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.

The localai.classifier.result server event reports the full score distribution per turn. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(realtime): classifier response flow Classifier-mode responses: instead of autoregressive generation, each user turn is prefill-scored against the option list (router.ScoreClassifier prompt/candidate shapes over the Score primitive) and the winning option's canned reply and tool call are emitted through the existing response machinery. Below-threshold turns take the configured fallback (none / canned reply / generate); empty transcripts and unaddressed turns (wake word not mentioned) skip scoring entirely. The scoring probe defaults to the latest user message only — small scorers echo canned replies from prior turns back as the top option otherwise. Built for hardware that can afford prompt processing but not decode: with slot-based Score the option list stays KV-cached across turns, so a turn costs roughly one forward pass over the new words. session_update_error events now carry the validation cause instead of a generic message. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * fix(realtime): bound the VAD tick's scan window and buffer retention The VAD tick loop re-scanned the entire input buffer every 300ms and only trimmed it on zero-segment ticks or commits. Audio that keeps producing segments without a committing pause (steady noise a mic pipeline lets through, music, continuous speech) grew the buffer toward the 100MB cap with each tick rescanning all of it — O(n^2), measured at ~3.3ms of silero per buffered second: past ~90s retained, ticks run back to back and pin ~4 cores until the stream stops. Silero's recurrent state only carries a few hundred ms of context, so rescanning old audio buys nothing. Clip the slice handed to the VAD to the largest silence the commit test can need to measure (server_vad silence window or the semantic eagerness fallback) plus a warm-up margin, and rebase the returned segment times so every downstream consumer keeps whole-buffer coordinates. An open turn whose clipped window is all silence now commits (the silence outran the window) instead of being discarded as no-speech. Independently, retain at most 90s of raw buffer, rebasing the live-feed and EOU cursors on trim — this also bounds the previously unbounded VAD-error path. Turn boundaries are otherwise unchanged: no forced commits, no new coordinator states. pipeline.turn_detection.vad_window_sec can widen the scan window; values below the automatic floor are ignored. The tick body is extracted into vadTick so specs can drive turn detection synchronously (same shape as classifySoundWindow); the babble reproduction that pinned 4 cores now plateaus under 10% of one core.

The YAML threads: knob has been dead config: a tiny VAD model could never opt down from the global pool size. SetDefaults already fills an unset per-model value from the app config, which is the intended precedence; resolve threads through a helper that honors it (explicit threads: 0 still means unset). Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * chore(gallery): single-thread the silero VAD Silero is a ~2MB recurrent model with no exploitable graph parallelism: measured per-call latency is identical at 1 and 10 ORT threads, while every extra pool thread just spin-waits between the realtime loop's frequent tiny inferences. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * docs(realtime): classifier mode, VAD scan window, threads precedence Document the realtime classifier mode (options, threshold guidance, wake-word address gate, empty-transcript handling), the VAD scan window and 90s buffer retention (pipeline.turn_detection.vad_window_sec), the per-model threads precedence, and the M3 classifier note in the realtime state-machine design doc. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * perf(llama-cpp): score all candidates in one batched decode One scoring call is now a single SERVER_TASK_TYPE_SCORE task: the slot decodes the shared prefix (prompt + longest common candidate token prefix) once, then forks one sequence per candidate off it (metadata-only for the unified KV cache, copy-on-write for recurrent state) and decodes every candidate's unique tail in one llama_decode. Previously each candidate was its own task that restored the boundary checkpoint and re-decoded its full tail sequentially, paying per-candidate task and decode overhead. The context reserves SERVER_SCORE_FORK_SEQS extra sequence ids (and recurrent-state cells) beyond the parallel slots via the new common_params::n_seq_score_forks. Forking requires the unified KV cache (already this backend's default) since per-sequence streams would shrink n_ctx_seq; an explicit kv_unified:false disables forking and Score calls that need it fail cleanly. Candidates beyond the fork/output budget decode in successive chunks. Wire contract and scores are unchanged: per-token logprobs are stitched from the shared region and the forked tails. Verified bitwise deterministic call-to-call and independent of candidate order (no cross-fork leakage via equal-length candidate swap); ranking matches the per-candidate implementation on the drone battery (winner softmax 0.99996 vs 0.99997), and >16-candidate chunking, prefix-of-another and empty candidates all pass. Measured on a desktop CPU: warm /api/score calls 0.52s -> 0.23s; warm realtime classifier turns 196-303ms. The 9-candidate drone turn decodes ~17 unique tail tokens in one batch instead of nine sequential ~220ms checkpoint-restore tasks. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * fix(realtime): gate scoring capacity by model usecase Reserve llama.cpp scoring slots only for models that explicitly declare the score usecase, while allowing score to coexist with chat and completion. Reject incompatible unified-KV settings and classifier activation on models without scoring capacity. Propagate application defaults when resolving realtime and preload pipeline stages so unset thread counts are resolved consistently without overriding explicit model settings. Assisted-by: Codex:gpt-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * fix(ci): honor APT mirrors in the prebuilt llama-cpp compile step The builder-prebuilt path installs gcc-14 with apt directly and ignored the APT_MIRROR/APT_PORTS_MIRROR build args the from-source path already honors, so an ubuntu mirror outage broke every arm64 backend build. Pass the args into the stage and run apt-mirror.sh (already in the build context via COPY . /LocalAI) before the apt step. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(realtime): classifier argument slots via constrained completion Hybrid classify-then-complete: a classifier option's canned tool call can declare typed argument slots (number | enum | string, with defaults and prompt hints) referenced as "{{name}}" in the arguments template. When the option wins, the slots are filled by a short grammar-constrained completion that continues the exact scoring prompt — rendered by the same cached ScoreClassifier, so the llama.cpp prompt cache is already warm — with the chosen route JSON re-opened at the first slot field. A GBNF grammar pins the field skeleton and frees only the values; temperature 0, a couple dozen tokens at most (~300ms on a desktop CPU for two slots). Slot declarations and hints ride the option descriptions in the shared system prompt, informing scoring and the fill alike at no per-turn token cost. The localai.classifier.result event carries the final arguments and a fill_latency_ms. On inference failure the slots' defaults apply; a slot without a default fails the response (or falls through with fallback.mode: generate). Slot filling requires completion alongside score in the scoring model's known_usecases. Verified end-to-end on the Pi drone demo: "fly forward three meters" in distance mode classifies forward and infers {"distance": 3, "units": "meters"} in ~310ms, and the drone flies exactly 3 units. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * 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. Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * fix(realtime): harden classifier slot completion Reserve context for constrained slot filling, size completions from their encoded output, and encode enum grammar literals as valid JSON. Reject empty enum values and cover the failure modes with regression tests. Assisted-by: Codex:gpt-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(realtime): prewarm the classifier scoring prompt on registration Swapping a session's classifier option list (a voice-switched command mode, for instance) made the next turns pay a full re-prefill of the new option-list prompt — measured 2.4s vs 0.3s warm on a desktop CPU, and worse: on hybrid-memory models like LFM2.5, whose state cannot be partially rewound (llama.cpp can only restore checkpoints), *every* probe change re-prefilled from scratch whenever the last checkpoint missed the probe boundary, so even same-list turns intermittently cost full prefills. Registering an option list (pipeline seed or session.update) now fires a best-effort background prewarm: two throwaway scores with distinct probes. The first prefills the new option-list prompt; the second, diverging exactly where per-turn probe text starts, plants the backend's rewind point (KV checkpoint) at the stable-prefix boundary that every real turn reuses. The prewarm hides behind the canned mode-switch reply — by the time it finishes speaking, the cache is warm. Idempotent per option set, detached from the registering request's lifetime. Measured on the drone demo (LFM2.5-1.2B, desktop CPU): first turn after a mode switch 2374ms -> 340ms; intermittent same-list full prefills (1.3-2.1s) all -> under 0.5s. For clients that swap lists frequently, options: [parallel:2] on the scoring model additionally keeps one slot per list via prefix-similarity routing (+26MB RSS, unified KV). Assisted-by: Claude:claude-fable-5 Signed-off-by: Richard Palethorpe <io@richiejp.com> * perf(llama-cpp): checkpoint scoring at the caller-declared stable prefix Hybrid-memory models (LFM2.5 shortconv, Qwen3.5 deltanet — where new small models are headed) cannot rewind their state, so any prompt-cache reuse that needs a rewind falls back to a full re-prefill. For classifier scoring that meant every probe change re-processed the whole option-list prompt: the server's checkpoints were placed reactively (at wherever the previous task happened to diverge), so a checkpoint past the next divergence was erased rather than restored — measured as intermittent 2-10s turns on prompts with a 95%+ common prefix. The classifier now computes the probe-invariant prompt prefix once (the byte-wise common prefix of two synthetic probe renders) and declares its length with every Score request; the server maps it to a token boundary and forces a KV checkpoint exactly there on each score prefill. That checkpoint sits at or before every future divergence under the same option list, so it always survives and always restores — repeat scoring costs probe+candidates regardless of how the probe changes. 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.

mudler's LocalAI [bot]	0f7186f214	feat(ui): replace the stacked operations bar with a one-line strip and an Activity page (#11163) ... * feat(ui): record finished gallery operations in a bounded history ring The operations panel drops an operation the moment it succeeds, so a user who steps away cannot tell whether an install finished, failed or was never started. OpCache now keeps the last 50 terminal operations, recorded from the point where an op leaves the cache. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(ui): pin the history ring's dedupe, outcome order and start stamp Review of the history ring found four gaps. The dedupe guard and the bounded seen set were unreachable through the exported API and so had no coverage; an in-package spec file now drives opHistory directly. The outcome switch claimed an ordering was load bearing that nothing pinned, so an errored op that never reached Processed now has a spec. Two behaviour fixes come with it. StartedAt was the zero time for ops recovered from the store or replicated from a peer, since neither path stamps a start time, which would have rendered as a two-millennia duration; it now falls back to the finish time. Reusing a cache key with a fresh job ID orphaned the previous stamp, so Set and SetBackend now drop it. The comment on the outcome switch described a state the code cannot be in: CancelOperation sets Cancelled and Processed synchronously before the handler removes the entry, so status.Cancelled already covers the cancel endpoint. The !Processed clause stays for the dismiss endpoint firing on an in-flight op, and the comments now say so. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): record operations that end on a peer replica The NATS end event is the only signal a replica gets for an install another replica ran. Record from applyEnd too, deduped by job ID so the originating replica does not record its own broadcast twice. Three start-stamp defects in the same path go with it. applyEnd now drops the stamp unconditionally, since recordTerminal only cleans up on the path where it found a cache key and an end event can overtake the local Set. applyStart drops the stamp of the job whose cache key it replaces, which a peer-driven retry previously stranded. And recordTerminal reads the stamp once instead of testing Exists and then reading, so a concurrent record for the same job can no longer delete the stamp between the two and let the zero time overwrite the finish-time fallback, which the Activity page would render as a two-millennia run. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ui): do not guess the outcome of a peer operation with no local status A replica that restarts mid-operation hydrates its OpCache keys from PostgreSQL, but gallery statuses are in-memory only and come back empty. The end broadcast then landed on recordTerminal's nil-status branch, which reads a missing status as queued-and-removed and filed a successful install as cancelled. That reading is right locally and wrong on the peer path, where a missing status means the outcome was never held here. recordTerminal now takes the source of the terminal event and records nothing when the peer path finds no status, restoring what the replica did before the end event started recording. The local path is unchanged. Also move the ApplyEndForTest seam to the conventional export_test.go, and stop the dedupe spec from claiming to guard the ring's seen set: the local delete removes the status keys, so the broadcast that follows returns before reaching it. An in-package spec that calls recordTerminal twice does the pinning.

The live /api/operations payload is unchanged so the one second poll stays small. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): expose operation history through OperationsContext Fetched on demand and when the live list shrinks, never on the one second poll interval. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ui): detect operation departure by identity and ignore committing ops in the ETA gate Refetching history on a shrinking live count missed a completion that coincided with a start, which is the common case during a batch install. Track the live job IDs instead, so any departure triggers the refetch regardless of how the count moved. An operation that has finished downloading stays live at currentBytes == totalBytes for the whole commit and install phase and can never produce an estimate, so counting it in the all-or-nothing gate blanked every other operation's time remaining for as long as it lasted. Only operations still moving bytes get a vote. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ui): let only downloading operations gate the time remaining estimate Verifying pins an operation flat below its total for the whole sha256 pass: the AfterDownload hook reports completedBytes plus the finished file against a total summed over every file, then hashes synchronously without emitting progress. Files download sequentially, so a 15 shard model enters that window 14 times, and a byte comparison cannot see it because the counter is genuinely below the total throughout. Gating on phase closes resolving, verifying, committing and persisting in one predicate, so a quiet neighbour no longer blanks every other operation's estimate for minutes at a time. The byte clauses stay: a producer can report downloading with bytes already at the total.

The strip now shows one operation, failure first, with a counter linking to Activity. The close button hides the strip and no longer cancels an install. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ui): keep the operations strip from widening the page and from muting a failure A long install error made the strip report a 1600px minimum width, which sized main-content to fit and gave every page under it a horizontal scrollbar. Inline-size containment plus shrinkable detail and bytes cells keep it inside the viewport. Hiding is no longer able to swallow the hidden job's own failure, a completed removal or staging says so instead of claiming an install, a cancelling operation renders as cancelling, and the live region no longer covers the per-second percentage. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ui): shrink main-content instead of containing the strip, and expose progress min-width on .main-content is what actually lets a long install error shrink, and unlike inline-size containment it has no browser support floor and no latent collapse if the strip ever lands in a shrink-to-fit context. It matches what .app-layout-chat .main-content already does, and it clears pre-existing horizontal overflow on narrow viewports as a side effect. The progress track is now a labelled progressbar, so assistive tech can read the value on demand rather than losing it to the aria-hidden that stopped the live region re-announcing every poll. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): add the live operation card for the Activity page Carries the detail the one-line strip has to drop: phase, bytes, the per-node breakdown for cluster installs, and a labelled Cancel button. Cancelling is destructive, so it gets a labelled button rather than a glyph. A cancelling operation drops its progress bar and its time estimate, the same call the strip makes: a percentage still climbing under "Cancelling" reads as the cancel not having taken. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ui): give the operation card a verb, live node disclosure and its per-node detail The card carried no verb, so an install, a removal and a staging op rendered as spinner plus name plus kind tag and were indistinguishable. It now runs the same verb and icon chain as the one-line strip, which is what stops the page that is meant to carry more detail from carrying less. The auto-expand default was evaluated once at mount. An operation is listed as soon as it is admitted but its nodes are filled in only when the fan-out starts reporting, so a card mounted at creation latched on the empty list and stayed collapsed. The default is a live expression now, and state holds only an explicit choice. Also: an optional onRetry gates a Retry button, so the page can own the install reconstruction without the card ever showing a control with nothing behind it; the disclosure moved above the region it controls and gained aria-controls; the toggle is gated at more than one node so the count is never "1 nodes"; an unmapped node status is passed through instead of being relabelled "Queued"; error text is clamped with the full string in the title; and file_name plus the per-node progress bar are rendered again, reviving three CSS rules that had gone dead along with the detail they styled. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): add the Activity page Live operations, unacknowledged failures and the record of what finished, at /app/activity in the Operate console. Cancelling an install now lives here behind a labelled button rather than on the strip, and a failed install can be retried: the retry dismisses the failure first so it still reaches the record, then reissues the model, backend or node-scoped backend install. The sidebar Operate entry carries the operation count. The console rail is only rendered on an Operate route and can be collapsed, so a badge there could vanish while operations were still running. Two follow-ups from review fold in here: a failed removal or staging job no longer reports a failed install on either the card or the strip, and the card's error text can shrink so one unbroken token cannot widen the card. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ui): dismiss operations by job, and stop the Activity page contradicting itself Dismissing resolved the job by display id, but /api/operations strips the "node:<nodeID>:" prefix before emitting, so a local install and a node-scoped install of one backend arrive as two jobs sharing one id. Dismissing by id retired whichever came first. That defeated the guarantee retry was built around: with the wrong job dismissed, the reinstall overwrote the acted-on failure's opcache entry in place, bypassing recordTerminal, while an unrelated failure vanished from Needs attention. dismissFailedOp, the card's dismiss control and the strip now all pass the jobID, which is what the endpoint takes. A filter matching nothing rendered the "nothing has ever run" empty state while the header counted the records the filter had hidden. The empty state is now gated on the All chip and a narrowed view gets its own message plus a way back; the header counts the instance rather than the chip, so selecting Backends no longer reports "Nothing running" over running model installs. Also: the summary drops a zero clause instead of rendering "0 needs attention" on the happy path and pluralises both counts; a record duration is floored at "< 1s" and rejected above a day, so a zero-value start stamp cannot render a span of millennia and a zero span cannot render "installed in" with nothing after it; a deletion cancelled mid-flight reports the cancellation rather than claiming it was removed; and the retry variant comment names the fix instead of calling the gap closed. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs: document the Activity page and the operations history endpoints Adds an Activity page under Operations covering the one-line operations strip, the /app/activity sections and filters, per-operation cancel, retry and dismiss, the in-memory 50-entry record, and the sidebar count. Documents GET and DELETE /api/operations/history, and fills the gap in the admin-only endpoint list, which also omitted the pre-existing POST /api/operations/:jobID/dismiss. Corrects the distributed-mode install-watching section: the per-node breakdown now lives on the Activity page rather than on the strip, which rolls a fan-out up into a single phrase. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs: correct nine details in the Activity page documentation The operations strip never renders a file name: its detail line is the error, the node roll-up, the target node, the phase or the queued note. Drops the stale clause in the distributed-mode section, where the per-node bullet is now the only place a file name is described. Scopes the phase vocabulary to artifact-backed gallery models, since a plain GGUF install emits no phase. Corrects the per-node list: the toggle exists for any fan-out of two or more workers and the four-node threshold only governs whether it starts open, while the N nodes tag needs more than one node. Notes that a cancelled operation can sit in the live section reading Cancelling, that cluster staging never reaches the record, and that Clear history appears only when the record has something in it. Names the operations response envelope, with a JSON example, so callers do not index a bare array, and stops describing the icon-only dismiss control as a labelled button. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs: drop the unreachable Cancelling state and scope the byte claims An operation can only report isCancelled while it is unprocessed, but every writer of Cancelled sets Processed in the same breath, on the peer path as much as the local one, and the cache evicts cancelled entries before the handler sees them. The state cannot reach the page, so the live section is described again as running or queued operations. Byte counts come from the artifact bridge alone, the same producer as the phase, so a plain GGUF install, a removal and a backend install report none. Scopes both to artifact-backed gallery models and leaves the verb, the name and the percentage as what every operation shows. A worker backend install reports its bytes through fields the operations payload does not carry, so the distributed section now describes the percentage and the node roll-up, with per-file counts pointed at the per-node detail. Also: staging jobs carry no error, so they never reach Needs attention and Retry never had a staging case to exclude; an install that involves workers is no longer called node-scoped, which this page uses for node-targeted installs; and the record timestamps carry nanoseconds. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs: state only the verb and the name as unconditional on the strip The percentage is as conditional as the bytes were: it renders only for a running operation that has reported progress, so a queued operation, a failed one and a removal never carry it. A removal in particular sits at progress zero for its whole visible life, since the delete path reports none and its completion is filtered out. Both the strip and the card paragraphs now lead with what always shows and list the rest as conditions. The Cluster chip matches on a node list that finished operations do not carry, so a fan-out install leaves the chip once it reaches the record. Scoped that claim to the live sections. Two more of the same shape, found by re-reading each clause alone: the strip also appears for a failure, which is not running, and the four-second hold only applies when nothing replaces the operation that just finished. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ui): stop reporting a cancelled install as installed, and make queued real Three defects that all trace to one root cause: `isCancelled: true` is unreachable from /api/operations. Every writer of Cancelled=true also sets Processed=true, the handler skips Processed && Cancelled, and OpCache.GetStatus evicts a cancelled op before the handler iterates it. Cancelling the last running operation put a green "Installed model X" on the strip for four seconds: the completion hold was guarded by `!previous.isCancelled`, which is dead. A cancellation deletes the operation server side, so the strip sees exactly what it sees on a completion, and nothing in the payload separates the two. The signal now comes from the side that issued the cancel: the operations context remembers the job IDs it cancelled (pruned after a minute) and the strip asks before it holds anything. A cancelled operation goes as soon as it stops; the record already reports it as cancelled. isQueued was set only when the gallery status was missing, but markQueued publishes a "queued" status at admission, so a queued op has a status for its whole queued life and the state was unreachable outside a microsecond window. Every operation waiting behind a running install rendered as "Installing model X" with a spinner. The queued phase is now the signal, via an exported PhaseQueued and a nil-safe OpStatus.IsQueued() next to the writer. With those two fixed, the Cancelling state has no way to be entered: cancelling is instantaneous from the API's point of view. Its branches, CSS, locale key and the isCancelled field itself are removed rather than left for a future reader to assume they work.

