localai-org-maint-botandlocalai-org-maint-bot c525ad16e8 fix(audio): record transcription usage and traces (#12546)
* fix(audio): record transcription usage and traces

Count successful transcription requests by model, including streams.
Keep token counts at zero because transcription exposes no token usage.

Capture multipart API trace metadata without reading uploaded audio.
Do not record failed transcription or client writes as successful usage.

* fix(audio): preserve aliases in streaming usage

Streaming transcription records the resolved target as its usage model.
Pass the requested name so JSON and SSE requests share the alias bucket.

localai-org-maint-botandEttore Di Giacinto 6b794651a4 feat(diarization): return sound events with include_sounds (#12544)
* feat(diarization): return sound events with include_sounds

A client that wants text, speakers, voice prints and sound events had to
make a diarization call and a separate sound call. Add an include_sounds
request field to /v1/audio/diarization that adds a sounds array of closed
events {start, end, label, confidence}, in seconds.

The parakeet-cpp backend runs a tagger-only scene stream over the clip,
the same stream and thresholds the live path uses, so a clip gives the
same events offline and live. A model with no sound_model companion, or a
backend that does not report sound events, fails with 501 and the stable
code include_sounds_unsupported instead of an empty list. The proto
carries sounds_included so an empty list still means "nothing heard".

The localai-proxy backend forwards the field. Swagger, docs and the
e2e mock backend are updated.

* feat(gallery): add parakeet-cpp-multilingual-diarization-speakers-sounds

Same as parakeet-cpp-multilingual-diarization-speakers (TDT 0.6B v3,
Nemotron-3-Diarization, WeSpeaker) plus a CED-Tiny sound_model, so one
model name serves /v1/audio/diarization with include_text,
include_speaker_profiles and include_sounds. It declares the
sound_classification usecase like the realtime scene entries.

Ettore Di Giacinto fa25493c9e feat(config): let parakeet-cpp declare the speaker_recognition usecase
parakeet-cpp now implements VoiceEmbed and VoiceVerify, so list them in
its backend capabilities together with the speaker_recognition usecase.
The usecase is not guessed, because most parakeet models have no
speaker encoder: a bundle declares it in known_usecases, which is
enough for /v1/voice/* and for voice_recognition.model.

Add a realtime pipeline test where one bundle model names the vad,
transcription, sound_detection and voice_recognition stages and the
gate resolves the speaker through the backend's VoiceEmbed.

Ettore Di Giacinto 1d117292b1 feat(voice): name registered speakers through a bundle speaker component
Naming read only speaker_model:, so a parakeet-cpp bundle that sets
speaker_component:voice never received the registered voices, in live
transcription or in diarization.

Resolve speaker_component: when speaker_model: is not set. A component
is not an encoder file, so no file-name tag is derived for it: voices
with a hash or family identity and untagged voices reach the backend,
and a voice with only a file-name tag matches through the new optional
speaker_tag: alias. speaker_model: still wins, including when it points
at the bundle file.

The bundle gallery entries do not declare speaker_recognition: that
usecase means the VoiceEmbed and VoiceVerify RPCs, which the backend
does not serve, and it selects the default model for /v1/voice/*. The
pinning test now says so.

nexxtmobile.deandnexxtmobile.de 4d681b7f6d fix(realtime): detach VAD-commit transcription from barge-in cancellation (#12446)
* fix(realtime): keep VAD-commit transcription alive across barge-in, cancel it at teardown, order commits

Barge-in (new speech onset) cancels the turn's SourceVAD response context
(realtime_turncoord.go: respSink.cancel(SourceVAD)). The VAD commit body
runs under that same context, so an in-flight Whisper STT call was aborted
with 'context canceled' whenever the caller kept talking while the first
chunk was transcribing. The user's turn was lost: no transcript, no
LLM/TTS response.

v1 of this fix ran the transcription with context.WithoutCancel(ctx). The
review correctly pointed out two correctness gaps:

1. Teardown lost its cancellation. WithoutCancel detaches from every
   cancellation, so a transcription in flight at session close outlived
   the session and blocked respSink.shutdown (which joins the response
   goroutines) until the backend finished the job.
2. Out-of-order commits. Consecutive commits run in parallel goroutines,
   so a fast second transcription could append its user item before a
   slow first one: the conversation became [second, first] and the second
   response saw only [second].

Changes (core/http/endpoints/openai/):
- Session gains a session-lifetime context (sessionCtx), cancelled by
  conncoord's Teardown BEFORE respSink.shutdown joins the response
  goroutines. The transcription (and the voice-gate resolution) run under
  it: they survive barge-in (which cancels only the per-response context)
  but are cancelled with the session.
- Commit slots order the user-item appends in speech order:
  Session.nextCommitSlot() is claimed at commit issue time (VAD CommitTurn
  / client commit), a commit's item append waits on the previous slot's
  done (aborts on the session context), and every exit closes the slot so
  a failed or torn-down commit never blocks the next. Transcriptions stay
  parallel; only the appends are ordered.
- If the turn's response context was cancelled while the (detached)
  transcription ran — barge-in, superseded by a newer commit — the user
  item still commits (appendUserItem, split out of generateResponse) so
  the LLM context keeps the full user input, but no response is generated
  for the superseded turn; the newer speech triggers its own response on
  the complete history.
- Regression tests (realtime_commit_order_test.go) cover both review
  schedules — teardown during an in-flight transcription, and
  held-first/finished-second out-of-order completion — plus the
  barge-in-during-transcription item survival, driving the real commit
  path with a transcription double that honours context cancellation.
- docs/design/realtime-state-machines.md: implementation-status entry for
  the committed-turn pipeline (transcription lifetime + commit order).

