Model provider plugins can now declare per-model metadata (capability
booleans, context_window, model_family) through the existing
ProviderProfile registry using the canonical model_overrides schema.
Declarations patch catalog metadata without erasing unknown fields; on a
catalog miss, undeclared capability booleans stay unknown rather than
false.
Precedence (tested): explicit user model_overrides > plugin declarations
> catalog/builtin > _default fill-gap. lookup_models_dev_context shares
the same seam so auto-detected context reflects declarations, including
the dashboard /api/model/info response.
Provider aliases resolve declarations; user override lookup keeps its
existing provider-key rules. Metadata lookup may trigger the existing
lazy provider discovery (imports plugin code); the registry is
process-global and discovered once per process.
Progress on #102115.

Two independent gaps hit a user on provider opencode-go with
deepseek-v4-flash-vision-exp (#96066):
- Vision: the model is absent from models.dev, so get_model_capabilities()
returned None and image_input_mode: auto detoured images through the lossy
text describe path. OpenCode Zen/Go resell vendor previews before the catalog
indexes them; the id's `-vision` token is the vendor's own capability marker,
so _apply_overrides() now fills the catalog gap with a vision-only base for
any OpenCode-family provider (built-in or family-slug custom). Catalog entries,
explicit and _default overrides stay authoritative; reasoning stays unknown.
- Route: _resolve_agent_model_runtime() applied a resumed row's persisted
api_mode/base_url verbatim. A row written while the session ran an
anthropic_messages model (MiniMax on Go, or an older build's /zen/v1 relay)
pinned that wire onto a chat_completions model, surfacing as 401s from the
Anthropic transport or the Zen relay. Providers that pick the wire per model
(OpenCode families, Copilot, Nous — the existing _PROVIDER_API_MODE_OVERRIDES
table, now reachable via model_derived_api_mode()) re-derive api_mode from the
target model on resume and heal the relay URL; fixed-wire providers keep
honoring their row.
Salvages #96116 (@Finn763): same two atoms, redone slim (data-driven table
instead of an opencode-only hostname guard in the tui_gateway facade).
OpenCode's free tier now returns HTTP 403 for anonymous traffic outside
the OpenCode client, so the built-in keyless provider is dead weight:
- drop the opencode-free provider row, aliases (free/opencode_free), model
catalog, keyless runtime ladder rung, header wiring, and cached slugs
- delete the model-providers/opencode-free plugin
- update tests and the compat manifest for the removed symbols
- keep a migration hint in auth.py so users who had it configured see a
clear error naming the removal
Existing opencode-free configs can move to opencode-zen (pay-as-you-go)
or opencode-go (flat subscription).
Issue #112649 atom 4: a core (`_HERMES_CORE_TOOLS`) tool whose check_fn returns
False leaves neither the schema nor the tool_search catalog (it is not
deferrable), so the model's "no such tool" is accurate and nothing in the log
points at the probe. ae5666f7fc made the False verdict INFO for optional,
unconfigured toolsets — that stays; the core-tool drop is now a WARNING that
names the dropped tool(s), once per probe per process (the 30 s TTL re-probe
would otherwise re-warn every turn), reset by invalidate_check_fn_cache().
Review minor: `catalog_provider: deepsek` was accepted silently and the typo
leaked into ModelInfo.provider_id. An alias that is neither a Hermes provider
id nor a models.dev id (loaded catalog, no network) now warns once, mirroring
the unknown-key warning, and the row keeps its own slug.
A metadata-only model_overrides entry on a custom provider (only context_window set) took the
unknown-model branch of get_model_capabilities and reported max_output_tokens=8192 from the
_UNKNOWN_MODEL_BASE template; /model info showed "Max output: 8,192 tokens" for a model nobody
knows. The output limit is now left unknown (ModelCapabilities.max_output_tokens=None,
ModelInfo.max_output=0), matching the fail-open treatment #113146 gave supports_vision and
supports_reasoning. Consumers already handle a missing value: the dashboard only renders a
positive limit and the /model card only prints a truthy max_output.
