fix(gallery): use published F16 mmproj for qwythos-9b (#11792)

fix(ui): size model fit against the cluster and move node labels into the selector (#11765)
* fix(ui): move node labels into the scheduling selector field The scheduling page kept a node-label browser open above the rules whether or not anyone was writing one, while the field that actually needs labels, the rule's node selector, was two bare text inputs with no hint of what the cluster reports. The browser is gone. The selector's key input now completes against the label keys the cluster uses, and the value input offers only the values that key takes. The roster already loads for the page, so the suggestions cost no request, and a roster that fails to load costs the admin the hints and nothing else. Suggestions stay suggestions: a key no node reports yet still commits as typed, which is how an admin writes a rule before labelling the nodes for it. Assisted-by: Claude:claude-opus-5 golangci-lint eslint playwright Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed): size model fit against the cluster, not the frontend The models page asked the frontend how much memory a model may occupy. In distributed mode the frontend is usually a GPU-less pod while every model runs on a worker, so a fleet of GPU nodes was told it could only run the smallest CPU build. The variant picker's fits flag and its auto-selection came from the same place, as did the hardware recommendations. The registry now reports the largest single healthy backend node. The largest node, not the fleet total: a model loads into one node, so four 16GB workers are not a home for a 40GB model. An operator-set VRAM budget caps a node's contribution, because the scheduler refuses a load above that ceiling anyway, and a GPU node beats a CPU node holding more system RAM. GET /api/resources and GET /api/models carry this as an additional cluster object. Their aggregate and ram fields keep reporting the frontend's own hardware, which is what the resource monitor shows. Variant selection judges backends against the union of the capabilities present in the cluster, the way backend discovery already did. Every path degrades to the local host: no cluster object in single-node mode, and none when the registry cannot be read, so a hiccup narrows the answer back to single-node behaviour rather than marking the whole catalog too large. The verdicts now name the node they belong to, since a model fits somewhere or nowhere.

fix(vram): persist remote probe metadata (#11487)
* fix(vram): persist remote probe metadata The startup warmer repeated remote size and GGUF metadata probes after every restart because both caches lived only in memory. Store successful HTTP probes for 24 hours so frequent restarts reuse the prior results. Bound the cache, reject invalid records, and purge it when gallery data changes. Local model files continue to bypass persistence. Assisted-by: Codex:gpt-5 * fix(vram): check temporary file cleanup The lint gate rejects the unchecked cleanup call in the persistent cache writer. Assisted-by: Codex:gpt-5.6 [golangci-lint] * fix(vram): make persistent cache optional Remote metadata probes can transfer enough data that operators need control over disk reuse and startup warming. Gallery autoload now gates both behaviors, and the runtime setting applies changes immediately. Assisted-by: Codex:gpt-5 * fix(ui): expose gallery startup pre-warm The existing gallery autoload setting also gates the startup metadata warmer. Name both effects in Settings so operators can find the requested boot control.

Assisted-by: Codex:gpt-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * test: drop the static network lint in favour of real isolation The offline test suite already prevents tests from reaching the network twice over: run-test-linux-offline.sh puts the test process in a cgroup and REJECTs egress outside the private ranges, and HardenedTransport installs testnetwork.LocalGuard to refuse dials that resolve to a public address. Both fail the test with a precise error at the moment of the dial. test-network-lint.sh added neither. Its diff stage defaulted to a HEAD base, so on a clean checkout it compared the tree against itself and inspected nothing; the branch's own commits were never examined. It only produced output when an earlier job step dirtied the tree, and then it matched a bare https?:// against whatever changed. make react-ui runs npm install rather than npm ci, so CI rewrote core/http/react-ui/package-lock.json and the lint reported an npm registry URL as forbidden test network access: + "resolved": "https://registry.npmjs.org/hono/-/hono-4.12.25.tgz", Its fingerprint stage was self-defeating in a quieter way: hashing the whole tree's network-mechanism inventory meant every rebase onto a master that touched any _test.go needed a manual baseline bump, so the check mostly caught its own staleness. Remove the script, its make target and the two prerequisite edges, along with the test-network: fixture markers that existed only to suppress it. The isolation itself is untouched.

fix(gallery): repair DeepSeek V4 fallback (#11480)
The DeepSeek V4 Flash base entry points at a Hugging Face repository page instead of a GGUF object.

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. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * chore(llama-cpp): bump pin to 9de0fcf2b and drop the TTS codec mask Upstream fixed the Qwen3-TTS abort in ggml-org/llama.cpp c8e03ce81 ("mtmd/ggml: add ggml_build_forward_order", #26649), landed one hour after the previous pin. ggml_build_forward_expand marks a tensor and all its ancestors for compute, so using it as a pure ordering hint defeated ggml_build_forward_select and made GEN_WAV calls execute the GEN_CODE branch against a stale inp_code0, hitting the get_rows bound assert in ggml_compute_forward_get_rows. 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. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(llama-cpp): expose max_frames for TTS requests The Qwen3-TTS backbone does not always emit <|codec_eos_token|>, and when it does not, generation runs to upstream's 512-frame n_predict default. 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. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * build(llama-cpp): let unpatched forks opt out of the TTS task turboquant and bonsai copy grpc-server.cpp into llama.cpp forks that do not carry our patches. disable-tts-task.sh injects the same kind of preprocessor switch disable-score-task.sh already uses, so those builds answer UNIMPLEMENTED rather than failing to compile. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(config): keep a TTS speaker-encoder projector out of vision detection Task 1 exempted a declared-TTS model's mmproj from VisionSupported, but the first real gallery entry with an mmproj still came back vision-capable through two paths the earlier fix did not close. 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> * feat(gallery): add Qwen3-TTS entries for the llama-cpp backend Two entries over upstream's own GGUF conversion, Q8_0 and Q4_K_M, each pairing a backbone with the Q8_0 projector. Named to sit alongside the existing qwen3-tts-cpp entries rather than replace them. Also tags the llama-cpp backend text-to-speech / TTS so the backend browser surfaces the capability. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs: cover Qwen3-TTS on the llama-cpp backend Adds the gallery variants, the two-file mmproj configuration, the required voice reference, and the language and sampling knobs. Also corrects the streaming-support list, which named only voxcpm. 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. Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): declare what nemotron-3-nano-omni actually accepts The entry is backend: vllm-omni with known_usecases: [chat, completion], no mmproj and no media marker, so it used to report vision only through the blanket GuessUsecases fallthrough that the vision branch in this branch removed. 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.

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.

* 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.

* 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.

* 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.

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).

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.

feat(ui): replace the gallery and inventory tables with a rail and a detail pane (#11288)
* feat(ui): rename the Install Models nav entry to Discover "Install Models" named the action rather than the destination, and it was the only multi-word entry in a rail of one-word ones (Home, Chat, Studio, Talk, Build, Operate). 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. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * refactor(ui): extract the split view into shared components Discover shipped its rail, pane and detail header as private functions inside Models.jsx. 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. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * feat(ui): put the Host inventory on the split view The last of the three surfaces, and the one that is not a catalog. 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. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * polish(ui): accessibility and consistency pass over the three split views Findings from a pass over what the previous four commits actually shipped, rather than what they were supposed to. 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. The identity file ended up committed on this branch by a `git add -A` while verifying the gallery changes against a live instance. Anchored, so it matches the runtime directory at the repo root and not a `data` directory nested inside some package.

feat(audio-cpp): add the audio.cpp native backend (#11141)
* backend(audio-cpp): add the native build scaffold Links 0xShug0/audio.cpp engine_runtime through its public framework headers and serves Health/Status. 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. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): parse namespaced model options Splits option entries on the first colon so path values survive, and routes load./session. prefixes to the upstream load and session option maps. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): reject out-of-range numeric model options std::atoi is undefined once the digits exceed long and in practice wraps, so device:2147483648 was accepted and handed the ggml backend selector a device index of -2147483648 from a function whose error text promises a non-negative integer. 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. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): route LocalAI RPCs onto audio.cpp tasks Task-major resolution over the family's advertised capability set, with the voice-reference and instructions signals selecting cloning and voice design, and a streaming-to-offline fallback for server-streaming transcription only. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): use upstream's 'spk' task name and pin the preference order The SpeakerRecognition short name was 'spkrec', which audio.cpp neither prints nor parses; a name copied out of audio.cpp was rejected and a pinned 'spkrec' would not survive the engine boundary. 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): convert sample, time and PCM units Integer nanosecond conversion so 44.1 kHz stays exact, float seconds for the VAD and diarization messages, and saturating s16le encode so an overshooting sample cannot wrap to the opposite sign. 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.

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. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): stop linking sentencepiece's vendored protobuf engine_runtime links sentencepiece, whose default SPM_PROTOBUF_PROVIDER builds the protobuf-lite 3.14.0 sources it vendors. 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. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): serve the AudioTransform RPC Covers voice conversion, singing voice conversion, speech to speech and source separation, the four tasks LocalAI's AudioTransform can represent. 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. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): refuse an impossible stem early, and stop blaming the caller for a failed write Four fixes from the first review of the AudioTransform RPC. check_can_serve now returns the resolved route, so params[stem] on a route that is not source separation is refused from the route instead of after a full inference: 11 ms rather than the 4.5 s a miocodec conversion costs, and far worse on seed_vc or vevo2. 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. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): correct the vevo2 clause, and assert the absences Review found a false clause in the AudioToAudioStream refusal. 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. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): make the missing-switch-case diagnostic fatal unsupported_surface() switches UnsupportedRpc onto the table row that explains it, with no default label, so -Wswitch reports an enumerator nobody handled. 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. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): exempt the driver libraries from the packaging gate package.sh already left libcuda.so* and libnvidia-* to the host when copying, because the driver has to match the kernel module on whatever host runs the image, but the validation gate had no matching exemption. 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.

* feat(3d): add Generate3D RPC, FLAG_3D capability, and /v1/3d/generations endpoint Adds the plumbing for image-conditioned 3D asset generation (binary glTF / GLB output), modeled on the video generation path: - backend.proto: Generate3D RPC + Generate3DRequest (staged image src, glb dst, seed/step/cfg_scale/texture_steps, quality and background enums, params map for backend-specific extras) - pkg/grpc: thread Generate3D through client, server, embed, base and the backend interfaces; connection-evicting and distributed-node wrappers (in-flight tracking + file staging) included - core/config: FLAG_3D usecase (guessed only for the trellis2cpp backend), '3d' canonical usecase string mapped to the Generate3D method, and a '3d' output modality - REST: POST /v1/3d/generations (+ unversioned alias) returning OpenAIResponse with a /generated-3d URL or b64_json; conditioning image accepted as URL, base64, or data URI; quality/background validated at the edge; .glb served as model/gltf-binary - auth: '3d' route feature (default ON); /api/instructions entry Assisted-by: Claude:claude-fable-5 [Claude Code] Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(trellis2cpp): add the trellis2.cpp image-to-3D backend Wraps localai-org/trellis2cpp (C++/GGML port of Microsoft TRELLIS.2, pbr-textures branch) as a Go+purego backend, following the stablediffusion-ggml pattern: - backend/go/trellis2cpp: purego bindings to the flat C ABI (v9, asserted at startup), eager pipeline load with model-set validation (refuses non-trellis GGUFs; degrades coarse/geometry-only/textured exactly like the upstream demo), Generate3D via t2_generate + t2_bake_glb writing a binary glTF to dst. 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.