Every later writer (the worker's first write, the progress ticks, the failure path) leaves the field at its zero value, so the flag survived only the queued window, and both surfaces test isQueued first. The reachable consequence is that a failed removal reported itself as a failed install, which is exactly the shape the Activity page offers Retry for, and Retry installs: pressing it on a removal that failed re-downloaded the model. A running delete also rendered as "Installing model X" with a spinner, and a successful one as "Installed model X". Carry Deletion forward the way Nodes already is. A job is a delete or an install for its whole life; an unset flag means "no new information", not "this is an install". Pinned by Go specs on both the service and /api/operations: the existing Playwright specs were green only because they stubbed a payload the server could not emit. Also restore the operation's own status message on the Activity card. Phases and byte counters exist only on the managed-artifact path, so a legacy files: gallery model and every backend install rendered a sub-row with nothing in it but the verb. The strip stays terse on purpose. And give the strip's name a min-width floor: overflow: hidden zeroes its automatic minimum, so a long error squeezed the name down to "mod…" and the identity of the thing that broke was the first thing lost. primaryOperation is made module-private: its comment claimed the Activity page selected the same operation, but that page shows all of them, partitioned into failed and running, and never imported it. Assisted-by: Claude Code:Opus 5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(activity): read the operations record from PostgreSQL The Activity page's record of finished installs and removals was a 50-entry in-memory ring per frontend replica. In distributed mode that is the wrong place for it: each replica keeps its own copy, a replica added by a scale-out or a rolling deploy starts empty and never backfills, and "Clear history" clears only the replica that served the request, so the record reappears on the next poll routed elsewhere. The data is already in gallery_operations. Read it from there. GalleryStore gains ListTerminal and ClearTerminal, sharing a lifted terminalStatuses set with CleanOld so there is one definition of "finished". ListTerminal orders by updated_at, when the operation reached its terminal status, because the record reports what finished and when. OpCache.History and ClearHistory dispatch on whether a store is wired, so the HTTP handlers and the OpRecord JSON shape are unchanged and the page needed no change. A failed store read falls back to the local ring rather than blanking the page, and ClearHistory empties the ring as well so a database blip cannot resurrect a record the admin just cleared. The name derivation in recordTerminal is lifted into operationDisplayName and used by both paths, so the ring and the store cannot name the same operation differently. Also fixes a pre-existing bug the store path made visible: the backend channel hardcoded op_type "backend_install" even for a removal, while the model channel derives model_install/model_delete from op.Delete. Both channels carry the same ManagementOp, whose Delete field the backend handler already branches on, so the backend channel now derives backend_delete the same way.

A cancelled install was recorded as a failure. The cancel handler persists "cancelled" synchronously, then the handler goroutine unwinds with the context error and Start hands that to updateError unconditionally, which overwrote the row with "failed: context canceled". The page rendered a cancelled install as a red failure card offering Retry, with a raw context error as the reason. Fixed in GalleryStore rather than in Start, because an operation finishes once and the paths that retire one are not mutually exclusive: UpdateStatus now refuses to rewrite a row that already reached a terminal status. That also pins updated_at to when the operation really finished, which is the key the record is ordered by, and Create's upsert now freezes the same columns so a worker dequeuing an operation the admin cancelled while it was queued cannot reopen it as pending. ClearHistory returned nothing, so a failed delete logged a warning while the handler still answered 200. The admin watched the record clear and come back on the next fetch with nothing said about why. It now returns the error, the DELETE handler answers 500, and the store is cleared before the local ring so a failure leaves the fallback record intact rather than faking an empty one. Hydrate is the only reader that decides from op_type whether an operation is a removal, and it tested for "model_delete" exactly, so the backend_delete added in the previous commit hydrated as an install: a replica restarting during a backend removal rendered "Installing backend X". Both discriminations now go through IsDeleteOpType/IsBackendOpType so a fifth op_type cannot silently read as an install in whichever consumer was missed. Also: the backend channel now persists Cancellable as !op.Delete, matching the model channel; IsBackend falls back to the op_type prefix, since is_backend_op is only written by UpsertCacheKey and the rows needing the name fallback were reporting backend operations as models; and an unrecognized terminal status is logged rather than quietly filed as a success, which is what the comment already claimed.

It froze "failed" alongside "completed" and "cancelled", and the stale reaper writes "failed" onto operations that are still going to run. The gallery worker is a single goroutine consuming both channels serially, so an operation queued behind a large download sits in "pending" with nothing bumping updated_at, and ReapStaleOperations gives up on it after 30 minutes. That used to be self-healing: the worker dequeued it, Create reset the row to "pending", and the operation reported its real outcome. With the freeze the row stayed "failed" forever while the install ran and succeeded underneath it: a red failure card offering Retry for a model that is installed, omitted from ListActive so no replica hydrates it, and no longer deduped cluster-wide by FindDuplicate. Freeze on ("completed", "cancelled") instead. That is all the cancelled-install fix ever needed, and it leaves a failure correctable by what actually happened. The set is separate from terminalStatuses, which ListTerminal, ClearTerminal and CleanOld all still want in full, because the two mean different things: a failure can be superseded by a real outcome, a completion or a cancellation is the real outcome. UpdateStatus now writes the error column unconditionally, so a corrected outcome drops the previous attempt's reason rather than being recorded as completed while still carrying "stale operation reaped" as its error. Also adds the route-level spec for the 500 branch of DELETE /api/operations/history, and trims a comment that credited the persisted cancellable column with more than it survives long enough to do. Assisted-by: Claude Code:claude-opus-5 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(activity): offer Cancel in the phase that can honour it The cancellable flag was set at both ends of an operation's life and was wrong at both, in opposite directions. A queued operation is cancellable whatever it is. EnqueueModelOp and EnqueueBackendOp select on the operation context, so cancelling one that is still waiting releases the delivery goroutine and abandonQueued retires it: the worker never sees it, nothing is downloaded, nothing is deleted. markQueued nevertheless wrote Cancellable: !deletion, so a queued removal reported cancellable: false and the UI hid the Cancel button in the one window where pressing it both works and leaves no trace. A removal queued behind a large install was stuck there until the install finished. A running removal is not cancellable at all. DeleteModel and DeleteBackend take no context, and modelHandler only checks the operation context after the call returns, so a "cancelled" verdict would land after the model was already gone. Both handlers nevertheless wrote Cancellable: true unconditionally at entry, ahead of the op.Delete branch, offering a Cancel button the server cannot honour. So the queued phase is more cancellable than the running phase, which is the reverse of the usual shape. markQueued now reports true unconditionally, and the handler-entry writes report !op.Delete. Both sites carry a comment saying why, because reading either one alone suggests the other is a bug. GalleryStore.Create keeps !op.Delete: it runs at dequeue, so its value already describes the running phase. Its comment now says so. Specs cover queued removal, queued install, running removal and running install through the handlers, plus the queued-removal case through /api/operations where the flag is consumed, plus the behaviour the whole asymmetry rests on: a removal cancelled while queued never reaches the worker and deletes nothing. No existing spec asserted the old values.

One line, ellipsised, full text in the title, matching what the error string already does. The spec that found it runs with no route stubbing at all. Every other spec here stubs /api/operations, which is how a payload the server cannot emit (isDeletion true on a live operation) stayed green through a full review while the UI rendered a removal as an install. It is skipped unless LOCALAI_REAL_BINARY is set, so CI is unaffected.

mudler's LocalAI [bot]	878a0d00a1	fix(distributed): reaper reaps live backends, ghost model stubs, in_flight leak, sidecar staging runaway (#11142) ... * fix(distributed): stop the probe reaper from orphaning busy backends The reconciler's liveness probe is a 1s gRPC HealthCheck, and a single failed probe deleted the model's node_models row. A backend that is merely busy cannot answer it: single-threaded Python backends (video and avatar generation) block for minutes inside one request, so the reaper was deleting registry rows for backends that were alive and mid-request. The model then vanished from the nodes page while it was still generating, and because the row was gone the in-flight decrement had nothing to decrement ("DecrementInFlight: no matching row or already zero"). Every subsequent request re-routed and re-staged the full model from scratch. Two guards: - Replicas with in-flight requests are excluded in SQL. A row that is actively serving is proof of life, and the running request is exactly what stops the backend from answering the probe. - Idle replicas must miss three CONSECUTIVE probes before removal, so a transient blip cannot orphan a live replica. A successful probe resets the streak. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * fix(distributed): drop the local model stub when its last replica goes In distributed mode every routed model leaves an in-process stub in the frontend's ModelLoader, and DistributedModelStore.Range reports local stubs UNION the registry rows. Every registry removal path deletes only the DB row, so the stub outlived the replica and the model was reported as loaded forever. That is the "loaded on the home page, absent from every node" ghost: /system reads the union and still sees the stub, while /api/nodes/models reads the registry and correctly sees nothing. It never self-healed, and both frontend replicas showed it independently. The replica-removed chokepoint could not fix this as it stood, because it held a SINGLE hook that the prefix cache already owned, and it was registered only when the prefix cache was enabled. Registering a second listener would have silently displaced the first. - Turn replicaRemovedHook into a list (AddReplicaRemovedHook), so independent subsystems can each register without displacing others. - Add NewLocalStubInvalidator, which drops the local stub once no healthy replica of the model remains anywhere in the cluster, and wire it unconditionally in startup. The stub is kept while another node still serves the model: the frontend is right to consider it loaded, and each request re-routes through SmartRouter to pick a live replica anyway.

The sender walked the model directory with no filter, so it staged those sidecars too, and the receiver duly wrote a sidecar for each sidecar. Every staging pass multiplied the tree: config.json -> config.json.sha256 -> config.json.sha256.sha256 -> ... One LongCat snapshot had grown to 498 files, 466 of them chained, up to 29 levels deep, and the staged file count climbed on every pass. This inflates each transfer and grows disk without bound on both ends. Skip hash sidecars in stageDirectory, and mirror the skip in countStageableFiles so the progress bar still reaches 100%. The check is "a sidecar sitting next to a real file" rather than a blanket suffix ban, so a model that genuinely ships a .sha256 payload with no corresponding base file is still transferred. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * fix(distributed): classify the liveness probe instead of gating on in_flight The previous commit excluded replicas with in-flight requests from the probe reaper. That was the wrong guard, and could invert the bug it fixed. in_flight has no decrement guarantee: track() balances its increment with a defer, but a frontend killed mid-request never runs it, and the load-time reservation is released only when the first inference completes. Nothing resets a leaked counter. Gating the reaper on it therefore meant a leaked counter would shield a genuinely dead replica from ever being reaped. Nor was patience alone a fix: three misses at the default interval is ~90s of silence, while the generation that triggered this blocks for 15+ minutes. The real conflation was in the probe itself. A gRPC HealthCheck against the backend's serving port measures "is it idle enough to answer", not "does the process exist", and probeLoadedModels discarded the error that tells them apart. Because the gRPC client is lazy, the status code is decisive: - DeadlineExceeded: transport fine, nothing serviced the RPC. Busy. - Unavailable: nothing is listening. Gone. ModelProber now returns a ProbeOutcome, and only ProbeUnreachable counts toward the reap threshold. ProbeBusy clears the streak: it is evidence of life. A blackholed network reads as busy too, deliberately, since whole-node failure is the health monitor's job. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * feat(distributed): reconcile replicas against worker-reported processes Probing a backend's own serving port cannot distinguish "busy" from "gone" without inferring it from an error code. The worker can answer directly: it spawned the process, holds the handle, and its reply is not blocked by whatever that backend is doing. Adds a models.running request-reply subject. The worker answers out of its in-memory process table, reporting each live process as (modelID, replicaIndex, address) — the supervisor's process keys are `modelID#replica`, which is isomorphic to a NodeModel row, so the reconciler can diff the two directly. reconcileNodeProcesses runs before the port probe and reaps rows for models the worker is not running. Models the worker vouches for get updated_at bumped, which takes them out of the port prober's stale set entirely: that is what keeps a backend deep in a long generation away from the probe in the first place, rather than relying on classifying its silence after the fact. A worker that does not answer is skipped, not assumed empty. A messaging failure says nothing about the processes, and assuming the worst would delete a node's rows on a transient NATS blip; the port probe stays as the fallback for those nodes. Rows younger than probeStaleAfter are ignored so a freshly created row is never judged against a process table that has not caught up. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-5 [Claude Code] * fix(distributed): stop in_flight leaking and pin replicas against eviction A leaked in_flight counter is not cosmetic. FindLRUModel, FindGlobalLRUModelWithZeroInFlight and the router's eviction query all require in_flight = 0, so a replica whose counter never came back is pinned and its VRAM is unreclaimable for the lifetime of the process. Two halves. The source: routing reserves in_flight = 1 at load time so a freshly loaded replica is not evicted out from under the request that caused the load. That reservation was released ONLY by the first inference completing, so a route torn down before any inference ran (client disconnect, handler error, failure between load and the backend call) stranded it. newRouteResult now wires the reservation to a sync.Once fired by whichever comes first, the first inference or route teardown, and replaces three copies of the old wiring. The backstop: a sweeper for counters leaked by paths that cannot run a defer at all, such as a frontend killed mid-request. Identifying a leak by elapsed time alone is unsafe. IncrementInFlight stamps last_used at request START and nothing moves it while the request runs, so a long generation is indistinguishable from a leak by age, and resetting there would expose a serving model to eviction. The probe supplies the missing bit: a backend that answers a health check promptly is not inside a request, because that is precisely what a busy one cannot do. Requiring the row to also be idle for 30 minutes covers backends that serve in parallel and can answer while working, since those keep last_used fresh through each new increment. Two existing tests asserted the old behaviour ("No decrement on Release"). That assertion was the leak, so both now pin the release instead.

