Adira	ef724a3c9d	feat(api): add /v1/detokenize endpoint (#9620) ... * feat(api): add /v1/detokenize endpoint Closes #1649. Mirror of the existing /v1/tokenize path, requested by @benniekiss in the issue thread for "complete API workflow" use cases that need to turn token IDs back into text without local processing. - Add Detokenize gRPC RPC with DetokenizeRequest{tokens} / DetokenizeResponse{content} messages. - Implement in the llama.cpp backend using common_token_to_piece, the same primitive TokenizeString already uses internally. - Other backends inherit the default Unimplemented from base.Base, in line with how Detect, Rerank, etc. are gated per-backend. - Wire up the Go gRPC interface, server, client, and in-process embed wrapper alongside their TokenizeString counterparts. - Add the schema types, ModelDetokenize wrapper, HTTP handler, route registration, RouteFeatureRegistry entry (gated by FeatureTokenize so no new feature flag is needed), and the discovery map entry under ai_functions. - Regenerated swagger reflects the new endpoint and types. - Update authentication.md to list /v1/detokenize alongside /v1/tokenize.

Addresses reviewer feedback on #9620. Assisted-by: Claude:claude-sonnet-4-6 Signed-off-by: Adira Denis Muhando <dennisadira@gmail.com> * fix(kokoros): implement detokenize in the Rust backend service The Detokenize RPC added in this PR grows the tonic-generated Backend trait. Unlike the other languages there is nothing to inherit a default from — Rust trait impls must list every method — so backend/rust/kokoros failed to compile: error[E0046]: not all trait items implemented, missing: `detokenize` --> src/service.rs:72:1 72 | impl Backend for KokorosService { Go backends pick up the Unimplemented default from base.Base, and the generated C++/Python servicer bases default to UNIMPLEMENTED, which is why the Rust backend was the only one that broke. kokoros is the sole Rust crate in the tree, so this is the full extent of the fallout. Return Status::unimplemented("Not supported"), matching how this same file already gates tokenize_string and ~20 other unsupported RPCs. Fixes the tests-kokoros and backend-jobs-singlearch-4 (-cpu-kokoros) failures on the previous head.

mudler's LocalAI [bot]	9c85cacfe3	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): 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): 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. Assisted-by: Claude:claude-opus-5 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * backend(audio-cpp): make the lane and identity guards structural Two hardenings ahead of the eleven handlers still to be written, both of which get harder to retrofit later. The lane proof-of-holding parameter was a const reference, which binds to a temporary, so session_for(rpc, shape, model->acquire(0)) compiled. Each such temporary dies at the end of its own full-expression, releasing the lane between two calls that must share one: precisely the split the parameter exists to prevent, and the form a future author is most likely to reach for because it reads as tidy. A non-const reference requires an lvalue, so the temporary form now fails to compile while the named-local handlers build unchanged. The header comment no longer implies the check is total either: it proves a lane was taken, not that it is this model's lane. The identity check was two lines each handler had to remember, with nothing failing if a new one forgot them and no C++ equivalent of model_identity_modalities_test.go to notice. snapshot() becomes snapshot_unchecked(), whose only legitimate caller is Status, since HealthMessage carries no ModelIdentity. Handlers go through snapshot_for(), which takes the counted reference, refuses when nothing is loaded, and runs the identity check before anything can route. Every handler already has to call something to obtain the model, so the guarded call is now the shortest path and skipping it means deliberately typing snapshot_unchecked. A convention that has to be remembered can rot; this cannot. Verified: the temporary-argument and inverted-order forms each fail to compile with the expected diagnostic, the real handlers build, and bypassing the guard in Diarize alone turns the identity test red on that RPC while VAD stays green.

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

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

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

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

As a warning that is not enough: adding a sixth enumerator and building the shipping target gives exit 0, a binary and one warning, and the trailing `return surfaces[0];` then answers the new RPC with AudioEncode's codec reason. That is a confident, specific and false statement about audio.cpp on the wire, on the one code path whose entire job is to be truthful about what this backend cannot do, and it is worse than the runtime fallback it replaced, which at least named itself as a bug in this file. capability_routing.cpp therefore joins loaded_model.cpp on the existing -Werror=switch pin, whose comment already made this argument for the engine enum. The comment now covers both files. The pin stays per-file rather than project-wide because upstream's own ace_step/vae_decoder.cpp has unhandled -Wswitch cases of its own. Verified: a sixth enumerator now fails `make grpc-server` with exit 2 and no binary; appending a 14th VoiceTaskKind upstream still fails loaded_model.cpp, so the two pins fire independently; both reverted clean.

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.

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

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

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

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

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

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

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

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

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

mudler's LocalAI [bot]	d8a1e3c2e4	fix(realtime): echo response.metadata on response.created and response.done (#11198) ... response.create accepts a metadata map and ResponseCreateParams has carried the field all along, but triggerResponse never copied it onto the Response it emits, so both terminals went out with metadata omitted. That field is the only thing tying a terminal event back to the response.create that asked for it. Our own doc comment on ResponseCreateEvent says so — "the metadata field is a good way to disambiguate multiple simultaneous Responses" — and it is what makes an out-of-band response (conversation: "none") usable at all: a client running one alongside the spoken conversation has no way to tell its own answer from the conversation's, so it waits for a reply it already received and gave away. Found from the client side: a headless text turn injected into a live session was answered correctly in about a second, and the caller still blocked until its own two-minute timeout because it could not recognise the answer. Carry the map on liveResponse so all three terminals (in_progress, cancelled, completed) report it, and leave it omitted when response.create sent none.

localai-org-maint-bot	9bfd71387b	feat(stores): add Valkey Search vector store backend (#11196) ... * feat: add Valkey Search vector store backend Add a new built-in Go gRPC store backend 'valkey-store' that implements the four Stores RPCs (Set/Get/Delete/Find) against the Valkey Search module (FT.*) using the pure-Go github.com/valkey-io/valkey-go client. It is selected via the existing per-request 'backend' field on /stores, so there is no proto or HTTP API change, and it mirrors the in-memory local-store while adding persistence across restarts and opt-in HNSW. Each vector is a Valkey HASH keyed by hex(little-endian float32); the index is created lazily on first Set (FLAT+COSINE by default), cosine similarity is derived as 1-distance, and namespaces get a collision-resistant token. Includes unit tests (valkey-go mock) and env-gated integration tests against valkey/valkey-bundle, plus build/matrix/gallery wiring and docs.

This also restores Find's dimension check after a restart. - StoresFind treats a dropped/missing index as an empty store (empty result, no error) and clears the stale indexCreated flag, matching local-store's empty-store behaviour. - StoresSet reuses checkDims for its per-key length check so the four RPCs share one dimension-guard implementation. - Add unit tests for FT.INFO dimension recovery, loadIndexState, and the dropped-index Find path.

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

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

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

Richard Palethorpe	49ef40a187	feat(classifier/VAD): support voice control on low power devices (#10804) ... * feat(llama-cpp): route Score through the slot loop Score previously bypassed the slot loop with a direct llama_decode: a conflict guard aborted the whole process if scoring raced generation, the config validator had to reject score alongside chat/completion/embeddings, and every candidate re-decoded the full shared prompt. Add SERVER_TASK_TYPE_SCORE to the (patched) upstream server so score tasks are scheduled like any other slot work: generation and scoring serialize naturally, the shared prompt is decoded once per call, and the slot's prompt cache carries the conversation prefix across calls. Context checkpoints at the score boundary and at the cache-divergence point keep SWA/hybrid/recurrent models (e.g. LFM2.5) from re-prefilling the whole prompt per candidate: warm-turn scoring on a 6-option set drops from ~8s to ~0.5s on a desktop CPU. The conflict guard and the validation split are removed; declaring score with generation usecases on one config is now supported and shares the slot cache. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(realtime): classifier wire types and pipeline config Wire types and YAML config for realtime classifier mode: sessions carry a localai_classifier extension (options with canned replies/tool calls, softmax threshold, normalization, history trimming, fallback modes, and a deterministic wake-word address gate), mirrored by pipeline.classifier in the model YAML and surfaced in the config-meta registry. The localai.classifier.result server event reports the full score distribution per turn. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(realtime): classifier response flow Classifier-mode responses: instead of autoregressive generation, each user turn is prefill-scored against the option list (router.ScoreClassifier prompt/candidate shapes over the Score primitive) and the winning option's canned reply and tool call are emitted through the existing response machinery. Below-threshold turns take the configured fallback (none / canned reply / generate); empty transcripts and unaddressed turns (wake word not mentioned) skip scoring entirely. The scoring probe defaults to the latest user message only — small scorers echo canned replies from prior turns back as the top option otherwise. Built for hardware that can afford prompt processing but not decode: with slot-based Score the option list stays KV-cached across turns, so a turn costs roughly one forward pass over the new words. session_update_error events now carry the validation cause instead of a generic message. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * fix(realtime): bound the VAD tick's scan window and buffer retention The VAD tick loop re-scanned the entire input buffer every 300ms and only trimmed it on zero-segment ticks or commits. Audio that keeps producing segments without a committing pause (steady noise a mic pipeline lets through, music, continuous speech) grew the buffer toward the 100MB cap with each tick rescanning all of it — O(n^2), measured at ~3.3ms of silero per buffered second: past ~90s retained, ticks run back to back and pin ~4 cores until the stream stops. Silero's recurrent state only carries a few hundred ms of context, so rescanning old audio buys nothing. Clip the slice handed to the VAD to the largest silence the commit test can need to measure (server_vad silence window or the semantic eagerness fallback) plus a warm-up margin, and rebase the returned segment times so every downstream consumer keeps whole-buffer coordinates. An open turn whose clipped window is all silence now commits (the silence outran the window) instead of being discarded as no-speech. Independently, retain at most 90s of raw buffer, rebasing the live-feed and EOU cursors on trim — this also bounds the previously unbounded VAD-error path. Turn boundaries are otherwise unchanged: no forced commits, no new coordinator states. pipeline.turn_detection.vad_window_sec can widen the scan window; values below the automatic floor are ignored. The tick body is extracted into vadTick so specs can drive turn detection synchronously (same shape as classifySoundWindow); the babble reproduction that pinned 4 cores now plateaus under 10% of one core.

The YAML threads: knob has been dead config: a tiny VAD model could never opt down from the global pool size. SetDefaults already fills an unset per-model value from the app config, which is the intended precedence; resolve threads through a helper that honors it (explicit threads: 0 still means unset).

Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * perf(llama-cpp): score all candidates in one batched decode One scoring call is now a single SERVER_TASK_TYPE_SCORE task: the slot decodes the shared prefix (prompt + longest common candidate token prefix) once, then forks one sequence per candidate off it (metadata-only for the unified KV cache, copy-on-write for recurrent state) and decodes every candidate's unique tail in one llama_decode. Previously each candidate was its own task that restored the boundary checkpoint and re-decoded its full tail sequentially, paying per-candidate task and decode overhead. The context reserves SERVER_SCORE_FORK_SEQS extra sequence ids (and recurrent-state cells) beyond the parallel slots via the new common_params::n_seq_score_forks. Forking requires the unified KV cache (already this backend's default) since per-sequence streams would shrink n_ctx_seq; an explicit kv_unified:false disables forking and Score calls that need it fail cleanly. Candidates beyond the fork/output budget decode in successive chunks. Wire contract and scores are unchanged: per-token logprobs are stitched from the shared region and the forked tails. Verified bitwise deterministic call-to-call and independent of candidate order (no cross-fork leakage via equal-length candidate swap); ranking matches the per-candidate implementation on the drone battery (winner softmax 0.99996 vs 0.99997), and >16-candidate chunking, prefix-of-another and empty candidates all pass. Measured on a desktop CPU: warm /api/score calls 0.52s -> 0.23s; warm realtime classifier turns 196-303ms.

When the option wins, the slots are filled by a short grammar-constrained completion that continues the exact scoring prompt — rendered by the same cached ScoreClassifier, so the llama.cpp prompt cache is already warm — with the chosen route JSON re-opened at the first slot field. A GBNF grammar pins the field skeleton and frees only the values; temperature 0, a couple dozen tokens at most (~300ms on a desktop CPU for two slots). Slot declarations and hints ride the option descriptions in the shared system prompt, informing scoring and the fill alike at no per-turn token cost. The localai.classifier.result event carries the final arguments and a fill_latency_ms. On inference failure the slots' defaults apply; a slot without a default fails the response (or falls through with fallback.mode: generate). Slot filling requires completion alongside score in the scoring model's known_usecases. Verified end-to-end on the Pi drone demo: "fly forward three meters" in distance mode classifies forward and infers {"distance": 3, "units": "meters"} in ~310ms, and the drone flies exactly 3 units.

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

mudler's LocalAI [bot]	05ff401de8	fix(test): stop the backend-trace specs racing the lossy trace channel (#11146) ... RecordBackendTrace does a non-blocking send onto a 100-slot channel and drops when it is full, so tracing never stalls inference. The payload bounding specs pushed all 200 traces in one tight loop, which overruns that channel on a loaded machine: entries are dropped for good and the Eventually waiting for 200 can never be satisfied, no matter the timeout. CI hit this on master at 0a8a7fbb, settling at 158/200. Feed the traces in chunks of 50, draining after each, so the channel is never overrun and the count stays exact.

LocalAI only binds `output_modalities`, so a client sending the still-common beta field `modalities: ["text"]` has it silently dropped by encoding/json and the session falls back to audio: TTS runs and the client receives large response.output_audio.* frames even though it asked for text-only. Accept `modalities` as an alias on both session.update (RealtimeSession) and response.create (ResponseCreateParams).

