The remote model catalog (website/static/api/model-catalog.json) now labels
exactly one entry per provider block with "default": true — z-ai/glm-5.2 for
both OpenRouter and Nous Portal. That labeled entry is the model Hermes
silently lands on when the user never picked one, and it can be rotated by
editing the manifest alone: no release needed.
- model_catalog.py: get_default_model_from_cache() reads the label from the
in-process/disk cache only — never triggers a network fetch, so hot
resolution paths (agent build, gateway session setup) stay network-free.
- models.py: get_preferred_silent_default_model() resolves catalog label
first, PREFERRED_SILENT_DEFAULT_MODEL constant second (offline/fresh
install). _PROVIDER_SILENT_DEFAULT_OVERRIDES dict replaced by
_SILENT_DEFAULT_PROVIDERS routing through the shared resolver.
fetch_openrouter_models() preserves the "default" badge through live
/v1/models refreshes so the picker shows it.
- scripts/build_model_catalog.py: generator emits the default label so
regeneration can't drop it.
- website/docs/reference/model-catalog.md: schema documents the new field.
- Salvaged from PR #61141 (@HumphreySun98): bare-provider /model switches
(/model nous) route through the cost-safe default instead of curated
entry [0].
- tests: catalog-label precedence, constant fallback, stale-label fallback,
cache-only (no network) guarantee, and a shipped-manifest contract test
pinning the labeled entry to PREFERRED_SILENT_DEFAULT_MODEL.
E2E (temp HERMES_HOME): fresh-install constant fallback, shipped-manifest
label read, release-free rotation (relabeled cache -> new default across
models.py, tui_gateway, and gateway empty-model paths) all verified.
Rerun scripts/build_model_catalog.py so the manifest is source-generated
rather than hand-edited (the -pro rows from the cherry-picked #61587 were
already correct; only updated_at changes).
grok-4.5 is GA and is now the single curated Grok entry on the
aggregator lists. grok-4.3 is NOT retired upstream — it remains fully
usable by typing the model name (validated against the live catalogs);
this only removes it from the short curated picker snapshots. The
xAI-direct list is models.dev-cache-driven and unaffected.
* feat(xai): add grok-4.5 (early access) to catalog, context lengths, and reasoning-effort allowlist
- hermes_cli/models.py: grok-4.5 in _XAI_CURATED_EXTRAS (callable but absent
from models.dev) and _XAI_STATIC_FALLBACK, so the /model picker and
validation surface it on both xai and xai-oauth.
- agent/model_metadata.py: context lengths grok-4.5 -> 500K (per model card)
and grok-build-latest -> 500K (alias); grok-4.5 added to
_GROK_EFFORT_CAPABLE_PREFIXES.
Verified live against api.x.ai /v1/responses (2026-07-08): effort
low/medium/high accepted (server default: high), "none" rejected,
function calling works, full agent turn with terminal tool succeeded.
* feat(xai): grok-4.5 GA — add aggregator catalog entries, refresh comments
grok-4.5 is now GA: models.dev lists it (500K context, effort
low/medium/high) and both OpenRouter and Nous serve x-ai/grok-4.5.
Add it to the OpenRouter fallback snapshot and the Nous static list,
and update the early-access comments.
* chore: regenerate model-catalog.json for x-ai/grok-4.5
- OPENROUTER_MODELS: remove openrouter/owl-alpha (free) and
tencent/hy3-preview{,:free}; add tencent/hy3 and tencent/hy3:free
- _PROVIDER_MODELS[nous]: tencent/hy3-preview -> tencent/hy3
- run_agent.py reasoning-prefix list: tencent/hy3-preview -> tencent/hy3
(prefix match still covers -preview if pinned)
- model_metadata: register hy3 context length (262144) alongside hy3-preview
- regenerate website/static/api/model-catalog.json
- update tokenhub curated-list tests to the new IDs
The tencent-tokenhub direct provider still serves hy3-preview and is
intentionally unchanged.
- claude-fable-5 placed above claude-opus-4.8 in both curated lists
- claude-sonnet-5 replaces claude-sonnet-4.6
- sakana/fugu-ultra added near the bottom (before routers/free tier)
- regenerated website/static/api/model-catalog.json via scripts/build_model_catalog.py (live-pulled by CLI, published on merge — no release needed)
Z.ai released GLM 5.2 on 2026-06-15, available on OpenRouter:
- https://openrouter.ai/z-ai/glm-5.2
GLM-5.2 is Z.ai's flagship for long-horizon tasks, shipping a 1M-token
context window (up from 200K on GLM 5.1) and tool calling. Per the
OpenRouter API: text-only, context_length 1048576, tools supported.