feat(backend): vllm-cpp - text-generation backend for vllm.cpp with llama.cpp-parity tool calling (#11100)
* feat(backend): add vllm-cpp text-generation backend (vllm.cpp) Wrap https://github.com/mudler/vllm.cpp - the LocalAI-team from-scratch C++20 port of vLLM (paged KV cache, continuous batching, prefix caching, safetensors + GGUF loading, no Python at inference) - as a Go gRPC backend over its stable C ABI (ABI v2) via purego. Backend (backend/go/vllm-cpp): - Load -> vllm_engine_load: accepts a .gguf file or a config.json model dir (anything else is refused, satisfying the greedy-probe rule); context_size maps to max_model_len, options block_size/num_blocks/max_num_seqs size the KV cache and scheduler admission. - Predict -> vllm_complete (blocking); PredictStream -> vllm_complete_stream with the per-delta C callback bridged into the gRPC stream. The backend embeds base.Base (not SingleThread): concurrent requests batch continuously in the engine's shared AsyncLLM scheduler. - PredictOptions.Grammar -> the ABI's structured_grammar (GBNF), giving grammar-constrained tool calling at parity with llama-cpp; the ABI also exposes JSON-schema/regex/choice constraints. - Hand-mirrored POD structs with layout locked by unit tests (unsafe.Offsetof vs the C offsets) and a runtime vllm_abi_version gate. - One portable library per platform (vllm.cpp uses per-file SIMD tiers with runtime dispatch), so no avx/avx2/avx512 variant builds. Wiring: - backend-matrix: CPU amd64+arm64 (per-arch + manifest merge), CUDA 12/13 amd64 (120a;121a Blackwell fat binary), L4T arm64 (121a, GB10/DGX Spark - the runtime-proven GPU target), Vulkan amd64, and Darwin arm64 Metal. - backend/index.yaml meta + 12 image entries (latest/development x cpu, cuda12, cuda13, l4t, vulkan, metal); bump_deps registration for the VLLM_CPP_VERSION pin; root Makefile registration; test-extra runs the unit specs (pure Go, no engine build). - Importers: preference-only swaps - llama-cpp (GGUF) and vllm (safetensors) advertise vllm-cpp via AdditionalBackends and emit backend: vllm-cpp without tokenizer templating (the C ABI takes the FINAL prompt; templating and tool parsing stay LocalAI-side). No auto-detect importer. - Docs: backends list, top-level README maintained-engines table, compatibility table. Verified: 20/20 Ginkgo specs against the real pinned engine and Qwen3.5-2B-UD-Q8_K_XL.gguf on CPU - blocking + streaming parity, greedy determinism, stop words, GBNF-constrained generation, and 4 concurrent streams; plus a dlopen/ABI-gate smoke of the built gRPC server binary. Upstream ABI v2 + production structured-output wiring landed as mudler/vllm.cpp@86013f3. Assisted-by: Claude Code:claude-fable-5 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(vllm-cpp): ride the autoparser code path - engine-side chat templating and tool engagement (ABI v3) The backend now implements AIModelRich (PredictRich / PredictStreamRich) over vllm.cpp's ABI v3 chat entry points, so chat and tool calling ride the SAME code path as the llama.cpp autoparser: the ENGINE renders the model's chat template, decides when a tool call engages, and parses it - LocalAI receives pre-parsed ChatDelta / ToolCallDelta protos exactly as it does from llama-cpp. - With use_tokenizer_template + structured Messages, PredictOptions lowers to ONE OpenAI chat request JSON (messages, tools, tool_choice, sampling, stream_options.include_usage) for vllm_chat / vllm_chat_stream. tool_choice auto lowers engine-side to a LAZY structural-tag decode constraint - free text until the model emits the tool trigger, then the call is grammar-constrained; required/named force a call. Tool output is parsed by the engine's streaming Hermes-style parser; each chat.completion.chunk maps onto ChatDeltas (content / reasoning_content / tool_calls) which the host already prefers over Go-side tag extraction. Without structured messages the plain path (LocalAI templating + optional GBNF grammar) applies unchanged. - The engine resolves the chat template from the GGUF tokenizer.chat_template metadata (or tokenizer_config.json); templates beyond its minja subset - e.g. the full Qwen3.5 namespace()/macro template - degrade engine-side to a Hermes-aware fallback prompt (tools schemas + <tool_call> instruction) with a stderr witness, so structural-tag engagement keeps working. - Importers now emit the same config shape as llama-cpp for vllm-cpp (use_tokenizer_template: true, no-grammar autoparser flow); only the llama-cpp-specific use_jinja option and the vllm-python parser options are dropped. - Pin bumped to mudler/vllm.cpp@aaed7ec (ABI v3 + chat-prompt resolution). Verified against the real engine and Qwen3.5-2B-UD-Q8_K_XL.gguf on CPU: full suite green - blocking chat, streaming deltas concatenating byte-equal to the blocking answer, a REQUIRED tool call returning schema-valid arguments JSON, and an AUTO run where the engine itself engages get_weather and streams parsed tool deltas; plus unit specs for the request lowering, chunk->ChatDelta mapping, and the C struct mirrors (ABI gate now v3). Assisted-by: Claude Code:claude-fable-5 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(vllm-cpp): ABI v5 - engine-side parser selection for 30 tool dialects + reasoning Bump the vllm.cpp pin to the autoparser-parity engine: 30 tool-call dialects (every pure-text parser in the pinned vLLM registry, each ported 1:1 with its upstream tests), 7 reasoning parsers, google/minja as the template renderer (the full Qwen3.5 template now renders engine-side), per-family structural tags (tool_choice required/named compiles the model's NATIVE syntax where expressible), and template auto-detection for both parser axes. Backend changes: - cModelParams mirrors ABI v5 (tool_parser + reasoning_parser fields, layout-locked by the offset tests; ABI gate now v5). - New model options tool_parser:<name> / reasoning_parser:<name> pass through to the engine; unset means template auto-detection (18-row tool marker table; [THINK]->mistral, <think>->think_auto for reasoning); "none" disables the reasoning split; unknown names fail the first chat call. - Chat chunks parse the `reasoning` field (the pin renamed reasoning_content), flowing into ChatDelta.ReasoningContent which the host already prefers. Live e2e against Qwen3.5-2B-UD-Q8_K_XL.gguf on CPU, full suite green: the real chat template renders (no more fallback), reasoning auto-detection picks think_auto so markerless answers stay pure content (the live run caught the deepseek_r1 content-swallow upstream and drove the think_auto fix), required tool_choice returns schema-valid arguments, auto tool_choice engages engine-side and streams parsed deltas, and blocking/streaming stay byte-identical. Turn latency also dropped (proper template EOS behavior). Upstream program landed as mudler/vllm.cpp 86013f3..5fffe7e (ABI v2-v5, minja, parser waves B1/B2/B4, reasoning seam, structural-tag registry, think_auto). Assisted-by: Claude Code:claude-fable-5 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * chore(vllm-cpp): bump the engine pin to the ENG-wave close-out mudler/vllm.cpp@df8909b: the six engine-backed vLLM tool-parser families (qwen3-coder/xml/mimo, kimi_k2, glm45/47, minimax_m2, gemma4, seed_oss) text-reimplemented from their wire formats and held to the upstream test suites - 39 registered dialects; the pinned vLLM registry is now covered except the three Rust/Harmony-backed families, descoped by decision. kimi_k2 also gains a full native structural-tag builder; four new template auto-detection rows land with test-pinned ordering. Full backend e2e re-run green against Qwen3.5-2B-UD-Q8_K_XL.gguf on CPU. Assisted-by: Claude Code:claude-fable-5 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(vllm-cpp): add the vllm-cpp-development gallery meta The gallery grew the twelve latest/development image entries but was missing the separate vllm-cpp-development meta (own capabilities map targeting the -development image names), which every backend ships so the development gallery resolves per-platform. Validated: all capability targets in both metas resolve to existing entries, and every image URI's tag suffix matches a backend-matrix build. Also full-stack verified in this change's context (single-node local-ai from this branch, locally-built backend under --backends-path, Qwen3.5-2B GGUF): /v1/chat/completions non-stream (clean content + usage), streaming (SSE deltas), tool_choice auto engaging get_weather engine-side with schema-valid arguments and finish_reason=tool_calls, and streamed tool-call deltas in the standard name-first cadence. Assisted-by: Claude Code:claude-fable-5 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(vllm-cpp): repair the CI backend builds - gcc-14 -Werror + fat-arch Triton Two distinct failures took down all five vllm-cpp backend builds on the PR: 1. gcc-14 (ubuntu:24.04 CI images; the local toolchain is gcc-13) fails the engine build with -Werror=maybe-uninitialized in InputBatch::condense - a false positive through a staging std::optional's raw storage. Fixed upstream (mudler/vllm.cpp@61f3e85) by moving slot-to-slot directly; verified BOTH ways under dockerized g++-14.2 (unfixed reproduces CI's two diagnostics exactly, fixed compiles clean) with the engine's behavior suites green. Pin bumped to that sha. 2. The amd64 CUDA builds died at CMake configure: the vendored Triton-AOT cubin trees are per-arch and the engine refuses -DVLLM_CPP_TRITON=ON on a multi-arch (120a;121a) fat build unless pinned to one tree, which would be unsound for the other arch. Triton is now enabled only on the single-arch arm64/GB10 build (where the cubins matter); the fat amd64 binary uses the engine's non-AOT GDN path. Backend e2e re-run green at the new pin (Qwen3.5-2B on CPU, full suite). Assisted-by: Claude Code:claude-fable-5 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(vllm-cpp): cuda-12 images cannot compile compute_121a - target 120a only The second CI round surfaced a CUDA-version constraint: the cuda-12 (12.8) image's nvcc rejects 'compute_121a' (GB10 arch support landed with CUDA 13), killing the amd64 cuda-12 build at nvcc. Gate the architecture list on CUDA_MAJOR_VERSION (exported by Dockerfile.golang): cuda-12 builds consumer Blackwell 120a only, cuda-13 keeps the 120a;121a fat binary, arm64/l4t (cuda-13) keeps single-arch 121a with the Triton cubins. GB10 is arm64, so the amd64 cuda-12 image never served it - no capability change. Verified by Makefile dry-run variable dumps for all three combinations (cuda12 -> 120a; cuda13 -> 120a;121a; cpu -> CUDA off). Assisted-by: Claude Code:claude-fable-5 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(vllm-cpp): drop the cuda-12 variant - the engine needs the CUDA 13 toolchain Third CI round, third layer: with the arch list already narrowed to 120a, the cuda-12 (12.8) build still dies in ptxas compiling the sm_120a NVFP4 MMA kernels ("Vector type too large, exceeds 128 bit limit") - the Blackwell fp4 path genuinely requires the CUDA 13 toolchain, and vllm.cpp supports Blackwell-family GPUs only. Shipping a cuda-12 image without the fp4 kernels would be a crippled build of an engine whose whole GPU story is fp4, so the variant is dropped instead: - backend-matrix: cuda-12 vllm-cpp entry removed (cuda-13 amd64, l4t arm64, cpu, vulkan, metal remain). - gallery: cuda12 image entries removed; the nvidia capability now resolves to the cuda13 image in both metas; the nvidia-cuda-12 key is dropped so older-driver hosts fall back to the CPU image instead of an unrunnable one. - backend Makefile: BUILD_TYPE=cublas under CUDA_MAJOR_VERSION=12 now fails fast with a clear message; cuda-13 keeps the 120a;121a fat binary and arm64/l4t keeps 121a with the Triton cubins. Verified: Makefile branch dumps for all four combinations (cuda12 loud error, cuda13 fat, arm64 121a+Triton, cpu off), YAML parses, matrix filter tests green, gallery capability targets all resolve. Assisted-by: Claude Code:claude-fable-5 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(vllm-cpp): forward multi-turn tool identity and reasoning to the engine chatRequestJSON dropped Message.ToolCallId and Message.Name on role="tool" replies and Message.ReasoningContent on assistant history, so a second turn after tool execution reached the engine's chat template without the fields that bind a tool result to the call it answers. Forward all three (present-only, matching the OpenAI wire shape) and pin vllm.cpp to 6a0bd3e7, where ChatMessage parses/round-trips tool_calls, tool_call_id, name and reasoning and the minja adapter exposes them to the template context. Adds the round-trip request-lowering spec (user -> assistant tool_call -> tool reply -> lowered request) and re-ran the gated e2e suite against the new engine pin with a real Qwen3.5 GGUF: chat, reasoning split, streaming parity, required-tool and auto-tool cases all green.

Gated e2e suite re-run green against the new pin with a real Qwen3.5 GGUF.