Mirrors qwen3-tts-cpp / moss-tts-cpp: dlopen the static-ggml shared library, bind the flat magpie_tts_capi_* C-API via purego (no local C shim needed, the upstream .so exports it directly), and serve the gRPC TTS + TTSStream methods behind base.SingleThread (the C context is not reentrant across synthesize calls). The backend CMakeLists translates the Makefile's -DGGML_{CUDA,METAL,VULKAN,HIP} flags into upstream's MAGPIE_GGML_* toggles (upstream FORCE-overwrites the ggml cache entries from those), pinned to magpie-tts.cpp v0.1.1 (e3f3dd1ebe22b64e7405f93b519f2d1930712568), which statically links ggml into libmagpie-tts.so (ldd shows only system libs). Wires the full registration: backend-matrix.yml (CPU amd64/arm64, CUDA 12/13, Intel SYCL f16/f32, Vulkan amd64/arm64, ROCm, NVIDIA L4T + L4T CUDA 13, and Darwin metal), backend/index.yaml metas and image entries, the root Makefile build targets, the changed-backends backend-filter path mapping, the bump_deps auto-bump matrix, a test-extra per-backend smoke job, the /backends/known pref-only importer entry, the backend capabilities map (TTS + TTSStream, no voice cloning), and the README / compatibility-table docs rows. Verified locally: unit + e2e Ginkgo suites pass against the real q8_0 GGUF (22.05 kHz mono WAV, RMS > 0.01), a live gRPC LoadModel + TTS round-trip returns valid non-silent audio, and the pre-commit gates (make lint, make test-coverage-check) pass, run manually with LOCALAI_TEST_HTTP_PORT overriding the locally-occupied 9090.

mudler's LocalAI [bot]	6584db992f	fix(nodes): never schedule a model onto a node that cannot store it (#11054) ... * fix(nodes): never schedule a model onto a node that cannot store it A worker whose models filesystem was 100% full kept advertising `status: healthy`, stayed a scheduling candidate, was picked to host a 70 GB video model, accepted the staging request, transferred ~17 GB and only then failed: staging .../whisper-large-v3/model.fp32-00001-of-00002.safetensors: upload to node b7bacbf4-... failed with status 500: writing file: /models/longcat-video-avatar-1.5/...: no space left on device The node was at 937G/937G/0-avail. Total elapsed before the truth surfaced: 16 minutes, for a decision that could never have succeeded. The worker health signal only ever proved liveness. `/readyz` (WorkerReadiness/NATSReadiness) checks the NATS link; `status: healthy` in the registry is driven by heartbeat recency. Node capacity carried VRAM and RAM but no disk figure at all, and the router compared model size against VRAM only — nothing anywhere looked at free space on the filesystem that staging actually writes to. Report it, then use it: - Workers now measure the filesystem backing their MODELS directory (not `/` -- staged weights land in the models path, and that mount is very often separate) and report `total_disk`/`available_disk` on registration and on every heartbeat. Free disk moves faster than VRAM under staging traffic, so the per-heartbeat refresh matters. - The SmartRouter drops nodes that cannot store the model before it picks one. The requirement comes from `modelPayloadBytes` -- the same local paths `stageModelFiles` uploads, already computed for the size-derived load budget -- plus a 5% / 1 GiB margin, rather than a fixed percentage of the node's disk. A percentage threshold would take a small-but-usable node out of rotation for models it could hold, and on a homogeneous cluster would strand every node at once. - When no node fits, scheduling fails immediately with an error naming the requirement and each node's free space, instead of picking one and discovering it mid-transfer. Two deliberate non-changes. Low disk does not mark a node `unhealthy`: the check is per model, so a node too small for one model stays a valid target for smaller ones. And `total_disk == 0` means "does not report disk" (pre-upgrade worker, or a failed stat), not "full" -- such nodes pass through untouched so a rolling upgrade never empties the candidate pool. A genuinely full node is distinguishable: non-zero total, zero available. Registry read failures are logged and scheduling continues unfiltered; a database hiccup must not wedge a cluster. Free space is surfaced on the node detail page next to VRAM, since the incident's signature was a node that looked entirely healthy. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude Code:claude-opus-4-8[1m] [Read] [Edit] [Bash] * feat(nodes): make the disk-headroom check operator-controllable The admission check added in the previous commit had no off switch. A scheduler-side veto with no escape hatch is a liability: our size estimate can be wrong (deduplicating or compressing filesystems, a backend that fetches its own weights rather than loading the staged copy), and an operator who hits that has no way out but a downgrade. Add one knob with two surfaces that share a single source of truth: - `--distributed-disk-headroom-check` / `LOCALAI_DISTRIBUTED_DISK_HEADROOM_CHECK` (default true), following the `--distributed-prefix-cache` pattern for a default-on distributed feature. - `distributed_disk_headroom_check` in the runtime-settings registry, so it can be flipped without a restart from `POST /api/settings` and from Settings -> Distributed in the WebUI. Both write `DistributedConfig.DiskHeadroomDisabled`, and the SmartRouter reads that member LIVE on every scheduling decision through a closure over the application config rather than a value snapshotted at construction. Env/CLI sets the boot value, the runtime setting overrides it live, last write wins, and there is exactly one member to read. Snapshotting would have made the runtime toggle a no-op until restart. Disabled means WARN, not SKIP. Selection goes back to ignoring free disk -- byte for byte the pre-check behaviour -- but the check still runs, and when it would have rejected every node it says so, naming the knob that suppressed it. Going quiet when switched off would reproduce the exact condition that made the original incident expensive: a cluster doing something that could not work and saying nothing. Disabling is also logged once at startup. Warning only on the total-rejection case keeps it actionable rather than chatty on a heterogeneous cluster. Also fixes a false positive in the check itself: shared-models mode (LOCALAI_DISTRIBUTED_SHARED_MODELS) stages nothing at all -- every node already mounts this models directory at this path -- so demanding the full checkpoint size of free space per node would have rejected a cluster that needs no new bytes. The check is skipped there entirely.

mudler's LocalAI [bot]	f317da7c0f	fix(galleryop): make admitted operations queryable and survive a failed op (#11044) ... Two lifecycle defects observed on a 2-replica distributed cluster. The install endpoints mint a job UUID, hand the operation to an unbuffered channel, and answer HTTP 200 immediately. The gallery worker is a single goroutine that processes operations serially, and the first status write happens inside modelHandler/backendHandler — i.e. only once the worker actually starts the work. An operation queued behind a running install therefore had no status at all: GET /models/jobs/<uuid> answered "could not find any status for ID" and GET /models/jobs did not list it, so the endpoint reported success for work nothing could observe. On the paths that sent directly rather than from a goroutine, the same unbuffered channel blocked the HTTP handler for the whole duration of the in-flight install, which is how a replica came to accept no /models/apply at all while /readyz stayed green. Admission now goes through EnqueueModelOp/EnqueueBackendOp, which publish a "queued" status before handing the operation over, so a job ID is queryable from the instant it is handed out. Delivery selects on the operation's context, so cancelling a still-queued operation releases the delivery goroutine instead of stranding it on a send that will never be received, and an operation the worker never accepts becomes a terminal failure rather than a silent leak. The worker also had no panic containment. A panic in any handler propagated out of the single consumer goroutine and killed the process, taking every queued operation with it; it is now contained to the operation that caused it. The two ignored galleryStore.Create errors are logged, and the model and backend delete endpoints now run under the same ID they hand back — they previously ran under an empty ID and returned a status URL for a job that could never have a status. Second, an operation orphaned by a controller replaced mid-download kept reporting phase=downloading, processed=false, error=none while nothing was downloading. The PostgreSQL side does recover on its own (FindDuplicate ignores rows untouched for 30 minutes and CleanStale marks them failed), but the reaper only ever corrected the database. The in-memory statuses map that GET /models/jobs/<id> and /api/operations actually read was never corrected, so every replica kept serving the frozen tick indefinitely. ReapStaleOperations now reconciles the in-memory copy with the reap. Note that operation ownership is still not tracked: gallery_operations has a FrontendID column that nothing writes, so a live operation and one whose owner died are distinguished only by a 30-minute staleness timeout. Narrowing that window needs a lease/heartbeat mechanism and is out of scope here.

mudler's LocalAI [bot]	ff299df453	perf(http): gzip responses, cache hashed assets, bound the trace endpoints (#11056) ... Three measured HTTP-layer regressions on a live deployment, fixed together because they all shape the bytes on the wire. 1. No compression. The server sent no Content-Encoding regardless of what the client asked for, confirmed with curl straight at 127.0.0.1:8080 so it was not an ingress artefact. Adds gzip middleware, on by default and configurable via LOCALAI_DISABLE_HTTP_COMPRESSION and LOCALAI_HTTP_COMPRESSION_MIN_LENGTH (default 1024 bytes so tiny bodies are not wastefully wrapped). Streaming routes are skipped explicitly: an SSE Accept header, a WebSocket upgrade, and the completion / SSE / log-tail path prefixes, because whether a completion request streams is decided by the request body, which the middleware runs too early to see. Already-compressed formats (woff2, png, mp4, ...) are skipped too; gzip made those marginally larger. Measured over the embedded React build: JS+CSS 2815 KB raw to 808 KB gzipped (3.48x). 2. No cache headers on content-hashed assets. Vite hashes the filenames, so a given /assets/ URL can never change content, yet they shipped with no Cache-Control, ETag or Last-Modified, and the browser re-fetched the whole bundle on every navigation with no conditional request available. /assets/* now carries public, max-age=31536000, immutable. index.html stays no-cache so a deploy is picked up, and the unhashed locale JSONs get a short TTL rather than the immutable one. 3. Unbounded trace endpoints. /api/traces returned 21,033,606 bytes in 4.65s and /api/backend-traces 3,471,682 bytes in 1.50s, and the admin UI polls both every few seconds. The ring buffer holds up to 1024 entries, each embedding full input_text payloads. Both list endpoints now take limit / offset / full, default to 50 entries, and strip the heavy fields (request and response bodies plus headers for API traces, body and data for backend traces) unless full=true. Every trace gets a process-lifetime ID and GET /api/traces/{id} and /api/backend-traces/{id} serve the full record, which is what the UI fetches when a row is expanded. The list body stays a JSON array; paging metadata rides in X-Total-Count, X-Trace-Offset and X-Trace-Limit. Reproducing the live shape in a test, the polled payload goes from 21,131,097 bytes to 7,201 bytes.

The num_ctx clamping specs added in #11032 construct their fixture with `config.ModelConfig{ContextSize: &existing}`, but ContextSize is not a direct field of ModelConfig: it belongs to LLMConfig, which ModelConfig embeds inline. Go allows reading a promoted field but not setting one in a composite literal, so the test file has never compiled: helpers_internal_test.go:33:31: unknown field ContextSize in struct literal of type "github.com/mudler/LocalAI/core/config".ModelConfig This broke `make lint` on master from bf19758e0 onward, and because the typecheck failure takes down the whole package it also reds tests-linux and tests-apple on every PR branched after that commit. Use the same literal form the rest of the tree already uses for this field (see core/backend/options_internal_test.go). Worth noting the specs were not merely uncompiled but inert: #11032 is a DoS fix (an unauthenticated client raising the context ceiling drives KV-cache allocation), and its regression guard was never actually running. Verified the restored specs are functional by stubbing out the ceiling clamp, which fails the "does not let an oversized num_ctx raise an existing context ceiling" spec as intended.

mudler's LocalAI [bot]	54f531f452	fix(mcp): bound MCP session connect so an unreachable server can't hang the widget (#10880) (#10884) ... Establishing an MCP session held the session-cache mutex across client.Connect with no per-connect timeout. An unreachable remote server (bounded only by the 360s httpClient timeout) or a stdio server whose initialize handshake never completes therefore blocked the caller and, because the mutex was held, every other MCP request for that model too. In the UI this shows up as the MCP "Servers" widget spinning forever. It is most visible for cloud-proxy models: their chat path bails out before the MCP tool block, so it never warms the session cache in the background. The widget's /v1/mcp/servers/<model> call is then the first and only code that connects synchronously, in the request foreground. The session, once established, stays bound to the shared context (it is cancelled later via the cached cancel func on eviction/shutdown), so we can't pass a WithTimeout context to Connect: firing the timeout would tear a healthy session down, and cancelling the shared context would also kill sibling servers that already connected. Instead connectMCP runs Connect on the shared context in a goroutine and stops waiting after the discovery timeout, returning an error for that one server without disturbing the others. A stalled goroutine is reaped when the model's sessions are cancelled. Applied to both SessionsFromMCPConfig and NamedSessionsFromMCPConfig.

mudler's LocalAI [bot]	d7e04dcc32	fix(openresponses): make responses visible and cancellable across replicas (#11000) ... In distributed mode the Open Responses store is process-local: a sync.OnceValue over a map behind an RWMutex. With several frontend replicas behind a round-robin load balancer, every request that lands on a replica other than the creator misses. Measured on a live 2-replica cluster (#10993): the same response id returns 200 on the creating replica and 404 on its peer, and a cancel on the peer returns 404 without ever invoking CancelFunc, so generation runs to completion on the other replica while the caller is told the response does not exist. previous_response_id chaining fails through the same lookup. Split the state by what can actually cross a process boundary: - Replicated: response metadata (request, response resource, owner, expiry, stream/background flags) via syncstate.SyncedMap, the same component finetune, quantization and agent tasks already use. A local miss in Get/FindItem now falls back to it and returns a read-only remote view, so polling and chaining resolve on any replica. - Delegated: cancellation. context.CancelFunc is a function pointer and exists only in the creating process, so a cancel that lands elsewhere is broadcast on responses.<id>.cancel and applied by whichever replica holds the function. The broadcast is fire-and-forget rather than request/reply: if the owner crashed or was scaled down nobody answers, and the handler must not block on a reply that will never come. The replicated status moves to cancelled either way, which is truthful, since a dead owner's generation died with its process. - Refused: streaming resume. The resume buffer is a byte log plus a live notification channel and cannot be replicated without shipping every token over the bus. A resume that reaches the wrong replica now returns HTTP 409 naming the owning replica via the new ErrResponseNotLocal, instead of an empty event list that looks like a finished stream. It is deliberately distinct from ErrOffsetLost, which means the owner's buffer evicted the requested events.

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.

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.

