Selection needs each variant's size to decide whether it fits and to rank
largest-first. 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.

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.

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.

Adds the first real meta entry to the gallery index. 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.

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.

Fills the read-only backend, quantization and inferred_min_vram fields on
meta gallery candidates and opens a PR, modeled on the existing
checksum_checker job. 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.

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.

Adds Ginkgo specs that parse the shipped gallery/index.yaml and enforce
the invariants that keep meta entries safe: a legacy url fallback equal
to the final candidate's url, references only to existing non-meta
entries, a min_vram floor on every candidate but the last-resort one,
a capability drawn only from the vocabulary the system can report, and
descending VRAM floors within a capability group.
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.

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.

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.

first candidate the host satisfies is resolved and its payload installed

The Vite build emitted path-absolute asset URLs (base: '/'). index.html
entry scripts and the favicon were rewritten to include the reverse-proxy
prefix in serveIndex, but two reference kinds are not in index.html and so
bypassed that rewrite:
- CSS `url()` font references (e.g. Font Awesome .woff2), which the browser
resolves relative to the stylesheet and which `<base href>` never affects
- lazily-imported route chunks, whose preload base came from the absolute
Vite base
Under a subpath mount (X-Forwarded-Prefix: /llm/) both were fetched from the
origin root, 404ing — missing-glyph "tofu" icons and broken lazy-loaded pages.
Switch Vite to a relative base ('./') so every generated URL resolves against
the file that references it: CSS fonts and route chunks now load from
`/llm/assets/...`, and index.html's now-relative entry refs resolve via the
`<base href>` serveIndex already injects on every response. Root deployments
are unaffected. The existing path-absolute rewrite in app.go still covers the
public `/favicon.svg`.

The managed-artifact materializer stages a HuggingFace snapshot into a
directory (.artifacts/huggingface/<key>/snapshot/). That is the right load
target for directory-consuming backends (transformers, vLLM, diffusers, ...),
but PrimaryArtifactSpec inferred a managed artifact from ANY HuggingFace-shaped
model reference regardless of backend. A single-file backend such as llama.cpp
or whisper was therefore handed the snapshot directory instead of the weight
file and failed to load it.
The /import-model importer already guards this with a backend allow-list
(managedArtifactBackends), but the loader-side inference did not. Move the
allow-list into core/config as IsManagedArtifactBackend and apply it in
PrimaryArtifactSpec: only directory-consuming backends may have an artifact
inferred from a bare reference; every other backend stays on the legacy
download-to-file path. An explicit artifacts: block still bypasses the gate,
where single-file snapshot resolution handles the load path.

fix(model-artifacts): load single-file HF snapshots from the file, not the dir
The managed Hugging Face artifact materializer (#10825) always pointed
backends at the snapshot *directory*
(.artifacts/huggingface/<key>/snapshot). For a single-file model
reference such as huggingface://nomic-ai/nomic-embed-text-v1.5-GGUF/nomic-embed-text-v1.5.f16.gguf,
the GGUF lives *inside* that directory, so llama.cpp was handed a
directory and failed with "gguf_init_from_reader: failed to read magic".
This has kept the tests-aio job red on master since the feature merged
(the embeddings e2e tests could not load text-embedding-ada-002).
Record the single file of a one-file snapshot as Resolved.PrimaryFile and
have ModelFileName() resolve to snapshot/<PrimaryFile> when it is set.
Multi-file snapshots (e.g. transformers repos consumed as a directory)
keep pointing at the snapshot directory. PrimaryFile is derived from the
resolved contents and is deliberately excluded from the artifact cache
key. estimateModelSizeBytes now derives the snapshot directory from the
cache key instead of ModelFileName(), so its manifest lookup is unaffected
by the file-vs-directory resolution.

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 +

carries it, and the config plumbing (draft_model + core/config/mtp.go)
was built for exactly this path, but no official Gemma 4 gallery entry
wired it up.
Add llama.cpp draft-mtp speculative-decoding variants for the dense

These replace the previously commented-out attempts, which were disabled
because the Janvitos/boxwrench drafter GGUFs declared the architecture as
`gemma4_assistant` (underscore) and failed to load on stock llama.cpp.
The unsloth drafters use the upstream `gemma4-assistant` (hyphen) spelling
that mtp.go's isDraftOnlyAssistantArch expects, so they load without any

reports no meaningful MTP speedup for it).
Also fix gemmable-4-12b-mtp: it loaded the draft-only `-mtp` GGUF as the
main model with no draft_model set, which cannot run standalone. It now
loads the target as the model, wires the drafter via draft_model, enables
spec_type:draft-mtp, and downloads both files.
All sha256 pins were taken from the HuggingFace API lfs.oid (reliable
content hash even for Xet-backed repos).

StopP2P() read and wrote a.p2pCtx/a.p2pCancel without holding
a.p2pMutex, and StartP2P() reassigned both fields with no lock at
all -- including when RestartP2P() calls it from a background
goroutine after releasing the mutex. Both paths are reachable from
POST /api/settings (empty p2p_token -> StopP2P, non-empty ->
RestartP2P), so concurrent requests race on the same fields.
Take a.p2pMutex in StopP2P and around the field publication in
StartP2P, factor the shared teardown into stopP2PLocked() so
RestartP2P reuses it, and route the goroutine error path through
StopP2P instead of touching a.p2pCancel unlocked.
