An external-process provider is an agent CLI Hermes drives over stdio rather
than an HTTP endpoint. Three things about it were spelled out for one vendor,
and each was a hard stop for any other:
* ``resolve_provider()`` gates on ``PROVIDER_REGISTRY``. Its auto-extend from
``providers/`` covered api-key providers only, so an external-process profile
never entered it and ``hermes -m <that provider>`` died with "Unknown
provider" before a client was ever built.
* ``resolve_runtime_provider()`` keyed the external-process branch on the
literal ``"copilot-acp"``, so anything else silently fell through to the
OpenRouter default instead of its own runtime.
* ``resolve_external_process_provider_credentials()`` hardcoded the binary
(``copilot``), the argv (``--acp --stdio``), the env var names and the
placeholder api_key — so a third-party provider would have been handed
another vendor's CLI.
Now the profile carries what only the provider knows — ``process_command``,
``process_args``, ``process_command_env_vars``, ``process_args_env_var`` — and
the three core paths key on ``auth_type == "external_process"`` instead of a
name. copilot-acp's values move into its profile verbatim, so
``HERMES_COPILOT_ACP_COMMAND`` / ``COPILOT_CLI_PATH`` /
``HERMES_COPILOT_ACP_ARGS`` and its ``copilot-acp`` api_key placeholder behave
exactly as before; the new tests assert that alongside the out-of-tree case at
every step.
The error for a missing binary now names the provider and its own env override
instead of telling every user to install GitHub Copilot CLI.

``create_openai_client`` was a hardcoded if-ladder: copilot-acp builds an ACP
stdio shim, gemini builds a native client, everything else gets an
``openai.OpenAI``. There was no extension point, so a provider whose wire
protocol is not OpenAI-over-HTTP could only be added by editing this function —
which is exactly why an ACP provider cannot ship outside this tree today, even
though ``providers/__init__.py`` has discovered out-of-tree profiles from
``~/.hermes/plugins/model-providers/`` and pip entry points for a while.
``ProviderProfile.create_client(**client_kwargs)`` closes that gap. It returns
``None`` by default, so every provider that wants the standard client is
unaffected and the existing ladder still runs as the fallback. copilot-acp is
migrated onto it — its hardcoded branch is gone and its profile supplies the
client in three lines, which is the same three lines an external package writes.
Resolution goes by provider name first, then by ``base_url`` prefix, so a
runtime configured only by URL still reaches its profile — matching what the
replaced ``startswith("acp://copilot")`` branch did. A profile that raises is
logged and skipped: a third-party plugin can fail to provide a client, but it
cannot take the turn down.
Also replaces the two ``isinstance`` checks in ``agent/auxiliary_client.py``
that mean "this client is complete, do not wrap it" with capability flags the
client class declares — ``HERMES_SKIP_TRANSPORT_WRAP`` and
``HERMES_SKIP_ASYNC_WRAP``, mirroring ``SUPPORTS_HERMES_TOOL_CALLS`` in
``background_review.py``. Two in-tree consumers (the ACP shim and the Gemini
native client), an out-of-tree client is covered by the same declaration, and
the hot path no longer imports those modules just to type-test.

Slots above gemini-3.7-flash (kept) in OPENROUTER_MODELS and
_PROVIDER_MODELS["nous"]; openrouter plugin fallback_models bumped
3.7 -> 3.8; model-catalog.json regenerated.
Verified live with test completions on both Nous Portal and OpenRouter
(model echo + billed). Same 1,048,576 window / 65,536 output / pricing
as 3.7-flash, so provider-agnostic metadata resolves via the existing
gemini entries and both routes bill live (official_models_api) — no
pricing snapshot needed.
Scoped to the two named providers: vertex/gemini/kilocode/gmi curated
lists, setup.py samples, and aux defaults untouched.
- alibaba-coding-plan-cn / alibaba-token-plan-cn keep the shared intl key vars
as ordered fallbacks after their dedicated *_CN_API_KEY, so users who set
ALIBABA_CODING_PLAN_API_KEY / ALIBABA_TOKEN_PLAN_API_KEY for the CN endpoint
keep working (the PR as filed dropped them).
