The vibevoice transcription e2e hangs until the go test timeout when
the HF CDN is slow: the ASR Q4_K model is >10 GB, downloadFile capped
every curl attempt at --max-time 600 (needs a sustained ~17 MB/s to
fit), and curl's --retry restarts from byte zero, so no attempt ever
makes forward progress. This killed the job twice on PR #10764 and
previously forced skipping it on release tags (#10567).
Replace the wall-clock cap with stall detection (--speed-limit 1 MiB/s
over --speed-time 120s) and resume from the bytes already on disk with
-C -, retrying from Go because curl does not re-evaluate the resume
offset on its internal retries. Resume against the HF Xet CDN was
verified by killing a transfer mid-flight and confirming the next
invocation appended (114 MB -> 235 MB, GGUF magic intact).
Also parameterize the suite timeout (BACKEND_TEST_TIMEOUT, default
30m) and raise it to 120m for the vibevoice transcription wrapper: a
10 GB download plus 25 specs does not fit in 30m even on a good day,
and the job-level GHA timeout there is already 150m.

* feat(vibevoice-cpp): true streaming TTSStream via vv_capi_tts_stream
Replaces the synth-to-tempfile TTSStream hack with a real streaming path:
binds the new vv_capi_tts_stream callback ABI via a single reusable purego
callback (CGO_ENABLED=0-safe, no runtime/cgo), copies each int16 PCM window
into the gRPC results channel after the streaming WAV header.

* test(vibevoice-cpp): real-model streaming integration test with TTFA measurement
Gated behind VIBEVOICE_IT=1, this Ginkgo spec dlopens the engine .so and
drives the exact Go->purego->C TTSStream/TTS path against the real
vibevoice-realtime-0.5B model. It measures time-to-first-audio for the
streaming path versus the batch path and asserts the streaming win:
44-byte WAV header first, >=2 PCM windows, non-silent audio, and
TTFA < total_stream. Without the env var the spec skips so CI and
normal go test are unaffected.
Measured: TTFA 2.38s vs batch deliver-time 39.96s (first audio in 5.9%
of the batch time, ~17x faster), 18 stream chunks, non-silent 24kHz PCM.

C++/ggml transcription + speaker diarization + timestamps backend. Purego
dlopens libmoss-transcribe.so (ggml statically linked) from moss-transcribe.cpp
and serves offline AudioTranscription, parsing the [start][Sxx]text[end] output
into segments with nanosecond timestamps. Adds the importer (surfaces in

and a gallery entry (default q5_k GGUF from mudler/moss-transcribe.cpp-gguf).
Local L0 smoke (go build + go test ./... = 16 pass, golangci-lint 0 issues)
passed against the real libmoss-transcribe.so. The pre-commit coverage gate

Link the f5-tts library into the crispasr backend so CrispASR's native
F5-TTS runtime (SWivid F5-TTS, 22-layer DiT flow-matching + built-in Vocos
vocoder) is compiled in. The single self-contained GGUF auto-detects as
f5-tts through the session router, so no explicit backend selector is
needed. Add the f5-tts-crispasr gallery entry (cstr/f5-tts-GGUF) and an
env-gated e2e synthesis spec.
F5-TTS is voice-cloning only and has no baked speaker: it clones from a
reference WAV plus its transcript, supplied via the voice/voice_text
options. The gallery description documents this bring-your-own-reference
requirement.
Verified e2e on the pinned engine (278fb79): the GGUF auto-detects as
f5-tts, the reference voice loads, and synthesis produces a valid 24 kHz
mono WAV.

fix(backends): pin grpcio-tools to the installed grpcio in runProtogen
runProtogen installed grpcio-tools unpinned, so the protoc it bundles
stamped backend_pb2.py with the newest Protobuf gencode (7.35.0). When a
backend caps the protobuf runtime lower -- vLLM pins protobuf to 6.33.6 --
the import-time guarantee runtime >= gencode fails:
google.protobuf.runtime_version.VersionError: Detected incompatible
Protobuf Gencode/Runtime versions ... gencode 7.35.0 runtime 6.33.6
The backend crashes on `import backend_pb2` before it can serve, which
surfaces to the user as "grpc service not ready". It was mis-reported as a
ROCm/gfx1201 failure in #10718 but is not GPU-specific and affects every
vLLM variant (and any backend that caps protobuf below the latest gencode).
Pin grpcio-tools to the grpcio version the backend already installed --
they release in lockstep -- so the generated gencode stays in step with
the protobuf runtime. Falls back to unpinned when grpcio isn't present.
Closes#10718