Use the same portable fallback chain as the other darwin backends: nproc, then sysctl hw.ncpu, then 4.

fix(upgrade-check): don't filter upgrade candidates by controller capability (#11024)
CheckUpgradesAgainst resolved gallery entries through AvailableBackends, which drops every entry the *local* host cannot run. In distributed mode the host running the check is a CPU-only controller while the GPU backends live on worker nodes, so FindGalleryElement returned nil for every cuda/rocm/l4t entry and those backends were silently skipped. Measured on a live cluster: GET /backends reported 48 installed backends, POST /backends/upgrades/check evaluated 5 — all of them plain or cpu-prefixed. The 43 skipped were all hardware-specific builds. As a result cuda13-nvidia-l4t-arm64-longcat-video-development stayed at sha256:0b8dc851 while the registry tag held sha256:38dae6ff, and a cuDNN packaging fix sat unnoticed on a GPU worker for two days. Every name looked up here is already installed somewhere in the cluster, so hardware compatibility was decided at install time; re-deciding it against the controller is wrong. Switch both CheckUpgradesAgainst and UpgradeBackend to AvailableBackendsUnfiltered.

gallery: remove duplicated entries and lint against them recurring (#10996)
gallery: remove duplicated entries and lint against them coming back gallery/index.yaml declared eight names twice: deepseek-r1-distill-llama-8b, llama3.2-3b-enigma, qwen3-asr-0.6b, qwen3-asr-1.7b, qwopus-glm-18b-merged, voice-en-us-kathleen-low, whisper-large-q5_0 and whisper-small-q5_1. FindGalleryElement resolves a reference by returning the first match, so in every pair the second copy was unreachable: it could not be installed, could not be selected as a variant target, and could not be corrected, because any edit to it went to a copy nobody reads. A reference to such a name is also ambiguous to anything reasoning over the catalog, which is why the variant proposal job refuses to propose against them. Each pair was compared both as parsed entries and as raw text, and all eight were byte-identical apart from position. None of the sixteen blocks defines a YAML anchor or pulls one in with a merge key, so nothing was reachable only through a deleted block, and no entry named a removed copy as a variant target. Removing the second copy of each therefore changes no behaviour: the parsed set loses exactly eight entries and every surviving entry is field-for-field unchanged. The removal is textual, by line range, so the diff is pure deletions rather than a reflow of forty thousand lines. checkNoDuplicateEntryNames is the rule that keeps them out, added beside the existing gallery invariants and reporting in the same style. checkSingleVariantClaim closes the adjacent gap in the same place. VariantParents resolves a build claimed by two parents by taking the first in gallery order and calls that deterministic "for a gallery the linter would reject", but nothing rejected it: the invariant was held by curation alone. Now it is a rule, and the comment describes something real. No target is doubly claimed today, so the rule is green on arrival.

fix(modelartifacts): treat CIFS EACCES as lock contention, not failure (#10986)
flock(2) on CIFS/SMB returns EACCES when another client holds the lock: the kernel maps STATUS_LOCK_NOT_GRANTED and STATUS_FILE_LOCK_CONFLICT to -EACCES and never produces EWOULDBLOCK on that path. gofrs/flock only recognises EWOULDBLOCK as contention, so TryLockContext returned a bare "permission denied" and Ensure aborted. Both replicas then fell back to legacy loading, which makes the worker download the whole repo in-band inside LoadModel and blow the remote-load deadline. Replace TryLockContext with an explicit wait loop over a new Locker interface, classifying EWOULDBLOCK/EAGAIN/EACCES/EBUSY as contention. EACCES is ambiguous at the syscall boundary but not here: the lock file is already open O_CREATE|O_RDWR, so a real permission problem would have failed the open with an *fs.PathError, and flock(2) documents no EACCES on Linux at all. The wait is bounded (DefaultLockWait, overridable via WithLockWait), so even a misclassification degrades to a delay. On timeout the committed result is re-checked before reporting the new ErrLockContended, so a peer that finished the work still wins. Locker also exists so the contention path is testable without a network filesystem: nothing in CI can make flock(2) return EACCES on demand. Raise the fallback to error for a managedArtifactBackends backend, via a shared config.LogArtifactFallback used by both call sites. For those backends the legacy path is not graceful degradation, and the operator otherwise sees only a timeout with no causal link. The fallback stays non-fatal. Drop the os.Chmod(layout.Lock, 0o600) after acquisition: flock.New already creates the file 0600, and the chmod was gratuitous risk on a nounix mount that ignores modes.

feat(gallery): let one gallery entry offer several builds of the same model (#10943)
* feat(system): expose raw detected capability for model meta resolution Model meta gallery entries express hardware fallback through candidate ordering rather than a capability map, so they need the undecorated detected capability string without Capability's default/cpu fallback chain. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * refactor(system): drop duplicate capability accessor, cover DetectedCapability ReportedCapability was added with a body identical to the existing DetectedCapability. Keep one accessor and move the specs onto it, since DetectedCapability had no direct coverage of its no-fallback behavior. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(vram): parse IEC binary size suffixes (KiB..PiB) ParseSizeString accepted only SI suffixes, so a "20GiB" floor was rejected outright. Model and VRAM sizes are conventionally quoted in IEC units, and silently reading GiB as GB would understate a floor by about 7%. Purely additive: these inputs previously returned an unknown-suffix error. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): add Candidate type for meta model entries Candidate is one option in a meta entry's ordered variant list. It names a concrete gallery entry and declares when that entry suits the host. EffectiveMinVRAM resolves the VRAM floor, letting an authored min_vram win over a nightly-inferred one. An unparseable floor errors instead of being treated as absent: swallowing a typo would turn a constrained candidate into an unconstrained one and select a too-large variant rather than fail loudly.

Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): resolve meta model entries to hardware-appropriate variants at install Meta gallery entries carry an ordered candidate list; at install time the first candidate the host satisfies is resolved and its payload installed under the meta's name, so the model keeps a stable name regardless of which variant backs it. The resolution is recorded in the installed gallery config so a reinstall honors a prior pin and operators can see the backing variant. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): key meta pin recall on the installed name and detach resolved entries Six review findings on the meta-entry install path. Pin recall was keyed on the gallery entry name while applyModel writes the record under the install name (req.Name when supplied), so a meta installed under a custom name with a pin lost that pin on reinstall and was silently re-resolved onto a different variant, possibly swapping its backend. Compute the install name with applyModel's own precedence before the recall. ResolveMetaModel returned a shallow struct copy, so the resolved entry's Overrides aliased the gallery entry's map and the install path's in-place mergo merge wrote the caller's request into the shared catalog. Detach Overrides, ConfigFile, AdditionalFiles, URLs and Tags. Not exploitable today only because this path re-unmarshals the gallery per call, which is a property nobody should have to rely on. Also: overlay the meta's name onto the persisted config for meta installs so the gallery file no longer records the variant's name; move the pinned-VRAM warning below the variant validation so a pin naming a nonexistent entry does not warn about VRAM before failing for an unrelated reason; and stop seeding config.URLs in the config_file branch, which duplicated every declared URL. Add seven network-free specs driving InstallModelFromGallery with a meta entry: variant payload wins over the meta's legacy url fallback, the resolution record round-trips to disk, a pin is recorded and honored on reinstall including under a custom install name, and the resolved entry does not alias the gallery's maps. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): deep-copy meta overrides and make two specs functional ResolveMetaModel detached the resolved entry's Overrides and ConfigFile with maps.Clone, which only copies the top level. Gallery overrides are nested in practice (parameters.model is near-universal) and the install path merges the caller's request with mergo.WithOverride, which recurses into nested maps and overwrites them in place, so the gallery entry's own inner maps were still reachable and still got rewritten by the last caller to install. Copy both maps all the way down instead, recursing through the container shapes a YAML decoder produces. ConfigFile is not mutated on the install path today, but it carries the same kind of nested payload and leaving it shallowly cloned would invite the bug back. Also fix two specs that passed whether or not their target fix was present: - "does not write the caller's overrides back into the gallery entry" re-read the catalog from disk, which re-unmarshals fresh structs and so cannot observe in-memory aliasing. It now asserts against the in-memory gallery entry and drives the real mergo merge. - "round-trips the resolution record to disk under the meta's name" asserted a name that is already correct in the config_file branch. It now drives the url branch via a file:// fixture, where the meta-name overlay actually applies. Both were verified red by reverting their fix. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(gallery): lint meta model entry invariants in index.yaml Adds Ginkgo specs that parse the shipped gallery/index.yaml and enforce the invariants that keep meta entries safe: a legacy url fallback equal to the final candidate's url, references only to existing non-meta entries, a min_vram floor on every candidate but the last-resort one, a capability drawn only from the vocabulary the system can report, and descending VRAM floors within a capability group. The capability check is the only compensating control for a typo there. Candidate matching is a case-sensitive exact comparison against SystemState.DetectedCapability(), so an unknown value never matches and falls through silently instead of erroring. The vocabulary therefore mirrors the raw return set of getSystemCapabilities(), which notably excludes "cpu": that is a fallback key inside Capability(capMap) on the meta backend path, never a reported capability. A CPU-only host reports "default". These pass vacuously until the pilot meta entry lands; the guard is intentionally in place before the thing it guards. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(gallery): close coverage gaps in the meta entry lint The ordering invariant grouped candidates by capability and asserted floors descend within a group. A candidate with an EMPTY capability matches every host, so it does not belong in its own group: it dominates every later candidate whose floor is at or above its own, across capability groups. Track a running minimum floor over the unconditional candidates instead, which subsumes the old same-group check for the empty capability. Every spec skipped non-meta entries, so with zero meta entries in the index all five bodies were no-ops. Aligning GalleryModel.IsMeta() with GalleryBackend.IsMeta(), whose semantics are deliberately opposite, would have made all of them pass while checking nothing. Extract each invariant into a helper over a slice of entries returning the violations it finds, and cover those helpers with synthetic fixtures so the logic stays tested at zero meta entries. The index-driven specs are now a thin application of already proven logic. Also assert the index parses non-empty, report every violation in one run rather than aborting on the first, and parse the index once for the suite. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * ci(gallery): add nightly denormalization of meta model candidates Fills the read-only backend, quantization and inferred_min_vram fields on meta gallery candidates and opens a PR, modeled on the existing checksum_checker job. Computing these needs network access, so it happens nightly rather than at install time. An authored min_vram is never modified: a human who measured a real load knows more than a pre-download estimate does. The index is rewritten via yaml.Node rather than a document round-trip. A full round-trip reflows all ~26k lines of gallery/index.yaml, which would bury the computed values and make the nightly PR unreviewable. The rewrite touches only the three derived keys, so authored styling survives and a run that computes nothing leaves the file untouched. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ci): keep the gallery denormalize diff reviewable and self-healing The nightly denormalization job edits YAML nodes instead of round-tripping structs so its PR stays small enough for a human to review, but the write path undid that: yaml.Marshal re-encoded the node tree at yaml.v3's default 4-space indent and dropped the leading document marker, reflowing roughly 6000 lines around the handful of real changes. Encode through yaml.NewEncoder at the index's authored 2-space indent and restore the header. A write that changes three fields now changes three lines. Stale inferred_min_vram values were also never cleared. Both skip paths (an authored min_vram is present, or the candidate is the last resort) returned before touching the field, so a candidate that gained a floor or became the last resort after a reorder kept an inferred value that EffectiveMinVRAM reported as a real constraint, failing the meta lint with no way for the job to self-heal. Clear the field before both skips. The workflow discarded a whole night's work on any single failure: the program exits 1 when a candidate cannot be estimated, which aborted the job before the PR step, so one unreachable candidate blocked every other refresh indefinitely. Capture the status, open the PR with what was computed, mark the PR body as partial, and fail the run afterwards so the problem still surfaces. Also preserve the index's existing file mode instead of forcing 0644, and drop the redundant //go:build ignore tag, since Go already skips dot directories and the sibling modelslist.go carries no tag. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): add nanbeige4.1-3b meta entry with hardware-resolved variants Adds the first real meta entry to the gallery index. It resolves to the Q8_0 build on hosts with at least 6GiB of VRAM and to the Q4_K_M build everywhere else, installing either payload under the stable name nanbeige4.1-3b. The entry carries a url equal to its final candidate's url. LocalAI releases that predate candidates support parse the index non-strictly and drop the key silently, so without that url they would list the entry and install nothing. A regression spec parses the index the way those releases do and asserts every meta entry stays installable for them. Also teaches core/schema/gallery-model.schema.json about candidates. The schema sets additionalProperties: false at the top level, so an author following CONTRIBUTING.md and adding the yaml-language-server comment would otherwise get a validation error on this entry. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): make candidate entries complete, installable entries Reworks hardware-resolved gallery variants after a design pivot. There is no longer a separate "meta" entry kind. A gallery entry is a normal, complete entry that may additionally carry candidates:, a list of hardware-gated upgrades over itself, and the entry is itself the last-resort candidate. The previous design relied on a bare url: as the fallback for LocalAI releases that predate candidates support. That fallback is empty in practice: none of the 80 gallery/*.yaml files carry a top-level files:, and 1216 of 1281 index entries carry their payload in the index entry itself, so a url alone yields a config template with nothing to download. Since every released LocalAI reads gallery/index.yaml live from master, merging a payload-less entry would have shown every existing user a model that installs to a broken state. Making the entry its own base candidate removes the problem at the root: old clients drop the candidates key and install the entry exactly as they do today. Resolution order is now explicit pin, then capability plus VRAM over the declared upgrades, then the entry itself. The entry ALWAYS installs: when its own min_vram or capability is unmet the installer warns and installs it anyway, because there is nothing below it and refusing would make the gallery behave worse the newer the client is. A pin naming the entry's own name is valid and is how an operator declines an upgrade. IsMeta() becomes HasCandidates(), ResolveMetaModel becomes ResolveVariant, and the persisted meta_name record key becomes entry_name. GalleryBackend.IsMeta() is a separate concept and is untouched. The lint drops the three rules the pivot makes wrong (url equality with the final candidate, no inline payload, unconstrained final candidate) and gains one: the entry's own floor must sit strictly below every candidate's, since a base that outranks a candidate makes that candidate unreachable. The pilot entry is now the existing nanbeige4.1-3b-q4, which gains a 2GiB floor of its own and a single 6GiB upgrade to nanbeige4.1-3b-q8, replacing the separate nanbeige4.1-3b entry added in |