mudler's LocalAI [bot]	5d57c08c6e	feat(distributed): cache staged-artifact hashes and publish the model load lifecycle (#11121) ... feat(distributed): cache staged-artifact hashes and publish load lifecycle Every load request re-hashed every staged artifact on the controller (probeExisting and the upload path both re-read the full file), which for a large multi-file model on NAS-backed storage is minutes of pure re-reading per request even when nothing changed - observed as ~9 minutes of "Upload skipped (file already exists with matching hash)" before every avatar generation. Cache the local hash in the same .sha256 sidecar the worker-side transfer server already maintains, invalidated whenever the sidecar is older than the file. The whole staging+loading phase was also invisible: the NodeModel row was only written after LoadModel succeeded, so /api/nodes and the UI showed nothing while a cold load spent 10+ minutes staging - indistinguishable from nothing happening. Publish the lifecycle instead: "staging" as soon as the node is chosen, "loading" when the checkpoint load starts, and the existing "loaded" on success, with the row removed on any failure so a dead load does not leave a phantom replica. The early row also reserves the replica slot against concurrent schedulers. The nodes view already renders non-loaded states on model chips; style "staging" like "loading". Audited every state-filtered registry/router query: eviction, routing, reconciler and idle-model queries all filter state='loaded' explicitly, so the new transitional rows are visible to observability surfaces but inert to scheduling decisions (except slot occupancy, intentionally).

mudler's LocalAI [bot]	6584db992f	fix(nodes): never schedule a model onto a node that cannot store it (#11054) ... * fix(nodes): never schedule a model onto a node that cannot store it A worker whose models filesystem was 100% full kept advertising `status: healthy`, stayed a scheduling candidate, was picked to host a 70 GB video model, accepted the staging request, transferred ~17 GB and only then failed: staging .../whisper-large-v3/model.fp32-00001-of-00002.safetensors: upload to node b7bacbf4-... failed with status 500: writing file: /models/longcat-video-avatar-1.5/...: no space left on device The node was at 937G/937G/0-avail. Total elapsed before the truth surfaced: 16 minutes, for a decision that could never have succeeded. The worker health signal only ever proved liveness. `/readyz` (WorkerReadiness/NATSReadiness) checks the NATS link; `status: healthy` in the registry is driven by heartbeat recency. Node capacity carried VRAM and RAM but no disk figure at all, and the router compared model size against VRAM only — nothing anywhere looked at free space on the filesystem that staging actually writes to. Report it, then use it: - Workers now measure the filesystem backing their MODELS directory (not `/` -- staged weights land in the models path, and that mount is very often separate) and report `total_disk`/`available_disk` on registration and on every heartbeat. Free disk moves faster than VRAM under staging traffic, so the per-heartbeat refresh matters. - The SmartRouter drops nodes that cannot store the model before it picks one. The requirement comes from `modelPayloadBytes` -- the same local paths `stageModelFiles` uploads, already computed for the size-derived load budget -- plus a 5% / 1 GiB margin, rather than a fixed percentage of the node's disk. A percentage threshold would take a small-but-usable node out of rotation for models it could hold, and on a homogeneous cluster would strand every node at once. - When no node fits, scheduling fails immediately with an error naming the requirement and each node's free space, instead of picking one and discovering it mid-transfer. Two deliberate non-changes. Low disk does not mark a node `unhealthy`: the check is per model, so a node too small for one model stays a valid target for smaller ones. And `total_disk == 0` means "does not report disk" (pre-upgrade worker, or a failed stat), not "full" -- such nodes pass through untouched so a rolling upgrade never empties the candidate pool. A genuinely full node is distinguishable: non-zero total, zero available. Registry read failures are logged and scheduling continues unfiltered; a database hiccup must not wedge a cluster. Free space is surfaced on the node detail page next to VRAM, since the incident's signature was a node that looked entirely healthy.

A scheduler-side veto with no escape hatch is a liability: our size estimate can be wrong (deduplicating or compressing filesystems, a backend that fetches its own weights rather than loading the staged copy), and an operator who hits that has no way out but a downgrade. Add one knob with two surfaces that share a single source of truth: - `--distributed-disk-headroom-check` / `LOCALAI_DISTRIBUTED_DISK_HEADROOM_CHECK` (default true), following the `--distributed-prefix-cache` pattern for a default-on distributed feature. - `distributed_disk_headroom_check` in the runtime-settings registry, so it can be flipped without a restart from `POST /api/settings` and from Settings -> Distributed in the WebUI. Both write `DistributedConfig.DiskHeadroomDisabled`, and the SmartRouter reads that member LIVE on every scheduling decision through a closure over the application config rather than a value snapshotted at construction. Env/CLI sets the boot value, the runtime setting overrides it live, last write wins, and there is exactly one member to read. Snapshotting would have made the runtime toggle a no-op until restart. Disabled means WARN, not SKIP. Selection goes back to ignoring free disk -- byte for byte the pre-check behaviour -- but the check still runs, and when it would have rejected every node it says so, naming the knob that suppressed it. Going quiet when switched off would reproduce the exact condition that made the original incident expensive: a cluster doing something that could not work and saying nothing. Disabling is also logged once at startup. Warning only on the total-rejection case keeps it actionable rather than chatty on a heterogeneous cluster. Also fixes a false positive in the check itself: shared-models mode (LOCALAI_DISTRIBUTED_SHARED_MODELS) stages nothing at all -- every node already mounts this models directory at this path -- so demanding the full checkpoint size of free space per node would have rejected a cluster that needs no new bytes. The check is skipped there entirely.

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

A backend reinstall could poison every subsequent model load on a worker node until the worker process was restarted. gallery.InstallBackend (and gallery.UpgradeBackend) replace a backend by renaming the live directory to `<name>.install-backup`, moving the staged directory into place, then deleting the backup.

Python backends import torch lazily inside LoadModel, so such a survivor still answers HealthCheck and keeps its gRPC port. It looks healthy and only detonates when a model is actually loaded through it. The install paths already stop running processes before replacing the directory (installBackend's force branch, upgradeBackend, backend.delete), but they resolve them by name. That bookkeeping reaps nothing whenever the recorded name no longer resolves into the install's identity set: a legacy entry with an empty backendName, backendIdentity degraded to name-only matching after a ListSystemBackends failure, or an earlier reinstall having already rewritten the metadata.json that carries the alias. Any of those leaves a live process whose directory is about to be unlinked, and nothing downstream notices, because the reuse gate checks liveness and name -- and the name is precisely what does not change across a reinstall. Record the directory each supervised process runs out of, plus that directory's identity at spawn time, and compare with os.SameFile before reusing the process. This needs none of the name bookkeeping to have been correct. Both reuse gates are covered: processMatchesBackend (the install fast path) and startBackend's own already-running branch, which now force-stops such a survivor so the fresh spawn chdirs into the newly installed directory. Processes with no recorded directory are accepted, so a rollout does not restart every running backend once. This matters more with #11024 pending: making GPU backends visible to the upgrade checker will have AutoUpgradeBackends fan upgrades out to worker nodes at scale, and every one of those is a reinstall. Left as is, a rare manual-upgrade footgun becomes a fleet-wide one.

mudler's LocalAI [bot]	01fca9c9b2	fix(distributed): scale the remote model-load deadline with checkpoint size (#11030) ... The gRPC deadline for the remote LoadModel call was a fixed 5m. It starts only after the backend install and file staging have completed, so it covers the worker's checkpoint read and pipeline init alone - work whose duration is proportional to the bytes on disk. A fixed value is therefore a model-size cliff, not a timeout. Measured in production: a 70 GB video checkpoint (longcat-video-avatar-1.5) on an NVIDIA Jetson Thor worker failed reproducibly with "rpc error: code = DeadlineExceeded" after 953.5s of wall clock. Backend install plus staging consumed ~11m, then LoadModel got its 5m and expired. The load never had a chance, and the operator saw only a generic DeadlineExceeded with no hint that a config value was the cause. Raising the constant does not fix this. It moves the cliff to the next larger model - the cluster has to support 600 GB checkpoints - and it makes a genuinely wedged SMALL model hang for the whole inflated duration before anyone notices, which is a real regression in failure latency. So derive the budget from the checkpoint size instead: budget = 5m + 20s/GiB, capped at 6h 2 GiB -> 5m40s, 70 GiB -> 28m20s, 600 GiB -> 3h25m. The per-GiB rate is deliberately pessimistic (~54 MB/s of weight read) because the errors are not symmetric: too long costs only failure latency on a load that was going to fail anyway, too short is a guaranteed false failure on a healthy load. The size is measured from the frontend's local model files, over the same path set stageModelFiles uploads. When those files are not present locally - a backend handed a bare HuggingFace repo id fetches its own weights on the worker - there is nothing to measure and the budget stays at today's 5m. An explicit LOCALAI_NATS_MODEL_LOAD_TIMEOUT still wins outright, in both directions: a shorter override is honoured, so an operator who wants fast failure is not silently extended by the heuristic. The cold-load hold needed widening to match. It extends on staging progress, but LoadModel reports none, so once the last byte lands the hold expires a stall window later and would cancel a load still well inside its own budget. scheduleAndLoad now extends the hold by the load budget plus the staging margin as it enters the load phase; ModelLoadCeilingFor stays the hold's starting budget rather than its maximum. Finally, a deadline that does expire now names the budget, the checkpoint size it was derived from, and the knob that overrides it, instead of surfacing a bare "context deadline exceeded".

mudler's LocalAI [bot]	a4a181d2f7	fix(distributed): count staging verification as progress, not as a stall (#11026) ... Testing the progress-based cold-load deadline on the live cluster surfaced a false positive. The stall window observed UPLOAD bytes only, but the staging path has a phase that does real work while moving zero upload bytes: the resumable-upload verify phase. When a shard is already present on the worker from an earlier attempt, the frontend HEADs it, hashes the local copy to confirm it matches, and skips the transfer. Staging a 70 GB model with 56 GB already staged: 17:27:34 INFO Upload skipped (file already exists with matching hash) ... 17:28:20 INFO Upload skipped (file already exists with matching hash) ... 17:29:07 INFO Upload skipped (file already exists with matching hash) ... ... six-plus consecutive minutes, no bytes uploaded at all ~45s per skipped ~4 GB shard. That is correct and desirable - it is what makes resume work - but it was indistinguishable from a stall. At 45s per shard it sits inside the 5m window, so the run in flight was fine; the problem is the 600 GB scale this machinery exists to enable, where one shard can plausibly hash for longer than the window. The guard would then fire during verification of a transfer that is working perfectly. Verified mechanism: probeExisting() HEADs the worker and then calls downloader.CalculateSHA(). The staging progress callback is only consulted inside doUpload(), which the skip path never reaches, so observeLoadProgress was called zero times for the whole verify phase. Verification exposed a second, worse bug in the same path: CalculateSHA consults no context at all. An expired cold load kept hashing to completion, compared the hashes, and returned success - reporting a file as staged on a dead load. The failure only surfaced on the NEXT file, whose HEAD died immediately. That is exactly the shape of the red test here, which fails on shard 3. Fix: hash in 1 MiB chunks via hashFileWithActivity(), ticking the cold-load deadline per chunk and checking ctx per chunk. A successful HEAD also counts, since a 200 with a content hash proves the worker is serving right now. Counting hash progress does not make a dead transfer look alive: hashing is bounded, terminating work proportional to file size, in probeExisting it runs only after a HEAD proved the worker was up, and the 24h absolute cap still bounds the whole hold. The alternative of simply widening the window was rejected - it would reintroduce the size cliff this work removes.

mudler's LocalAI [bot]	b700a78ae4	fix(distributed): make the cold-load hold scale with progress, not wall-clock (#11019) ... A 70 GB video checkpoint (longcat-video-avatar-1.5) could not be loaded on a distributed cluster. The request failed with HTTP 500 after 1499.98s - exactly the 25m00s cold-load ceiling - while staging was demonstrably healthy: 26 of 57 files and 39 GB transferred at a sustained ~26 MB/s, zero errors, no stalls. It was not wedged, it was killed by a timer. ModelLoadCeilingFor covers node selection, backend install, file staging and the remote LoadModel. Install and load carry their own budgets; staging was covered only by a FIXED 5-minute margin. But staging time is bytes over bandwidth, not a constant: 70 GB at 26 MB/s needs ~45m against a 25m ceiling, so the failure is deterministic for any sufficiently large model rather than a flake. Simply raising the constant moves the cliff to the next model size - the deployment target here is checkpoints of 600 GB and beyond. The ceiling's real purpose is that "a wedged worker can never pin the lock indefinitely". Progress, not elapsed time, is what distinguishes a wedged worker from a large one. The hold is now a deadline that extends whenever the transfer reports bytes and expires a 5-minute stall window after they stop: - A large model transferring fine continues, for hours if needed. - A worker that died mid-transfer still fails within the stall window. Progress is observed at byte level on the transfer itself, via the existing staging progress callback. Per-file completion would be too coarse - a single 600 GB shard would be indistinguishable from a stall for hours. The observation point is back-pressured by the socket, so it reflects the network rather than local disk reads. Observation is coarsened to one timer touch per stall/20 so the per-read callback stays cheap. The base budget (unchanged, and still derived from the install and load timeouts) continues to cover the steps that report no progress, so LOCALAI_NATS_MODEL_LOAD_TIMEOUT keeps working exactly as before. An absolute cap of 24h bounds the hold even while progress keeps arriving, so a peer trickling bytes forever cannot pin the advisory lock; 600 GB at the measured 26 MB/s is ~6.5h, so the cap sits far above any legitimate transfer. Also fixes the incoherent layering the same error exposed: the resumable upload carried a 1h retry budget nested inside the 25m ceiling, so the inner budget was unreachable and the message still blamed it ("failed after 1 attempts within 1h0m0s budget") while the 25m parent was the actual killer. The upload now adopts the caller's deadline when there is one, and applies its fixed budget only when nothing above bounded it - which also stops a fixed 1h from reintroducing the size cliff under the now-extendable parent. This is the successor to #10968, where a hardcoded 5-minute LoadModel gRPC timeout was replaced by this derived ceiling. Fixing the inner timeout exposed the outer ceiling as the new binding constraint.

mudler's LocalAI [bot]	0eb8a1188d	fix(worker): give the worker a real health endpoint and a mode-aware HEALTHCHECK (#10999) ... fix(worker): give the worker a real health endpoint (#10987) The image bakes in a single HEALTHCHECK that curls http://localhost:8080/readyz, but the same image also runs `local-ai worker`, which serves HTTP on the gRPC base port minus one and never binds 8080. Every worker container was therefore permanently `unhealthy` (43 consecutive failures observed on a production node), which is worse than having no healthcheck: a genuinely broken worker and a perfectly good one both report `unhealthy`, so the signal carries no information and orchestration that keys on it misbehaves. The worker already served /readyz on that port via the file-transfer server, but as a constant 200 — it only proved the listener was bound, which is precisely the failure mode at issue. Readiness now tracks the live NATS connection: all of a worker's actual work (backend lifecycle events, inference dispatch, file staging) arrives over NATS, so a worker whose link is dead is up and useless. Registration is already implied, since the server only starts after registration succeeds. This reports something the controller cannot already see. The node registry's status/last_heartbeat is fed by an HTTP heartbeat to the frontend, a different network path from NATS — a worker can keep heartbeating while its NATS connection is dead and still look healthy in the registry. /healthz stays a constant 200: liveness must not follow readiness, or a NATS blip becomes a cluster-wide restart storm. The HEALTHCHECK is now a script that derives its endpoint from the mode the container is actually running plus the env vars that configure the bind address, so a frontend moved off 8080 with LOCALAI_ADDRESS (broken the same way) and a worker on a non-default base port are both probed correctly. Modes with no HTTP surface (agent-worker, one-shot commands) report healthy rather than false-unhealthy. HEALTHCHECK_ENDPOINT remains as an explicit override, so the workaround shipped in docker-compose.distributed.yaml keeps working; both overrides in that file are now unnecessary and have been removed. Also fixes the latent --start-period gap. Since #10949 a frontend's startup preload materializes HuggingFace artifacts before the HTTP server binds (31 GB observed on a live cluster), so a healthy replica can legitimately fail probes for a long time. --start-period is Docker's knob for exactly this: failures inside it leave the container `starting` instead of burning retries, and it ends early on the first success, so a generous 60m costs a fast-starting container nothing. --timeout drops from 10m to 10s — it is a per-probe deadline, and a localhost curl that has not answered in 10s is itself the fault being detected.