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 d0d441bb4. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): select model variants by hardware fit, not authored order Gallery entries could already carry a list of alternatives, but selection was an authored, ordered, first-match policy: every candidate declared a `capability` string and the VRAM floors had to descend in a hand-tuned order. That pushed hardware knowledge onto whoever edits the gallery and made ordering load-bearing, so a reordered list silently changed what users installed. None of it was necessary. SystemState.IsBackendCompatible already derives hardware support from a backend name alone: it knows MLX and metal are Darwin-only, CUDA is NVIDIA-only, ROCm AMD-only, SYCL Intel-only. Selection can read that instead of asking authors to restate it. Authoring is now just a list of names: - name: qwen3.6-27b min_memory: 4GiB variants: - model: qwen3.6-27b-mlx-8bit - model: qwen3.6-27b-gguf-q8 min_memory: 28GiB and all the intelligence moved into the selector. Given a host it drops the variants whose backend cannot run here, drops those whose known memory requirement exceeds what the host has, and takes the LARGEST of what is left, because a bigger footprint is a higher quality quantization of the same model. A variant of unknown size is kept, since nothing proves it does not fit, but it ranks last so a proven fit always beats a guess. An explicit pin still wins outright, and if nothing survives the entry installs its own payload: the base always installs, this never refuses. Available memory is VRAM when a GPU was detected and system RAM otherwise, read through xsysinfo so a cgroup limit is honored and a container gets its own limit rather than the node's RAM. Capability disappears entirely, from the types, the schema and the lint. VRAM and RAM collapse into one `min_memory`, because a model's footprint is roughly the same wherever it lives and one figure is compared against whichever applies. The lint rules about ordering, the capability vocabulary and floor relationships are deleted with the hazards they described; what remains is that every variant names an entry that exists and does not itself declare variants, plus that any memory figure actually parses. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * gallery: size model variants with a live probe, drop the nightly denormalizer Selection needs each variant's size to decide whether it fits and to rank largest-first. That figure was written into the index by a nightly job, which made the gallery carry a derived value that could drift from the entry it was derived from. Derive it at install time instead. pkg/vram already sizes a model without downloading it, and the gallery UI already uses it: a remote GGUF header range-fetch, then an HTTP HEAD for the content length, then any declared size:. It caches its results, so reuse it rather than writing a second probing path. A probe failure must never fail an install, so an unprobeable variant is treated as unknown: it survives the memory filter, because nothing proves it does not fit, and it ranks last, so a known-good fit always beats a guess. If every probe fails, selection still terminates on the base entry. The probe is injected through ResolveEnv rather than called directly, for the same reason the backend compatibility check is: specs pin an exact size, or an exact failure, without reaching the network. With that in place three things are dead weight and go: - The nightly job and the fields it populated. Variant.Backend was redundant because the backend is resolved live from the referenced entry during selection, and Quantization was display-only that nothing read. - min_memory on the base entry. The base always installs and its floor could only warn, so it could not change any outcome. - The lint rules and schema entries for both. min_memory on individual variants stays, as the override for when the probed size is wrong. An authored figure now suppresses the probe entirely rather than merely outranking it, so it costs no round trip. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): expose model variants for selection over API, CLI and MCP A gallery entry may carry `variants:`, alternative builds of the same model. Selection already worked at install time, but nothing could see what an entry offered or ask for a specific build, so the feature was undrivable. Listing: `GET /api/models` now reports `variants` and `auto_variant` for the entries that declare variants. Each variant carries its resolved backend, its measured size and whether it fits this host. `auto_variant` is what installing without a choice would pick right now. The new gallery.DescribeVariants runs the same variantOptions + SelectVariant pass the installer runs, so the reported default cannot drift from what installing actually does, and HostResolveEnv is extracted so both derive the host and share pkg/vram's probe cache from one place. Performance: an entry that declares no variants returns early without touching the probe, so the ~1280 ordinary entries cost exactly what they cost before. Selection: `variant` is accepted on POST /models/apply, as a query param on POST /api/models/install/:id, on the gallery apply file/string request, as `local-ai models install --variant`, and as a parameter on the install_model MCP tool (both the httpapi and inproc clients). Empty means auto-select. An unknown variant name now fails the install naming what was requested. This closes a real hole: an entry declaring no variants short-circuits before selection runs, so a requested variant was previously dropped silently and the install reported success. startup.InstallModels ends in a variadic model list, so install options could not be appended to it; InstallModelsWithOptions is added alongside and InstallModels delegates to it. No caller signature changed. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): drop the redundant variant min_memory field Variant.MinMemory was an authored override for when the live probe misreads a variant's footprint. It duplicated an existing field: probeEntryMemory already passes the entry's declared size: into EstimateModelMultiContext, whose cascade prefers that declared size over its own guesswork. Correcting size: on the referenced entry fixes the figure for every consumer rather than only for variant selection, so min_memory shadowed the right answer. A variant is now nothing but a name. Its effective size is exactly the probe result, and an unknown stays unknown: it survives the filter and ranks last. EffectiveMemory loses its error return along with the field. The authored string was the only thing that could fail to parse, so the error had no remaining source and was propagating dead nil-checks through SelectVariant, DescribeVariants and the pin warning. Selection behaviour is unchanged. The specs covering probe-derived sizing, ranking, filtering, the unknown-size path, pin recall, entry/variant metadata split and deep-copy isolation all survive; the three install specs that needed a definite size now declare it through the referenced entry's own size:, which exercises the documented escape hatch directly. gallery/index.yaml is untouched: no entry ever carried the key. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): rank the entry's own build against its variants Variant selection pulled the declaring entry's own payload, the base, out of the candidate set and consulted it only once every declared variant had been rejected. Two real failures followed. A variant whose size the probe cannot determine deliberately survives the memory filter, because nothing proves it does not fit. As the only survivor it then won outright on any host, however small: a 2GiB machine installed an unmeasured variant in preference to the 4GiB build the entry itself ships, with no warning. 241 of the 1280 current index entries carry no files and no size, which is exactly that shape. "Largest wins" also broke whenever the base was the largest. An author writing a Q8 entry that offers a Q4 downgrade for small hosts, a natural shape that nothing in the lint, schema or docs discourages, had the Q4 installed on every large host instead. Make the base an ordinary participant. It is still exempt from both filters, so selection always terminates on something installable, but it is now ranked against the variants: a proven fit first and largest, then the base, then any variant whose size nothing could measure. Both failures disappear together. The base is probed for its size accordingly, which it was not before, because an unsized base would lose every contest to an unmeasurable variant. FellBackToBase is kept but narrowed to "no declared variant survived", rather than "the base was chosen", since the base now also wins on merit and that is not worth warning about. A recalled variant pin also became a permanent install failure. A pin the caller supplies on this request must stay fatal, but one recalled from ._gallery_<name>.yaml can be invalidated by any later gallery edit, and failing on it turned one rename into a model that could never be reinstalled or upgraded again short of deleting a dotfile the user has never heard of. A stale recalled pin is now dropped with a warning naming it, and selection runs as if it had never been recorded. Also drop the last textual reference to two abandoned designs from the DetectedCapability comment, correct the documented variants JSON example, which showed a memory_bytes of 0 that omitempty makes impossible, and remove an em dash from the install skill. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): budget variant memory from RAM when a GPU reports no VRAM Variant selection read its memory budget from VRAM whenever a GPU capability was detected, and from system RAM only when none was. Apple Silicon satisfies the first branch and fails the premise: arm64 macs report the metal capability unconditionally, without probing anything, while TotalAvailableVRAM has no discrete VRAM pool to find and returns zero. The budget therefore came out as zero on every Mac. Zero drops every variant carrying a known size, so the base build was installed on all of them however much memory the machine had. The feature was inert on the platform, and silently: falling back to the base is a legitimate outcome, so nothing looked wrong. Take VRAM only when it is actually a number, and fall back to RAM otherwise. On a unified-memory host RAM is not an approximation of the budget, it is the budget, since the GPU shares it. A discrete GPU whose VRAM could not be read also lands on RAM, which overstates what the card holds but understates nothing the host has; the previous zero understated both. An unreadable RAM figure still yields zero and still installs the base, so a genuinely unknown host is not talked into a larger download. This is what turned tests-apple red: "installs a fitting variant's payload under the entry's own name" asserts on selection, and the runner resolved to the base because its budget was zero. The added specs pin the branch directly rather than relying on a macOS runner to notice again. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): add a model variant picker to the models gallery PR #10943 shipped the server side: a gallery entry may declare `variants:`, `GET /api/models` attaches `variants` and `auto_variant` to declaring entries, and `POST /api/models/install/:id` accepts a `variant` query parameter. Nothing in the UI consumed any of it, so the feature was not reachable from the browser. This wires it up. modelsApi.install takes an optional second argument and appends an encoded `?variant=` only when one is given, so every existing call site keeps sending exactly the request it sent before. On the models table, an entry that declares variants gets a split button. The primary Install still installs the auto-selected build, because auto is the default and the point of the feature; the chevron opens a menu for a deliberate override. It follows the Backends.jsx precedent: one shared Popover re-anchored per row, rendering .action-menu items, which brings Escape, outside-click and focus return along with it. An entry that declares no variants renders exactly as it did before. A variant that does not fit is dimmed but stays selectable, since the server honors an explicit choice with a warning rather than refusing it. memory_bytes is omitempty on the wire, so an absent key means the size is unknown and never zero. A single helper guards both the menu and the detail row, because formatBytes would otherwise render a falsy value as "0 B", which reads as "needs nothing". The expanded detail row gains a Variants section listing each build's backend, size, whether it fits, which is the entry's own build, and which one auto-selection would pick, built from the existing DetailRow helper and .badge classes. Eight Playwright specs cover the picker, including that plain Install sends no variant parameter and that choosing one sends it. One pre-existing assertion was scoped with .first(): the Variants section legitimately adds more llama-cpp badges to the detail row, which tripped strict mode. UI line coverage 49.42% -> 49.36% against a 40.0 baseline and 0.8pp tolerance; branch coverage rose 72.04% -> 72.66%. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): describe model variants from a companion endpoint Variant description probes each referenced entry's weight files over the network: an HTTP HEAD plus a ranged GET, serial, five seconds per probe with no aggregate deadline. Running it inline in GET /api/models made one listing cost (entries x variants) round trips. The Manage page fetches with items=9999, so at 200 declaring entries that is ~1000 serial probes, minutes of a blocked handler and gigabytes of range traffic for a single page load. Only one entry declares variants today, but the feature exists so that many will. Follow the precedent already set for VRAM estimates. The listing now reports only has_variants, a length check on loaded metadata that touches nothing, and GET /api/models/variants/:id returns the description for one entry, mirroring estimate/:id in route shape, auth and error handling. DescribeVariants itself is unchanged; only its caller moved. The picker fetches lazily at the two points where a user asks to see variants, opening the split-button menu and expanding the detail row, and caches per entry for the page session. An entry declaring no variants issues no request at all. A spec counts real HTTP hits on the weight files, so it goes red if description becomes reachable from the listing path again through any caller. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): filter the model gallery to entries that declare variants The gallery is heading towards showing parent entries and hiding the individual builds they reference, so a user sees one row per model rather than six quantizations of it. Adoption is a single entry today, so defaulting to that would leave a one-row gallery. This ships the migration-phase inverse instead: the default is untouched, and a toggle narrows the list to only the entries that declare variants. It previews the end state and changes nothing until someone asks for it. The filter is server-side, next to term/tag/backend/capability and above the pagination arithmetic. The listing paginates at 9 items, so narrowing on the client would leave totalPages and availableModels describing the unfiltered set and hand the user empty pages. It selects on HasVariants(), which reads already-loaded metadata, so it issues no variant probes. The parameter is named has_variants after the listing field it selects on, and is compared against "true" like the other boolean query params (all_users, save_checkpoint), so has_variants=false reads as absent. With it omitted the response is byte-for-byte what it was before. The control is the shared Toggle component, matching the fitsFilter toggle already on this page: same wrapper class, same icon and label shape, same localStorage persistence. Unlike fitsFilter it resets to page 1 on change, which a server-side filter has to do. Stacking the toggle with a tag or backend filter easily yields nothing while one entry declares variants, so the empty state now names the variants filter as the cause rather than leaving a user to conclude the gallery is broken.

Full-description areas now render through renderMarkdown (marked + DOMPurify), matching how Backends.jsx and the Manage detail panels already handle the same content: - Models.jsx expanded detail row - VoiceLibrary.jsx voice detail header The truncated one-line previews must not render block Markdown: a leading "#" would become an <h1> and wreck the row height and rhythm. They get a new stripMarkdown() helper instead, which reduces Markdown to a single line of readable plain text. It is used for the cell text and for the title tooltip, since a tooltip full of "[](url)" is no better than a cell full of it: - Models.jsx gallery table description cell - Manage.jsx model and backend resource-row descriptions stripMarkdown walks marked's lexer output rather than running regexes over the source, so what it strips is by construction what renderMarkdown would have rendered, and it needs no new dependency. Output lands in JSX text nodes, so React escapes it; no new dangerouslySetInnerHTML beyond the two full-description sites, both of which run DOMPurify. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ui): strip Markdown from the backends table description cell Commit b35d630cf fixed this for gallery models but left the Backends admin page with the same asymmetry: its detail panel renders the description through renderMarkdown, while the collapsed table row dumped the raw gallery string into both the cell body and the title tooltip. That is user-visible. 40 of the 949 entries in backend/index.yaml carry Markdown - insightface uses inline code backticks, others use lists and links - and backend descriptions also contain embedded newlines, so the one-line cell showed literal syntax. The cell now runs stripMarkdown over the description once and uses the result for the text and the title, matching Models.jsx and the ResourceRowDesc component in Manage.jsx. The '-' placeholder is preserved, and now also fires when a description reduces to nothing after stripping. The detail panel is untouched and no new dangerouslySetInnerHTML is introduced: stripMarkdown output lands in a JSX text node, so React escapes it. Three Playwright specs cover it: a description with a heading, inline code and a link renders as clean text with no literal syntax and no block element in the cell, the title tooltip carries the same stripped text, and a backend without a description still shows the placeholder. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * ui(models): polish the variant detail view and scope rendered Markdown The gallery detail pane rendered every field through the same two-column label/value row, including the description. Multi-paragraph prose in a value cell ran eight rows tall at the top of the pane on a ~1200px measure, breaking the grid's rhythm exactly where the eye enters. Move it into its own full-width block above the table, capped at a 68ch measure, keeping the label. Rendered Markdown had no scoped typography anywhere in the app, so a description opening with `#` inherited the browser default 2em inside a 13px surface while a `##` further down was indistinguishable from body text. Add a reusable .markdown-body block mapping h1-h6, paragraphs, lists, links, code, blockquotes, images and tables onto the existing type scale, and apply it to every renderMarkdown() consumer: the models detail, the backends detail, both Manage details and the voice library detail. Rebalance the variants list so the name leads. Backend and size drop from badge/secondary weight to muted metadata; the FITS badge goes entirely, since it was true of nearly every row and so said nothing, while the variant that does not fit keeps a warning badge and a dimmed name. AUTO-SELECTED stays marked because it answers what a plain Install produces. Rows share the parent's grid tracks via subgrid so name, backend, size and status line up down the list instead of raggedly following name length. Finally, make each variant row actionable. It looked like a list of choices but was inert text, with per-variant install hidden behind the split-button chevron elsewhere; each row is now a button onto the existing handleInstall(modelId, variant) path, with hover, keyboard focus and a disabled state while an install is in flight. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): collapse the listing to one row per model The listing supported has_variants=true, which narrowed to entries that DECLARE variants. With adoption at three entries that showed three rows, which is useless; it was always a placeholder. Replace it with the view that is actually useful: the deduplicated gallery. Show every entry installable in its own right and nothing twice, which means the parents plus every entry nobody references, and hide only the builds another entry already offers as a variant, since those are reachable through their parent. The parameter is renamed to collapse_variants accordingly: the filter is no longer a predicate on a row's own metadata but a view over the whole gallery. Default stays off, so the response with the parameter absent is unchanged. VariantReferencedIDs never reports an entry that declares variants of its own, so parents are always visible. That guarantees every hidden entry has a visible entry offering it, and no chain can strand a row. Variant resolution already refuses to install such a reference, but the listing has to stay coherent in the presence of a gallery that has one rather than silently swallowing entries. Self-references and dangling references hide nothing. The referenced set is computed over the whole gallery rather than over what the other filters left, so an entry is hidden because a parent offers it and never because of what the user searched for. The pass is over metadata already in memory: it resolves nothing over the network and triggers no variant description or size probe, so the listing's zero-probe contract still holds. The UI toggle keeps its behaviour (persistence, page reset, clear filters) and becomes "One row per model", which says what the user gets. Its localStorage key moves too, since the stored value meant a different filter. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): show the collapsed model listing by default The gallery listing is what a user reaches for to answer "what can I install". Answering that with several rows for the same model, one per build, makes the reader do the deduplication the collapsed view already does, so the collapsed view is the one to land on. The UI now asks for collapse_variants=true unless the toggle says otherwise. The server default is deliberately untouched: a request with the parameter absent still returns the full listing, because other API clients depend on that response and collapsing it under them would be a breaking change. Opting out omits the parameter rather than sending false, so it asks for exactly the listing everyone else gets. The stored preference changes vocabulary from '1'/'0' to 'on'/'off'. The previous build wrote it from an effect that runs on mount, so a stored '0' recorded that the page had been opened rather than that anyone chose the expanded view, and honouring it would pin every earlier visitor to a default they never picked. Only the new vocabulary counts as a choice; a legacy '1' meant the collapsed view and is what the new default gives anyway, so no earlier deliberate choice is lost. Collapsing being the default also changes what the empty state may say about it. An opted-into filter can be named as the cause of an empty result; a default cannot, so the filters keep the top line and the collapsed view drops to a hint below it, shown only once filters are narrowing the set. For the same reason "Clear filters" now restores the collapsed default instead of switching it off, and the toggle alone no longer counts as a filter worth offering to clear. The label stays "One row per model": it describes the view the user is looking at rather than an action, so it reads the same whether it is opted into or out of.

