaces on flush was reported as success while leaving a truncated file at dst. It now returns INTERNAL like the other write failures. Wrong comment on set_lang. gen_audio::inp::get() already maps a stored blank to nullptr, so our guard is behavior-preserving, not behavior-fixing. The comment claimed otherwise; the code was right. Repetition penalty. penalty_last_n = -1 is inert at this pin, because llama_sampler_init_penalties clamps it with std::max(penalty_last_n, 0) and then builds a disabled sampler, so the 1.05 penalty never applies. Upstream's README attributes looping to a missing repeat_penalty, so it was worth testing as a root-cause fix for the model running to the frame cap. Dropping the line lets the sampling default of 64 apply, which was confirmed in the sampler chain trace as penalty_last_n = 64 with repeat_penalty = 1.050. Over 15 uncapped short requests each way it did not help: 0 of 15 ran to the cap with the penalty inert, 1 of 15 with it active. Both lines are therefore kept for parity with upstream's draft, and a comment now records that the pair is inert and why, so the next reader does not believe a penalty is applied. max_frames remains the way to bound output.

GuessUsecases has no FLAG_VISION branch, so it falls through to true for any chat-ish model. That is not just a wrong answer at the call site: syncKnownUsecasesFromString rewrites KnownUsecaseStrings from HasUsecases, and the loader calls it more than once per config file, so the guessed FLAG_VISION is written out and parsed back into KnownUsecases as if the operator had declared it. Give GuessUsecases a FLAG_VISION branch that defers to the same explicit signals VisionSupported uses. Second, llama.cpp builds an mtmd context for the speaker-encoder projector and reports its media marker on the first chat probe, which resurrected vision after the model had been used once. Apply the same declared-TTS exemption to MediaMarker that the mmproj check already had. Verified against the qwen3-tts-llamacpp-q4 gallery entry: no vision capability and no image input modality, before load, after a TTS request, and after a chat probe.

Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(config): register llama-cpp as a TTS and voice-cloning backend The branch taught the llama-cpp backend to serve Qwen3-TTS and shipped two gallery entries for it, but never told the capability table. llama-cpp still declared only the text RPCs and usecases, so: - VoiceCloningForModel returned nil at the capability check, before it ever reached the model's own tts.voice_cloning override, and /tts answered 400 "selected model does not support reference-audio voice cloning" for any localai://voice-profiles/... voice. No model YAML could opt back in. - GET /api/backends/usecases did not list tts for llama-cpp, so the gallery greyed out the TTS filter for the entries this branch adds. - The React TTS page saw voice_cloning: null and kept both models out of the Voice Library. Add the TTS RPCs and usecase, and the reference-audio contract. The contract needs narrowing, because the per-backend switch in VoiceCloningForModel ends in a permissive default: an unnarrowed entry would have advertised reference-audio cloning on every GGUF chat model in the gallery. Narrow on the declared TTS usecase rather than the model name. The TTS checkpoints are the only llama-cpp models carrying known_usecases: [tts]; name matching would have to guess at third-party repacks, and "base", the substring the neighbouring Qwen and vLLM cases key on, is a routine word in text-model names. The check reads the declared bit directly instead of going through HasUsecases, which falls through to GuessUsecases and would hand the decision to a heuristic that never had a llama.cpp TTS model in mind. DefaultUsecases stays [chat]: a bare GGUF served by llama.cpp is a chat model, and both the gallery filter and the importer read that field.

Nemotron 3 Nano Omni is a multimodal understanding model: image, video and audio in, text out. Declaring that is what the sibling vllm-omni-qwen3-omni-30b already does. known_usecases gains vision only. FLAG_VIDEO is video GENERATION, an output modality, and this model generates none; video and audio input belong in known_input_modalities, which is where AudioInputSupported and VideoInputSupported read them from. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(importers): import a Qwen3-TTS GGUF repo as TTS, not chat The llama-cpp importer hardcodes known_usecases: [chat] and assigns any mmproj-matching file as a vision projector, so ggml-org/Qwen3-TTS-12Hz-1.7B- Base-GGUF imported as a chat model with vision. Both fields were wrong, and the model was unreachable from /tts and from the Voice Library. Filenames cannot fix this. A Qwen3-TTS repo has the exact shape of a vision repo, one backbone GGUF plus one mmproj-*.gguf, so the projector's own header is the only honest signal: mtmd writes clip.has_gen_audio_encoder for the projectors it can drive as a speech pipeline and refuses to build one without it. Probe the selected mmproj for that flag, reusing the range-fetch the MTP detection already does, and declare tts when it is set. The mmproj assignment then stops reading as vision on its own, since a declared-TTS model already exempts its projector from vision detection. The probe is best-effort like the MTP one: a network blip leaves the chat default in place rather than failing the import. Verified against the real artifacts on disk: the Qwen3-TTS projector reports gen-audio, its backbone does not. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(llama-cpp): stop non-TTS models crashing on the new pin Two regressions, both hit every ordinary llama-cpp model and neither was caught locally because every test on this branch loaded a TTS model. The first is a null dereference. server_slot::tts_ctx::reset() called mtmd_helper_gen_audio_reset() unconditionally, but the gen-audio pipeline is only allocated for models carrying a gen-audio mmproj, and upstream's implementation reads ctx->pipeline before null-checking anything. Since server_slot::reset() runs during slot initialization for every model, any non-TTS model segfaulted the backend the moment it loaded. Guard the call on the is_supported() predicate already defined beside it, and keep the plain field resets unconditional. The second is unrelated to TTS and came in with the pin bump. PredictOptions.Penalty is a bare proto float, so a caller that names no repetition penalty sends 0 rather than omitting the field. Since 9de0fcf2b, common_sampler_init() rejects a non-positive penalty_repeat outright because it would divide logits by zero, turning every such request into "Failed to initialize samplers". Treat 0 as unset and leave llama.cpp's own neutral default in place. Verified with the same suite CI runs, which is what caught both: tests/e2e-backends passes 6 of 6 including the load and predict specs that were red. Qwen3-TTS still synthesises on both paths, 24 kHz mono 16-bit WAV with exactly one RIFF header on the streamed output.

mudler's LocalAI [bot]andEttore Di Giacinto	a0f50b2af2	feat(vllm-cpp): serve MiniMax-H3 video+audio generation (#11424) ... * feat(vllm-cpp): serve MiniMax-H3 video+audio generation vllm.cpp's C ABI grew a video slice (ABI v12): a second engine handle loaded from the MiniMax-H3 checkpoint SET, one blocking generate, and a composed ffmpeg argv the caller execs. This wires that into LocalAI's existing /video endpoint, so `vllm-cpp` now serves both text and video and a clip comes back as an MP4 with a real audio track rather than a silent render. The video engine is a separate handle rather than a mode of the text one because H3 is not a model directory: the DiT, the text encoder and two VAEs are separate artifacts, and vllm.cpp has the two loaders refuse each other's checkpoints. `Load` takes the video branch when the config declares any of the video options; `parameters.model` is the DiT and the rest of the set is named in `options:`. Three details are worth calling out because getting them wrong is expensive: - The partition is DECLARED, not detected. The community quantisations strip the release metadata and the FL2VA and Ref2VA DiTs are byte-structurally identical, so the engine refuses to generate until it is told which it has. Worse, a mismatch does not fail cleanly: a reference passed to an FL2VA DiT renders for hours and returns a coloured lattice over the frame. The backend refuses that combination up front instead. - ffmpeg comes from the host. libvllm writes frames plus a WAV and composes the mux argv, then spawns nothing - that process boundary is upstream's decision. The backend execs it, the same arrangement vibevoice-cpp uses for transcoding, and ffmpeg also converts a start_image upload into the binary PPM at the exact output canvas the engine requires. - It is slow. Roughly 176 s per denoise step at the default 1344x768 canvas on a 20-SM device, so the 50-step default is a multi-hour job. Nothing on this path imposes a deadline. The /video endpoint no longer forces 512x512 when the request omits the geometry. Every video backend already supplies its own default for a zero (512x512 for stablediffusion-ggml, 1280x720 for diffusers, 832x480 for longcat-video, 1344x768 for H3), so the hardcoded value only ever overrode the model's trained canvas with one three of the four were never trained at. Moving the engine pin from ABI v10 to v16 also grows the text vllm_model_params mirror by the v14 device field and the v16 KV-sizing knobs. LocalAI sets none of them - 0 is the pre-v14 engine byte for byte - but the struct SIZE is part of the layout contract, so leaving them out would have vllm_engine_load read past the allocation. Gallery: `minimax-h3-fl2va-q4` installs the Q4_K_M FL2VA set (~40 GB across five weight files plus the two VAE configs that carry the latent statistics). Assisted-by: Claude:claude-opus-5 golangci-lint yamllint go-vet * fix(vllm-cpp): unbreak the Darwin build at the new engine pin src/capi/vllm_c.cpp opens one `extern "C" {` for the whole ABI surface, so file-local helpers declared inside it inherit C linkage. The video slice added one that returns std::string, which Apple Clang reports as -Wreturn-type-c-linkage and vllm.cpp's target-local -Werror turns into a build failure. GCC and upstream Clang do not diagnose it, so only the metal-darwin-arm64 job saw it. Suppress it the same way this Makefile already suppresses Apple Clang's -Wgnu-folding-constant on the Metal build. The helper is never called across the boundary so the warning describes no hazard here, but it is a real upstream wart: the fix belongs in vllm.cpp, hoisting the helper above the extern "C" block, and this flag should go when a pin carrying that fix lands. Assisted-by: Claude:claude-opus-5 * fix(vllm-cpp): patch the engine clone instead of the warning flag The -Wno-return-type-c-linkage added in the previous commit does nothing. vllm_cpp_set_warnings adds `-Wall -Wextra -Werror` as PRIVATE target options, so they land after anything CMAKE_CXX_FLAGS contributes, and -Wall re-enables the -Wreturn-type group that -Wreturn-type-c-linkage belongs to. The darwin job failed again on the same line, which is the evidence: a consumer cannot wave this off from outside the engine. Position is the only fix, so carry it as a patch against the pinned SHA, the way longcat-video patches its own upstream. It hoists the helper above the `extern "C" {` that gives it C linkage; it is file-local and never called across the boundary, so nothing else moves. `git apply` is unguarded on purpose: a patch that stops applying must fail the clone loudly, because the alternative is a pin that silently ships without a fix it is documented to carry. The patch header names what retires it - a pin carrying the fix upstream, where it belongs. Verified by applying the patch with `git apply` to the exact blob at the pinned SHA and diffing the result against the intended file. Assisted-by: Claude:claude-opus-5 * chore(vllm-cpp): bump the engine pin to ABI v17 and drop the vendored OrEmpty patch The OrEmpty linkage fix this backend carried as patches/0001-* landed upstream (mudler/vllm.cpp#195, 7534da65), so the patch has done its job. It is deleted rather than left in place: the Makefile applies patches/*.patch unguarded and documents that "a patch that no longer applies must FAIL the clone", so keeping it against fixed source would break the build the moment the pin moved. Bumping the pin and deleting the patch therefore have to be the SAME change. Pin f921062b -> 776c56f1 (current vllm.cpp main). That range also carries the engine's ABI v17 (vllm_server_main: the OpenAI server published on the public surface). registerLib compares the library's vllm_abi_version against `abiVersion` for EXACT equality, so the constant moves 16 -> 17 in the same commit or every load fails with an ABI mismatch. The bump is safe for the layout assertions in video_test.go: diffing include/vllm.h across the two pins shows zero struct-field changes -- v17 adds one function declaration, the version macro and a doc comment, nothing else -- so every unsafe.Offsetof in the video params test still holds. Assisted-by: Claude Code:claude-opus-5 [ClaudeCode] * chore(vllm-cpp): re-pin to pick up the VLLM_CPP_SERVER=OFF link fix The previous pin carried vllm.cpp's ABI v17 (vllm_server_main) but not the guard that makes it link when the server is compiled out. This backend builds libvllm with VLLM_CPP_SERVER off, so the darwin lane failed at the dylib link with vllm::entrypoints::openai::VllmServerMain undefined. Fixed upstream in mudler/vllm.cpp#202: the C entry point is now guarded, so the symbol is still exported (ABI v17 stays resolvable for dlopen) while the no-server arm reports the missing capability instead of dragging in a translation unit that was never compiled. Verified upstream in BOTH arms before re-pinning: SERVER=ON builds and runs, and SERVER=OFF configures, links, produces libvllm.so, and `nm -D` shows vllm_server_main exported next to vllm_video_generate and vllm_transcribe.

Adiraandlocalai-org-maint-bot	ab52813342	feat(modelartifacts): support bounded parallel Hugging Face file downloads (#11162) ... * feat(modelartifacts): support bounded parallel Hugging Face file downloads Closes #11114. Snapshot materialization fetched every file through the sequential executor in DownloadFilesWithContext, so a repository split into many shards spent most of its wall clock in per-file request latency rather than moving bytes. Add DownloadFilesWithConcurrency, an errgroup with SetLimit, and keep DownloadFilesWithContext as a wrapper that passes a limit of 1. That leaves the two non-artifact callers (core/gallery and the model config loader) on exactly the path they had: tasks still run in slice order, and the first failure still returns before any later task starts. Only whole files run in parallel. A single file is never split, so the .partial resume machinery and the per-file SHA check in downloadTaskWithRetry are untouched. Two details the parallel path forced: - completedBytes becomes an atomic.Int64. Several AfterDownload hooks add to it while other files' progress callbacks read it; without this the race detector reports three races on the new specs. - The caller's status callback is serialized. The sequential path gave it an implicit guarantee of never being entered twice at once, and it belongs to the caller, so the executor keeps that promise rather than pushing locking onto every caller. AfterDownload is deliberately not serialized -- it does the verify-and-promote work that parallelism exists to overlap. Manifest order needed no work: each hook already writes its own manifest.Files slot by snapshot index, so entries stay in snapshot order whatever the completion order. A spec now pins that. The default is 1, unchanged behaviour. A shared models volume is often the bottleneck rather than the link, so raising it is a deployment decision; --artifact-download-concurrency and LOCALAI_ARTIFACT_DOWNLOAD_CONCURRENCY expose it on both `run` and `models install`. Not done here, per the issue: no chunk-level parallelism within a single file, and no throughput measurements across concurrency 1/2/4/8 -- that needs a representative sharded repo and a real link. Assisted-by: Claude:claude-opus-5 go-test gofmt Signed-off-by: Adira Denis Muhando <dennisadira@gmail.com> * feat(modelartifacts): expose download concurrency in settings Follow-up to review feedback on #11162: - The CLI flag and docs no longer describe the limit as Hugging Face specific. It applies to any artifact source, as @mudler pointed out. - artifact_download_concurrency is now a persisted runtime setting and is editable from the WebUI, so it can be changed without a restart. The manager's limit becomes an atomic.Int64 behind SetDownloadConcurrency, because a live runtime setting can be updated while a materialization is already in flight. Injected materializers stay compatible through an optional setter interface, so a manager that does not implement it is simply left alone. Verified before taking this on: go build, go vet and go test -race all pass for pkg/modelartifacts, pkg/downloader and core/config. The React UI builds with vite, artifact_download_concurrency is present in the built Settings chunk, and eslint reports the same 8 pre-existing warnings on Settings.jsx as it does without the change.

mudler's LocalAI [bot]andEttore Di Giacinto	9a6156d808	feat(nemo-speech-cpp): add the NVIDIA NeMo-Speech.cpp backend (#11406) ... * feat(nemo-speech-cpp): scaffold the backend and upstream build Adds the backend skeleton and the NeMo-Speech.cpp build, pinned at 2e12e2def8a98ed06666f7ee3ca94e7193e04be4. The Go side is deliberately a stub: it dlopens the runtime and starts the gRPC server, later work fills in the symbol table and the model logic. Three details of the upstream layout differ from what the plan assumed, and the build reflects the real tree: * The TTS C ABI ships as libnemo_speech_tts, not libnemo_speech_tts_c. Upstream compiles c_api.cpp straight into the implementation library and only aliases the nemo_speech_tts_c CMake target, so no _c object exists on disk. ASR and NMT do build a real _c shim. * Shared objects land in build/bin, since upstream points CMAKE_LIBRARY_OUTPUT_DIRECTORY at ${CMAKE_BINARY_DIR}/bin. * The ASR and NMT _c shims carry a DT_NEEDED on libnemo_speech_asr and libnemo_speech_nmt, so those are staged and packaged alongside them. Otherwise dlopen fails at startup. The ggml patch step uses an order-only prerequisite. cmake writes into the checkout and bumps its mtime past the sentinel, which would otherwise re-run git apply over an already-patched tree and break every incremental build. Assisted-by: Claude Code:claude-opus-5[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(nemo-speech-cpp): make 'build' produce the package and bundle the ITN stack Addresses the review of the scaffold commit. backend/Dockerfile.golang runs 'make -C backend/go/$(BACKEND) build' and then copies package/ into the final image, so 'build' has to end with a populated package/. It only staged shared objects, which would have shipped an image with no binary and no libraries at all. The old staging recipe is now stage-libs and the chain is stage-libs, nemo-speech-cpp-grpc, package, build, matching every sibling Go backend. Text normalization was packaged incorrectly. nemo_speech_text_normalization is STATIC but links sparrowhawk, fstfar and fst PUBLIC, so they land as DT_NEEDED on libnemo_speech_asr.so, and they live in a project-local prefix that nothing else provides. WITH_NORM stays ON by default on Linux, since normalization is a wanted feature. Instead stage_libs now copies .deps/itn/lib when WITH_NORM=ON, and package.sh bundles it. Staging that prefix is still not enough on its own: Sparrowhawk drags in protobuf, re2 and absl, which neither build_itn_deps.sh nor package-system-libs.sh provides. Rather than hard-code another hand-maintained list, package.sh now walks the DT_NEEDED entries of everything staged and copies whatever is unresolved, skipping the core set and the GPU set that the shared scripts already own. It fails at package time, not at first dlopen, when something cannot be resolved. On a WITH_NORM=OFF build the closure is already complete and it copies nothing. Restore CGO_ENABLED=0 on the Go build to match whisper, parakeet-cpp and omnivoice-cpp. Note that purego reaches dlopen through fakecgo, so the binary is dynamically linked either way; what the flag changes is the NEEDED set, and lib/ld.so routing in run.sh exists precisely because the binary is not static. Replace the hand-rolled .patched sentinel with upstream's scripts/apply-ggml-patches.sh. It applies the series in filename order, exits non-zero when a patch does not apply, and detects "already applied" by comparing the full-series tree hash rather than an mtime, so it is safe to run every time and there is no sentinel left to go stale or to wedge the build when deleted. It is wired as an order-only prerequisite so running it does not force a relink. Also: correct the package.sh header, which claimed three shared objects when there are five and none of the TTS ones carry a _c suffix; give 'make test' the LD_LIBRARY_PATH the dlopen tests will need; document that a NEMO_SPEECH_VERSION bump needs 'make purge'; and extend 'clean' to remove package/ and the ITN libraries.

The dependency-closure guard failed open. Its glob expands once per pass, so each pass advanced the closure by exactly one level, and the fixed count of five passes then fell out of the loop without checking whether anything remained. An eight-deep chain packaged six libraries, exited zero and reported success. That is the case the guard was written for: asr to sparrowhawk to protobuf to absl already runs several levels deep, so a WITH_NORM build could ship missing its deepest libraries and fail at first dlopen. The loop now runs until the staged set stops growing, and exhausting the bound is a hard error rather than a silent exit. For the same reason, a build image with neither readelf nor objdump no longer warns and skips. It cannot show the package is complete, so it refuses to ship it. The guard is entered only when there is something to check, so an empty package cannot trip the new error. Dockerfile.golang installed ninja-build only in the Vulkan branch while this Makefile runs cmake -G Ninja unconditionally, so the CPU, cuBLAS and L4T images could not configure at all. ninja-build moves to the common apt list; it does not change CMake's default generator, so it is inert for the other backends. gcc-12 was nowhere in the tree, yet WITH_NORM defaults ON and build_itn_deps.sh needs it, so the committed default was unbuildable in CI. Install it, with the protobuf, absl, re2 and autotools that Sparrowhawk and OpenFST need, gated on BACKEND so the other Go images do not carry it. The list follows upstream's own docker/Dockerfile, trimmed of the gRPC, portaudio and python entries a BUILD_GRPC=OFF build does not use. Text normalization stays ON: downgrading it silently would ship a backend advertising a feature it lacks. Also: make test depend on stage-libs, so LD_LIBRARY_PATH is not an empty directory on a clean tree, and add an engine target so Dockerfile.golang's cacheable prebuild layer is not skipped and a CUDA build stops recompiling all of upstream on every Go-side change.

Dockerfile.golang installs protoc 27.1 into /usr/local/bin, ahead of /usr/bin, while libprotobuf-dev is the distro's 3.21 on noble and 3.12 on jammy. Sparrowhawk resolves protoc from PATH at make time (configure.ac uses AC_CHECK_PROG, so PROTOC substitutes to the bare word, and src/proto/Makefile.am invokes it) and commits no pregenerated stubs, so the rule always runs. Code generated by 27.1 includes google/protobuf/runtime_version.h and a PROTOBUF_VERSION guard the older headers lack, so the WITH_NORM build could not complete. Pin PROTOC to the apt one for that step; configure documents that a pre-set value wins. The apt protoc and libprotobuf-dev come from one source package at one version, which is the property that makes this correct. The text-normalization stack is now a target keyed on a file build_itn_deps.sh actually produces, rather than a side effect of the runtime library rule. As a side effect make could not see whether it existed, so once the library was up to date the script could never run again: a tree built WITH_NORM=OFF could not move to ON, and make test hard-failed with no escape but a full 345 MB clean. It is now built on demand and reachable on its own as 'make itn'. Staging keys on the prefix existing rather than on WITH_NORM, so it stages what the tree actually built, and package.sh's closure guard remains the backstop. An already-configured build tree also now wins over the platform default, so a tree built WITH_NORM=OFF is not silently reconfigured to ON by a bare make test, which is what demanded gcc-12 from developers who chose not to have it. An explicit WITH_NORM= on the command line still overrides both, and the ITN rule preflights for gcc-12 with an error that names the alternative. Move ninja-build out of the shared apt layer into the existing BACKEND-gated block. Dockerfile.golang serves 225 matrix entries and only this backend configures with -G Ninja, so the common list is byte-identical to master again and no other image loses its cache. Drop libabsl-dev and correct the comment that justified it. No base image here ships protobuf 25, so nothing needs the absl split, and the cmake glob looks in /usr/lib rather than the multiarch directory Ubuntu actually uses, so the package could never have contributed anything.

The nemo-speech-cpp apt block sat immediately after the shared apt layer, above the Vulkan SDK build, the CUDA and ROCm installs, the Go toolchain and the protoc download. Docker keys each layer on its parent, so inserting a step there re-keys everything below it: a byte-identical shared layer is not enough, and merging as it stood would have forced all of those to re-execute once for every Go backend image. Move it down beside the existing opus, crispasr and sherpa-onnx gates, which sit after those layers for the same reason. Checked the ordering both ways before moving. Nothing between the two positions uses these packages: the Vulkan and opus blocks install their own ninja and pkg-config, go install protoc-gen-go needs the Go toolchain rather than protoc, and the protoc 27.1 step is a release-binary download that needs neither protobuf-compiler nor libprotobuf-dev. Nothing in the block needs anything those layers provide; it uses only apt, and the mirror rewrite from the first RUN persists in the image. It also runs no update-alternatives, so the default compiler stays untouched for later layers. The diff against master is now a single additive hunk with no shared layer touched. Also preflight ITN_PROTOC. configure gates a preset PROTOC on test -n alone, so a path that does not exist is accepted and the error surfaces much later as a bare "No such file or directory" from inside make -C src/proto. The pin introduced that failure on a box whose only protoc is in /usr/local/bin, which worked before. Check it alongside the gcc-12 check and name the ITN_PROTOC= override in the message.

That branch of resolve() had no spec: dropping the guard left every spec green while parseOptions started returning the models directory itself. Add the spec that fails without the guard. A known key with an unparseable value is a typo, not a config from a newer backend, and "gpu:banna" failed expensively: the model loaded, produced correct output, and ran on CPU with no signal anywhere. Log it. Unknown keys stay silently ignored, which is what keeps configs forward compatible.

Two of the bindings differ from the plan because the headers do. The plan's nemo_speech_diar_segments signature omits the segmentation-config pointer that diar.h declares as the second parameter, which would have shifted the output buffer, the capacity and the count pointer one position each. And nemo_speech_diar_stream_push_f32 was missing from the symbol table although standalone diarization cannot work without it. Also close the two panic and equality gaps left in family.go: ValueString panics on a mistyped general.architecture, and the self-codec guard compared a Cleaned candidate path against an uncleaned one, so a doubled separator let the primary GGUF be selected as its own codec. Assisted-by: Claude Code:claude-opus-5[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(nemo-speech-cpp): run the ABI specs in CI and refuse to skip them The layout assertions were inert. TEST_PATHS does not cover this backend and the per-backend list in test-extra had no entry for it, so nothing invoked the package's tests. Add it next to depth-anything-cpp, supertonic and vllm-cpp, the group whose own test target carries its build prerequisites; stage-libs already pulls the native build chain, so no prepare-test-extra entry is needed. The skip guard was also loader-inconsistent: librariesPresent stats bare filenames relative to the working directory while openLibraries resolves them through the loader search path, so any invocation other than make test skipped every library-backed spec and still reported green. NEMO_SPEECH_REQUIRE_LIBS=1 turns that into a failure naming the directory and the remedy, and the Makefile test target sets it. Unset, the plain skip survives so a developer without a build can still run the pure-Go layer specs. Trim the default-value fingerprint from roughly forty assertions to eight. It was pinning tunables such as threads and flush_partial_chunk, so a legitimate pin bump would have failed with a message reading like a layout error. What survives is only header-documented contract: the lone non-zero max_alternatives, the run of -1 sentinels and the zero that witnesses where it stops. Verified the narrowed spec still catches a mirror and offset table corrupted in lockstep, which is the one class only this layer sees.