fix(model-artifacts): materialize longcat-video on the controller, and support companion repos (#10949)
* fix(model-artifacts): materialize longcat-video checkpoints on the controller longcat-video loads a checkpoint directory: its backend.py takes request.ModelFile when os.path.isdir(request.ModelFile) and otherwise falls back to snapshot_download. That places it in the same class as transformers/vllm/diffusers/sglang, but the allow-list added in #10910 did not enumerate it, so PrimaryArtifactSpec returned no managed artifact for a bare HuggingFace repo id. The consequence in distributed mode: nothing was acquired on the controller, ModelFileName fell through to the raw repo id, and staging skipped the resulting phantom /models/<owner>/<repo> path. The worker received a blank ModelFile, fell back to request.Model, and downloaded ~83GB from HuggingFace inside the remote LoadModel deadline - so the load could only ever fail with DeadlineExceeded while an abandoned backend process kept downloading. Note this materializes the full repository. The backend restricts its own snapshot_download with allow_patterns, and the avatar repo ships both base_model/ and base_model_int8/ where only one is ever loaded; inferred specs have no way to carry patterns today. Tracked separately. Assisted-by: Claude:opus-4.8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed): warn when staging skips a non-existent model path stageModelFiles logs "Staging model files for remote node" up front, then silently drops any path field that does not exist on the controller. The skip itself is legitimate and must stay: a backend outside managedArtifactBackends that takes a bare HuggingFace repo id gets an optimistically constructed path (ModelFileName falls through to the raw model reference) that was never materialized, and sources its own weights on the worker. Erroring would break those configs. But at debug level the operator is left with a reassuring staging line and no trace of the skip, so a genuine controller-side acquisition gap is indistinguishable from a healthy pass-through - it surfaces much later as a remote LoadModel timeout, on a worker that is quietly downloading tens of gigabytes. Raise the skip to warn and name the field, path, node and tracking key. Behavior is unchanged. Assisted-by: Claude:opus-4.8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(model-artifacts): allow a config to declare companion artifacts A composed pipeline needs more than one HuggingFace snapshot. LongCat-Video-Avatar-1.5 loads its own transformer but takes the tokenizer, text encoder and VAE from the separate LongCat-Video base repo, so a single-artifact config cannot express it and the backend is left to fetch the second repo itself at load time. Widen the artifact model to target: model plus any number of named target: companion entries. Normalize accepts the new target and constrains a companion name to [a-z0-9][a-z0-9_-]{0,63} because that name is the option key the backend later receives; a companion may not claim primary_file, which only means anything for a load target. ModelConfig.Validate requires exactly one primary and requires it first, since Artifacts[0] is what ModelFileName, size estimation and staging all resolve from. Both acquisition paths now loop instead of touching index 0 alone: preloadOne for an already-installed config, bindPrimaryArtifact for a gallery install. Failure policy differs by provenance. An inferred primary keeps its warn-and-fall-back, because the legacy download path still exists for it. Companions are explicit by construction, so they are all-or-nothing: a config naming one is asserting the backend needs it, and failing at the acquisition boundary is far more legible than a missing-weights error surfacing later inside the backend. The cache key is deliberately unchanged. It hashes source identity only, never name or target, so every already-installed managed model still hits its existing snapshot instead of silently re-downloading. Two specs pin that: one proving a companion and a primary with identical sources agree on the key, and one pinning the digest of a known primary outright. Assisted-by: Claude:opus-4.8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(model-artifacts): hand resolved companion snapshots to the backend A materialized companion is useless until the backend can find it, and its location is a content-addressed cache key that does not exist until the artifact resolves. A static gallery override cannot carry that, and persisting it into the config YAML would rot the moment a re-resolve produced a new key. Synthesize it instead at load time: each resolved companion becomes "<artifact name>:<snapshot path>" in ModelOptions.Options, reusing the key:value convention backends already parse for options like attention_backend. The value stays relative to the models directory so a remote worker can resolve it under its own ModelPath once staging has rewritten the model root. An option the author set explicitly always wins, so pinning a companion to a local checkout still beats the managed snapshot. longcat-video resolves base_model through ModelPath, the same convention qwen-tts, voxcpm, outetts and ace-step already use for companion assets. Its sibling-directory heuristic is deleted: it looked for a LongCat-Video directory next to the model, which cannot exist under the content addressed .artifacts/huggingface/<key>/snapshot layout, so it was dead code the moment the model became managed. The gallery entry declares both repositories and restricts each with allow_patterns. The avatar repo ships base_model/ and base_model_int8/ and only ever loads one, so fetching the whole repo would roughly double the download. The patterns match the entry's own options (use_distill true, use_int8 default false); enabling use_int8 here also requires adding base_model_int8/**, which is called out in the entry. Assisted-by: Claude:opus-4.8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed): stage managed artifact trees from the models root Staging anchored the worker's models directory on the primary snapshot whenever a model was managed, so a companion snapshot could not reach the worker at all. frontendModelsDir was derived by stripping the Model relative path off the end of ModelFile. For a managed artifact nothing matches: ModelFile is .artifacts/huggingface/<key>/snapshot while Model stays a bare HuggingFace repo id, so the strip was a no-op and the "models directory" came out as the snapshot itself. Two consequences, both silent. Staging keys lost the .artifacts/huggingface/<key>/snapshot prefix, so two snapshots of one model were indistinguishable on the worker. And a companion, which lives in a sibling snapshot directory outside the primary, fell outside that directory entirely: StagingKeyMapper.Key collapsed its files to bare basenames and resolveOptionPath could not resolve the relative option at all, so it was skipped without a word. Derive the models root from the artifact tree instead when the path runs through it, and compute the worker's ModelPath from the file's path relative to that root rather than from the Model field. The legacy layout is unaffected: where Model really is the relative path, the new derivation reduces to the old one, which a regression spec pins. This deliberately changes an invariant that router_dirstage_test.go pinned: for a managed primary, ModelFile and ModelPath were both the snapshot directory, and staging keys were relative to it. Now ModelFile is the snapshot, ModelPath is the models root above it, and keys keep the full relative path. That spec is updated rather than accommodated, with the reasoning recorded inline, because the old invariant is exactly what made a sibling companion unreachable.

fix(distributed): backend discovery hid GPU-only backends behind the controller's capability (#10947)
* fix(backends): list backends runnable on worker nodes in distributed mode GET /backends/available filtered the gallery against the system state of the host serving the request. In a distributed deployment that host is the controller, which typically has no GPU, while the GPUs live on worker nodes. Any meta backend whose capabilities map lacks a "default" (or "cpu") key was therefore dropped from the listing entirely — longcat-video, vllm-omni, ltx-video, parakeet, edgetam and qwentts were invisible in the UI even though installing them by name on a GPU worker worked fine. Workers now report their own meta-backend capability at registration and the controller persists it on the node row. The controller cannot derive it: OS-dependent capabilities (metal, darwin-x86, nvidia-l4t) and the CUDA runtime refinements are only observable on the worker. Nodes registered before this field existed fall back to a coarse capability derived from their GPU vendor and VRAM. Backend discovery then evaluates compatibility as the union over healthy backend nodes, so a backend runnable on any node is offered while one no node can run stays hidden. Each remote capability is evaluated through a capability-pinned system state, otherwise a forced capability on the controller image (LOCALAI_FORCE_META_BACKEND_CAPABILITY or /run/localai/capability) would silently override every worker's verdict. With no registered nodes the listing is byte-for-byte what it was, so single-node deployments are unaffected. Also fixes the same-root-cause misclassification in /api/operations, which used the capability-filtered listing to decide whether an operation was a backend or a model install. A GPU-only backend installing on a worker is still a backend operation on the controller, so that lookup is now unfiltered.

fix(model-artifacts): gate inferred artifact materialization by backend (#10910)
The managed-artifact materializer stages a HuggingFace snapshot into a directory (.artifacts/huggingface/<key>/snapshot/). That is the right load target for directory-consuming backends (transformers, vLLM, diffusers, ...), but PrimaryArtifactSpec inferred a managed artifact from ANY HuggingFace-shaped model reference regardless of backend. A single-file backend such as llama.cpp or whisper was therefore handed the snapshot directory instead of the weight file and failed to load it. The /import-model importer already guards this with a backend allow-list (managedArtifactBackends), but the loader-side inference did not. Move the allow-list into core/config as IsManagedArtifactBackend and apply it in PrimaryArtifactSpec: only directory-consuming backends may have an artifact inferred from a bare reference; every other backend stays on the legacy download-to-file path. An explicit artifacts: block still bypasses the gate, where single-file snapshot resolution handles the load path. The importer now shares the same predicate, so both paths agree on which backends auto-materialize.

fix(gallery): make backend (re)install a clean replace instead of an overlay (#10726)
InstallBackend extracted the artifact directly into the target directory with no pre-clean, so a reinstall overlaid the new files onto the old ones. Files present in a previous version but absent in the new artifact (a stale .so, an orphaned package dir) survived and could shadow the new build at import time -- e.g. an old vllm shared object lingering next to a freshly pulled one. Only a failed download cleaned the directory. Stage the download/extraction into a `<name>.install-tmp` dir, validate run.sh is present, write metadata, then atomically swap it into place (rename current -> .install-backup, staging -> current, drop backup), rolling back on failure. This mirrors the atomic swap UpgradeBackend already performs, so install and upgrade now leave identical on-disk state with no orphaned files. Reported as part of #10720.

fix(gallery): block SSRF in gallery config URL fetch (#10665) (#10673)
POST /models/apply with an empty "id" fetches the attacker-supplied "url" gallery config directly via http.Client, with no check that the URL resolves to a public IP. In the default Docker deployment no API key is configured, so any network-reachable client can coerce LocalAI into issuing requests to internal services or cloud-metadata endpoints (and exfiltrate a small slice of the response through the job error message). Guard the config fetch chokepoints (GetGalleryConfigFromURL and GetGalleryConfigFromURLWithContext, which back both the /models/apply worker and gallery installs) with utils.ValidateExternalURL, matching the protection already applied to the CORS proxy and image/video/audio download paths. Only plain http(s) URLs are validated; non-network schemes (huggingface://, github:, oci://, ollama://, file://) resolve to fixed public services or local files and are left untouched.