There was also no way for a custom provider that resells a catalogued vendor's models (a
gateway/proxy) to reach _BUILTIN_MODEL_METADATA or the models.dev catalog, which is what forced
the metadata-only override in the first place. providers.<name>.catalog_provider (also honoured
on legacy custom_providers[] rows) names that vendor; models_dev resolves the catalog id through
it for capabilities, context, model info and provider info. It affects metadata lookups only,
never routing or credentials, and an explicit model_overrides entry still wins.
Closes the remaining atoms of #112649 (docs: providers page).
Background writers that still carry a tombstoned profile as their Hermes
home (reasoning-caps warm thread, models cache, models.dev ETag, gateway
lifecycle ledger, MCP OAuth tokens, memory store) re-created
profiles/<name>/ with a bare mkdir right before an atomic write. Route the
parent-dir creation through mkdir_under_hermes_home so a deleted named
profile raises FileNotFoundError and stays gone, matching the tombstone
contract already enforced for logging and state.
Extends the routing-variant fix to the sibling catalog paths, so the whole
bug class is covered rather than just context length (#97820).
_find_model_entry(), lookup_models_dev_context(), get_model_info(), and
get_model_capabilities() all keyed on the full suffixed id, so a routed id
such as z-ai/glm-5.3-flash:floor missed models.dev and fell through to the
generic "glm" family default (202,752 instead of 1,310,720).
The retry with the base id runs LAST — after exact and case-insensitive
matching — so a real catalog SKU always wins over its base.
:free and :batch are deliberately NOT stripped. They are real catalog SKUs,
not routing modifiers: OpenRouter's /models currently lists 18 :free and 65
:batch entries, and 13 of those carry a context window different from their
base (z-ai/glm-5.2:free is 256K vs the base's 1.05M). Stripping them would
report a window LARGER than the model has, so the request fails at the API
instead of merely compacting early — a worse failure than the under-report
this fixes. An absent SKU must also miss rather than inherit the base, so
model_overrides _default fill-gap semantics keep working.
The suffix set is shared from hermes_constants, so validation, context
resolution, and catalog lookup all agree on one definition.
Users on native DeepSeek were told to pin model.context_length and
model.supports_vision in config.yaml. That is the wrong layer: the 1M
window is already in DEFAULT_CONTEXT_LENGTHS, and a global
supports_vision pin would also mark text-only deepseek-v4-pro as
multimodal.
Two catalog gaps still produced the reported symptoms:
- A leftover context_length_cache.yaml entry of 128K (the old
``deepseek`` catch-all) outlived the 1M catalog keys because
deepseek-flash was missing from _PRE_CATALOG_STALE_KEYS.
- When models.dev is empty/cold, Flash has no capability record, so
image routing falls through to lossy text. Vendor docs (2026-09-10)
mark deepseek-flash as vision-capable and deepseek-v4-pro as not.
Discard those 128K leftovers, fill Flash (and retired Flash aliases)
via _BUILTIN_MODEL_METADATA, and leave Pro catalog-only.
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
opencode-free had no PROVIDER_TO_MODELS_DEV entry, so every models.dev
lookup on the free tier missed and Muse Spark fell to the 256K default.
The free tier is served by the Zen relay (hermes_cli/models.py:
"opencode-free is Zen-hosted"), and models.dev's "opencode" provider is
the catalog that lists muse-spark-1.2 / -1.2-contributor-free /
-1.3-contributor-free at 1,048,576 — so the alias is "opencode", not
"opencode-go" (Go's catalog carries only the paid -contributor SKUs).
Missing alias identified by @Steve-prog001 in #101905.
Tests: one parametrized offline invariant (models.dev + live /models
mocked away) asserting 1,048,576 on opencode-free / opencode-go /
meta-ai / commandcode — fails on main, passes here — plus the alias pin.
- Cold force_refresh (fresh CLI process, e.g. hermes config refresh)
now hydrates the memory cache from disk before fetching, so the
conditional GET actually fires on the flow the feature was built for
instead of silently re-downloading the full ~2 MB registry
(empirically probed: If-None-Match sent, 304 serves disk data).
- Conditional-GET decision is passed in explicitly
(_fetch_models_dev_from_network(conditional=...)) by callers holding
the fetch lock, removing the hidden read of module globals inside
the fetch; the background worker now fetches INSIDE the lock,
symmetric with foreground (true singleflight — no concurrent
double-download, no fetching against mid-commit etag state).