The family is committed only once its loader has succeeded. A load that fails part way through would otherwise leave the gate open on a handle that was never created. cstr uses runtime.Pinner rather than an ordinary Go allocation. The address crosses the ABI as a uintptr, which the collector does not trace, so incidental reachability through the release closure is not a guarantee: a caller discarding that closure could have the bytes collected before the create call reads them. Pinning is the sanctioned mechanism, makes the release function do real work, and turns a dropped release into a loud leaked-Pinner panic instead of silent corruption. Free overrides the base no-op to destroy the handle and reset the family. Every family owns C memory only its own destroy entry point can release, so without this an unloaded model leaks an acoustic model. Assisted-by: Claude Code:claude-opus-5[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(nemo-speech-cpp): pin the load ordering, close the engineMu race Three review items, plus a defect the race detector turned up. The spec covering "no family selected after a failed load" wrote junk to a .gguf, so Load returned at ggufArchitecture before a family was ever chosen and the assertion was vacuous. Generalised the GGUF test helper to take a string architecture, and added a spec that loads a magpietts GGUF with no sibling codec, so familyFor succeeds and discoverTTSAssets then fails. It self-guards on ggufArchitecture so it cannot degrade back into the earlier path. requireFamily read n.fam unlocked while Free wrote it under engineMu, which the race detector confirms is a real race. pkg/grpc/server.go calls Free without the backend lock every other RPC holds, so teardown can land mid-request. withEngine now takes the lock, checks the family and runs the body under one acquisition; two would leave a window for Free to destroy the handle between check and use. The locking protocol is stated in both directions for the RPCs still to be written. Running -race also enables checkptr, which aborts on cstr's pointer being read back by goString: converting a uintptr to a pointer is fatal whenever the address lands in a Go allocation, so a pinned Go buffer can never be dereferenced from Go. The pointer is for C alone. Both helpers now document the one-way contract, and goString is tested against a real C-owned string by rebinding the version symbol to return a raw char*. Assisted-by: Claude Code:claude-opus-5[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(nemo-speech-cpp): implement offline transcription Create the ASR recognizer in loadASR and serve AudioTranscription. Segment times are int64 nanoseconds, not seconds: the proto field is an int64 that core/backend reads straight into a time.Duration, while the runtime reports word offsets in milliseconds. Words are grouped into one segment per consecutive speaker run, with the 1-based speaker tag carried through and 0 (untagged) left unlabelled. The whole RPC body runs inside withEngine so the family check and the C calls happen under one acquisition of engineMu. Free runs without the backend lock, so checking the family and then relocking would let a teardown destroy the handle in the gap. The audio decode is inside the closure too, which costs nothing: base.SingleThread already serialises this backend's RPCs. recognizeF32 guards zero-length PCM. &pcm[0] panics on an empty slice, so Go never reaches the C side's own "empty audio" rejection, and a silent clip or a truncated upload is ordinary input. pkg/utils has no WAV decode helper, only the ffmpeg normalisation, so audio.go pairs AudioToWav with go-audio the way parakeet-cpp does. It returns the sample rate rather than a duration, since the C API resamples off that number. Also closes the write-side half of the race Task 5 fixed on the read side: Load now holds engineMu across the family switch and the n.fam commit, matching Free. The loaders still must not take it. Assisted-by: Claude Code:claude-opus-5[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(nemo-speech-cpp): implement streaming and live transcription AudioTranscriptionStream drives a whole clip through the cache-aware streaming API in 100 ms pushes, emitting each finalized utterance as a delta and closing with the assembled result. AudioTranscriptionLive serves the bidirectional RPC over the same session: config first, a ready ack, deltas with word timings as utterances land, and a terminal result when the caller closes its send side. Both wrap their body in withEngine, so a stream holds engineMu for its whole life and Free waits on it rather than destroying the recognizer underneath a half-finished stream. That makes the way out load-bearing: the file loop honours the request context between pushes, and the live loop ends when the host closes the request channel, so a disconnected client cannot pin the model against unload. Only finals become deltas. The runtime applies punctuation and inverse text normalization on finals only, so a final rewrites the utterance rather than extending its interim, and delta on the wire is newly-finalized text that consumers concatenate. Forwarding interims would duplicate and mispunctuate every utterance. The four streaming entry points sit behind an asrSession interface. No NeMo GGUF is small enough to keep in the tree, so without that seam the need-more-audio drain would have no test at all: nemo_speech_asr_stream_next reports OK with a NULL handle when it wants more audio, which is a pause rather than an end, and reading it either way round drops results or spins forever. Also folds in three items from the offline transcription review: - empty audio is now refused before anything crosses the ABI, not inside recognizeF32. The added integration spec caught the old ordering panicking on an unbound entry point instead of failing; - an undecodable sample rate is an error rather than 0, which this runtime reads as "already at the model rate" and would have made a wrong rate silently pitch-shift the audio; - AudioTranscription guards its result pointer instead of relying on an unstated invariant. Assisted-by: Claude Code:claude-opus-5[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(nemo-speech-cpp): make live deltas concatenate and fill segment words runLive wrote the inter-utterance separator into the accumulated transcript but emitted the delta without it, so a two-utterance turn sent "one." and "two." while the terminal result read "one. two.". The live consumer is the one that really concatenates: the realtime semantic-VAD path joins the accumulated deltas with the empty string and clears them only at a turn reset, never at an endpoint, so the running caption read "one.two.". The separator now goes into the delta, as it already did on the file path, and the terminal text is the verbatim concatenation rather than a trimmed rebuild. TranscriptSegment.Words was never populated, so a request asking for timestamp_granularities ["word"] came back with no words at all even though the timings were decoded. wordsToSegments now attaches them, gated on the granularity the same way parakeet-cpp gates it, so a transcript that did not ask for word timestamps does not pay for them. Also: the final that comes back from the tail flush no longer claims an end-of-utterance. It is the end of the stream, not a user yielding the turn, and eou is what the realtime turn detector acts on. The comment explaining why interims are suppressed led with the runtime's postprocessing. The wire contract is the stronger reason and now comes first: consumers concatenate deltas, so forwarding a growing hypothesis assembles to "hehellhelloHello.". The postprocessing only explains why no diffing trick would rescue them. It is also ITN and strip_formatting rather than punctuation, which is off by default here. Assisted-by: Claude Code:claude-opus-5[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(nemo-speech-cpp): implement standalone diarization loadDiarizer creates the Sortformer diarizer and Diarize serves the RPC over a diarization stream: decode, chunked push, finish, then the count-then-fill segments protocol. nemo_speech_diar_segment carries start_time and end_time in SECONDS already, not frame indices, so no conversion happens on the way to DiarizeSegment.start/end and the model's seconds-per-frame is not involved at all. The speaker label is the runtime's 1-based tag as a decimal string, matching what wordsToSegments emits on the ASR path, so the same speaker reads the same way whether a caller diarized a file or transcribed it. The six frame-geometry overrides are written as -1 rather than left zero. c_api.cpp applies left_context_frames when it is >= 0 while every other override needs > 0, so a zeroed config would silently pin the left context to zero and change the model's streaming geometry. nemo_speech_diar_segments writes *count before it rejects a buffer that is too small, so a rejected fill still reports the size to retry with. collectSegments uses that rather than truncating, bounded at four attempts because the RPC holds engineMu for its whole body and an unbounded retry would block an unload behind it. Two DiarizeRequest knobs map onto the segmentation config, and the proto and header names cross over: min_duration_on is the C min_duration_sec and min_duration_off is the C min_gap_sec. Six fields have no equivalent in this pipeline and are logged rather than dropped in silence: num_speakers, min_speakers and max_speakers (Sortformer's capacity is fixed by the checkpoint), clustering_threshold (there is no clustering stage), include_text (no ASR here) and threads. The empty-PCM guard fires before the stream is opened, so a silent clip never reaches a purego entry point that would dereference &pcm[0]. Assisted-by: Claude Code:claude-opus-5[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(nemo-speech-cpp): pin the diarizer geometry sentinels and cap the segment buffer The six frame-geometry overrides were written as -1 with nothing asserting it. c_api.cpp applies left_context_frames at >= 0 while the other five need > 0, so a dropped sentinel there pins the model's left context to zero, and the struct keeps exactly the same shape, which is all the layout assertions can see. Extracting diarModelConfig makes the values assertable: five specs now pin all six frame fields, the device index, the declared size and the NULL preset, each frame field on its own line so a missing sentinel names itself. distinctSpeakers had a spec with three segments over three distinct labels, which len(segs) satisfies just as well as the real thing. Four segments over three labels makes it a spec that can fail. collectSegments sized its buffer straight from a count the C side reported, and make() panics rather than erroring on a length it cannot satisfy, so an uninitialised size_t coming back across the ABI killed the backend process instead of failing one request. A ceiling of 2^22 segments, upwards of 93 hours of audio at one 80 ms frame each, turns that into a diagnosable error. Assisted-by: Claude Code:claude-opus-5[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(nemo-speech-cpp): implement TTS and streaming TTS The PCM callback is compiled once per process behind a sync.Once, not once per request and not once per load. purego.NewCallback writes into a fixed table of 2000 entries (purego/syscall_sysv.go) and never releases one, so a per-request callback panics the backend process on the 2001st synthesis, and a per-load one reaches the same ceiling on a server that swaps models. Synthesis is routed through that single callback plus a user_data id: engineMu is per-model, one process holds several models, so a single current-sink pointer would be overwritten by two TTS models synthesizing at once. Deviations from the brief, all verified against the real headers and proto: - TTS is TTS(*pb.TTSRequest) error and TTSStream is TTSStream(*pb.TTSRequest, chan []byte) error, per pkg/grpc/interface.go. The brief's context/pb.Result and server-stream forms do not implement the interface. The channel is closed on every path, including the family rejection, because pkg/grpc/server.go blocks on its drain goroutine and an unclosed channel hangs the RPC with the backend lock held. - The callback takes unsafe.Pointer, not uintptr. Converting a uintptr parameter back to a pointer is a checkptr violation that aborts under -race. - resolveSpeaker refuses to turn a negative number into a speaker index. -1 is the C API's "use the default" sentinel, so the brief's rule would have made a request naming an invalid voice synthesize in the default voice instead of being rejected. temperature and cfg_scale each write their override flag as well: magpietts/runtime.cpp reads the float only when the flag is set, so a temperature without it is silently discarded. Also folds in Task 8's review finding on asr.go: the six bare -1 sentinels in loadASR move to an asrDiarConfig builder reusing diarGeometryDefault, with specs. src/asr/c_api.cpp applies left_context_frames at >= 0, so a dropped sentinel pins the model geometry to 0 and no layout assertion can see it.

The pair comes from the source_language / target_language model options, with an optional leading [src->tgt] directive as the only per-request override, and PredictStream emits the whole translation as a single chunk because the C API has nothing finer to give it. Both RPCs wrap their body in withEngine so the family check and the C calls that trust the handle share one acquisition of engineMu. PredictStream closes its channel on every path, including the family rejection: this is the legacy streaming contract, and pkg/grpc/server.go blocks on a drain goroutine that only finishes when the channel closes, so leaving it open hangs the RPC rather than failing it. nmtTranslatorConfig is extracted so its four adjacent pointer fields can be asserted against distinct sentinels. Transposing two of them changes neither the struct size nor any field offset, so the layout assertions cannot see it. Also removes goString, which had no production caller: every string-returning symbol in abi.go is bound with a Go string return that purego converts itself.

The justification on the regex was also wrong and is corrected: pt-br and zh-cn are two segments and parse either way. It is the single-field form that needs the run. Renames the NMT handle to n.nmt so it stops sharing a name with the translator interface, following n.synth, which is shortened for the same reason. Assisted-by: Claude Code:claude-opus-5[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(nemo-speech-cpp): register the backend and give its specs a CI job Registers nemo-speech-cpp across every surface .agents/adding-backends.md requires, and adds the CI job its unit suite never had. backend/index.yaml gets the meta backend (capabilities map, no uri), a development meta and 12 image entries. No amd and no intel capability keys: upstream NeMo-Speech.cpp builds ggml with CUDA, Vulkan or Metal only, and SystemState.Capability falls back to "default", so those hosts get the CPU build rather than a tag that does not exist. The nvidia-cuda-* and nvidia-l4t-cuda-* keys are present because getSystemCapabilities() refines an NVIDIA host to them whenever the CUDA directory exists; without them every modern CUDA host and Jetson would miss the map and quietly run on CPU. .github/backend-matrix.yml gets 7 include rows and 1 includeDarwin row. No hipblas and no sycl rows, for the same upstream reason. cpu and vulkan are per-arch pairs sharing a tag-suffix so backend-merge-jobs builds a multi-arch manifest: an ARM host with no NVIDIA GPU reports "default" and the Jetson image does not cover it. The CI job is the substantive part. make test-extra is dead on master, because prepare-test-extra depends on a protogen-python target that does not exist and no workflow invokes it anyway, so the entry added earlier in this series ran nowhere. abi_test.go asserts the size and field offsets of every Go mirror struct against the C ABI it is dlopened into, and those assertions are the only defence against silent memory corruption after a purego symbol rename or an upstream header change. tests-nemo-speech-cpp in test-extra.yml now executes them on pull_request and on master, gated on the backend's own path filter. The recipe sets NEMO_SPEECH_REQUIRE_LIBS=1, so a missing library fails rather than skips. WITH_NORM=OFF skips the OpenFST leg and costs no coverage: nothing in the four C ABI headers is conditional on it, so the layouts are identical. Also registers the upstream pin with the bump bot, which the backend Makefile already claimed but was never wired up, and adds the BackendCapabilities entry so a hand-written model config gets a real usecase surface. PossibleUsecases is the union of the four families and DefaultUsecases is transcript alone, the audio-cpp pattern. No VoiceCloning key: MagpieTTS synthesizes from baked speaker ids, not a reference clip. No gallery entries: publishing converted GGUFs is a follow-up. ModelIdentity needs no work in this backend. main.go serves through grpc.StartServer, so every RPC lands on pkg/grpc's shared server wrapper first, and checkModelIdentity is the first statement of all seven handlers this backend implements. A second check inside NemoSpeech would be unreachable and would risk diverging from the cross-language sentinel the router matches on. AudioTranscriptionLive stays unguarded because TranscriptLiveRequest carries no ModelIdentity field at all, which is a proto-level gap affecting every backend and needs its own change.

A Jetson whose CUDA 13 runtime is present reports that capability and would have pulled an image with no libcudart.so.12 to dlopen, failing hard at load. That is worse than omitting the key: with no key Capability() falls back to "default" and the host gets a working CPU build. Fixed the way parakeet-cpp and moss-transcribe-cpp already do it, by shipping the second L4T image rather than dropping the key. Nothing prevents building it here: those peers use plain ubuntu:24.04 on ubuntu-24.04-arm with the same Dockerfile.golang as this backend's other rows, and every package in the nemo-speech-cpp apt gate exists on noble arm64. Adds the -nvidia-l4t-cuda-13-arm64-nemo-speech-cpp matrix row and its two index entries, repoints the key on both metas, and rewrites the capability-map comment, which had the reasoning backwards. Also adds the documentary inferBackendPath branch, matching all six sibling *-cpp Go backends. Behaviour is unchanged; the generic golang fallthrough already resolved this backend correctly. The previous commit message said "all seven handlers" of the shared gRPC wrapper. There are eight RPC entry points: seven are guarded by checkModelIdentity and AudioTranscriptionLive is the unguarded eighth, which that message already called out separately. Wording only.

The page covers the architecture-to-family table, every option key with a model YAML per family, the translation prefix directive, the acceleration matrix, and the four limitations this backend ships with: Linux-only inverse text normalization, suppressed interim streaming results, the library's default translation context and generation limits, and the absence of gallery entries. knownPrefOnlyBackends gains the backend so it appears in the /import-model dropdown. It stays preference-only and AutoDetect=false: general.architecture lives inside the GGUF where no remote-repo probe can read it, and a translation model carries an ordinary LLM architecture with no NeMo-specific marker.

The translation limits were described backwards. Input longer than the 1024-token context is rejected, not truncated: translator.cpp throws "nmt: prompt too long (N tokens) for context 1024", which reaches the caller as a failed request. What is silently cut is the output, by the max_new_tokens loop at 256. The bullet now separates the two and says which one fails quietly. The macOS gap covers TTS text normalization as well. Both directions sit behind the single NEMO_SPEECH_WITH_NORM flag, which the Makefile forces off on Darwin, so tn_dir is as inert there as itn_dir. Neither fails the load: both warn and carry on. pnc_model really is unaffected, since punctuation is compiled in unconditionally. The tn_dir row in the option reference gained the caveat the itn_dir row already had. The TTS conversion procedure produced a model that could not load. It converted MagpieTTS and stopped, leaving no NanoCodec, which the same page lists as required; following it gave "no NanoCodec GGUF found next to ...". Both halves are now there, each with the download that feeds it, so the block runs top to bottom on a clean machine. Also: any negative gpu value pins TTS to the CPU, not only -1, and FLAG_CHAT additionally surfaces the model in the web UI chat picker. Assisted-by: Claude Code:claude-opus-5[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(nemo-speech-cpp): map every C status, not just the NMT one INVALID_ARGUMENT was translated to codes.InvalidArgument at exactly one of sixteen C call sites. Everywhere else a non-zero status collapsed to codes.Internal, so the same backend answered an unsupported language pair with HTTP 400 and an unknown TTS voice, which is the same class of caller mistake against the same process, with HTTP 500. Status 4 is CANCELLED on the ASR and TTS surfaces and was reported as a backend failure rather than as the consumer having stopped listening. asr.h, tts.h and nmt.h each declare their own status enum and diar.h reuses the ASR one; the values they share agree, and the single divergence is that NMT declares no CANCELLED because nemo_speech_nmt_translate has no callback for a consumer to stop with. That is an absence, not a disagreement, so one table serves all three. status.go carries it, with the header line numbers and a note that a pin bump has to recheck it: purego binds by name and the status crosses as a bare int32, so nothing in the build or the linker can see a drift. New specs cover the whole enum, unknown values, and one real INVALID_ARGUMENT per family driven through the shared objects rather than through the Go mapping asserting against itself. Also add UsecaseChat to this backend's capability entry, which the docs already told operators to set for translation models. chat is a gallery filter key and completion is not, so GET /api/backends/usecases would have greyed the Chat filter out and hidden a Riva-Translate gallery entry from the one filter that fits it. The flag gates no endpoint; it makes the model eligible as the default chat model and puts it in the web UI chat picker, both of which Predict and PredictStream already serve.

Each was checked individually rather than blanket-suppressed, and each annotation states what makes that particular site safe. The G304 at audio.go is a false positive. The opened path is filepath.Join of a directory the function just created with os.MkdirTemp and a constant basename; the request-controlled path is the input to AudioToWav and never reaches the open. The twelve G103 sites are the package's three established shapes, and every one was verified against them: cstr and pinPtr take the address of something pinned on the line above and return it one-way (nothing in the package converts either result back, which is what keeps checkptr out of it under -race), and each *Create hands C a stack-local POD config whose uintptr members are cstr allocations or pinPtr addresses held by a pinner the loader unpins only after the call. The two slice-building sites are bounded by construction: DiarSegments is handed exactly len(buf) with the buffer sized under maxDiarSegments and a reported count larger than it rejected rather than sliced to, and the TTS callback copies out a slice whose length is the length the runtime declared for that buffer. Separately, sampleRateOf gets a real fix rather than an annotation. go-audio reads the WAV header's sample rate from an unsigned 32-bit field into an int, so a header claiming more than 2^31-1 passed the "> 0" test and then narrowed to a NEGATIVE rate, which the runtime would take as a resampling ratio. AudioToWav cannot produce one today, but that is a property of another package and this function exists precisely because the rate is read back rather than assumed, so the bound is enforced here and pinned by a spec. The four remaining integer narrowings are annotated with the bound that makes each safe: the WAV payload length is already checked against maxWAVDataBytes, the speaker count is bounded by maxDiarSegments, and the two segment ids are the proto's own int32 wire type.

Rather than hunt for a capable bash that the runner does not have, drop the step where it does nothing. ggml-patches/ is a CUDA series: every kernel it adds is under src/ggml-cuda/, and its whole footprint outside that directory is an op enum plus prototype in include/ggml.h, the constructor and a name-table entry in src/ggml.c, and two ggml-cpu lines that make the CUDA-only op report unsupported and abort. Nothing it touches is compiled into a Metal kernel or changes a CPU one. The project's own references to patch-only ggml symbols sit behind NEMO_SPEECH_FUSED_RELPOS_ATTN and NEMO_SPEECH_FASTCONFORMER_CUDA_FUSIONS, which cmake already forces OFF without GGML_CUDA, or behind NEMO_SPEECH_GGML_PATCHED itself, which guards a GGML_TENSOR_FLAG_Q8_PLANAR write that a non-CUDA buffer throws before reaching. So passing NEMO_SPEECH_GGML_PATCHED=OFF costs the Metal build nothing, and it is required once the series is skipped: that flag is what stops the ASR sources referencing a tensor flag stock ggml does not define. This is upstream's own Metal configuration. Its metal-* and vulkan-* CMake presets inherit the cpu-* ones, which set NEMO_SPEECH_GGML_PATCHED to OFF; docker/Dockerfile and scripts/windows/build.ps1 do the same for their non-CUDA targets. LocalAI's Makefile never passed the flag at all and so inherited the CUDA default everywhere. Linux is untouched and keeps applying the series, including its idempotency and its hard failure on a patch that does not apply. The gate is the same uname test the WITH_NORM block above already uses, and both branches keep the order-only clone prerequisite, which on a WITH_NORM=OFF tree is the only thing that pulls sources/ in.

This is ours, not an upstream regression: upstream defaults both NEMO_SPEECH_TTS_WITH_JA and NEMO_SPEECH_TTS_WITH_ZH to OFF and the OSS drop carries no CI at all, so that target is never built there. Upstream does already carry the equivalent workaround for MSVC's STL (_HAS_AUTO_PTR_ETC plus /FIfunctional) but has no libc++ branch. libc++ gates the two templates on _LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION, and has since LLVM 16, older than any clang Xcode still ships. The name is the whole problem: _LIBCPP_ENABLE_CXX17_REMOVED_BINDERS covers bind1st, bind2nd, ptr_fun and mem_fun and not unary_function or binary_function, and the umbrella _LIBCPP_ENABLE_CXX17_REMOVED_FEATURES no longer exists in libcxx at all. A wrong name preprocesses fine and fixes nothing. Applied through CMAKE_CXX_FLAGS rather than to the one target, because the tokenizer CMakeLists is upstream's and sources/ is a pinned checkout. Project-wide is also the safer scope: the macro decides whether libc++'s internal __binary_function alias resolves to std::binary_function or to __binary_function_keep_layout_base, a base class of std::less and friends, so defining it for a subset of translation units would give those class templates two spellings in one binary. Both bases are empty and, at C++17, carry identical members, so the define changes no layout and no ABI. Darwin only. On Linux the branch is unreachable and the macro is not a name libstdc++ knows, so it would be inert even if taken; a Linux configure with the flag forced on puts it on all 23 C++ TUs of nemo_speech_openjtalk_frontend including dictionary.cpp at -std=gnu++17, and on none of the 16 C TUs. Mandarin needs nothing: cppjieba v5.6.7 and limonp have no removed C++17 constructs left (limonp replaced std::not1 and std::bind2nd with lambdas) and cppjieba's own CI builds macos-14 and macos-latest at C++11 through C++20.