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

Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): key meta pin recall on the installed name and detach resolved entries Six review findings on the meta-entry install path. Pin recall was keyed on the gallery entry name while applyModel writes the record under the install name (req.Name when supplied), so a meta installed under a custom name with a pin lost that pin on reinstall and was silently re-resolved onto a different variant, possibly swapping its backend. Compute the install name with applyModel's own precedence before the recall. ResolveMetaModel returned a shallow struct copy, so the resolved entry's Overrides aliased the gallery entry's map and the install path's in-place mergo merge wrote the caller's request into the shared catalog. Detach Overrides, ConfigFile, AdditionalFiles, URLs and Tags. Not exploitable today only because this path re-unmarshals the gallery per call, which is a property nobody should have to rely on. Also: overlay the meta's name onto the persisted config for meta installs so the gallery file no longer records the variant's name; move the pinned-VRAM warning below the variant validation so a pin naming a nonexistent entry does not warn about VRAM before failing for an unrelated reason; and stop seeding config.URLs in the config_file branch, which duplicated every declared URL. Add seven network-free specs driving InstallModelFromGallery with a meta entry: variant payload wins over the meta's legacy url fallback, the resolution record round-trips to disk, a pin is recorded and honored on reinstall including under a custom install name, and the resolved entry does not alias the gallery's maps. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): deep-copy meta overrides and make two specs functional ResolveMetaModel detached the resolved entry's Overrides and ConfigFile with maps.Clone, which only copies the top level. Gallery overrides are nested in practice (parameters.model is near-universal) and the install path merges the caller's request with mergo.WithOverride, which recurses into nested maps and overwrites them in place, so the gallery entry's own inner maps were still reachable and still got rewritten by the last caller to install. Copy both maps all the way down instead, recursing through the container shapes a YAML decoder produces. ConfigFile is not mutated on the install path today, but it carries the same kind of nested payload and leaving it shallowly cloned would invite the bug back. Also fix two specs that passed whether or not their target fix was present: - "does not write the caller's overrides back into the gallery entry" re-read the catalog from disk, which re-unmarshals fresh structs and so cannot observe in-memory aliasing. It now asserts against the in-memory gallery entry and drives the real mergo merge. - "round-trips the resolution record to disk under the meta's name" asserted a name that is already correct in the config_file branch. It now drives the url branch via a file:// fixture, where the meta-name overlay actually applies. Both were verified red by reverting their fix.

The capability check is the only compensating control for a typo there. Candidate matching is a case-sensitive exact comparison against SystemState.DetectedCapability(), so an unknown value never matches and falls through silently instead of erroring. The vocabulary therefore mirrors the raw return set of getSystemCapabilities(), which notably excludes "cpu": that is a fallback key inside Capability(capMap) on the meta backend path, never a reported capability. A CPU-only host reports "default". These pass vacuously until the pilot meta entry lands; the guard is intentionally in place before the thing it guards. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(gallery): close coverage gaps in the meta entry lint The ordering invariant grouped candidates by capability and asserted floors descend within a group. A candidate with an EMPTY capability matches every host, so it does not belong in its own group: it dominates every later candidate whose floor is at or above its own, across capability groups. Track a running minimum floor over the unconditional candidates instead, which subsumes the old same-group check for the empty capability. Every spec skipped non-meta entries, so with zero meta entries in the index all five bodies were no-ops. Aligning GalleryModel.IsMeta() with GalleryBackend.IsMeta(), whose semantics are deliberately opposite, would have made all of them pass while checking nothing. Extract each invariant into a helper over a slice of entries returning the violations it finds, and cover those helpers with synthetic fixtures so the logic stays tested at zero meta entries. The index-driven specs are now a thin application of already proven logic. Also assert the index parses non-empty, report every violation in one run rather than aborting on the first, and parse the index once for the suite.

Computing these needs network access, so it happens nightly rather than at install time. An authored min_vram is never modified: a human who measured a real load knows more than a pre-download estimate does. The index is rewritten via yaml.Node rather than a document round-trip. A full round-trip reflows all ~26k lines of gallery/index.yaml, which would bury the computed values and make the nightly PR unreviewable. The rewrite touches only the three derived keys, so authored styling survives and a run that computes nothing leaves the file untouched. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ci): keep the gallery denormalize diff reviewable and self-healing The nightly denormalization job edits YAML nodes instead of round-tripping structs so its PR stays small enough for a human to review, but the write path undid that: yaml.Marshal re-encoded the node tree at yaml.v3's default 4-space indent and dropped the leading document marker, reflowing roughly 6000 lines around the handful of real changes. Encode through yaml.NewEncoder at the index's authored 2-space indent and restore the header. A write that changes three fields now changes three lines. Stale inferred_min_vram values were also never cleared. Both skip paths (an authored min_vram is present, or the candidate is the last resort) returned before touching the field, so a candidate that gained a floor or became the last resort after a reorder kept an inferred value that EffectiveMinVRAM reported as a real constraint, failing the meta lint with no way for the job to self-heal. Clear the field before both skips. The workflow discarded a whole night's work on any single failure: the program exits 1 when a candidate cannot be estimated, which aborted the job before the PR step, so one unreachable candidate blocked every other refresh indefinitely. Capture the status, open the PR with what was computed, mark the PR body as partial, and fail the run afterwards so the problem still surfaces. Also preserve the index's existing file mode instead of forcing 0644, and drop the redundant //go:build ignore tag, since Go already skips dot directories and the sibling modelslist.go carries no tag.

It resolves to the Q8_0 build on hosts with at least 6GiB of VRAM and to the Q4_K_M build everywhere else, installing either payload under the stable name nanbeige4.1-3b. The entry carries a url equal to its final candidate's url. LocalAI releases that predate candidates support parse the index non-strictly and drop the key silently, so without that url they would list the entry and install nothing. A regression spec parses the index the way those releases do and asserts every meta entry stays installable for them. Also teaches core/schema/gallery-model.schema.json about candidates. The schema sets additionalProperties: false at the top level, so an author following CONTRIBUTING.md and adding the yaml-language-server comment would otherwise get a validation error on this entry. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): make candidate entries complete, installable entries Reworks hardware-resolved gallery variants after a design pivot. There is no longer a separate "meta" entry kind. A gallery entry is a normal, complete entry that may additionally carry candidates:, a list of hardware-gated upgrades over itself, and the entry is itself the last-resort candidate. The previous design relied on a bare url: as the fallback for LocalAI releases that predate candidates support. That fallback is empty in practice: none of the 80 gallery/*.yaml files carry a top-level files:, and 1216 of 1281 index entries carry their payload in the index entry itself, so a url alone yields a config template with nothing to download. Since every released LocalAI reads gallery/index.yaml live from master, merging a payload-less entry would have shown every existing user a model that installs to a broken state. Making the entry its own base candidate removes the problem at the root: old clients drop the candidates key and install the entry exactly as they do today. Resolution order is now explicit pin, then capability plus VRAM over the declared upgrades, then the entry itself. The entry ALWAYS installs: when its own min_vram or capability is unmet the installer warns and installs it anyway, because there is nothing below it and refusing would make the gallery behave worse the newer the client is. A pin naming the entry's own name is valid and is how an operator declines an upgrade. IsMeta() becomes HasCandidates(), ResolveMetaModel becomes ResolveVariant, and the persisted meta_name record key becomes entry_name. GalleryBackend.IsMeta() is a separate concept and is untouched. The lint drops the three rules the pivot makes wrong (url equality with the final candidate, no inline payload, unconstrained final candidate) and gains one: the entry's own floor must sit strictly below every candidate's, since a base that outranks a candidate makes that candidate unreachable. The pilot entry is now the existing nanbeige4.1-3b-q4, which gains a 2GiB floor of its own and a single 6GiB upgrade to nanbeige4.1-3b-q8, replacing the separate nanbeige4.1-3b entry added in d0d441bb4. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): select model variants by hardware fit, not authored order Gallery entries could already carry a list of alternatives, but selection was an authored, ordered, first-match policy: every candidate declared a `capability` string and the VRAM floors had to descend in a hand-tuned order. That pushed hardware knowledge onto whoever edits the gallery and made ordering load-bearing, so a reordered list silently changed what users installed. None of it was necessary. SystemState.IsBackendCompatible already derives hardware support from a backend name alone: it knows MLX and metal are Darwin-only, CUDA is NVIDIA-only, ROCm AMD-only, SYCL Intel-only. Selection can read that instead of asking authors to restate it. Authoring is now just a list of names: - name: qwen3.6-27b min_memory: 4GiB variants: - model: qwen3.6-27b-mlx-8bit - model: qwen3.6-27b-gguf-q8 min_memory: 28GiB and all the intelligence moved into the selector. Given a host it drops the variants whose backend cannot run here, drops those whose known memory requirement exceeds what the host has, and takes the LARGEST of what is left, because a bigger footprint is a higher quality quantization of the same model. A variant of unknown size is kept, since nothing proves it does not fit, but it ranks last so a proven fit always beats a guess. An explicit pin still wins outright, and if nothing survives the entry installs its own payload: the base always installs, this never refuses. Available memory is VRAM when a GPU was detected and system RAM otherwise, read through xsysinfo so a cgroup limit is honored and a container gets its own limit rather than the node's RAM. Capability disappears entirely, from the types, the schema and the lint. VRAM and RAM collapse into one `min_memory`, because a model's footprint is roughly the same wherever it lives and one figure is compared against whichever applies. The lint rules about ordering, the capability vocabulary and floor relationships are deleted with the hazards they described; what remains is that every variant names an entry that exists and does not itself declare variants, plus that any memory figure actually parses.

That figure was written into the index by a nightly job, which made the gallery carry a derived value that could drift from the entry it was derived from. Derive it at install time instead. pkg/vram already sizes a model without downloading it, and the gallery UI already uses it: a remote GGUF header range-fetch, then an HTTP HEAD for the content length, then any declared size:. It caches its results, so reuse it rather than writing a second probing path. A probe failure must never fail an install, so an unprobeable variant is treated as unknown: it survives the memory filter, because nothing proves it does not fit, and it ranks last, so a known-good fit always beats a guess. If every probe fails, selection still terminates on the base entry. The probe is injected through ResolveEnv rather than called directly, for the same reason the backend compatibility check is: specs pin an exact size, or an exact failure, without reaching the network. With that in place three things are dead weight and go: - The nightly job and the fields it populated. Variant.Backend was redundant because the backend is resolved live from the referenced entry during selection, and Quantization was display-only that nothing read. - min_memory on the base entry. The base always installs and its floor could only warn, so it could not change any outcome. - The lint rules and schema entries for both. min_memory on individual variants stays, as the override for when the probed size is wrong. An authored figure now suppresses the probe entirely rather than merely outranking it, so it costs no round trip.

Selection already worked at install time, but nothing could see what an entry offered or ask for a specific build, so the feature was undrivable. Listing: `GET /api/models` now reports `variants` and `auto_variant` for the entries that declare variants. Each variant carries its resolved backend, its measured size and whether it fits this host. `auto_variant` is what installing without a choice would pick right now. The new gallery.DescribeVariants runs the same variantOptions + SelectVariant pass the installer runs, so the reported default cannot drift from what installing actually does, and HostResolveEnv is extracted so both derive the host and share pkg/vram's probe cache from one place. Performance: an entry that declares no variants returns early without touching the probe, so the ~1280 ordinary entries cost exactly what they cost before. Selection: `variant` is accepted on POST /models/apply, as a query param on POST /api/models/install/:id, on the gallery apply file/string request, as `local-ai models install --variant`, and as a parameter on the install_model MCP tool (both the httpapi and inproc clients). Empty means auto-select. An unknown variant name now fails the install naming what was requested. This closes a real hole: an entry declaring no variants short-circuits before selection runs, so a requested variant was previously dropped silently and the install reported success. startup.InstallModels ends in a variadic model list, so install options could not be appended to it; InstallModelsWithOptions is added alongside and InstallModels delegates to it. No caller signature changed. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): drop the redundant variant min_memory field Variant.MinMemory was an authored override for when the live probe misreads a variant's footprint. It duplicated an existing field: probeEntryMemory already passes the entry's declared size: into EstimateModelMultiContext, whose cascade prefers that declared size over its own guesswork. Correcting size: on the referenced entry fixes the figure for every consumer rather than only for variant selection, so min_memory shadowed the right answer. A variant is now nothing but a name. Its effective size is exactly the probe result, and an unknown stays unknown: it survives the filter and ranks last. EffectiveMemory loses its error return along with the field. The authored string was the only thing that could fail to parse, so the error had no remaining source and was propagating dead nil-checks through SelectVariant, DescribeVariants and the pin warning. Selection behaviour is unchanged. The specs covering probe-derived sizing, ranking, filtering, the unknown-size path, pin recall, entry/variant metadata split and deep-copy isolation all survive; the three install specs that needed a definite size now declare it through the referenced entry's own size:, which exercises the documented escape hatch directly. gallery/index.yaml is untouched: no entry ever carried the key. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): rank the entry's own build against its variants Variant selection pulled the declaring entry's own payload, the base, out of the candidate set and consulted it only once every declared variant had been rejected. Two real failures followed. A variant whose size the probe cannot determine deliberately survives the memory filter, because nothing proves it does not fit. As the only survivor it then won outright on any host, however small: a 2GiB machine installed an unmeasured variant in preference to the 4GiB build the entry itself ships, with no warning. 241 of the 1280 current index entries carry no files and no size, which is exactly that shape. "Largest wins" also broke whenever the base was the largest. An author writing a Q8 entry that offers a Q4 downgrade for small hosts, a natural shape that nothing in the lint, schema or docs discourages, had the Q4 installed on every large host instead. Make the base an ordinary participant. It is still exempt from both filters, so selection always terminates on something installable, but it is now ranked against the variants: a proven fit first and largest, then the base, then any variant whose size nothing could measure. Both failures disappear together. The base is probed for its size accordingly, which it was not before, because an unsized base would lose every contest to an unmeasurable variant. FellBackToBase is kept but narrowed to "no declared variant survived", rather than "the base was chosen", since the base now also wins on merit and that is not worth warning about. A recalled variant pin also became a permanent install failure. A pin the caller supplies on this request must stay fatal, but one recalled from ._gallery_<name>.yaml can be invalidated by any later gallery edit, and failing on it turned one rename into a model that could never be reinstalled or upgraded again short of deleting a dotfile the user has never heard of. A stale recalled pin is now dropped with a warning naming it, and selection runs as if it had never been recorded. Also drop the last textual reference to two abandoned designs from the DetectedCapability comment, correct the documented variants JSON example, which showed a memory_bytes of 0 that omitempty makes impossible, and remove an em dash from the install skill.