The parent is the bare-named entry wherever one exists, so nothing changes about what any existing entry installs. Ranking already selects the largest fitting build regardless of which entry is nominally the parent, so the parent only decides the pathological case where nothing fits. For the ten families that have no bare-named entry, the smallest build is the parent, since that is the one that has to install when nothing fits. Grouping was verified against the actual model filenames rather than the entry names alone. Different parameter sizes, languages, finetunes, and products that merely share a name prefix are left as separate rows: the qwen3.6 APEX and pi-tune finetunes, the DFlash and MTP speculative-decoding pairings, English-only versus multilingual Whisper, the QAT versus non-QAT Gemma 4 weights, and the abliterated FLUX build are all distinct models. Six parents define YAML anchors that other entries pull in with a merge key, which would have handed their variants to every merging child. For the two depth-anything anchors that would have made fourteen unrelated entries advertise the base model's builds as their own. All 26 merging children therefore carry an explicit empty variants list, which overrides the merged key and is equivalent to the key being absent. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): rank model variants by host backend preference Variant auto-selection filtered candidates by whether their backend can run on the host, then ranked the survivors by size alone. The backend never influenced the choice beyond that gate, so a Mac offered both an MLX build and a llama.cpp build kept neither filtered and installed whichever was larger, leaving the native accelerated runtime unused. The same held for CUDA against CPU on NVIDIA and ROCm against Vulkan on AMD. Rank by the host's backend preference between the fit tier and size: fit stays a filter, preference decides among the builds the host can equally hold, and size still separates builds on equally preferred runtimes. The preference data stays in one declarative table in pkg/system, now read by a prefix lookup instead of a switch, so adding a capability or reordering one host's runtimes is a one-line edit and the gallery's ranking code carries no per-backend branching. MLX joins the metal rule ahead of metal itself, which is inert for the existing alias-resolution consumer because no alias group holds a candidate named for mlx. An unrecognised backend, an unrecognised capability and an absent preference list all collapse to the previous size-only ordering rather than erroring or dropping candidates. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): rank variants by engine name, not backend build tag Variant auto-selection ranked candidates with SystemState.BackendPreferenceTokens, but that function and the variant ranker speak different vocabularies. BackendPreferenceTokens returns BUILD TAGS ("cuda", "rocm", "sycl", "vulkan", "metal", "cpu"). It exists to match installed backend build directory names like "llama-cpp-cuda-12" during alias resolution in ListSystemBackends. Variant ranking instead matches a gallery entry's `backend:` value, which is an ENGINE NAME: "llama-cpp", "vllm", "vllm-omni", "sglang", "mlx" and the rest. No engine name in gallery/index.yaml contains "cuda", "rocm", "sycl" or "vulkan". preferenceRank matches by substring, so on an NVIDIA host the tokens [cuda, vulkan, cpu] matched neither "llama-cpp" nor "vllm", every candidate scored identically and size alone decided. The NVIDIA, AMD, Intel, darwin-x86 and vulkan rules were all inert. Only metal appeared to work, and only because the token "mlx" happens to equal an engine name. The mismatch does not error, it silently deletes the feature. Separate the two vocabularies. backendBuildTagPreferenceRules keeps the build tags and its original output for every capability, including metal, whose "mlx" token is removed again; its alias-resolution consumer is byte-identical to before. engineNamePreferenceRules is new, holds engine names, and is read by the new EnginePreferenceTokens, which HostResolveEnv wires into the renamed ResolveEnv.EnginePreference. Both tables sit adjacent under one block comment naming each vocabulary and each consumer, and share one lookup helper so their semantics cannot drift. On NVIDIA the order is vLLM, then SGLang, then llama-cpp: vLLM is the throughput engine and a model published with a vLLM build is published that way because that build is the one worth running. AMD and Intel get the same order, since rocm and intel builds of both serving engines ship. Metal prefers mlx over llama-cpp. Vulkan prefers llama-cpp, the only LLM engine with a Vulkan build. darwin-x86 and unknown capabilities are deliberately absent rather than guessed at, degrading to the size-only ordering that predates preference. preferenceRank stays generic and names no engine and no capability, so adding a runtime remains a one-line table edit. Specs pin the NVIDIA and metal rules through the live table and the real HostResolveEnv wiring, so emptying the engine table or wiring the build tag source back in both go red. A regression table asserts BackendPreferenceTokens' original output per capability, and mirrored locks assert neither table carries the other's vocabulary. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs: record that variant selection ranks by engine before size A gallery entry can now declare variants, and selection ranks the builds a host can run by engine preference before size. Nothing told a contributor adding a backend that engineNamePreferenceRules exists, so a new engine would silently rank below every known one and lose to whatever build happened to be larger on hosts where it should have won. Document the step where a backend is added, warn against the sibling backendBuildTagPreferenceRules table (build tags, not engine names: the wrong table matches nothing, scores every candidate equally and disables the preference without erroring), and index it from AGENTS.md. Fix the authoring and user docs, which still claimed the largest surviving build wins. An author grouping builds under one entry has to be able to predict what a user gets, and size alone no longer decides it. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(cli,mcp): describe variant auto-selection as preference before size The CLI flag help and the install_model tool schema both still said auto-selection takes the largest build that runs. Ranking now puts engine preference ahead of size, so on NVIDIA a vLLM build wins over a larger llama.cpp one. An assistant reading the old schema would tell users the wrong thing. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): prefer llama.cpp over GPU serving engines on hosts with no GPU engineNamePreferenceRules had no row for the "default" capability, which getSystemCapabilities() returns both when no GPU is detected and when a GPU is present but under the 4 GiB VRAM floor. A missing row yields an empty preference list, which preferenceRank reads as "score everything equally", collapsing variant selection to size alone. That would be harmless if the hardware filter dropped GPU serving engines on such a host, but it does not. IsBackendCompatible derives support from the engine NAME, and "vllm" and "sglang" contain none of the darwin, cuda, rocm or sycl tokens it keys on, so they fall through to its closing "return true". A vLLM variant therefore survives on a CPU-only box and wins whenever its build is the larger of the two on offer: the machine installs vLLM in preference to llama.cpp. darwin-x86 had the identical hole. It was documented as a deliberate omission because nothing accelerates on an Intel Mac, which is true about acceleration and wrong about consequence: with every engine tied, download size decides. Add rows for both putting llama-cpp first. The GPU engines are enumerated behind it rather than left unmatched: an unmatched engine already ranks below every listed one, so llama.cpp would win either way, but unmatched engines also tie with each other and let size decide among them. Naming them fixes that order. MLX is left off the darwin-x86 row on purpose so it ranks last, since IsBackendCompatible admits darwin-tokened engines on that capability even though MLX needs Apple silicon. Preference orders survivors and never filters, so a model published only as a vLLM build is still installed on a host with no GPU; there is a spec for it. Surveyed every other value getSystemCapabilities() can return. nvidia, amd, intel and vulkan have rows; the l4t and cuda-refined values reach the nvidia row by prefix; "apple" and "" cannot reach the vendor fallthrough because the darwin and no-GPU branches return earlier. default and darwin-x86 were the only live holes. BackendPreferenceTokens and its build-tag table are untouched, and preferenceRank stays generic, naming no engine and no capability. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * gallery: prefer speculative-decoding builds when they fit Rank serving features between engine preference and size, so a host that can hold a DFlash or MTP build of a model's weights installs it instead of the plain build. Both answer faster for the same output, so whenever one survives the filters there is no reason to take the plain build. Precedence is now fit, then engine, then serving feature, then size. Engine outranks the feature deliberately: a serving feature makes the right engine faster, it does not make a wrong engine right, so a plain vLLM build still beats a DFlash llama.cpp build on NVIDIA. Fit outranks both, and a drafter pairing is strictly larger than the plain build, so the existing size filter drops it on a host too small for it before this axis is consulted. The order lives in a third preference table in pkg/system, alongside the build tag and engine name tables. It is the odd one of the three: not keyed by capability, because no hardware prefers a plain build over an equivalent faster one, and matched against whole segments of a gallery ENTRY NAME rather than as a substring of a backend value. Nothing on a gallery entry declares a serving feature, and tags are not a usable substitute: gemma-4-e2b-it:sglang-mtp carries an mtp tag while ornith-1.0-9b-mtp and qwen3.6-27b-nvfp4-mtp carry none. Entry names are author-supplied free text, unlike the closed engine vocabulary, so a short marker can turn up inside an unrelated word and whole segment matching is what keeps smtp-assistant from ranking as an MTP build. The block comment over the tables now documents all three together and states what each is matched against; the ranking code names no feature, so adding one stays a one-line edit to the table. 29c49203b rejected these entries as serving configurations rather than alternative builds of the same weights. The definition is now "alternative ways to serve the same model", which includes them, so regroup 14 entries under 12 parents. Judged by the files each entry points at: the qwen3.6, qwen3.5, qwen3 and deepseek pairings are the base GGUF plus a drafter, the gemma-4 QAT MTP entries are the same QAT weights at a different quantization plus an MTP drafter, and the two sglang MTP entries describe themselves as the same model served with speculative decoding. Left separate: qwen3.6-27b-mtp-pi-tune, a finetune with its own weights, and every entry whose base model LocalAI does not ship as its own row, which is the whole Qwopus line plus gemmable-4-12b-mtp, mimo-7b-mtp:sglang and qwen3.5-4b-dflash. None of the twelve parents defines a YAML anchor, so no variants key can leak through a merge key and no empty override was needed this time. The index was edited by line insertion only.

Restoring an env var is exactly the place a silent failure leaks state into the next spec, so assert on it rather than suppressing the linter. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): make the mtp tag authoritative for serving-feature ranking Variant auto-selection ranks survivors by fit, then engine, then serving feature, then size. The serving-feature lookup read only whole alphanumeric segments of a variant's entry name, because tags were inconsistent: every dflash entry carried a dflash tag, but only 7 of 20 MTP entries carried an mtp tag. Tag the 13 untagged MTP entries, then teach the lookup to read tags as well as names. A tag is now the authoritative signal and is compared whole and case-insensitively, which is safe precisely because a tag is a deliberate declaration rather than free text: there is no word-inside-a-word failure mode, so the segment splitting the name half needs is unnecessary there. The name check stays as a fallback rather than being replaced. Switching to tags only would have regressed the six already-grouped entries on the day it shipped, and would depend on tagging discipline that does not exist yet. The lookup still names no feature, so adding one remains a one-line edit to servingFeaturePreferenceTokens. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): make a declared tag the sole serving-feature signal Variant auto-selection ranks survivors by fit, then engine, then serving feature, then size. The serving-feature lookup recognised a speculative build by either a declared tag or a whole segment of its entry name. Drop the name half: a tag is now the only signal. A name is author-supplied free text and a naming convention is not a contract, so reading a marker out of one infers a capability nobody declared. The gallery already had the failure in it: the four NVFP4 entries name MTP-bearing weights while setting no option that enables speculative decoding, and being live variants they were winning the feature axis without answering any faster. overrides.options was considered as the replacement and rejected. It carries spec_type:draft-mtp / spec_type:draft-dflash, which is what actually turns the feature on, but that spelling is llama.cpp's config vocabulary: ds4 spells the same feature mtp_path and sglang spells it speculative_algorithm in a referenced config. Keying a cross-backend ranking decision on one backend's option syntax would rank the other backends' builds as plain. Options are the curation-time check instead, and never reach the selection logic. With no fallback left, tag correctness is load bearing, so audit every entry against the rule "tagged when the entry configures that feature, in whatever vocabulary its backend uses". Three entries configure MTP untagged and gain the tag (hy3, glm-5.2, qwythos-9b-claude-mythos-5-1m, all spec_type:draft-mtp with no marker in their names). Four carry the tag while configuring nothing and lose it: qwen3.6-27b-nvfp4-mtp, qwen3.6-35b-a3b-nvfp4-mtp, qwopus3.6-27b-coder-mtp-nvfp4 and qwopus3.6-27b-v2-mtp-nvfp4, whose only option is use_jinja:true. The dflash side was checked independently rather than assumed consistent: all five dflash entries declare spec_type:draft-dflash and all five are tagged, so it needed no edits. Four entries keep a tag that a literal spec_type-only reading would strip, because they configure MTP through a different backend: deepseek-v4-flash-q2-mtp via ds4's mtp_path/mtp_draft, and the three sglang entries via speculative_algorithm in their referenced configs. Stripping those would contradict the reason spec_type was rejected as the signal and would demote four genuinely faster builds to plain. The index was edited by line insertion and deletion only, never round-tripped through a serializer. A resolved-tag diff across all 1272 named entries, taken after merge keys are applied, shows exactly these 7 changing and no entry gaining or losing a tag through an anchor. The two specs that pinned the name fallback are inverted rather than deleted, since a name silently promoting a build is the regression worth guarding. The whole-token guard survives on the tag path, where smtp must still not match mtp.