Fixes #12445

Validated: builds, go vet clean, all openai specs + respcoord/turncoord/
conncoord suites pass under -race (incl. the 3 new regression specs).
Production A/B (call-center voice agent, SIP, silero-vad +
whisper-large-turbo + LLM + TTS, server_vad ~600 ms) on LocalAI v4.11.0:
unpatched — 'transcription_failed: context canceled', first part of the
utterance lost, agent answers only the remainder; patched — full
transcript committed, agent answers the complete utterance, barge-in
still cancels the in-flight assistant TTS response as intended, and
teardown cancels the in-flight transcription instead of waiting for the
backend.

* fix(realtime): release commit slots in order on every exit; share slot+issue boundary

Follow-up to the review of c8f991be (issue #12445): two schedules still
broke commit ordering.

1. A failed middle commit released later turns before earlier turns
   finished. slot.done closed on every return, but the wait on
   slot.prevDone happened only on the successful nonempty-transcript
   path. Hold transcription A, let B fail (or return an empty
   transcript / be rejected by the voice gate), then complete C: B
   closed its channel without waiting for A, so C appended and started
   its response without A (response history [third], final history
   [third first]). Fix: the slot now releases (done closes) only AFTER
   the predecessor has finished — on EVERY exit path, including errors,
   empty transcripts, gate rejections and teardown (the session context
   can still stop the wait, so teardown never blocks on a
   never-finishing predecessor). The success path keeps its append gate
   (wait before appending the user item); the deferred release gate
   enforces the same order on every other exit.

2. Slot order and response issue order could disagree between the two
   producers. The VAD CommitTurn and the client
   input_audio_buffer.commit reserved the slot and called
   respSink.issue separately; a pause between the two let the other
   producer reserve AND issue first, so the later issue superseded the
   EARLIER turn's response (response history [first], final history
   [first second], second turn un-answered). Fix: both producers now go
   through Session.issueCommit, which claims the slot and issues the
   body under one lock (commitOrderMu) — slot order == issue order.
   respSink.issue is non-blocking, so the lock never stalls
   VAD/barge-in handling.

Regression tests (realtime_commit_order_test.go) now drive the REAL
issue path — Session.issueCommit into the real responseSink/respcoord,
so coordinator supersession and the spawned response goroutines are
exercised — and cover: teardown during an in-flight transcription;
held-first/finished-second out-of-order completion; barge-in
(respSink.cancel) item survival; a FAILED middle commit; an EMPTY
middle commit; interleaved VAD/client producers in both directions.
The failed/empty middle specs fail deterministically without the
release gate (verified against the pre-fix code).

docs/design/realtime-state-machines.md: implementation-status entry
updated (append gate + release gate + shared issue boundary).

Validated: builds, go vet clean, all openai specs + respcoord/turncoord/
conncoord suites pass under -race (476 specs, incl. the 4 new ones).

* test(decisions): isolate fixture globals

Disable optional global services in the isolated HTTP fixture and register
cleanup before setup assertions. Verify meter provider identity survives
fixture creation and destruction.

Snapshot observed usage before assertions so failures cannot retain the

* fix(application): honor optional telemetry controls

Skip failover gauge registration when metrics are disabled. Register
against the application meter rather than looking up the global provider.

Allow embedders to retain the bounded routing log without billing stats.
Keep the existing default when stats are disabled. The isolated HTTP

Broadcaster is the fan-out half of MessagingClient. The NATS client and
the in-memory FakeBus now refuse a subject outside the served roots and any
wildcard other than a whole single token, and FakeBus shares MatchSubject
instead of its own copy. FakeBus Unsubscribe now removes its own
subscription instead of the first one with the same subject.

A shared conformance suite in messagingtest runs against both carriers.

finetune/service.go, quantization/service.go and

because it only calls Subscribe, which lets the narrowed consumers use it.

Stayed wide: worker/supervisor.go, because its client field also serves

queue and wiring files (nodes/unloader.go, nodes/file_stager_s3.go,
jobs/dispatcher.go, agents/dispatcher.go, agents/events.go,

An agent worker started with a custom LOCALAI_AGENT_SUBJECT such as
tenant-a.agent.execute used to start and then wait on a subject the
frontend never publishes to. After the subject rules landed it exited
at subscribe time with an error that did not name the setting.

Behaviour change: the worker now checks LOCALAI_AGENT_SUBJECT before it
registers or connects, and exits with an error that names the variable
and says to use a served subject under the agent root, for example
agent.execute. The served roots are not widened: a custom root was
never delivered by the frontend, and a wider set would reopen the
drift the subject rules exist to close. The flag help and the agent
worker docs state the constraint.

* test(nodes): pin the reactions to ErrNoRoute

Three callers react to ErrNoRoute and had no spec: the reconciler's
upgrade drain falls back to the legacy forced install, the reconciler
marks the node unhealthy when a pending op has no route, and the
backend-op fan-out marks the node unhealthy. Each spec drives the real
caller with a scripted no-responders reply and reads the result from
the registry or the recorded requests.

A fourth spec pins the other side: a pending op that times out leaves
the node healthy and only counts the attempt, so mapping timeouts onto
ErrNoRoute would fail here.

Add specs that call Publish, Request, Subscribe, QueueSubscribe,
SubscribeReply and QueueSubscribeReply on a client with no connection.
Each call must return ErrUnservedSubject for bogus.thing and
ErrUnsupportedWildcard for jobs.>. This proves that the subject check
runs before the connection is used, and needs no server.

The NATS conformance suite is the only check that runs the subject rules
against a real carrier. Before this change it skipped without output
when Docker was missing. Now it fails when CI is set, so a Linux runner
without Docker cannot hide it. It still skips on local runs and on macOS
CI, which has no Docker.

Add SubjectNodeBackendInstallProgress to the list of constructors that

* docs: state what ErrNoRoute may change, and group the distributed guides

The seams note said MarkUnhealthy was the only state change allowed
on ErrNoRoute. A pending backend op still records the failed attempt,
counts toward the reconciler's retry limit and is dead-lettered after
the maximum attempts. The note now says that MarkUnhealthy is the only
change to the node's own state, and that the per-op accounting is not
a verdict about the node.

