The llama.cpp C++ backend aborts generation when its gRPC context is
cancelled (grpc-server.cpp polls context->IsCancelled() in the result
loops), but Go backends served by pkg/grpc never observed context
cancellation: a disconnected client left the generation running to
completion. Add an optional Cancellable capability; the server registers
context.AfterFunc on the request/stream context (after the Locking block
so queued requests cannot abort the current owner) covering both rich
and legacy paths. dllm implements it: measured cancel latency ~10ms vs
~10s of orphaned generation, and follow-up requests no longer queue
behind cancelled ones (~220ms vs ~9s in the e2e proof).

fix(vllm): restore compatibility with vLLM >= 0.22 (get_tokenizer moved)
vLLM 0.22 moved get_tokenizer from vllm.transformers_utils.tokenizer
to vllm.tokenizers. Since the backend requirements install vllm
unpinned, freshly built/installed vllm backends currently fail to
start with ModuleNotFoundError: No module named
'vllm.transformers_utils.tokenizer' (surfacing as 'grpc service not
ready' when loading a model).
Use the same try/except version-compat import pattern already used
elsewhere in this file: try the new vllm.tokenizers location first and
fall back to the pre-0.22 path.
Tested on a DGX Spark (GB10, ARM64) with the
cuda13-nvidia-l4t-arm64-vllm backend and vllm 0.22.0: model load, chat
completions and tool calls all work with this patch applied.

subprocess_stdin() (which is sp->stdin_file), then subprocess_destroy()
fclose()s the same pointer again -> heap corruption that aborts the
backend on any base64 input_video request (the CLI --video file path is
unaffected). Vendor a one-line fix (null sp->stdin_file after fclose)
via prepare.sh's patches/ until upstream merges it.

* feat(parakeet-cpp): real segment timestamps (NeMo-faithful)
Offline: replace the single synthetic whole-clip segment with multiple
segments grouped exactly like NeMo's get_segment_offsets - a new segment
after sentence-ending punctuation ('. ? !'), each carrying start/end and
its time-window token ids. The optional model option segment_gap_threshold
(NeMo's unit: encoder FRAMES, default 0=off) adds NeMo's silence-gap split,
converted to seconds via the JSON frame_sec the engine now reports.
Per-segment words are still gated behind timestamp_granularities=["word"];
a zero-word document falls back to a single text segment.
Streaming: when libparakeet.so exposes the ABI v4 JSON entry points
(probed), drive parakeet_capi_stream_feed_json / _finalize_json and
accumulate the streamed per-word timestamps into per-utterance segments
(EOU stays the boundary), so streaming FinalResult segments now carry
start/end. Falls back to the text-only feed against an older library.
Pure-Go specs cover splitWordsIntoSegments (punctuation + gap rules, NeMo
elif order, fallback), transcriptResultFromDoc (multi-segment, token
windows, word-granularity gate), and the streaming segmenter.

Remove the obsolete LOCALAI_LEGACY_LLAMA_CPP_SPEC branches from the shared
grpc-server.cpp (stock llama-cpp and the modern fork both take the modern
path now), and narrow the one remaining gap (the fork still lacks
common_params::checkpoint_min_step) to a dedicated

head-dim 640 under HIP (cols_per_warp evaluates to 0 -> division-by-zero /
non-constant static asserts in fattn-mma-f16.cuh). That is a deep
ggml-on-ROCm kernel issue, not something a small fork patch can paper over.
Drop -gpu-rocm-hipblas-turboquant from the build matrix so turboquant still

Bump stable-diffusion.cpp from 1f9ee88 to b9254dd, the upstream commit that

Wire that field into the gosd wrapper via a new uncond_diffusion_model_path

text-to-image model with strong, accurate in-image text rendering, driven by
a Qwen3-VL-8B text encoder and real classifier-free guidance from a separate
unconditional diffusion model (the uncond_diffusion_model_path support added
in the preceding commit).
Two index entries, both built on gallery/virtual.yaml with the full config
inlined in overrides (same pattern as the other models, no dedicated template
file):
- ideogram-4-iq4nl-ggml (4-bit, ~11.6GB diffusion)
- ideogram-4-q8_0-ggml (8-bit, ~20GB diffusion)
Each bundles the diffusion + unconditional GGUF (stduhpf), the
Qwen3-VL-8B-Instruct text encoder (unsloth), and the FLUX.2 VAE (Comfy-Org
mirror, non-gated). cfg_scale is 7 to match the upstream Ideogram4 default,
since it performs real CFG unlike the guidance-distilled Flux/Z-Image models.