No C++ standard allows that, so the line is ill-formed everywhere; it survived because nothing instantiates FstImpl::operator= and gcc up to 13 only checks a template member's body when it is instantiated. gcc 14 resolves non-dependent operator expressions at template definition time, so it rejects the line in any translation unit that includes <fst/fst.h>. The CI diagnostic confirms the phase: it reads "In member function", not "In instantiation of", and carries no instantiation backtrace. That is why this surfaces only here. build_itn_deps.sh compiles OpenFST with gcc-12 and upstream's own images build the runtime with gcc-13, so neither compiler reaches the check; backend/Dockerfile.golang installs gcc-14 and promotes it with update-alternatives, and fst_normalizer.cpp is the one translation unit in this backend that includes OpenFST. Fix it in the installed ITN prefix, which is the only copy the cmake build compiles against, using the same .reset() spelling FstImpl::SetInputSymbols already uses for the identical operation. libfst.so is linked before this runs and cannot contain the function, since no compiler could ever have emitted it, so there is no ABI or ODR consequence. The rule is guarded on both sides so a pin bump to a fixed OpenFST fails loudly rather than silently no-opping. Verified with a real gcc 14.2: the CI error reproduces byte for byte from a file whose entire content is '#include <fst/fst.h>', and gcc 14 reports exactly two errors over the whole OpenFST include closure this backend uses, both of them these two lines. After the patch that closure compiles clean under gcc-14 with the target's own flags. The step is reachable only under WITH_NORM=ON, so 'make -n stage-libs WITH_NORM=OFF' mentions neither it nor the ITN build, and darwin, which defaults WITH_NORM to OFF, never evaluates it. Assisted-by: Claude Code:claude-opus-5[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(nemo-speech-cpp): install cmake 3.31 on bases that ship less than 3.26 The JetPack r36.4.0 row dies on the first line of NeMo-Speech.cpp's CMakeLists.txt: CMake Error at CMakeLists.txt:3 (cmake_minimum_required): -- Configuring incomplete, errors occurred! Upstream opens with cmake_minimum_required(VERSION 3.26). That base image is Ubuntu 22.04 jammy, whose apt cmake is 3.22.1, so configure aborts before it reads a single one of the backend's -D flags. Every other Linux row in this block is noble, which ships 3.28 and clears the bar, so the failure is one base image wide rather than a code problem. Everything before it on that row had already worked, including the OpenFST and Sparrowhawk ITN build. No other Go backend needs this. parakeet-cpp and moss-transcribe-cpp share the same JetPack base and both declare cmake_minimum_required(VERSION 3.18), and nothing in the repo installs a cmake newer than the distro's, so there is no existing pattern to reuse. Nothing depends on jammy's cmake staying 3.22 either: build_itn_deps.sh never invokes cmake at all, since OpenFST and Sparrowhawk are autotools builds. Kitware's release tarball rather than their APT repo or pip. The tarball is a pinned URL with a published checksum, so an upstream release cannot change what lands here. The APT repo does carry jammy arm64, but it serves a moving latest that today is CMake 4.4, and 4.x drops compatibility with cmake_minimum_required below 3.5, which vendored third_party subprojects still declare; pinning it there would mean tracking Kitware's Debian revision string instead of an upstream version. pip would drag a Python toolchain into a backend that has none. 3.31.12 is the last 3.x release, so it clears 3.26 while keeping the CMake 3 policy surface, and it stays close to the 3.28 the green noble rows already use. The binaries need only glibc 2.17 and carry no libstdc++ DT_NEEDED, well under jammy's 2.35. doc/, man/, ccmake and cmake-gui are not extracted; the final image is FROM scratch, but there is no reason to page 100 MB of Qt GUI and docs through the CI cache. Gated on the installed cmake actually being older than 3.26, so the rows that already build green keep configuring with exactly the cmake they use today, and folded into the existing ${BACKEND} block rather than added as a new instruction, so no other Go backend image gains a layer and nothing above the Vulkan SDK, CUDA, Go and protoc layers moves. The symlink lands in /usr/local/bin and shadows apt's cmake. Unlike the protoc shadowing that broke Sparrowhawk earlier in this series that is inert: protoc has to agree with the libprotobuf headers it generates against, whereas cmake links nothing into the product and has no ABI relationship with anything in the image, and it resolves the symlink back to /opt to find its own Modules/ tree, so a 3.31 binary can never read 3.22's modules. The version test avoids $(...) deliberately. BuildKit delivers a RUN heredoc through an outer shell with an unquoted delimiter, so a command substitution runs there, too early, in a container where the files it reads do not exist yet, and its empty output is pasted into the script; the first draft took the install branch on every row because of it. Verified by building the block against nvcr.io/nvidia/l4t-jetpack:r36.4.0 arm64 under qemu, the row's actual base image: cmake 3.22.1 detected, tarball checksum verified, 3.31.12 installed, and a cmake_minimum_required(VERSION 3.26) project configures with -G Ninja and builds, with CMAKE_ROOT resolving to /opt/cmake/share/cmake-3.31. Same on ubuntu:22.04 amd64 and arm64. ubuntu:24.04 skips the install, gains no /opt/cmake and still configures on /usr/share/cmake-3.28. The NeMo-Speech.cpp compile itself on JetPack CUDA 12 is not reproducible here and remains for CI.

mudler's LocalAI [bot]andEttore Di Giacinto	8845ccebf7	feat(gallery): default to index.localai.io with GitHub as a mirror (#11409) ... The primary is a caching mirror of the same two files, so an install resolves its gallery from infrastructure the project controls. The GitHub URI stays as a mirror, so behaviour is unchanged whenever the primary is unreachable. Docs and agent guides that either state the shipped defaults or hand out a copy-pasteable gallery list are updated to match, so following them no longer silently demotes an install off the new primary.

mudler's LocalAI [bot]andEttore Di Giacinto	a77780ad14	feat(gallery): fall back to mirrors and a cached index when the primary source fails (#11389) ... * feat(version): include OS and arch in the outbound User-Agent Registries and galleries already receive LocalAI/<version>; adding the platform follows ordinary client convention and discloses nothing a registry cannot infer from the manifest it is asked for. Updates the User-Agent note in docs/content/getting-started/models.md, which documented the old format. Assisted-by: Claude:claude-opus-5 [go vet] [go test] * feat(downloader): identify LocalAI on outbound requests pkg/oci has always sent a User-Agent; the downloader sent none, so gallery reads, model-file downloads, resume probes, content-length probes and the HuggingFace safety scan all went out as a bare Go HTTP client, unattributable to LocalAI by the hosts serving them. HuggingFaceScan moves off the client's Get shorthand to an explicit request for the same reason — the shorthand gives no place to hang a header. Extends the User-Agent note in docs/content/getting-started/models.md, which claimed the header was sent only to Ollama and OCI registries. Assisted-by: Claude:claude-opus-5 [go vet] [go test] * feat(gallery): add a mirrors list to gallery configuration Mirrors are an availability fallback, tried in order only after the primary URL fails. omitempty keeps existing configurations byte-identical. The slice makes config.Gallery non-comparable with ==, which broke the two slices.Equal callers in the runtime settings registry. Replace them with an explicit Gallery.Equal / GalleriesEqual so a gallery list that differs from the baseline only by its mirrors still counts as env/CLI-set. Equal compares the Verification block by value; == compared it by pointer identity, which called two structurally identical policies different. Assisted-by: Claude:claude-opus-5 [go vet] [go test] * fix(downloader): treat an HTTP error status as a failed read ReadWithCallback handed the response body to its callback whatever the status was, so a 404 page or a 502 from a CDN arrived as if it were a gallery index or a model config: it parsed to nothing, got cached for an hour, and no caller could tell the source had been down. DownloadFile has always checked the status; this path never did. Mirror fallback depends on it — a source that answers with an error page has to count as unreachable, or the next candidate is never tried. Assisted-by: Claude:claude-opus-5 [go vet] [go test] * feat(gallery): fall back to mirrors when the primary source fails Candidates are tried primary-first with a bounded timeout each, and a source that just failed is skipped for a cooldown so a dead host is not re-dialled on every listing. When every candidate is in cooldown they are all tried anyway: refusing to serve a gallery we might be able to reach is worse than one slow request. The one-hour index cache is untouched and stays keyed on the gallery's own identity, so a mirror-served fetch fills the entry the primary would have. No SSRF validation is applied to the candidates. validateGalleryConfigURL guards GetGalleryConfigFromURL because that URL arrives in a request body; mirrors come from the operator's gallery configuration, the same place the primary has always come from, and the index fetch has never validated the primary. Validating mirrors while the primary goes unchecked would buy nothing and would break the deployment mirrors exist for — an index served from a host on the LAN. Assisted-by: Claude:claude-opus-5 [go vet] [go test] * fix(gallery): loosen the mirror fetch timeout and stop blaming the caller The downloader only ever bounded response headers, never the body, so the per-attempt deadline added with mirror fallback was the first whole-transfer timeout this path has had. At 30s the default 2.2 MB index demanded ~75 KB/s sustained: a rural-DSL, mobile or satellite user who used to wait 60s and succeed would now fail, and then eat a 10-minute cooldown on a source that was perfectly healthy. Raised to 120s (~19 KB/s), which no link that could go on to download a model will miss, and made it a var so a test can shorten it and prove a hanging candidate is actually abandoned. Caller cancellation is no longer recorded as a failure of the source. Unreachable today since getGalleryElements passes context.Background(), but once a request context is wired through, a browser disconnect would have blackholed every candidate for ten minutes over something the sources had no part in. Also document that mirrors do not cover a .ref gallery URL: the reference is resolved before mirrors are considered, so a .ref that cannot be fetched fails the gallery outright. Routing .ref resolution through the candidate list needs a per-candidate resolve-and-fetch and a decision about cache identity, which is more than this change should carry. Assisted-by: Claude:claude-opus-5 [go vet] [go test] * feat(gallery): serve the last known good index when everything is offline A successful fetch is cached alongside the models directory and served when no source is reachable, so an offline or airgapped machine can still list its gallery. Entries may be stale in that state, and the fallback is logged. The copy is deliberately kept out of the models directory, where a <name>.yaml file is read as an installed model's configuration, and is named after a digest of the gallery URL so the model and backend galleries cannot collide. Writing it is best effort: a read-only or full disk must not fail a fetch that otherwise succeeded. Also corrects the mirror scheme list in the docs: the HuggingFace prefixes are huggingface://, hf:// and hf.co/, not huggingface:. Assisted-by: Claude:claude-opus-5 [go vet] [go test] * fix(gallery): only cache a response that is really a gallery index The last known good copy was written on any 2xx, before anything looked at the bytes: the parse only happens later, in getGalleryElements. A captive portal, a corporate proxy or a CDN error page all answer HTTP 200 with HTML, so any of them could overwrite a good copy. The listing fails then and there, and the next offline start — the one case this cache exists for — serves the interception page instead of the gallery it already had. Probe the body before persisting it: unmarshal into a []any and keep the older copy unless the result is a non-empty sequence. An empty document is rejected too. It parses fine, so a parse-only check would still let a blank response replace a populated index with one that lists nothing, which from the user's side is the same outage; and an empty index is worth nothing offline, so there is no case where caching it beats keeping what came before. The live body is still returned to the caller — the probe gates persistence only, and getGalleryElements remains the thing that reports a real parse failure. Also in this pass: - The empty-basePath guard only caught exact "". galleryCachePath(".") and galleryCachePath("models") still resolved the cache sibling against the process working directory, which is what the guard was written to prevent. Reject any non-absolute base. - The docs claimed the offline cache "applies to every gallery, with or without mirrors". Not true for a .ref URL: the reference is resolved before the cache is consulted, so a .ref gallery fails offline even after a successful earlier fetch, and the cache file it writes can never be read. Extend the .ref warning and qualify the sentence. - pkg/oci's UserAgent comment never mentioned the platform component added earlier on this branch. - resetGalleryFailures and expireGalleryFailure had no non-test callers; move them into the test file. - The all-candidates-failed error reported len(attempt), so a three mirror gallery with two sources in cooldown said "all 1 source(s) failed" — which reads as a misconfiguration. Report how many were configured and how many were skipped. - Give the package's tests their own TMPDIR. The cache is a sibling of the models directory, which is right in production, but specs that build a models directory directly under /tmp made the sibling resolve to /tmp/cache and left it behind after every run. Assisted-by: Claude:claude-opus-5 [go vet] [go test] * fix(gallery): convert the new tests to Ginkgo and clear the lint gate .agents/coding-style.md requires Ginkgo v2 + Gomega for every Go test and has forbidigo enforce it; the stdlib-style tests still in the tree are tech debt, not a pattern. Every test file this branch added was written in the forbidden style, which is what turned CI red. Convert all five of them. internal had no suite bootstrap, so add one; core/config, core/gallery and pkg/downloader already have theirs and are reused, so no package mixes styles. pkg/downloader/useragent_test.go and read_status_test.go were not in CI's forbidigo list but used the same forbidden calls, so they are converted too. The one conversion with a trap in it is core/gallery. Go's t.TempDir() yields $TMPDIR/<TestName>NNNN/001, so the gallery cache — a sibling of the models directory — was isolated per test. GinkgoT().TempDir() yields a flat $TMPDIR/ginkgoNNNN, which would put every spec's cache in one shared directory and break the specs that count files in it. tempModelsDir() restores the original isolation. Also make the deliberate cleanup-path ignores explicit with `_ =`, drop the gallery cache directory to 0750 (nothing outside the server's own user and group reads it), and justify the cache read with a #nosec G304 comment in the form already used elsewhere in the tree: the path is a hex sha256 under a fixed directory with a non-absolute base already rejected, so no caller-supplied text reaches it. Re-ran the mutations these specs were verified against — dropping the platform suffix from UserAgent, making Gallery.Equal ignore Mirrors and ignore Name, removing persistGalleryIndex's validity probe, removing the !filepath.IsAbs guard, not skipping a cooled-down candidate, and dropping the per-attempt timeout. All seven still fail the converted specs.

mudler's LocalAI [bot]andEttore Di Giacinto	ea438cdeaf	feat(vllm-cpp): wire the full engine config surface through engine_args (#11159) ... The backend could configure four of the engine's knobs (block size, KV block count, max sequence length, max concurrent sequences) out of a config surface that is considerably larger. Speculative decoding, prefix caching, the chunked-prefill token budget, the scheduling policy and the external KV connector were reachable from vllm.cpp's own HTTP server and from nothing LocalAI could write in a model config. Config now goes through `engine_args:`, the same map the vLLM and SGLang backends take, with keys spelled as vLLM's own CLI flags so a speculative_config or kv_transfer_config block written for vLLM works verbatim. The legacy `options:` list keeps working and reads every key too; engine_args wins where both set one. Unknown keys are logged and ignored rather than fatal: the field is shared with the other engines, so a config carrying their knobs must not take the model down. Two details worth knowing: `enable_prefix_caching: false` maps to the ABI tri-state force-OFF (2), not 0. 0 means "let the model capability decide" and dense architectures default the cache on, so collapsing the two would silently enable it against an explicit false. enable_jump_forward (ABI v10) shares the encoding, deferring to VT_ENABLE_JUMP_FORWARD instead of to the model. The importer probes config.json on a vllm-cpp import and writes speculative_config: {method: mtp} when the checkpoint declares an MTP head, the safetensors analogue of the llama-cpp importer's GGUF probe. DFlash draft repos are refused with a warning instead, since a drafter cannot serve alone and the pairing is not derivable from either repo. The draft path is resolved against LocalAI's model directory, because the engine only looks in a directory holding config.json or in the HF cache and never downloads: the repo-id spelling the vLLM docs teach used to die deep in the load with "draft checkpoint not found". docs/content/features/text-generation.md gains a vllm.cpp section covering the engine_args table, all three speculative methods, LMCache and the legacy list. The backend had no documentation page before. This replaces a branch that had gone stale behind master and carried its own route to ABI v10, which #11386 has since landed in minimal form. Rebased onto that as a single commit rather than replaying the intermediate steps, whose ABI v9 mirrors no longer make sense against master's pin. The Darwin build fixes for Apple Clang's gnu-folding-constant diagnostic on C++, Objective-C and Objective-C++, originally authored by localai-org-maint-bot, are folded in here. Verified: `make abi-check` agrees at v10; unit specs, core/config and core/gallery/importers green; and the full e2e passes in 1330s against a CPU libvllm.so reporting ABI v10 with Qwen_Qwen3.5-0.8B-Q4_K_M.gguf (load, blocking completion, streaming, chat and tool calls).

Ettore Di Giacinto	6bdb04ab5d	docs: point the News page at the blog instead of a stale highlights list ... The News page kept a hand-maintained "Highlights" list that had drifted: it was missing all of 2025, duplicated the README's own news list, and linked /features/middleware/ for a page that lives at operations/. Both of its jobs already have owners. website/content/blog/ carries the release write-ups and engineering notes, and GitHub Releases carries the full changelog. Replace the list with a pointer at those two, so there is one place to update instead of three. The page keeps its url and front matter, so /docs/basics/news/ and the root /basics/news/ redirect that .github/ci/gen-redirects.sh generates both keep resolving. Also drop the two contributor instructions in .agents that told authors to add a whats-new.md bullet per feature: announcing a capability is the release blog post's job, per .agents/preparing-a-release.md.

mudler's LocalAI [bot]andEttore Di Giacinto	58ea2f5d79	feat(ui): give Operate and Studio a front door, and fix two layout regressions (#11305) ... * feat(ui): give Operate a front door and fold six rail groups into four Opening Operate ran firstVisiblePath() and landed on Backends, because Backends happens to be written first in operateConsole.groups. The section that should answer "is anything wrong" opened on a package manager, and nothing was reported until you visited it. Adds /app/operate. Its one irreplaceable block is "Needs attention", which is empty when nothing is wrong and says so in a line rather than rendering a reassuring green panel. It collects stale backends, failed operations and unhealthy nodes. Everything else on the page is a summary you could already assemble by visiting four others. The rail regroups from six headings to four: Inference and Activity were both "the runtime right now", Access and System were both administration. No destination is removed and no gate changes, so isConsoleItemVisible and consolePaths are untouched. Overview leads the first group, which is what makes firstVisiblePath() return it without knowing it exists. Rail entries now carry a signal beside the label. This does not replace the sidebar badge and is not built as if it does: the badge stays on the always-visible sidebar entry for the reason recorded in Sidebar.jsx, that the rail exists only on Operate routes and can be collapsed. The signals are orientation while inside Operate, so they are aria-hidden and nothing urgent depends on them alone. OperateSummaryContext polls once for the whole console, following OperationsContext, which exists because per-consumer setInterval against one endpoint was the defect it fixed. It is mounted by ConsoleLayout for the Operate console only, so "poll only while in Operate" needs no route check. Built on usePolling, so it pauses on a hidden tab. Operations are read from OperationsContext rather than polled a second time, and each source degrades to no-signal on its own so one dead endpoint cannot blank the rest. It reads the cached GET /api/backends/upgrades and never the POST that forces a real registry check. Traces and Usage get no signal yet: /api/traces returns the list, so a count would mean fetching every trace to render one number. A counts endpoint is the honest fix and is scoped separately. Full e2e suite green (369 passed, 4 skipped), including a render-smoke entry for the new route. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude Code:claude-opus-5[1m] [Read] [Edit] [Bash] * feat(ui): open Studio on what this machine can actually make Studio was a tab strip over six generators that opened on Images, which was never a decision, only the first entry in BASE_TABS. Nothing said which modalities this installation could run, so the way to learn that video had no model was to pick the tab and find an empty select. Adds an overview tab and makes it the fallback. Explicit tabs still win, so existing deep links keep working; anything unrecognised or gated now lands on the overview rather than Images. Each tab carries a dot: filled when an installed model advertises that modality, hollow when nothing serves it. That is the feature in one detail, turning the strip from navigation into a report of what the machine can do before anything is clicked. The dot is aria-hidden because the overview states the same facts in words and the dots change as models load. Two kinds of unavailable, which had to stop looking alike: - switched off, via a permission: no tab and no lane, unchanged - available with no model: a lane, and a route to installing one Studio now owns one MODALITIES table so the tab strip and the overview cannot disagree about what exists, and calls useModels() once, unfiltered, grouping in the browser. useModels(capability) fetches the whole list and filters locally, so a hook per modality would have been six identical requests to /api/models/capabilities on every mount. There is a test for that. Recent outputs read every localStorage store through a new readAllMediaHistory(), which avoids mounting five hooks that carry save timers the overview has no use for. 3D is read separately through use3DHistory rather than folded in: its entries are GLB blobs in IndexedDB, so they cannot come from the same synchronous read. Typical cost is the median of this machine's own history, not a guess, and renders as a dash when there is nothing to go on.

The stat cards were being laid out by the wrong rule at every width. Two different components both claimed `.stat-grid`: the dashboard card strip that holds .stat-card children, and the detail-pane StatGrid the split views introduced further down App.css. Being later, the second won every shared property, so the cards got its 120px columns and its 1px hairline gap in place of their own 180px columns and spacing-md. Four cards were packed onto a row that fits two, labels wrapped to three lines and clipped, and the icon crowded the value. Renamed the strip to `.stat-cards`, after the children it actually holds, which also removes the mismatch of a `.stat-grid` container full of `.stat-card`s. The split-view component keeps `.stat-grid` and its BEM parts. The expanded console rail had no bounded height. Thirteen destinations stacked in one column is taller than a phone, so opening the menu pushed the page's own heading past the fold: the menu replaced the page rather than annotating it. Capped at 55vh with internal scrolling below 768px, so the content behind stays reachable. Both are asserted on behaviour rather than markup: no stat-card label may be clipped, the card gap must not be the detail pane's hairline, and expanding the rail must leave the page heading on screen.

Eyebrows go mint. Dividers become an opaque #29384a hairline rather than alpha over a varying surface, which is what makes stacked surfaces read crisply on the site. Light is derived, not inverted. The site ships one theme and never had to answer this, but the app does: blue darkens to #2f62d8, mint to #0d8b60 and amber to #8a5d0b, all clearing 4.5:1 on a cool paper ground, where the dark-mode values sit near 2:1. Same three roles, different values. Three files restate the palette because CSS variables cannot reach them: cmTheme.js (the whole CodeMirror theme), VoiceVisualizer and WaveformPlayer (canvas). Left alone they would have quietly kept the app half-Nord. The `.lane` primitive replaces the near-identical row CSS that OperateOverview and StudioOverview had each written: a full-bleed row on a hairline that insets on hover, with no card and no shadow. Callers supply only the column template. Both pages now use it, along with `.lane-head` for section rhythm and a `.page-pad` container for top-level pages outside a console shell — without which Studio sat flush against the sidebar with its eyebrow clipped. Studio's tab strip wraps rather than running off the edge at narrow widths. Full e2e suite: 386 passed, 4 skipped.

It now reports figures: how many models are resident, how many nodes are healthy, what share of memory is in use, set in tabular monospace so the digits line up. A chip answers whether; a figure answers how much, which is what someone opening the page at a glance is after. Resident models move from status chips to lanes, with the id set in a new `.lane__name--id` because an id is something you might type or paste and the UI face makes it read as a label. /api/system-information carries only the id, so there is deliberately no backend or memory column: inventing one would mean a server change this does not make. The footer was three centred rows and cost the bottom sixth of every page for chrome. It is one line now, version left and links right, wrapping to centred when the viewport is too narrow to hold both. Every link it had, it keeps. Full e2e suite: 392 passed, 4 skipped.

The website does exactly this, but a button label in an app is not large text, so the label goes to dark ink at 5.88:1. Light mode keeps white, which is 5.44:1 on its darker blue. - Light-mode success was 4.08:1 on paper, not the 4.5 claimed. Darkened to #0a734f, 5.56:1. - Nord red was already 4.28:1 on raised surfaces, a pre-existing miss carried over unexamined. Lifted to #c96f78, 5.02:1. Lanes gain the two states they were missing: a 44px target on coarse pointers, matching what EntityRail already does so the two list idioms feel the same under a thumb, and a reduced-motion variant that keeps the background feedback while dropping the hover inset, which is a position change. The Operate summary no longer asks for /api/nodes on a single-node install. The cluster API answers 503 when distributed mode is off, so it was a guaranteed miss every fifteen seconds; it is now gated on useDistributedMode, the same condition the rail already uses for the Nodes entry.

But every <section> makes its lane-head a first child, so the reset applied to all of them and the gap between blocks vanished: "Sections" sat flush against the attention row above it. The header supplies its own bottom margin, so a uniform top margin is correct everywhere.

The OS setting no longer selects light on first load. The toggle still does, and a stored choice wins forever after, which the tests assert both ways.

Adds GET /api/traces/summary: totals, failures, p95 and a bucketed series for sparklines, over a window that defaults to 24 hours and is capped at a week. Deliberate calls, each with a spec: - A 4xx is the caller getting it wrong, not the installation being unhealthy, so only 5xx and transport errors count as failures. - p95 is a nearest-rank percentile rather than the slowest request, which is what a max would report and what makes latency panels lie. - Buckets are oldest-first so a sparkline reads left to right, and the slice is never nil: nil serialises as null and breaks .map() on the other side, which is a silent runtime error rather than an empty chart. - Exchanges outside the window are not counted at all. The route is registered before /api/traces/:id so "summary" is not captured as a trace ID. On the client, Traces and Usage gain the rail signals they were shipped without, the Observability section summary now states counts instead of listing its destinations, and an installation that has served nothing says so rather than showing three zeroes dressed as telemetry. Sparkline is a bare stroke with an emphasised endpoint and no axes: the figure above it already states the value, so its only job is the shape. Go: 185 middleware specs pass.

But an over-limit build still installs — #11288 keeps a test on exactly that — so red overstates what is happening. A model that fits at 32k and not 64k is a trade-off, not a fault. Over-limit bars and the limit line now use the warning tone, which is the constraint colour used everywhere else in this branch: know what you are doing, not you may not.

The overview's headline figures, attention rows and section lanes stagger in, as do Studio's modality lanes and recent outputs, so a page assembles in the order it is read instead of appearing all at once. Two additions beyond stagger. Rail signals transition on opacity when a poll lands, so a number changing reads as an update rather than a jump cut, and it stays on the compositor so it cannot reflow the rail. The attention block animates its left edge in — the one thing on the page that should announce itself, and on the border rather than the text so nothing moves under a reader.

The control column stops being a shadowed card of boxed groups and becomes a hairline field stack — the panel is the page's left half, not an object floating on it — with uppercase micro-labels matching the eyebrow treatment used elsewhere. Because .media-controls is shared, Images, Video, 3D, Speech, Sound and Audio FX all move together. RequestPanel shows the request the form actually built, with a copy-as-curl. LocalAI is API-first and Studio is the best place in the app to teach its own endpoints: the form stops being a black box, and a result worth keeping can be reproduced from a shell without reverse-engineering which fields the page sent. It records what was sent rather than what the form currently holds, and renders nothing until a request has been made — a panel describing a request nobody made is a tutorial, not a record.

The user turn keeps a left edge in the action tone so the two are still told apart at a glance, without a fill or a corner radius. The avatars go: the accent and the label carry the speaker, so the glyph was decoration once neither side had a bubble.