The parent entry is fine, but all four entries it was grouped with declared neither url: nor config_file:, and applyModel needs one of the two to have anything to build a config from. They carry urls: (plural), the informational HuggingFace link list, which is a different field. None of the four was ever independently installable, so grouping them routed a previously-working install into a broken entry. Give each the url: the parent already resolves through. virtual.yaml is a no-op base, and applyModel passes overrides to InstallModel separately from the fetched config, so backend: ds4, the parameters and the ssd/mtp options all still land exactly as authored. This is the same pattern the parent and many other GGUF entries in the index already use. Add the lint rule that should have caught this. checkVariantReferences only proved a target exists and is not itself a parent, which is structural validity: an entry can exist, declare no variants, and still be uninstallable. checkVariantTargetsInstallable mirrors applyModel's precondition instead, and names the parent, the target and the missing fields, because whoever hits it is reading a gallery entry and has no reason to know applyModel exists. The two index-driven resolution specs live in their own Ordered container: an Ordered container stops at its first failure, so sharing one with the lint rules let a lint breach skip them silently. Nine further entries gallery-wide have the same defect and are unrelated to variants, so they are broken installs that predate this branch. They are left alone here rather than buried in a regression fix, and widening the rule to cover every entry is deferred with them so the gate can ratchet up in one step instead of needing a skip list. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): install entries with no url or config_file on an empty base applyModel had three branches: fetch a base config from url:, build one from an inline config_file:, or fail with "invalid gallery model". An entry declaring neither is now installed on an empty base config, with overrides: and files: supplying everything. This is what the ~345 entries pointing at gallery/virtual.yaml were already getting. That stub is five lines carrying name, description and license. description and license are overwritten from the gallery entry immediately after the fetch, and the name never reaches disk because InstallModel prefers the install name. Crucially applyModel passes model.Overrides to InstallModel as a separate argument rather than merging it into the fetched config, so nothing an author writes depends on that base existing. The fetch bought a round trip to GitHub and nothing else. That makes f4ef80173 the wrong fix, so it is unwound. The four url: lines it added to the deepseek-v4-flash variants are reverted: they are a pointless network fetch now, and the family installs without them. Relaxing the branch would hide a real authoring mistake, so a payload rule replaces the base-config rule. An entry with no url, no config_file, no overrides and no files installs nothing and would leave an empty model directory while reporting success, so it is refused by name. The caller's request counts toward the payload, because its overrides and files are merged into the install exactly as the entry's own are. urls: (plural) is the informational link list and does not count, which is what the four entries that shipped broken had and why they were still uninstallable. checkVariantTargetsInstallable asserted every variant target declares a url: or a config_file:, which is no longer true and would now reject correct authoring. checkEntriesInstallSomething pins what survives instead, and covers every entry rather than only variant targets: the hazard is a half-written stanza and a parent can be one as easily as a target. The old rule was scoped to targets precisely because nine unrelated entries would have failed a gallery-wide version; those nine are valid now, so the deferred ratchet happens here in one step. 1280 entries, zero violations. Those nine (aurore-reveil_koto-small-7b-it, lfm2-1.2b, the six liquidai_lfm2 entries and deepseek-v4-pro-q2-ssd) become installable for free. Each carries overrides: and files:, and one of them is driven through the real install path in a spec. The no-fetch spec is paired rather than bare: an assertion that nothing was fetched proves nothing unless something could have been, so a control runs the same fixture with a url: pointing at a base config that is not there and asserts the install fails. Only then does the identical fixture without the url passing mean the read was skipped. Follow-up, deliberately not here: the ~345 entries still naming virtual.yaml can drop their url:. That is 345 index edits with their own risk, and mixing them in would bury this change. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * ui(models): let search bypass the variant collapse, drop the toggle The models page collapsed the gallery to one row per model by default and offered a toggle to see every individual build. Because the collapse composed with the search term, a build another entry offers as a variant could not be found by typing its name, so the toggle was the only way to reach those builds in the UI. A user who typed a name they knew existed got "no models found", which reads as "that model does not exist". Collapse is for browsing; search is for finding. An explicit search term now bypasses the collapse in the listing handler, so a name lookup returns matching entries whether or not a parent offers them. The term is trimmed once at the top of the handler, so whitespace is neither a search nor a bypass; previously an untrimmed blank term also narrowed the listing to whatever contained a space. Tag and backend deliberately do not bypass: they refine a listing the user is still reading rather than name an entry already known to exist. That makes the toggle redundant, so it goes, along with its i18n strings in all six locales, its localStorage persistence, its participation in "Clear filters" and the empty-state hint telling users to turn it off. The hint was doubly stale: it pointed at a control that no longer exists, and it was untrue exactly when a user has a search term, since searching now sees every build. The page always requests the collapsed listing. The stored preference key is left inert rather than cleaned up: nothing reads it, so a user who had the toggle off simply gets the collapsed view. collapse_variants stays on the API, off by default, because other clients want either view and the UI dropping its control is no reason to remove a working parameter. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): give the models gallery filter form a deliberate structure The filter area had accreted controls into one undifferentiated flow. The "Fits in GPU" toggle and the backend select were direct children of .filter-bar, the same wrapping container as the 18 taxonomy chips, so their position was decided by how many chips happened to wrap at the current width rather than by any layout intent. At narrow widths they were pushed past the right edge of that container's horizontal scroll and became unreachable entirely. Restructure into three bands inside the house .filter-bar-group wrapper that components/FilterBar.jsx already uses on Backends and the System tabs: 1. query scope: search plus the backend select 2. taxonomy: the chip row, alone, free to wrap 3. refinements: fits-in-GPU and context size, under a hairline rule The backend select leads the chips rather than trailing them because picking a backend disables the use cases that backend cannot serve, so it gates the row below it. Fits-in-GPU and context size share a band because they are one control group: the context size is the length the VRAM estimate is computed at, and that estimate is what the fits filter tests against. Chips had no visible keyboard focus indicator. The global focus ring is wrapped in :where(), so it carries the specificity of a bare :focus-visible, ties with .filter-btn and loses on source order, leaving focused chips showing their resting drop shadow. Restate the ring where it outranks both resting and hover. Also: aria-pressed on the chips, a real label association and aria-valuetext on the context slider (it steps over an index, so it announced "2"), disabled chip styling moved off inline styles, a prefers-reduced-motion block for the chip transition, and the hard-coded English "Context:" moved into all seven locales. No behaviour change: same filters, same state, same requests. Page reset on change, localStorage persistence and "Clear filters" verified unchanged. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): let the models recommendations panel fade into the background The "Recommended for your hardware" strip rendered at full height on every visit regardless of how many models were already installed, costing 186px at 1600px wide (287px at 1100px, where its cards wrapped to two rows) and pushing the first gallery row to y=554 / y=703. Make its prominence track how much the user still needs it. The panel now defaults to a one-line summary once anything is installed, and both the collapse choice and the existing dismissal persist: collapsed = explicit user choice, if one exists : installedCount > 0 The preference is three-valued on purpose. A boolean cannot tell "the user expanded it" apart from "the user has never chosen", and those need opposite handling when the installed count later crosses zero: someone who deliberately opened the panel on an empty instance should not have it collapse out from under them when their first model finishes installing. Collapsed keeps the card, icon, title and a suggestion count, so the panel is recovered by clicking what you are already looking at rather than by hunting. Expanded is unchanged, because for a user with nothing installed it was never the problem. Collapsed reclaims 145px at 1600 and 420, and 246px at 1100. Models.jsx gains a statsLoaded flag: stats initializes to installed:0, so reading it before the fetch resolves would render expanded and collapse a frame later, which is exactly the layout shove this removes. The dismissal key moves to the page's localai-models-* convention; the old localai_rec_models_dismissed is still read, never written, so an existing dismissal is honoured rather than resurrected by the rename. Accessibility: the disclosure is a real button whose accessible name is the visible title alone, with state on aria-expanded and aria-controls resolving in both states, because the grid is hidden via the hidden attribute rather than unmounted. That also keeps the four install buttons out of the tab order while collapsed. The app's global focus ring applies; no per-component outline is added, per the warning in App.css. Reveal animates opacity and transform only, never height, and both it and the chevron rotation are disabled under prefers-reduced-motion. Only en had a recommended block, so the other six locales were falling back to English for the whole panel. Translated the complete block rather than adding one orphaned key to files that would still render the title in English. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(downloader): recover from a leftover .partial on non-HTTP URIs An interrupted download leaves a `<file>.partial` behind. The partial handling in DownloadFileWithContext gated resume on `err == nil && uri.LooksLikeHTTPURL()`, so for any URI that is not literally http(s) the branch fell through to `else if !errors.Is(err, os.ErrNotExist)`, which with a nil err is true. The download then failed with an error wrapping nil: failed to check file ".../Ternary-Bonsai-27B-Q2_g64.gguf" existence: <nil> Every gallery file URI uses `huggingface://`, so a single interrupted download made that model permanently uninstallable until someone deleted the partial by hand. The `<nil>` in the message compounded it by pointing debugging at a filesystem failure that never happened. Restructure the handling as an explicit switch over the four real states: partial exists and is resumable, partial exists and is not resumable (discard and restart, as already done for an HTTP server without range support), no partial, and a genuine stat failure. The error branch is now only reachable with a non-nil error, names the path that was actually stat'd, and wraps with %w. Discarding is required for correctness and not merely convenience: the writer opens the partial with O_APPEND, so an un-resumed download would concatenate a fresh body onto stale bytes.

For two builds of one model that is close to no information: a variant exists precisely because the same weights are offered another way, so the backend usually matches and the sizes usually land within a few hundred megabytes. Comparing ternary-bonsai-27b-pq2 against ternary-bonsai-27b-q2-g64 meant reading two names that differ by a suffix nobody has defined anywhere in the UI. Report the quantization and the serving features on VariantView, and derive both server-side from the referenced entry rather than parsing names in the browser, so every client reads the same format out of the same file the installer will hand the backend. Quantization comes from overrides.parameters.model first, falling back to the file list. That order is load bearing: entries routinely ship a vision tower alongside the language model at a different quantization, so reading the file list first reports the mmproj's format. Matching walks `-` and `.` delimited segments right to left; `_` deliberately does not split, because it separates the parts INSIDE a quant token and splitting on it reports Q4 for a Q4_K_M build. A second, looser pass takes a segment's `_`-delimited tail, which catches the gemma-4-E2B_q4_0-it.gguf style; it runs second so a precise match can never lose to a fuzzy one further right in the name. An entry naming no format reports nothing, which is the honest answer for a backend served from a directory of weights. Features are the same tag-against-vocabulary match servingFeatureRank already ranks on, over the same host preference list. A build can therefore never be shown as faster than one selection did not actually reward, nor rewarded without being shown; a spec pins that agreement rather than trusting it. The compact dropdown gets the quantization on its meta line and the bare feature token. The detail row, which has the room, gets the quantization as its own monospaced column so precision lines up down the list, and the feature spelled out, because DFLASH names nothing to a user who has not met it. The referenced entry's description stays out of both: the detail row already renders the parent's prose above the table, and a second block per variant would push a three-variant list past a screen to restate what the columns now say precisely. The collapse toggle comes back. 462583f38 dropped it once search bypassed the collapse, on the reasoning that nothing was unreachable any more. That holds for finding a build whose name you know and does not hold for browsing: no sequence of actions enumerated the 68 builds the default view hides. Collapse is for browsing and search is for finding, and the toggle was the browsing half. It goes in the refinements band 0d4823362 established, not back among the taxonomy chips where its position depended on how many chips happened to wrap. It leads that band because it decides how many rows the other two refine over, and because unlike fits-in-GPU it is unconditional: a host with no GPU still browses. The search bypass is untouched and re-checked by a spec in the toggle's default state, since restoring the control must not restore the dead end it replaced. The empty-state hint returns but only without a search term, because a term bypasses the collapse and the hint would otherwise point at a control that cannot change the result. The stored preference reads 'on'/'off' only: an older build wrote '1'/'0' from an effect that ran on mount, so those record that the page was opened, not that anyone chose a view. Also fixes a latent flake it exposed. The collapse_variants spec compared whole response bodies byte for byte, and the listing envelope carries live host telemetry that drifts between two calls milliseconds apart, so it was asserting on the machine's memory pressure. It now compares everything the parameter governs -- the entries, their serialization and the paging -- and is green 25/25 where it was failing about one run in three. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): let the models gallery show a variant's full details The variant list in an entry's expanded detail row says how the builds differ: name, backend, quantization, size, and the auto-selected, base and serving-feature markers. It cannot say what any one of them is. A variant's own description, tags, license, source links and file list are unreachable anywhere in the UI, because while the collapse is on a variant has no gallery row of its own. Give each variant row an info control that reveals its entry, rendered by the same ModelDetail a top-level row gets, so a field added to the detail view appears here too. variantData is withheld from the nested render: a variant may declare variants of its own, and recursing would nest a picker inside a picker two levels deep already. An inline disclosure rather than a modal. The control sits inside a table row that is already expanded, inside a variant list within that; a dialog opened from there stacks a dismissal on a dismissal for a handful of extra fields about the entry the user is already reading, and breaks the page's own expand idiom. The third level is carried by an inset and a left rule instead of another card. The entry is fetched by exact name from the listing, once, on first use. The listing already returns every field the detail view renders, and a search term bypasses the variant collapse server-side, so no new endpoint is needed and neither the listing nor DescribeVariants gains any work. Expanding a row costs nothing; a variant nobody opens costs nothing. A name the listing no longer returns is stated, not blanked: an empty panel reads as a rendering fault rather than as a lookup that came back empty. The control is a sibling of the install button, not a descendant, so asking about a build can never install it. The variant list keeps its content-sized columns via a trailing filler track instead of max-content sizing, so the rows are unchanged while the panel spanning them gets the pane width its file table needs. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): let search respect the collapse instead of switching it off The models listing collapsed to one row per model, and an explicit search term turned that off wholesale. Searching while collapsed therefore answered with the individual builds a parent already offers, which are exactly the rows the view the user asked for has no place for: typing "mtp" returned qwen3.6-27b-nvfp4-mtp, a row that is invisible the moment the box is cleared. The bypass was the right shape of fix for the wrong half of the problem. What a search must not do is answer "no models found" for a build the gallery does hold; that does not require abandoning the grouping the user asked for. So the term is now matched against every entry either way, hidden builds included, and the collapse decides how a match is reported rather than which matches exist. Collapsing stops being a filter that drops rows and becomes a substitution: a match on a build another entry offers is reported as that entry, the one installable in its own right. Nothing becomes unfindable and nothing comes back that the requested view cannot show. Substitution happens after search, tag and backend, so every filter is judged against the build that really carries the name, tag or backend rather than against a parent that merely offers it; the other order would let backend=vllm match a parent whose own backend is something else. The price is that the surfaced row shows the parent's own metadata while the match was on a variant, which is what grouping means, and the alternative is claiming the gallery holds no such build. It happens before the count and the page math, so both describe the rows actually handed out rather than the matches that produced them. A parent already in the result keeps its own position and absorbs its matching variants there, which is what leaves the browsing listing ordered exactly as it was; a parent surfaced only by a variant takes the position of the first variant that surfaced it. Either way it appears once, however many of its builds matched and whether or not it matched itself. Search preserves gallery order rather than scoring, so a surfaced parent has a real position rather than an invented one. VariantParents never reports an entry that declares variants of its own, so a parent is never itself hidden and one hop always lands on a visible row. The handler follows exactly one anyway: refusing the second is what makes a gallery the linter would have rejected terminate rather than loop. The empty-state hint pointing at the toggle goes with it for every server-side filter. Substitution means a match is always reported as some row, so the collapse can no longer be why a term, a chip or a backend came back empty, and naming it there sends the user to a control that cannot change the result. It survives for the fits filter alone, which runs in the browser after the substitution and judges the surfaced entry's own size: there the build that fits really can be filtered out along with a parent that does not. Searching a build's exact name while collapsed now answers with its parent, so the result no longer contains the string the user typed. That is intended, and the row is the one they can act on, but it is a real rough edge: nothing on the row explains the connection. Closing it properly means reporting which variant matched so the UI can say so, which the listing does not do today. ResetGalleryModelCache is added for tests. The model cache is a package global keyed by nothing, so a background refresh one spec triggers can land in the middle of the next and answer it with the previous spec's gallery; the extra specs here made that fail about one run in five. It waits for the in-flight refresh to publish before clearing, since clearing alone only narrows the window.