fix(import): strip file:// scheme from model path for local imports (#10599)
Importing a model from a local directory (e.g. a HuggingFace checkout or an LM Studio store) via a file:// URI produced a config whose model field kept the scheme verbatim, e.g. model: file:///Users/u/.../Qwen3-4bit. The mlx and vllm backends treat that field as a HuggingFace repo id or local path and reject the file:// form with "Repo id must be in the form 'repo_name' or 'namespace/repo_name'", so the model imported fine but failed to load (issue #7461). Add a shared LocalModelPath helper that reduces a file:// URI to the bare filesystem path it points at and leaves HuggingFace/HTTP URIs untouched, and route the mlx, vllm, transformers and diffusers importers (all of which pass details.URI straight into the model field for from_pretrained-style loading) through it. Cover the helper directly plus end-to-end file:// import specs for the mlx and vllm importers.

fix(import): derive model name from selected GGUF for repo-root URIs (#10589)
When importing a HuggingFace GGUF model from a repository-root URI (no file component, e.g. hf://owner/repo) with the Model Name field left blank, the importer named the model after the repository (filepath.Base(details.URI)) instead of the GGUF file it actually selected from the repo listing (issue #10587). Track whether the user supplied an explicit name; the URI base is now only a fallback. In the HuggingFace branch, once the model group is picked, re-derive the name from the selected GGUF via a new modelNameFromShardGroup helper that uses ShardGroup.Base minus the .gguf extension. For sharded models this yields a clean logical name (e.g. Qwen3-30B-A3B-Q4_K_M) rather than a shard filename like ...-00001-of-00002. An explicit name preference still always wins, and the .gguf/URL/OCI paths are unchanged. Add network-free unit specs covering name-from-GGUF, clean-name-from-shard-base, and explicit-name precedence, and update the live integration specs that had encoded the previous repo-name behaviour.

pickPreferredGroup matched a quant preference against the shard base filename with strings.Contains. Because `f16` is a substring of `bf16`, asking for the `F16` mmproj quant would wrongly satisfy a `BF16` file and select it when its group came first.

feat(pii): NER tier engine — privacy-filter.cpp backend + NER-centric PII filter (#10360)
Squashed feat/pii-ner-tier-engine rebased onto master (was 45 commits; see backup/pii-ner-tier-engine-prerebase). Net change: - privacy-filter.cpp: standalone GGML engine for the openai-privacy-filter PII/NER token classifier, wired as a LocalAI gRPC backend (CPU/CUDA/Vulkan). TokenClassify moves off the patched llama.cpp path onto this backend. - PII filter reworked to be NER-centric (encoder/NER detection tier scanning whole conversations as one document), with a recreated bounded restricted- regex secret-matching pattern detector tier alongside it (per-model pii_detection.builtins / .patterns + core/services/routing/piipattern). - Detection labelled by source (ner vs pattern); backend trace / confidence / debug observability; analyze/redact exposed as a synchronous API. - Instance-wide default detector policy + per-usecase default-on; request filtering extended to completions, embeddings, edits & Ollama. - React UI: NER-centric PII editor, detector-models table, pattern/builtins editor, middleware default-policy UI. - Gallery: privacy-filter-multilingual token-classify model + NER install filter; token_classify known_usecase; batch sized to context for NER models. privacy-filter backend registered in the backend gallery (cpu/vulkan/cuda-13 meta + image entries with a capabilities map) matching its CI matrix jobs, and an /import-model auto-detect importer (PrivacyFilterImporter, narrow privacy-filter GGUF detection) replacing the prior pref-only registration. Reconciled against master's independent evolution: - Dropped master's PIIPatternOverrides feature (global-pattern runtime overrides + /api/pii/patterns API + runtime_settings.json persistence). The per-model NER + pattern-detector design supersedes it; it was built on the global redactor pattern set this branch replaced. - Reverted the llama.cpp Score carry-patch (0006-server-task-type-score): removed the patch and restored master's grpc-server.cpp Score RPC (direct llama_decode, slot-loop bypass) and LLAMA_VERSION pin, plus master's model_config validation forbidding score + chat/completion/embeddings on llama-cpp. token_classify is unaffected (it runs on the privacy-filter backend, not llama-cpp).

Tighten to 0o750 (no world access needed for backend-written export output). - G304: writeDepthPNG creates req.GetDst(). That path is chosen by the LocalAI core as the intended output destination (same pattern every image backend uses), not attacker input, so annotate with #nosec G304 and document why. The remaining G103 "audit unsafe" notes on the unsafe.Slice C-buffer copies are warning-level (the same purego interop whisper/parakeet use) and do not gate the check, per the supertonic exclusion precedent in secscan.yaml.

fix(mlx): route vision-language models to the mlx-vlm backend (#10274)
Vision-language checkpoints such as mlx-community/gemma-4-E4B-it-qat-4bit declare the "image-text-to-text" pipeline tag on HuggingFace. The mlx importer hardcoded backend "mlx" for every mlx-community model, so these VLMs were served by the text-only mlx-lm backend whose tokenizer does not carry the processor chat template. The template was never applied and the model produced degenerate, looping output that echoed the prompt. Detect the "image-text-to-text" pipeline tag in the importer and route those models to mlx-vlm, which applies the processor-aware chat template. An explicit backend preference still wins. As a defensive backstop, the mlx backend now warns loudly when the loaded model has no chat template, so a misrouted VLM surfaces the problem instead of silently looping.

fix(router): production-ready request router + auto-size batch for embedding/rerank (#10104)
* fix(router): score classifier production-readiness Conversation trimming runs through the classifier model's chat template and trims by exact token count, sized to the model's n_batch which is now scaled to context so long probes can't crash the backend. Missing chat_message templates are a hard error at router build time. Router- facing factories (Embedder/Scorer/Reranker/TokenCounter) re-resolve ModelConfig per call so a model installed post-startup doesn't bind a stub Backend="" config and silently fall into the loader's auto- iterate path. New 'vector_store' backend trace recorded inside localVectorStore on every Search/Insert — including the backend-load-failure path that previously vanished into an xlog.Warn — with outcome tagging (hit/miss/empty_store/backend_load_error/find_error/insert_error/ok). Companion cleanup drops misleading similarity:0 and input_tokens_count:0 from non-hit and text-mode traces. Gallery local-store-development aliases to 'local-store' so the master image satisfies pkg/model.LocalStoreBackend lookups from the embedding cache. Misc: llama-cpp TokenizeString reads the correct 'prompt' JSON key (the original bug); ModelTokenize nil-guard; non-fatal mitm proxy startup; PII 'route_local' renamed to 'allow' with docs/UI in sync; model-editor footer no longer eats the edit area on small screens; several config-editor template/dropdown/section fixes. Tests: e2e router specs (casual/code-hint + long-conversation trim), vector_store trace specs, lazy-factory specs, gallery dev-alias resolution, Playwright trace badge + scroll regression. Assisted-by: Claude:claude-opus-4-7 [Claude Code] Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(backend): auto-size batch to context for embedding and rerank models Embedding and rerank models pool over the whole input in a single physical batch (n_ubatch). With batch left at the 512 default, the backend rejects longer inputs with "input is too large to process", silently capping a large-context embedder (e.g. 8k/32k) at 512 tokens. Size n_batch to the context for these single-pass usecases, mirroring the existing FLAG_SCORE behaviour; an explicit batch: still wins. Extracts EffectiveContextSize/EffectiveBatchSize from grpcModelOpts so the effective decode window has one home for other callers to reuse. Adds an e2e-aio regression test that embeds a >512-token input. The AIO embedding model is switched to nomic-embed-text-v1.5 (2048 context) because the previous granite model was capped at 512 tokens and could not exercise the larger batch. Assisted-by: claude-code:claude-opus-4-8 [Claude Code] Signed-off-by: Richard Palethorpe <io@richiejp.com> * fix(gallery): raise arch-router scoring output cap via parallel:64 Scoring decodes the whole prompt+candidate in a single llama_decode and reads one logit row per candidate token. The vendored llama.cpp server caps causal output rows at n_parallel, so the default of 1 aborts with GGML_ASSERT(n_outputs_max <= cparams.n_outputs_max) on multi-token route labels. Set options: [parallel:64] on both arch-router quant entries to lift the cap; kv_unified (the grpc-server default) keeps the full context per sequence, so this does not split the KV cache.

feat(parakeet-cpp): add NVIDIA NeMo Parakeet ASR backend (parakeet.cpp) (#10084)
* feat(parakeet-cpp): L0 backend scaffold, LoadModel + AudioTranscription (text) Add a Go gRPC backend that bridges LocalAI to parakeet.cpp via the flat C-API (parakeet_capi.h), loaded with purego (cgo-less, mirrors the whisper / vibevoice-cpp backends). L0 scope: - main.go: dlopen libparakeet.so (override via PARAKEET_LIBRARY), register the C-API entry points, start the gRPC server. - goparakeetcpp.go: Load (parakeet_capi_load), AudioTranscription (parakeet_capi_transcribe_path, decoder=0 = per-arch default head), Free, serialized through base.SingleThread since the C engine is a thread-unsafe singleton. char* returns are bound as uintptr so the malloc'd buffer is freed via parakeet_capi_free_string after copy. - AudioTranscriptionStream returns a clear "not implemented in L0" error (closes the channel so the server doesn't hang), wired in L2. - Makefile: clone-at-pin + cmake (PARAKEET_VERSION for bump_deps.sh), with a local-symlink dev shortcut; run.sh / package.sh mirror whisper. - Test auto-skips without PARAKEET_BACKEND_TEST_MODEL/_WAV fixtures. Builds clean (CGO_ENABLED=0), gofmt clean, test passes. The single unsafeptr vet note in goStringFromCPtr is documented and matches the whisper backend's tolerated pattern. Word/segment timestamps (L1) and cache-aware streaming (L2) follow. Assisted-by: Claude:claude-opus-4-8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(parakeet-cpp): L1 word/segment timestamps via transcribe_path_json AudioTranscription now calls parakeet_capi_transcribe_path_json and shapes the per-word / per-token timestamps into the TranscriptResult: - Bind parakeet_capi_transcribe_path_json (purego, char* as uintptr like the other returns) and register it in main.go + the test loader. - Parse the JSON document ({"text","words":[{w,start,end,conf}], "tokens":[{id,t,conf}]}) into typed structs. - Synthesise a single whole-clip segment (parakeet emits no native segment boundaries) spanning the first word start to the last word end; token ids populate Segment.Tokens. - Attach word-level timings only when timestamp_granularities=["word"], matching the OpenAI API (segment-level default). secondsToNanos mirrors the whisper backend's nanosecond convention. Verified end-to-end against tdt_ctc-110m (f16): both the default and word-granularity specs pass; builds clean, gofmt clean, vet shows only the one documented unsafeptr note shared with the whisper backend. Cache-aware streaming (L2) follows.

Honours context cancellation between chunks. Frees every malloc'd delta and the session. Verified end-to-end against realtime_eou_120m-v1 (f16): the streamed transcript matches the offline 110m reference word-for-word, deltas reconstruct the final text, and the spec passes alongside the offline specs.

It deliberately does NOT claim arbitrary llama-style GGUFs, nor the upstream nvidia/parakeet-* NeMo repos (.nemo, not runnable here). - Registered in the ASR batch BEFORE LlamaCPPImporter so its GGUFs aren't swallowed by the generic .gguf importer. - Import nests files under parakeet-cpp/models/<name>/, defaults to the smallest quant (q4_k, near-lossless on parakeet) with a size-ladder fallback, and honours preferences.quantizations / name / description. Tested with synthetic HF details (no network): metadata, positive matches (HF repo, direct URL, preference), narrowness negatives (llama GGUF, NeMo repo), and import (default quant, override, direct URL), 9 specs pass, build/vet/gofmt clean.