Swagger UI has no theming hook, so rather than fork it we serve our own index ahead of the library's wildcard and restate the palette over its stylesheet. The library's own bundle and assets are still what load, so a swagger-ui upgrade cannot silently break the page — this is a skin, not a fork. Two things needed real care. Swagger tints the entire operation row per method via .opblock.opblock-post and friends, so the palette had to match that specificity rather than reach for !important; the method now lives on one edge instead of washing across the row, because a page where every row is a status colour has no status colour left. And the filled method chip put white on pale green, which was the least readable thing on the page — it is an outlined mono chip now, carrying the method in its border and text. Palette values are copied from theme.css rather than referenced: this page is served by Go and never sees the app's CSS. The comment says so, and says to keep them in step.

Every sweep I ran for this was horizontal, which is why it kept coming back clean. The page now scrolls inside the pinned shell. The pane keeps its own scroller: letting it grow instead pushes the document taller and stretches the rail to match, which is the regression e2e/discover-height.spec.js exists to catch, and which the first version of this fix duly caused. **The Agents header controls were unstyled** — "Create Agent" was rendering with the browser's default chrome. The markup had been mangled at some point: six unrelated classes merged into one string on the link, and the label and button left with none at all and empty icons. Repaired, with the inline flex replaced by a shared .header-actions class. **Page titles take the editorial scale from the site**: larger, tracked at -0.04em, on a line height near 1, so a two-word title reads as a statement rather than a label. The typeface is unchanged — DESIGN.md keeps the existing type system — so the whole difference is scale, tracking and leading, which is where the site gets its voice from. This was the biggest reason the running app still did not look like the mocks. Full e2e suite: 404 passed, 4 skipped.

mudler's LocalAI [bot]andEttore Di Giacinto	1aa97381f3	perf(gallery): warm variant descriptions alongside VRAM estimates (#11297) ... Follow-up to #11288, which warmed the VRAM estimate caches at startup and left the variant picker paying its own way. Describing an entry's variants probes the weight files of every build it offers, so the first time a model is opened costs 1.2-1.9s against a cold cache. That is the same cost as an estimate wearing a different hat, and it lands in the same caches underneath, so it belongs in the same pass rather than in a second mechanism. The warm-up now describes variants for the entries it walks. Entries that declare none cost nothing: the call is gated on HasVariants rather than attempted and discarded. The host resolve env is derived once for the run, since it describes the machine rather than the entry. Failure handling matches the estimate half. An entry whose variants cannot be described is logged at debug and skipped, and the estimate for that same entry is unaffected, because neither half is allowed to fail the other. Measured against a live instance with 1,595 models, first ever call to /api/models/variants/:id after a cold boot: before 1.2-1.9s after 2ms The warm-up's own cost barely moves: 3m0s to 3m19s for 300 entries, of which 40 declared variants. It stays bounded by the same knobs, and LOCALAI_VRAM_WARM_LIMIT=0 still turns the whole thing off.

A bare "Models" was the obvious fix but it collides with the installed-models view under Host, which is a different page for a different job. "Discover" keeps the rhythm and says what the page is for. The icon moves from a download arrow to a compass for the same reason: the page is browsed before it is installed from. Translated in all seven locales rather than left to fall back, so a locale switch does not leave the entry in English. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * feat(ui): replace the gallery table with a rail and a detail pane The eight-column table was not the real problem; the click-to-expand row underneath it was. Variants, files and a VRAM estimate never fitted inside a <tr>, so they were pushed into a drawer that could hold one model at a time, could not be linked to, and had no room to say anything useful. The gallery is now a rail to scan and a pane that answers. The pane has two states and no third: with nothing selected it is the discovery page, and with a model selected it is that model's detail. Selection lives in the URL, so a model is linkable and Back steps out of the detail instead of off the page. The rail groups by capability while browsing and flattens to results the moment a term is typed. That is a rule rather than a toggle: once someone has said what they are looking for, the buckets are between them and the answer, and making the user choose would be handing them our problem. The detail pane plots VRAM against context length with the host's own limit drawn across it. This is new information, not a restyle. A single number invites "so will it run?", and the honest answer is usually "yes, up to a 32k context", which is a shape rather than a number. The estimates were already fetched for every context size, so it costs no new request. Backends that take no context length say so instead of being given a meaningless chart, and a host with no GPU gets no chart at all rather than bars with nothing to compare against. The split-button variant menu goes with the actions column. The pane lists every build with its backend, quantization, size, fit and a details disclosure, each installable, which is what the dropdown was a cramped substitute for. Its tests move onto that list; the three contracts it alone carried (fetch-once caching, the loading state, an unfit build staying installable) are backfilled against the pane. RecommendedModels moves inside the pane, where it has the width to argue for a model instead of listing one, and keeps its own dismissal and collapse. Rail entries carry no description. Two lines is the budget and the second is better spent on whether the thing will run; the stripped-Markdown contract moves to the pane's lede, tooltip included. e2e: 123 passing across models-gallery, navigation, recommended-panel, model-artifact-operation, operations-strip and page-render-smoke. Inline styles in Models.jsx drop from 82 to 41.

Backends and Host have the same defect and want the same shape, so leaving them there guarantees three rails that drift. SplitView, EntityRail, DetailHeader and StatGrid now live under components/split/. EntityRail is deliberately data-driven: a surface maps its own entity onto { id, name, icon, meta, stripe, groupId } and keeps its vocabulary to itself, which is what stops the rail learning about models, backends and loaded state all at once. The CSS moves with it. What was .discover__rail is .entity-rail, .discover__ pane is .split-view__pane and so on, because a class named after one page is a lie on the next two. Only what is genuinely Discover's stays behind the old prefix: the shelves, the hero and the VRAM-by-context chart. Two additions the shared rail needs and Discover did not: a state stripe, for surfaces read by condition before they are read by name, and an empty label. Discover passes neither. No behaviour change. e2e 100 passing across models-gallery, navigation and models-recommended-panel. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * feat(ui): put the backend gallery on the split view Same defect as the model gallery, so the same shape: a seven-column table over a click-to-expand row that was the only place the repository, licence, tags and links could go. The rail groups backends by the use case they serve, sharing Discover's taxonomy on purpose: a backend is the runtime a use case needs, so "vision" ought to mean the same thing one level down. It flattens on a query for the same reason it does on Discover. The zero state is the one real departure. A backend's fitness is not free memory, it is the accelerator and platform it was built for, so the pane leads with what this host is, then what is not installed yet, then whether anything installed has gone stale. The table listed 37 runtimes and left "which of these can even run here" entirely to the reader. Distribution moves into the pane, which is the one thing a row could never carry: which nodes hold a copy and which do not, with the install-on-more control next to it rather than squeezed against a chip. The distributed and target-node action logic is unchanged, including the guard that keeps a hardware-specific build off the fan-out path. The split-button popover loses its per-row anchoring because there are no rows; one pane, one anchor. Selection lives in ?backend=, preserving the ?target= scope rather than clobbering it. e2e: 139 passing across models-gallery, navigation, backends-management, models-recommended-panel, nodes-per-node-backend-actions, page-render-smoke, operations-strip and model-artifact-operation. The backends spec gains six split-view tests; its three description-cell tests move onto the pane lede.

Both tabs had the same click-to-expand row, so the shell transfers; what does not transfer is the zero state, because there is nothing to discover in your own inventory. With nothing selected the pane reports what is happening: how many models are loaded, what failed, what has an update, and which models are holding VRAM right now. Every number was already on the page. None of them had been assembled into one statement, so "what is going on" was a question the tabs could not answer however long you looked at them. The rail buckets by state rather than capability - Running, Idle, Disabled for models; Update available, Installed for backends - which is the opposite of the galleries and deliberately so: nobody opens Host wondering which of their models does vision. Entries carry a state stripe for the same reason. Load and Stop are promoted out of the kebab, because that is what an operator came for; the rest stays behind the menu rather than diluting it. Adopted, pinned and alias badges follow the model into the pane: they are facts about the thing, not about its state, and the rail line is spent on state. Deliberately NOT done: folding the two tabs into one rail, as the mock had it. It costs five URL parameters, the manage-tab localStorage key and the stat-card shortcuts, all of which are live deep-links today. The tabs stay as the group selector; merging them is a follow-up with its own migration. e2e: full suite 355 passing. New host-split-view spec; alias-template, manage-logs-link, manage-action-menu-position and model-editor-back-nav move off `.table` and the row kebab onto the rail and the pane.

The rail was not a listbox. ARIA lets a listbox contain options and groups, and nothing else, but each group's collapse control is a button that has to sit inside the scroller with the entries it folds. It is now a labelled group of buttons, which is the honest description; selection is announced with aria-current and the arrow keys are unaffected. Every entry was its own tab stop, so tabbing past a forty-entry rail to reach the pane took forty keystrokes. Roving tabindex makes the rail one stop, and arrowing now moves focus with the selection instead of leaving it behind on an entry Tab can no longer reach. The rail rounds its corners with overflow:hidden, which was clipping the focus ring off the first and last entries entirely. Inset outlines fix it. A 30px row is fine under a mouse and too small under a thumb, so coarse pointers get a 44px target without costing density on a desktop. One slot said three different things: "9 models loaded" on Discover, "12 loaded" on Backends, "3 of 9" on Host. All three lists are a page of a larger set, so all three now say so the same way. Also removed: an emptyLabel prop on EntityRail that nothing passed, its dead CSS rule, and MODELS_COLSPAN and ResourceRowDesc, which died with the tables. e2e: full suite 355 passing. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * fix(ui): correct three defects only a real gallery exposed Running the branch against a live instance with 1,595 models and 1,017 backends, rather than against mocked fixtures, surfaced three things the e2e suite could not. Grouping did nothing. The rails matched on the use-case keys the filter chips send (`chat`, `tts`, `transcript`), but those are a server-side vocabulary the handler maps onto entries. What entries actually carry is free-form and inconsistent: models come back tagged `llm`, `gguf`, `vision`, `coding`, and backends `LLM`, `text-to-text`, `audio-transcription`. Nothing matched, so every model landed in "Everything else" and the feature was decorative. Grouping now lives in utils/entityGroups.js, shared by both galleries, matching case-insensitively against the vocabulary the API really uses, with the entry's backend as a fallback signal - a backend named `whisper` is a speech backend whatever its tags say. Order is specific before general and that is load-bearing: a vision model is tagged `llm` too, so testing text first would swallow it. The zero state claimed GPU memory on a machine with no GPU. The resources endpoint reports system RAM in the same field when gpu_count is 0, so the hero read "84.4 GB of GPU memory" next to the recommendations panel correctly saying "No GPU detected". The number was never wrong, only its label; it now says system memory unless a GPU is actually present. The page title still said "Install Models" under a nav entry saying Discover. Also: the keyboard test named the model it expected to arrive at, which made it a hostage of the grouping table and broke the moment the buckets were fixed. It now asserts that the selection moves and returns. e2e: full suite 355 passing. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * fix(ui): the filters and the rail were fighting over the same job Four things you find odd on Discover, and they turn out to be one mistake seen from four sides. The rail grouped the current page. The listing is paginated at nine rows, so those bucket headers described nine entries out of 1,595, and turning a page reshuffled the sections under the reader. The structure was never stable because it was computed over the wrong set. The chips were redundant for the same reason, seen from the other side. They send tag= and filter all 1,595 server-side. The rail grouped nine of them client-side by the same axis. Two controls for one job, and the weaker one was the one this branch added, so it goes. Grouping stays only on Host, where the list is complete, local, and bucketed by state rather than capability. The search bar felt odd because it sat in a full-width band while the thing it narrowed was a 290px rail below and to the left. The whole band now lives in the rail column: search, backend, use cases, refinements, then the list it narrows. One column to say what you want, one to show what you got. Nineteen chips do not fit at that width, so they fold into a disclosure that states the selection. A disclosure and not a popover, deliberately: picking use cases is multi-select and interleaves with the backend select and the toggles below, and a popover dismisses itself the moment you touch either. The header held two counts and two buttons at arm's length from all of it. The counts were the third statement of the same number on one screen, after the rail's "9 of 1,247" and the pane's own headline, so they go. The buttons move into the pane's zero state, which is the surface that answers "what do I do here". Also: the two first-run empty states wore .loading-center, which is display:flex in the default row direction because it exists to centre one spinner. With four children that put the icon, the heading, the sentence and the buttons on a single line with no gap. They are now a proper full-height empty state. e2e: full suite 353 passing. Grouping tests are replaced by ones asserting the rail stays flat; chip tests open the disclosure first; two filter-layout tests that asserted the old three-band arrangement now assert the column. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * polish(ui): make Discover a full-height view, group the chips, name the refinements Four things, all of them the same complaint: the page read as a document with controls scattered on it rather than as one view. The header is fused. A title block with its own padding, a subtitle and two counts made the split view look like an attachment to a document that happened to sit below it. It is now a slim bar carrying the title, the count and the two page-level actions, and the split fills the rest of the window. Rail and pane scroll independently, so the filters and the pane's headline stay put while a long list moves under them. The chips group. Nineteen in a flat row is a lot to scan even behind a disclosure, and they already belong to the four families the rest of the UI speaks, so they are bucketed by those. "All" sits on its own above them without a heading, because it is a reset rather than a use case. The refinements stop looking dumped. When the band became a column they were three controls left where they landed; they now read as a named section with one control per row. The zero state suggests again. It had decayed into a "Browsing / 9 of 1,247 / select a model" line that restated the count for the third time on one screen. It now offers the four use cases as tiles that set the filter, which is the shelf idea from the mock without inventing curation or paying for a second fetch. Two bugs found by looking at it rather than at the tests: the disclosure was clamped to 190px, which cut it off partway through its third section so two of the five never appeared at all; and the creation actions rendered twice, once in the new bar and once in the pane hero a few pixels away. e2e: full suite 353 passing. The chip-row test now holds its contract across the per-family rows rather than a single one, and additionally asserts every family is present and non-empty. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * fix(ui): pin the split view's height so a long detail scrolls the pane Selecting a model with a long description grew the whole page and dragged the rail down with it, which is the opposite of what "full height" was supposed to buy. The flex chain was right and the ceiling was missing. .app-layout and .main-content are min-height:100dvh, which is a floor: flex distributes free space but nothing caps growth, so a pane taller than the viewport expanded the column, the document scrolled, and the rail stretched to match. height:100% on the pane then resolved against an auto-height parent and did nothing. The chat route already solves this by pinning .main-content to 100dvh. The same treatment now applies to any route containing a .page--app, selected with :has() so the shell does not have to learn which pages happen to be split views. Below the stacking breakpoint the pin is lifted, because two stacked halves in two short scrollers is worse than a page that scrolls. Measured on a live instance: document height stays at the viewport across selection (950px either side) and the pane overflows internally instead. Adds discover-height.spec.js, which asserts the page height and the rail height are unchanged by selection and that the pane is the thing that scrolls. The existing specs could not have caught this: they mock short descriptions, and the bug only appears when the pane has more content than the viewport holds. e2e: full suite 355 passing. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * feat(ui): give Backends and Host the full-height view, and fix the Update button Backends now matches Discover: the header fuses into a slim bar carrying the title, the count and the page-level actions, the filters move into the rail column where they narrow the rail and nothing else, and the split fills the window. Its seven chips fit at rail width, so unlike Discover's nineteen they need no disclosure. Host gets the bar and the height; its resource monitor, summary cards and tabs stay above the split, because those are read once while the rail and the pane are worked in. Two things the height change surfaced. The console layout is a flex row with align-items:flex-start, so its body sizes to content. Right for the pages it was built for, wrong for a split view, which needs a ceiling to scroll inside: without it the Backends rail ran past the viewport and over the footer. Pinned with :has() so only split-view routes are affected. The filters vanished when nothing matched. Both galleries swapped the whole shell for an empty state, which took the search box and the chips with it, so the page said "try adjusting your search or filters" while offering neither. The shell now stays and the empty state moves into the pane. Also fixes the Update control on Host, which had no className at all and rendered as bare text, next to a status span that had picked up btn classes and two copies of `fas` and so rendered as a button you cannot press. They have swapped appearances back. e2e: full suite 355 passing. The render-smoke selector learns .view-bar__title, since the pages it checks no longer all use PageHeader. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * fix(ui): keep the view mounted while searching, and bring rail grouping back Searching replaced the whole view with a loader. The search box lives in the rail column, so every debounced refetch unmounted the field being typed into and dropped its focus with it. The list, the filters and the pane went too. The shell now stays and the rail says it is busy: a sweep bar under its header and the stale list dimmed, so the eye knows the answer is being replaced without losing its place. A cold start still gets the skeleton, because there is nothing to keep. The condition for that is "nothing has loaded yet", not "the list is empty". Those differ exactly when someone is editing a query that matched nothing, and getting it wrong there would unmount the view on the keystroke after a no-results search - the worst possible moment. Grouping comes back on both galleries. It was removed because nine rows could not fill five buckets, so a page turn rebuilt the rail's whole structure. That was a symptom of the page size rather than of grouping: the rail now asks for 30 rows instead of 9 (Backends 60 instead of 21), which is enough for the sections to read as structure and turns five times fewer pages. The order of the sections is fixed, so what changes between pages is membership, not arrangement. Grouped while browsing, flat while searching, as before: once a term is typed the buckets stand between the reader and the answer. Also gives GalleryLoader a class and a testid instead of six inline style declarations on a bare div, which is why nothing could select it. e2e: full suite 359 passing, including a new spec asserting the search box keeps its focus and its value across a refetch, and that a cold start still shows the skeleton. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * perf(gallery): stop invalidating the VRAM estimate caches on every request Searching or turning a page felt slow. It was not the search and not the listing: /api/models answers in 3-9ms. It was the VRAM estimate, which the gallery asks for once per row, and which took ~2.3s every single time however often the same model was asked about. pkg/vram already caches what makes that expensive - the remote content-length probes, the GGUF metadata reads and the HF repo sizes. Those caches key on a gallery generation counter, and AvailableGalleryModelsCached triggered a background refresh on every call, with each refresh bumping the counter. One page view is one listing request plus thirty estimate requests, each of which re-read the gallery and started another refresh, so the generation moved constantly and every cache entry was stale before it could ever be read. The caches were dead in production. Three changes, each doing one thing: A refresh interval. The cached list is still served immediately; this only decides how often re-fetching from upstream is worth starting. Five minutes, as a package variable so tests can drive it without waiting. A generation bump only when the gallery actually changed. An unchanged gallery re-fetched on schedule must not throw away work that is still valid, which is the difference between an estimate costing nothing and costing a network round trip. A separate "loaded" flag. The cache engaged on `cached != nil`, so a gallery that legitimately holds nothing read as never-loaded and took the blocking path on every call, bumping the generation each time. Found by the test for the interval, which could not pass while this was true. Measured against a live instance with 1,595 models: one estimate, repeated 2.3s -> 2ms a page of 30, in parallel 10s -> 0.04s A first, genuinely unseen model still costs its remote probe. That is inherent; what changed is that it is now paid once per model per gallery version rather than once per request. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * perf(gallery): warm VRAM estimates at startup, and stop the UI waiting on them Two halves of the same complaint: the gallery stalls on VRAM estimation. Server side, the estimates are now warmed in the background at startup. Estimating an entry nobody has asked about costs a remote probe of its weight files, and the gallery needs one per row, so the first visitor was paying for the whole page. The warm-up walks the gallery in the order the UI lists it, so the first page is ready before anyone reaches it. It is bounded and it never blocks: 300 entries at 4 at a time by default, on its own goroutine, stopping with the server's context. Warming the whole gallery would be thousands of probes on every boot, which is rude to the upstream and slow to finish; warming nothing leaves the first page paying two seconds a row. Anything past the limit still warms itself on first view. LOCALAI_VRAM_WARM_LIMIT=0 turns it off for an air-gapped host, LOCALAI_VRAM_WARM_CONCURRENCY=1 slows it for a metered link. Client side, the page no longer waits on estimates it does not need yet. It fired one request per row at once; a browser allows about six connections per host, so thirty estimates took every slot and the request behind a click - the variant list, an install - queued behind work nobody asked for. That is the freeze: the list was already usable, and the UI was busy fetching sizes. Four at a time leaves room for the interactive request to overtake, and a row whose estimate is still in flight says "sizing…" rather than leaving a blank where a number will appear. buildEstimateInput moves to core/gallery as EstimateInput, since the handler and the warmer both need it. Measured against 1,595 models, from a cold boot: page 1, 30 estimates in parallel 10s -> 0.04s full warm-up (299 of 300 entries) 3m, in the background Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * chore: untrack data/.local_user_id and ignore the runtime data dir `local-ai run` writes its instance state under ./data when started from the repo root, which is exactly what a contributor testing a build does.

It requires cogito v0.11, so pull that bump forward on its own: minimal version selection would apply it to LocalAI anyway, and both repos use cogito and cogito/clients. Landing it separately keeps the harness change reviewable. nib itself is not pinned yet. Nothing in LocalAI imports it, and 'go mod tidy' runs as a goreleaser before-hook in CI, so an unimported require line does not survive. It lands with its first importer. No LocalAI call site needed a change. Both cogito.WithMaxAttempts callers guard the argument above zero, so v0.11's new clamp is unreachable, and LocalAI's Multimedia values implement only URL(), so v0.11's new TypedMultimedia routing treats them as images exactly as v0.10 did.

The normal error handler sends an OpenAI error envelope, which arrives as *openai.APIError; the opaque-errors handler replies with a bare status and no body, which arrives as *openai.RequestError. Classifying on only one of them misses half the cases, so the status is read from either. A cancelled probe is not reported as an unreachable server, because it learned nothing about the endpoint, and neither is a reply that could not be parsed, because something did answer. Both would otherwise send the user off to start a server that may already be running. The model list is returned verbatim and in server order. LocalAI lists whatever it finds in the models directory, including stray archives and dotfiles, and deciding which advertised ids are real belongs to whoever presents them.

One two-method interface that *os.Process already satisfies leaves nothing to swap and nothing to nil.

The REPL goes with it. Its model listing and its 401 classifier were duplicates of the ones Probe now owns, and the classifier was the version that misreads a bare 401 with no OpenAI error envelope, so keeping either would leave the package with two divergent answers to the same question. github.com/mudler/nib lands in go.mod in this commit rather than earlier: go mod tidy runs as a goreleaser before-hook on every PR, so a require line with no importer is stripped before it reaches CI.

The questions move onto one prompter that owns its buffered reader.

The budget is context.WithTimeout rather than a cancel plus a timer. Probe deliberately refuses to call an endpoint unreachable on a context.Canceled, since a caller who gave up learned nothing about the server, and only honours a deadline.

ModelRequest gains Notify for exactly this class of problem, one that is worth telling the user about but not worth failing over, and the chat wiring points it at the same writer the question was asked on.

Ctrl+C was already safe, but only incidentally, because the child shares this process' foreground process group. A signal handler rather than Pdeathsig on the child. Pdeathsig is Linux-only and, in Go, is delivered when the OS thread that forked exits rather than when the process does, so it can fire on a healthy parent. Setpgid would break the Ctrl+C that works today by taking the child out of the foreground group. SIGHUP joins SIGINT and SIGTERM: a terminal program whose terminal is gone has nobody left to talk to. The same context is what cancels the agent, which nib leaves to its embedder.

Every 'mcp ...' invocation counted as management, so 'local-ai chat mcp --stdio', which serves the agent over MCP and needs a model like any other session, was handed an empty one. And --init, whose shell snippet a user pastes into an rc file long before any server exists, went the other way: it demanded a running server to print a static string. The mcp split is asked of nib's own IsMCPManageSubcommand rather than restated here, so a verb added upstream cannot drift out of this list.

The refusal to render the full-screen interface into a pipe is the one they meet in practice: it names --cli, and burying that hides the fix. ExitCodeError says "already reported, exit with this status". main honours it and prints nothing more, so a piped or redirected chat still fails a script the way it should.