The note also documents that the NATS conformance run fails under CI
when Docker is missing. The distributed-seams row moves next to the
distributed-state row in the topics table. The liveness ping spec
header now says no route is a reason to skip the worker, not proof
that the worker is gone.

The malformed-request log lines are restored for install, upgrade, backend.delete, model.unload, model.stop and model.delete, with the reply bytes unchanged. The signal adapter is renamed noReply, which also lets worker.go import os/signal without an alias again.

Enqueue publishes the payload as Publish does today, with one JSON marshal. FakeBus now records queue groups and keeps reply handlers so later specs can pin and drive them.

The job dispatcher, the agent pool and the agent scheduler enqueue through messaging.WorkQueue; the NATS implementation publishes to the same subjects as before.

The handlers become typed mcp.ToolHandler and mcp.DiscoveryHandler values that answer every failure with a reply carrying Error.

Queue group (agent-workers), inline execution on the delivery goroutine, the background handler context, the unmarshal error reply texts and the reply-less backend stop subscription are unchanged. The backend stop handler takes the decoded backend name, so it can still close that backend's MCP sessions.

SubjectJobCancelWildcard lost its last subscriber when the frontend

decodeBackendStopRequest returned a stopAll flag that production dropped
and only a test read. decodeBackendStop is now the single decoder with the
same semantics: an empty body is stop-all, an empty Backend is stop-all,
malformed JSON is an error. stopBackends still derives stop-all from
Backend, so no reply changes.

* fix(messaging): keep an explicitly empty agent queue a plain subscription

Before the work queue seam the agent worker passed LOCALAI_AGENT_QUEUE
straight to QueueSubscribe, so an explicitly empty value made a plain
subscription and every agent worker ran every agent run.
WithAgentRunRoute replaced an empty queue with agent-workers, which
silently changed that.

Keep the queue as given once the option is applied. An empty subject still
falls back to agent.execute, since it never had a meaning of its own. The
flag default stays agent-workers, so only an explicitly empty value

second carrier notes to the developer note: the reconciler has no
ClientFactory option, the logs proxy honours HTTP_PROXY, verbs one carrier

agent runs publish through the NATS-bound EventBridge, which is not an

the names.

* feat(parakeet-cpp): name speakers in the live scene stream

The live scene stream now begins with a known-voice registry when a
speaker model is loaded and the live config carries voices, and each
closed speaker segment takes its slot's current name from the feed's
names map. A segment that closes before its slot is identified has an
empty name. The registry is freed after the stream, on every path.

* fix(parakeet-cpp): skip an unusable registered voice instead of failing the request

A registered voice with the wrong embedding size, or one the C side

the model for every user. Skip such voices with a warning that does not
carry the voice name, and take the plain path when none is left.

Also map an exact 0 speaker threshold or margin to a tiny positive value,

in parakeet.cpp since: the voice identification change (C-API v9, #78) and
raw-embedding enroll plus diarize-only speaker naming (C-API v10, #79).

New real-library specs (gated on PARAKEET_BACKEND_TEST_SPEAKER_MODEL,
_DIAR_MODEL, _WAV and, for the live path, _STREAM_MODEL) name the two
speakers of two_speakers.wav from a committed pair of WeSpeaker embeddings,
with the voices passed in reversed order. They also check that the float32
threshold reaches C through purego. The shared test loader now registers
the v9/v10 and scene symbols as main.go does.

2fa36e7147 feat(parakeet-cpp): speaker diarization, sound detection and live scene events (#12335)
* feat(parakeet-cpp): load diarization and CED models and companions

Repin PARAKEET_VERSION to parakeet.cpp PR #75's head, which adds
parakeet_capi_model_kind (ABI v8). Bind the new diarization, sound
event and combined scene stream C symbols through the same
purego.Dlsym probe pattern already used for the batched JSON entry
point, so the backend still loads against an older libparakeet.so.

Load now classifies the loaded GGUF by role (ASR, diarization or
sound) via parakeet_capi_model_kind and can load up to two companion
models from Options[] (asr_model:, diarization_model:, sound_model:,
paths resolved against opts.ModelPath), verifying each companion's
kind and freeing every context opened so far on any failure. Free
releases the primary and every companion. AudioTranscription now
names the loaded role when it is not ASR instead of a generic model
not loaded error. The dynamic batcher starts only when an ASR context
ends up loaded, primary or companion.

This is groundwork only: the Diarize and SoundDetection RPCs and the
live scene stream that actually use these new roles land in later
commits.

* feat(parakeet-cpp): add speaker diarization

Implement the Diarize RPC for the parakeet-cpp Go backend, wired to
Nemotron-3-Diarization through libparakeet.so's diarization C-API.

Plain diarization uses parakeet_capi_diarize_pcm; when include_text is
set and an ASR companion is loaded, parakeet_capi_transcribe_and_
diarize_json fills each segment's text instead. Speaker labels are the
decimal index, or "unknown" for -1 (no diarized speaker overlaps).
min_duration_off merges same-speaker segments across a short gap
before min_duration_on drops the segments still too short, then ids
are renumbered. num_speakers/min_speakers/max_speakers/clustering_
threshold have no Sortformer equivalent and are logged at debug
instead of rejected.

Verified against the real Nemotron-3-Diarization + parakeet-tdt_ctc-

speaker segmentation and matching speaker-attributed transcripts.

* feat(parakeet-cpp): add sound event detection

Wire the SoundDetection RPC to the CED tagger context (p.tagCtx)
loaded by Task 1's role classification. It runs the whole clip
through a one-shot parakeet_capi_sound_stream_* session (window
10s, hop 10s, top_k set to the tagger's class count so every
drained window carries a full score list), averages each class's
score across the drained windows, sorts descending, then applies
the request's threshold and top_k (0 keeps every class).