Build ggml static + PIC (BUILD_SHARED_LIBS=OFF, CMAKE_POSITION_INDEPENDENT_CODE=ON) so libparakeet.so embeds ggml and depends only on system libs already present in the runtime image.

Per LocalAI's streaming contract (and the whisper backend), a non-streaming model should fall back to a single offline transcription emitted as one delta plus a closing FinalResult. Do that instead of erroring, so the streaming endpoint works for every parakeet model. Verified locally: the streaming spec passes against the non-streaming 110m model via fallback.

feat(backend): rfdetr-cpp native object detection + segmentation backend (#10028)
Adds a Go native gRPC backend that dlopens librfdetrcpp.so (built from
mudler/rf-detr.cpp at the pinned RFDETR_VERSION) via purego and exposes
the rfdetr.cpp inference pipeline through LocalAI's existing Detect RPC.
Supports all 5 RF-DETR detection variants (Nano/Small/Base/Medium/Large)
and 6 segmentation variants (SegNano/SegSmall/SegMedium/SegLarge/
SegXLarge/Seg2XLarge) with F32/F16/Q8_0/Q4_K quantizations. Pre-built
GGUFs ship at mudler/rfdetr-cpp-* on HuggingFace.
Detection returns Bbox + class_name + confidence; segmentation also
returns PNG-encoded per-detection masks via the rfdetr_capi accessor
functions (rfdetr_capi_get_detection_{class_id,box,score,class_name,
mask_png}).
End-to-end verified through POST /v1/detection: HTTP -> gRPC -> purego
dlopen -> rfdetr.cpp -> ggml -> response (9 detections on the detection
model, 21 detections + valid PNG masks on the seg-nano model against
the kitchen fixture).
Wiring:
- backend/go/rfdetr-cpp/{main.go,gorfdetrcpp.go,CMakeLists.txt,
Makefile,run.sh,package.sh,test.sh,.gitignore}
- Top-level Makefile: BACKEND_RFDETR_CPP, docker-build target,
.NOTPARALLEL, prepare-test-extra, test-extra
- backend/go/rfdetr-cpp/Makefile: `test` target invoked by test-extra
- .github/backend-matrix.yml: CPU + CUDA-12/13 + L4T CUDA-12/13
(arm64) + HIP + Vulkan (amd64 + arm64) + SYCL f32/f16
- backend/index.yaml: rfdetr-cpp meta anchor + latest/development
image entries for every matrix tag-suffix

feat(gallery): verify backend OCI images with keyless cosign (#9823)
* feat(gallery): verify backend OCI images with keyless cosign Close a trust gap where a registry compromise or MITM could silently replace a backend image: the gallery YAML tells LocalAI which image to pull, but until now nothing verified the bytes came from our CI. Consumer (pkg/oci/cosignverify): - New package using sigstore-go to verify keyless-cosign signatures. - OCI 1.1 referrers API + new bundle format (no legacy :tag.sig). - Policy fields: Issuer / IssuerRegex / Identity / IdentityRegex / NotBefore. NotBefore is the revocation lever — keyless Fulcio certs are ephemeral so revocation is policy-side; advancing not_before in the gallery YAML invalidates every signature predating the cutoff. - TUF trusted root cached process-wide so N backends from one gallery do 1 fetch, not N. Plumbing: - pkg/downloader: ImageVerifier interface + WithImageVerifier option threaded through DownloadFileWithContext. Verification runs between oci.GetImage and oci.ExtractOCIImage, with digest pinning via pinnedImageRef to close the TOCTOU window. Skips the verifier's HEAD when the ref is already digest-pinned. - core/config: Gallery.Verification YAML block. - core/gallery: backendDownloadOptions builds the verifier from the policy; applied on initial URI, mirrors, and tag fallbacks. - core/gallery/upgrade: the upgrade path now routes through the same options builder. A regression Ginkgo spec pins this contract — without it, UpgradeBackend silently bypassed verification. - core/cli: --require-backend-integrity (LOCALAI_REQUIRE_BACKEND_INTEGRITY) escalates missing policy / empty SHA256 from warn to hard-fail. Producer (.github/workflows/backend_merge.yml): - id-token: write at job scope (PR-fork-safe via existing event gate). - sigstore/cosign-installer@v3 pinned to v2.4.1. - After each docker buildx imagetools create, resolve the manifest list digest and run cosign sign --recursive --new-bundle-format --registry-referrers-mode=oci-1-1 against repo@digest. --recursive signs the index and every per-arch entry, matching how the consumer resolves a tag to a platform-specific manifest before verifying. Rollout: backend/index.yaml has no `verification:` block yet, so this PR is backward-compatible — installs proceed with a warning until the gallery is populated. Strict mode is opt-in.

This leaked process state into the gallery package and made the flag impossible to override per-call or test without touching the env. Add RequireBackendIntegrity to ApplicationConfig (with a matching WithRequireBackendIntegrity AppOption) and thread the bool through every install/upgrade path: InstallBackend, InstallBackendFromGallery, UpgradeBackend, InstallModelFromGallery, InstallExternalBackend, ApplyGalleryFromString/File, startup.InstallModels. Worker subcommands gain the same env-bound flag on WorkerFlags so distributed-worker installs honor it consistently with the worker daemon path. Add a forbidigo lint rule against os.Getenv / os.LookupEnv / os.Environ to keep the env-leak pattern from creeping back.

feat(llama-cpp): bump to MTP-merge SHA and automatically set MTP defaults (#9852)
* feat(llama-cpp): bump to MTP-merge SHA and document draft-mtp spec type Update LLAMA_VERSION to 0253fb21 (post ggml-org/llama.cpp#22673 merge, 2026-05-16) to pick up Multi-Token Prediction support. No grpc-server.cpp changes are required: the existing `spec_type` option delegates to upstream's `common_speculative_types_from_names()`, which already accepts the new `draft-mtp` name. The `n_rs_seq` cparam needed by MTP is auto-derived inside `common_context_params_to_llama` from `params.speculative.need_n_rs_seq()`, and when no `draft_model` is set the upstream server builds the MTP context off the target model itself. Docs: extend the speculative-decoding section of the model-configuration guide with the new type, both load paths (MTP head embedded in the main GGUF vs. separate `mtp-*.gguf` sibling), the PR's recommended `spec_n_max:2-3`, and the chained `draft-mtp,ngram-mod` recipe. Also notes that the upstream `-hf` auto-discovery of `mtp-*.gguf` siblings is not wired through LocalAI's gRPC layer. Agent guide: short note explaining that new upstream spec types are picked up automatically and that MTP needs no gRPC plumbing. Assisted-by: Claude:claude-opus-4-7 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(llama-cpp): auto-detect MTP heads and enable draft-mtp on import + load Detect upstream's `<arch>.nextn_predict_layers` GGUF metadata key (set by `convert_hf_to_gguf.py` for Qwen3.5/3.6 family models and similar) and, when present and the user has not configured a `spec_type` explicitly, auto-append the upstream-recommended speculative-decoding tuple: - spec_type:draft-mtp - spec_n_max:6 - spec_p_min:0.75 The 0.75 p_min is pinned defensively because upstream marks the current default with a "change to 0.0f" TODO; locking it here keeps acceptance thresholds stable across future llama.cpp bumps. Detection runs in two places: - The model importer (`POST /models/import-uri`, the `/import-model` UI) range-fetches the GGUF header for HuggingFace / direct-URL imports via `gguf.ParseGGUFFileRemote`, with a 30s timeout and non-fatal error handling. OCI/Ollama URIs are skipped because the artifact is not directly streamable; the load-time hook covers them once the file is on disk. - The llama-cpp load-time hook (`guessGGUFFromFile`) reads the local header on every model start and appends the same options if `spec_type` is not already set. Both paths share `ApplyMTPDefaults` and respect an explicit user-set `spec_type:` / `speculative_type:` so YAML overrides win. Ginkgo specs cover the append, preserve-user-choice, legacy alias, and nil safety paths.

Live-test against `huggingface://ggml-org/Qwen3.6-27B-MTP-GGUF/Qwen3.6-27B-MTP-Q8_0.gguf` exposed this: the probe failed with `unsupported protocol scheme "huggingface"`, was caught by the non-fatal error path, and the MTP options were silently never applied to the generated YAML. Route every candidate URI through `downloader.URI.ResolveURL()` and require the resolved form to be HTTP(S). After the fix the probe successfully reads `<arch>.nextn_predict_layers=1` from the real HF GGUF and the emitted ConfigFile carries spec_type:draft-mtp, spec_n_max:6, spec_p_min:0.75 as intended.

feat(realtime): Add Liquid Audio s2s model and assistant mode on talk page (#9801)
* feat(liquid-audio): add LFM2.5-Audio any-to-any backend + realtime_audio usecase
Wires LiquidAI's LFM2.5-Audio-1.5B as a self-contained Realtime API model:
single engine handles VAD, transcription, LLM, and TTS in one bidirectional
stream — drop-in alternative to a VAD+STT+LLM+TTS pipeline.
Backend
- backend/python/liquid-audio/ — new Python gRPC backend wrapping the
`liquid-audio` package. Modes: chat / asr / tts / s2s, voice presets,
Load/Predict/PredictStream/AudioTranscription/TTS/VAD/AudioToAudioStream/
Free and StartFineTune/FineTuneProgress/StopFineTune. Runtime monkey-patch
on `liquid_audio.utils.snapshot_download` so absolute local paths from
LocalAI's gallery resolve without a HF round-trip. soundfile in place of
torchaudio.load/save (torchcodec drags NVIDIA NPP we don't bundle).
- backend/backend.proto + pkg/grpc/{backend,client,server,base,embed,
interface}.go — new AudioToAudioStream RPC mirroring AudioTransformStream
(config/frame/control oneof in; typed event+pcm+meta out).
- core/services/nodes/{health_mock,inflight}_test.go — add stubs for the
new RPC to the test fakes.
Config + capabilities
- core/config/backend_capabilities.go — UsecaseRealtimeAudio, MethodAudio
ToAudioStream, UsecaseInfoMap entry, liquid-audio BackendCapability row.
- core/config/model_config.go — FLAG_REALTIME_AUDIO bitmask, ModalityGroups
membership in both speech-input and audio-output groups so a lone flag
still reads as multimodal, GetAllModelConfigUsecases entry, GuessUsecases
branch.
Realtime endpoint
- core/http/endpoints/openai/realtime.go — extract prepareRealtimeConfig()
so the gate is unit-testable; accept realtime_audio models and self-fill
empty pipeline slots with the model's own name (user-pinned slots win).
- core/http/endpoints/openai/realtime_gate_test.go — six specs covering nil
cfg, empty pipeline, legacy pipeline, self-contained realtime_audio,
user-pinned VAD slot, and partial legacy pipeline.
UI + endpoints
- core/http/routes/ui.go — /api/pipeline-models accepts either a legacy
VAD+STT+LLM+TTS pipeline or a realtime_audio model; surfaces a
self_contained flag so the Talk page can collapse the four cards.
- core/http/routes/ui_api.go — realtime_audio in usecaseFilters.
- core/http/routes/ui_pipeline_models_test.go — covers both code paths.
- core/http/react-ui/src/pages/Talk.jsx — self-contained badge instead of
the four-slot grid; rename Edit Pipeline → Edit Model Config; less
pipeline-specific wording.
- core/http/react-ui/src/pages/Models.jsx + locales/en/models.json — new
realtime_audio filter button + i18n.
- core/http/react-ui/src/utils/capabilities.js — CAP_REALTIME_AUDIO.
- core/http/react-ui/src/pages/FineTune.jsx — voice + validation-dataset
fields, surfaced when backend === liquid-audio, plumbed via
extra_options on submit/export/import.
Gallery + importer
- gallery/liquid-audio.yaml — config template with known_usecases:
[realtime_audio, chat, tts, transcript, vad].
- gallery/index.yaml — four model entries (realtime/chat/asr/tts) keyed by
mode option. Fixed pre-existing `transcribe` typo on the asr entry
(loader silently dropped the unknown string → entry never surfaced as a
transcript model).
- gallery/lfm.yaml — function block for the LFM2 Pythonic tool-call format
`<|tool_call_start|>[name(k="v")]<|tool_call_end|>` matching
common_chat_params_init_lfm2 in vendored llama.cpp.
- core/gallery/importers/{liquid-audio,liquid-audio_test}.go — detector
matches LFM2-Audio HF repos (excludes -gguf mirrors); mode/voice
preferences plumbed through to options.
- core/gallery/importers/importers.go — register LiquidAudioImporter
before LlamaCPPImporter.
- pkg/functions/parse_lfm2_test.go — seven specs for the response/argument
regex pair on the LFM2 pythonic format.
Build matrix
- .github/backend-matrix.yml — seven liquid-audio targets (cuda12, cuda13,
l4t-cuda-13, hipblas, intel, cpu amd64, cpu arm64). Jetpack r36 cuda-12
is skipped (Ubuntu 22.04 / Python 3.10 incompatible with liquid-audio's
3.12 floor).
- backend/index.yaml — anchor + 13 image entries.
- Makefile — .NOTPARALLEL, prepare-test-extra, test-extra,
docker-build-liquid-audio.
Docs
- .agents/plans/liquid-audio-integration.md — phased plan; PR-D (real
any-to-any wiring via AudioToAudioStream), PR-E (mid-audio tool-call
detector), PR-G (GGUF entries once upstream llama.cpp PR #18641 lands)
remain.
- .agents/api-endpoints-and-auth.md — expand the capability-surface
checklist with every place a new FLAG_* needs to be registered.