SIGHUP has no such backstop, and registering for it removed the default disposition that used to end the process outright, so kill -HUP left a live TUI with a cancelled context and the started server still running. runSession watches the context alongside the agent and stops the server the moment it is cancelled, so the guarantee no longer depends on what the agent does with cancellation. Stop is idempotent, so the deferred call stays correct and free. The doc comment on shutdownContext described the mechanism it was supposed to work by rather than the one that does. Corrected, bubbletea's handler included. ResolveModel now checks the chooser's answer against what it offered. The shipped chooser answers by list index and cannot be wrong, but ModelChooser is exported, the answer is persisted, and every later run starts against it, so the invariant belongs at the consumer. Assisted-by: Claude Code:claude-opus-5 [Bash] [Edit] [Write] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * chore(chat): bump nib to v0.5.1 v0.5.1 carries four fixes that matter to 'local-ai chat': - --init now names the embedder's command, so the emitted widget invokes 'local-ai chat' rather than a bare 'nib' the user does not have. - A piped CLI session that succeeds exits 0 instead of failing with EOF. - EOF at a tool-approval prompt denies the call rather than approving it, and the session exits 3 (app.ExitCodeApprovalNoInput) so a script can tell "answered" from "refused to act" without reading stdout. Read-only tools are unaffected and still run. ExitStatus already unwraps app.ExitError, so the code propagates with no change here. - RunTUI passes the context to bubbletea and gives up bubbletea's own signal handler, which makes shutdownContext the single owner of the signal and stops a SIGHUP leaving a wedged TUI behind. Verified against a live server on 127.0.0.1:8080: the three --init shells, a piped prompt exiting 0, a denied 'touch' that left no file and exited 3, a read-only 'ls' that still ran and exited 0, and a SIGHUP that unwound a TUI running under a pty. Two comment blocks in run.go described the old TUI behavior and are now wrong, so they are corrected in the same change. No behavior change: both shutdownContext and runSession are untouched, and stopping the server on cancellation is still worth keeping independent of how promptly nib unwinds. One known gap, not addressed here. The widget --init now emits runs 'output=$(local-ai chat --height 50%)', and runAgent injects Stdout unconditionally, so under $(...) nib refuses the TUI for a non-terminal stream. This is the cost the runAgent comment already anticipated, now that the snippets no longer hardcode standalone nib. Ctrl+Space should not be documented until that is decided. Assisted-by: Claude Code:claude-opus-5 [Bash] [Edit] [Write] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(chat): let nib own stdout, so the Ctrl+Space widget works The widget 'local-ai chat --init' emits runs 'output=$(local-ai chat --height 50%)', which puts a pipe on stdout by construction. runAgent injected os.Stdout unconditionally, and nib refuses every mode but --cli when a stream it was handed is not a terminal, so Ctrl+Space printed "Re-run with --cli to use the injected streams" and inserted nothing. Verified against a pty before and after. nib reads a nil stream as "not injected" and falls back to the process stream, which is how an embedder asks for nib's own behavior. That is what stdout needs: the interface renders on /dev/tty but writes the chosen command to stdout even when stdout is a pipe, and that write is the whole of the shell-capture idiom. Stdin is deliberately left injected. A piped or redirected stdin really is ignored by the interface, so the refusal is the honest answer there, and it is the one users meet: 'echo q | local-ai chat' still says to re-run with --cli, once, exit 1. Nilling stdin the way stdout is nilled would delete that silently. Stderr is not gated by nib at all and is unchanged. One case does change and cannot be kept: 'local-ai chat > out.txt' from a terminal no longer refuses, because it is indistinguishable from the widget. It renders on /dev/tty and writes the capture line to the file, which is what standalone nib does. The app.Options literal moves into agentOptions so the decision is reachable from a spec rather than being a detail of a function that takes the terminal. Both sides of the asymmetry are pinned: reinstating 'Stdout: opts.Out' fails "hands nib nothing for the process stdout", and nilling stdin fails "hands the process stdin over". Also rewrites the last comments describing the pre-v0.5.1 behavior. Assisted-by: Claude Code:claude-opus-5 [Bash] [Edit] [Write] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs(chat): say what the stream refusal actually keys on Two comments still called it the refusal to render the interface "into a pipe". That was true when both stdin and stdout were injected, but a pipe on stdout no longer refuses, so the wording now points at precisely the case that was un-refused to make Ctrl+Space work. Only a stdin that cannot be read triggers it, and both comments now say so and name the command a user meets it with, 'echo q | local-ai chat'. The agentOptions doc also said a "file a caller chose" stays injected and refused, which reads as though 'local-ai chat > out.txt' still refuses. It does not: a shell redirect arrives as os.Stdout and is nil-ed like the widget's pipe, because the two differ only in being a regular file rather than a FIFO and nib's gate does not look at that. What stays injected is a writer an in-process caller chose for itself. Says that now, in the doc and in the spec comment that had the same ambiguity. Comments only. No behavior change. Assisted-by: Claude Code:claude-opus-5 [Bash] [Edit] [Write] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs: local-ai chat is now the built-in terminal agent `local-ai chat` was a plain chat prompt and is now an agent that runs shell commands behind an approval gate, so the pages that described a REPL were wrong rather than merely thin. Adds a Terminal agent feature page at /features/terminal-agent covering the approval gate, piped runs and their exit codes, Ctrl+Space, model resolution, state directory, and the pass-through management commands (including the `--yes` caveat that leaves a plugin installed but disabled in a script). The three-way "looking for something else" notice becomes four-way and moves into an agentic-routing shortcode. Four hand-kept copies of the same paragraph is what produced the drift the new page would otherwise have added to; the shortcode takes `current=` so each page still marks itself, and errors the build on a name that is not one of the four. Assisted-by: Claude Code:claude-opus-5 [Bash] [Edit] [Write] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * website: the agent is in the binary, not a second install The nib section sold a separate tool you also install, with a GitHub link as the only way in, which is now the wrong order: the agent ships compiled into local-ai, and the standalone binary is the second reason to care rather than the first. Leads with `local-ai chat`, keeps nib as the SSH-anywhere story, and adds a docs CTA pointing at the new Terminal agent page. id="nib" is left alone because localai.io/#nib is linked from outside. The two credits on the demo clip named nib as the thing that drove the machine; they now credit the agent in LocalAI, which is the same agent. Assisted-by: Claude Code:claude-opus-5 [Bash] [Edit] [Write] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * website: fix the exit keys, the plugin warning, and the redirect gap Three claims on the chat-agent pages that the code does not back. try-it-out told readers to press Ctrl+D. nib has no Ctrl+D handler: the full-screen interface quits on Esc or Ctrl+C, and Ctrl+D is only an exit in --cli, where it arrives as ordinary tty EOF. That sentence had replaced the removed /exit and /quit text, so the page was left with no working way to leave a session. Document both modes, since they differ. The plugin warning said nothing tells you the install stopped short. It does: the command prints that the plugin was left disabled. What it does not do is say so in its exit code, which is 0 either way. That is the part a script cannot work around, and it is the reason to pass --yes. Overstating it in the paragraph that gives the advice only makes the advice easier to dismiss. Redirecting stdout no longer refuses; the interface goes to /dev/tty and only the yanked command reaches the file. It is what lets the Ctrl+Space widget capture a command at all, since a redirect and out=$(...) are the same thing to the stream gate. It was documented nowhere. A non-terminal stdin is still refused, and the new text says which of the two it is. Assisted-by: Claude Code:claude-opus-5 [Bash] [Edit] [Write] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(chat): make the CLI flags outrank the agent config file local-ai chat routed --endpoint, --model, --api-key, --trace-dir and --yolo through nib's app.Options.Defaults. Defaults are seeds: they sit beneath the config file, so the file silently undoes them. That made the flags accepted and inert, and not in an edge case, since EnsureStateDir writes base_url on the first run and the interactive picker writes model, so from the second run on the file carried a value for both. Observed against a live server: with base_url: http://127.0.0.1:9999/v1 in the config and --endpoint http://127.0.0.1:8080 on the command line, the probe hit 8080 and every agent turn posted to 9999. With model: gemma-4-e2b-it-qat-q4_0 in the config, --model lfm2.5-8b-a1b was ignored on the wire. nib v0.6.0 adds app.Options.Overrides, applied above the config file and above the bare environment block. Move the whole block there: all five values are decisions this invocation already made on the user's behalf, and a flag the config file can undo is not a flag. Nothing is left in Defaults, because LocalAI's one genuine seed, the initial base_url, is written into the config file by EnsureStateDir rather than handed to nib. Two limits come with the channel and are documented on agentOptions rather than worked around. An override can only raise a field, since nib cannot tell "set to the zero value" from "not set", so --yolo can turn approval off but nothing on the command line turns it back on over an approval_mode: auto in the file. And nib's own NIB_TRACE_DIR and NIB_YOLO are resolved after the config load and still outrank these, deliberately, upstream. The existing spec pinned that the right values reach app.Options, which they always did, which is exactly why it could not see nib discarding them. The new specs resolve the config the way app.Run resolves it, against a real config file that disagrees with every flag, and one asserts Defaults stays empty. docs/content/features/terminal-agent.md already documented --model as winning over the saved model; that was false before this change and is true now, so no docs edit was needed.

Dimitris Karakasilisandlocalai-org-maint-bot	c089caf320	feat(sycl): make the intel llama.cpp backend self-contained on any host (#10991) ... * feat(sycl): make the intel llama.cpp backend self-contained on any host The SYCL backend shipped an incomplete oneAPI runtime AND relied on a host-provided GPU driver, so it only ran inside the build container. On a bare host it died with "libze_loader.so.1 / libdnnl.so.3: cannot open shared object file", and even with the host's Intel driver installed it SIGSEGV'd during SYCL init when the host driver was built against a newer glibc than the backend's bundled loader (rolling-release distros). package_intel_libs now bundles the complete, coherent oneAPI runtime (the missing MKL ILP64 / sycl_blas / tbb_thread + oneDNN + the dlopen'd UR adapters, plus a sweep of the backend binaries' own direct deps) and the Intel GPU userspace driver (libze_intel_gpu + libigdrcl + IGC + gmm) with its OpenCL ICD manifest, mirroring how package_vulkan_libs bundles Mesa. run.sh points the Level Zero and OpenCL loaders at the bundled driver, and install-base-deps.sh installs it in the SYCL build image. Bundling the driver is safe across kernels because it talks to the host i915/xe via the stable DRM UAPI (unlike NVIDIA's kernel-locked userspace). Validated on Arch (glibc 2.43, i915): the backend loads and runs on an Iris Xe with no host Intel packages installed. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Dimitris Karakasilis <dimitris@karakasilis.me> * fix(sycl): install a driver that exists, and let the user choose their own The driver install added earlier in this branch asked apt for intel-level-zero-gpu, which is not a package in Ubuntu 24.04. apt fails outright on an unknown name, so neither driver was installed, nothing was there to copy, and the images carried no driver at all. It now comes from Intel's own repository, which has 25.18 for this Ubuntu release, against 23.43 from late 2023 in the Ubuntu archive. The archive driver does not know any card released since, so a machine with a recent Intel GPU would end up carrying a driver that cannot drive it. Anything that goes wrong during that install fails the build on purpose: an unreachable repository is a passing problem that a retry fixes, while quietly carrying a different driver, or none, is a difference nobody would notice until a user reports an idle GPU. run.sh used to overwrite whatever driver the user had chosen. Level Zero uses only the driver it is given, so on a machine with a card too new for the carried driver, the GPU would go unused with no way back. Both that setting and the OpenCL one are now left alone when already set, and the docs say how to point a backend at the machine's own driver. The OpenCL setting also used to be applied whenever the backend held a driver list, even when the driver it named had not been copied, which leaves OpenCL with nothing instead of falling back to the machine's own driver. It now requires the copied driver to be present, and the packaging leaves out the list entry of any driver it did not copy. The oneAPI images list a processor-only OpenCL library, which was being carried with nothing behind it. Two more corrections in the packaging. The scan for libraries a program is linked against only looked at files named llama-cpp-*, so turboquant and bonsai, which are also built for Intel GPUs, were left with the incomplete set of libraries this branch set out to fix; it now looks at every program in the directory. And a build that should carry a driver but ends up without one now says so, which is what a stale prebuilt base image looks like: such a backend still runs on a machine that has its own driver, so nothing fails and the only other symptom is a user reporting an idle GPU. Backends now also ask the driver to report how much graphics memory is free, without which llama.cpp reads zero on an integrated GPU, since such a chip shares the system memory instead of having its own. turboquant and bonsai get the same run.sh handling as llama.cpp. The driver is only carried by the builds that start through run.sh, because run.sh is what points Level Zero and OpenCL at it. The Python backends for Intel GPUs start differently and would never load it, so they keep using the machine's own driver rather than carrying several hundred megabytes they cannot use. Checked in a container on Ubuntu 24.04: the install brings driver 25.18 with the files where the packaging expects them, an unreachable repository fails the build, and the copied set resolves on its own once the machine's Intel packages are moved away.

The filter that builds the backend matrix listed it as an input of the Python images only, so changing it rebuilt no Go and no C++ backend, even though those run it from their own package.sh. A packaging fix aimed at the Intel llama.cpp backend could merge and reach no image, which is the same failure this rule was written to prevent. Assisted-by: Claude:claude-opus-5 Signed-off-by: Dimitris Karakasilis <dimitris@karakasilis.me> * fix(sycl): carry only the driver Level Zero uses, not the OpenCL one llama.cpp reaches an Intel GPU through Level Zero, which hands the driver programs that are already compiled and so needs only the back end of the graphics compiler. The OpenCL driver can be handed source code instead, so it needs the compiler's front end as well, and that arrives with its own copy of clang. Carrying it cost about 139 MB in every backend built for Intel GPUs, and took the carried set from 123 MB to 261 MB. Nothing here takes that path. No LocalAI code selects an OpenCL device, each backend image holds one backend, and the documentation never described OpenCL as a way to run models: the only mentions are a stale clblas row in the BUILD_TYPE table, for a llama.cpp backend that no longer exists and that no build matrix entry uses, and the sycl-ls troubleshooting hint. Before this branch the packaging carried the OpenCL loader and adapter but no driver, so the path could not work in a released image either. There is nobody to keep working. The driver list that OpenCL reads is no longer carried, and run.sh no longer sets OCL_ICD_VENDORS, so OpenCL inside a container keeps using whatever the image provides rather than being pointed at a directory with no driver in it. Checked in a container against the real 25.18 driver: the carried set is 123 MB with nothing unresolved, and Level Zero still reports the GPU with the machine's own Intel packages moved out of the way. Neither the Level Zero driver nor the compiler back end names the front end or clang among the libraries it opens by name, so the leaner set is complete for this path.

This adds a separate marketing site at the root and moves the documentation under /docs/. Docs: The existing site keeps its content tree and its Relearn theme, and now builds with baseURL <root>/docs/. Its _index.md, which held a hand written landing page, becomes a real documentation home. Every previously published URL keeps working. GitHub Pages has no server side rewrites, so .github/ci/gen-redirects.sh walks the built docs output and leaves a meta refresh plus a canonical link at each old root path. It covers bare .html files too, which is what keeps /gallery.html alive, and it never overwrites a path the marketing site already owns. Website: A second Hugo site under website/ with its own layouts and no external theme, so the marketing side does not have to fight Relearn's home rooted menu and asset pipeline. CI builds both and merges them into one Pages artifact. The design is derived from the project logo rather than invented: the navy of the triangle, the cyan of the llama, the purple of the speed bars. Those offset bars became the motion signature. The background renders a real depth-anything.cpp depth map as contour lines and switches to a locate-anything.cpp style detection overlay over the engines section. Also included: an /engines/ index driven entirely by data/engines.yaml, a /blog/ section with five posts written from the release notes and the engine benchmark suites, install.sh and a Kubernetes manifest since the site advertises both, and a rule in .agents/ that release preparation now includes a blog post and demo clips.

On filesystems that do not support symlinks (notably CIFS/SMB mounts, commonly used to back the /backends volume) the syscall fails with "operation not supported" and the whole install aborts, leaving an empty backend directory. The CUDA llama.cpp image trips this on the libcublas.so -> libcublas.so.12.x symlink. When archive.Apply fails with a link-unsupported error, reset the staging directory and re-extract with a pure-Go walker that still attempts real symlinks/hardlinks first and degrades to copying the link target's contents in place when the filesystem rejects them. mutate.Extract already flattened the layers, so the tar carries no whiteouts to interpret.

Mirror of the existing /v1/tokenize path, requested by @benniekiss in the issue thread for "complete API workflow" use cases that need to turn token IDs back into text without local processing. - Add Detokenize gRPC RPC with DetokenizeRequest{tokens} / DetokenizeResponse{content} messages. - Implement in the llama.cpp backend using common_token_to_piece, the same primitive TokenizeString already uses internally. - Other backends inherit the default Unimplemented from base.Base, in line with how Detect, Rerank, etc. are gated per-backend. - Wire up the Go gRPC interface, server, client, and in-process embed wrapper alongside their TokenizeString counterparts. - Add the schema types, ModelDetokenize wrapper, HTTP handler, route registration, RouteFeatureRegistry entry (gated by FeatureTokenize so no new feature flag is needed), and the discovery map entry under ai_functions. - Regenerated swagger reflects the new endpoint and types. - Update authentication.md to list /v1/detokenize alongside /v1/tokenize.

3 people	47097041ff	fix(vllm): apply Options[] engine flags before engine init (#11147) ... fix(vllm): apply Options[] engine flags before engine init (#11130) CLI-style flags in a model's `options:` array (`--quantization:gptq_marlin`, `--enable-prefix-caching`, `--kv-cache-dtype:fp8_e5m2`) were discarded: the backend only ever read `tool_parser`/`reasoning_parser` out of Options[], and did so *after* `AsyncLLMEngine.from_engine_args()`, where nothing it set could still reach the engine. Map `--` prefixed options onto the AsyncEngineArgs dataclass before the engine is constructed. Names are normalized the way vLLM's CLI spells them (`--enable-prefix-caching` -> `enable_prefix_caching`), values are coerced to the target field's type (bare flag -> True for booleans), and unknown or uncoercible flags warn and are skipped instead of failing the load, since Options[] is a bag shared with backend-level settings. Field types come from the annotation's base so `Literal["auto", "float16"]` (vLLM's dtype) is not mistaken for a float. Precedence is typed proto fields -> `options:` -> `engine_args:`. The production engine_args defaults seeded in hooks_vllm.go therefore skip any key the user already set as an option, otherwise the later engine_args pass would silently override it. Parser lookups now accept both spellings, so `--reasoning-parser:qwen3` selects LocalAI's parser as well. The helper's tests are stdlib-only and run in the lint workflow's dependency-light job via `make test-python-helpers`.

Model loading and the audio RPCs follow. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): keep the build-tree rpath at $ORIGIN Upstream sets CMAKE_BUILD_WITH_INSTALL_RPATH in its own directory scope, so CMake was appending its build-tree library dir to our target and baking an absolute build-host path into the shipped binary. Set BUILD_WITH_INSTALL_RPATH on the target so a package that forgets to bundle libggml*.so fails on the build machine too, instead of only on a user's box. Also document why EXCLUDE_FROM_ALL must stay on the add_subdirectory call, correct the claim that Ubuntu ships no gRPC CMake config, stop the pin comment from repeating the assignment token that bump_deps.sh rewrites, and make test-engine fail rather than pass when no test is registered.

Parse with strtol and reject on ERANGE, on a value above INT_MAX, and on any unconsumed trailing input. The error strings are unchanged. Name the whole entry in the unknown-key error too: an entry like ':value' has an empty key and left the user nothing to grep for in their YAML. Tests look keys up through a helper instead of map::at, so a prefix off-by-one fails one named check rather than aborting the binary and skipping the rest of the suite, and cover the overflow, negative and non-numeric paths.

Emit 'spk', keep 'spkrec' as an input-only alias, and correct the known-tasks lists. Three assertions were vacuous because their fixtures advertised a single task, so reversing a preference order or dropping the RPC name and the attempted pairs from the capability error all passed. Give them fixtures that can tell the orderings apart.

Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): harden seconds_to_samples against NaN and overflow seconds_to_samples is the one entry point fed by untrusted-shaped input: a float-seconds timestamp off the wire, or a boundary from a model that diverged. Its guard covered only the low side, so NaN and out-of-range values fell through to an undefined double-to-int64 cast and came back as INT64_MIN. A hugely negative sample index used later as an offset or a length is a wild pointer rather than merely a wrong timestamp. Reject NaN with the !(x > 0) form and saturate before the cast. Also round instead of truncating there. These functions exist to cross the float seconds boundary the VAD and diarize messages use, and truncation lost a sample about half the time on the samples-to-seconds-and-back round trip, starting at n=1. Pin the decode scale at INT16_MIN, pin nanosecond truncation on a nonzero fraction, and record why the clamp argument order in f32_to_s16le is load-bearing for NaN. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): map NaN PCM samples to silence explicitly f32_to_s16le relied on std::min argument order to keep a NaN sample away from std::lround, whose result is unspecified for NaN. That was too subtle to rest on a comment, and the comment was itself wrong: it warned against a spelling that the outer std::max already catches, while three real spellings leak, including std::clamp, which is the idiomatic C++17 way to write the same clamp and so the likeliest future edit. Divert NaN before the clamp and encode it as 0. A NaN sample rendered as a full-scale click is worse audio than a dropped one, and this unit converts audio that may have originated off the wire. Pin it with an exact-value check rather than a range check, since all three outcomes the plausible spellings produce are finite and inside full scale, plus an invalid-operation check that fails unless the NaN is diverted before any ordered comparison. That second check is what catches modernizing the clamp and dropping the guard together. Also bound the seconds round-trip comment, which claimed unconditionally what holds only below roughly 2^23 samples, and document NaN, saturation and that bound in the header. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): assemble transcripts from runtime spans The top-level transcript text is TaskResult.text_output verbatim. audio.cpp carries text nowhere else: speech_segments, speaker_turns and word_timestamps hold spans and labels only, so deriving the text from them empties the transcript for any producer that omits word timing, VibeVoice diarized ASR included. Fixtures cover every observed producer shape. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): keep a nested speaker turn's own label A segment sourced from speaker_turns re-derived its speaker by greatest overlap. A turn's overlap with its own span is the largest possible, so a turn nested inside another speaker's turn could only tie with the container, and the tie went to whichever came first. sortformer_diar binarizes each speaker independently and sorts by start sample, so the container always comes first and the interjecting speaker was silently erased from DiarizeSegment.speaker. choose_segment_spans now carries the label out with the span. Also pins the nearest-segment fallback against measuring from either endpoint or from segment position, which a trailing-only stray word could not do, and exercises the empty-word guard in join_words. Two fixtures that pin a rule but do not mirror any pinned family are relabelled defensive. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): serialize runs with a wedge-aware guard audio.cpp sessions are not reentrant and a wedged CUDA call cannot be cancelled, so a plain mutex would pile every worker thread behind a stuck GPU. Callers waiting past the configured bound, or arriving while the holder has already overrun it, fail fast instead. A caller that queues behind a healthy run deliberately does not stamp the clock: only the thread that takes the lock does. Stamping on arrival would restart the wedge clock on every request and hide a stuck run from everyone behind it, which is the pile-up this guard exists to prevent. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): serialize inference through an InferenceLane One audio.cpp model is loaded per backend process and its sessions are not reentrant, so concurrent gRPC handlers have to take turns. Serialization alone is not enough: a wedged GPU call cannot be cancelled from userspace, so an unbounded queue behind one stuck run would swallow every gRPC worker thread until the process is useless. InferenceLane gives handlers a lane with room for one runner. LaneEntry occupies it for a scope and gives it back on every exit, including an exception, and is the only way to take the lane at all: occupy/vacate are private with LaneEntry as the sole friend, so a caller cannot acquire without holding something that releases. LaneEntry is immovable on purpose, because a moved-from entry would have to stop releasing while the lane still recorded it as occupied. A caller either waits indefinitely or brings a millisecond budget. A bounded caller that cannot get in fails instead of waiting on, and a bounded caller whose budget is already shorter than the age of the run in the lane fails immediately, which is what stops a queue forming behind a wedged run. The two failures carry different text: one names the wait it exhausted, the other states the measured age of the run without claiming to know why it is long, since a short budget meeting a legitimately long run lands there too. The run's age is stamped only after acquisition. A waiter that published itself as holder would restart the measurement and hide a genuinely stuck holder from every caller behind it. Budget negotiation and the overrun decision are pure functions taking their inputs explicitly, so both are covered without threads or sleeping. The per-model ceiling arrives as an int of milliseconds; a request may tighten it and may never loosen it. Replaces the previous run_guard unit, which was a derivative of an Apache-2.0 file upstream and could not stay in an MIT tree. Written from a behaviour contract with no reference to the removed code. Tests: 65 checks, standard library only, single translation unit, clean under -Wall -Wextra. Mutation tested at 23/23 killed; two of those mutants exposed missing coverage and the tests were extended until they died. ThreadSanitizer clean. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): make the B10 test able to fail, and document LaneEntry Review of the previous commit found the B10 test could not fail for the reason it was named. It aged the in-flight run to about 120 ms and then tried two budgets, 30 ms and 60 ms, both under that age, so both callers took the fail-fast path. "The two failure modes do not share one message" was comparing two fail-fast messages that differ only in the budget they print, and the timeout path was never reached. The second budget is now 400 ms, well over the run's age, so that caller queues and times out, and a new check asserts which path each caller took instead of inferring it from inequality. A mutant that makes the fail-fast path emit the timeout message previously died only on B4 and B8 checks; it now also dies on B10. Comment-only changes elsewhere. LaneEntry now says it is not reentrant and does not detect reentrancy: a second entry on a thread that already holds the lane surfaces as LaneUnavailable with a positive budget, but parks silently in unbounded mode, which matters because a handler may hold one across a whole stream. The immovability note now names the shapes that work, an optional emplaced in place or a unique_ptr, rather than saying to hold the entry indirectly without saying how; all three documented forms were compiled before being written down, which is how the note came to say that an optional of an immovable type cannot itself be returned. The header's explanation of why fail-fast exists is reworded. Two clauses traced back to a specification written after reading the Apache-2.0 upstream header, and while that was judged de minimis, this unit was rewritten precisely to carry no upstream expression at all. The margin table in the report was also wrong about which wall-clock margins are load-sensitive: there are four, not one, and the tightest is the B3 arrival check, which is now flagged at the call site. No margin value changed and none moved across 65 runs.

Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): load models and cache sessions per task Loads one ILoadedVoiceModel and creates an IVoiceTaskSession lazily per (task, mode), so the same model serves both the unary and streaming RPCs. LoadModel derives the family from GGUF metadata or an explicit option and fails with INVALID_ARGUMENT otherwise, so a failed load is a gRPC error the backend probe can see. audiocpp_backend::Task mirrors engine::runtime::VoiceTaskKind positionally, and drift there is silent: every unit still compiles and every test still passes while the backend runs a different task. Two mechanisms pin it. The static_asserts in loaded_model.cpp catch an insertion or a reorder, and -Werror=switch on that one file turns an appended upstream enumerator into a build failure rather than a warning in a 600 file log. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): stop aborting the process on SIGTERM The signal handler called grpc::Server::Shutdown directly. Shutdown takes an absl::Mutex, which is not async-signal-safe: the handler can interrupt a thread already holding that mutex, and abseil's deadlock detector responds by aborting. Every SIGTERM therefore ended in exit 134 and a 'dying due to potential deadlock' stack rather than a drained shutdown. The handler now sets a lock-free atomic and returns. Server::Wait moves to a helper thread so the main thread can poll that flag and call Shutdown itself, outside any signal context. A condition variable would not have helped, because notifying one from a handler is not async-signal-safe either. SIGTERM and SIGINT both exit 0 with no stack trace, where both previously exited 134. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): correct the status, lifetime and state contracts of LoadedModel An environment fault during session creation was reported as UNIMPLEMENTED. A missing libggml-cpu-*.so surfaced to the client as 'family silero_vad advertises vad/offline but refused to create the session: Failed to initialize CPU backend', which tells LocalAI the model cannot do this and must never be retried, and sends an operator hunting a capability bug instead of a packaging one. A throw from create_task_session is now a plain runtime_error, so it maps to INTERNAL. Only a null return, where the family genuinely declined, stays a CapabilityError. The model.'s task: option was parsed and then dropped: it lived in a local that died at the end of LoadModel and had no route to RequestShape::pinned_task. LoadedModel now keeps it and exposes pinned_task(). The global model becomes a shared_ptr reached through snapshot(). An audio RPC runs for seconds and cannot hold g_model_mu for its duration, so under a unique_ptr a Free arriving mid-request would destroy the model underneath it. Handlers now take a counted reference and whichever finishes last does the teardown, outside the lock. session_for documents the streaming state contract rather than resetting the session itself. Resetting on a cache hit was tried first and is not possible: silero_vad throws 'session prepare() must be called before Silero VAD reset()', so it would turn an ordinary second fetch into a hard error. start_stream's base implementation is already a reset, so a caller that runs prepare then start_stream per stream gets a clean session; a probe against the bundled silero_vad confirms an identical replay when it does and a carried-over stream when it does not. Also: an unknown backend: name is rejected before the model loads rather than after; MainGPU is parsed instead of passed through std::atoi, which turned 'gpu1' into device 0 silently; and device carries a device_set flag, because 0 is both the default and a real device index, so MainGPU was overriding an explicit device:0 that the neighbouring threads: handling promises will win. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): serve the VAD and Diarize RPCs Both emit float seconds, converted from the runtime's sample-index spans, and both take a counted reference to the loaded model through snapshot() and hold it for the whole call: a Free arriving mid-request drops only the global's reference, so whichever request finishes last destroys the model instead of one of them running on freed weights. An AddressSanitizer build reproduces exactly that heap-use-after-free inside ggml_vec_dot_f32 when the handler keeps a raw pointer instead, which is why the shape is what it is. The inference lane is taken before session_for, not after. session_for reads and writes an unsynchronised session cache and the offline run calls prepare(), which mutates the session, so both belong inside the lane. Diarize routes before it reads the input file, so a family that cannot diarize at all says so rather than complaining about the audio first. Its per-segment text stays empty because audio.cpp's SpeakerTurn carries a span and a speaker label only, and nested or overlapping turns are passed through untouched: a sortformer turn inside another speaker's turn is correct output for overlapped speech, and LocalAI is overlap-tolerant downstream. Duration counts frames rather than floats, so a stereo input does not report twice its length. Verified end to end against upstream's bundled silero_vad, which needs no download, using the bundled 16 kHz speech asset: a synthetic tone returns nothing, correctly, because silero detects speech and a sine is not speech. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): enforce ModelIdentity on VAD and Diarize audio-cpp was the only C++ backend without the model-identity guard, and no later task in the plan added it. pkg/grpc/server.go enforces checkModelIdentity on exactly these two RPCs, for the reason #10952 records: in distributed mode a worker can recycle a stopped backend's gRPC port for another model's backend, and the controller's liveness-only probe cannot tell a stale cached route from a live one. Without this guard a stale route gets a different model's VAD or diarization answer back with a 200. The loaded identity lives on LoadedModel rather than in a separate global, which is where this differs from llama-cpp. A handler holding the model through snapshot() then necessarily judges against the identity that model was loaded with, and a concurrent reload cannot swap one without the other. The refusal is NOT_FOUND carrying the verbatim grpcerrors.ModelMismatchSentinel substring. session_for and run_offline now take a const LaneEntry & proof-of-holding parameter. The rule that both must run under the inference lane was prose, which is exactly how the plan came to specify the inverted order; it is now a compile error. Restoring the inverted order fails to build rather than racing on an unsynchronised session map with a mutating prepare(). Diarize's speaker-hint comment claimed the dropped hints were "not a silent failure". From the caller's side that is what they are, and backend.proto documents num_speakers as forcing, so the comment now says plainly that the forwarding is dead for sortformer and that the family which lands must either honour num_speakers or refuse it. read_audio_file inspects the error_code from exists(), so an unsearchable parent directory no longer reports as a missing file. The VAD handler records the stimulus that actually works, since silero correctly ignores synthetic tones and the next task would otherwise rediscover that. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): make the lane and identity guards structural Two hardenings ahead of the eleven handlers still to be written, both of which get harder to retrofit later. The lane proof-of-holding parameter was a const reference, which binds to a temporary, so session_for(rpc, shape, model->acquire(0)) compiled. Each such temporary dies at the end of its own full-expression, releasing the lane between two calls that must share one: precisely the split the parameter exists to prevent, and the form a future author is most likely to reach for because it reads as tidy. A non-const reference requires an lvalue, so the temporary form now fails to compile while the named-local handlers build unchanged. The header comment no longer implies the check is total either: it proves a lane was taken, not that it is this model's lane. The identity check was two lines each handler had to remember, with nothing failing if a new one forgot them and no C++ equivalent of model_identity_modalities_test.go to notice. snapshot() becomes snapshot_unchecked(), whose only legitimate caller is Status, since HealthMessage carries no ModelIdentity. Handlers go through snapshot_for(), which takes the counted reference, refuses when nothing is loaded, and runs the identity check before anything can route. Every handler already has to call something to obtain the model, so the guarded call is now the shortest path and skipping it means deliberately typing snapshot_unchecked. A convention that has to be remembered can rot; this cannot. Verified: the temporary-argument and inverted-order forms each fail to compile with the expected diagnostic, the real handlers build, and bypassing the guard in Diarize alone turns the identity test red on that RPC while VAD stays green.

The handler branches on the ROUTED task: for Asr the request's prompt is whisper-style decoding context and becomes a request option, for Alignment the same field IS the transcript to align and becomes the text input. Routing has already decided which. The result text is TaskResult.text_output verbatim and is never derived from the segments. audio.cpp carries transcript text in text_output and nowhere else, so deriving it returns an empty transcript for every producer that reports segments without word timing. transcript_assembly already enforces that; this commit's job is not to undo it at the proto boundary, and result_map_ctest pins it there. read_audio_file now takes the sample rate the caller needs. Both file-fed speech handlers ask for 16 kHz mono, for two reasons: silero_vad and sortformer_diar refuse anything else outright, which turned an ordinary 44.1 kHz upload into INTERNAL, and nemotron_asr emits word timestamps in its own 16 kHz feature domain whatever the input was, so only a 16 kHz buffer makes the emitted nanoseconds right. Zero keeps the file's native rate and channels, which is what source separation will need. LoadedModel::check_can_serve answers a capability refusal before the lane is taken and before the input file is read. Routing is a pure read of the immutable capabilities, so a model that cannot serve an RPC no longer waits out somebody else's run to say so. VAD and Diarize use it too.

The generated backend.pb.cc is built against the toolchain's protobuf 3.21.12. Both ended up in the binary: 476 google::protobuf:: symbols came from the archive, 278 of them also defined by libprotobuf.so, and the archive won, because once ld pulls a member in for sentencepiece's own code every reference binds to the definitions that member carries. The visible symptom is one function. ParseContext::ParseMessage(MessageLite*, const char*) is what a generated _InternalParse calls for a submessage field and for nothing else, so flat messages parsed and nested ones did not: a TranscriptResult carrying segments serialized to correct bytes that the same process could not read back, and TranscriptLiveRequest, a oneof of submessages, could not have been parsed at all. Underneath that, 3.21 generated code was running 3.14 arena, ArenaStringPtr and ExtensionSet code. -Wl,--exclude-libs does not fix it. It makes those symbols LOCAL in .dynsym and the parse still fails, because the binding was decided at static link time and no visibility flag revisits it. Setting SPM_PROTOBUF_PROVIDER to "package" before add_subdirectory points sentencepiece at the protobuf the generated code was already built against. Zero google::protobuf:: definitions remain in the executable afterwards, every nested message round trips, and citrinet_asr, which parses a SentencePiece ModelProto at load time and would break first if this were wrong, still tokenizes and transcribes correctly. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): fix the segment text a transcription response is built from Segment text is not decoration. core/http/endpoints/openai/transcription.go routes response_format text, srt, vtt and lrc through schema.TranscriptionResponse, which builds the entire body out of Segments[].Text and never reads the top-level text. So for those four formats the segment text IS the response. nemotron_asr emits one word_timestamp per SentencePiece token, and the word boundary is carried as a LEADING SPACE on the piece ("So", "me", " call"). join_words inserted a space unconditionally, so response_format=text returned "So me call me na ture ," while the correct sentence sat unread in the top-level field. The separator is now chosen from the words themselves: whole words are space-joined, subword pieces are concatenated, and one leading space anywhere selects the latter. Concatenating the real nemotron pieces reproduces text_output exactly, verified end to end. This does not touch the top-level text, which is still text_output verbatim. The rule that forbids deriving the transcript from the segments is about the direction segments -> text; segment text has no source other than its words. Two smaller corrections in the same area: timestamp_granularities ["word"] set only "word_timestamps", a key no family in the pinned upstream reads. It now sets "return_timestamps", which qwen3_asr does read and which both runs its forced aligner and shortens its chunk window, so asking for word granularity no longer silently returns nothing. The request-option comment claimed more than it delivered. prompt, translate and temperature are read by no ASR family, and are forwarded only so a family adopting them works unchanged; the comment now says so per key, and gives TranscriptRequest.diarize the same explicit treatment threads already had. Also: the shipping target now carries -Wall -Wextra -Wpedantic, which it never did, so "the build is clean" starts meaning something; and fill_transcript_result no longer swallows a null response pointer, since answering OK with an empty transcript is the one failure mode this unit exists to prevent.

AudioTransformResult carries one dst while htdemucs and mel_band_roformer produce several named stems from a single run, so inference runs ONCE, every stem is written as a sibling file <dst-stem>.<name>.<ext>, and params[stem] selects which one dst receives, defaulting to vocals and falling back to the first output. An unknown stem name is INVALID_ARGUMENT listing the real stem names rather than a silent substitution, and the selection happens before the first write so a refused request leaves no files behind. params[stem] is consumed here and is not forwarded into the engine's request options. The stem decision lives in stem_selection, which is stdlib only and therefore tested by backend/cpp/run-unit-tests.sh. It also validates the names, because they come from the model (htdemucs reads them from the GGUF's config.sources) and each becomes a component of a path this backend writes: a name carrying a path separator would escape the caller's output directory, and two stems sharing a name would silently overwrite one another. Both files are read at their native rate and channel count. Separation forces it, since demucs and roformer refuse any rate but 44.1 kHz and lose the stereo image that separates a centred vocal from a wide mix. The conversion families all resample internally (seed_vc, vevo2, miocodec, chatterbox were each checked), so passing the file through unchanged is also strictly better than band limiting it to 16 kHz first. Verified end to end against htdemucs f16 on a 44.1 kHz stereo mix: four stems plus dst, dst byte identical to the selected stem, params[stem] selecting a different one, an unknown stem refused with no files written, and mono input preserved as mono output. Also against miocodec for the single output path, where params[stem] is refused rather than ignored.

The post-run refusal stays as the backstop for a separation-routed family that returns no stems anyway. The typo'd-stem-name case still needs the run, since no framework header publishes the stem names before one. Stem names carrying control bytes are refused. GGUF strings are length prefixed and demucs reads its sources from JSON, so an embedded NUL survives to here: two names differing only after the NUL are distinct std::strings, so the duplicate check passes them, and then path::c_str() truncates both and they open the same file. That is exactly the silent overwrite the duplicate check exists to prevent, with the .wav lost as well. A failed write is now INTERNAL rather than INVALID_ARGUMENT. The destination is LocalAI's own generated-content directory, not anything the caller named, so a full disk or a permission fault there is a server fault and is worth retrying, which is the opposite of what INVALID_ARGUMENT tells a client. An empty output path stays INVALID_ARGUMENT. Two comment corrections and one clarification: the separators' required rate is their checkpoint's declared samplerate rather than a hardcoded 44100, seed_vc resamples with soxr and falls back to sinc-hann, and the "no files left behind" guarantee covers a refused request, not a write that fails partway through the loop. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(audio-transform): stop folding every upload to 16 kHz mono, and name the separation stems Two defects that made source separation unusable through LocalAI's own API, even though the backend served it correctly over gRPC. /audio/transform normalized every upload to 16 kHz mono s16 through utils.AudioToWav, with no way past it. htdemucs and mel_band_roformer refuse any rate but their checkpoint's own and separate a centred vocal from a wide mix using the stereo image, so every separation request through the HTTP API died with "HTDemucs prepare() sample rate mismatch: expected 44100, got 16000" while the same call over gRPC worked. The fold is not wrong, it is backend-specific: LocalVQE's echo cancellation genuinely wants 16 kHz mono and needs the reference in the same shape. So it becomes a declaration, BackendCapability.AudioTransformInputMono16k, set for localvqe and for nothing else. A backend that declares nothing gets its upload unchanged, which means no backend has to opt in to work. utils.AudioToWavPreservingShape is the non-folding conversion: a 16-bit PCM WAV passes through byte for byte at any rate and channel count, anything else is transcoded to WAV with its rate and channel layout kept. The other defect is that the run-once stem design bought nothing. A separation backend writes every stem beside dst from one inference, but AudioTransformResult carried only dst, so the other three were files no caller could find and a caller wanting all four had to run four separations. AudioTransformResult grows a repeated AudioTransformStem, the backend fills it, core/backend validates that each path really is inside the generated-content directory it handed over, and the endpoint publishes them as an X-Audio-Stems JSON header beside the existing X-Audio-Input-Url. JSON because a stem name is the model's own string and could contain any separator a hand-rolled format would use. Verified end to end through the HTTP endpoint with htdemucs f16 on a 44.1 kHz stereo file: 200 with a 44.1 kHz stereo body, all four stems named and fetchable through /generated-audio/, body byte identical to the selected stem, and params[stem]=drums returning a different one. The same upload sent to a model whose backend is localvqe still reaches the backend as 16 kHz mono, confirmed both by the engine's own rate refusal and by the persisted input file. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(audio-transform): reject extensible WAV from the passthrough, escape stem URLs, convert stems with dst Four fixes from the second review, plus one bug they made visible. isPCM16Wav tested only the bit depth, and go-audio's IsValidFile never looks at the format tag, so a 16-bit WAVE_FORMAT_EXTENSIBLE (0xFFFE) upload was passed through untouched where the old fold would have transcoded it. audio.cpp's WAV reader accepts 16-bit only when the tag is 1, so such a file died with "unsupported WAV encoding". Extensible is what many DAWs and Windows tools write and music files are this endpoint's new headline input, so it is a first-contact failure rather than a corner. The check now requires tag 1, with a spec that fails against the old implementation. Stem URLs are percent-escaped. A stem name is the model's own string and legally contains a space, a '#', a '?' or a '%'; an unescaped '#' truncates the URL before the request is even sent. The name field keeps the raw name. sample_rate and response_format are applied to the stems as well as to dst. Applying beat documenting: dst IS one of those stems, so leaving them alone broke the "dst duplicates the selected stem" invariant the whole design rests on, and both conversions are no-ops when unset. A stem whose conversion fails is dropped from the header rather than advertised in the wrong shape. Verifying that turned up why it had never been noticed: the two fields were never bound at all. The request arrives as multipart/form-data and echo's binder falls back to the FIELD NAME without a form tag, matching only case-insensitively, so "SampleRate" never matched "sample_rate" and "Format" never matched "response_format". Both were documented in the endpoint table and silently ignored. Two form tags fix it, and with them the conversion is observable end to end. Docs: audio-transform.md now documents what LocalAI does to an upload before the backend sees it, which backend gets the 16 kHz mono fold and why, params[stem], and the X-Audio-Stems header with a worked example. Also records the known limitation that the fold lookup is on the bare backend name, so pinned variants (vulkan-localvqe) do not match, and points at IsLlamaCppBackend as the suffix-tolerant precedent. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): serve the TTS and SoundGeneration RPCs TTSRequest.voice is treated as a speaker reference clip when it names an existing regular file, which makes routing prefer VoiceCloning, and as a named preset otherwise, in which case it travels as VoiceReference::cached_voice_id. Both the clip and SoundGenerationRequest.src are read at the file's own rate and channel count: upstream's own CLI and server do exactly that, every consuming family resamples internally and mostly with a better resampler than ours, and ace_step and stable_audio resample their input per channel, so a downmix here would delete the stereo image they are built to consume. The request builders live in their own unit rather than in grpc-server.cpp's anonymous namespace so they can be tested; grpc-server.cpp has a main() and cannot be linked into a test binary. The option keys are the whole point of these functions, so each one was grepped against the pinned upstream and the accounting is written down beside it. instructions maps to "instruct", which is what upstream's own server maps the OpenAI field to and what qwen3_tts and omnivoice read, and to "caption" for irodori_tts; the style tag is spelled "instruct" too, because "instructions" is looked up nowhere. duration maps to "duration_seconds", read by all three generation families, with the proto's own name kept only as a forward-tolerant alias. Keys that no family reads say so. Both handlers answer a capability refusal before taking the lane and before any file read, so a model that cannot synthesise does not queue behind somebody else's run to be told no. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): stop emitting an empty style language, and name the missing clip StyleCondition::language was set whenever has_language() was true, with no !empty() guard, while the language option twelve lines below had one. core/backend/tts.go sets Language unconditionally, so has_language() is true on every request LocalAI sends and carries "" when the caller named none. An engaged-but-empty style language is worse than an absent one: supertonic reads text_input->language behind its own !empty() guard and then overrides it from style->language with no guard at all, so "" replaced its "en" default and its tokenizer threw "invalid Supertonic language: ". Every /v1/audio/speech request that set instructions and no language would have been an INTERNAL against a supertonic model. A plain request never saw it, because the style condition only exists when instructions are non-empty, which is why the chatterbox end to end run did not catch it. TTS also stops discarding the Route that check_can_serve already returns. A family routed to voice cloning without a reference clip used to be refused from inside its own prepare(), which meant an INTERNAL naming neither the RPC nor the field to set; chatterbox advertises clon and no tts, so that was every preset-only request to it. It is now an INVALID_ARGUMENT naming TTSRequest.voice, answered in about 4 ms, and it cannot misfire because has_voice_reference is what selected cloning in the first place. Reading CapabilitySet::supports_speaker_reference to generalise this stays a follow-up. The src read carries a written caveat rather than a family blocklist, because ace_step's editing routes legitimately need src: setting src on a stable_audio model corrupts the heap and aborts the process in the pinned upstream, and the only thing keeping that off the network is that schema.ElevenLabsSoundGenerationRequest has no field for it. Nobody reading that Go schema would know why, so the reason is recorded where the field is read. build_tts_shape is extracted so TTSStream cannot describe the same request differently, and it arrived untested: two mutations of it survived until a test_tts_shape case was added. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): serve the TTSStream and AudioTranscriptionStream RPCs TTSStream leads with a streaming WAV header carrying 0xFFFFFFFF sizes, matching the convention backend/go/vibevoice-cpp established, so an HTTP client can start playback before the full PCM exists. Its chunks are read from StreamEvent::named_audio_outputs and not audio_output: supertonic, omnivoice and voxcpm2 all put their streamed audio there and leave audio_output empty until the very end, so reading the obvious field yields a stream with no audio in it. The finish_stream result is the family's own merged whole rather than a tail, so it is emitted only when nothing was streamed. Streaming transcription sends incremental deltas and degrades to a single delta plus the final result on families that offer no streaming ASR, which is the same message sequence with fewer deltas. The four streaming ASR families disagree on what partial_text means: nemotron_asr, vibevoice_asr and higgs_audio_stt report incremental fragments while voxtral_realtime reports the whole hypothesis and reports it twice, so the reconciliation lives in one tested unit rather than in the handler. nemotron_asr reports only through the stream event sink, and only from inside finalize, so the audio driver installs one and clears it again before returning: the session is cached and a sink left holding the caller's frame is a use after free waiting for the next stream. begin_stream is now the only implementation of the streaming state obligation, prepare then start_stream. Streaming sessions are cached, and what clears the previous stream is start_stream's reset; a family override that dropped it would break every call site with no compile error, so there is one call site. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): keep streaming deltas on UTF-8 boundaries, refuse dtypes that abort TranscriptStreamResponse.delta is a proto3 string, whose wire format requires valid UTF-8. voxtral_realtime reports its hypothesis as a concatenation of raw token BYTES (tokenizer_text.cpp:171-183), so the cumulative difference between two consecutive reports is eventually a lone continuation byte, and the C++ runtime serializes that with only a logged warning while the Go runtime refuses to unmarshal it: the client loses the remaining deltas AND the final_result. Measured on a trace of a non-ASCII sentence, 11 of 31 messages failed to unmarshal and every accented character was lost. TranscriptDeltaTracker now holds back an incomplete trailing sequence and merges it into the next fragment; reconcile flushes it, which it always can because the final text is complete. The same trace now unmarshals in full with zero failures. A streaming buffer whose float count is not a whole number of frames is refused rather than truncated. The integer division dropped the tail floats from the fed audio and therefore from the transcript, with no diagnostic; vibevoice_asr refuses the same thing from the other side of the call. A supertonic GGUF whose weights are not f32 is refused at load. It reaches ggml_concat with mismatched operand types and ggml_abort takes the whole backend process down on the first request, so nothing downstream can report it: the model loads, then every request kills the process. Attributed rather than assumed, the unary TTS path aborts identically, and upstream records that package as untested. The refusal names the orig package and says what to run before deleting the guard. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): stop a repeated lead byte from orphaning the next delta The first UTF-8 fix closed the cumulative half only. Rule 2 discards a fragment the known text already starts with, and when that fragment is the LEAD BYTE of a new character it looks exactly like a repeat of an older character beginning with the same byte. It was discarded rather than held, its continuation bytes then arrived alone and began the next delta, and utf8_complete_prefix_length only ever inspected the trailing sequence, so a delta invalid at the FRONT went out whole. Through a real Go proto.Unmarshal the review's four-character repro gave 3 deltas, 2 unmarshal failures and a lost transcript. Reachable from the incremental families, not only from voxtral: nemotron_asr's decoder cuts at a byte offset and vibevoice_asr's common_prefix_size compares bytes, so both split characters. Measured over 30,000 randomized incremental traces, 53.28% of Japanese traces and 9.52% of French ones carried at least one delta the Go runtime refuses. Two changes. Rule 2 no longer judges a fragment that ends mid-character, so the lead byte is held instead of swallowed and the character survives intact; the cost is a few duplicated bytes in a shrinking cumulative report, which no pinned family produces. release() additionally drops leading orphan continuation bytes, so no delta can begin mid-character whatever the rules above it decide. Losing a byte keeps the stream alive; emitting one ends the RPC and takes the final_result with it. Post-fix all 60,000 traces produce zero unmarshal failures, and the cumulative streams plus both pure-ASCII incremental streams are byte-identical to the previous commit, so nothing changed for the families already working. The weight-dtype allow list moves to family_gate, where it is stdlib-only and pinned by a test rather than only by a comment. Two comment citations corrected. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): read only an exact repeat as a repeat, not any prefix Rule 2 discarded any partial the known text merely started with. For a cumulative family that is a duplicate; for an incremental family it is an ordinary short fragment that happens to coincide with the start of the transcript, and it was dropped, silently corrupting the text. Pure ASCII, no multi-byte character anywhere: the fragments "pure ", "ascii ", "trans", "c", "ri", "p", "t" left the client holding "pure ascii transcrit". Over 5,000 randomized traces per transcript, 9.50% of pure-ASCII and 29.12% of French traces ended with the client holding something other than final_result.text, with a 200 and no diagnostic. Both incremental families emit fragments that small routinely, since nemotron_asr cuts at a byte offset and vibevoice_asr at a common prefix. Narrowing rule 2 to an exact repeat drives that to zero on all six transcripts and changes no cumulative stream at all: 30,000 randomized cumulative traces are byte-identical to the previous commit. What rule 2 guarded was established from upstream rather than from its own comment. The only duplicate any pinned family produces is voxtral_realtime's, where process_available_stream_chunks feeds each event to the sink from inside its loop and returns the last of the batch, so that event arrives twice with byte-equal text. A duplicate is an exact repeat, so equality still covers it. The case given up is a cumulative report that SHRINKS, which no pinned family can produce: voxtral decodes a token vector that is only push_back'ed and cleared by reset(), so within a stream it can only grow. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): serve the AudioTranscriptionLive RPC The one bidirectional stream this backend serves. The client sends a TranscriptLiveConfig, then TranscriptLiveAudio frames; the server acknowledges with ready, emits deltas as the audio arrives, and sends final_result once the read side closes. There is no offline fallback: live transcription has to consume audio incrementally, so a family with no streaming ASR is refused rather than served a batch run, which is what this RPC's Streaming-only mode_candidates list already says. The driver is a new sibling of run_streaming_audio, run_streaming_live, because the audio does not exist yet: instead of slicing a buffer it pulls frames from the caller until the read side closes. It installs the same ScopedStreamSink in the same order, which is not optional, since nemotron_asr returns a bare event from process_audio_chunk and reports every partial through the sink from inside finalize(). It buffers the wire's frames up to the family's own preferred window rather than feeding whatever size the client's audio callback produced, and it does not call finish_stream at all when no audio arrived, because nemotron_asr throws "finalize requires streamed audio" and an empty transcript is the truthful answer to transcribing nothing. Three things the handler had to get right and one it cannot: - The audio contract. A live request carries no samples, but nemotron_asr's streaming prepare() throws without an audio contract, and build_preparation_request derives it from TaskRequest::audio_input, so that field is an EMPTY buffer holding only the rate and the channel count. - 16 kHz or a refusal. The families express their spans in their own 16 kHz feature domain whatever the input was, and live frames cannot be resampled on the way in the way a file can, so an 8 kHz session would return timestamps 2x off with a 200. core/backend hardcodes 16000 anyway. - A mid-stream Config is refused. backend.proto calls it a decoder reset, but deltas already on the wire cannot be retracted, so a reset would leave the final text contradicting the transcript the client assembled. Ignoring the message would hand a client that believes it reset the decoder a transcript that silently continues the audio it thought it discarded. - The stale-route identity check cannot run here: TranscriptLiveRequest carries no ModelIdentity in either arm of its oneof, so snapshot_for does not instantiate for it. snapshot_unchecked's comment now names that as a second legitimate class of caller and says the fix is a proto change. eou and eob stay false. They exist for cache-aware models that emit end-of-utterance and end-of-backchannel tokens; audio.cpp's StreamEvent has no equivalent signal, and a client uses eou to decide the speaker yielded the turn, so a guess inferred from silence cuts people off mid-sentence. The lane is held for the whole stream, which is as long as the user keeps talking: the streaming session is stateful and cached, so a concurrent run would interleave two callers' audio and corrupt both transcripts. Verified against nemotron_asr over a real connection with a 14 s WAV in 512-sample frames: ready first, 59 incremental deltas with no repeated prefix, concat(deltas) equal to final_result.text, word timestamps in nanoseconds, eou and eob false. citrinet_asr answers UNIMPLEMENTED naming the family and listing asr/offline. A config followed by a close returns an empty final_result rather than hanging, and a first message that is not a config is INVALID_ARGUMENT. Two concurrent streams both return the complete transcript. Two cleanups on lines Task 12 touched, folded in. The DtypeAllowList terminator is now asserted at compile time: the reported out-of-bounds read did not exist, the single entry does terminate, but the loops have no other bound and any edit that widened an entry would walk off the end. And the dtype guard now short-circuits on "is there a table entry" through a new predicate rather than on the emptiness of the description string, which would have skipped the check on an entry with an empty allow list, i.e. on precisely the entry that refuses every dtype. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): bound the lane a live stream can hold AudioTranscriptionLive holds the model's inference lane for the whole stream, which is correct (the streaming session is stateful and a concurrent run would interleave two callers' audio) and newly dangerous. Every other RPC holds the lane across compute, or across a write to a slow reader, and both of those terminate on their own. A live stream instead blocks in a client-driven read, and a peer that goes silent WITHOUT closing the stream never terminates anything: the lane stays taken and every other request against that model queues behind a client that stopped speaking. live_watchdog is a one-shot idle timer that ends the stream when no frame has arrived inside a window. It is standard library only, so it is unit tested without an engine. gRPC's synchronous Read has no timeout and cannot be given one, so the only way to unblock it is ServerContext::TryCancel, which decides the wire status itself: the client sees CANCELLED rather than the DEADLINE_EXCEEDED the handler returns, the reason is logged, and the lane coming back is the point. When it fires the read loop throws rather than reporting end-of-input, so the driver does not go on to finalize a decode nobody is waiting for. It is armed only after the lane is taken and disarmed as soon as the read side closes, and both ends matter. Arming earlier would cover acquire(), which legitimately blocks while another live stream runs, so a queued caller would be cancelled for waiting its turn. Disarming later would cover our own decode, where a window overrun is not a peer going quiet and cancelling would throw away the transcript the client is waiting for. The window is the new live_idle_timeout_ms option, 30 s by default, 0 meaning no limit. core/http/endpoints/openai/realtime.go drives a 300 ms ticker and feeds every tick that produced new audio while a turn is open, so 30 s of silence is a hundred ticks that delivered nothing. It is also longer than any pause a speaker takes mid-utterance, which is the case that must never be cut off, and backend.proto lets one stream span many utterances, so a client that pauses longer between them raises the option rather than discovering it. Two smaller corrections in the same handler: - check_can_serve now runs BEFORE the sample rate check. pkg/grpc/grpcerrors/errors.go degrades to the file path on UNIMPLEMENTED and on nothing else, so a live-incapable model asked at a wrong rate was answering INVALID_ARGUMENT and costing the caller its fallback. - a negative sample rate is refused instead of silently becoming 16000. Zero still means 16000, which is what the proto documents; -1 is malformed rather than absent and gets the same refusal every other bad rate gets. And one thing recorded rather than changed, at the handler: "live" here means incremental INPUT, not low latency, and with the pinned families it does not yet mean incremental OUTPUT either. nemotron_asr's process_audio_chunk only appends to its buffer, so its whole decode and every delta happen inside finalize(), after the client closes its send side. The policy-window buffering is inert for that family and matters only for vibevoice_asr and higgs_audio_stt. Verified on the wire with live_idle_timeout_ms:3000. A silent client acked at 371 ms and was cancelled at 3.371 s; a second live stream opened one second later received its ack 2.37 s in, i.e. at the instant the first was cancelled, and then transcribed successfully on the same cached session. Without the watchdog it would still be waiting. Re-ran the live transcription (ready first, 59 incremental deltas, concat equal to the final text, word timestamps in nanoseconds, eou and eob false), the citrinet refusal at both a right and a wrong rate (UNIMPLEMENTED either way now), and Task 12's AudioTranscriptionStream on nemotron_asr, which is unchanged. Mutation testing the watchdog found a weakness in its own test: the destructor test slept past the window inside the watched scope, so a destructor that DETACHED the thread instead of joining it passed unnoticed. The test now uses a window longer than the scope, which kills that mutant, and says why.