mudler's LocalAI [bot]	9d82c37f98	fix(distributed): backend discovery hid worker-installed backends behind the controller's filesystem (#10967) ... fix(distributed): backend discovery hid worker-installed backends Backend discovery endpoints filter on installed-state, which on a distributed controller derives from the controller's own filesystem. A backend lives on the worker node that runs it, so every backend an admin installed on a GPU worker read as "not installed" and vanished from the listing. #10947 fixed the sibling capability filter on the same endpoints, so a fine-tuning-capable GPU worker now made the backend listable while the installed-state filter still dropped it: the dropdown stayed empty. The controller cannot derive this locally, but it already aggregates the per-node view that GET /backends renders, so discovery reuses the active BackendManager rather than growing a second path. Three surfaces shared the root cause and route through the same helper now: - GET /backends/available (Installed is now cluster-wide) - GET /api/fine-tuning/backends - GET /api/quantization/backends The response stays a boolean rather than an installed-on-N-of-M count: per-node install state is already served by GET /backends nodes[], and per-node control by POST /api/nodes/:id/backends/install, so a summary is all these dropdowns need. A nil provider (single-node) leaves the local filesystem as the only source and reproduces today's listing exactly, and a registry error degrades to that same listing instead of blanking the catalog.

mudler's LocalAI [bot]	f735cb24c0	fix(worker): reap deleted backends and stop models that live on a worker (#10956) ... * fix(worker): reap deleted backends and stop models that live on a worker Three related backend-lifecycle defects, all reachable from the same production incident on a Jetson/Thor worker: a deleted backend's gRPC process survived ~40 minutes with its directory removed from disk, a later model load was routed to that orphan and failed with a certifi path pointing into the deleted directory, and the admin could not stop the model because the frontend reported it as not loaded. 1. backend.delete orphaned the process it claimed to delete ------------------------------------------------------------ s.processes is keyed by `modelID#replicaIndex` (buildProcessKey), so the backend name never appeared in a key and was recorded nowhere on the process. backend.delete resolved its target via isRunning/stopBackend, whose prefix path only matches a bare *modelID* - a delete keyed on a backend name resolved to zero keys, the stop silently no-op'd, and the files were removed out from under a live process. The install fast path then handed that orphan back out: it returns any live process for the (model, replica) slot without checking which backend started it, so a reinstalled variant inherited the deleted backend's port. - Record backendName on backendProcess, threaded installBackend -> startBackend. - Add resolveProcessKeysForBackend, matching the recorded name and resolving alias <-> concrete via ListSystemBackends *before* DeleteBackendFromSystem erases the metadata that carries the alias. Alias resolution failure degrades to name-only matching so a delete never fails on it. - backend.stop goes through resolveStopTargets, which accepts a backend name, a model name, or an exact modelID#replica key. Its payload field is named "backend" but is published with all three meanings: the admin UI sends a backend name, UnloadRemoteModel sends a model name, and the router's abandoned-load reap (#10948) sends an exact replica key. Narrowing it to backend names alone would strand the latter two. backend.delete stays strict - its identifier is unambiguously a backend. - Gate the install fast path on processMatchesBackend so a slot held by a different backend is restarted rather than reused. Processes with no recorded name (pre-upgrade) are accepted, so rollout does not restart every running backend. - stopBackendExact reports a real stop failure - the process still being alive afterwards, which is precisely what finishBackendStop already detects to keep the entry and its port reserved - and backend.delete no longer replies success when it knew about a process and could not kill it. "No process was running" stays a success but is logged, so the orphan case is visible rather than silent. 2. /backend/shutdown reported a running model as missing --------------------------------------------------------- ModelLoader.deleteProcess short-circuits on a miss in this replica's in-memory store. In distributed mode the authoritative record of "is this model loaded" is the shared node registry: a frontend replica that never served the model itself (load balancer picked a peer, or the replica restarted) has no local entry. The remote unload path that pkg/model documents ("when ShutdownModel is called for a model with no local process, UnloadRemoteModel is called") sat behind that short-circuit, unreachable in exactly the case it exists for. #10865 reworked this function but kept the short-circuit at the top, so the gap survived that refactor. - deleteProcess consults the remote unloader on a local-store miss, via a shared unloadRemote helper so this branch and the existing no-local-process branch both prefer #10865's RemoteModelContextUnloader, preserving force propagation across the distributed boundary. - UnloadRemoteModelContext reports ErrRemoteModelNotLoaded when no node has the model; it previously returned nil, making a no-op stop indistinguishable from a real one. The converse case (nodes have it, none could be stopped) already errors since #10865 joined the per-node failures, so that half of the original fix was dropped as redundant. - Only when the model is absent locally AND cluster-wide does the endpoint report not-found, now 404 naming both scopes rather than a bare 500. - modelNotFoundErr becomes the exported ErrModelNotFound so the HTTP layer can map it without string matching; watchdog's identity comparison becomes errors.Is. 3. Coverage for the bounded Free() that #10865 shipped untested ---------------------------------------------------------------- The original branch also bounded the pre-stop Free(), but #10865 landed that fix first (workerBackendFreeTimeout, applied in both stopBackendExact and handleModelUnload). That production change is therefore DROPPED here as superseded - master's version is strictly better, since it also releases the supervisor mutex across the call and keeps the port reserved until termination completes. What #10865 did not ship is a test, and the bound is load-bearing: the router-side reap in #10948 sends backend.stop for an abandoned load, and against a wedged backend an unbounded Free would swallow that stop before it reached the process. Nothing failed if the bound regressed. The spec stands up a real gRPC backend server whose Free handler never returns - what a Python backend looks like when its single worker thread (PYTHON_GRPC_MAX_WORKERS=1 on 37 backends) is occupied by a stuck LoadModel. A stub socket is not sufficient and was tried first: without a completed HTTP/2 handshake, gRPC's own ~20s connect timeout ends the call, so that version passed against the very bug it targets. With the connection READY, only the caller's deadline can end it, so the spec hangs to its 60s limit if the timeout is removed and passes with it. Its fixture process is deliberately never started. go-processmanager v0.1.1 writes Process.pid from readPID() without synchronization, so a live process races its own monitor goroutine under -race - reproducible with a bare Run()+Stop() and unrelated to this spec. Since scripts/model-lifecycle-conformance.sh runs this package with -race and is fail-closed, starting one would turn that gate red on an upstream defect. An unstarted process still proves the point: the stop is reached and the slot released, which is exactly what an unbounded Free prevents. Verified: make lint (new-from-merge-base origin/master) reports 0 issues; scripts/model-lifecycle-conformance.sh passes all three stages including the FizzBee liveness check (1458 states, IsLive: true).

That narrowed a shared adapter contract to serve one caller and broke the documented idempotent-unload guarantee, which CI caught on PR #10956: [FAIL] Node Backend Lifecycle (NATS-driven) > NATS backend.stop events should be no-op for models not on any node [Distributed] Expected success, but got: model not loaded on any node The spec name states the contract outright. The matching unit assertion was updated in that commit; this e2e one was missed because it lives under tests/e2e/ with no build tags and does not run in package-scoped test runs. Caller audit - who breaks when an idempotent unload becomes an error: - pkg/model/watchdog.go:902 (LRU memory reclaimer) is the serious one. It untracks a model ONLY when shutdown returns nil or ErrModelNotFound. A new error type means the model is never untracked, so the reclaimer keeps re-selecting the same entry and never reclaims - a live wedge whenever a local store entry outlives the remote model. - core/services/galleryop/managers_local.go:43 (DeleteModel) would warn on every deletion of an already-unloaded model. - core/services/modeladmin/{state,config,remote_sync}.go stop instances best-effort against models that are frequently not loaded. - deleteProcess itself: the no-local-process branch returns the unload result directly, so a stale local entry for a model no longer on any node turned a previously-successful cleanup into a failure. Only ShutdownModel wants the distinction, and only on the local-store-miss path. So the distinction moves to the caller instead of the contract: - UnloadRemoteModel/UnloadRemoteModelContext return nil again when no node has the model, and ErrRemoteModelNotLoaded is removed. - New optional RemoteModelPresenceChecker (HasRemoteModel) answers the question directly. deleteProcess consults it BEFORE unloading, because an idempotent unload cannot report afterwards whether anything was stopped. Absent locally AND cluster-wide is the only case that reports 404. - A failed registry lookup is surfaced rather than reported as absence: an unreachable registry is not evidence a model is gone, and answering a confident 404 off a failed lookup is how an operator gets told a running model does not exist. - Unloaders that predate the extension keep working - deleteProcess attempts the unload rather than refusing it - and compile-time assertions in the nodes package now pin all three optional interfaces, since both are consumed by runtime type assertion where drift degrades behavior silently instead of failing the build. The contract is now pinned at both levels that disagreed, each spec pointing at the other: "with no nodes returns nil" in unloader_test.go and "should be no-op for models not on any node" in node_lifecycle_test.go. Verified: full distributed e2e suite 233 passed / 0 failed (the suite that failed 232/1 in CI); pkg/model and core/services/nodes green; make lint new-from-merge-base reports 0 issues. Assisted-by: Claude:claude-opus-4-8 golangci-lint Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed): drop replica rows when a worker stops a backend A worker returns a stopped backend's gRPC port to its allocator as soon as the process is confirmed dead, and hands it to the next backend that starts. The controller's NodeModel row for the old address survives, and both SmartRouter.probeHealth and the HealthMonitor per-model probe verify liveness, not identity, so once an unrelated backend binds the recycled port the stale row passes every check and the request is served by the wrong backend instead of failing. backend.delete is newly able to trigger this: before #10956 a delete never actually stopped a process, so it never recycled a port. backend.upgrade has the identical gap and always did — upgradeBackend force-stops every process using the binary and starts none back up, while DistributedBackendManager.UpgradeBackend never removes rows. model.unload is the one path that gets this right today: it calls RemoveAllNodeModelReplicas straight after StopBackend. Report the process keys the worker terminated on the delete and upgrade replies, and drop the matching rows in RemoteUnloaderAdapter, which already holds a ModelLocator with RemoveNodeModel. All three call sites funnel through that adapter, so no new interface, DB migration, or proto change is needed. A key is reported only once its process is confirmed gone, so the list stays trustworthy on the partial-failure replies too. Old workers never populate the new fields. ReportsStoppedProcesses tells "stopped nothing" apart from "does not report", so an old worker's silence falls back to the pre-existing probe-based staleness recovery instead of being mistaken for a completed cleanup. Quarantine released ports for a short window as an interlock covering the NATS round-trip between the worker freeing the port and the controller dropping the row. It is deliberately not derived from HealthCheckInterval: that cadence is operator-tunable and the per-model reaper can be disabled outright, so coupling a worker-local constant to it would be silently wrong on some clusters. Eager row removal is the fix; the delay only closes the handoff gap. Identity verification in probeHealth was considered and rejected: Health and Status carry no backend identity, so it needs a proto change plus an implementation in 36 Python and 4 C++ Health servicers, it is fail-open for any backend not yet rebuilt, and the probeCache short-circuit means it would not even execute during the 30s window where the misroute happens.

LocalAI hit this on every backend stop. Upstream fixed it in a94e2b7 by guarding PID with a mutex and adding CurrentPID() as a race-safe accessor. The exported field was kept to avoid a breaking change but is now deprecated: a direct read still races the monitor. No tag carries the fix yet, so pin the pseudo-version. GetGRPCPID reads through CurrentPID() instead of the field. The accessor returns the same string under an RLock, so the empty-PID and strconv error paths are unchanged; it is the only direct field read in the tree. With the race gone, the Free-timeout spec no longer has to leave its fixture process unstarted. It now runs a real child and asserts the child genuinely exits, which is exactly what the earlier workaround gave up: the spec could show the stop was reached and the slot released, but not that SIGTERM ever landed. Termination is observed through Done(), which closes only once the library has waited on the child. The pidfile-based liveness helpers cannot serve here, because Stop() deletes the pidfile while releasing the handle and so reports "not alive" even if no signal was sent.

Tai An	dc2cc4da43	fix(audio-transform): serialize WebSocket writes to avoid concurrent-write panic (#10857) ... * fix(audio-transform): serialize WebSocket writes to avoid concurrent-write panic AudioTransformStreamEndpoint writes to the same Gorilla WebSocket connection from two goroutines: the backend-forwarding goroutine emits binary PCM frames (and can call sendWSError on a backend recv error), while the read loop calls sendWSError for malformed mid-stream JSON or a backend send failure. Gorilla WebSocket permits only one concurrent writer, so these writers race and can panic with "concurrent write to websocket connection", resetting the client session; a -race build reports the data race directly. Wrap the connection in a lockedConn that serializes WriteMessage behind a mutex, mirroring the existing lockedConn used by the openresponses WebSocket endpoint. Reads stay on the single read loop, so only writes need the lock.

When another service already listens on 9090 the suite does not fail fast: the server goroutine logs the bind error and the specs then poll whatever is squatting the port until Eventually times out.