- list_authenticated_providers hides a '-cn' row whose only lit key vars are
ones it shares with its non-CN sibling, unless that CN provider is the
configured model.provider. With only the shared key: one row, not two;
DASHSCOPE_API_KEY alone: 3 alibaba rows, not 4.
- Docs: environment-variables.md, providers.md.
ALIBABA_CODING_PLAN_CN_API_KEY is checked first for the China Coding Plan
endpoint (mirroring kimi-coding-cn), so the intl and CN rows no longer
light off the same key. Fixes#101122.
Every conversation-affinity hint Hermes sends is derived from the PHYSICAL
session id: prompt_cache_key on both OpenAI-wire transports, OpenRouter's and
Nous Portal's sticky session_id, and xAI's x-grok-conv-id. A host that mints
one physical session per RESPONSE re-keys all four on every reply, so the
conversation never lands back on the routing bucket it just warmed (#96811).
Two hosts do exactly that. Hermes Studio's group chat mints
gc_run_<room>_<profile>_<name>_<uuid4hex> per reply and destroys it after,
and POST /v1/responses with client-managed history mints str(uuid4()) per
request — while parsing X-Hermes-Session-Key one screen earlier and handing
it to the agent.
Hermes must not infer the logical conversation from the id's syntax: that
rule merges independent client-supplied ids and Studio members truncated past
its 96-character boundary (the #79017 failure class). It does not have to.
gateway_session_key is already the "stable per-chat key" built by
gateway.session.build_session_key from that header, and branching
deliberately does not key off it. The affinity path simply never consulted it.
- agent/prompt_cache_scope.py: declared_conversation_scope() resolves the key
into gwk_<sha256[:24]> and outranks the lineage walk (it is stable across
rotation AND across per-response ids). Hashed because, unlike a session id,
the key embeds platform/chat/user identifiers and leaves the process
verbatim as a sticky id and as x-grok-conv-id.
- agent/portal_tags.py: a separate ambient scope for ROUTING, published only
when a host declared one. The providers read the attribution id when it is
unset, so delegate trees keep sharing their parent's sticky key and every
host that keeps one id per conversation is byte-identical to before.
- hermes_state.py: is_explicit_fork_child() — the public view of the marker
rules that keep /branch children, delegate subagents and tool children off
their parent's chat key. Background-review forks clone the live runtime, so
_persist_disabled excludes them for the same reason (#79161).
Refs #96570Fixes#96811
Sweeper review, all three points:
- Placement: no new plugins/model-providers/ directory. The Token Plan
profiles register from the existing alibaba plugin module — one module
per vendor, matching how the kimi module carries both of its endpoint
variants. Token Plan is the same vendor/service (Model Studio), same
OpenAI-compatible protocol, its own key + endpoints; splitting to a
standalone repo remains a 5-minute change if maintainers prefer.
- Runtime coverage: TestRuntimeAlibabaRegionalAndTokenPlan exercises
resolve_runtime_provider() for all four variants — provider, api_key,
api_mode, base_url — alongside the existing zai/minimax/kilocode
runtime regressions.
- Docs: providers.md, environment-variables.md, cli-commands.md updated
with the bundled variants and their env keys/base-url overrides.
The models.dev catalog advertises alibaba-cn, alibaba-coding-plan-cn, and
alibaba-token-plan(-cn), and resolve_provider_full()'s catalog chain lets
the CLI --provider path resolve them — but auth.resolve_provider() (the
credential/runtime path used by 'hermes chat') consults only
PROVIDER_REGISTRY and raised "Unknown provider 'alibaba-coding-plan-cn'"
(hermes_cli/auth.py:1937). PROVIDER_REGISTRY auto-extends from provider
profiles (auth.py:461-490), so the fix registers the missing profiles at
that chokepoint: alibaba-cn joins the alibaba plugin, alibaba-coding-plan-cn
joins alibaba-coding-plan, and a new alibaba-token-plan plugin registers
both regional token-plan tiers. Names match the catalog keys exactly.