Apple Silicon satisfies the first branch and fails the premise: arm64 macs report the metal capability unconditionally, without probing anything, while TotalAvailableVRAM has no discrete VRAM pool to find and returns zero. The budget therefore came out as zero on every Mac. Zero drops every variant carrying a known size, so the base build was installed on all of them however much memory the machine had. The feature was inert on the platform, and silently: falling back to the base is a legitimate outcome, so nothing looked wrong. Take VRAM only when it is actually a number, and fall back to RAM otherwise. On a unified-memory host RAM is not an approximation of the budget, it is the budget, since the GPU shares it. A discrete GPU whose VRAM could not be read also lands on RAM, which overstates what the card holds but understates nothing the host has; the previous zero understated both. An unreadable RAM figure still yields zero and still installs the base, so a genuinely unknown host is not talked into a larger download. This is what turned tests-apple red: "installs a fitting variant's payload under the entry's own name" asserts on selection, and the runner resolved to the base because its budget was zero. The added specs pin the branch directly rather than relying on a macOS runner to notice again. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): add a model variant picker to the models gallery PR #10943 shipped the server side: a gallery entry may declare `variants:`, `GET /api/models` attaches `variants` and `auto_variant` to declaring entries, and `POST /api/models/install/:id` accepts a `variant` query parameter. Nothing in the UI consumed any of it, so the feature was not reachable from the browser. This wires it up. modelsApi.install takes an optional second argument and appends an encoded `?variant=` only when one is given, so every existing call site keeps sending exactly the request it sent before. On the models table, an entry that declares variants gets a split button. The primary Install still installs the auto-selected build, because auto is the default and the point of the feature; the chevron opens a menu for a deliberate override. It follows the Backends.jsx precedent: one shared Popover re-anchored per row, rendering .action-menu items, which brings Escape, outside-click and focus return along with it. An entry that declares no variants renders exactly as it did before. A variant that does not fit is dimmed but stays selectable, since the server honors an explicit choice with a warning rather than refusing it. memory_bytes is omitempty on the wire, so an absent key means the size is unknown and never zero. A single helper guards both the menu and the detail row, because formatBytes would otherwise render a falsy value as "0 B", which reads as "needs nothing". The expanded detail row gains a Variants section listing each build's backend, size, whether it fits, which is the entry's own build, and which one auto-selection would pick, built from the existing DetailRow helper and .badge classes. Eight Playwright specs cover the picker, including that plain Install sends no variant parameter and that choosing one sends it. One pre-existing assertion was scoped with .first(): the Variants section legitimately adds more llama-cpp badges to the detail row, which tripped strict mode. UI line coverage 49.42% -> 49.36% against a 40.0 baseline and 0.8pp tolerance; branch coverage rose 72.04% -> 72.66%. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): describe model variants from a companion endpoint Variant description probes each referenced entry's weight files over the network: an HTTP HEAD plus a ranged GET, serial, five seconds per probe with no aggregate deadline. Running it inline in GET /api/models made one listing cost (entries x variants) round trips. The Manage page fetches with items=9999, so at 200 declaring entries that is ~1000 serial probes, minutes of a blocked handler and gigabytes of range traffic for a single page load. Only one entry declares variants today, but the feature exists so that many will. Follow the precedent already set for VRAM estimates. The listing now reports only has_variants, a length check on loaded metadata that touches nothing, and GET /api/models/variants/:id returns the description for one entry, mirroring estimate/:id in route shape, auth and error handling. DescribeVariants itself is unchanged; only its caller moved. The picker fetches lazily at the two points where a user asks to see variants, opening the split-button menu and expanding the detail row, and caches per entry for the page session. An entry declaring no variants issues no request at all. A spec counts real HTTP hits on the weight files, so it goes red if description becomes reachable from the listing path again through any caller. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): filter the model gallery to entries that declare variants The gallery is heading towards showing parent entries and hiding the individual builds they reference, so a user sees one row per model rather than six quantizations of it. Adoption is a single entry today, so defaulting to that would leave a one-row gallery. This ships the migration-phase inverse instead: the default is untouched, and a toggle narrows the list to only the entries that declare variants. It previews the end state and changes nothing until someone asks for it. The filter is server-side, next to term/tag/backend/capability and above the pagination arithmetic. The listing paginates at 9 items, so narrowing on the client would leave totalPages and availableModels describing the unfiltered set and hand the user empty pages. It selects on HasVariants(), which reads already-loaded metadata, so it issues no variant probes. The parameter is named has_variants after the listing field it selects on, and is compared against "true" like the other boolean query params (all_users, save_checkpoint), so has_variants=false reads as absent. With it omitted the response is byte-for-byte what it was before. The control is the shared Toggle component, matching the fitsFilter toggle already on this page: same wrapper class, same icon and label shape, same localStorage persistence. Unlike fitsFilter it resets to page 1 on change, which a server-side filter has to do. Stacking the toggle with a tag or backend filter easily yields nothing while one entry declares variants, so the empty state now names the variants filter as the cause rather than leaving a user to conclude the gallery is broken.

Full-description areas now render through renderMarkdown (marked + DOMPurify), matching how Backends.jsx and the Manage detail panels already handle the same content: - Models.jsx expanded detail row - VoiceLibrary.jsx voice detail header The truncated one-line previews must not render block Markdown: a leading "#" would become an <h1> and wreck the row height and rhythm. They get a new stripMarkdown() helper instead, which reduces Markdown to a single line of readable plain text. It is used for the cell text and for the title tooltip, since a tooltip full of "[](url)" is no better than a cell full of it: - Models.jsx gallery table description cell - Manage.jsx model and backend resource-row descriptions stripMarkdown walks marked's lexer output rather than running regexes over the source, so what it strips is by construction what renderMarkdown would have rendered, and it needs no new dependency. Output lands in JSX text nodes, so React escapes it; no new dangerouslySetInnerHTML beyond the two full-description sites, both of which run DOMPurify. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ui): strip Markdown from the backends table description cell Commit b35d630cf fixed this for gallery models but left the Backends admin page with the same asymmetry: its detail panel renders the description through renderMarkdown, while the collapsed table row dumped the raw gallery string into both the cell body and the title tooltip. That is user-visible. 40 of the 949 entries in backend/index.yaml carry Markdown - insightface uses inline code backticks, others use lists and links - and backend descriptions also contain embedded newlines, so the one-line cell showed literal syntax. The cell now runs stripMarkdown over the description once and uses the result for the text and the title, matching Models.jsx and the ResourceRowDesc component in Manage.jsx. The '-' placeholder is preserved, and now also fires when a description reduces to nothing after stripping. The detail panel is untouched and no new dangerouslySetInnerHTML is introduced: stripMarkdown output lands in a JSX text node, so React escapes it. Three Playwright specs cover it: a description with a heading, inline code and a link renders as clean text with no literal syntax and no block element in the cell, the title tooltip carries the same stripped text, and a backend without a description still shows the placeholder. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * ui(models): polish the variant detail view and scope rendered Markdown The gallery detail pane rendered every field through the same two-column label/value row, including the description. Multi-paragraph prose in a value cell ran eight rows tall at the top of the pane on a ~1200px measure, breaking the grid's rhythm exactly where the eye enters. Move it into its own full-width block above the table, capped at a 68ch measure, keeping the label. Rendered Markdown had no scoped typography anywhere in the app, so a description opening with `#` inherited the browser default 2em inside a 13px surface while a `##` further down was indistinguishable from body text. Add a reusable .markdown-body block mapping h1-h6, paragraphs, lists, links, code, blockquotes, images and tables onto the existing type scale, and apply it to every renderMarkdown() consumer: the models detail, the backends detail, both Manage details and the voice library detail. Rebalance the variants list so the name leads. Backend and size drop from badge/secondary weight to muted metadata; the FITS badge goes entirely, since it was true of nearly every row and so said nothing, while the variant that does not fit keeps a warning badge and a dimmed name. AUTO-SELECTED stays marked because it answers what a plain Install produces. Rows share the parent's grid tracks via subgrid so name, backend, size and status line up down the list instead of raggedly following name length. Finally, make each variant row actionable. It looked like a list of choices but was inert text, with per-variant install hidden behind the split-button chevron elsewhere; each row is now a button onto the existing handleInstall(modelId, variant) path, with hover, keyboard focus and a disabled state while an install is in flight. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): collapse the listing to one row per model The listing supported has_variants=true, which narrowed to entries that DECLARE variants. With adoption at three entries that showed three rows, which is useless; it was always a placeholder. Replace it with the view that is actually useful: the deduplicated gallery. Show every entry installable in its own right and nothing twice, which means the parents plus every entry nobody references, and hide only the builds another entry already offers as a variant, since those are reachable through their parent. The parameter is renamed to collapse_variants accordingly: the filter is no longer a predicate on a row's own metadata but a view over the whole gallery. Default stays off, so the response with the parameter absent is unchanged. VariantReferencedIDs never reports an entry that declares variants of its own, so parents are always visible. That guarantees every hidden entry has a visible entry offering it, and no chain can strand a row. Variant resolution already refuses to install such a reference, but the listing has to stay coherent in the presence of a gallery that has one rather than silently swallowing entries. Self-references and dangling references hide nothing. The referenced set is computed over the whole gallery rather than over what the other filters left, so an entry is hidden because a parent offers it and never because of what the user searched for. The pass is over metadata already in memory: it resolves nothing over the network and triggers no variant description or size probe, so the listing's zero-probe contract still holds. The UI toggle keeps its behaviour (persistence, page reset, clear filters) and becomes "One row per model", which says what the user gets. Its localStorage key moves too, since the stored value meant a different filter. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): show the collapsed model listing by default The gallery listing is what a user reaches for to answer "what can I install". Answering that with several rows for the same model, one per build, makes the reader do the deduplication the collapsed view already does, so the collapsed view is the one to land on. The UI now asks for collapse_variants=true unless the toggle says otherwise. The server default is deliberately untouched: a request with the parameter absent still returns the full listing, because other API clients depend on that response and collapsing it under them would be a breaking change. Opting out omits the parameter rather than sending false, so it asks for exactly the listing everyone else gets. The stored preference changes vocabulary from '1'/'0' to 'on'/'off'. The previous build wrote it from an effect that runs on mount, so a stored '0' recorded that the page had been opened rather than that anyone chose the expanded view, and honouring it would pin every earlier visitor to a default they never picked. Only the new vocabulary counts as a choice; a legacy '1' meant the collapsed view and is what the new default gives anyway, so no earlier deliberate choice is lost. Collapsing being the default also changes what the empty state may say about it. An opted-into filter can be named as the cause of an empty result; a default cannot, so the filters keep the top line and the collapsed view drops to a hint below it, shown only once filters are narrowing the set. For the same reason "Clear filters" now restores the collapsed default instead of switching it off, and the toggle alone no longer counts as a filter worth offering to clear. The label stays "One row per model": it describes the view the user is looking at rather than an action, so it reads the same whether it is opted into or out of. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * gallery: group alternative builds of the same weights under variants Sweep the gallery for entries that are alternative builds of the same weights (different quantization, precision, or runtime format) and declare them as variants of a single parent row, so the listing offers one row per model instead of one row per quantization and the installer picks the largest build that this host can actually run. 41 families over 95 entries, turning 54 entries into variants. The parent is the bare-named entry wherever one exists, so nothing changes about what any existing entry installs. Ranking already selects the largest fitting build regardless of which entry is nominally the parent, so the parent only decides the pathological case where nothing fits. For the ten families that have no bare-named entry, the smallest build is the parent, since that is the one that has to install when nothing fits. Grouping was verified against the actual model filenames rather than the entry names alone. Different parameter sizes, languages, finetunes, and products that merely share a name prefix are left as separate rows: the qwen3.6 APEX and pi-tune finetunes, the DFlash and MTP speculative-decoding pairings, English-only versus multilingual Whisper, the QAT versus non-QAT Gemma 4 weights, and the abliterated FLUX build are all distinct models. Six parents define YAML anchors that other entries pull in with a merge key, which would have handed their variants to every merging child. For the two depth-anything anchors that would have made fourteen unrelated entries advertise the base model's builds as their own. All 26 merging children therefore carry an explicit empty variants list, which overrides the merged key and is equivalent to the key being absent. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): rank model variants by host backend preference Variant auto-selection filtered candidates by whether their backend can run on the host, then ranked the survivors by size alone. The backend never influenced the choice beyond that gate, so a Mac offered both an MLX build and a llama.cpp build kept neither filtered and installed whichever was larger, leaving the native accelerated runtime unused. The same held for CUDA against CPU on NVIDIA and ROCm against Vulkan on AMD. Rank by the host's backend preference between the fit tier and size: fit stays a filter, preference decides among the builds the host can equally hold, and size still separates builds on equally preferred runtimes. The preference data stays in one declarative table in pkg/system, now read by a prefix lookup instead of a switch, so adding a capability or reordering one host's runtimes is a one-line edit and the gallery's ranking code carries no per-backend branching. MLX joins the metal rule ahead of metal itself, which is inert for the existing alias-resolution consumer because no alias group holds a candidate named for mlx. An unrecognised backend, an unrecognised capability and an absent preference list all collapse to the previous size-only ordering rather than erroring or dropping candidates. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): rank variants by engine name, not backend build tag Variant auto-selection ranked candidates with SystemState.BackendPreferenceTokens, but that function and the variant ranker speak different vocabularies. BackendPreferenceTokens returns BUILD TAGS ("cuda", "rocm", "sycl", "vulkan", "metal", "cpu"). It exists to match installed backend build directory names like "llama-cpp-cuda-12" during alias resolution in ListSystemBackends. Variant ranking instead matches a gallery entry's `backend:` value, which is an ENGINE NAME: "llama-cpp", "vllm", "vllm-omni", "sglang", "mlx" and the rest. No engine name in gallery/index.yaml contains "cuda", "rocm", "sycl" or "vulkan". preferenceRank matches by substring, so on an NVIDIA host the tokens [cuda, vulkan, cpu] matched neither "llama-cpp" nor "vllm", every candidate scored identically and size alone decided. The NVIDIA, AMD, Intel, darwin-x86 and vulkan rules were all inert. Only metal appeared to work, and only because the token "mlx" happens to equal an engine name. The mismatch does not error, it silently deletes the feature. Separate the two vocabularies. backendBuildTagPreferenceRules keeps the build tags and its original output for every capability, including metal, whose "mlx" token is removed again; its alias-resolution consumer is byte-identical to before. engineNamePreferenceRules is new, holds engine names, and is read by the new EnginePreferenceTokens, which HostResolveEnv wires into the renamed ResolveEnv.EnginePreference. Both tables sit adjacent under one block comment naming each vocabulary and each consumer, and share one lookup helper so their semantics cannot drift. On NVIDIA the order is vLLM, then SGLang, then llama-cpp: vLLM is the throughput engine and a model published with a vLLM build is published that way because that build is the one worth running. AMD and Intel get the same order, since rocm and intel builds of both serving engines ship. Metal prefers mlx over llama-cpp. Vulkan prefers llama-cpp, the only LLM engine with a Vulkan build. darwin-x86 and unknown capabilities are deliberately absent rather than guessed at, degrading to the size-only ordering that predates preference. preferenceRank stays generic and names no engine and no capability, so adding a runtime remains a one-line table edit. Specs pin the NVIDIA and metal rules through the live table and the real HostResolveEnv wiring, so emptying the engine table or wiring the build tag source back in both go red. A regression table asserts BackendPreferenceTokens' original output per capability, and mirrored locks assert neither table carries the other's vocabulary. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs: record that variant selection ranks by engine before size A gallery entry can now declare variants, and selection ranks the builds a host can run by engine preference before size. Nothing told a contributor adding a backend that engineNamePreferenceRules exists, so a new engine would silently rank below every known one and lose to whatever build happened to be larger on hosts where it should have won. Document the step where a backend is added, warn against the sibling backendBuildTagPreferenceRules table (build tags, not engine names: the wrong table matches nothing, scores every candidate equally and disables the preference without erroring), and index it from AGENTS.md. Fix the authoring and user docs, which still claimed the largest surviving build wins. An author grouping builds under one entry has to be able to predict what a user gets, and size alone no longer decides it.

Ranking now puts engine preference ahead of size, so on NVIDIA a vLLM build wins over a larger llama.cpp one. An assistant reading the old schema would tell users the wrong thing. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): prefer llama.cpp over GPU serving engines on hosts with no GPU engineNamePreferenceRules had no row for the "default" capability, which getSystemCapabilities() returns both when no GPU is detected and when a GPU is present but under the 4 GiB VRAM floor. A missing row yields an empty preference list, which preferenceRank reads as "score everything equally", collapsing variant selection to size alone. That would be harmless if the hardware filter dropped GPU serving engines on such a host, but it does not. IsBackendCompatible derives support from the engine NAME, and "vllm" and "sglang" contain none of the darwin, cuda, rocm or sycl tokens it keys on, so they fall through to its closing "return true". A vLLM variant therefore survives on a CPU-only box and wins whenever its build is the larger of the two on offer: the machine installs vLLM in preference to llama.cpp. darwin-x86 had the identical hole. It was documented as a deliberate omission because nothing accelerates on an Intel Mac, which is true about acceleration and wrong about consequence: with every engine tied, download size decides. Add rows for both putting llama-cpp first. The GPU engines are enumerated behind it rather than left unmatched: an unmatched engine already ranks below every listed one, so llama.cpp would win either way, but unmatched engines also tie with each other and let size decide among them. Naming them fixes that order. MLX is left off the darwin-x86 row on purpose so it ranks last, since IsBackendCompatible admits darwin-tokened engines on that capability even though MLX needs Apple silicon. Preference orders survivors and never filters, so a model published only as a vLLM build is still installed on a host with no GPU; there is a spec for it. Surveyed every other value getSystemCapabilities() can return. nvidia, amd, intel and vulkan have rows; the l4t and cuda-refined values reach the nvidia row by prefix; "apple" and "" cannot reach the vendor fallthrough because the darwin and no-GPU branches return earlier. default and darwin-x86 were the only live holes. BackendPreferenceTokens and its build-tag table are untouched, and preferenceRank stays generic, naming no engine and no capability. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * gallery: prefer speculative-decoding builds when they fit Rank serving features between engine preference and size, so a host that can hold a DFlash or MTP build of a model's weights installs it instead of the plain build. Both answer faster for the same output, so whenever one survives the filters there is no reason to take the plain build. Precedence is now fit, then engine, then serving feature, then size. Engine outranks the feature deliberately: a serving feature makes the right engine faster, it does not make a wrong engine right, so a plain vLLM build still beats a DFlash llama.cpp build on NVIDIA. Fit outranks both, and a drafter pairing is strictly larger than the plain build, so the existing size filter drops it on a host too small for it before this axis is consulted. The order lives in a third preference table in pkg/system, alongside the build tag and engine name tables. It is the odd one of the three: not keyed by capability, because no hardware prefers a plain build over an equivalent faster one, and matched against whole segments of a gallery ENTRY NAME rather than as a substring of a backend value. Nothing on a gallery entry declares a serving feature, and tags are not a usable substitute: gemma-4-e2b-it:sglang-mtp carries an mtp tag while ornith-1.0-9b-mtp and qwen3.6-27b-nvfp4-mtp carry none. Entry names are author-supplied free text, unlike the closed engine vocabulary, so a short marker can turn up inside an unrelated word and whole segment matching is what keeps smtp-assistant from ranking as an MTP build. The block comment over the tables now documents all three together and states what each is matched against; the ranking code names no feature, so adding one stays a one-line edit to the table. 29c49203b rejected these entries as serving configurations rather than alternative builds of the same weights. The definition is now "alternative ways to serve the same model", which includes them, so regroup 14 entries under 12 parents. Judged by the files each entry points at: the qwen3.6, qwen3.5, qwen3 and deepseek pairings are the base GGUF plus a drafter, the gemma-4 QAT MTP entries are the same QAT weights at a different quantization plus an MTP drafter, and the two sglang MTP entries describe themselves as the same model served with speculative decoding. Left separate: qwen3.6-27b-mtp-pi-tune, a finetune with its own weights, and every entry whose base model LocalAI does not ship as its own row, which is the whole Qwopus line plus gemmable-4-12b-mtp, mimo-7b-mtp:sglang and qwen3.5-4b-dflash. None of the twelve parents defines a YAML anchor, so no variants key can leak through a merge key and no empty override was needed this time. The index was edited by line insertion only.