No tagCtx returns FailedPrecondition; a libparakeet.so missing the
sound_stream symbols returns Unimplemented. Every C call runs under
engineMu, and the stream is always freed, even when a feed or drain
call fails partway through.

Verified against a real ced-tiny-q8_0.gguf on the rooster.wav demo

SoundDetection now checks ctx before each 10 s feed slice (mirroring
driver.go's feedSlices) and returns Canceled if the caller gave up,
so a long clip can be interrupted instead of feeding to completion
regardless. The stream is still freed on every path, cancellation
included.

Also narrow engineMu to the C calls: the drained JSON document is
now decoded after the lock is released, splitting soundStreamScores
into a locked soundStreamDrain (opts, begin, feed, drain, free) and

* feat(parakeet-cpp): stream speaker and sound events during live transcription

Add two additive proto fields, LiveSpeakerSegment and LiveSoundEvent,
repeated on TranscriptLiveResponse. When a diarization or sound
companion model is loaded, AudioTranscriptionLive now runs a no-ASR
scene stream (parakeet_capi_scene_stream_begin) beside the ASR
streaming session, feeding it the same PCM slices and forwarding any
closed speaker or sound events alongside the matching ASR delta, or
on their own when a slice has no ASR output.

The scene stream is freed and reopened on a mid-stream Config reset,
flushed with is_last before the closing FinalResult, and degrades
gracefully (a warning, not an error) when begin or a later feed call
fails, so live transcription keeps working ASR-only. Existing live
behavior is unchanged when no companion is configured, and no scene
C call is made in that case.

* fix(parakeet-cpp): keep scene events off the ASR critical path in live

Emit each slice's ASR result right after the ASR feed, before the
scene feed for that slice runs, so a companion diarization/sound
model never adds scene compute latency in front of the delta or
<EOU> that drives realtime turn detection. Closed speakers/sounds go
out afterward as their own response, so a slice with both now
produces two responses, ASR first. The live feed log line now
reports ASR and scene wall time separately.

Re-check the diarization/sound contexts a scene stream was begun
with against the live contexts before every feed, under the same
lock: Free() can race between an ASR feed and the matching scene
feed and free the model the stream borrows. A mismatch now returns
without touching the C side. Freeing the stream itself stays
unconditional; the scene stream's destructor only releases its own
buffers and never touches the borrowed contexts.

Also recover a panicking stub inside the live test goroutine instead
of crashing the test binary, and reset the live decode-lag tracker on
a mid-stream config reset, matching what its own comment already
promised.

Each speaker segment emits
conversation.item.input_audio_transcription.segment with speaker,
start, end and empty text under the turn's item id. Each sound
event emits conversation.item.sound_detection with one tag

context silently overwrote ctxPtr/diarCtx/tagCtx, and Free() only
walks those three fields, so the original primary context was never
freed again.

Reject a companion whose role the primary already holds before its
GGUF is even loaded, freeing everything loadRoles opened so far, the
same way a wrong-kind companion is already rejected.

Also warn, rather than silently fall through, when
parakeet_capi_model_kind reports PARAKEET_MODEL_KIND_NONE for a

sceneBegin started the live diarization/sound companion stream with
the C API's default sound options, whose top_k keeps 5 scores per
window forever until drained. The live scene path never drains sound
scores (only the offline SoundDetection RPC does, with its own fresh
stream), so this window queue on the C side grew for the whole
session's lifetime.

Set opts.Sound.TopK = 0 before starting the scene stream: this
disables score retention while leaving sound event detection (onset/
offset), which the live path actually consumes, unaffected.

mergeCloseSegments only compared neighbors in the single start-sorted

the adjacency the merge relied on. Group segments by speaker first,
merge within each speaker's own start-ordered run, then re-sort the
result by start so interleaved speakers come back out in timeline
order.

Also harden Diarize's entry points the same way streamFeedDoc/
sceneFeed already are: diarizeCall re-checks p.diarCtx (and, on the
include_text path, p.ctxPtr) under engineMu right before the C call,
so a Free() racing between Diarize's own checks and the lock can no
longer reach the C side with a freed context. When the include_text
call returns NULL, last_error is now read from both contexts and
whichever came back non-empty is reported, since either side of the
pairing can be the one that failed. A WAV decode failure is reported
as InvalidArgument instead of an unwrapped/untyped error.

* docs: fix the parakeet-cpp companion role table and realtime scene docs

audio-to-text.md's companion option table read "Use on" with a note
that the loader did not enforce the pairing; it now rejects a
companion whose role duplicates the primary's, so restore the
"Allowed on" wording and describe the real enforcement.

openai-realtime.md's live speaker/sound section claimed a mid-stream
session.update resets the companion stream and that it flushes on
session close; neither happens, since the realtime core opens one
live stream (and so one scene stream) per speech turn and closes it
at that turn's commit, with no mid-stream Config in between. Document
that lifecycle instead, state precisely that start/end are seconds
from the start of the turn's own audio, and note that the diarization
model starts a fresh session every turn, so a speaker index is only
meaningful within one turn. The example sound tag ("Rooster", index
17) did not match any real CED label; index 17 in ced-tiny-q8_0.gguf
is "Baby laughter". Replaced with "Chicken, rooster" at its real

* feat(transcription): carry speaker labels on words and streamed segments

A diarizing backend could label transcript segments, but two paths
dropped the label: TranscriptWord had no speaker field, so live
transcription words and word-level timestamps could not carry one, and
the stream=true transcript.text.done event left the speaker out of
its segments.

TranscriptWord gains an optional speaker (proto field 4, additive).
It flows through the live event and result mapping, the JSON word
output of the endpoint and the CLI, and transcript.text.done now
includes a segment's speaker when there is one. Empty labels are
omitted, so responses without diarization are unchanged.