No core edits — plugins/model-providers is the designed extension path.
The chat_completions and transport-parity Mistral tests pinned the
same branch with different reasoning_config shapes ({effort:none} vs
{enabled:False, effort:none}) — behaviorally identical since effort
short-circuits first, but the drift reads as a semantic difference.
Align both to the explicit form. Also scope the port-guard comment to
the try/except shape it actually shares with hermes_cli/models.py.
urlparse raises ValueError on non-integer / out-of-range ports, and
http://myhost:99999/v1 passes OpenAI-client construction (only httpx
rejects it later), so the crash was reachable from build_kwargs on
every request for such a URL. Wrap the parsed.port check in the same
try/except ValueError guard hermes_cli.models already uses around its
11434 check, and pin it with parametrized tests.
reasoning_effort: none was injecting extra_body.think=false for every
custom provider. Mistral (and other extra=forbid hosts) reject that
field with HTTP 422. Keep think=false on Ollama URLs only; still send
top-level reasoning_effort=none so /v1 thinking-off keeps working.
Review finding on salvaged #28253: the hand-rolled mapping sent
ultra -> medium while xhigh -> high (stronger request, weaker wire
value). Declare NEBIUS_EFFORTS in agent/reasoning_effort.py and use
clamp_effort like the zai/kimi/tokenhub call sites; disable detection
stays ahead of the clamp since clamp_effort('none', ...) returns the
floor, not off. Adds a monotonicity regression test.
Review findings on salvaged #93548: _warm_efforts_async now returns
early under PYTEST_CURRENT_TEST (matching the canonical OpenRouter caps
warmer) so a test that forgets to monkeypatch it can't fire live HTTP
when RAMP_ROUTER_API_KEY is set; the codex transport's fail-open
except in _profile_declared_efforts logs at debug instead of silently
swallowing profile-hook bugs.
Router shipped a minimal /v1/chat/completions compatibility surface
(translated onto Responses) after this PR was written, so the
'does not exist and 404s' wording is stale. Responses remains the
native wire — per-model reasoning-effort validation, reasoning
summaries, and prompt caching live there — so the api.router.com
host mandate is unchanged; only the comments and docs are updated.
Addresses the automated review on this PR:
- _profile_declared_efforts falls back from provider name to the
endpoint's host (via model_metadata's URL->provider map), so a named
custom provider pointed at api.router.com — which the host mandate
already routes onto this transport — gets the catalog clamp instead
of the default vocabulary and a Router 400.
- _parse_efforts validates catalog levels against EFFORT_LADDER at
ingest, logging and dropping unrecognized tiers; a model whose whole
vocabulary is unrecognized stays out of the map (transport defaults)
instead of passing the requested effort through unclamped.
- fetch_models dedupes ids while preserving Router's deliberate listing
order.
- plugin.yaml credits the human contributor per repo convention.
Router attributes coding-agent clients by User-Agent prefix (the way it
already recognizes OpenCode's versioned UA), and its WAF rejects
default/blank client UAs. Mirror the xai profile: declare
User-Agent: Hermes-Agent/<version> in default_headers, which
agent_init's profile-headers fallback applies at client construction.
Re-verified live: one-shot chat through api.router.com still works.
Ramp Router is an OpenAI Responses-compatible LLM gateway at
https://api.router.com/v1 that routes each request across upstream
providers (OpenAI, Anthropic, xAI, Fireworks, ...) with server-side
fallbacks and spend controls. Nous asked for a PR adding it as a
provider, so:
- plugins/model-providers/router/: RouterProfile plugin —
api_mode=codex_responses, RAMP_ROUTER_API_KEY auth,
RAMP_ROUTER_BASE_URL override, live account-scoped catalog via
GET /v1/models (no hardcoded fallback_models: IDs are key-scoped and
Router's docs mandate runtime catalog reads).