No separate -fast variant exists.
The 1M context length, native zai picker entry, setup wizard, and Z.ai
coding-plan auth entries for glm-5.2 already landed on main. This fills
the remaining gap: the two aggregator surfaces where glm-5.1 appears but
glm-5.2 did not.
Changes:
hermes_cli/models.py
- Add z-ai/glm-5.2 to the OpenRouter fallback snapshot (OPENROUTER_MODELS)
and the Nous Portal curated list (_PROVIDER_MODELS["nous"]), newest
flagship first. Live catalogs surface it automatically when reachable;
the fallback lists matter when the manifest fetch fails.
website/static/api/model-catalog.json
- Regenerated via scripts/build_model_catalog.py (not hand-edited) so the
manifest stays in sync with the source lists; guarded by
tests/hermes_cli/test_model_catalog.py.
Adds the model above claude-opus-4.8 in both the OpenROUTER_MODELS and
_PROVIDER_MODELS['nous'] curated picker lists used by /model and
`hermes model`. Regenerated website/static/api/model-catalog.json to match.
Two new free-tier slugs surfaced in /model and `hermes model`. owl-alpha
was already present. Regenerated website/static/api/model-catalog.json to
keep the manifest sync test green.
Adds qwen/qwen3.7-plus directly under qwen/qwen3.7-max in both the
OpenRouter curated catalog (OPENROUTER_MODELS) and the Nous portal
catalog (_PROVIDER_MODELS['nous']), then regenerates the docs-hosted
model-catalog.json manifest from those source lists.
Two pre-existing failures on main, unrelated to each other:
- test_model_catalog: website/static/api/model-catalog.json was stale vs
_PROVIDER_MODELS — minimax/minimax-m2.7 was renamed to minimax/minimax-m3
without regenerating the committed manifest. Ran scripts/build_model_catalog.py.
- test_gui_command: the macOS relaunchable-signing fixup
(_desktop_macos_relaunchable_fixup) makes two subprocess.run calls (xattr +
codesign) on darwin before launch. The two darwin GUI tests set
sys.platform='darwin' and mock subprocess.run with a 2-element side_effect
(pack + launch), so the fixup's calls drained the iterator -> StopIteration.
Mock out the fixup in those two tests so the subprocess accounting stays
focused on pack/launch.
* feat(models): add deepseek-v4-flash to OpenRouter + Nous curated lists
deepseek/deepseek-v4-flash was already in the native deepseek provider
catalog but missing from the curated OpenRouter and Nous Portal picker
lists. Added it to both and regenerated the model-catalog.json manifest
(drift guard requires same-PR regeneration).
* refactor(models): trim redundant variants, group curated lists by maker
Remove claude-opus-4.7/4.6, gpt-5.4-nano, gpt-5.3-codex,
gemini-3-pro-image-preview, gemini-3.1-flash-lite-preview, grok-4.20,
and the older gemini-3-pro-preview (Nous). Reorder both OPENROUTER_MODELS
and _PROVIDER_MODELS[nous] into contiguous per-maker blocks with comment
headers. Regenerated model-catalog.json (openrouter 27, nous 20).
* feat(models): add gemini-3-pro-preview to OpenRouter + Nous curated lists
Adds google/gemini-3-pro-preview to both curated pickers (new on
OpenRouter, restored on Nous). Regenerated model-catalog.json
(openrouter 28, nous 21).
* test(models): use claude-opus-4.8 in OpenRouter fetch fixtures
The two TestFetchOpenRouterModels tests mocked a live OpenRouter
response with claude-opus-4.6 and relied on it surviving the curated-list
filter. Since 4.6 was removed from OPENROUTER_MODELS, those models got
filtered out and the recommended tag shifted. Swap the fixture to
claude-opus-4.8 (still curated, still first in the Anthropic block).
* chore(models): swap gemini-3-flash-preview for gemini-3.5-flash in OpenRouter + Nous lists
* chore(models): regenerate model-catalog.json for gemini-3.5-flash swap
The docs site (Vercel) serves /docs/api/model-catalog.json behind a bot
mitigation rule that returns HTTP 403 + x-vercel-mitigated: challenge for
non-browser User-Agents — including urllib (what the CLI uses) and curl.
When that happens, get_catalog() falls back to the stale disk cache and
new model releases (Opus 4.8, etc.) never reach the /model picker even
though they're already in OPENROUTER_MODELS and the live OpenRouter API.
Adds a fallback URL chain: when the primary catalog URL fails, walk
DEFAULT_CATALOG_FALLBACK_URLS — currently the raw.githubusercontent.com
copy of the same file. GitHub raw doesn't bot-gate, so the manifest stays
reachable through Vercel firewall hiccups. Per-provider override URLs
keep their direct-fetch semantics (operators configure those specifically,
no implicit fallback).