That fires NATS backend.install with force=false, and the worker's install handler is deliberately "ensure installed": when the backend binary already exists on disk it short-circuits without touching the gallery. Since only an installed backend can be upgraded, the whole chain was a guaranteed successful no-op - the UI then toasted "backend upgraded" without even waiting for the async job. Route upgrades through the real force-reinstall path instead: - BackendManager.UpgradeBackend now receives the ManagementOp (like InstallBackend already did) so implementations can honor op.TargetNodeID. - DistributedBackendManager.UpgradeBackend scopes the backend.upgrade fan-out to op.TargetNodeID when set, and errors when the target node does not report the backend as installed. - New POST /api/nodes/:id/backends/upgrade endpoint enqueues an Upgrade=true node-scoped op (async 202 + jobID, mirroring install). - NodeDetail UI calls the new endpoint and reports the dispatch ("Upgrading ... on this node...") instead of claiming success; the Operations panel tracks the actual job. Verified against a live local cluster (NATS + Postgres + two workers): the target worker stops the running process, force-reinstalls from the gallery and re-downloads the OCI image; the second worker receives no backend.upgrade event; upgrading a backend missing from the target node fails the job with a clear error.

As a result the model config's parameters.language / parameters.translate (a valid PredictionOptions field under `parameters:`) were silently ignored, and multilingual models like canary defaulted to translating into English even when the YAML set language: ru, translate: false (#10655). Resolve both with clear precedence: the request form field wins, then any language on the parsed request, then the model config default. This also makes the endpoint honor OpenAI's `language` form parameter, which was not read before. Applies to both the streaming and non-streaming paths (the resolved values are built into the shared TranscriptionRequest).

LocalAI [bot]	b0959d4756	feat(api): add GET /v1/models/capabilities endpoint (#10687) ... Additive superset of /v1/models that enriches each model entry with the capabilities it supports plus its input/output modalities (text / image / audio / video). Clients that only understand /v1/models are unaffected -- they simply never call the new route. Audio and video *input* are derived from the model's multimodal limits (vLLM limit_mm_per_prompt), which no single usecase FLAG expresses. That gap is exactly why a plain capability list is insufficient and this enriched endpoint exists: an attachment router can now decide whether an image/audio/video file can go to the active model directly, or must be converted/transcribed first. Capability derivation lives in core/config as the single source of truth (ModelConfig.Capabilities / InputModalities / OutputModalities / VisionSupported / ...); the Ollama capability surface now delegates to it instead of keeping a parallel copy. Vision is gated on chat/completion capability so a MediaMarker hydrated onto a non-chat model (e.g. a pure ASR/TTS backend) no longer reports a false vision capability. Read-only listing: no new FLAG_* flag, reuses the existing `models` swagger tag, and intentionally exposes no MCP admin tool (there is nothing to manage conversationally).

Richard Palethorpe	eb32cd9073	feat(realtime): eager blocking pipeline warm-up + /backend/load API (#10662) ... Realtime sessions previously lazy-loaded each pipeline sub-model (VAD, transcription, LLM, TTS) on first use, so every cold session paid a per-request model-load stall and load errors only surfaced mid-stream. Warm the whole pipeline eagerly and blockingly at session start (including the voice-gate speaker-recognition model, which an enforced gate blocks each utterance on; compaction's summary_model stays lazy since it only runs off the response path): - Add backend.PreloadModel / PreloadModelByName as the single load path for every modality (no transcription special-case; backend-omitted configs are deprecated). - The realtime session blocks on Model.Warmup and returns a model_load_error to the client if any stage fails to load; updateSession warms in the background. Opt out per pipeline with pipeline.disable_warmup, exposed as a UI toggle via the config-metadata registry. Add a LocalAI-native POST /backend/load (and /v1/backend/load) that pre-loads a model -- expanding realtime pipelines into their sub-models -- as the inverse of /backend/shutdown. There is one preload engine (backend.PreloadStages): the realtime Warmup methods, /backend/load and the --load-to-memory startup flag all use it, so --load-to-memory now also expands pipeline models and records load-failure traces. Pipeline sub-model alias resolution is likewise shared (ModelConfigLoader.LoadResolvedModelConfig). Surface the endpoint everywhere an admin manages models: - MCP admin tool load_model (httpapi + inproc clients, safety/catalog prompts, catalog/dispatch tests). - "Load into memory" action in the React models UI. - Swagger regenerated; docs moved to the general backend-monitor page since it is not realtime-specific. Fix a Traces UI crash ("json: unsupported value: -Inf"): audio-snippet RMS/peak now floor at a finite dBFS, and backend-trace data is sanitized to drop non-finite floats before marshaling. The sanitizer is copy-on-write -- it runs on every RecordBackendTrace, so containers are only re-allocated on the paths that actually changed. Migrate core/http/openresponses_test.go onto the prebuilt mock-backend the rest of the http suite already uses -- it was the last spec still pointing at a real HuggingFace model, so it 404'd wherever no vision backend was built -- and fix its item_reference specs to send the spec's "id" field instead of "item_id", which the handler never accepted.

API clients that ensure a backend exists at startup paid a full OCI image pull on every boot. Backend install ops now default to non-forced — an installed, runnable backend short-circuits (the orphaned-meta reinstall path in InstallBackendFromGallery is preserved) — and reinstall stays available: - ManagementOp gains a Force field; the local manager passes it through instead of hardcoding true. - /backends/apply accepts an optional "force" boolean in the body. - The React UI install route keeps forcing, since its button doubles as the explicit "Reinstall backend" action.

Richard Palethorpe	5d0c43ec6e	feat(realtime): Semantic VAD EOU token (#10444) ... * feat(realtime): EOU-driven semantic_vad turn detection Add a `semantic_vad` turn-detection mode to the realtime API that feeds the transcription model live and decides "the user finished speaking" from the `<EOU>` end-of-utterance token rather than from silence alone. When EOU fires the turn commits immediately (~0.3s); otherwise it falls back to an eagerness-scaled silence threshold (low/med/high = 8/4/2s). Plumbing, bottom to top: - proto: `AudioTranscriptionLive` bidirectional RPC (config-first oneof, mono float PCM @16k, ready-ack / Unimplemented degrade signal) plus `TranscriptResult.eou` for the unary retranscribe gate. - pkg/grpc: client/server/base/embed scaffolding for the bidi stream, modeled on AudioTransformStream; release stream conns on terminal Recv. - parakeet-cpp: live transcription RPC with per-C-call engine locking (one live stream per turn, finalize+free at commit); bump parakeet.cpp to ABI v5 — incremental StreamingMel (no more quadratic per-feed mel recompute that delayed EOU on long turns) and the <EOU>/<EOB> split; strip the literal <EOU>/<EOB> from offline text and set Eou. - core/backend: LiveTranscriptionSession wrapper + pipeline `turn_detection:` config block (type/eagerness/retranscribe). - realtime: semantic_vad integration — live input captions streamed as transcription deltas while the user speaks, EOU-immediate commit with eagerness fallback, optional retranscribe gate (batch re-decode must also end in <EOU> to confirm), clause synthesis off the LLM token callback, and per-turn live-transcription / model_load telemetry. - UI: show the realtime pipeline components as a vertical list.

Make them explicit and keep the implementation in step with a formal design; rework the parakeet streaming backend along the same lines. Realtime state machines (M1-M5). Each is a sealed sum-type State/Event/Effect with a total, pure Next(state,event)->(state,[]effect) behind a single-writer Coordinator: M1 conncoord connection lifecycle: VAD toggle + once-only teardown (replaces vadServerStarted + a `done` channel closed from two sites). M2 turncoord turn detection: collapses speechStarted and the live-stream "turn open" flag into one state, so discardTurn can no longer desync them and suppress the next onset. M3 respcoord response coordination: serializes the dual-writer start/cancel so at most one response is live; one response.done per response.create. M4 compactcoord conversation compaction: single-flight (replaces the `compacting atomic.Bool` CAS). M5 ttscoord TTS pipeline: open->closing->closed, idempotent wait(), rejects enqueue-after-close (was a silent drop). The Coordinator/Sink/Next plumbing — only the sealed types and Next differed per machine — is extracted once into core/http/endpoints/openai/coordinator as a generic Coordinator[S,E,F]; each machine keeps its public API via type aliases, so no sink, call-site, or test moved. Hierarchy. session_lifecycle.fizz models M1 as the parent region with its children (M2/M3/M4) as one statechart and asserts ChildrenDieWithParent (conn torn => all children terminal, none start after teardown). respcoord and compactcoord gain an absorbing Terminated state + Shutdown event; conncoord's teardown drives the children terminal. This closes a compaction teardown gap: a fire-and-forget compaction could outlive a torn session — compactionSink now takes a session-scoped cancellable context + WaitGroup and joins the in-flight summarize+evict on shutdown. Formal verification. formal-verification/ holds one authoritative FizzBee spec per machine plus the composition spec, each with an always-assertion and a documented one-line edit that makes the checker fail (verified non-vacuous). scripts/realtime-conformance.sh is fail-closed: all Go conformance suites under -race AND a model-check of every .fizz spec; a missing FizzBee is a hard error (only the loud REALTIME_CONFORMANCE_SKIP_FIZZBEE=1 bypasses it, never in CI). FizzBee is pinned by sha256 and installed via scripts/install-fizzbee.sh into .tools/ (gitignored). Wired as make test-realtime-conformance, a CI workflow, and a pre-commit path filter. Go conformance tests are Ginkgo/Gomega (per the repo's forbidigo lint): transition tables + fixed-seed property walks + concurrent/-race specs, no rapid dependency. Design map: docs/design/realtime-state-machines.md. Parakeet streaming backend. The same treatment applied to the parakeet-cpp streaming paths: - AudioTranscriptionStream returns codes.Unimplemented for non-streaming models instead of decoding offline and emitting it as one delta + final. A client that asked for streaming learns the model cannot stream rather than receiving a batch result shaped like a stream. New grpcerrors.StreamTranscriptionUnsupported carries that signal; the HTTP /v1/audio/transcriptions stream path surfaces it as an SSE error event. Mirrors AudioTranscriptionLive, which already did this. - utteranceBoundary (boundary.go): a single definition of the end-of-utterance latch, replacing three open-coded finalEou toggles. Modelled as a two-valued type so illegal states are unrepresentable. - Shared decode driver (driver.go): streamFeedResult (one per-feed event) + feedChunk (hides the ABI v4 JSON vs text-only split) + feedSlices + flushTail. The feed loop is written once. - AudioTranscriptionLive becomes a bidi adapter: it streams the per-feed {delta,eou,eob,words} the realtime turn detector consumes and a terminal FinalResult carrying only Text. Segments/duration/eou are offline-only and no longer produced (nor read) on the live path; liveTraceState drops the terminal eou and keeps the per-feed eou_events count. - AudioTranscriptionStream + streamJSON merge into one driver-based function; streamSegmenter is generalized to the unified event with a text-only fallback that preserves the legacy (no-words) library's per-utterance segmentation. Verified: build/vet/gofumpt clean, golangci-lint 0 issues, all coordinator and parakeet packages under -race, the fail-closed conformance gate green, and make test-realtime (12 e2e WS+WebRTC).

LocalAI [bot]	ade9cc9e37	fix(openresponses): bound resume-stream buffer and enforce response ownership (#10569) ... The background=true resumable-stream path had two latent issues. 1. Unbounded resume buffer. AppendEvent grew StreamEvents without limit, so a long-running or abandoned background generation could consume process memory without bound. The store now caps the buffer (event count and total bytes, mirroring llama.cpp's byte-capped slot ring), evicting oldest events from the front and advancing a droppedThrough watermark. GetEventsAfter returns ErrOffsetLost when the requested starting_after is below the watermark, and handleStreamResume surfaces that as HTTP 409 before committing to the SSE response, so a resuming client gets a clear error instead of a silently truncated stream. 2. Missing ownership check (IDOR). GET /responses/:id, its stream resume, and /cancel looked up responses purely by ID, letting any caller who knows or guesses an ID read or cancel another caller's response. Responses now carry the creating caller's identity (auth.GetUser), stamped at creation and compared on read/cancel/resume; a mismatch returns 404 (not 403) so existence is not leaked.

Agent workers only subscribe to agent.*, jobs.*, mcp.* and <prefix>.backend.stop; they never subscribe to backend.list, so the per-node ListBackendsOnNodeEndpoint request had no responder and timed out. The aggregate cluster-wide list already guards this in managers_distributed.go (skip nodes whose NodeType is set and not "backend"). The single-node endpoint lacked the same guard. Thread the NodeRegistry into ListBackendsOnNodeEndpoint and short-circuit to an empty (non-nil) list for non-backend node types before issuing the doomed NATS request, mirroring the aggregate-list gate so both views stay consistent.

LocalAI [bot]	64150ca7ab	fix(distributed): broadcast admin model-config changes across replicas (#10540) ... In distributed mode the admin model endpoints (/models/edit, /models/import, /models/toggle-state and the PATCH config-json endpoint) wrote the YAML to the shared models dir but reloaded only the local replica's in-memory ModelConfigLoader. With multiple frontend replicas behind one service, a save landed on whichever replica handled the request; peers kept serving their stale in-memory view, so a load-balanced request was a coin-flip between old and new config (a created alias visible on one replica and missing on the other, an edited alias target diverging, etc.). The NATS cache-invalidation channel (SubjectCacheInvalidateModels + OnModelsChanged) already existed for the gallery install/delete path; these admin endpoints simply never published on it. Wire them up via a new GalleryService.BroadcastModelsChanged helper (no-op in standalone mode). Also fix delete propagation: LoadModelConfigsFromPath is additive and never drops an entry whose file is gone, so the subscriber hook (which only reloaded from disk) could not propagate a removal. ApplyRemoteChange now honors the event op - pruning the element on "delete" and reloading otherwise - and shuts down any running instance of the affected model so the new config takes effect. This closes the same latent gap on the gallery delete path.

LocalAI [bot]	56600eec3e	fix(nodes): show a node's existing labels on the detail view (#10529) ... fix(nodes): return labels in single-node GET so the detail view shows them The node detail view (/app/nodes/:id) reads `node.labels` to render a node's existing labels, but the single-node GET endpoint returned a bare BackendNode whose Labels live in a separate table - so the list was always empty and operators could only add labels, never see what was already set (#10527). The same response also lacked in_flight_count and model_count. Add NodeRegistry.GetWithExtras, mirroring the existing List vs ListWithExtras split: bare Get stays cheap for the routing hot paths and existence checks, while the detail endpoint uses the enriched variant to attach the labels map and live counts. No frontend change is needed - the UI already renders existing labels once the data is present.

LocalAI [bot]	482314c623	fix(realtime): resolve model aliases for pipeline sub-models (#10484) ... Realtime pipeline sub-models (llm/transcription/tts/vad/sound-detection) were loaded via cl.LoadModelConfigFileByName without alias resolution, unlike top-level API requests which resolve aliases in core/http/middleware/request.go. So a pipeline that references an alias (e.g. `pipeline.llm: default`, where `default` is an alias for a real LLM) reached model loading as the alias stub with an empty Backend. This was silently broken on a single host (it failed downstream) and a hard error in distributed/p2p mode: routing model : loading model default: ... installing backend on node X: backend name is empty Fix by routing every pipeline sub-model load through a small helper that follows a single alias hop (mirroring the top-level resolution), so non-alias sub-models behave identically and aliased ones get the target's full config (Backend, Model, ...).