- hermes_cli/providers.host_mandated_api_mode +
runtime_provider._detect_api_mode_for_url: api.router.com ->
codex_responses. The host is Responses-only — POST /v1/chat/completions
does not exist and 404s — so this is a genuine host mandate (exact
hostname match per #32243, mirroring the api.meta.ai precedent).
- providers/base.py: new overrideable supported_reasoning_efforts(model)
hook (tri-state: None=defer, ()=model takes no reasoning params,
tuple=clamp set). Router validates reasoning.effort per model and
returns HTTP 400 invalid-argument on levels outside the model's
published vocabulary, and 400 unsupported_parameter when a
non-reasoning model receives any reasoning field (both verified live).
The profile answers from a cached copy of the catalog's
router.capabilities.reasoning block: cache-only on the hot path,
seeded for free by fetch_models(), disk-mirrored across processes
(/cache/router_catalog.json), background-warmed when cold
— same design as the OpenRouter reasoning-caps clamp on the chat path.
- agent/transports/codex.py: consult the profile-declared vocabulary in
the generic effort-clamp branch (xai/actual/github branches untouched;
profiles that do not override the hook see no behavior change).
- cli-config.yaml.example + adding-providers.md + providers/README.md:
document the provider, the host mandate, and the new hook.
- tests: behavior contracts for the host mandate/URL detection/spoof
rejection, profile registration + auth auto-registry wiring, catalog
parsing, and transport clamp/suppression/fallback paths.
Verified live against api.router.com (Aug 2026): one-shot chat,
streaming SSE, tool calls + parallel_tool_calls, encrypted-reasoning
replay on OpenAI-served models, function_call_output follow-up turns on
OpenAI- and Fireworks-served models; store:false / prompt_cache_key /
include:[reasoning.encrypted_content] / reasoning.summary accepted
across backends; effort clamp confirmed to convert a would-be 400
(xhigh on o3) into a successful request via the disk mirror.
GLM-5.3 accepts a graded low/medium/high/max reasoning_effort scale
(verified live in #91789: monotonic reasoning-token scaling, no 400s),
but the effort mapper reused GLM-5.2's two-level vocabulary, silently
rewriting low/medium to high. Adds GLM53_EFFORTS/GLM53_OVERRIDES and a
per-model vocabulary pick in the zai plugin; 5.2 keeps its high/max
clamp. Closes#91789. Also covers the gap noted when closing #86947
(credit @santhanakrishnan-d and @terje1965 for the graded-scale finding).
GLM-5.3 is live on api.z.ai (coding plan endpoint) but had no entries in
Hermes, so it silently fell back to the generic 202K GLM context —
triggering premature context compression on a 1M-window model.
- model_metadata: 'glm-5.3': 1_048_576 (same base model as 5.2; 1M
context / 128K max output per docs.z.ai/guides/llm/glm-5.3, verified
2026-08-14)
- auth: add glm-5.3 to coding-plan probe lists (global + CN)
- models: add glm-5.3 to picker/model lists (6 sites)
- zai provider: reasoning_effort mapping covers glm-5.3 (accepted live
by the endpoint, HTTP 200)
Live verification (2026-08-21): big-pickle and mimo-v2.5-free return 429
FreeUsageLimitError for ANY User-Agent except the opencode CLI's own
'opencode/latest' — same IP, no cooldown effect, while the other six free
models serve our honest HermesAgent UA freely. Hermes sends deliberate
attribution headers and does not impersonate other clients, so these two
models are broken for our users by policy on OpenCode's side; delist them
rather than ship dead picker entries.
- opencode-free catalog: 8 -> 6 models (both curated lists)
- plugin default_aux_model: big-pickle -> laguna-s-2.1-free (fastest
non-gated free model)
- keyless predicate keeps big-pickle (it IS free-tier; correct routing if
a user enters it manually — they get the relay's own 429, not our 401)
E2E: picker shows 6, laguna aux default completes a keyless agent turn.