- Corrupt disk cache is QUARANTINED (renamed to .json.corrupt) rather
than left in place: rejection becomes a one-time event instead of a
re-read + re-parse + warning + unlink on every hot-path call while
offline (probed: 1 warning across 5 calls, was 5).
- Dropped the dead _DEFAULT_MODELS_DEV_URL constant; module and
function docstrings updated to match the servable-cache conditional
semantics.
- Conditional GET now requires a servable in-memory registry: an
If-None-Match sent while holding no cache invited a 304 against
nothing, permanently serving {} with a blocking foreground fetch on
every call (the exact #35838 class this PR fixes). Empirically
repro'd and verified fixed (corrupt cache + stale sidecar: was 3
calls -> {} forever; now 1 unconditional fetch -> real data).
- ETag persists atomically WITH the cache body via
_commit_registry -> _save_disk_cache(data, etag), wiring up the
previously-dead etag param; the sidecar can no longer get ahead of
the registry it vouches for. _save_etag now uses
utils.atomic_write_text (unique tempnames + fsync) instead of a
hand-rolled fixed-name .tmp replace.
- Corrupt/unreadable disk cache clears the ETag sidecar so the
refetch is unconditional; _confirm_cache_not_modified keeps a
defense-in-depth guard (clear sidecar + arm backoff) should a 304
ever land on an empty registry.
- allow_network=True paths use the zero-arg fetch_models_dev() call
shape at all sites (was 1 of 5) — ~46 test sites monkeypatch it
with zero-arg lambdas; the unconditional kwarg broke
test_xiaomi_provider (verified fail->pass).
- _get_models_dev_url falls back to the MODELS_DEV_URL module global
(not the constant) so existing patch sites keep working.
- Tests: replaced two mock-riddled corrupt-cache tests with real
tmp_path file tests; added regression tests for the 304/empty-cache
loop, sidecar clearing, and conditional-GET gating.
Harden the models.dev catalog refresh path (#35838) with three missing
pieces:
1. ETag conditional GET — every network request sends If-None-Match
with the last-known ETag (persisted alongside the cache file). A 304
Not Modified re-confirms the existing cache without re-downloading
the full ~2 MB registry. This makes the 4-hour TTL effectively free
to maintain.
2. No-network-on-hot-paths invariant — allow_network=False is now the
default for every query function called on the conversation hot path:
get_model_capabilities, get_model_info, lookup_models_dev_context,
_get_provider_models. These are called during vision routing, image
routing, cost-guard checks, and context-length resolution on every
turn — they must never block on the network. Interactive flows
(model picker, model switch) explicitly pass allow_network=True.
3. Mirror URL override — models_dev.url in config.yaml lets deployments
point at a self-hosted mirror without code changes. Follows the same
pattern as model_catalog.url.
Additional hardening:
- Cache TTL bumped from 1h to 4h (ETag makes refresh cheap)
- Corrupt/empty disk cache is rejected with a warning instead of being
served as {} and silently breaking provider/model resolution
- _validate_registry() guards against non-dict and empty-dict payloads
Fixes#35838
- Deleted the id(cfg)-keyed _OVERRIDE_CACHE layer: id() is unique only
among live objects, so a config reload could serve stale overrides
forever when CPython reuses the freed dict's address. The upstream
load_config_readonly is already (mtime,size)-cached (~1 stat/hit), so
the local layer was redundant state with a correctness risk.
- _override_to_catalog_shape returns (patch, vision) instead of
smuggling an in-band _vision_override sentinel key through the merged
dict; removed the two dead call-site pops.
- _find_model_entry gains the :cloud/-cloud suffix fallback that
lookup_models_dev_context already had, so 'catalog hit' means the
same thing to every consumer — a suffix-keyed model (kimi-k2.6:cloud)
now counts as KNOWN and keeps its catalog capabilities instead of
being displaced by a fill-gap _default (mutation-checked contract
test added).
- get_model_info's unknown-model override path seeds the same safe
defaults as get_model_capabilities (200K ctx, tools on, 8192 out),
so a partial override no longer yields ctx=0/tools-off on that path
(contract test added); the DEFAULT_CONFIG defaults claim is now true
for both paths.
- Activated the previously-dead _MODELS_DEV_TO_PROVIDER reverse map
(lazily built, many-to-one aware) and used it in
_provider_override_section instead of a per-call linear scan.