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

The parent entry is fine, but all four entries it was grouped with declared neither url: nor config_file:, and applyModel needs one of the two to have anything to build a config from. They carry urls: (plural), the informational HuggingFace link list, which is a different field. None of the four was ever independently installable, so grouping them routed a previously-working install into a broken entry. Give each the url: the parent already resolves through. virtual.yaml is a no-op base, and applyModel passes overrides to InstallModel separately from the fetched config, so backend: ds4, the parameters and the ssd/mtp options all still land exactly as authored. This is the same pattern the parent and many other GGUF entries in the index already use. Add the lint rule that should have caught this. checkVariantReferences only proved a target exists and is not itself a parent, which is structural validity: an entry can exist, declare no variants, and still be uninstallable. checkVariantTargetsInstallable mirrors applyModel's precondition instead, and names the parent, the target and the missing fields, because whoever hits it is reading a gallery entry and has no reason to know applyModel exists. The two index-driven resolution specs live in their own Ordered container: an Ordered container stops at its first failure, so sharing one with the lint rules let a lint breach skip them silently. Nine further entries gallery-wide have the same defect and are unrelated to variants, so they are broken installs that predate this branch. They are left alone here rather than buried in a regression fix, and widening the rule to cover every entry is deferred with them so the gate can ratchet up in one step instead of needing a skip list. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(gallery): install entries with no url or config_file on an empty base applyModel had three branches: fetch a base config from url:, build one from an inline config_file:, or fail with "invalid gallery model". An entry declaring neither is now installed on an empty base config, with overrides: and files: supplying everything. This is what the ~345 entries pointing at gallery/virtual.yaml were already getting. That stub is five lines carrying name, description and license. description and license are overwritten from the gallery entry immediately after the fetch, and the name never reaches disk because InstallModel prefers the install name. Crucially applyModel passes model.Overrides to InstallModel as a separate argument rather than merging it into the fetched config, so nothing an author writes depends on that base existing. The fetch bought a round trip to GitHub and nothing else. That makes f4ef80173 the wrong fix, so it is unwound. The four url: lines it added to the deepseek-v4-flash variants are reverted: they are a pointless network fetch now, and the family installs without them. Relaxing the branch would hide a real authoring mistake, so a payload rule replaces the base-config rule. An entry with no url, no config_file, no overrides and no files installs nothing and would leave an empty model directory while reporting success, so it is refused by name. The caller's request counts toward the payload, because its overrides and files are merged into the install exactly as the entry's own are. urls: (plural) is the informational link list and does not count, which is what the four entries that shipped broken had and why they were still uninstallable. checkVariantTargetsInstallable asserted every variant target declares a url: or a config_file:, which is no longer true and would now reject correct authoring. checkEntriesInstallSomething pins what survives instead, and covers every entry rather than only variant targets: the hazard is a half-written stanza and a parent can be one as easily as a target. The old rule was scoped to targets precisely because nine unrelated entries would have failed a gallery-wide version; those nine are valid now, so the deferred ratchet happens here in one step. 1280 entries, zero violations. Those nine (aurore-reveil_koto-small-7b-it, lfm2-1.2b, the six liquidai_lfm2 entries and deepseek-v4-pro-q2-ssd) become installable for free. Each carries overrides: and files:, and one of them is driven through the real install path in a spec. The no-fetch spec is paired rather than bare: an assertion that nothing was fetched proves nothing unless something could have been, so a control runs the same fixture with a url: pointing at a base config that is not there and asserts the install fails. Only then does the identical fixture without the url passing mean the read was skipped. Follow-up, deliberately not here: the ~345 entries still naming virtual.yaml can drop their url:. That is 345 index edits with their own risk, and mixing them in would bury this change.

Because the collapse composed with the search term, a build another entry offers as a variant could not be found by typing its name, so the toggle was the only way to reach those builds in the UI. A user who typed a name they knew existed got "no models found", which reads as "that model does not exist". Collapse is for browsing; search is for finding. An explicit search term now bypasses the collapse in the listing handler, so a name lookup returns matching entries whether or not a parent offers them. The term is trimmed once at the top of the handler, so whitespace is neither a search nor a bypass; previously an untrimmed blank term also narrowed the listing to whatever contained a space. Tag and backend deliberately do not bypass: they refine a listing the user is still reading rather than name an entry already known to exist. That makes the toggle redundant, so it goes, along with its i18n strings in all six locales, its localStorage persistence, its participation in "Clear filters" and the empty-state hint telling users to turn it off. The hint was doubly stale: it pointed at a control that no longer exists, and it was untrue exactly when a user has a search term, since searching now sees every build. The page always requests the collapsed listing. The stored preference key is left inert rather than cleaned up: nothing reads it, so a user who had the toggle off simply gets the collapsed view. collapse_variants stays on the API, off by default, because other clients want either view and the UI dropping its control is no reason to remove a working parameter. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): give the models gallery filter form a deliberate structure The filter area had accreted controls into one undifferentiated flow. The "Fits in GPU" toggle and the backend select were direct children of .filter-bar, the same wrapping container as the 18 taxonomy chips, so their position was decided by how many chips happened to wrap at the current width rather than by any layout intent. At narrow widths they were pushed past the right edge of that container's horizontal scroll and became unreachable entirely. Restructure into three bands inside the house .filter-bar-group wrapper that components/FilterBar.jsx already uses on Backends and the System tabs: 1. query scope: search plus the backend select 2. taxonomy: the chip row, alone, free to wrap 3. refinements: fits-in-GPU and context size, under a hairline rule The backend select leads the chips rather than trailing them because picking a backend disables the use cases that backend cannot serve, so it gates the row below it. Fits-in-GPU and context size share a band because they are one control group: the context size is the length the VRAM estimate is computed at, and that estimate is what the fits filter tests against. Chips had no visible keyboard focus indicator. The global focus ring is wrapped in :where(), so it carries the specificity of a bare :focus-visible, ties with .filter-btn and loses on source order, leaving focused chips showing their resting drop shadow. Restate the ring where it outranks both resting and hover. Also: aria-pressed on the chips, a real label association and aria-valuetext on the context slider (it steps over an index, so it announced "2"), disabled chip styling moved off inline styles, a prefers-reduced-motion block for the chip transition, and the hard-coded English "Context:" moved into all seven locales. No behaviour change: same filters, same state, same requests. Page reset on change, localStorage persistence and "Clear filters" verified unchanged. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): let the models recommendations panel fade into the background The "Recommended for your hardware" strip rendered at full height on every visit regardless of how many models were already installed, costing 186px at 1600px wide (287px at 1100px, where its cards wrapped to two rows) and pushing the first gallery row to y=554 / y=703. Make its prominence track how much the user still needs it. The panel now defaults to a one-line summary once anything is installed, and both the collapse choice and the existing dismissal persist: collapsed = explicit user choice, if one exists : installedCount > 0 The preference is three-valued on purpose. A boolean cannot tell "the user expanded it" apart from "the user has never chosen", and those need opposite handling when the installed count later crosses zero: someone who deliberately opened the panel on an empty instance should not have it collapse out from under them when their first model finishes installing. Collapsed keeps the card, icon, title and a suggestion count, so the panel is recovered by clicking what you are already looking at rather than by hunting. Expanded is unchanged, because for a user with nothing installed it was never the problem. Collapsed reclaims 145px at 1600 and 420, and 246px at 1100. Models.jsx gains a statsLoaded flag: stats initializes to installed:0, so reading it before the fetch resolves would render expanded and collapse a frame later, which is exactly the layout shove this removes. The dismissal key moves to the page's localai-models-* convention; the old localai_rec_models_dismissed is still read, never written, so an existing dismissal is honoured rather than resurrected by the rename. Accessibility: the disclosure is a real button whose accessible name is the visible title alone, with state on aria-expanded and aria-controls resolving in both states, because the grid is hidden via the hidden attribute rather than unmounted. That also keeps the four install buttons out of the tab order while collapsed. The app's global focus ring applies; no per-component outline is added, per the warning in App.css. Reveal animates opacity and transform only, never height, and both it and the chevron rotation are disabled under prefers-reduced-motion. Only en had a recommended block, so the other six locales were falling back to English for the whole panel. Translated the complete block rather than adding one orphaned key to files that would still render the title in English. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(downloader): recover from a leftover .partial on non-HTTP URIs An interrupted download leaves a `<file>.partial` behind. The partial handling in DownloadFileWithContext gated resume on `err == nil && uri.LooksLikeHTTPURL()`, so for any URI that is not literally http(s) the branch fell through to `else if !errors.Is(err, os.ErrNotExist)`, which with a nil err is true. The download then failed with an error wrapping nil: failed to check file ".../Ternary-Bonsai-27B-Q2_g64.gguf" existence: <nil> Every gallery file URI uses `huggingface://`, so a single interrupted download made that model permanently uninstallable until someone deleted the partial by hand. The `<nil>` in the message compounded it by pointing debugging at a filesystem failure that never happened. Restructure the handling as an explicit switch over the four real states: partial exists and is resumable, partial exists and is not resumable (discard and restart, as already done for an HTTP server without range support), no partial, and a genuine stat failure. The error branch is now only reachable with a non-nil error, names the path that was actually stat'd, and wraps with %w. Discarding is required for correctness and not merely convenience: the writer opens the partial with O_APPEND, so an un-resumed download would concatenate a fresh body onto stale bytes. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): tell the models gallery's variant rows apart, and let browsing see every build Both variant surfaces rendered name, backend and size. For two builds of one model that is close to no information: a variant exists precisely because the same weights are offered another way, so the backend usually matches and the sizes usually land within a few hundred megabytes. Comparing ternary-bonsai-27b-pq2 against ternary-bonsai-27b-q2-g64 meant reading two names that differ by a suffix nobody has defined anywhere in the UI. Report the quantization and the serving features on VariantView, and derive both server-side from the referenced entry rather than parsing names in the browser, so every client reads the same format out of the same file the installer will hand the backend. Quantization comes from overrides.parameters.model first, falling back to the file list. That order is load bearing: entries routinely ship a vision tower alongside the language model at a different quantization, so reading the file list first reports the mmproj's format. Matching walks `-` and `.` delimited segments right to left; `_` deliberately does not split, because it separates the parts INSIDE a quant token and splitting on it reports Q4 for a Q4_K_M build. A second, looser pass takes a segment's `_`-delimited tail, which catches the gemma-4-E2B_q4_0-it.gguf style; it runs second so a precise match can never lose to a fuzzy one further right in the name. An entry naming no format reports nothing, which is the honest answer for a backend served from a directory of weights. Features are the same tag-against-vocabulary match servingFeatureRank already ranks on, over the same host preference list. A build can therefore never be shown as faster than one selection did not actually reward, nor rewarded without being shown; a spec pins that agreement rather than trusting it. The compact dropdown gets the quantization on its meta line and the bare feature token. The detail row, which has the room, gets the quantization as its own monospaced column so precision lines up down the list, and the feature spelled out, because DFLASH names nothing to a user who has not met it. The referenced entry's description stays out of both: the detail row already renders the parent's prose above the table, and a second block per variant would push a three-variant list past a screen to restate what the columns now say precisely. The collapse toggle comes back. 462583f38 dropped it once search bypassed the collapse, on the reasoning that nothing was unreachable any more. That holds for finding a build whose name you know and does not hold for browsing: no sequence of actions enumerated the 68 builds the default view hides. Collapse is for browsing and search is for finding, and the toggle was the browsing half. It goes in the refinements band 0d4823362 established, not back among the taxonomy chips where its position depended on how many chips happened to wrap. It leads that band because it decides how many rows the other two refine over, and because unlike fits-in-GPU it is unconditional: a host with no GPU still browses. The search bypass is untouched and re-checked by a spec in the toggle's default state, since restoring the control must not restore the dead end it replaced. The empty-state hint returns but only without a search term, because a term bypasses the collapse and the hint would otherwise point at a control that cannot change the result. The stored preference reads 'on'/'off' only: an older build wrote '1'/'0' from an effect that ran on mount, so those record that the page was opened, not that anyone chose a view. Also fixes a latent flake it exposed. The collapse_variants spec compared whole response bodies byte for byte, and the listing envelope carries live host telemetry that drifts between two calls milliseconds apart, so it was asserting on the machine's memory pressure. It now compares everything the parameter governs -- the entries, their serialization and the paging -- and is green 25/25 where it was failing about one run in three. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): let the models gallery show a variant's full details The variant list in an entry's expanded detail row says how the builds differ: name, backend, quantization, size, and the auto-selected, base and serving-feature markers. It cannot say what any one of them is. A variant's own description, tags, license, source links and file list are unreachable anywhere in the UI, because while the collapse is on a variant has no gallery row of its own. Give each variant row an info control that reveals its entry, rendered by the same ModelDetail a top-level row gets, so a field added to the detail view appears here too. variantData is withheld from the nested render: a variant may declare variants of its own, and recursing would nest a picker inside a picker two levels deep already. An inline disclosure rather than a modal. The control sits inside a table row that is already expanded, inside a variant list within that; a dialog opened from there stacks a dismissal on a dismissal for a handful of extra fields about the entry the user is already reading, and breaks the page's own expand idiom. The third level is carried by an inset and a left rule instead of another card. The entry is fetched by exact name from the listing, once, on first use. The listing already returns every field the detail view renders, and a search term bypasses the variant collapse server-side, so no new endpoint is needed and neither the listing nor DescribeVariants gains any work. Expanding a row costs nothing; a variant nobody opens costs nothing. A name the listing no longer returns is stated, not blanked: an empty panel reads as a rendering fault rather than as a lookup that came back empty. The control is a sibling of the install button, not a descendant, so asking about a build can never install it. The variant list keeps its content-sized columns via a trailing filler track instead of max-content sizing, so the rows are unchanged while the panel spanning them gets the pane width its file table needs. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(gallery): let search respect the collapse instead of switching it off The models listing collapsed to one row per model, and an explicit search term turned that off wholesale. Searching while collapsed therefore answered with the individual builds a parent already offers, which are exactly the rows the view the user asked for has no place for: typing "mtp" returned qwen3.6-27b-nvfp4-mtp, a row that is invisible the moment the box is cleared. The bypass was the right shape of fix for the wrong half of the problem. What a search must not do is answer "no models found" for a build the gallery does hold; that does not require abandoning the grouping the user asked for. So the term is now matched against every entry either way, hidden builds included, and the collapse decides how a match is reported rather than which matches exist. Collapsing stops being a filter that drops rows and becomes a substitution: a match on a build another entry offers is reported as that entry, the one installable in its own right. Nothing becomes unfindable and nothing comes back that the requested view cannot show. Substitution happens after search, tag and backend, so every filter is judged against the build that really carries the name, tag or backend rather than against a parent that merely offers it; the other order would let backend=vllm match a parent whose own backend is something else. The price is that the surfaced row shows the parent's own metadata while the match was on a variant, which is what grouping means, and the alternative is claiming the gallery holds no such build. It happens before the count and the page math, so both describe the rows actually handed out rather than the matches that produced them. A parent already in the result keeps its own position and absorbs its matching variants there, which is what leaves the browsing listing ordered exactly as it was; a parent surfaced only by a variant takes the position of the first variant that surfaced it. Either way it appears once, however many of its builds matched and whether or not it matched itself. Search preserves gallery order rather than scoring, so a surfaced parent has a real position rather than an invented one. VariantParents never reports an entry that declares variants of its own, so a parent is never itself hidden and one hop always lands on a visible row. The handler follows exactly one anyway: refusing the second is what makes a gallery the linter would have rejected terminate rather than loop. The empty-state hint pointing at the toggle goes with it for every server-side filter. Substitution means a match is always reported as some row, so the collapse can no longer be why a term, a chip or a backend came back empty, and naming it there sends the user to a control that cannot change the result. It survives for the fits filter alone, which runs in the browser after the substitution and judges the surfaced entry's own size: there the build that fits really can be filtered out along with a parent that does not. Searching a build's exact name while collapsed now answers with its parent, so the result no longer contains the string the user typed. That is intended, and the row is the one they can act on, but it is a real rough edge: nothing on the row explains the connection. Closing it properly means reporting which variant matched so the UI can say so, which the listing does not do today. ResetGalleryModelCache is added for tests. The model cache is a package global keyed by nothing, so a background refresh one spec triggers can land in the middle of the next and answer it with the previous spec's gallery; the extra specs here made that fail about one run in five. It waits for the in-flight refresh to publish before clearing, since clearing alone only narrows the window.