Widens the salvaged #91323 fix (@vinsew): the effort vocabulary moves to
agent.reasoning_effort (OX_ALPHA_EFFORTS/OVERRIDES, the declared-policy
home every other model vocabulary lives in), and the translation is
shared between the opencode-zen profile and the keyless opencode-free
profile — Ox Alpha is reachable through both, and the free profile
previously dropped effort entirely.
Live-verified: medium clamps to low (raw medium 400s: 'This model always
engages in thinking... use low, high, or max'), xhigh rounds to max, and
full agent turns with effort=medium complete on BOTH providers.
OpenCode documents x-preview-f-free as accepting low, high, and max reasoning effort on its Zen Chat Completions endpoint. Hermes previously resolved the user's per-model override to max but the plain Zen provider profile discarded it, so successful calls silently ran at the server default.
Introduce an OpenCodeZenProfile scoped only to x-preview-f-free. It forwards the normalized top-level reasoning_effort, maps xhigh to max, preserves server defaults when unset or disabled, and leaves every other Zen model untouched.
Add profile and full transport tests that prove max reaches the outgoing request and that non-target models are unaffected. Also correct the nanoid security-pin comment to match the already-locked 3.3.18 release.
Reworks the salvaged OpenCode Free provider to match the tier's real
auth contract (verified live 2026-08-21): the Zen relay serves free
models ANONYMOUSLY and 401s any unrecognized bearer, so the provider now
declares no credentials at all and routes every model through the shared
keyless machinery from the Ox Alpha fix (empty Authorization default
header overriding the SDK bearer).
On top of the salvaged base:
- auth.py: no api_key_env_vars; drop the keyed-auth special case
- runtime_provider.py: restore the plain fail-closed path (opencode-free
never reaches it — the keyless runtime resolves first)
- models.py: opencode-free joins the opencode family (prefix stripping,
Zen endpoint routing incl. muse->responses); keyless predicate extended
with unsuffixed free slugs (big-pickle); free runtime pins EVERY
opencode-free model keyless; curated catalog replaces the models.dev
cost==0 filter (it lags reality: deepseek-v4-flash-free stayed 'free'
there after its promo ended and the relay began 401ing it — delisted)
- agent_runtime_helpers.py: replace the httpx transport-sharing auth-strip
wrapper with the shared header policy (no proxy-mount loss)
- model_setup_flows.py: skip the API-key prompt for opencode-free
- plugin profile: keyless headers, no env vars
- .env.example + providers.md: keyless docs (no OPENCODE_FREE_API_KEY)
- tests rewritten to the keyless contract, incl. catalog-membership
invariant (every curated model must satisfy the keyless predicate)
E2E: full AIAgent turns with zero keys complete on x-preview-f-free via
provider opencode-free and alias 'free', incl. a real terminal tool
round-trip; muse routes to /v1/responses; picker lists 8 keyless models.
Adds an OpenCode Free provider plugin. Free model discovery uses models.dev
(cost.input == 0 AND status != "deprecated"), matching opencode CLI's exact
filter logic.
The free tier requires a real account API key and throttles third-party
clients by User-Agent:
- With OPENCODE_FREE_API_KEY configured, the key is sent as a Bearer token
and requests identify as "opencode/latest".
- Without a key, the keyless fallback strips the SDK's always-injected empty
Authorization header and still sends the opencode User-Agent.
- The credential resolver no longer blanks OPENCODE_FREE_API_KEY
unconditionally (the stale keyless-tier assumption), and credential-pool
exhaustion no longer surfaces the misleading "Set OPENCODE_FREE_API_KEY"
message.

Both the wire path and the picker only consulted the catalog's
`mandatory` flag, so a route the Portal lists as accepting no reasoning
parameter at all still got sent a disable, and still offered a Thinking
toggle in the model picker.
For a route it serves, the aggregator's own catalog outranks the
models.dev inference: `supports_reasoning: false` now suppresses the
disable on the wire and drops reasoning controls from the picker
entirely, so there is no disable left to describe.
reasoning: {enabled: false} is the only shape the Portal honors, and the
profile refused to send it for every model. Sending nothing means the
upstream default instead, which on a thinking-first route like
deepseek/deepseek-v4-pro (catalog: default_effort high) is thinking ON — so
turning thinking off kept billing reasoning tokens on every turn.