parakeet.cpp's batched C-API takes a single target_lang for the whole batch, so
the dispatcher only coalesces same-language requests: a request whose language
differs from the batch leader is held as a single carry-over and becomes the
leader of the next batch, never dropped and never left waiting (including on
shutdown). A new batcher test asserts no dispatched batch is ever mixed-language
and that every submitted request still receives a reply.

* feat: forward reasoning_effort to the backend so jinja models honor it

jinja-templated models whose chat template keys on reasoning_effort (gpt-oss
Harmony, LFM2.5) could not be driven by it: LFM2.5 ignores enable_thinking and
kept emitting <think>.
Forward the effective reasoning_effort to the backend as a chat_template_kwarg

metadata (gRPCPredictOpts). Add a config-level default: ModelConfig.reasoning_effort

* fix(distributed): self-heal stale 'model not loaded' routing
In distributed mode the registry can list a model as loaded on a node
while the worker has evicted it (autonomous LRU eviction, an out-of-band
unload, etc.) yet the backend process survives. The router's cached-node
check only verifies the process is alive (probeHealth), so it routes there
and inference fails with "<backend>: model not loaded" — and stays broken
until the controller restarts and rebuilds its registry.
InFlightTrackingClient now reconciles this: when a tracked inference call
returns a model-not-loaded error, it drops the stale replica row
(RemoveNodeModel) so the next request reloads the model on a healthy node
instead of routing back to the evicted one. The original error is returned
unchanged; only the registry is corrected.

IsModelNotLoaded(err) checker (status-code first, message fallback for
backends not yet migrated).
- InFlightTrackingClient.reconcile now uses grpcerrors.IsModelNotLoaded.
- Migrate the Go backends that emit this error (parakeet-cpp, cloud-proxy,

The OpenAI-compatible TTS endpoint accepts an `instructions` field, but it
was silently dropped at the HTTP->gRPC boundary: neither schema.TTSRequest
nor the gRPC TTSRequest proto carried it, so backends could only read such a
value from static YAML options (identical for every request). This blocked
per-line emotion/style and, for Qwen3-TTS VoiceDesign, limited a model config
to a single designed voice.
Plumb a generic per-request instruction string end to end, plus an optional
backend-specific params map:
- proto: add `optional string instructions` and `map<string,string> params`
to TTSRequest.
- schema: add Instructions (maps OpenAI `instructions`) and Params (LocalAI
extension) to schema.TTSRequest.
- core: thread both through ModelTTS/ModelTTSStream via a newTTSRequest helper
that attaches instructions only when non-empty (so backends can fall back to
YAML when unset); forward them from the /v1/audio/speech handler.
- qwen-tts: prefer the per-request instruction over the YAML `instruct` option
(used by both mode detection and generation) and merge per-request params.
- chatterbox: merge per-request params (coerced to float/int/bool) over YAML
options into generate() kwargs.
Fully backward compatible: empty instructions fall back to the YAML option and
backends that don't support style/voice instructions ignore the field.

The direct (non-batched) transcription path handed the original upload
path straight to the C library via parakeet_capi_transcribe_path_json.
That loader only understands 16 kHz mono WAV/PCM, so any other format
(MP3, etc.) failed with "parakeet: failed to load audio: <file>".
Only the batched path converted the input (via decodeWavMono16k ->
utils.AudioToWav). Every other audio backend (whisper, crispasr)
converts unconditionally with utils.AudioToWav before handing the file
to its engine; the parakeet-cpp fallback was the lone exception.
Extract a convertToWavMono16k helper (reused by decodeWavMono16k) that
produces a 16 kHz mono WAV in a temp dir, and run the non-batched path
through it before calling the C loader. WAV inputs already in the target
format are passed through without ffmpeg.
Add specs covering the helper (decodable copy + cleanup, and an error on
a missing input) that need neither the model, the C library, nor ffmpeg.