Review follow-ups on the model_overrides feature:
- ONE canonical override schema everywhere. get_model_info previously
merged the override dict raw into the models.dev catalog shape
({**raw, **override}), so the documented context_window/supports_*
keys silently did nothing on that path (cost guard, inventory) while
working in capabilities/context paths — same config key, two
incompatible schemas. Overrides are now translated into the catalog
shape at the get_model_info boundary (_override_to_catalog_shape),
and sub-dicts (limit, modalities) are MERGED, not clobbered — an
override setting only context_window no longer wipes the catalog's
limit.output.
- _default is now a FILL-GAP default, not an override: it applies only
to models the catalog does not know (the #8731/#84482 self-unblock
path) and never displaces catalog data. A
_default: {context_window: 128000} can no longer clamp every model
of a provider. Explicit per-provider+model entries keep their
win-over-catalog semantics.
- Early-chain _override_context_window (model_metadata step 0b) is
explicit-only, so a _default can never preempt custom_providers
per-model settings or live probes; fill-gap defaults apply at the
lookup_models_dev_context catalog-miss boundary (step 5f) instead.
This fixes the precedence inversion where a provider/global _default
silently overrode an explicit per-endpoint per-model context_length.
- Provider keys accept BOTH id spaces (Hermes id and models.dev id:
copilot/github-copilot both work) and model ids match
case-insensitively, mirroring catalog lookup.
- Malformed override values (context_window: '512k') log a one-shot
warning instead of being silently swallowed.
- DEFAULT_CONFIG comment: removed the false family/dated-snapshot
inheritance claim, documented the recognized field list, fill-gap
semantics, and the id-space rule.
- Tests: rewritten for the new contracts (fill-gap invariants,
dual-id-space keys, sub-dict merge preservation, one-shot warning);
added a real-config-yaml e2e plumbing test (mutation-checked: fails
when the config key wiring is broken).
Add a unified model_overrides config section that lets users manually
declare context_window, max_output_tokens, capabilities, cost, and
family for any provider+model — winning over models.dev, OpenRouter, and
hardcoded defaults.
Resolution order (first hit wins):
1. model_overrides.<provider>.<model_id> (per-provider+model)
2. model_overrides.<provider>._default (per-provider default)
3. model_overrides._default (global default)
4. Normal catalog resolution
Key subtlety: an unknown model id (not in the
catalog) derives base metadata from sensible defaults before patching,
so overriding a model the catalog doesn't know yet is the supported
self-unblock path. This is exactly the #84482 scenario (Upstage
solar-pro4/syn-pro wrong context) and the #8731 scenario (custom/local
models with manual capability declaration).
Wired into:
- get_model_capabilities() — patches capability fields; unknown models
get safe defaults (tools on, vision/reasoning off) before patching
- lookup_models_dev_context() — context_window override, checked before
catalog lookup so it works even for providers not in PROVIDER_TO_MODELS_DEV
- get_model_info() — merges override dict onto catalog entry (shallow
merge); for unknown models, the override is the sole source of metadata
- get_model_context_length() — step 0b in the resolution pipeline,
before custom_providers (0c) and before any network probe

* fix(models_dev): map meta-ai provider to models.dev 'meta' id
Muse Spark models (muse-spark-1.1/1.2/-contributor) are served via the Meta
Model API and reverse-map from api.meta.ai to the Hermes provider id 'meta-ai'.
models.dev keys the same models under the provider id 'meta'.
lookup_models_dev_context() / _get_provider_models() resolve the models.dev id
strictly via PROVIDER_TO_MODELS_DEV.get(provider) (no raw-id fallback, unlike
get_model_info()), so an unmapped 'meta-ai' missed entirely and context fell
back to the generic 256K default instead of the true ~1M window. Add the
meta-ai->meta mapping (plus a defensive meta->meta) so context and pricing
resolve from models.dev: 1.1=1,000,000; 1.2 & -contributor=1,048,576.

Local-model users paid a fresh probe waterfall on EVERY CLI cold start
inside AIAgent.__init__: detect_local_server_type (up to 4 HTTP GETs,
2s timeout each on a hung server) + /api/show (3s timeout). The
existing caches were in-process only, so back-to-back invocations
(chat -q, cron ticks, subagents) re-paid the network every time.