The blanket omission was over-broad. The Portal only rejects a disable on
reasoning-mandatory routes ("Reasoning is mandatory for this model"), which
its catalog flags per model, so that flag now gates the omission. Models the
catalog can't speak to keep the old behavior rather than risk the 400.
extra_body.thinking, DeepSeek's own disable shape, is not forwarded upstream
by the Portal and is not an option here.
The #89503/#70058/#74295/#87279 bug class kept regenerating because every
transport and provider profile hand-rolled its own effort translation map
(9 sites, 4 distinct policies). New agent/reasoning_effort.py is the single
source of truth:
- EFFORT_LADDER: canonical low->high ordering (superset check against
VALID_REASONING_EFFORTS pinned by test)
- clamp_effort(): one policy — supported passes verbatim, otherwise nearest
WEAKER supported level (never escalate, never invert the ladder), floor
when nothing weaker, 'none' never a degradation target, declared
vendor-documented overrides win, bespoke names pass through
- declared wire vocabularies as data: OpenAI-compat, Codex Responses,
xAI (4.6/legacy), Actual relays, Kimi K3/K2, TokenHub, GLM-5.2,
DeepSeek V4, Ollama Cloud, Meta, Solar
Converted sites (all behavior-preserving except noted):
- chat_completions chokepoint, Kimi + TokenHub paths
- codex transport (backend branches now pick a declared set)
- auxiliary_client Responses path
- hermes_cli.models clamp_reasoning_effort_to_supported -> thin wrapper
- plugins: kimi-coding, zai, opencode-zen, deepseek, ollama-cloud,
meta-ai, upstage, custom (copilot already routes via the wrapper)
Behavior fixes the shared policy surfaces:
- ollama-cloud/opencode-go 'minimal' now degrades to 'low' instead of
being dropped (drop left the server default = MORE thinking than asked)
New tests: ladder contract (every configurable level is clamped by every
declared wire set; monotonicity across the full ladder for every set).
The chat_completions chokepoint fix (ultra->max for every model,
cherry-picked from #89509) has siblings with the same bug shape:
- codex.py: ultra->max was gated on gpt-5.6 only; now baseline for all
Responses-API models (backend-specific branches still override).
- Kimi top-level reasoning_effort: K3 accepts low/high/max only —
'medium' and upper-ladder levels were dropped to the medium default
(400s on K3, ladder inversion on K2). Full ladder mapped per family,
mirroring the kimi-coding plugin's K3 map.
- TokenHub: 'minimal' fell through to the 'high' default (asked least,
got most); full ladder now mapped onto low/medium/high.
- auxiliary_client Responses path: ultra->max alongside the existing
minimal->low clamp.
- custom provider plugin: ultra capped at max instead of forwarded
verbatim to GLM/vLLM/SGLang backends that reject it.
- copilot plugin: ad-hoc downgrade rules replaced with the shared
clamp_reasoning_effort_to_supported ladder walk so ultra/max resolve
to the strongest supported level instead of medium (#74295).
Sabotage-verified: new sibling-site tests fail 6/10 without the fixes.
Addresses the unresolved review comment on #30674 — avoid deep-copying
the whole conversation (including large tool outputs and attachments) to
sanitize two top-level keys on a handful of tool-role messages.
Switches to a shallow outer-list copy + shallow per-message dict copy,
applied only to messages that actually carry name/tool_name. Matches the
copy-on-write pattern already used by the shared sanitizer in
agent/transports/chat_completions.py and by QwenProfile.prepare_messages().
The needs_sanitize early-return path is preserved unchanged so the
existing identity check (prepare_messages returns the original list object
when nothing needs sanitizing) continues to hold.
Follow-up to the salvaged CommandCode signature fix: accepting base_url
but ignoring it left custom endpoints (user-configured model.base_url /
COMMANDCODE_BASE_URL proxies) fetching the public catalog instead of the
configured one. Reviewer dansigma flagged this on PR #88851.