Speaker events reached a realtime session only from the live

pipeline.diarization (off by default) asks the transcription model for
speaker labels on each committed turn and emits every labelled segment
as a conversation.item.input_audio_transcription.segment event, with
its text, before the turn's completed event. It is opt-in because some

pipeline.diarization, and each committed turn gets speaker segments
and sound tags from one parakeet-cpp backend.

diarization and CED-Tiny entries. A real-model spec checks the

Measured on CPU over a 37 s clip: the live diarization + sound stream

Tai Anandlocalai-org-maint-bot eec532704c fix(functions): honor function_arguments_key when building the tool grammar (#11677)
* fix(functions): honor function_arguments_key when building the tool grammar

All four call sites of `Functions.ToJSONStructure(name, args string)` pass
`FunctionsConfig.FunctionNameKey` as *both* arguments, so
`FunctionArgumentsKey` never reaches the grammar generator.

`ToJSONStructure` writes the two properties into the same map:

    property[nameKey] = FunctionName{Const: function.Name}
    property[argsKey] = Argument{...}

When `nameKey == argsKey` the second assignment overwrites the first, so a
model configured with `function_name_key` gets a grammar carrying only the
arguments object -- the `{"const": "<function name>"}` constraint is gone and
the grammar can no longer express which function was called.

With `function_name_key: function`, the generated property set collapses from

    {"function": {"const": "get_weather"}, "arguments": {...}}

to

    {"function": {"type": "object", "properties": {...}}}

Setting only `function_arguments_key` is equally broken in the other
direction: the grammar keeps emitting `arguments` while `ParseFunctionCall`
(pkg/functions/parse.go) looks up the configured key, so the parsed call comes
back with its arguments empty.

The default configuration is unaffected -- with both keys empty
`ToJSONStructure` falls back to `name`/`arguments` for both parameters, which
is why this went unnoticed.

The existing `ToJSONStructure()` unit test already calls the helper with two
distinct keys, so only the call sites were wrong. Extend that test with a case
that keeps both custom keys distinct and asserts the two properties survive.

Ettore Di Giacinto 27ceda46b0 refactor: name the realtime pipeline stages with constants
Review asked for constants instead of the stage literals ("vad",
"transcription", "llm", "tts", "sound_detection") passed to resolveStage,
stageCall and isChainStage, so the uses can be cross-checked. Add
PipelineStage* constants next to the Pipeline type in core/config: the

realtime endpoint both need them.

Use them in realtime_model.go (stage routing and preload roles),
realtime.go (the voice_recognition preload role) and core/backend
preload.go. model_failover events take their stage from the stageChains
keys, so they now carry the constants too. The failover tests use the
constants for inputs and keep literal wire values in their event

Ettore Di Giacinto 14c692098e fix(openai): answer 400 for a missing or malformed audio upload
TranscriptEndpoint, DiarizationEndpoint and SoundClassificationEndpoint
returned the raw c.FormFile("file") error. Echo turns a non-HTTPError into
a 500, so a request with no multipart boundary or no file field looked like
a server fault. This became visible in tests/e2e once the suite registered
a transcription-capable model (lp-transcription) at runtime: the
default-model middleware then resolves a model, the request reaches the
handler, and "should return mocked transcription" got a 500 in some spec
orders (seed 1790493709).

Read the upload through a small uploadedFile helper that maps any
FormFile failure to 400 with the field name and parser reason. Server-side
failures after that (temp dir, file create, copy) stay 500. The image and

Ettore Di Giacinto 132bb216a1 fix(failover): resolve chains in transcription and sound-only sessions
Transcription-only and sound-detection-only realtime sessions passed a
chain config straight to the model loader. It has no backend, so the
loader fell back to greedy backend auto-detection: slow, and ending in
an unhelpful error. Sound-only sessions are a main use of chains.

The stage routing of the full pipeline moves into a stageRouter that
both realtime model kinds embed. Every stage resolves to the chain's
active target at build time and goes through the failover plan per
call. The session sends failover events for any model with chain
stages, and restarts them when a transcription session.update swaps
the model.

* fix(openai): return an HTTP error when a stream fails before any chunk

A streamed chat request set the SSE headers, then waited for the
backend. When the backend failed before the first token, LocalAI sent
a 200 with a `data: {"error":...}` chunk and [DONE]. Clients that do
not parse error chunks saw an empty reply. cogito's LocalAI client was
one of them: nib users got "streaming decision produced no content"
instead of the context overflow that caused it.

Nothing has been written at that point, so the handler now returns the
error as a normal HTTP response. A failure after the first chunk keeps
the in-stream error chunk.

A prompt that exceeds the context is now a 400 on both paths, as in

kept whole, because clients read the token counts from it.

Richard Palethorpe d10374f849 feat(router): make KNN a first-class classifier with a persisted, curated corpus (#10652)
* feat(router): make KNN a first-class classifier with a persisted, curated corpus

Add `classifier: knn` — similarity-weighted voting over labelled
example prompts. Unlike score/colbert it needs no classifier model:
label knowledge lives in a corpus seeded and curated through the
admin API, so routing decisions are deterministic, auditable, and
grounded in graded experience rather than a model's opinion.

Epistemic gate: corpus entries below knn.similarity_threshold cannot
vote; when none clears it the classifier activates no labels and the
router uses the fallback — a prompt unlike all labelled experience is
treated as undecidable, not guessed. Decisions record
nearest_similarity (also on fallback rows) so admins can see how far
the nearest labelled experience was; the Routing tab explains
out-of-corpus fallbacks and shows per-label corpus counts.

Persistence: one JSONL file per router under
<data path>/router-corpus (text, labels, vector, embedder
fingerprint). The file is the source of truth; the local-store index
is rebuilt from it at classifier build time and stays a pure
in-memory index. Entries recorded under a different embedding model
re-embed on load. Also corrects the docs' false claim that
local-store collections persist — the embedding cache never survived
restarts (and still doesn't); the corpus does.