- New 300s-TTL disk L2 at HERMES_HOME/cache/local_endpoint_probes.json
for detect_local_server_type verdicts and query_ollama_num_ctx
results. Only SUCCESSFUL probes persist (a down server never pins a
negative verdict); stale entries pruned on write; corrupted cache
degrades to a miss; atomic writes. 300s is strictly fresher than the
1h in-process TTL that already accepts server-swap staleness.
- models.dev fetch timeout 15 -> (5, 10) connect/read tuple: a
blackholed connect stalled the first-turn critical path 15s; now
fails in 5s (matches the OpenRouter fetch convention, #46620).
- _auto_detect_local_model timeout 5 -> (2, 3): runs inside
_get_model_config() at startup against a LOCAL endpoint; a hung local
server cost 5s before the banner.
E2E (real HTTP server, two fresh subprocesses, isolated HERMES_HOME):
proc1 = 2 HTTP hits, proc2 = 0 HTTP hits, identical results
(ollama/131072), probe wall 74.5 -> 35.5 ms. 222 targeted tests green
incl. 9 new disk-L2 contract tests.
- extract _commit_registry/_note_refresh_failure shared by the background
worker and foreground stage-4 (identical 4-step success + failure paths
were duplicated); worker now commits under _models_dev_fetch_lock so a
failing background refresh can never re-arm the backoff immediately
after a successful force_refresh committed (unsynchronized-write race)
- add should_clear_context_pin_async to hermes_cli/route_identity.py
(matching the get_model_context_length_async precedent) and use it at
the 4 async gateway sites instead of inline asyncio.to_thread wraps;
the sync _format_session_info site keeps the sync call (already
off-loop via its callers' to_thread)
- test the background-refresh success path (the PR's primary new
behavior): disk saved, mem cache swapped, backoff cleared, in_flight
reset — mutation-checked
- replace the race-prone spin-wait on _models_dev_refresh_in_flight with
a named-thread join in the backoff test
The branched call shape in get_provider_info/get_provider is deliberate:
~69 test sites across tests/hermes_cli and tests/gateway monkeypatch
fetch_models_dev (and get_provider_info) with zero/single-arg lambdas.
Passing allow_network= unconditionally broke 5 tests in CI slices 2/3/7.
Documented the constraint inline.
- _mark_stale_cache_grace only moves cache_time forward so a completed
background refresh is never rewound to a 5-minute grace window
- clear _models_dev_refresh_in_flight if Thread.start() raises so a
one-off thread-exhaustion failure doesn't disable refresh forever
- move empty-registry validation into _fetch_models_dev_from_network
(was duplicated in the background worker and the foreground fetch)
- pass allow_network through as a plain kwarg in get_provider_info and
hermes_cli.providers.get_provider instead of the branched call shape
- refresh the stale module docstring (no bundled snapshot exists; the
resolution order now describes stale-serve + background refresh)
* remove Vercel AI Gateway provider and Vercel Sandbox terminal backend
Both Vercel-hosted integrations are removed end-to-end. Users on the AI
Gateway should switch to OpenRouter or one of the other aggregators
(Nous Portal, Kilo Code). Users on the Vercel Sandbox backend should
switch to Docker, Modal, Daytona, or SSH.