The OIDC verifier was built with a bare oidc.Config{ClientID: ...}, so
go-oidc applied its default of accepting RS256-signed ID tokens only. An
identity provider configured with an EC signing key (e.g. Authentik) issues
ES256-signed tokens, and the callback failed verification with:
failed to verify ID token: oidc: malformed jwt: unexpected signature
algorithm "HS256"; expected ["RS256"]
surfacing to the user as HTTP 500 "failed to fetch user info" (#10677; the
underlying cause became visible after the logging fix in #10679).
Set SupportedSigningAlgs to the standard asymmetric algorithms
(RS256/384/512, ES256/384/512, PS256/384/512, EdDSA). All are verified
against the provider's published JWKS. HS256 is intentionally excluded: it
is symmetric and would validate against the client secret, a different and
security-sensitive trust model.
Tested with a functional spec that signs an ES256 ID token and confirms it
verifies with the configured algorithms and is rejected under go-oidc's
RS256-only default (using oidc.StaticKeySet, no network).

Backend log capture into the per-model BackendLogStore (which feeds the
UI "Backend Logs" page and /api/backend-logs) was opt-in and off by
default in single mode, while worker/distributed mode force-enables it
via SetBackendLoggingEnabled(true). There was no CLI flag either, so the
only way to populate the store was the Settings UI toggle - and the page
was silently empty out of the box. Distributed "just worked"; single
mode looked broken.
Default EnableBackendLogging to true in NewApplicationConfig so single
mode matches worker mode. The store is a small in-memory ring buffer, so
the cost is negligible.
Now that the default is on, loadRuntimeSettingsFromFile's usual
"only flip false->true" merge would ignore a persisted false and revert
the UI toggle-off on every restart. There is no env var/CLI flag for
this setting, so an explicit persisted value is now authoritative in
both directions, letting the toggle-off survive a restart.

The image backends call PIL Image.save(request.dst) without a format, so
Pillow infers the encoder from the file extension. The core passes an
absolute staging path ending in .tmp (e.g. /staging/localai-output-*.tmp),
which Pillow can't map to a format, raising "unknown file extension: .tmp"
and crashing the worker right after a successful GPU inference.
Pass format="PNG" explicitly. LocalAI serves generated images as PNG
regardless of the temporary path, so this is always correct and no longer
depends on the extension of the destination the core happens to allocate.
diffusers is the reported backend (#10727); vllm-omni and tinygrad carry
the identical latent crash for any .tmp staging destination.

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.

A client that keeps polling a model whose load fails (e.g. a backend that
crashes deterministically on init) triggered a fresh backend start on
every request: request -> load -> crash in ~10s -> 500, repeat on the
next poll. Each attempt could leak GPU/CUDA state, and under
LOCALAI_SINGLE_ACTIVE_BACKEND it kept stealing the active slot from
healthy models. The existing loading-coalesce map only dedups
*concurrent* loads, so sequential polls were never covered.
Track load failures per modelID in ModelLoader. After a load fails,
refuse fresh load triggers for that model until a cooldown elapses,
returning a typed ModelLoadCooldownError that the HTTP layer maps to 503
with a Retry-After header. The cooldown grows exponentially per
consecutive failure (base, doubling, capped at 5m) and resets on a
successful load. The coalesced follower-retry of an in-flight burst
bypasses the gate, so a genuinely concurrent burst still gets its one
retry -- only new, independent triggers are refused, matching the
report's "refuse new load-triggers" wording.
Configurable via --model-load-failure-cooldown /
LOCALAI_MODEL_LOAD_FAILURE_COOLDOWN (default 10s, 0 disables), plumbed
through ApplicationConfig and applied unconditionally at startup.

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

The nvidia-l4t-cuda-13-arm64 vLLM backend left `vllm` unpinned, so the
prebuilt image drifted onto whatever aarch64 wheel was latest at build
time (0.23.x). On GB10 / DGX Spark (Grace Blackwell, unified memory),
0.23 crashes deterministically during cold model loads with an empty
"Engine core initialization failed" set and pins GPU memory until a host
reboot.
vLLM 0.24.0 carries vllm-project/vllm#45179 ("release cached device
memory under pressure on UMA GPUs during weight loading"), which the
reporter verified fixes the crash on GB10. Pin the L4T requirements to
0.24.0 to match the already-pinned cublas13 build
(requirements-cublas13-after.txt) and keep the image deterministic.
Editing this file also re-triggers the single-arch L4T image build via
the path filter, republishing the gallery image with 0.24.0 (the
single-arch matrix builds again after #10703).