mudler's LocalAI [bot]	465d488c90	fix(distributed): reject wrong-model requests at the backend (#10970) ... fix(distributed): reject wrong-model requests at the backend (#10952) In distributed mode the controller caches a NodeModel row naming a backend's host:port. A worker can recycle a stopped backend's gRPC port for a different model's backend, and probeHealth verifies liveness rather than identity, so the probe succeeds against whatever now occupies the port and the request is dispatched to the wrong backend. The caller gets a silent wrong-model answer. Nothing in the request could catch this: PredictOptions had no model field, so model identity crossed the wire only in ModelOptions.Model at LoadModel time, and the cached-hit path issues no LoadModel. Every backend's "model not loaded" guard checks a nil handle, which a process holding a different model passes, so the stale row was never dropped either. Add PredictOptions.ModelIdentity and enforce it at the point of use: - The controller populates it in gRPCPredictOpts from ModelConfig.Model, the same expression ModelOptions feeds to model.WithModel and therefore the same value the backend received as ModelOptions.Model. Both are read from one config value in one function, so they are equal by construction and the comparison cannot false-reject. - Backends compare it against what they loaded and return NOT_FOUND with a fixed sentinel. Enforced in pkg/grpc/server.go (27 Go backends), an interceptor in backend/python/common (all 36 Python backends, no per-backend change), and the llama-cpp / ik-llama-cpp / ds4 C++ servers. That is every backend with real exposure: kokoros answers all four RPCs with unimplemented and privacy-filter implements none of them. - The router's reconcile drops the stale replica row on a mismatch, so the next request reloads somewhere correct. Empty means "skip the check" on both sides: a controller that predates the field sends nothing, a backend loaded by such a controller has nothing to compare, and the C++ server synthesizes PredictOptions internally for ASR. That keeps upgrades working in both directions. Scoped to the four PredictOptions RPCs. TTSRequest.model and SoundGenerationRequest.model are deliberately NOT validated: FileStagingClient already rewrites them to worker-local absolute paths, so in distributed mode they already differ from the load-time value and comparing them would reject valid requests. IsModelMismatch requires both the NOT_FOUND code and the sentinel, unlike the neighbouring helpers which accept either. insightface's Embedding returns NOT_FOUND "no face detected" on a PredictOptions RPC, and a code-only check would drop a healthy replica row on every faceless image.

mudler's LocalAI [bot]	e55cc3e2a7	fix(worker): bound the gRPC port allocator and stop leaking dead backends' ports (#10968) ... The worker's gRPC port allocator grew monotonically with no upper bound: nextPort started at the base port and incremented whenever freePorts was empty, and nothing checked 65535. Past that it handed out integers that cannot be bound, surfacing as an opaque "backend won't start". #10961 estimated this needed ~15,000 concurrent-peak allocations, i.e. effectively unreachable. It is not, because of a second defect: the "process died unexpectedly" branch in startBackend deleted the process map entry without releasing its port at all. That port was leaked, never quarantined and never reused. A crash-looping backend leaks one port per restart, so a backend dying every 30s walks 50051 to 65535 in about five days. The leak, not concurrent peak, is the realistic route to exhaustion. Fixing the leak alone would have been wrong. Releasing that port makes it re-bindable, and the death path is the one teardown path with no request/reply to carry StoppedProcessKeys back to the controller (#10952's eager row removal), so a stale NodeModel row could then resolve to a live listener belonging to a different backend. probeHealth verifies liveness, not identity, so the request is silently misrouted. The 15s port quarantine does not cover this: the only reaper is the per-model health check at ~45s, and it can be disabled outright. The residual was masked only because the port was never rebound. So both are fixed together: - The allocator takes an explicit [basePort, LOCALAI_GRPC_MAX_PORT] range and returns ErrNoFreePort naming the range, the live backend count, the quarantined count, and the knob to raise. Exhaustion is now diagnosable instead of surfacing as an unbindable port. - Released ports carry per-key affinity: a port is offered back to the process key that last held it before any other key. Process keys (modelID#replica) and NodeModel rows (nodeID, modelName, replicaIndex) are isomorphic, so a port that can only be re-bound by its previous owner can only ever be named by that owner's row, which that key's re-registration overwrites. Misrouting to a different model becomes impossible by construction rather than by racing the quarantine timer. Affinity is a preference, not a reservation: under range pressure an owned port is stolen with a warning, because a guaranteed outage is worse than a rare misroute window on a port long out of quarantine. Claiming a port evicts its previous owner's entry, keeping ownership injective over ports so the affinity map can never exceed the range width regardless of how many distinct model keys the worker sees. Ownership also expires. It is only load-bearing while a controller row could still name the port, which the per-model reaper bounds at roughly 45s, so it lapses after five minutes and the port becomes ordinary free space again. Holding it indefinitely would have made every distinct model the worker ever served consume a port permanently: every release path is keyed, so nothing would ever be unowned, the allocator would climb to the end of its range on distinct-key count rather than concurrency, stealing would become routine, and the steal warning would tell operators to widen a range that was not the constraint. With expiry, reaching the steal branch means the worker is genuinely out of concurrent capacity, so that advice is correct when it appears.

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

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

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

mudler's LocalAI [bot]	fb4c61d1c9	fix(distributed): configurable remote model-load timeout, and reap the load when it times out (#10948) ... * fix(distributed): make the remote LoadModel deadline configurable The router hardcoded a 5 minute gRPC deadline for the remote LoadModel call. Staging finishes before the timer starts, so those five minutes cover only the worker backend's own checkpoint load and pipeline init. A cold load of meituan-longcat/LongCat-Video-Avatar-1.5 (~83 GB) on an ARM64 Thor worker fails at exactly 302s with DeadlineExceeded while the backend process is still making progress (CPU time accumulating, RSS moving as weights are mapped), so the load was cut short rather than wedged. Add LOCALAI_NATS_MODEL_LOAD_TIMEOUT / --model-load-timeout mirroring the existing backend-install timeout knob, defaulting to 5m so unset clusters keep today's behaviour. The cold-load hold ceiling (which bounds how long one load may hold the per-model advisory lock) was derived from the install timeout alone, so raising the load deadline past it would have been silently clipped. Derive it from both budgets via ModelLoadCeilingFor: max(install + load + 5m staging margin, 25m) With the defaults that is 15m + 5m + 5m = 25m, identical to the previous constant, and the 25m floor means shrinking either budget can never tighten the ceiling below what clusters relied on before. Assisted-by: Claude:claude-opus-4-8 golangci-lint Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed): reap the abandoned replica when a remote load times out The gRPC deadline on the remote LoadModel call only cancels the client side. A backend blocked in a synchronous weight load never observes its cancelled handler context, so when scheduleAndLoad gave up it left the worker loading with nobody waiting for the result. Observed on an ARM64 Thor worker loading LongCat-Video-Avatar-1.5: the client returned DeadlineExceeded at 302s, and the backend process was still alive 30 minutes later having pulled ~57GB from HuggingFace. Every retry stacked another multi-GB loader on the worker; they had to be reaped by hand via POST /api/nodes/:id/models/unload. Send backend.stop for the exact `modelID#replicaIndex` process key we just abandoned. The exact key matters: a bare model ID stops every replica on that node, including healthy ones serving traffic. Only a deadline or cancellation triggers the reap. Any other LoadModel failure is the backend answering, which means its handler returned and the process is idle - stopping it there would discard a warm process and its downloaded weights. The reap is best-effort and never replaces the load error the caller is waiting on. The `modelID#replicaIndex` format was already hand-rolled in two places (the worker's buildProcessKey and pkg/model's log store). Rather than add a third, export model.BackendProcessKey from pkg/model, the lowest common dependency of both sides.

mudler's LocalAI [bot]	626ae4d51e	fix(model-artifacts): materialize longcat-video on the controller, and support companion repos (#10949) ... * fix(model-artifacts): materialize longcat-video checkpoints on the controller longcat-video loads a checkpoint directory: its backend.py takes request.ModelFile when os.path.isdir(request.ModelFile) and otherwise falls back to snapshot_download. That places it in the same class as transformers/vllm/diffusers/sglang, but the allow-list added in #10910 did not enumerate it, so PrimaryArtifactSpec returned no managed artifact for a bare HuggingFace repo id. The consequence in distributed mode: nothing was acquired on the controller, ModelFileName fell through to the raw repo id, and staging skipped the resulting phantom /models/<owner>/<repo> path. The worker received a blank ModelFile, fell back to request.Model, and downloaded ~83GB from HuggingFace inside the remote LoadModel deadline - so the load could only ever fail with DeadlineExceeded while an abandoned backend process kept downloading. Note this materializes the full repository. The backend restricts its own snapshot_download with allow_patterns, and the avatar repo ships both base_model/ and base_model_int8/ where only one is ever loaded; inferred specs have no way to carry patterns today. Tracked separately. Assisted-by: Claude:opus-4.8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed): warn when staging skips a non-existent model path stageModelFiles logs "Staging model files for remote node" up front, then silently drops any path field that does not exist on the controller. The skip itself is legitimate and must stay: a backend outside managedArtifactBackends that takes a bare HuggingFace repo id gets an optimistically constructed path (ModelFileName falls through to the raw model reference) that was never materialized, and sources its own weights on the worker. Erroring would break those configs. But at debug level the operator is left with a reassuring staging line and no trace of the skip, so a genuine controller-side acquisition gap is indistinguishable from a healthy pass-through - it surfaces much later as a remote LoadModel timeout, on a worker that is quietly downloading tens of gigabytes. Raise the skip to warn and name the field, path, node and tracking key. Behavior is unchanged. Assisted-by: Claude:opus-4.8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(model-artifacts): allow a config to declare companion artifacts A composed pipeline needs more than one HuggingFace snapshot. LongCat-Video-Avatar-1.5 loads its own transformer but takes the tokenizer, text encoder and VAE from the separate LongCat-Video base repo, so a single-artifact config cannot express it and the backend is left to fetch the second repo itself at load time. Widen the artifact model to target: model plus any number of named target: companion entries. Normalize accepts the new target and constrains a companion name to [a-z0-9][a-z0-9_-]{0,63} because that name is the option key the backend later receives; a companion may not claim primary_file, which only means anything for a load target. ModelConfig.Validate requires exactly one primary and requires it first, since Artifacts[0] is what ModelFileName, size estimation and staging all resolve from. Both acquisition paths now loop instead of touching index 0 alone: preloadOne for an already-installed config, bindPrimaryArtifact for a gallery install. Failure policy differs by provenance. An inferred primary keeps its warn-and-fall-back, because the legacy download path still exists for it. Companions are explicit by construction, so they are all-or-nothing: a config naming one is asserting the backend needs it, and failing at the acquisition boundary is far more legible than a missing-weights error surfacing later inside the backend. The cache key is deliberately unchanged. It hashes source identity only, never name or target, so every already-installed managed model still hits its existing snapshot instead of silently re-downloading. Two specs pin that: one proving a companion and a primary with identical sources agree on the key, and one pinning the digest of a known primary outright. Assisted-by: Claude:opus-4.8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(model-artifacts): hand resolved companion snapshots to the backend A materialized companion is useless until the backend can find it, and its location is a content-addressed cache key that does not exist until the artifact resolves. A static gallery override cannot carry that, and persisting it into the config YAML would rot the moment a re-resolve produced a new key. Synthesize it instead at load time: each resolved companion becomes "<artifact name>:<snapshot path>" in ModelOptions.Options, reusing the key:value convention backends already parse for options like attention_backend. The value stays relative to the models directory so a remote worker can resolve it under its own ModelPath once staging has rewritten the model root. An option the author set explicitly always wins, so pinning a companion to a local checkout still beats the managed snapshot. longcat-video resolves base_model through ModelPath, the same convention qwen-tts, voxcpm, outetts and ace-step already use for companion assets. Its sibling-directory heuristic is deleted: it looked for a LongCat-Video directory next to the model, which cannot exist under the content addressed .artifacts/huggingface/<key>/snapshot layout, so it was dead code the moment the model became managed. The gallery entry declares both repositories and restricts each with allow_patterns. The avatar repo ships base_model/ and base_model_int8/ and only ever loads one, so fetching the whole repo would roughly double the download. The patterns match the entry's own options (use_distill true, use_int8 default false); enabling use_int8 here also requires adding base_model_int8/**, which is called out in the entry. Assisted-by: Claude:opus-4.8 [Claude Code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed): stage managed artifact trees from the models root Staging anchored the worker's models directory on the primary snapshot whenever a model was managed, so a companion snapshot could not reach the worker at all. frontendModelsDir was derived by stripping the Model relative path off the end of ModelFile. For a managed artifact nothing matches: ModelFile is .artifacts/huggingface/<key>/snapshot while Model stays a bare HuggingFace repo id, so the strip was a no-op and the "models directory" came out as the snapshot itself. Two consequences, both silent. Staging keys lost the .artifacts/huggingface/<key>/snapshot prefix, so two snapshots of one model were indistinguishable on the worker. And a companion, which lives in a sibling snapshot directory outside the primary, fell outside that directory entirely: StagingKeyMapper.Key collapsed its files to bare basenames and resolveOptionPath could not resolve the relative option at all, so it was skipped without a word. Derive the models root from the artifact tree instead when the path runs through it, and compute the worker's ModelPath from the file's path relative to that root rather than from the Model field. The legacy layout is unaffected: where Model really is the relative path, the new derivation reduces to the old one, which a regression spec pins. This deliberately changes an invariant that router_dirstage_test.go pinned: for a managed primary, ModelFile and ModelPath were both the snapshot directory, and staging keys were relative to it. Now ModelFile is the snapshot, ModelPath is the models root above it, and keys keep the full relative path. That spec is updated rather than accommodated, with the reasoning recorded inline, because the old invariant is exactly what made a sibling companion unreachable.

mudler's LocalAI [bot]	a89d780707	fix(gallery): keep multi-file HF install progress proportional during verify (#10908) ... The artifact progress bridge mapped every PhaseVerifying event to a flat 95%. The materializer emits PhaseVerifying once per file (from each file's AfterDownload hook) and downloads run sequentially, so the first small file to finish pinned the bar at 95% - and, because progress is monotonic, it stayed at 95% for the entire remaining download (e.g. a 70GB checkpoint reporting 95% at 410MB / 69.7GB). Track per-file verify proportionally to the running aggregate bytes, the same way downloading does. CurrentBytes already reflects "completed files + this file", so the percentage advances honestly. The flat 95%/99% is now reserved for the genuinely once-per-install Committing/Persisting phases.

When another service already listens on 9090 the suite does not fail fast: the server goroutine logs the bind error and the specs then poll whatever is squatting the port until Eventually times out. On machines where 9090 is permanently taken this makes the pre-commit coverage gate impossible to pass.

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

SetDefaults injected the llama.cpp server options cache_reuse (ApplyServingDefaults) and parallel (ApplyHardwareDefaults, re-applied per selected node by the distributed router) onto every model config regardless of backend. Every other backend ignores options it does not understand, so this was harmless until longcat-video, which strictly validates its options and fails LoadModel with "unknown model option(s): cache_reuse, parallel". Gate both injections behind a new UsesLlamaCppServingOptions allow-list (llama-cpp plus the empty/auto-detect case that resolves to llama.cpp from a GGUF file, mirroring how llamaCppDefaults is registered). This follows the existing UsesLlamaSamplerDefaults precedent for llama-only defaults. The typed NBatch field is deliberately left alone: it is a proto field every backend simply ignores, which is why batch never triggered the error.

