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.

* fix(parakeet-cpp): reset role fields on a failed companion load
loadRoles' freeLoaded only released the C contexts it had opened; it
left ctxPtr/diarCtx/tagCtx and companions pointing at those now-freed
contexts, so a later Free() on the same instance would double-free.
Zero all four alongside the CppFree calls.
Also route AudioTranscriptionStream and AudioTranscriptionLive through
notASRError when ctxPtr is unset but a diarization or sound model is
loaded, matching AudioTranscription: both used to return the generic
model-not-loaded error instead of naming the loaded role.

* 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-
110m checkpoints on the two_speakers.wav fixture: correct A-B-A-B
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
clip: "Chicken, rooster" tops the list at score 0.91.

* fix(parakeet-cpp): cancel sound detection mid-feed, shrink the lock
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
an unlocked json.Unmarshal.

* 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.

* feat(realtime): surface live speaker and sound events
Carry the backend's closed speaker segments and sound events
(TranscriptLiveResponse fields 7/8) through LiveTranscriptionEvent
as LiveSpeakerSegment/LiveSoundEvent (nanoseconds mapped to
seconds), and forward them from the semantic_vad live path.
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
(label, score = peak, index) and the event's new optional
start/end seconds fields, omitted when unset so the existing
unary/windowed sound-detection path is unaffected.

ConversationItemInputAudioTranscriptionSegmentEvent.Start/End used

110M ASR model for speaker-attributed text, CED-Tiny and CED-Base

voice-like-sound quirk), CED as a sound classification backend, the
asr_model/diarization_model/sound_model/diarization_latency companion
options, and the realtime live speaker/sound events (event shapes,

parakeet-cpp-realtime-scene mistakenly copied cc-by-4.0 from the
existing realtime_eou_120m-v1 entry; the model card lists the NVIDIA
open model license instead. Switch to the gallery's usual spelling
for that license and keep the diarization/CED licenses called out in
the description.
Also: audio-diarization.md now says getting per-segment text needs
both an asr_model companion and include_text=true on the request, and
audio-to-text.md's option table reads "Use on" (a pairing the loader
does not enforce) instead of "Allowed on".

loadRoles let a companion option (asr_model:/diarization_model:/
sound_model:) assign into a role field the primary already occupied,
for example asr_model: on an already-ASR primary. The companion's
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
successfully loaded primary; the primary is still treated as ASR,
matching today's behavior.

* fix(parakeet-cpp): cap live scene sound score retention
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.

* fix(parakeet-cpp): merge diarization segments per speaker, harden Diarize
mergeCloseSegments only compared neighbors in the single start-sorted
segment list, so two same-speaker segments never merged once another
speaker's turn fell between them (A, B, A): the short B segment broke
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.

soundStreamDrain ran every C call under engineMu but never re-checked

tagCtx==0 check and this lock could still reach the C side with a
freed context. Re-check p.tagCtx under the lock and return
ModelNotLoaded when it was cleared, mirroring diarizeCall's own
re-check. A WAV decode failure is now reported as InvalidArgument
instead of an unwrapped/untyped error.

* test(parakeet-cpp): cover a mid-session scene feed failure
feedSlicesScene already degrades gracefully when a scene feed call
fails mid-session: it frees the broken stream and carries the ASR-only
session forward. Add a spec covering that path end to end: the scene
stream is freed exactly once, later audio slices still produce ASR
responses, and no speaker/sound events appear before or after the
failure.

* 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
index, 99.

* 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.

fix(distributed): reject wrong-model requests on the remaining modalities (#10990)
#10970 gave the four PredictOptions RPCs a model-identity check so a backend reached through a stale distributed route rejects the request instead of answering from whatever model it holds (#10952). Every other modality shares that exposure: the route is cached by host:port, a worker can recycle a stopped backend's port for another model's backend, and a liveness-only probe cannot tell a stale row from a valid one. Extends the same mechanism to the 21 remaining request messages that reach a backend through the router, using the pattern #10970 established rather than a parallel one: - proto: ModelIdentity on each modality request message. - controller: populated from ModelConfig.Model at the call site that also builds ModelOptions, so load-time and request-time values are equal by construction. - backends: one generic guard in pkg/grpc/server.go (27 Go backends), the method set in backend/python/common (36 Python backends), llama-cpp (AudioTranscription/Stream, Rerank, Score) and privacy-filter (TokenClassify). - reconcile already drops the stale row on IsModelMismatch; no change. TTSRequest and SoundGenerationRequest get a SEPARATE ModelIdentity field rather than reusing their existing `model`: FileStagingClient rewrites `model` to a worker-local path, so comparing it would reject valid requests in exactly the configuration this guards. AudioEncode/AudioDecode are deliberately left unguarded: the opus codec backend is loaded from a literal rather than a ModelConfig, so no value carries the equality guarantee the comparison depends on. The four bidirectional stream RPCs are out of scope; they bypass reconcile. Empty means skip on both sides, so an old controller, an old backend, and the bare request structs in tests/e2e-backends all keep working.