Corpus input is API-only by design (entries may contain example user
content): POST /api/router/{name}/corpus seeds (labels validated
against declared policies, embedded server-side, indexed
immediately), GET .../corpus/stats inspects — label counts only,
entry texts are never returned by any surface — DELETE .../corpus
wipes. Admin-gated like the sibling router endpoints, and exposed as
MCP tools (seed_router_corpus / get_router_corpus_stats /
clear_router_corpus) in both the httpapi and inproc clients with
coverage-test route mappings.

Plumbing: VectorStore gains SearchK (top-K was hardcoded to 1);
local-store gets InsertBatch/Delete as optional fast paths;
RouterConfig gains a knn block (embedding_model, k,
similarity_threshold, vote_threshold, store_name) with meta-registry
fields; the classifier dropdown now offers knn and the
previously-missing colbert; embedding_cache is ignored (with a
warning) for knn — it IS an embedding-KNN lookup; the stale
/api/instructions intelligent-routing entry is rewritten (it
described a classifier that no longer exists); swagger regenerated.

Tests: KNN vote/gate specs with hand-computed vote shares, corpus
manager suite (restart reload without re-embedding, fingerprint
re-embed, dedupe, hostile store names), middleware specs (corpus
routing, gate fallback, config validation, cache-wrap refusal),
corpus endpoint specs pinning the texts-never-returned contract, MCP
catalog + route-mapping gates, and a Playwright spec for corpus
stats and the out-of-corpus decision detail.

* feat(router): name consulted corpus neighbours in knn decisions

Every knn decision (decision log rows and the /api/router/decide
response) now carries neighbors: the K retrieved corpus entries by
descending similarity - including ones below the epistemic gate, which
is what makes fallback decisions diagnosable - each as {id, similarity,
labels}. The id is the entry's content hash (first 8 bytes of the
SHA-256 of its text, hex): stable across reseeds and re-embeds, and
text-free, so an external platform that seeded the corpus can recompute
text->id on its own copy and bucket decisions by corpus region (per-
region reliability accounting) without corpus text ever leaving the
server. A corrupt index payload surfaces as an id-less neighbour at a
real similarity instead of disappearing.

* refactor(router): deduplicate knn plumbing and cut corpus hot-path waste

Post-review cleanup of the knn-first-class-router branch; no behaviour
changes on the API surface.

Reuse/altitude:
- RouterKNNConfig.ResolvedStoreName is now the single source of the
  router-corpus-<name> default (was hand-derived in four files).
- corpus.ResolveKNNRouter + corpus.Seed carry the shared model
  resolution and seed validation; the REST endpoints and the assistant
  MCP client are thin transport adapters over them, with sentinel
  errors mapped to HTTP statuses at the echo boundary.
- middleware.NewClassifierDeps assembles the classifier dependency set
  once for all five entry points (OpenAI, Anthropic, realtime, decide,
  corpus) instead of five hand-copied literals.
- router.AllClassifiers feeds both the status endpoint and the
  unknown-classifier error, ending the classifier-list drift.
- Per-classifier requirements moved out of validateRouterPolicies into
  their buildClassifier arms; the knn arm owns its embedding_cache
  opt-out instead of a name-check in the shared wrap tail.
- adminOnly replaces four inline copies of the admin gate in the
  middleware routes.
- localVectorStore.Search delegates to SearchK (identical traces).

Efficiency:
- Manager.Add embeds outside the manager mutex and appends to the
  JSONL file (O(new) instead of O(corpus) rewrite); a torn tail from a
  crash mid-append is tolerated on read and repaired on next write.
- Stats memoises per store keyed on the file's stat fingerprint and no
  longer takes the manager mutex, so the 5s status poll stops parsing
  vector-laden JSONL and stops blocking behind seeds.
- KNN Classify decodes each neighbour payload once (was twice) and
  builds refs and votes in a single pass with one fallback return.
- Corpus file writes fsync before rename/close.
- The corpus manager is built eagerly in newApplication (sync.Once
  dropped); test helper dead branch removed.

Dimitris Karakasilis 3636fcbd38 fix(realtime): keep the ICE interface allow-list working with a fixed UDP port (#11466)
LOCALAI_WEBRTC_ICE_INTERFACES was silently ignored whenever
LOCALAI_WEBRTC_UDP_PORT was set. Every interface was gathered regardless
of the allow-list, so a browser was handed the docker0/veth addresses the
setting exists to suppress, and the connection established on a good pair
and then dropped when consent checks failed on the unreachable ones.

Two things combine to cause it. A mux built over a wildcard socket makes
pion derive its host candidates by enumerating interfaces itself, with a
nil filter and loopback included. Independently, the muxed gathering path
in pion/ice never consults SetInterfaceFilter, so setting it has no effect
there either.

Bind one socket per admitted interface address via NewMultiUDPMuxFromPort,
which takes the filter, instead of one wildcard socket. All the sockets
share the same port, so the firewall requirement is still a single rule.
Networks are pinned to UDP4 to match the socket family this replaces.

An allow-list that matches no address on the host now reports the
misconfiguration rather than binding nothing and leaving signaling to
succeed while no candidate is ever advertised.

Two tests: one asserts an unmatched allow-list is an error, and one gathers
against a real peer connection and asserts no address outside the allowed
interface appears (skipped on single-interface hosts).

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.

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.

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.

generic message.

* 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.

* perf(llama-cpp): score all candidates in one batched decode

One scoring call is now a single SERVER_TASK_TYPE_SCORE task: the slot
decodes the shared prefix (prompt + longest common candidate token
prefix) once, then forks one sequence per candidate off it
(metadata-only for the unified KV cache, copy-on-write for recurrent
state) and decodes every candidate's unique tail in one llama_decode.
Previously each candidate was its own task that restored the boundary
checkpoint and re-decoded its full tail sequentially, paying
per-candidate task and decode overhead.