Also swaps stepfun/step-3.5-flash for stepfun/step-3.7-flash in the
OpenRouter + Nous Portal curated picker lists. Native stepfun provider
configuration (api.stepfun.ai) is left alone — that depends on what
stepfun.ai itself serves, not what OpenRouter routes.
Test plan: 5 new TestFallbackChain tests cover primary-success,
primary-failure-fallback-success, all-fail, primary==fallback-dedup, and
end-to-end get_catalog routing through the new helper. Existing 23 tests
in test_model_catalog.py still pass (28 total). Wider tests/hermes_cli/
sweep: 5701/5701 pass.
Anthropic released Claude Opus 4.8 on 2026-05-27, available on
OpenRouter, Anthropic, Amazon Bedrock, and Claude Platform on AWS:
- https://openrouter.ai/anthropic/claude-opus-4.8
- https://openrouter.ai/anthropic/claude-opus-4.8-fast
The fast-mode variant is a separate model ID (anthropic/claude-opus-4.8-fast)
priced at 2x of the base model — a notable improvement over the 6x premium
on older Opus generations (4.6/4.7). It is NOT a `speed: "fast"` request
parameter like Opus 4.6; Anthropic's native fast-mode beta still only
covers Opus 4.6.
Changes:
hermes_cli/models.py
- Add anthropic/claude-opus-4.8 + anthropic/claude-opus-4.8-fast to
the OpenRouter fallback snapshot and the Nous Portal curated list
(live catalogs surface them automatically when reachable; the
fallback list matters when the manifest fetch fails).
- Add claude-opus-4-8 to the Anthropic-native picker list.
agent/model_metadata.py
- Register claude-opus-4-8 / claude-opus-4.8 in DEFAULT_CONTEXT_LENGTHS
with 1M tokens (matches 4.6/4.7).
agent/anthropic_adapter.py
- Extend _XHIGH_EFFORT_SUBSTRINGS, _ADAPTIVE_THINKING_SUBSTRINGS, and
_NO_SAMPLING_PARAMS_SUBSTRINGS with "4-8"/"4.8". 4.8 inherits the
Opus 4.7 API contract: adaptive thinking only, xhigh effort level
supported, sampling parameters (temperature/top_p/top_k) return 400.
- Add claude-opus-4-8 to _ANTHROPIC_OUTPUT_LIMITS (128k max output,
same as 4.7). Matches by substring so claude-opus-4-8-fast and
date-stamped variants resolve correctly.
agent/usage_pricing.py
- Add anthropic/claude-opus-4-8: $5/$25 per MTok input/output, $0.50
cache read, $6.25 cache write (same as 4.6/4.7).
- Add anthropic/claude-opus-4-8-fast: $10/$50 per MTok (2x), $1.00
cache read, $12.50 cache write. Per OpenRouter, the 2x premium is
the only differentiator from regular Opus 4.8.
- OpenRouter routes still pull pricing from the live /models API, so
no static OpenRouter entry is needed.
tests/agent/test_model_metadata.py
- Extend the Claude 4.6+ context-length tag list with 4.8/4-8.
website/static/api/model-catalog.json
- Regenerated via `python scripts/build_model_catalog.py` to pick up
the new entries in the OpenRouter and Nous Portal fallback lists.
E2E verification (isolated sys.path import against the worktree):
- _supports_adaptive_thinking, _supports_xhigh_effort, _forbids_sampling_params
all return True for claude-opus-4.8 and claude-opus-4.8-fast.
- _supports_fast_mode (the `speed: "fast"` request-parameter gate) stays
False for 4.8 — fast mode is a separate model ID on OpenRouter, not a
parameter Anthropic accepts on the base model.
- DEFAULT_CONTEXT_LENGTHS resolves 1M for both notations.
- resolve_billing_route + _lookup_official_docs_pricing resolve the
correct $5/$25 (regular) and $10/$50 (fast) pricing for both
dot-notation and dash-notation inputs.
- 4.7 and 4.6 regression: behavior unchanged.
Unit tests: 305 passed across tests/agent/test_usage_pricing.py,
test_model_metadata.py, tests/hermes_cli/test_model_catalog.py,
test_models.py, test_model_validation.py, test_models_dev_preferred_merge.py.
Updates curated picker lists for both the OpenRouter fallback snapshot
(`OPENROUTER_MODELS`) and the Nous Portal list (`_PROVIDER_MODELS['nous']`).