Each now returns UNIMPLEMENTED naming the loaded family, what that family does support, and the upstream limitation, instead of the generated base class's bare status. The reasons live in a table in capability_routing.cpp so they are data rather than literals copied into five handlers, and so a test can assert every one of them. The five claims this was planned against were re-read at the pinned upstream e800d435d130dc776baf6f3e6129bb62b1495c89, and one did not hold. "audio.cpp streams tts and asr only" is false: silero_vad advertises vad with RunMode::Streaming. The refusal stands on the narrower claim that survives, that no family advertises streaming for any task AudioTransform routes to, and a test asserts the refuted wording does not come back. VoiceEmbed is the one refusal whose request carries a ModelIdentity, so it runs the #10952 check before answering: a stale route must get NOT_FOUND and the router's sentinel, not "audio.cpp cannot embed speakers" about a model that is not loaded here. It cannot use snapshot_for, whose no-model branch would tell the caller to load a model when no model can help, so it takes the reference through snapshot_unchecked and checks identity itself. That function's comment now names three classes of caller instead of two. The two bidirectional surfaces refuse without reading their stream, verified with a client that writes a config and eight frames first and gets the status rather than hanging.

It said s2s is "offline voice conversion ... which converts one clip into another speaker's voice", which is true of miocodec and false of vevo2: vevo2's s2s route is `editing` and only `editing` (default_route_for_task and route_matches_task in src/models/vevo2/session.cpp), documented as "Edit source speech into new target text while using the target voice" and requiring --target-text, so it rewrites what was said. vevo2's voice conversion is its separate vc task. It now reads "offline clip-to-clip processing against a target voice, declared only by miocodec (voice conversion) and vevo2 (speech editing)", and a test asserts the miscast cannot come back. The conclusion is unchanged: neither family converses. That defect was undetectable on the wire, since vevo2 does not load here, which is the argument for upstream_absence_ctest.cpp. It links engine_runtime purely to interrogate make_default_registry() and asserts the five premises the refusal reasons rest on: no codec task kind, no family advertising spk, no streaming for sep/vc/svc/s2s, miocodec advertising exactly vc and s2s, and s2s advertised by exactly miocodec and vevo2. The last two are exact sets, so an addition fails here rather than leaving a message stale. A positive control proves the registry is populated and the query works before any absence is believed, and every assertion has a reproduced negative control. This turns an AUDIO_CPP_VERSION bump from "remember to re-read five prose paragraphs" into a test failure. unsupported_surface now switches over UnsupportedRpc with no default label, so -Wswitch reports a sixth enumerator added without a row at build time; the runtime bounds guard it replaces is deleted. The AudioTransformStream reason had a true premise and an overreaching conclusion: an offline sep family could be buffered into a stream, as other LocalAI backends do. It now says this backend declines to offer a buffered offline call in disguise, rather than implying impossibility.

As a warning that is not enough: adding a sixth enumerator and building the shipping target gives exit 0, a binary and one warning, and the trailing `return surfaces[0];` then answers the new RPC with AudioEncode's codec reason. That is a confident, specific and false statement about audio.cpp on the wire, on the one code path whose entire job is to be truthful about what this backend cannot do, and it is worse than the runtime fallback it replaced, which at least named itself as a bug in this file. capability_routing.cpp therefore joins loaded_model.cpp on the existing -Werror=switch pin, whose comment already made this argument for the engine enum. The comment now covers both files. The pin stays per-file rather than project-wide because upstream's own ace_step/vae_decoder.cpp has unhandled -Wswitch cases of its own. Verified: a sixth enumerator now fails `make grpc-server` with exit 2 and no binary; appending a 14th VoiceTaskKind upstream still fails loaded_model.cpp, so the two pins fire independently; both reverted clean. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): package the backend image Bundles the dependency closure for the from-scratch image, the dlopened ggml CPU-variant shared objects that ldd cannot see, and upstream's bundled silero_vad and marblenet_vad assets so VAD works with no download. The bundled loader sits in the package ROOT rather than at lib/ld.so. run.sh execs it, which makes /proc/self/exe name the loader, and this backend has two consumers of that path: ggml discovers the libggml-cpu-*.so by listing dirname(/proc/self/exe), and resolve_model_path expands bundled:<name> under the same directory. Rooting the loader makes the binary, the ggml objects and assets/ share the one directory all three resolution mechanisms agree on. llama-cpp's lib/ld.so layout would need assets/ moved into lib/ as well. The image builds against apt gRPC and protobuf, like Dockerfile.ds4 and unlike Dockerfile.privacy-filter. The from-source gRPC that install-base-deps.sh and the base-grpc-* images supply vendors protobuf 26, which pulls abseil into message_lite.h; with SPM_PROTOBUF_PROVIDER=package that collides with sentencepiece's vendored mini-abseil and every absl::internal reference becomes ambiguous. Noble's protobuf 3.21.12 predates the abseil dependency and is the pair every earlier verification of this backend ran against.

With BUILD_TYPE=cublas ggml is static and links CUDA::cuda_driver, so grpc-server carries DT_NEEDED libcuda.so.1 and the gate would have rejected the very absence the copy loop created, failing every cublas build in CI. One regex now feeds both. Building a control for that found a second defect: ld.so --list refuses to trace an object with an unresolvable dependency at all, exiting 127 without emitting a per-library line, so the "=> not found" rule was dead code and no exemption could have applied to it. The gate now traces with LD_TRACE_LOADED_OBJECTS and LD_LIBRARY_PATH, which reports the missing name and exits 0, and which is also what run.sh does at run time. Adds a layout assertion so a future move of the loader into lib/ fails the build instead of shipping a package that resolves bundled: models into lib/assets and finds no ggml CPU backend, and records for Task 16 that the Darwin script must not be a straight copy of privacy-filter-darwin.sh, which never calls package.sh and would silently drop assets/. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): register the backend with CI and the gallery Adds the five Linux matrix entries (cpu amd64/arm64 sharing a tag-suffix so the manifest merge fires, cuda 12, cuda 13, vulkan), the path-filter case that keeps later PRs touching backend/cpp/audio-cpp/ from getting zero CI jobs, the bump-bot entry pointing at the AUDIO_CPP_VERSION pin in the backend Makefile, the gallery meta plus its -development variant and the image entries for every variant, and the Makefile docker-build wiring. The matrix entries carry base-image only, with no builder-base-image, unlike the llama-cpp and privacy-filter blocks they sit next to. The prebuilt quay.io/go-skynet/ci-cache:base-grpc-* images ship a from-source gRPC whose protobuf v26 depends on abseil, and this backend's sentencepiece is built with SPM_PROTOBUF_PROVIDER=package, so it sees real abseil's absl::lts_20240116:: internal alongside its own vendored plain absl::internal and every absl::internal:: reference becomes ambiguous. Building against base-grpc-amd64 fails at sentencepiece-static.dir/error.cc.o with "reference to 'internal' is ambiguous". Dockerfile.audio-cpp installs apt's gRPC/protobuf 3.21.12 itself, which is also the pair every unit and end-to-end run of this backend has been verified against, and the CUDA toolkit therefore has to come from base-image. No Darwin matrix entry and no metal gallery entries: the Metal build needs scripts/build/audio-cpp-darwin.sh, a backends/audio-cpp-darwin make target and a routing step in backend_build_darwin.yml, none of which exist yet, so an entry added now would be routed to build-darwin-go-backend and look for backend/go/audio-cpp/. The inferBackendPathDarwin case and the DARWIN_BESPOKE_BUILDERS membership are in place, inert, so that adding the entry later is a one-line change that cannot be claimed by the generic Go path. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): pin the CUDA architectures, drop the vulkan variant Upstream sets CUDA_ARCHITECTURES to `native` on the engine_runtime target whenever CMAKE_CUDA_ARCHITECTURES is unset at root scope, and docs/build/ linux.md says so outright. ggml's own default does not rescue it: it list(APPEND)s in the ggml subdirectory scope, which never reaches the root scope where the engine_runtime property is decided. No CI runner has a GPU for `native` to enumerate, so both cublas entries would have gone red on the very commit that first turns a CUDA build on. Pin the list in backend/cpp/audio-cpp/Makefile, selected by CUDA_MAJOR_VERSION, which Dockerfile.audio-cpp now forwards from the CI build-arg it was previously discarding. The values are copied from ggml's own version guards rather than invented, so engine_runtime and ggml compile for the same set: CUDA 12 keeps the Maxwell/Pascal/Volta virtual archs and stops at 120a-real, CUDA 13 drops them and adds 121a-real. The `a` suffix is used rather than `f` because the latter needs CMake 3.31.8 and Ubuntu Noble ships 3.28.3. Verified by driving CMake 3.28.3's own CUDA architecture validator over both lists, with 120f-virtual as the rejected control. Drop the vulkan matrix entry, its two gallery entries, the vulkan capability key on both metas and the Vulkan tag. Every other vulkan backend gets its Mesa ICD drivers from .docker/install-base-deps.sh, which package-gpu-libs.sh then bundles; Dockerfile.audio-cpp calls neither and installs only libvulkan-dev and glslc, so the image would ship a Vulkan loader that finds no GPU. No CI job runs a vulkan image against real hardware, so that would have passed green and failed in users' hands. BUILD_TYPE=vulkan stays supported for local builds. Also note on the cublas entries that cuda-major-version now selects the architecture list and that cuda-minor-version and the base-image tag encode the same toolkit, and correct the stale entry counts on matrixEntryKey. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): build for Darwin Metal Bespoke C++ Darwin path like ds4 and privacy-filter: an includeDarwin matrix entry, a backends/audio-cpp-darwin make target, a gated workflow step, and the metal image entries plus metal/metal-darwin-arm64 capability keys in the backend gallery. The build script deliberately does NOT reassemble the package the way privacy-filter-darwin.sh does. It runs the backend's own `make package` and copies the result, so the Darwin package keeps the root-level layout the Linux one has: grpc-server, run.sh, the ggml objects and assets/ in one directory, with lib/ for the dylib closure. Hand-assembling would drop assets/, and assets/ is what makes the bundled: model paths resolve with nothing downloaded. The dylib walk is a full transitive closure rather than the single level ds4 and llama-cpp do, because Homebrew's grpc++ pulls libgrpc, abseil, upb, cares and OpenSSL that grpc-server does not link itself, and a level-1 walk ships a package that only works on a machine that already has Homebrew grpc. Two fixes folded in, both in the backend Makefile: - an EMPTY CUDA_MAJOR_VERSION fell through to the CUDA 12 architecture list, which contains 120a-real and so needs nvcc >= 12.8. A local BUILD_TYPE=cublas build on a 12.0-12.7 host failed to compile where upstream's documented default (native) worked. EMPTY now maps to native, 12 and 13 keep their lists, and any other non-empty value is an error on cublas builds. CI always passes a major, so CI is unaffected. - the Darwin branch now points CMake at Homebrew's keg-only libomp. AppleClang ships no OpenMP runtime and nothing is symlinked into /opt/homebrew, so FindOpenMP finds neither the library nor the header, and audio.cpp calls find_package(OpenMP REQUIRED) whenever ENGINE_ENABLE_OPENMP is on. Without the hint the macOS build would have died at configure time. If the keg is absent the build disables OpenMP instead of failing. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): make the Darwin fallbacks loud and the rpath walk complete Review follow-up on the Darwin Metal build. The OpenMP fallback was silent. If brew --prefix libomp ever comes back empty, CI produced a green Metal package with 108 #pragma omp directives across ~30 files compiled out, and clang says nothing about an ignored omp pragma without -Wsource-uses-openmp, so the only trace was one absent flag inside a set -x cmake line. That regression would have been blamed on Metal. It now warns. The @rpath arm of the dylib walk had no live candidate when it was written, on the reasoning that a Metal build links ggml statically. The OpenMP fix in the same commit made libomp.dylib one, and whether Homebrew records it as an absolute opt path or as @rpath/libomp.dylib is not observable from Linux. The walk now expands @rpath, @loader_path and @executable_path against the object's own LC_RPATH entries, and only fails when nothing on disk answers, printing the rpath list with the error so a failure on a machine nobody can attach to explains itself. Also: ADDITIONAL_LIBS now go through the closure rather than a bare cp, so they are deduplicated and their own dependencies bundled; build/darwin/lib is created explicitly instead of relying on package.sh pre-creating it; the libomp probe uses nested ifneq rather than $(and ...), which needs GNU make 3.81 and would otherwise expand empty and take the OFF branch on an older make; and -DOpenMP_ROOT is quoted like its CUDA sibling. Verified with a Linux harness that runs the script verbatim against a stubbed otool: a level-2 transitive dep, an @rpath dep reachable only through LC_RPATH, and an ADDITIONAL_LIBS dep are all bundled, a dependency cycle terminates, system libraries are skipped, the packaged tree has assets/ at the root beside grpc-server with the dylibs in lib/, and both failure paths exit non-zero.

LocalAI fills ModelFile by joining ModelPath onto the configured model string (pkg/model/loader.go, LoadModelWithFile), and only sets it from a managed artifact otherwise, so a model YAML saying `model: bundled:silero_vad` arrives as ModelFile "/models/bundled:silero_vad" and Model "bundled:silero_vad". The prefix therefore never matched through the normal load path: it matched only for a hand-written LoadModel call that left ModelFile empty, which is exactly how task 15 verified it, and every model YAML using the form failed with "model path does not exist: /models/bundled:silero_vad". Both fields are now checked, Model first, so the zero-download VAD path the package ships assets for is reachable the way it is documented. A caller that puts the form in ModelFile still works, so task 15's verification stands. Compiled clean; the runtime check could not run on this host, whose system libprotobuf/libre2 have gone missing (the pre-existing grpc-server binary no longer resolves its libraries either), so it wants a container run.

Modality is a single string and the import form chips on a fixed key set, so it registers as tts with the other modalities named in the description rather than under an invented key the UI would bucket as "other". Adds a features page covering the option namespacing, the routing table per endpoint, the RPCs this backend declines and why, the bundled VAD path, the separation stem behaviour, and the family gotchas (supertonic needs the orig package; chatterbox advertises cloning and no plain tts; nemotron_asr defers its whole decode to finalize so live transcription emits nothing until the client half-closes, unlike higgs_audio_stt and voxtral_realtime). Every option name and family capability in it was read off the pinned upstream checkout. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): test resolve_model_path, and correct the family names The bundled: fix in 842443cd7 shipped without a test, which is how the bug got there: task 15 verified the form with a hand-written LoadModel that left ModelFile empty, and that is the one shape the server never produces. Four cases in streaming_driver_ctest, which already links loaded_model.cpp, pin the PRODUCTION shapes instead. The first fails against the pre-fix source (returns the joined /models/bundled:silero_vad); the other three are the branches the bundled: lookup now runs in front of and must fall through for. Three family names in the docs were the source directory rather than the registered family, on pages whose whole argument is that these names cannot be guessed: demucs is htdemucs (demucs/loader.cpp:22), roformer is mel_band_roformer (roformer/assets.h:15), and moss is TWO families, moss_tts_local and moss_tts_nano. The hyphenated ASR names are underscored to match, here and in the compatibility table. The supertonic dtype note claimed more than the evidence carries. The f16 abort is a local observation, identical through TTS and TTSStream; upstream's docs/gguf.md leaves the 16-bit column untested and records q8_0 as "No (unsupported weight dtype)", which says unusable rather than fatal. Both are still refused, because the allow list is what the family can run. Corrected in family_gate.h, family_gate.cpp and the docs together, since the docs inherited the wording from the code. The importers tripwire says in the file that it is a tripwire: it exercises no audio-cpp behaviour, and the registration assertion lives in backend_test.go. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * gallery: add audio.cpp models covering every served RPC One representative model per RPC group of the audio-cpp backend, plus the two bundled VAD models, which need no download at all because the assets ship inside the backend package. Every hash was computed with sha256sum on the downloaded file. Quantizations come from upstream's tested-status table in docs/gguf.md rather than a default of q8_0: supertonic ships the orig package (its q8_0 is recorded as an unsupported weight dtype and its f16 aborts in ggml_concat), and nemotron_asr and htdemucs ship f16 because their q8_0 builds are recorded with drift while 16-bit is a clean pass. Diarization and separation use the diarization and audio_transform usecases, not transcript: /v1/audio/diarization and /audio/transform filter the default model on FLAG_DIARIZATION and FLAG_AUDIO_TRANSFORM respectively, so a transcript flag would have hidden both models from their own endpoints. The forced aligner sets parameters.language, which the transcription endpoint uses as the fallback when no language form field is sent, because the family requires both a transcript and a language. All ten entries were run twice: once against the raw gRPC server, and once installed with local-ai models install and called through the HTTP endpoint. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * gallery: correct the audio.cpp entries' licenses Swept all ten entries against the real upstream named in audio.cpp's tools/model_manager.py rather than against the audio.cpp repo's own license. Three were wrong: supertonic apache-2.0 -> openrail weights come from mlx-community/supertonic-3-mlx, and both it and Supertone/supertonic are openrail citrinet apache-2.0 -> other pulled from NGC nvidia/nemo/stt_en_citrinet_256, governed by the NGC Terms of Use sortformer other -> cc-by-nc-4.0 nvidia/diar_sortformer_4spk-v1 is CC BY-NC 4.0, and the gallery already uses that exact string, so there is no reason to obscure a non-commercial bar The license field is one word, so citrinet and sortformer also gained a sentence saying why they are restricted. The other seven were confirmed correct against their sources. Also drops an unverified claim from the nemotron description. It said the model drives the realtime transcription session; that endpoint actually calls TranscribeStream, and the live RPC reaches LocalAI only through realtime_semantic_vad.go. Neither path was exercised here, so the description now states only the two calls that were. MarbleNet gains the NeMo upstream under urls: for parity with silero. No sha256, quantization, usecase or model choice changed. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(audio-transform): bound sample_rate, keep same-named uploads apart Four defects the whole-branch review found on the Go side, plus two comment corrections. sample_rate is a disk-exhaustion hazard. The branch added the `form:` tag that makes the field bind for the first time, so the resample path went from dead to live, and utils.AudioResample interpolates the int straight into ffmpeg's -ar with no bound. Measured with ffmpeg 7: -ar 999999999 on a 0.01 s clip writes 20 MB and exits 0, which scales linearly to the reported 3.9 GB for one second, into a GeneratedContentDir nothing sweeps, and convertStems repeats it once per separation stem. Clamped to 8000..192000 in the handler, before the temp dir and before the model is touched, and rejected with a 400 outside it. The low end was reported as "a 0-byte file". It is not: -ar 1 writes a 78-byte header with no audio behind it, whose declared data size still claims 70 bytes, so go-audio parses it as a 35 SECOND file and a size check does not see it. The guard therefore compares the declared data chunk against the bytes actually on disk, and AudioResample now fails rather than returning a WAV carrying nothing. Both parts of a transform request land in one temp dir, and the raw copy was named only after the client's basename, so `-F audio=@mic/clip.wav -F reference=@loopback/clip.wav` wrote "raw-clip.wav" twice. Since AudioToWavPreservingShape hardlinks an already-PCM16 WAV rather than copying it, the reference part's os.Create truncated the inode audio.wav pointed at: mic and reference came out identical, which makes an echo canceller null everything and return near-silence with a 200. The raw copy now carries the form field name. audio-cpp had no BackendCapabilities entry, so VoiceCloningForModel returned nil before it ever consulted the model's tts.voice_cloning override and every `voice: "profile:<id>"` request was refused with a 400, on a backend that ships audio-cpp-chatterbox whose family serves cloning and not plain TTS. Registered with its RPCs, usecases and the reference-audio contract, and deliberately without the 16 kHz mono fold, which its separation families cannot survive. GetBackendCapability was exact-match only, so every pinned gallery variant read as an unknown backend: vulkan-localvqe lost the 16 kHz mono fold that used to be unconditional and started failing inside LocalVQE, and the usecase gate does not stand in for it because BuildFilteredFirstAvailableDefaultModel returns early once the client names a model. Lookup now falls back to the meta name by stripping the gallery's hardware prefix and release-channel suffix, exact match first so nothing can be shadowed. Same class as #10945. Also corrected: the AudioTransformRequest comment claimed echo's binder falls back to the field name, which it does not in either direction (bindData binds ONLY tagged fields and `continue`s otherwise; `model` arrives from setModelNameFromRequest's c.FormValue). And the stable_audio `src` heap corruption caveat now lives on ElevenLabsSoundGenerationRequest, where the Go developer who would add the field can see it, instead of only in C++. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(audio-cpp): refuse a task pin the RPC cannot serve, and stop empty frames holding the lane The model's `task:` option is copied into the request shape by all nine handlers, which is correct, but resolve_route then replaced the RPC's candidate list with the pin WHOLESALE and never asked whether the pin was something that RPC routes to. One pin therefore bled across all nine surfaces, and because the family still supported the pinned task the result was a wrong 200 rather than an error. Reproduced live: nemotron with task:asr made Vad return 200 with zero segments after a full ASR decode, so 14 seconds of speech was reported as silence, and Diarize did the same; silero_vad with task:vad made AudioTranscription return 200 with empty text and four segments whose spans were VAD segments, which combined with response_format in {text,srt,vtt,lrc} building the body solely from Segments[].Text yields a well formed SRT of four timed EMPTY cues. It also contradicted the documented contract, that a family which cannot serve a request is refused rather than rerouted. A pin is now checked against the RPC's admissible task set before it is adopted, and the refusal names both the pin and the RPC. The set is derived from task_candidates with every shape flag set rather than restated, so a task added to an RPC's candidates cannot become inadmissible by omission. Every legitimate pin survives, and the test asserts all fifteen of them alongside the eight crossings that must not. The live watchdog was defeated by empty frames. idle.touch() ran on ANY message, before the has_audio and pcm.empty() filters, so a peer writing unset-oneof or zero-length frames faster than the window held the lane indefinitely while feeding the decoder nothing. There is one lane per model and one model per process, so that is a single client denying the whole backend, which is what the watchdog exists to prevent, and the thrown text already said "no audio frame arrived". The touch moved below the filters, which are now a named predicate so the distinction is testable rather than a call order nobody can see. Three comments corrected against measurement rather than reasoning: - CMakeLists claimed zero google::protobuf:: definitions remain in the executable. nm -C --defined-only reports 2515, and that is expected: they are generated code, sentencepiece::ModelProto's own _InternalParse among them. The claim that holds, and the one the ABI fix is actually about, is that no vendored protobuf RUNTIME is linked and ParseContext::ParseMessage is UNDEFINED in the executable, resolving to libprotobuf.so. - refuse_cloning_without_a_clip's "cannot misfire" paragraph had its reasoning backwards. Routing picks VoiceCloning as the FALLBACK when there is no clip, which is the case being caught; chatterbox, which ships in the gallery, advertises clon and no tts at all, so every voice-less request lands there. - audio_units read "2.1 min at 96 kHz" for index 11289602, which is 1.96 min. 2.1 min is 96 kHz's OWN first failure at 12288002. Both were remeasured and the note is now a per-rate table.