The context reserves SERVER_SCORE_FORK_SEQS extra sequence ids (and
recurrent-state cells) beyond the parallel slots via the new
common_params::n_seq_score_forks. Forking requires the unified KV cache
(already this backend's default) since per-sequence streams would shrink
n_ctx_seq; an explicit kv_unified:false disables forking and Score calls
that need it fail cleanly. Candidates beyond the fork/output budget
decode in successive chunks.

Wire contract and scores are unchanged: per-token logprobs are stitched
from the shared region and the forked tails. Verified bitwise
deterministic call-to-call and independent of candidate order (no
cross-fork leakage via equal-length candidate swap); ranking matches the
per-candidate implementation on the drone battery (winner softmax
0.99996 vs 0.99997), and >16-candidate chunking, prefix-of-another and
empty candidates all pass.

Measured on a desktop CPU: warm /api/score calls 0.52s -> 0.23s; warm
realtime classifier turns 196-303ms. The 9-candidate drone turn decodes
~17 unique tail tokens in one batch instead of nine sequential ~220ms

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.

* feat(realtime): splice filled slot values into classifier replies

A classifier option's spoken reply can now reference its tool's argument
slots ("Going forward {{distance}} {{units}}."): the values inferred by
the slot-fill completion — or the recovery defaults — are spliced into
the reply as plain text before it is emitted, so what the assistant says
confirms what it actually inferred. Placeholders without a value stay
literal, and options without slots are untouched.

FillToolArguments now returns the raw slot values alongside the spliced
arguments JSON to make the reply templating possible.

* 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).

* perf(llama-cpp): checkpoint scoring at the caller-declared stable prefix

Hybrid-memory models (LFM2.5 shortconv, Qwen3.5 deltanet — where new
small models are headed) cannot rewind their state, so any prompt-cache
reuse that needs a rewind falls back to a full re-prefill. For classifier
scoring that meant every probe change re-processed the whole option-list
prompt: the server's checkpoints were placed reactively (at wherever the
previous task happened to diverge), so a checkpoint past the next
divergence was erased rather than restored — measured as intermittent
2-10s turns on prompts with a 95%+ common prefix.

The classifier now computes the probe-invariant prompt prefix once (the
byte-wise common prefix of two synthetic probe renders) and declares its
length with every Score request; the server maps it to a token boundary
and forces a KV checkpoint exactly there on each score prefill. That
checkpoint sits at or before every future divergence under the same
option list, so it always survives and always restores — repeat scoring
costs probe+candidates regardless of how the probe changes.

Also:
- prewarm reruns on every option-list registration instead of memoizing
  per list: with boundary checkpoints a redundant rewarm costs two
  probe-sized decodes, while skipping one after a slot eviction (three
  lists sharing fewer slots evict in LRU cascades) silently moves a full
  re-prefill onto the user's next turn
- new llama.cpp backend option rs_seq:N exposes bounded recurrent-state
  rollback outside speculative decoding; measured impractical for
  deltanet-scale states (65GB for 64 snapshots on Qwen3.5-4B) but cheap
  insurance for small-state models
- docs: the multi-list recipe (parallel:N + sps:0.5 — the default slot
  similarity threshold funnels distinct lists onto one slot)

Measured on the drone demo (LFM2.5-1.2B scorer, desktop CPU), steady
state: every turn 285-421ms including mode switches, vs 2.4s post-switch
and intermittent 1.3-2.9s re-prefills before.

* fix(realtime): accept legacy 'modalities' alias for output_modalities

OpenAI's Realtime *beta* used the field name `modalities`; the GA field is
`output_modalities`. 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). The GA `output_modalities` wins when
both are present, so GA clients are unaffected. Applied at the two existing
resolution points via a small modalitiesWithAlias helper.

LocalAI [bot]andEttore Di Giacinto cd65a1f645 fix(transcription): honor model-config language/translate + OpenAI language form field (#10731)
fix(transcription): honor model-config language/translate, add language form field

The /v1/audio/transcriptions endpoint read only input.Language /
input.Translate from the parsed request, and the request middleware never
populates those from a multipart upload -- nor did it read a `language`
form field. 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). Note this ensures
the language/translate flags reach the backend; whether a given engine
acts on them is up to the backend.

Closes #10655

LocalAI [bot]andEttore Di Giacinto 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.

fix(openai): stop max_tokens streaming retry loop on reasoning models

When a thinking model spends its entire max_tokens budget on the reasoning
block, the C++ autoparser clears the raw Response and delivers reasoning-only
ChatDeltas (no content, no tool calls). ComputeChoices' empty-response retry
then fires and regenerates from scratch up to maxRetries times, each
re-consuming the whole budget, instead of terminating with finish_reason
"length" (issue #9716).

Add a reachedTokenBudget helper and suppress both the built-in and
caller-driven retries when the completion count has reached the configured
max_tokens ceiling. Report finish_reason "length" instead of "stop" in the
streaming and non-streaming chat paths when the budget was exhausted.

Adds a deterministic regression test that counts backend invocations
(previously 6, now 1) plus boundary tests for the helper.

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.

Docs and tests included; opt-in via the pipeline YAML or per-session
`session.update`. Non-streaming STT backends degrade to silence-only.

* feat(realtime): explicit formally-verified state machines + parakeet streaming driver

The realtime API had several implicit state machines whose state was inferred
from scattered booleans, channels, and five separate mutexes, leaving
illegal/inconsistent states reachable. 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]andEttore Di Giacinto 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, ...).

* feat(realtime): implement input_audio_buffer.clear

Add a handler for the input_audio_buffer.clear client event that discards
a partially-captured utterance (raw PCM + buffered Opus frames) via a
unit-tested clearInputAudio helper, then acks with input_audio_buffer.cleared.