Richard Palethorpe	e1994579f8	fix(pii): load default detectors at startup + add LOCALAI_PII_DEFAULT_DETECTORS (#10474) ... pii_default_detectors was applied to the live config only by a live POST /api/settings (ApplyRuntimeSettings) — neither the startup loader nor the config file watcher read it back. So after a restart the persisted default detectors were dropped, and the cloud-proxy MITM listener (which resolves each intercept host's detectors once at start via ResolvePIIPolicy) came up with an empty set and forwarded intercepted traffic unredacted, even though the MITM model had pii.enabled:true and the defaults were on disk. Request-side default redaction broke the same way. - startup.go: loadRuntimeSettingsFromFile now applies pii_default_detectors, before startMITMIfConfigured, with env > file precedence. - config_file_watcher.go: apply pii_default_detectors on live file edits, matching the existing env-guard pattern used for the other fields. - settings endpoint: rebuild the MITM listener when pii_default_detectors changes (its per-host detector map is frozen at listener start), not only on a mitm_listen change — so toggling a default detector takes effect on cloud-proxy traffic immediately. - new LOCALAI_PII_DEFAULT_DETECTORS env var / CLI flag (WithPIIDefaultDetectors) so the default detector set can be pinned at boot for immutable deployments.

Echo routes such paths via URL.RawPath and stores the matched path-param value still escaped, so c.Param("name") returned "legacy-api-key%3ALiteraryResearch" and the store lookup 404'd ("collection not found"). This was second-order fallout of #10375/#10387: once colons became valid in names, the URL-decode gap surfaced on every name-bearing endpoint. Add a decodedParam helper that url.PathUnescape's the param (falling back to the raw value on invalid encoding) and wire it into all collection endpoints and the agent :name endpoints, which share the identical prefix.

POST /api/settings rebuilt runtime_settings.json from only the request body, so a focused admin page that submits a single field wiped every other persisted setting. The Middleware proxy tab (mitm_listen) and detector table (pii_default_detectors), plus the MCP SetBranding tool (instance_name/instance_tagline), all POST partial bodies; the no-omitempty api_keys and pii_default_detectors fields even round-tripped as JSON null. Read the persisted settings and overlay only the fields the request set (RuntimeSettings.MergeNonNil) before writing. Every field is a pointer, so the reflection-based merge is total over the struct and any field added later is preserved automatically. Absent or null fields are now kept; clearing a setting is done by sending its explicit empty/zero value (api_keys [], mitm_listen "", etc.), unchanged from before. The full Settings page sends every field, so its Save behaves identically.

SKETCH (backend skeleton real; core REST wiring + CI/gallery is a checklist in DESIGN.md): - backend/backend.proto: new SoundDetection rpc + SoundClass messages (run `make protogen-go` to regenerate pkg/grpc/proto). - backend/go/ced: main.go (purego dlopen libced.so + ced_capi.h), goced.go (Ced gRPC backend: Load + SoundDetection), Makefile (clone-at-pin CED_VERSION, ggml static-PIC shared build), run.sh, package.sh, .gitignore. - DESIGN.md: REST /v1/audio/classification wiring (handler/route/capability registration checklist), gallery/index + CI registration, and a scoping note for the realtime/websocket live-recognition path (sliding-window classify over the existing ws transport + voicegate; the ced C-API per-PCM entry point is already window-friendly).

Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ced): realtime sound-event detection over the websocket API When a realtime pipeline configures a sound-classification model, each VAD-committed utterance (the same window the transcription path produces) is also run through the CED sound-event classifier and the scored AudioSet tags are emitted as a new server event. No new backend rpc is needed: the SoundDetection gRPC method already exists on this branch. - config: add Pipeline.SoundDetection (yaml/json sound_detection,omitempty) beside Transcription/VAD. - realtime: add Model.SoundDetection(ctx, audio, topK, threshold) to the ModelInterface; implement it on wrappedModel and transcriptOnlyModel by calling backend.ModelSoundDetection with the session's sound-classification model config (mirrors how Transcribe dispatches). Load the optional config in newModel / newTranscriptionOnlyModel; nil config keeps it additive. - types: add ConversationItemSoundDetectionEvent (item_id, content_index, detections[]{label,score,index}) with type conversation.item.sound_detection, its ServerEventType constant and MarshalJSON, mirroring the transcription completed event. - realtime: add emitSoundDetection (unary path: classify the committed window, build the event, t.SendEvent) and wire it at the utterance-commit hook right after emitTranscription; gated on session.SoundDetectionEnabled (resolved from Pipeline.SoundDetection at session setup, defaults top_k=5, threshold=0). Its error is logged via xlog but never aborts the turn. - test: Ginkgo specs for emitSoundDetection (tags emitted, empty detections, classifier error) plus a SoundDetection method on the fakeModel double. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ced): implement SoundDetection in nodes backend test doubles The SoundDetection method added to the grpc backend interface left two test doubles (fakeBackendClient, fakeGRPCBackend) incomplete, so core/services/nodes failed to compile under `go vet`/`go test` (go build missed it: the doubles live in _test.go). Add the method to both, mirroring their existing Detect mock. Repairs CI for the nodes package. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ced): decouple realtime sound detection from VAD (sound-only sessions) Sound-event detection must activate on sounds, not speech, so it no longer runs through the voice VAD/transcription path. A sound-detection-only pipeline (sound_detection set, no transcription/LLM) now: - is accepted by prepareRealtimeConfig (sound_detection counts as a pipeline stage), - builds a lightweight model via newSoundDetectionOnlyModel (no VAD/STT/LLM/TTS loaded), and - defaults the session to turn_detection none (no VAD) with no transcription stage, so the client drives windowing via input_audio_buffer.commit (option A: client-side sliding window). The per-PCM C-API already supports arbitrary windows. commitUtterance gains a sound-only branch: it emits the conversation.item.sound_detection event (scored AudioSet tags) and stops - no transcription, no LLM response. generateResponse is now guarded on a transcription stage being present, so a sound-only turn never invokes the LLM. Existing transcription/VAD sessions are unchanged (additive). Added a commitUtterance sound-only Ginkgo spec asserting it emits the sound event and neither transcribes nor generates a response. go vet + golangci-lint (new-from-merge-base) clean; openai suite green.

The model gallery (GGUF) entry is intentionally deferred pending the HuggingFace publish (TODO note inline). - scripts/changed-backends.js: add an explicit item.backend === "ced" branch in inferBackendPath mapping to backend/go/ced/, same mechanism and ordering as the parakeet-cpp branch (before the generic golang fallthrough). - .github/workflows/bump_deps.yaml: register mudler/ced.cpp -> CED_VERSION in backend/go/ced/Makefile so the daily bot bumps the pin. - swagger/{docs.go,swagger.json,swagger.yaml}: regenerated via make swagger so the existing /v1/audio/classification annotations land in the generated spec. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ced): server-side windowing for realtime sound detection (option B) Adds an optional server-driven sliding-window classifier so a sound-only realtime client only has to stream audio (no input_audio_buffer.commit): - Pipeline.sound_detection_window_ms / sound_detection_hop_ms config knobs. When both > 0 on a sound-only session, the server classifies the last window of streamed audio every hop and emits a conversation.item.sound_ detection event; the input buffer is trimmed to one window so a long stream stays bounded. When unset, the session stays client-driven (option A). Runs independent of VAD (sound events are not speech). - handleSoundWindow (ticker) + classifySoundWindow (one tick, extracted so it is unit-testable) + writeWindowWAV, which declares the true InputSampleRate (NewWAVHeaderWithRate) so the classifier resamples correctly. Goroutine is started after toggleVAD and torn down with the session (close + wg.Wait). - Register pipeline.sound_detection (+window_ms/hop_ms) in the config meta registry; the earlier realtime commit added pipeline.sound_detection without a registry entry, failing TestAllFieldsHaveRegistryEntries. This fixes that and covers the two new knobs. Tests: classifySoundWindow emits an event + trims the buffer to one window, no-ops on too-little audio; writeWindowWAV declares the given sample rate. go build/vet + golangci-lint (new-from-merge-base) clean; config + openai suites green.

Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(realtime): add Speaker type and conversation.item.speaker event Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * refactor(realtime): split voiceGate into Resolve + authorize Split the speaker authorization into a Resolve step (embed once, produce a types.Speaker identity) and a pure authorize policy step, with a 0..100 confidence score mirroring /v1/voice/identify. The legacy Authorize wrapper is kept so existing specs stay green.

Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs(realtime): document speaker identity surfacing and personalization Document the new voice_recognition keys (enforce, identity.*) and the LocalAI-extension conversation.item.speaker server event in the realtime feature docs. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(realtime): cover when:first+identity re-resolution and multi-speaker history Add two integration specs to harden the speaker-aware realtime path: - when:first with an Identity block re-resolves the speaker every turn even though re-authorization is skipped after the first match: a later resolve error now fails closed, while a clean later resolve still surfaces and names the speaker. - multi-speaker history attribution: each user turn carries its own per-message name and the injected system note reflects the latest speaker. Test-only change; no production behavior was modified. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(realtime): surface speaker labels in conversation.item.speaker Carry the registered speaker's labels (identify mode) on types.Speaker so they flow into the conversation.item.speaker event and the stored item. Verify mode has no labels, so the field is omitted there. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(e2e): cover conversation.item.speaker over a real websocket Add a realtime-pipeline-identity config (verify mode, enforce:false, identity announce+announce_unknown+personalize) and two e2e specs driving the real server over a real WebSocket with the mock VoiceEmbed backend: an authorized speaker yields a conversation.item.speaker event naming e2e-speaker (matched true) and reaches response.done; an unauthorized speaker yields an unknown (matched false, no name) event and still responds, proving enforce:false never drops a turn. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(config): register voice_recognition enforce + identity fields The meta registry coverage test (TestAllFieldsHaveRegistryEntries) requires every config field to have an entry in core/config/meta/registry.go. The new voice_recognition.enforce and voice_recognition.identity.* fields were missing, failing tests-linux and tests-apple. Add registry entries (toggles) so the fields are surfaced in the model-config editor and the coverage test passes.

LocalAI [bot]	9565db5f94	feat(models): model aliases - redirect a model name to another configured model (#10414) ... * feat(config): add model alias field and self-validation Add ModelConfig.Alias (yaml: alias), IsAlias(), and an alias short-circuit at the top of Validate() that rejects self-reference and forbids setting backend/parameters.model on a pure-redirect alias. Assisted-by: Claude:claude-opus-4-8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(config): resolve and validate model alias targets in the loader Assisted-by: Claude:opus-4-8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(middleware): resolve model aliases and stamp requested/served identity Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(modeladmin): reject alias configs with invalid targets on create/edit Validate alias targets at create/swap entry points (ImportModelEndpoint, EditYAML, PatchConfig) so a dangling, chained, or disabled alias target is rejected at save time rather than surfacing as a runtime error. Assisted-by: Claude:opus-4-8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(api): add GET /api/aliases to list model aliases Adds an admin-gated read-only endpoint that lists every model alias config as {name, target} pairs, backed by the loader's existing GetAllModelsConfigs(). Assisted-by: Claude:opus-4.8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(mcp): add set_alias and list_aliases tools Expose model-alias management over the LocalAI Assistant MCP surface: list_aliases (read-only, GET /api/aliases) and set_alias (mutating). SetAlias is swap-first: PATCH /api/models/config-json/:name swaps an existing alias's target (validated, non-destructive) and a 404 falls back to POST /models/import to create a fresh {name, alias} config. The inproc client mirrors this via ConfigService.PatchConfig + a create path modeled on ImportModelEndpoint. Deletion reuses delete_model.

Assisted-by: Claude:opus-4.8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): add alias template card and Manage alias badge Add an 'Alias / Routing' template to the create-flow gallery that seeds a minimal name + alias config, and a read-only 'alias -> target' badge on the Manage Models tab. The capabilities row payload does not carry the alias field, so the badge resolves targets from GET /api/aliases looked up by name.

The LocalAI process is the sole reader/writer of model configs, so 0600 is correct and keeps the scan clean.

LocalAI [bot]	b081247d95	feat(config): hardware-tuned defaults — Blackwell batch + VRAM-scaled concurrency (#10411) ... * feat(config): node-aware hardware defaults — larger physical batch on Blackwell A larger physical batch (n_batch/n_ubatch) materially lifts MoE prefill on NVIDIA Blackwell consumer GPUs (sm_120/121, incl. GB10 / DGX Spark) — measured on a GB10 with Qwen3-Coder-30B-A3B, the prefill ceiling rises (ub512 ~2994 -> ub2048 ~3316 t/s) and saturates around 2048. The heuristic lives in core/config alongside the other config overriders (ApplyInferenceDefaults, guessDefaultsFromFile/NGPULayers) — they all fill the ModelConfig from heuristics, so hardware tuning is the same domain and stays in one place. It is parameterized on a GPU descriptor (not direct detection) so it works in both deployment shapes: - Single host: SetDefaults applies it with the LocalGPU. - Distributed: only the worker sees the GPU, so the worker reports its compute capability on registration (gpu_compute_capability -> BackendNode), and the router re-applies the SAME core/config heuristic for the SELECTED node before loading — fixing the case where the frontend has no GPU at all. Explicit `batch:` always wins (only managed default values are touched). xsysinfo gains NVIDIAComputeCapability() (detection only); all interpretation lives in core/config. Tests: core/config, pkg/xsysinfo, core/services/nodes. Assisted-by: Claude:opus-4.8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(config): injectable local-GPU seam + single-instance coverage Make local GPU detection an injectable package var (localGPU) so the single-instance path (SetDefaults -> ApplyHardwareDefaults) is deterministically testable without a real GPU, mirroring the distributed override's coverage. Adds specs asserting SetDefaults sets the Blackwell physical batch, leaves it unset on non-Blackwell, and never overrides an explicit batch. Assisted-by: Claude:opus-4.8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(config): default concurrent serving (n_parallel) by GPU VRAM The llama.cpp backend defaults n_parallel=1, which serializes multi-user requests and leaves continuous batching off (it auto-enables only at n_parallel>1). Fold a VRAM-scaled parallel-slot default into the hardware-config path so multi-user serving works out of the box: >=32GiB->8, >=8GiB->4, >=4GiB->2, else unchanged. With the backend's unified KV the slots SHARE the context budget, so this adds concurrency without multiplying KV memory. Explicit parallel/n_parallel always wins. EnsureParallelOption is shared by the single-host path (ApplyHardwareDefaults with the local GPU) and the distributed router (per selected node's reported VRAM, since the frontend may have no GPU). LocalGPU now also reports VRAM.