* feat(realtime): function calling + history cap for any-to-any models
Three pieces, all on the realtime_audio path that just landed:
1. liquid-audio backend (backend/python/liquid-audio/backend.py):
- _build_chat_state grows a `tools_prelude` arg.
- new _render_tools_prelude parses request.Tools (the OpenAI Chat
Completions function array realtime.go already serialises) and
emits an LFM2 `<|tool_list_start|>…<|tool_list_end|>` system turn
ahead of the user history. Mirrors gallery/lfm.yaml's `function:`
template so the model sees the same prompt shape whether served
via llama-cpp or here. Without this the backend silently dropped
tools — function calling was wired end-to-end on the Go side but
the model never saw a tool list.
2. Realtime history cap (core/http/endpoints/openai/realtime.go):
- Session grows MaxHistoryItems int; default picked by new
defaultMaxHistoryItems(cfg) — 6 for realtime_audio models (LFM2.5
1.5B degrades quickly past a handful of turns), 0/unlimited for
legacy pipelines composing larger LLMs.
- triggerResponse runs conv.Items through trimRealtimeItems before
building conversationHistory. Helper walks the cut left if it
would orphan a function_call_output, so tool result + call pairs
stay intact.
- realtime_gate_test.go: specs for defaultMaxHistoryItems and
trimRealtimeItems (zero cap, under cap, over cap, tool-call pair
preservation).
3. Talk page (core/http/react-ui/src/pages/Talk.jsx):
- Reuses the chat page's MCP plumbing — useMCPClient hook,
ClientMCPDropdown component, same auto-connect/disconnect effect
pattern. No bespoke tool registry, no new REST endpoints; tools
come from whichever MCP servers the user toggles on, exactly as
on the chat page.
- sendSessionUpdate now passes session.tools=getToolsForLLM(); the
update re-fires when the active server set changes mid-session.
- New response.function_call_arguments.done handler executes via
the hook's executeTool (which round-trips through the MCP client
SDK), then replies with conversation.item.create
{type:function_call_output} + response.create so the model
completes its turn with the tool output. Mirrors chat's
client-side agentic loop, translated to the realtime wire shape.
UI changes require a LocalAI image rebuild (Dockerfile:308-313 bakes
react-ui/dist into the runtime image). Backend.py changes can be
swapped live in /backends/<id>/backend.py + /backend/shutdown.

* feat(realtime): LocalAI Assistant ("Manage Mode") for the Talk page
Mirrors the chat-page metadata.localai_assistant flow so users can ask the
realtime model what's loaded / installed / configured. Tools are run
server-side via the same in-process MCP holder that powers the chat
modality — no transport switch, no proxy, no new wire protocol.
Wire:
- core/http/endpoints/openai/realtime.go:
- RealtimeSessionOptions{LocalAIAssistant,IsAdmin}; isCurrentUserAdmin
helper mirrors chat.go's requireAssistantAccess (no-op when auth
disabled, else requires auth.RoleAdmin).
- Session grows AssistantExecutor mcpTools.ToolExecutor.
- runRealtimeSession, when opts.LocalAIAssistant is set: gate on admin,
fail closed if DisableLocalAIAssistant or the holder has no tools,
DiscoverTools and inject into session.Tools, prepend
holder.SystemPrompt() to instructions.
- Tool-call dispatch loop: when AssistantExecutor.IsTool(name), run
ExecuteTool inproc, append a FunctionCallOutput to conv.Items, skip
the function_call_arguments client emit (the client can't execute
these — it doesn't know about them). After the loop, if any
assistant tool ran, trigger another response so the model speaks the
result. Mirrors chat's agentic loop, driven server-side rather than
via client round-trip.
- core/http/endpoints/openai/realtime_webrtc.go: RealtimeCallRequest
gains `localai_assistant` (JSON omitempty). Handshake calls
isCurrentUserAdmin and builds RealtimeSessionOptions.
- core/http/react-ui/src/pages/Talk.jsx: admin-only "Manage Mode"
checkbox under the Tools dropdown; passes localai_assistant: true to
realtimeApi.call's body, captured in the connect callback's deps.
Mirroring chat's pattern means the in-process MCP tools surface "just
works" for the Talk page without exposing a Streamable-HTTP MCP endpoint
(which was the alternative). Clients with their own MCP servers can
still use the existing ClientMCPDropdown path in parallel; the realtime
handler distinguishes them by AssistantExecutor.IsTool() at dispatch
time.

* feat(realtime): render Manage Mode tool calls in the Talk transcript
Previously the realtime endpoint only emitted response.output_item.added
for the FunctionCall item, and Talk.jsx's switch ignored the event — so
server-side tool runs were invisible in the UI. The model would speak
the result but the user had no way to see what tool was actually
called.
realtime.go: after executing an assistant tool inproc, emit a second
output_item.added/.done pair for the FunctionCallOutput item. Mirrors
the way the chat page displays tool_call + tool_result blocks.
Talk.jsx: handle both response.output_item.added and .done. Render
FunctionCall (with arguments) and FunctionCallOutput (pretty-printed
JSON when possible) as two transcript entries — `tool_call` with the
wrench icon, `tool_result` with the clipboard icon, both in mono-space
secondary-colour. Resets streamingRef after the result so the next
assistant text delta starts a fresh transcript entry instead of
appending to the previous turn.

* refactor(realtime): bound the Manage Mode tool-loop + preserve assistant tools
Fallout from a review pass on the Manage Mode patches:
- Bound the server-side agentic loop. triggerResponse used to recurse on
executedAssistantTool with no cap — a model that kept calling tools
would blow the goroutine stack. New maxAssistantToolTurns = 10 (mirrors
useChat.js's maxToolTurns). Public triggerResponse is now a thin shim
over triggerResponseAtTurn(toolTurn int); recursion increments the
counter and stops at the cap with an xlog.Warn.
- Preserve Manage Mode tools across client session.update. The handler
used to blindly overwrite session.Tools, so toggling a client MCP
server mid-session silently wiped the in-process admin tools. Session
now caches the original AssistantTools slice at session creation and
the session.update handler merges them back in (client names win on
collision — the client is explicit).
- strconv.ParseBool for the localai_assistant query param instead of
hand-rolled "1" || "true". Mirrors LocalAIAssistantFromMetadata.
- Talk.jsx: render both tool_call and tool_result on
response.output_item.done instead of splitting them across .added and
.done. The server's event pairing (added → done) stays correct; the
UI just doesn't need to inspect both phases of the same item. One
switch case instead of two, no behavioural change.
Out of scope (noted for follow-ups): extract a shared assistant-tools
helper between chat.go and realtime.go (duplication is small enough
that two parallel implementations stay readable for now), and an i18n
key for the Manage Mode helper text (Talk.jsx doesn't use i18n
anywhere else yet).

* ci(test-extra): wire liquid-audio backend smoke test
The backend ships test.py + a `make test` target and is listed in
backend-matrix.yml, so scripts/changed-backends.js already writes a
`liquid-audio=true|false` output when files under backend/python/liquid-audio/
change. The workflow just wasn't reading it.
- Expose the `liquid-audio` output on the detect-changes job
- Add a tests-liquid-audio job that runs `make` + `make test` in
backend/python/liquid-audio, gated on the per-backend detect flag
The smoke covers Health() and LoadModel(mode:finetune); fine-tune mode
short-circuits before any HuggingFace download (backend.py:192), so the
job needs neither weights nor a GPU. The full-inference path remains
gated on LIQUID_AUDIO_MODEL_ID, which CI doesn't set.
The four new Go test files (core/gallery/importers/liquid-audio_test.go,
core/http/endpoints/openai/realtime_gate_test.go,
core/http/routes/ui_pipeline_models_test.go, pkg/functions/parse_lfm2_test.go)
are already picked up by the existing test.yml workflow via `make test` →
`ginkgo -r ./pkg/... ./core/...`; their packages all carry RunSpecs entries.

fix(gallery): keep auto-upgrade off non-dev backends when -development is installed (#9736)
A `-development` backend variant (e.g. `cuda12-llama-cpp-development`)
shares its `alias` with the stable counterpart and is meant to be a
drop-in replacement via ListSystemBackends alias resolution. Two paths
in the auto-upgrade flow let the stable variant slip back in on top of
the user's explicit dev pick:
1. ListSystemBackends emits a synthetic alias row keyed by the alias
name that re-uses the chosen concrete's metadata pointer. In
distributed mode, the worker's handleBackendList serialised that
row over NATS as `{Name: <alias>, URI: <dev URI>, Digest: <dev>}`
— the frontend can't reconstruct the alias relationship, and the
wire-rebuilt row then carried `Metadata.Name = <alias>` and
resolved against an unrelated gallery entry on the next upgrade
check.
2. CheckUpgradesAgainst happily iterated the synthetic row in
single-node too. Today the duplicate gallery lookup is harmless
because both rows share the same `Metadata.Name`, but any gallery
change that gives a meta backend a version, or any concrete
sharing its alias with a dev counterpart, would surface a phantom
non-dev upgrade and auto-upgrade would install it — shadowing the
dev one through alias-token preference.
Two layered fixes:
- `core/services/worker/lifecycle.go` (`handleBackendList`): drop
rows where the map key differs from `b.Metadata.Name`. Concrete
and meta entries always have `key == Metadata.Name`; only synthetic
aliases violate it. Workers now report only what's actually on disk;
the per-node UI listing and CheckUpgrades both stop seeing phantoms.
- `core/gallery/upgrade.go` (`CheckUpgradesAgainst`): iterate by key,
skip rows where `key != Metadata.Name` (belt-and-suspenders for any
caller-supplied installed set), and apply the dev-aware rule —
build a set of installed `Metadata.Name`s and drop any non-dev
candidate `X` whose `X-<devSuffix>` counterpart is installed. Uses
the configured dev suffix from `getFallbackTagValues(systemState)`.
Manual `POST /api/backends/upgrade/<name>` is unaffected: it goes
straight through `bm.UpgradeBackend(name)` without consulting the
suppression list, so users who genuinely want the stable variant
upgraded can still trigger it explicitly.
Tests in core/gallery/upgrade_test.go cover three cases under
"CheckUpgradesAgainst (distributed)": dev-only installed → only the
dev surfaces; both variants installed → dev still wins; synthetic
alias row is ignored. Generic backend names are used to avoid the
capability filter dropping cuda-prefixed entries on a CPU-only host.

chore: Security hardening (#9719)
* fix(http): close 0.0.0.0/[::] SSRF bypass in /api/cors-proxy The CORS proxy carried its own private-network blocklist (RFC 1918 + a handful of IPv6 ranges) instead of using the same classification as pkg/utils/urlfetch.go. The hand-rolled list missed 0.0.0.0/8 and ::/128, both of which Linux routes to localhost — so any user with FeatureMCP (default-on for new users) could reach LocalAI's own listener and any other service bound to 0.0.0.0:port via: GET /api/cors-proxy?url=http://0.0.0.0:8080/... GET /api/cors-proxy?url=http://[::]:8080/... Replace the custom check with utils.IsPublicIP (Go stdlib IsLoopback / IsLinkLocalUnicast / IsPrivate / IsUnspecified, plus IPv4-mapped IPv6 unmasking) and add an upfront hostname rejection for localhost, *.local, and the cloud metadata aliases so split-horizon DNS can't paper over the IP check. The IP-pinning DialContext is unchanged: the validated IP from the single resolution is reused for the connection, so DNS rebinding still cannot swap a public answer for a private one between validate and dial. Regression tests cover 0.0.0.0, 0.0.0.0:PORT, [::], ::ffff:127.0.0.1, ::ffff:10.0.0.1, file://, gopher://, ftp://, localhost, 127.0.0.1, 10.0.0.1, 169.254.169.254, metadata.google.internal.