Class-wide fix, not a CommandCode patch:
- providers/base.py: a caller base_url that DIFFERS from the profile's
default now wins over models_url. Equality with the default means "not
customised" (callers pass base_url unconditionally, defaulting to the
profile's own URL) and keeps models_url as the endpoint, preserving the
OpenRouter-style split-catalog behavior.
- commandcode: _fetch_commandcode_models() takes the endpoint override;
both profile overrides forward base_url.
- Tests: base-class precedence (custom beats models_url, default does
not), CommandCode redirect via live local HTTP server incl. claude-*
filter, and default-echo hitting the canonical endpoint. All verified
to fail against the pre-fix implementation (sabotage run).
The model picker's generic live-fetch path (hermes_cli/models.py
provider_model_ids) calls profile.fetch_models(api_key=..., base_url=...).
Both CommandCode overrides only accepted api_key/timeout, so every picker
open raised TypeError, which was silently swallowed, leaving the provider
with zero models.
Match the base ProviderProfile.fetch_models signature (base_url kwarg) and
add a regression test asserting both profiles accept it.
Reconciles the salvaged Responses-API mandate with the bundled meta-ai
plugin that landed in #88565:
- meta-ai profile api_mode -> codex_responses (prompt caching engages
only on /v1/responses; 0% vs 93-99% measured). Custom endpoints with a
non-api.meta.ai base URL still fall through to chat_completions via
the host-driven mandate design.
- cli-config.yaml.example: point the example at MODEL_API_KEY (Meta's
documented env var) and note the bundled provider covers the default
endpoint
- tests/providers/test_meta_ai_profile.py updated for the new wire
- plugins/model-providers/meta-ai/__init__.py: drop out-of-tree install
instructions from the module docstring (now bundled)
- tests/providers/test_meta_ai_profile.py: port the plugin's test suite
into the repo (registry discovery instead of file-location import)
- website/docs/integrations/providers.md: meta-ai in the first-class
API-key provider list, META_BASE_URL override, contributor-tier
data-training note
Ships the meta-ai provider profile from
albertodepaola/hermes-meta-provider as a bundled model-provider plugin:
OpenAI-compatible chat completions at https://api.meta.ai/v1,
MODEL_API_KEY auth, top-level reasoning_effort dial with the Meta
none->minimal 400 guard, vision support, 16k default max_tokens, and
muse-spark-1.2 / muse-spark-1.2-contributor as the offline fallback
catalog.
The provider-parity contract requires every CANONICAL provider to render a
card on the desktop Keys tab. /api/env rows are keyed by env var, and both
CommandCode profiles shared the single COMMANDCODE_API_KEY — so the
commandcode-anthropic profile had no row of its own and
test_provider_parity failed on CI (slice 6/12).
Fix: both profiles keep the shared API key, but each declares its own
base-URL override var (COMMANDCODE_BASE_URL / COMMANDCODE_ANTHROPIC_BASE_URL),
matching the sibling-provider pattern, so each renders its own card.
Verified: test_provider_parity.py + commandcode + providers suites green
locally (86 passed); PROVIDER_REGISTRY splits key vs base-URL vars correctly
for both profiles.
ActualProfile.fetch_models() overrides ProviderProfile's default
implementation with its own Actual-specific base_url resolution
(ACTUAL_BASE_URL env var, hosted-vs-local normalization), but called raw
urllib.request.urlopen(req, timeout=timeout) directly instead of the base
class's open_credentialed_url(). Every other provider either uses the
base class default or forwards to it via super() and gets
SafeCredentialRedirectHandler for free — Actual is the only provider that
attaches a Bearer token to its own Request object and opens it with the
stdlib's default redirect handling, which forwards every header,
including Authorization, across a cross-origin redirect.