Regenerates website/static/api/model-catalog.json via
`scripts/build_model_catalog.py` to keep the docs-hosted manifest in
sync (drift guard in `test_in_repo_lists_match_manifest`).
tests/hermes_cli/test_models.py fixtures updated — they pinned the
old model id as their live-fetch sample.
Add tencent/hy3-preview (without :free suffix) as a paid model route
alongside the existing free variant. This allows seamless transition
when the model moves from free to paid on OpenRouter — both routes
coexist so neither side's timing causes breakage.
Changes:
- models.py: add ("tencent/hy3-preview", "") to OPENROUTER_MODELS
- model-catalog.json: add paid variant entry
- tests: add assertions for paid route presence
The :free entry can be removed in a follow-up PR once OpenRouter
confirms the free route is deprecated.

Endpoint validated over 6 conversational turns with tool calls (9 API
calls, 3 tool calls, 0 failures) and an 8-request burst (8/8 ok,
0 rate limits). Latency ~5-10s/call — slower than grok-4.20 but
expected for a reasoning model.
- hermes_cli/models.py: add to OPENROUTER_MODELS and _PROVIDER_MODELS['nous']
- website/static/api/model-catalog.json: regenerated
Endpoint re-tested over 6 conversational turns (9 API calls, 3 tool calls)
and an 8-request burst — no rate limits, no errors, ~2-3s latency. The
historical rate-limit issues that caused its removal are gone.
- hermes_cli/models.py: add to OPENROUTER_MODELS and _PROVIDER_MODELS['nous']
- website/static/api/model-catalog.json: regenerated via build_model_catalog.py
OpenRouter and Nous Portal dropped the -beta suffix from the Grok 4.20 slug.
The OpenRouter section already used the new slug; this updates the Nous
Portal section and bumps updated_at.
Registers tencent-tokenhub (https://tokenhub.tencentmaas.com/v1) as a
new API-key provider with model tencent/hy3-preview (256K context).
- PROVIDER_REGISTRY entry + TOKENHUB_API_KEY / TOKENHUB_BASE_URL env vars
- Aliases: tencent, tokenhub, tencent-cloud, tencentmaas
- openai_chat transport with is_tokenhub branch for top-level
reasoning_effort (Hy3 is a reasoning model)
- tencent/hy3-preview:free added to OpenRouter curated list
- 60+ tests (provider registry, aliases, runtime resolution,
credentials, model catalog, URL mapping, context length)
- Docs: integrations/providers.md, environment-variables.md,
model-catalog.json
Author: simonweng <simonweng@tencent.com>
Salvaged from PR #16860 onto current main (resolved conflicts with
#16935 Azure Anthropic env-var hint tests and the --provider choices=
list removal in chat_parser).
Removes deepseek/deepseek-v4-pro and deepseek/deepseek-v4-flash from
OPENROUTER_MODELS and _PROVIDER_MODELS['nous'], then regenerates
website/static/api/model-catalog.json so the hosted picker JSON drops
them too. Direct-API deepseek provider support is unchanged.
OpenRouter and Nous Portal curated picker lists now resolve via a JSON
manifest served by the docs site, falling back to the in-repo snapshot
when unreachable. Lets us update model lists without shipping a release.
Live URL: https://hermes-agent.nousresearch.com/docs/api/model-catalog.json
(source at website/static/api/model-catalog.json; auto-deploys via the
existing deploy-site.yml GitHub Pages pipeline on every merge to main).
Schema (v1) carries id + optional description + free-form metadata at
manifest, provider, and model levels. Pricing and context length stay
live-fetched via existing machinery (/v1/models endpoints, models.dev).
Config (new model_catalog section, default enabled):
model_catalog.url master manifest URL
model_catalog.ttl_hours disk cache TTL (default 24h)
model_catalog.providers.<name>.url optional per-provider override
Fetch pipeline: in-process cache -> disk cache (fresh < TTL) -> HTTP
fetch -> disk-cache-on-failure fallback -> in-repo snapshot as last
resort. Never raises to callers; at worst returns the bundled list.
Changes:
- website/static/api/model-catalog.json initial manifest (35 OR + 31 Nous)
- scripts/build_model_catalog.py regenerator from in-repo lists
- hermes_cli/model_catalog.py fetch + validate + cache module
- hermes_cli/models.py fetch_openrouter_models() +
new get_curated_nous_model_ids()
- hermes_cli/main.py, hermes_cli/auth.py Nous flows use the helper
- hermes_cli/config.py model_catalog defaults
- website/docs/reference/model-catalog.md + sidebars.ts
- tests/hermes_cli/test_model_catalog.py 21 tests (validation, fetch
success/failure, accessors,
disabled, overrides, integration)