Subsequent code that operated on filePath (a backend launcher, a YAML loader, a re-download that finds the file already present and skips) would consume the attacker-supplied bytes. Reorder: verify the streamed hash first, remove the .partial on mismatch, then rename. The streamed hash is computed during io.Copy so no second read is needed. While here, raise the empty-SHA case from a Debug log to a Warn so "this download had no integrity check" is visible at the default log level. Backend installs currently pass through with no digest; the warning makes that footprint observable without changing behaviour.

With LOCALAI_ADMIN_EMAIL set, an attacker who could register on the configured OIDC IdP under that email (some IdPs accept self-supplied unverified emails) inherited admin role: - first login: AssignRole(tx, email, adminEmail) → RoleAdmin - re-login: MaybePromote(db, user, adminEmail) → flip to RoleAdmin Add EmailVerified to oauthUserInfo, parse email_verified from the OIDC claims (default false on absence so an IdP that omits the claim cannot short-circuit the gate), and substitute "" for the role-decision email when verified=false via emailForRoleDecision. The user record still stores the unverified email for display. GitHub's path defaults EmailVerified=true: GitHub only returns a public profile email after verification, and fetchGitHubPrimaryEmail explicitly filters to Verified=true. Regression tests cover both the helper contract and integration with AssignRole, including the bootstrap "first user" branch that would otherwise mask the gate.

That is fine for a developer laptop, a home LAN, or a Tailnet — the network itself is the trust boundary. It is not fine on a public IP, where every model install, settings change, and admin endpoint becomes reachable from the internet. Refuse to start in that exact configuration. Loopback, RFC 1918, RFC 4193 ULA, link-local, and RFC 6598 CGNAT (Tailscale's default range) all count as trusted; wildcard binds (`:port`, `0.0.0.0`, `[::]`) are accepted only when every host interface is in one of those ranges. Hostnames are resolved and treated as trusted only when every answer is. A new --allow-insecure-public-bind / LOCALAI_ALLOW_INSECURE_PUBLIC_BIND flag opts out for deployments that gate access externally (a reverse proxy enforcing auth, a mesh ACL, etc.). The error message lists this plus the three constructive alternatives (bind a private interface, enable --auth, set --api-keys). The interface enumeration goes through a package-level interfaceAddrsFn var so tests can simulate cloud-VM, home-LAN, Tailscale-only, and enumeration-failure topologies without poking at the real network stack.

The chat route is FeatureChat-gated (default-on), and the assistant's in-process MCP server can install/delete models and edit configs — the wrong handler change would silently turn the LLM into a confused deputy. Extract the gate into requireAssistantAccess(c, authEnabled) and pin its behaviour: auth disabled is a no-op, unauthenticated is 403, RoleUser is 403, RoleAdmin and the synthetic legacy-key admin are admitted. No behaviour change in the production path. Assisted-by: Claude:claude-opus-4-7 [Claude Code] Signed-off-by: Richard Palethorpe <io@richiejp.com> * test(http): assert every API route is auth-classified The auth middleware classifies path prefixes (/api/, /v1/, /models/, etc.) as protected and treats anything else as a static-asset passthrough. A new endpoint shipped under a brand-new prefix — or a new path that simply isn't on the prefix allowlist — would be reachable anonymously. Walk every route registered by API() with auth enabled and a fresh in-memory database (no users, no keys), and assert each API-prefixed route returns 401 / 404 / 405 to an anonymous request. Public surfaces (/api/auth/*, /api/branding, /api/node/* token-authenticated routes, /healthz, branding asset server, generated-content server, static assets) are explicit allowlist entries with comments justifying them. Build-tagged 'auth' so it runs against the SQLite-backed auth DB (matches the existing auth suite).

A regression there is the difference between "regular user reads their own data" and "regular user reads anyone's data via ?user_id=victim". Lock in the contract: - effectiveUserID ignores ?user_id= for unauthenticated and RoleUser - effectiveUserID honours it for RoleAdmin and ProviderAgentWorker - wantsAllUsers requires admin AND the literal "true" string - canImpersonateUser is admin OR agent-worker, never plain RoleUser No production change — this commit only adds tests.

Assisted-by: Claude:claude-opus-4-7 [Claude Code] Signed-off-by: Richard Palethorpe <io@richiejp.com> * fix(http): redact secrets from trace buffer and distribution-token logs The /api/traces buffer captured Authorization, Cookie, Set-Cookie, and API-key headers verbatim from every request when tracing was enabled. The endpoint is admin-only but the buffer is reachable via any heap-style introspection and the captured tokens otherwise outlive the request. Strip those header values at capture time. Body redaction is left to a follow-up — the prompts are usually the operator's own and JSON-walking is invasive. Distribution tokens were also logged in plaintext from core/explorer/discovery.go; logs forward to syslog/journald and outlive the token. Redact those to a short prefix/suffix instead.

Add a separate 60/min/IP limiter for /api/auth/{github,oidc}/callback so callbacks are bounded against floods without breaking shared-IP deployments.

Galleries without sha256 keep working; the empty-SHA path still emits the existing "downloading without integrity check" warning.

Pin that contract: cross-site multipart POSTs are rejected; same-origin / same-site / API-key clients are not. Also pins the SameSite=Lax fallback path the skipper relies on when Sec-Fetch-Site is absent.

The CSP keeps script-src permissive because the Vite bundle relies on inline + eval'd scripts; tightening that requires moving to a nonce-based policy. - The <base href> injection in the SPA shell escaped attacker-controllable Host / X-Forwarded-Host headers — a single quote in the host header broke out of the attribute. Pass through SecureBaseHref (html.EscapeString). - Three React sinks rendering untrusted content via dangerouslySetInnerHTML switch to text-node rendering with whiteSpace: pre-wrap: user message bodies in Chat.jsx and AgentChat.jsx, and the agent activity log in AgentChat.jsx. The hand-rolled escape on the agent user-message variant is replaced by the same plain-text path. - New safeHref util collapses non-allowlisted URI schemes (most importantly javascript:) to '#'. Applied to gallery `<a href={url}>` links in Models / Backends / Manage and to canvas artifact links — these come from gallery JSON or assistant tool calls and must be treated as untrusted. - The branding asset server attaches a sandbox CSP plus same-origin CORP to .svg responses. The React UI loads logos via <img>, but the same URL is also reachable via direct navigation; this prevents script execution if a hostile SVG slipped past upload validation.

Set ReadHeaderTimeout (30s) to plug the slow-headers attack and IdleTimeout (120s) to cap keep-alive sockets. ReadTimeout and WriteTimeout stay at 0 because request bodies can be multi-GB model uploads and SSE / chat completions stream for many minutes; operators who need tighter per-request bounds should terminate slow clients at a reverse proxy.

Lock that down with a regression test so a future "let's just c.Bind(&user)" refactor breaks loudly.

The fine-tune upload was incidentally safe because of a UUID prefix that fused any leading '..' to a literal segment, but the protection is fragile. UploadToCollectionForUser handed the filename to a vendored backend without sanitising at all. Strip to filepath.Base at both boundaries and reject the trivial unsafe values ("", ".", "..", "/").

Validate every entry: types must match, URL must parse with http(s) scheme, header keys/values must be control-char-free. Drop anything that doesn't fit. Assisted-by: Claude:claude-opus-4-7 [Claude Code] Signed-off-by: Richard Palethorpe <io@richiejp.com> * fix(http): close X-Forwarded-Prefix open redirect The reverse-proxy support concatenated X-Forwarded-Prefix into the redirect target without validation, so a forged header value of "//evil.com" turned the SPA-shell redirect helper at /, /browse, and /browse/* into a 301 to //evil.com/app. The path-strip middleware had the same shape on its prefix-trailing-slash redirect. Add SafeForwardedPrefix at the middleware boundary: must start with a single '/', no protocol-relative '//' opener, no scheme, no backslash, no control characters. Apply at both consumers; misconfig trips the validator and the header is dropped.

An operator who flipped the strict-CORS feature flag without populating the list got the opposite of what they asked for. Echo never sets Allow-Credentials: true so this isn't directly exploitable (cookies aren't sent under wildcard CORS), but the misconfiguration trap is worth closing. Skip the registration and warn. Assisted-by: Claude:claude-opus-4-7 [Claude Code] Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(auth): zxcvbn password strength check with user-acknowledged override The previous policy was len < 8, which let through "Password1" and the rest of the credential-stuffing corpus. LocalAI has no second factor yet, so the bar needs to sit higher. Add ValidatePasswordStrength using github.com/timbutler/zxcvbn (an actively-maintained fork of the trustelem port; v1.0.4, April 2024): - min 12 chars, max 72 (bcrypt's truncation point) - reject NUL bytes (some bcrypt callers truncate at the first NUL) - require zxcvbn score >= 3 ("safely unguessable, ~10^8 guesses to break"); the hint list ["localai", "local-ai", "admin"] penalises passwords built from the app's own branding zxcvbn produces false positives sometimes (a strong-looking password that happens to match a dictionary word) and operators occasionally need to set a known-weak password (kiosk demos, CI rigs). Add an acknowledgement path: PasswordPolicy{AllowWeak: true} skips the entropy check while still enforcing the hard rules. The structured PasswordErrorResponse marks weak-password rejections as Overridable so the UI can surface a "use this anyway" checkbox. Wired through register, self-service password change, and admin password reset on both the server and the React UI.

The browser focused the field, showed a brief native tooltip, and that was that — no toast, no fetch, no clue. Reproducible by typing fewer than 12 chars on the second password change of a session. The JS-level length check in handleSubmit already shows a toast and the server rejects with a structured error, so the HTML5 attribute was redundant defence anyway. Drop it.

Loosening the CSP would defeat its purpose; the right fix is to stop reaching out to a third-party CDN for fonts on every page load. Add @fontsource-variable/geist and @fontsource-variable/geist-mono as npm deps and import them once at boot. Drop the <link rel="preconnect"> and external stylesheet from index.html. Side benefit: no third-party tracking via Referer / IP on every UI load, no failure mode when offline / behind a captive portal.

Update tooShort and newPasswordPlaceholder / newPasswordDescription across all five locales (en, es, it, de, zh-CN) to match the real ValidatePasswordStrength rule. Assisted-by: Claude:claude-opus-4-7 [Claude Code] Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(auth): make password length-floor overridable like the entropy check The 12-char minimum was a policy choice, not a technical invariant — only "non-empty", "<= 72 bytes", and "no NUL bytes" are real bcrypt constraints. Treating length-12 as a hard rule was inconsistent with the entropy check (already overridable) and friction for use cases where the account is just a name on a session, not a security boundary (single-user kiosk, CI rig, lab demo). Restructure ValidatePasswordStrength: - Hard rules (always enforced): non-empty, <= MaxPasswordLength, no NUL byte - Policy rules (skipped when AllowWeak=true): length >= 12, zxcvbn score >= 3 PasswordError now marks password_too_short as Overridable too. The React forms generalised from `error_code === 'password_too_weak'` to `overridable === true`, and the JS-side preflight length checks were removed (server is source of truth, returns the same checkbox flow).