It is safe today only by luck: upstream's 44 tests all put "test" at the FRONT of the filename (17 test-*.cpp, 27 test_*.cpp, zero *_test.cpp), so the glob misses every one of them, and nothing enforces that. This gate runs on every PR for every backend and compiles each match as a standalone translation unit with nothing but nlohmann/json on the include path, so the day upstream adds or renames one test the gate goes red repo-wide on an Apache-2.0 file nobody here wrote. audio-cpp-darwin.sh now logs the raw otool -L output and the parsed LC_RPATH list unconditionally, before the walk. Both awk filters in that script assume a column layout nobody working on this can observe, since it runs only on the CI Mac, and a green first Darwin run proves nothing about the assumption: an awk that silently matched nothing yields an empty dependency list, which reads exactly like "no non-system dependencies" and packages happily. Both filters otherwise feed process substitutions, so their input never reached the log. It also lists every symlink in the package and fails on one that cannot resolve inside the image. A dangling link does not fail anything else here, because every assertion tests with -e, which follows links; it fails at dlopen on a user's Mac. Links are NOT banned outright, which the review suggested but which would break the libggml.dylib -> libggml.0.dylib chain the `cp -a` above exists to preserve. What is banned is a link that resolves on the build host and will not resolve in the image: a broken one, or an absolute one pointing outside the package.

A pinned name therefore resolved the capability by stripping and then missed every case in the switch, falling through to the permissive default: cuda12-vibevoice-cpp advertised voice cloning for the realtime 0.5B model, metal-coqui for tacotron2, cuda12-crispasr for a pure ASR model, cpu-qwen3-tts-cpp for CustomVoice. Each of those is a model that cannot clone, so /v1/audio/speech accepted a profile: voice it had to fail on inside the backend rather than rejecting it with a 400, and the UI advertised the capability too. resolveBackendCapability now returns the key the entry was found under, and callers that branch on backend identity use that key instead of the name they were handed. The exact-match-first order is unchanged, so a backend genuinely registered under a variant-looking name still keys on its own name.

It is the one audio.cpp task with a shipped gallery model and no way to find it. Verified against the real model rather than inferred from the capability list: AudioTransform with chatterbox-q8_0, speech as audio_path and a speaker clip as reference_path, returns a 5.08 s 24 kHz mono WAV at -25.5 dB mean and zero stems, which is the single-output shape voice conversion should have. The description now says which endpoint reaches that half and warns that installing this next to a source-separation model gives /audio/transform two candidates, so the model should be named rather than defaulted.

Both were driven end to end against the real weights through the backend before being written, not inferred from the capability tables. audio-cpp-irodori-voicedesign covers vdes. TTS carrying `instructions` routes to the vdes task, so the voice is described in words rather than supplied as a clip. Verified: "a calm elderly woman speaking slowly with a warm, gentle tone" over an 8.76 s 48 kHz mono render at -16.8 dB mean, and a closed-loop citrinet pass recovers the sentence with the accent drift expected from a Japanese-first model read by an English recogniser. audio-cpp-seedvc-singing covers svc, and pins task:svc because nothing else can reach it. seed_vc advertises svc and ordinary voice conversion, no request signal means "this input is singing", and auto-routing resolves the tie to voice conversion every time. Verified with the pin: 5.04 s 44.1 kHz output whose closed-loop citrinet transcription is exact. s2s deliberately has no entry, and the reason is not effort. miocodec is the only upstream family whose speech-to-speech route needs no text, and it returned audio with correct duration and level but no recoverable speech in four independent attempts: the stale build, v2 q8_0, v2 orig (the variant upstream records as a clean Pass), both tasks, and matched 44.1 kHz inputs on both sides. vevo2's route refuses with "Vevo2 text/prosody route requires text_input or target_text", and session.cpp:897 fills target_text only from request.text_input, which AudioTransform has no field to carry. The same vevo2 weights convert voice correctly through the default route with an exact ASR round trip, so the model and the plumbing are both healthy; it is the s2s route specifically that this RPC cannot express.

The params map is the only channel this RPC has that reaches the engine, so the text travels through it and apply_transform_text_input unpacks it after the params have been copied into task.options. Before this, s2s was not awkward to reach through /audio/transform, it was unreachable, and it was the last audio.cpp task kind with a real model and no way to get to it. target_text is canonical and text is its alias, the order vevo2's own option table declares them in, so a request setting both gets the canonical one rather than whichever the map happened to store first. An empty value falls through to the next candidate instead of ending the search. language rides along only when a text was found: on its own it conditions nothing, and manufacturing a text_input for it would route a plain separation request carrying a language hint through the text path. The keys are left in task.options rather than erased, because vevo2's loader advertises target_text as a request option and a family reading it there keeps working. Nine tests, all confirmed failing on behaviour against a stub that returned false before the implementation was written. Verified end to end afterwards: vevo2-q8_0 with task:s2s and params[text] returns a 5.12 s 24 kHz output whose closed-loop citrinet transcription is exact, and htdemucs separation with no text param still returns its four stems, with and without params[stem]. audio-cpp-vevo2-speech-to-speech ships that route. Every audio.cpp task kind with a loadable family now has a gallery entry; spk remains the only gap and has no family upstream at all.

Both are the kind of thing a user only discovers from a refusal or, worse, from output that looks right and is not.

Annotated in the repo's existing style rather than restructured, with the reason spelled out, because a bare suppression is worth nothing to the next reader.

Every entry in the table has to compile even though a host only ever dlopens the one its own CPU supports, so a single unbuildable variant fails the whole image. gcc-14 accepts it, which is exactly the fix llama-cpp already carries in .docker/llama-cpp-compile.sh; this is the same problem reached by a different Dockerfile. Applied to every arm64 BUILD_TYPE rather than to the CPU one alone, and that differs from llama-cpp on purpose. llama-cpp needs it only for its pure-CPU image because its GPU builds run llama-cpp-fallback, which builds no variant table. This backend's Makefile turns ENGINE_ENABLE_CPU_ALL_VARIANTS on for every non-Darwin build, GPU included, so an arm64 GPU image would hit the identical error. The matrix has no arm64 GPU entry today, which is precisely why gating on an empty BUILD_TYPE would leave the trap armed for whoever adds the first one.

Dimitris Karakasilis	c6c347ce13	feat(stablediffusion-ggml): make VAE tiling configurable (#11216) ... GenerateImage hardcoded TilingParamsSetEnabled(vaep, false), so tiled VAE decoding was unreachable from a model config even though all four upstream setters were already bound in main.go. Sampling runs in latent space, but the final VAE decode expands to full resolution and needs one large compute buffer. At 1024x1024 that buffer exceeds 8GB, which fails on two kinds of device: cards without the VRAM for a full-frame decode, and drivers that cap a single allocation regardless of how much memory is free. Mesa RADV reports a 4GiB maxMemoryAllocationSize, so a Radeon 8060S with 74GiB of device-local heap still cannot serve that decode: [INFO ] sampling completed, taking 251.82s [INFO ] decoding 1 latents ggml_vulkan: Requested buffer size exceeds device buffer size limit: ErrorOutOfDeviceMemory [ERROR] vae: failed to allocate the compute buffer [ERROR] decode_first_stage failed for latent 1 Every sampling step completes and then the run is discarded at the last stage, so the whole generation is wasted. Add three options, parsed in Load and applied per generation: vae_tiling:true enable tiled decoding (bare flag also works) vae_tile_size:512 tile size, or 512x384 for a rectangle vae_tile_overlap:0.25 overlap between tiles Tiling stays off unless requested, so existing models are unaffected. Tile size and overlap only reach the library when the operator set them, which keeps upstream's defaults rather than pushing a zero, and an unparseable value is treated as absent for the same reason. Truthy spellings match what load_model already accepts for its own bool options, and the bare-flag form matches diffusion_model, so no new convention is introduced.

That field is the only thing tying a terminal event back to the response.create that asked for it. Our own doc comment on ResponseCreateEvent says so — "the metadata field is a good way to disambiguate multiple simultaneous Responses" — and it is what makes an out-of-band response (conversation: "none") usable at all: a client running one alongside the spoken conversation has no way to tell its own answer from the conversation's, so it waits for a reply it already received and gave away. Found from the client side: a headless text turn injected into a live session was answered correctly in about a second, and the caller still blocked until its own two-minute timeout because it could not recognise the answer. Carry the map on liveResponse so all three terminals (in_progress, cancelled, completed) report it, and leave it omitted when response.create sent none.

localai-org-maint-botandDaria Korenieva	9bfd71387b	feat(stores): add Valkey Search vector store backend (#11196) ... * feat: add Valkey Search vector store backend Add a new built-in Go gRPC store backend 'valkey-store' that implements the four Stores RPCs (Set/Get/Delete/Find) against the Valkey Search module (FT.*) using the pure-Go github.com/valkey-io/valkey-go client. It is selected via the existing per-request 'backend' field on /stores, so there is no proto or HTTP API change, and it mirrors the in-memory local-store while adding persistence across restarts and opt-in HNSW. Each vector is a Valkey HASH keyed by hex(little-endian float32); the index is created lazily on first Set (FLAT+COSINE by default), cosine similarity is derived as 1-distance, and namespaces get a collision-resistant token. Includes unit tests (valkey-go mock) and env-gated integration tests against valkey/valkey-bundle, plus build/matrix/gallery wiring and docs. Assisted-by: Kiro:claude-opus-4.8 golangci-lint Signed-off-by: Daria Korenieva <daric2612@gmail.com> * Address review feedback: recover persisted index dimension, harden Find - Load now recovers the persisted vector DIM from FT.INFO (not just index existence), so a post-restart Set/Find validates against the real DIM instead of silently re-learning a wrong one and dropping mismatched vectors from the index. This also restores Find's dimension check after a restart. - StoresFind treats a dropped/missing index as an empty store (empty result, no error) and clears the stale indexCreated flag, matching local-store's empty-store behaviour. - StoresSet reuses checkDims for its per-key length check so the four RPCs share one dimension-guard implementation. - Add unit tests for FT.INFO dimension recovery, loadIndexState, and the dropped-index Find path.

This removes every env access from the backend and routes config through the model-config seam every other backend uses. - config.go: loadConfig(opts *pb.ModelOptions) now parses the model config `options:` list (key:value strings, split on the first ':') instead of os.Getenv. Option keys mirror the old VALKEY_* names without the prefix (addr, index_algo, distance_metric, ...). Defaults, fail-fast validation and the mandatory client name are unchanged. - store.go: Load threads opts into loadConfig; TLS comments/errors renamed off the VALKEY_* names. - core/backend/stores.go: StoreBackend and NewVectorStore take a *config.ModelConfigLoader, resolve the per-store ModelConfig by store name, and pass its Options (and Backend when unset) to the backend via WithLoadGRPCLoadModelOpts. No config -> default backend + built-in defaults, preserving the zero-config experience. - Endpoints/routes/application: thread the config loader to StoreBackend. - Unit + integration tests: configure via options; the integration test passes addr through the model-config path (VALKEY_ADDR is now only the test harness locating the server). - docs + .env: document the model-config options, drop the env var table.

Weight-free unit tests cover resolution/validation/param mapping — CI never downloads the multi-GB GGUF set or runs inference. - CPU SIMD variants build into per-variant directories (the shared libggml sonames collide across variants, unlike sd-ggml's flat renamed-.so scheme); run.sh picks one via /proc/cpuinfo. - CI wiring: backend-matrix entries (cpu, cuda12/13, vulkan amd64+arm64, l4t, l4t-cuda13, darwin metal), index.yaml meta + latest/master image entries, bump_deps tracking of the pbr-textures branch, changed-backends.js mapping, top-level Makefile targets. - Importer: auto-detects trellis GGUF repos/URIs (registered before llama-cpp so the .gguf match isn't stolen) and expands any trellis URI to the full 10-file component set spanning the three LocalAI-io HF repos. - Gallery: trellis2-4b (full PBR + 1024 cascade) and trellis2-4b-geometry (512 untextured) with verified sha256s.

Parsing happens before any GL so stats and errors render without WebGL2. - use3DHistory stores past generations (params, input thumbnail, and the GLB blob itself) in IndexedDB with keep-newest-20 eviction — GLBs are multi-MB binaries localStorage can't hold — and the page offers a download button for the active GLB. - Wiring: CAP_3D capability constant (FLAG_3D — the exact string /api/models/capabilities serves), threeDApi, router entries, Studio tab, vite dev proxy, en locale keys. - e2e: render-smoke entry plus a focused spec that feeds a real one-triangle vertex-PBR GLB through the parser/viewer and exercises IndexedDB persistence, selection, deletion, and API errors.

Richard Palethorpe	49ef40a187	feat(classifier/VAD): support voice control on low power devices (#10804) ... * feat(llama-cpp): route Score through the slot loop Score previously bypassed the slot loop with a direct llama_decode: a conflict guard aborted the whole process if scoring raced generation, the config validator had to reject score alongside chat/completion/embeddings, and every candidate re-decoded the full shared prompt. Add SERVER_TASK_TYPE_SCORE to the (patched) upstream server so score tasks are scheduled like any other slot work: generation and scoring serialize naturally, the shared prompt is decoded once per call, and the slot's prompt cache carries the conversation prefix across calls. Context checkpoints at the score boundary and at the cache-divergence point keep SWA/hybrid/recurrent models (e.g. LFM2.5) from re-prefilling the whole prompt per candidate: warm-turn scoring on a 6-option set drops from ~8s to ~0.5s on a desktop CPU. The conflict guard and the validation split are removed; declaring score with generation usecases on one config is now supported and shares the slot cache.

Below-threshold turns take the configured fallback (none / canned reply / generate); empty transcripts and unaddressed turns (wake word not mentioned) skip scoring entirely. The scoring probe defaults to the latest user message only — small scorers echo canned replies from prior turns back as the top option otherwise. Built for hardware that can afford prompt processing but not decode: with slot-based Score the option list stays KV-cached across turns, so a turn costs roughly one forward pass over the new words. session_update_error events now carry the validation cause instead of a generic message.

Audio that keeps producing segments without a committing pause (steady noise a mic pipeline lets through, music, continuous speech) grew the buffer toward the 100MB cap with each tick rescanning all of it — O(n^2), measured at ~3.3ms of silero per buffered second: past ~90s retained, ticks run back to back and pin ~4 cores until the stream stops. Silero's recurrent state only carries a few hundred ms of context, so rescanning old audio buys nothing. Clip the slice handed to the VAD to the largest silence the commit test can need to measure (server_vad silence window or the semantic eagerness fallback) plus a warm-up margin, and rebase the returned segment times so every downstream consumer keeps whole-buffer coordinates. An open turn whose clipped window is all silence now commits (the silence outran the window) instead of being discarded as no-speech. Independently, retain at most 90s of raw buffer, rebasing the live-feed and EOU cursors on trim — this also bounds the previously unbounded VAD-error path. Turn boundaries are otherwise unchanged: no forced commits, no new coordinator states. pipeline.turn_detection.vad_window_sec can widen the scan window; values below the automatic floor are ignored. The tick body is extracted into vadTick so specs can drive turn detection synchronously (same shape as classifySoundWindow); the babble reproduction that pinned 4 cores now plateaus under 10% of one core.

Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * perf(llama-cpp): score all candidates in one batched decode One scoring call is now a single SERVER_TASK_TYPE_SCORE task: the slot decodes the shared prefix (prompt + longest common candidate token prefix) once, then forks one sequence per candidate off it (metadata-only for the unified KV cache, copy-on-write for recurrent state) and decodes every candidate's unique tail in one llama_decode. Previously each candidate was its own task that restored the boundary checkpoint and re-decoded its full tail sequentially, paying per-candidate task and decode overhead. The context reserves SERVER_SCORE_FORK_SEQS extra sequence ids (and recurrent-state cells) beyond the parallel slots via the new common_params::n_seq_score_forks. Forking requires the unified KV cache (already this backend's default) since per-sequence streams would shrink n_ctx_seq; an explicit kv_unified:false disables forking and Score calls that need it fail cleanly. Candidates beyond the fork/output budget decode in successive chunks. Wire contract and scores are unchanged: per-token logprobs are stitched from the shared region and the forked tails. Verified bitwise deterministic call-to-call and independent of candidate order (no cross-fork leakage via equal-length candidate swap); ranking matches the per-candidate implementation on the drone battery (winner softmax 0.99996 vs 0.99997), and >16-candidate chunking, prefix-of-another and empty candidates all pass. Measured on a desktop CPU: warm /api/score calls 0.52s -> 0.23s; warm realtime classifier turns 196-303ms. The 9-candidate drone turn decodes ~17 unique tail tokens in one batch instead of nine sequential ~220ms checkpoint-restore tasks. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * fix(realtime): gate scoring capacity by model usecase Reserve llama.cpp scoring slots only for models that explicitly declare the score usecase, while allowing score to coexist with chat and completion. Reject incompatible unified-KV settings and classifier activation on models without scoring capacity. Propagate application defaults when resolving realtime and preload pipeline stages so unset thread counts are resolved consistently without overriding explicit model settings. Assisted-by: Codex:gpt-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * fix(ci): honor APT mirrors in the prebuilt llama-cpp compile step The builder-prebuilt path installs gcc-14 with apt directly and ignored the APT_MIRROR/APT_PORTS_MIRROR build args the from-source path already honors, so an ubuntu mirror outage broke every arm64 backend build. Pass the args into the stage and run apt-mirror.sh (already in the build context via COPY . /LocalAI) before the apt step. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(realtime): classifier argument slots via constrained completion Hybrid classify-then-complete: a classifier option's canned tool call can declare typed argument slots (number | enum | string, with defaults and prompt hints) referenced as "{{name}}" in the arguments template. When the option wins, the slots are filled by a short grammar-constrained completion that continues the exact scoring prompt — rendered by the same cached ScoreClassifier, so the llama.cpp prompt cache is already warm — with the chosen route JSON re-opened at the first slot field. A GBNF grammar pins the field skeleton and frees only the values; temperature 0, a couple dozen tokens at most (~300ms on a desktop CPU for two slots). Slot declarations and hints ride the option descriptions in the shared system prompt, informing scoring and the fill alike at no per-turn token cost. The localai.classifier.result event carries the final arguments and a fill_latency_ms. On inference failure the slots' defaults apply; a slot without a default fails the response (or falls through with fallback.mode: generate). Slot filling requires completion alongside score in the scoring model's known_usecases. Verified end-to-end on the Pi drone demo: "fly forward three meters" in distance mode classifies forward and infers {"distance": 3, "units": "meters"} in ~310ms, and the drone flies exactly 3 units. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(realtime): splice filled slot values into classifier replies A classifier option's spoken reply can now reference its tool's argument slots ("Going forward {{distance}} {{units}}."): the values inferred by the slot-fill completion — or the recovery defaults — are spliced into the reply as plain text before it is emitted, so what the assistant says confirms what it actually inferred. Placeholders without a value stay literal, and options without slots are untouched. FillToolArguments now returns the raw slot values alongside the spliced arguments JSON to make the reply templating possible.

Assisted-by: Codex:gpt-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(realtime): prewarm the classifier scoring prompt on registration Swapping a session's classifier option list (a voice-switched command mode, for instance) made the next turns pay a full re-prefill of the new option-list prompt — measured 2.4s vs 0.3s warm on a desktop CPU, and worse: on hybrid-memory models like LFM2.5, whose state cannot be partially rewound (llama.cpp can only restore checkpoints), *every* probe change re-prefilled from scratch whenever the last checkpoint missed the probe boundary, so even same-list turns intermittently cost full prefills. Registering an option list (pipeline seed or session.update) now fires a best-effort background prewarm: two throwaway scores with distinct probes. The first prefills the new option-list prompt; the second, diverging exactly where per-turn probe text starts, plants the backend's rewind point (KV checkpoint) at the stable-prefix boundary that every real turn reuses. The prewarm hides behind the canned mode-switch reply — by the time it finishes speaking, the cache is warm. Idempotent per option set, detached from the registering request's lifetime. Measured on the drone demo (LFM2.5-1.2B, desktop CPU): first turn after a mode switch 2374ms -> 340ms; intermittent same-list full prefills (1.3-2.1s) all -> under 0.5s. For clients that swap lists frequently, options: [parallel:2] on the scoring model additionally keeps one slot per list via prefix-similarity routing (+26MB RSS, unified KV). Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * perf(llama-cpp): checkpoint scoring at the caller-declared stable prefix Hybrid-memory models (LFM2.5 shortconv, Qwen3.5 deltanet — where new small models are headed) cannot rewind their state, so any prompt-cache reuse that needs a rewind falls back to a full re-prefill. For classifier scoring that meant every probe change re-processed the whole option-list prompt: the server's checkpoints were placed reactively (at wherever the previous task happened to diverge), so a checkpoint past the next divergence was erased rather than restored — measured as intermittent 2-10s turns on prompts with a 95%+ common prefix. The classifier now computes the probe-invariant prompt prefix once (the byte-wise common prefix of two synthetic probe renders) and declares its length with every Score request; the server maps it to a token boundary and forces a KV checkpoint exactly there on each score prefill. That checkpoint sits at or before every future divergence under the same option list, so it always survives and always restores — repeat scoring costs probe+candidates regardless of how the probe changes. Also: - prewarm reruns on every option-list registration instead of memoizing per list: with boundary checkpoints a redundant rewarm costs two probe-sized decodes, while skipping one after a slot eviction (three lists sharing fewer slots evict in LRU cascades) silently moves a full re-prefill onto the user's next turn - new llama.cpp backend option rs_seq:N exposes bounded recurrent-state rollback outside speculative decoding; measured impractical for deltanet-scale states (65GB for 64 snapshots on Qwen3.5-4B) but cheap insurance for small-state models - docs: the multi-list recipe (parallel:N + sps:0.5 — the default slot similarity threshold funnels distinct lists onto one slot) Measured on the drone demo (LFM2.5-1.2B scorer, desktop CPU), steady state: every turn 285-421ms including mode switches, vs 2.4s post-switch and intermittent 1.3-2.9s re-prefills before.