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

LocalAI [bot]	29001a88c1	fix(distributed): don't let a dead worker pin the model-load advisory lock (#10600) ... * fix(distributed): don't let a dead worker pin the model-load advisory lock In distributed mode a chat request could fail with: failed to route model with internal loader: routing model ...: loading model ...: advisorylock: acquiring lock <id>: ERROR: canceling statement due to lock timeout (SQLSTATE 55P03) Root cause is two independent defects in the cross-replica model-load path: 1. SmartRouter.Route holds a per-model PostgreSQL advisory lock for the whole cold-load sequence, which includes installBackendOnNode -> InstallBackend, a NATS request-reply with a 15m deadline (DefaultBackendInstallTimeout) that ignored ctx. When the chosen worker died mid-install, the holder sat on the lock for up to 15m. The detached loadCtx (WithoutCancel) had no deadline, so nothing capped the hold. 2. The acquiring statement, pg_advisory_lock(), is subject to any deployment global lock_timeout. A common operator setting (e.g. 10s) aborts the wait with SQLSTATE 55P03, so every other replica's request for that model hard -errored instead of waiting for the in-progress load and reusing it. For the ~15m window the model was effectively unroutable. Fixes: - advisorylock.WithLockCtx (postgres): SET lock_timeout = 0 on its dedicated connection (RESET before it returns to the pool) so the Go context, not a deployment-wide GUC, governs how long we wait. Waiters now block and then re-check, reusing the model another replica just loaded. - SmartRouter: bound the detached loadCtx with a single ModelLoadCeiling so the lock is always released in bounded time even if a sub-step wedges. Default is the configured backend.install deadline + 10m (staging + LoadModel margin), so a legitimately slow load is never cut. - installBackendOnNode: use singleflight.DoChan + select on ctx.Done() so the install wait honors cancellation; the ceiling can then actually free a caller pinned behind a dead worker. The shared install still coalesces via singleflight. Reproduced both defects as failing tests first (a real 55P03 against a testcontainer with a short lock_timeout; a wedged install that blocks Route) and confirmed green.

Safe for SmartRouter.Route (its loadCtx now carries the model-load ceiling) but unsafe for the schema-migration callers that pass context.Background(): a holder whose session never releases would hang them indefinitely. Derive the server-side lock_timeout from the caller's context instead: its remaining budget plus a margin (so the Go context's cancellation still wins with a clean error and the server bound is only a backstop), or a finite 30m backstop when the context has no deadline. Never zero - "wait forever" is no longer possible, while a deployment's hostile short lock_timeout is still overridden so legitimate cross-replica waits don't fail with 55P03. Added a spec proving a deadline-less waiter gives up at the (shrunk) backstop rather than hanging.

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.

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]	f3d829e2ef	feat(distributed): add LOCALAI_DISTRIBUTED_SHARED_MODELS to skip staging on shared volumes (#10556) (#10566) ... In distributed mode, even when the frontend and workers share the same models directory via a shared volume mount, starting a model on a worker re-staged (re-downloaded) it: stageModelFiles always uploads model files into a tracking-key-namespaced subdir on the worker, and the staging probe only checks that staged location, so a file already present on the shared volume at the canonical path was never reused. Add a config switch LOCALAI_DISTRIBUTED_SHARED_MODELS (default false). When enabled, the operator asserts that all nodes mount the SAME models directory at the SAME path, so staging is unnecessary: the frontend's absolute model paths are already valid on the worker. In that mode stageModelFiles returns the cloned opts unchanged without uploading, leaving the path fields pointing at their canonical absolute paths so the worker loads them directly from the shared volume.

Several features keep process-local state surfaced to the API (finetune/quant jobs, agent tasks, model configs) and each hand-wired the same in-memory + NATS broadcast + read-through-store legs - or forgot to, reintroducing cross-replica staleness. SyncedMap makes that consistency a configuration choice: - local writes mutate the map, write through the Store, then broadcast a delta; - the apply path is memory-only and never re-publishes or re-writes the Store (structural echo-loop guard, mirroring galleryop.mergeStatus); - on Start and on NATS reconnect the map re-hydrates from the source (Store, else Loader); an optional periodic Reconcile repairs silent drift; - standalone mode (nil NATS client) is a strict in-memory no-op. Reconnect re-hydrate is wired via a new *messaging.Client.OnReconnect callback, consumed through an optional type-assertion so MessagingClient stays minimal. Adds messaging.SubjectSyncStateDelta and a reusable testutil.FakeBus (synchronous in-process MessagingClient with wildcard matching) for adopter tests.

The file persister now owns its own task set so the write-through path does not re-enter the SyncedMap lock (deadlock guard). - The distributed NATS client is not available at construction (start() precedes initDistributed), so it is injected via SetTaskSyncNATS, which rebuilds the still-empty map before Start/hydrate.

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

The same response also lacked in_flight_count and model_count. Add NodeRegistry.GetWithExtras, mirroring the existing List vs ListWithExtras split: bare Get stays cheap for the routing hot paths and existence checks, while the detail endpoint uses the enriched variant to attach the labels map and live counts.

Two failures hit deployments that use the default SQLite auth database: 1. advisorylock executed PostgreSQL-only SQL (pg_advisory_lock / pg_try_advisory_lock) unconditionally. On a SQLite auth DB the job store, agent store and node registry migrations failed with "no such function: pg_advisory_lock". WithLockCtx/TryWithLockCtx now branch on the gorm dialect: PostgreSQL keeps the cross-process advisory lock, every other dialect uses a context-aware, per-key in-process lock (a SQLite auth DB is effectively single-process, so serializing within the process is sufficient). 2. The SQLite auth DSN set no busy timeout, so transient SQLITE_BUSY over network-backed storage (SMB/CIFS/NFS, e.g. Azure Files) failed the auth migration immediately with "database is locked". The DSN now sets _busy_timeout=5000 and _txlock=immediate (caller-supplied values are preserved). WAL is intentionally not enabled since its shared-memory mmap does not work over network filesystems. Docs note that PostgreSQL should be used when the data directory lives on shared storage.

LocalAI [bot]	79783120dd	fix(config): gate parallel-slot default on per-device VRAM too (#10485) (#10507) ... The first #10485 fix (#10494) made the Blackwell physical-batch boost per-device/context-aware, which neutralized the big compute-buffer OOM, but the reporter's 2x16 GiB consumer Blackwell still OOM'd. Tracing the post-fix log: the model now loads its weights, builds the main context and warms up fine, and dies only on the *last* allocation — the MTP draft context's 800 MiB KV cache on the tighter device. #10411 changed only two defaults: the physical batch (now gated) and a VRAM-scaled parallel-slot count. The KV cache is unified (n_ctx_seq == full context proves slots share the budget, so parallel doesn't multiply KV), but n_seq_max=4 still adds per-slot compute-graph / context-checkpoint / output scratch. On a device packed ~99% by a 27B model spanning both cards, that overhead is the few-hundred-MiB straw — which is why reverting #10411 (and only #10411) restores a working load. Gate the parallel-slot default on the same per-device headroom predicate as the batch boost: when a large context already fills a single card (largeContextForDevice), keep n_parallel=1. A user running one big-context model that barely fits across two consumer GPUs is not serving four concurrent tenants. Small contexts and large unified-memory devices (GB10) keep full concurrency. Applied on both the single-host path and the distributed router. Also make the auto-tuning visible and reversible (the debugging here needed DEBUG logs and a git bisect): - Log the effective performance-relevant runtime options at INFO once per model load ("effective runtime tuning …": context, n_batch, n_gpu_layers, parallel, flash_attention, f16) so an admin can see what will run and pin or override any value in the model YAML. - LOCALAI_DISABLE_HARDWARE_DEFAULTS=true skips the hardware auto-tuning entirely (mirrors LOCALAI_DISABLE_GUESSING) for stock llama.cpp behavior.

LocalAI [bot]	0d6de15ae9	fix(config): per-device VRAM headroom for Blackwell defaults (#10485) (#10494) ... The hardware-tuned defaults from #10411 were measured on a GB10 / DGX Spark (128 GiB unified memory) and over-provisioned multi-GPU consumer Blackwell (e.g. 2x16 GiB RTX 50-series) into CUDA OOM during model init: - The Blackwell physical batch (512 -> 2048) sets both n_batch and n_ubatch. The compute buffer scales ~n_ubatch * n_ctx and is allocated PER DEVICE (it can't be split across GPUs), so a large context turns ub2048 into multi-GiB of scratch that must fit one 16 GiB card. - The VRAM-scaled parallel-slot default tiered off TotalAvailableVRAM(), which SUMS all GPUs (2x16 -> "32 GiB" -> 8 slots), but the allocations are per-device. Make both decisions per-device and context-aware: - xsysinfo.MinPerGPUVRAM() reports the smallest device's VRAM; localGPU() uses it so the parallel tier and batch guard reason about one card. - PhysicalBatchForContext(gpu, ctx) raises the batch only when the extra compute buffer fits VRAM/4 at this model's context (16 GiB crosses over ~174k ctx, 32 GiB ~349k; GB10 reports system RAM so it still clears it). - Apply hardware defaults AFTER runBackendHooks in SetDefaults so the GGUF-guessed context is resolved before the batch decision. - The distributed router gates the node batch the same way. Unified-memory devices (GB10, Apple) report system RAM as their single device's VRAM, so they keep the prefill win.

LocalAI [bot]	e5620989dd	refactor(distributed): make in-flight tracking coverage a compile-time contract (#10476) ... PR #10475 fixed SoundDetection in-flight tracking, but the underlying trap remains: InFlightTrackingClient embedded the whole grpc.Backend interface "for passthrough of untracked methods", so any newly added inference method is silently satisfied by the embedded passthrough and never wrapped with track(). That leaves onFirstComplete unfired and in-flight stuck at 1 - the exact SoundDetection bug, waiting to recur for the next backend method. Close the gap at the type level instead of relying on reviewers to remember: - Split grpc.Backend into two composed sub-interfaces: InferenceBackend (methods that are one discrete inference call and must be tracked) and ControlBackend (control-plane calls plus the streaming constructors whose work spans the returned stream, safe to pass through). The classification now lives next to the interface it documents. - InFlightTrackingClient embeds only grpc.ControlBackend and implements every InferenceBackend method explicitly, delegating to an inner InferenceBackend. A `var _ grpc.Backend = (*InFlightTrackingClient)(nil)` assertion makes the package fail to compile if any inference method is left unwrapped. Now adding a method to InferenceBackend is a build error (at the assertion and every call site: "does not implement grpc.Backend (missing method X)"), not a silent runtime leak - and the obvious fix is to copy a neighbouring wrapper, which calls track(). No runtime guard or reviewer vigilance required. Pure refactor: the composed Backend interface is identical to the old flat one, so all implementers and consumers are unaffected (verified with a full `go build ./...`). Behaviour is unchanged; the existing nodes suite passes.

LocalAI [bot]	fc618dcee6	fix(distributed): track in-flight for SoundDetection requests (#10475) ... The distributed router wraps backend clients in InFlightTrackingClient so the eviction logic knows which replicas are actively serving. Every inference method must be wrapped: track() increments in-flight on entry and decrements (plus fires onFirstComplete, which releases the load-time reservation) on return. SoundDetection was added after the tracking client and never got a wrapper, so its calls fell through to the embedded passthrough Backend. The increment/decrement never ran and, critically, onFirstComplete never fired, so the reservation set at model load was never released - leaving in-flight stuck at 1 and the replica permanently ineligible for eviction.

In distributed mode a model/backend install marks OpStatus.Cancellable=true while downloading, but the gallery_operations row never recorded it: UpdateStatus persisted only progress/status and Create left the cancellable column at its zero value. After a replica restart Hydrate rebuilt the op with cancellable=false, /api/operations reported false, and the UI hid the cancel button - the orphaned op then lingered until the 30-minute stale reaper expired it ("stays there on restart, can't cancel, after a bit it expires"). Persist the flag on every progress tick and at row creation (installs are cancellable, deletes are not), and clear it on terminal transitions. A rehydrated in-flight op is now cancellable, so an admin can dismiss the orphaned op immediately instead of waiting out the reaper. The functional cancel path already survived restart (CancelOperation persists store.Cancel even with no live CancelFunc); this restores the UI affordance that drives it.

This carries only the incremental review fixes and tests that postdate that merge — the feature itself is not re-introduced. Review fixes: - openai_completion.go: remove the dead `elem >= 0` conjunct in applyAnyText (the `elem < 0` guard above already returns). - application.go: collapse ResolvePIIPolicy's inline re-implementation of PIIIsEnabled to a single cfg.PIIIsEnabled() call (sole source of the "explicit pii.enabled wins, else cloud-proxy default" rule) and return true past the !enabled guard where it is provable. - pattern.go: hoist the triple `appConfig != nil && EnableTracing` check in patternDetector.Detect into one local. - grammar.go: MaxQuantifier was 4096, but Go's regexp/syntax rejects repeat bounds above 1000 at Parse time, so walk()'s {n,m} guard could never fire — dead code shadowed by the parser. Lower it to 512 so a bound in (512,1000] is rejected here with an actionable error; >1000 still fails closed via Parse. Specs pin the relationship so the guard can't silently revert. - PatternListEditor.jsx: clamp a directly-typed negative min_len to >=0 and force the DOM value back when clamping (min={0} only constrained the spinner, so a negative reached saved config and silently disabled the length filter). Tests: - piipattern_test.go: MaxQuantifier guard specs (must stay live, not dead). - model-config.spec.js: assert the min_len clamp, and that entity_actions collapses a duplicate group to a single row (map semantics; regression guard against emitting an array that drops a row on save). - tests/e2e-backends: token_classify capability driving the TokenClassify gRPC RPC against the backend image, asserting byte-correct, UTF-8 rune-aligned spans (entity.Text == text[start:end]) at threshold 0. Verified on CPU via `make test-extra-backend-privacy-filter` (3/3 specs). - Makefile: test-extra-backend-privacy-filter wrapper. - tests/e2e: e2e_pii_ner_test.go drives /api/pii/analyze + /api/pii/redact (mask + block) through the full HTTP -> detector -> redactor path; gated on PII_NER_MODEL_GGUF so the default suite is unaffected. - .github/workflows/tests-pii-ner-e2e.yml: path-filtered / nightly CI job running the container harness on CPU.

File-staging progress lived only in the SmartRouter's in-memory StagingTracker on the replica performing the transfer. In a multi-replica deployment behind a round-robin load balancer, a /api/operations poll that lands on any other replica saw no staging row, so the progress ("processing file ... Total ... Current ...") flickered in and out as polls rotated between frontends. Mirror the pattern already used for gallery-install progress: the origin replica broadcasts staging ticks over NATS (SubjectStagingProgress, a new staging.<model>.progress subject), and peers merge them via ApplyRemote (SubscribeBroadcasts on the wildcard). Byte-level ticks are leading-edge debounced (~1/s); Start/FileComplete/Complete always publish. A locally-owned op stays authoritative so the origin's own echo and stray peer events can't clobber it, and mirrored remote ops expire after a TTL so a missed Done event can't leave a phantom row.

Staging a multi-GB model takes minutes - far longer than any client keeps its HTTP request open - so a browser refresh, an ingress/LB idle-timeout, or a round-robined retry landing on another frontend replica cancels the request context and aborts the upload with "context canceled" mid-transfer. Large models then never finish staging, so they never load (observed in a 2-replica deployment: both frontends repeatedly failed to stage a 15.7 GB GGUF, each attempt dying at a different offset). Bind the cold load (staging + LoadModel + the per-model advisory lock) to context.WithoutCancel(ctx): it keeps the request's values (prefix chain) but drops cancellation/deadline.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * 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. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ced): server-side windowing for realtime sound detection (option B) Adds an optional server-driven sliding-window classifier so a sound-only realtime client only has to stream audio (no input_audio_buffer.commit): - Pipeline.sound_detection_window_ms / sound_detection_hop_ms config knobs. When both > 0 on a sound-only session, the server classifies the last window of streamed audio every hop and emits a conversation.item.sound_ detection event; the input buffer is trimmed to one window so a long stream stays bounded. When unset, the session stays client-driven (option A). Runs independent of VAD (sound events are not speech). - handleSoundWindow (ticker) + classifySoundWindow (one tick, extracted so it is unit-testable) + writeWindowWAV, which declares the true InputSampleRate (NewWAVHeaderWithRate) so the classifier resamples correctly. Goroutine is started after toggleVAD and torn down with the session (close + wg.Wait). - Register pipeline.sound_detection (+window_ms/hop_ms) in the config meta registry; the earlier realtime commit added pipeline.sound_detection without a registry entry, failing TestAllFieldsHaveRegistryEntries. This fixes that and covers the two new knobs. Tests: classifySoundWindow emits an event + trims the buffer to one window, no-ops on too-little audio; writeWindowWAV declares the given sample rate. go build/vet + golangci-lint (new-from-merge-base) clean; config + openai suites green. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * 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. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ced): add tiny/mini/small GGUF model gallery entries Publishes the rest of the CED family (same architecture, metadata-driven port verified end-to-end on ced-tiny) to mudler/ced-{tiny,mini,small}-gguf and adds 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. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * chore(ced): point gallery entries at the consolidated mudler/ced-gguf repo 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. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * 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. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * 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. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * 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. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(ced): silence gosec G304/G103 + govet unsafeptr on audited paths - 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.

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

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

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