What's removed:
- `plugins/model-providers/ai-gateway/` provider plugin
- `hermes_cli/vercel_auth.py` Vercel-Sandbox auth helper
- `tools/environments/vercel_sandbox.py` terminal backend
- `ai-gateway` provider wiring across auth, doctor, setup, models,
config, status, providers, main, web_server, model_normalize, dump
- `vercel_sandbox` backend wiring across terminal_tool, file_tools,
code_execution_tool, file_operations, approval, skills_tool,
environments/local, credential_files, lazy_deps, prompt_builder,
cli, gateway/run
- `AI_GATEWAY_BASE_URL` constant, `_AI_GATEWAY_HEADERS` auxiliary-client
header set, run_agent base-URL header/reasoning special-cases
- `[vercel]` pyproject extra and `vercel`/`vercel-workers` from uv.lock
- env vars: `AI_GATEWAY_API_KEY`, `AI_GATEWAY_BASE_URL`, `VERCEL_TOKEN`,
`VERCEL_PROJECT_ID`, `VERCEL_TEAM_ID`, `VERCEL_OIDC_TOKEN`,
`TERMINAL_VERCEL_RUNTIME`
- Tests: deletes test_ai_gateway_models.py and
test_vercel_sandbox_environment.py; scrubs references across 23
surviving test files (no entire tests deleted unless they were
dedicated to AI Gateway / Sandbox)
- Docs: provider tables, env-var reference, setup guides, security
notes, tool config, terminal-backend tables — English plus zh-Hans
i18n parity
- `hermes-agent` skill: provider table entry and remote-backend list
What stays (intentional):
- `popular-web-designs/templates/vercel.md` — CSS design reference,
unrelated to Vercel-the-AI-product
- `x-vercel-id` in `stream_diag.py` headers — generic Vercel CDN
response header, useful diag signal on any Vercel-hosted endpoint
- `vercel-labs/agent-browser` URL in browser config — lightpanda
browser project, different OSS effort
- `userStories.json` historical contributor entry mentioning Vercel
Sandbox — archive, not active docs
Validation:
- 1153 tests in the 22 targeted files pass (`scripts/run_tests.sh`)
- Full repo `py_compile` clean
- Live import of every touched module + invariant check (no
`ai-gateway` in `PROVIDER_REGISTRY`, no `_AI_GATEWAY_HEADERS`, no
`vercel_sandbox` in `_REMOTE_TERMINAL_BACKENDS`)
* test: convert profile-count check from change-detector to invariant
The hardcoded "== 34" assertion broke when ai-gateway was removed.
Per AGENTS.md change-detector-test guidance, assert the relationship
(registry count >= number of plugin dirs) instead of a literal count.
Counts shift when providers are added/removed; that's expected.
Add NovitaAI as a first-class provider with dedicated model selection
flow, live pricing, and authoritative context length resolution.
- Register provider in PROVIDER_REGISTRY, HERMES_OVERLAYS, and all
alias/label maps (ID: novita, aliases: novita-ai, novitaai)
- Add dedicated _model_flow_novita() with 3-tier model list fallback:
Novita API → models.dev → static curated list
- Fetch live pricing from /v1/models with correct unit conversion
(input_token_price_per_m is 0.0001 USD per Mtok)
- Add Novita-specific context length resolution (step 4b) in
get_model_context_length(), prioritized over models.dev/OpenRouter
- Register api.novita.ai in _URL_TO_PROVIDER to prevent early return
from the custom-endpoint code path
- Add models.dev mapping (novita → novita-ai)
- Add default auxiliary model (deepseek/deepseek-v3-0324)
- Add NOVITA_API_KEY to test isolation (conftest.py)
- Update docs: providers page, env vars reference, CLI reference,
.env.example, README, and landing page
Based on PR #23950 by @nicoechaniz.
- Add "kimi" and "moonshot" to PROVIDER_TO_MODELS_DEV → kimi-for-coding
- Gate OpenRouter metadata step behind "if not effective_provider":
known providers should not be overridden by community-maintained OR data
- Keep the targeted Kimi-family 32k guard as a secondary safety net
inside the OR gate (for unknown providers with Kimi models)
Co-authored-by: nicoechaniz <nicoechaniz@altermundi.net>
Kimi-k2.6 (which supports 262K context) was incorrectly resolved as 32K,
tripping the 64K minimum-context guard and preventing use of the model on
Ollama Cloud and Kimi Coding / Moonshot providers.
Three fixes in the context-length resolution chain:
1. Ollama Cloud native /api/show query: new _query_ollama_api_show()
queries the Ollama native API for authoritative GGUF model_info
context_length. For hosted Ollama, prefers model_info over num_ctx
since users can't set their own num_ctx on Cloud. Added at step 5e
in get_model_context_length(), before the models.dev fallback.
2. models.dev :cloud/-cloud suffix fallback: lookup_models_dev_context()
now also tries appending :cloud and -cloud suffixes when the bare
model name doesn't match. models.dev stores 'kimi-k2.6:cloud' but
users and the live API use bare 'kimi-k2.6'.
3. Kimi-family 32K guard: after the OpenRouter metadata step, reject
exactly 32768 for Kimi-named models (kimi-*, moonshot*) and fall
through to hardcoded defaults ('kimi': 262144). OpenRouter reports
32768 for moonshotai/kimi-k2.6 but the model actually supports 262K.