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.

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).

Assisted-by: Claude:claude-opus-4-7[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed): thread request context through backend Load + cover ctx propagation Five non-OpenAI backend helpers were silently using app.Context instead of the request context for the gRPC backend call: transcription, TTS, image generation, rerank, VAD. Effect: distributedhdr.Stamp in the router callback was a silent no-op for these paths, AND client cancellation didn't propagate to in-flight inference. Thread c.Request().Context() (or the equivalent input.Context after the request middleware has installed the correlation-ID derived context) through each helper and into ModelOptions via model.WithContext(ctx). ImageGeneration's signature gains a leading ctx parameter; in-tree callers (openai image, openai inpainting, openai inpainting_test) are updated to match. ModelEmbedding gains a leading ctx parameter for the same reason; the openai and ollama embedding handlers pass the request context through. chat_stream_workers.go defers the initial role=assistant chunk emission until the first token callback so the wrapper's lazy X-LocalAI-Node lookup against the loader runs AFTER ml.Load has stamped the per-modelID node ID; semantically identical for clients (role still arrives before any text). Regression test core/backend/ctx_propagation_test.go pins ctx propagation for all five helpers. Docs updated to enumerate the full endpoint coverage of the --expose-node-header flag.

fix(traces): cap backend trace Data to keep admin UI responsive (#9960)
* fix(traces): cap backend trace Data field so the admin UI stays responsive The previous fix (#9946) capped API trace bodies but missed backend traces, which carry the same blast radius: - LLM backend traces store the full chat messages JSON, full response, and full streaming deltas. Every agent-pool reasoning step ships the full RAG-augmented history (50-500 KiB per trace, often 100+ traces queued). - TTS / audio_transform / transcript traces embed a 30s audio snippet as base64, around 1.3 MiB per trace. Both blow the /api/backend-traces JSON past tens of MiB. The admin Traces page then keeps re-downloading and re-parsing the buffer faster than the 5s auto-refresh and stays in the loading state forever, the same symptom the API-side fix addressed. Apply two complementary caps, both honoring LOCALAI_TRACING_MAX_BODY_BYTES: Option A (safety net in core/trace): RecordBackendTrace walks the Data map recursively and replaces any string value larger than the cap with "<truncated: N bytes>". Catches anything a future producer forgets. Option B (head-preserving at the producer): - core/backend/llm.go: TruncateToBytes on messages, response, and chat_deltas content/reasoning_content so the leading content stays readable in the UI. - core/trace/audio_snippet.go: omit audio_wav_base64 when the encoded blob would exceed the cap (truncated base64 is undecodable). The quality metrics still ship and the UI's WaveformPlayer simply skips when the field is absent. TruncateToBytes is bounded to <= maxBytes so Option A leaves the producer's head-preserving output alone instead of replacing it with the bare marker. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-4-7 * fix(react-ui): expose tracing_max_body_bytes in Settings and Traces panels The setting was already plumbed through env (LOCALAI_TRACING_MAX_BODY_BYTES), CLI flag, and the runtime_settings.json GET/PUT schema, but neither the main Settings page nor the inline Traces panel offered an input for it. Admins hitting the "Traces UI stuck loading" symptom had to know to set an env var or PUT raw JSON to /api/settings to dial the cap. Add a "Max Body Bytes" row next to "Max Items" in both places. Same input type, same disabled-when-tracing-off semantics, placeholder shows the 65536 default so users see what they're inheriting. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-4-7 * test(react-ui): disambiguate Max Items locator after adding Max Body Bytes The Tracing settings panel now has two number inputs. The previous spec matched 'input[type="number"]' which became ambiguous and triggered a Playwright strict-mode violation in CI. Switch to getByPlaceholder('100') for Max Items and add a parallel spec for the new Max Body Bytes field using getByPlaceholder('65536').

* fix(whisperx): pin torch CPU variant to fix uv resolution failure
Pin torch==2.8.0+cpu so uv resolves the CPU wheel from the extra

Signed-off-by: eureka928 <meobius123@gmail.com>
* fix(whisperx): use unsafe-best-match index strategy to fix uv resolution failure
uv's default first-match strategy finds torch on PyPI before checking
the extra index, causing it to pick torch==2.8.0+cu128 instead of the
CPU variant. This makes whisperx's transitive torch dependency
unresolvable. Using unsafe-best-match lets uv consider all indexes.

* fix(whisperx): drop +cpu local version suffix to fix uv resolution failure
PEP 440 ==2.8.0 matches 2.8.0+cpu from the extra index, avoiding the

This aligns with the pattern used by all other CPU backends.

uv cannot resolve PEP 440 local version specifiers (e.g. +rocm6.4,

to the correct ROCm wheel index and --index-strategy unsafe-best-match
(set in libbackend.sh) ensures the ROCm variant is preferred.