LocalAI [bot]andEttore Di Giacinto 600dafd20b feat(ced): sound-event classification backend (CED audio tagger) (#10425)
* feat(ced): sketch sound-classification backend (CED audio tagger)

Wires ced.cpp (CED, 527-class AudioSet sound-event tagger; baby cry,
footsteps, glass, alarms, dog bark) into LocalAI as a Go/purego backend.

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).

Backend code does not compile until protogen-go regenerates the pb types
and a libced.so is built (Makefile clones+builds it).

* feat(ced): REST /v1/audio/classification endpoint + capability registration

Wires the ced sound-event classification backend (AudioSet audio tagger)
end to end through the REST surface, mirroring the transcription path.

- Handler: core/http/endpoints/openai/sound_classification.go parses the
  multipart audio upload, temp-files it, resolves the model config and
  calls the SoundDetection RPC; returns {model, detections[]} JSON.
- Backend wrapper: core/backend/sound_classification.go (ModelSoundDetection)
  loads the model and normalizes the proto response into schema types.
- Schema: core/schema/sound_classification.go (SoundClassificationResult).
- gRPC layer: SoundDetection wired through the LocalAI wrapper (interface,
  Backend client, Client, embed, server, base default) so the loader-typed
  client exposes the RPC; proto regenerated via make protogen-go.
- Route: POST /v1/audio/classification (+ /audio/classification alias) with
  the audio/multipart default-model middleware in routes/openai.go.
- Capability surfaces: swagger @Tags/@Router on the handler; FLAG_SOUND_
  CLASSIFICATION usecase flag + UsecaseSoundClassification + UsecaseInfoMap +
  GuessUsecases + ModalityGroups + GetAllModelConfigUsecases; meta usecase
  option; /api/instructions audio area updated; auth RouteFeatureRegistry +
  FeatureAudioClassification (APIFeatures, default ON) + FeatureMetas; UI
  usecaseFilters, capabilities.js CAP_SOUND_CLASSIFICATION, Models.jsx filter
  + i18n; docs page features/audio-classification.md + whats-new + crosslink.

* 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.

* 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.

* 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.

* feat(ced): register sound-classification backend in gallery + CI

Mechanical backend-image registration for the ced sound-event classifier,
mirroring the parakeet-cpp Go/purego backend everywhere it is wired up.

- .github/backend-matrix.yml: add the ced build matrix, field-for-field copies
  of the parakeet-cpp entries (cpu amd64/arm64, cublas cuda 12/13 amd64,
  l4t cuda-13 arm64, l4t-jetpack cuda-12 arm64, sycl f32/f16, vulkan
  amd64/arm64, rocm hipblas, and the metal darwin entry), changing only
  backend and tag-suffix. dockerfile stays ./backend/Dockerfile.golang.
- backend/index.yaml: add the &ced meta anchor (capabilities map per platform)
  plus ced-development and the per-arch image entries, each uri/mirror
  tag-suffix matching the matrix exactly. 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.

* 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.

* feat(ced): add ced-base GGUF model gallery entries (f16 + q8_0)

The ced-base weights are now published at mudler/ced-base-gguf (Apache-2.0,
converted from mispeech/ced-base). Adds gallery/ced.yaml (backend: ced +
known_usecases: sound_classification) and two gallery/index.yaml entries
(ced-base-f16 default, ced-base-q8 smallest) with sha256-pinned files, and
removes the now-resolved TODO from backend/index.yaml.

their f16 + q8_0 gallery entries:

  ced-tiny  (5.5M, edge/Pi-class)  f16 11MB / q8_0 6MB
  ced-mini  (9.6M)                 f16 19MB / q8_0 11MB
  ced-small (22M)                  f16 42MB / q8_0 23MB

All sha256-pinned. ced-base remains the accuracy default.

All CED quantizations (tiny/mini/small/base, f16/q8_0) now live in a single
HuggingFace repo, mudler/ced-gguf, instead of per-model repos. Repoint the 8
gallery model entries' urls + file uris accordingly. sha256 and filenames are
unchanged.

* chore(ced): bump CED_VERSION to the short-clip fix

Pin the ced backend to ced.cpp 99c6ed3, which fixes a crash on any clip
shorter than target_length (~10.11s): time_pos_embed was added at its full
63-frame grid instead of being sliced to the clip's actual time grid, tripping
ggml_can_repeat in ggml_add. Surfaced by the live realtime e2e (sub-10s
windows) and gated with a short-clip parity test upstream.

* docs(ced): list ced.cpp as a LocalAI-team engine + backend-guide directive

- README.md: add ced.cpp to the "native C/C++/GGML engines developed and
  maintained by the LocalAI project" table.
- docs/content/features/backends.md: add a Sound Classification backend
  category (sound-event classification / audio tagging) listing ced.cpp.
- .agents/adding-backends.md: add a "Documenting the backend" section and two
  verification-checklist items requiring new backends to be documented in the
  backends.md category list, and in-house native engines to be added to the
  README maintained-engines table. This directive was missing.

* chore(ced): repin CED_VERSION to the v0.1.0 release commit

ced.cpp history was squashed into a single release commit (tagged v0.1.0), so
the previous pin (99c6ed3) no longer exists upstream. Pin to c04ac14, the
v0.1.0 release commit, so the backend builds against a commit that exists.

- sound_classification.go: os.Create(dst) where dst = temp dir + path.Base of
  the upload (no traversal). #nosec G304, matching the depth-anything-cpp handler.
- goced.go: reading a NUL-terminated C string from a libced-owned buffer.
  #nosec G103 (gosec) + //nolint:govet (golangci-lint's unsafeptr check), since
  the uintptr is a C-owned malloc'd buffer, not Go-GC memory.