Narrow filter — only 32768, only Kimi-family — becomes dead code
when OpenRouter updates its metadata.
---
`fetch_models_dev()` is on the hot path of every `AIAgent.__init__`
(via `context_compressor → get_model_context_length`). The previous
policy was "always try network first, only fall back to disk if
network fails," so every fresh `hermes chat` / `hermes gateway` /
batch / cron process paid 250-500 ms re-fetching a 2 MB JSON registry
that was already on disk from earlier runs.
Add a stage 2 between in-mem and network: if
`models_dev_cache.json` exists and its mtime is younger than the
existing `_MODELS_DEV_CACHE_TTL` (1 hour, same TTL the in-mem cache
already uses), load from disk and skip the network call.
The in-mem TTL is anchored to the disk file's age, so a 50-min-old
cache stays in-memory for only 10 more minutes — no surprise
extension of staleness window.
Invariants preserved:
- `force_refresh=True` still always hits the network and only falls
back to disk on failure (`hermes config refresh` semantics).
- Missing disk cache → fall through to network (first-ever run).
- Stale disk cache (mtime > TTL) → fall through to network.
- Negative file age (clock skew) → fall through to network.
- Network failure → existing stage-4 stale-disk fallback unchanged.
Measured impact (3-run medians, 9950X3D, fresh process per run):
fetch_models_dev cold: 256 → 17 ms (-93%)
hermes chat -q wall: 4.00 → 3.73 s (-7% median)
3.99 → 3.60 s (-10% min)
The chat-end-to-end win is bounded below by API latency variance, but
the fetch_models_dev microbenchmark is the cleanest signal: 239 ms
shaved off every fresh-process agent construction.
Win compounds with the previous perf PRs:
#22681 google_chat lazy-load
#22766 doctor parallel + IMDS off
#22790 gateway.platforms PEP 562
Tests: all 30 `tests/agent/test_models_dev.py` pass (added 4 new ones
covering the new disk-cache-first path, force_refresh override, stale
disk fallback, and missing-disk-cache fall-through). Full `tests/agent/`
suite: 2560 passed, 0 failed.
Close integration gaps discovered by auditing qwen-oauth's file coverage.
These are surfaces the original salvage missed — they all existed on
main and were added in the 747 commits since PR #15203 was opened.
Coverage added:
- agent/credential_pool.py: seed pool from auth.json providers.minimax-oauth
so `hermes auth list` reflects logged-in state and
`hermes auth remove minimax-oauth <N>` works through the standard flow.
- agent/credential_sources.py: register RemovalStep for minimax-oauth
with suppression-aware `_clear_auth_store_provider`.
- agent/models_dev.py: PROVIDER_TO_MODELS_DEV mapping (-> 'minimax' family).
- hermes_cli/providers.py: HermesOverlay entry (anthropic_messages transport,
oauth_external auth_type, api.minimax.io/anthropic base).
- hermes_cli/model_normalize.py: add to _MATCHING_PREFIX_STRIP_PROVIDERS so
`minimax-oauth/MiniMax-M2.7` in config.yaml gets correctly repaired.
- hermes_cli/status.py: render MiniMax OAuth block in `hermes doctor`
(logged-in / region / expires_at / error).
- hermes_cli/web_server.py: register in OAUTH_PROVIDER_REGISTRY + dispatch
branch in _resolve_provider_status so the dashboard auth page shows it.
- website/docs/integrations/providers.md: full 'MiniMax (OAuth)' section.
- website/docs/reference/cli-commands.md: --provider enum.
- website/docs/user-guide/features/fallback-providers.md: fallback table row.
- scripts/release.py AUTHOR_MAP: amanning3390 mapping (CI gate).
Adds a first-class 'stepfun' API-key provider surfaced as Step Plan:
- Support Step Plan setup for both International and China regions
- Discover Step Plan models live from /step_plan/v1/models, with a
small coding-focused fallback catalog when discovery is unavailable
- Thread StepFun through provider metadata, setup persistence, status
and doctor output, auxiliary routing, and model normalization
- Add tests for provider resolution, model validation, metadata
mapping, and StepFun region/model persistence