Actual's own feature surface makes the trigger realistic: ACTUAL_BASE_URL
is a first-class, documented way to point this provider at a self-hosted
or local-offline endpoint (see the local-loopback no-auth path already
handled elsewhere in this provider), so a misconfigured or compromised
endpoint 302-ing to another host leaks ACTUAL_API_KEY to it.
Fix: import and call the same open_credentialed_url() the base class
uses, keeping Actual's own URL-resolution logic unchanged.
Adds an end-to-end regression test using two real local HTTP servers (no
mocking of the security module itself) — one redirects, the other
records the Authorization header it receives — mirroring
test_urllib_security.py's own redirect tests. Also repoints the existing
fetch_models test's mock from urllib.request.urlopen to
hermes_cli.urllib_security.open_credentialed_url, since fetch_models no
longer calls the former. Mutation-verified: the new redirect test fails
on pre-fix code with the Authorization header observed at the redirect
target.
Swaps the Google flash entry in the OpenRouter and Nous Portal curated
lists to the newly released gemini-3.7-flash (half the price of
3.6-flash: $0.375/M in, $1.875/M out per OpenRouter live metadata;
served on both endpoints, verified live). Also updates the OpenRouter
plugin fallback_models mirror and regenerates model-catalog.json.
Scoped to the two named providers: vertex/gemini/gmi curated lists and
aux defaults still carry 3.6-flash.
OpenCode identifies clients by request headers, the same way OpenRouter
does. Our opencode-zen and opencode-go profiles never set any, so every
request went out with the OpenAI SDK default "OpenAI/Python x.y.z"
User-Agent and OpenCode had no way to tell the traffic was Hermes Agent.
Two changes:
- Add HTTP-Referer, X-Title, and a HermesAgent User-Agent to both
OpenCode profiles through profile.default_headers, the same path
Fireworks uses. This covers chat_completions, codex_responses,
auxiliary clients, model switches, and the models catalog fetch.
- Merge the same headers in build_anthropic_client for opencode.ai
base URLs. The Anthropic Messages route (Claude on Zen, MiniMax and
Qwen on Go) builds its client there and never sees profile headers.
Verified against the live Go relay with a real key. Both wire formats
return HTTP 200 and the requests now carry X-Title "Hermes Agent",
HTTP-Referer, and User-Agent HermesAgent/0.20.0.
OpenRouter's /v1/models entries advertise reasoning capability
(supported_parameters + reasoning.mandatory/supported_efforts). Use that
metadata as the primary gate in _supports_reasoning_extra_body instead of
the hand-maintained vendor-prefix allowlist, which went stale one vendor at
a time (nvidia/ missing -> #75386). Also clamp the requested effort to the
nearest LOWER catalog-supported level in the OpenRouter profile so ultra/max
against a high-capped route no longer 4xxes.
Cache-only on the hot path: capabilities parse for free out of the existing
fetch_openrouter_models() payload, a background warmer covers cold starts,
and unknown models/offline catalogs fall back to the static prefix list
unchanged.
K3 only recognizes low/high/max. Previously the Kimi provider only
forwarded low/medium/high verbatim and dropped every other level
(xhigh/max/ultra/minimal) to the thinking toggle, silently ignoring
the user's requested effort.
Now maps the full Hermes vocabulary onto K3's set, matching K3's own
server-side mapping:
low, minimal → low
medium, high → high
xhigh, max, ultra → max

The Kimi team noticed that traffic from Hermes Coding Plan users
identifies itself as Claude (User-Agent: claude-code/0.1.0) rather
than the actual client. They asked us to update the UA so they can
properly attribute traffic and understand how their services are
accessed — especially important as they open up to more third-party
agents.
Three code paths were sending wrong/attribution-less headers to Kimi:
1. run_agent.py — _apply_client_headers_for_base_url sent
{"User-Agent": "claude-code/0.1.0"} for api.kimi.com. Now sends
the same _AI_GATEWAY_HEADERS set used for Vercel AI Gateway:
HTTP-Referer + X-Title + HermesAgent/{version} User-Agent.
2. agent/anthropic_adapter.py — the Anthropic Messages path for
api.kimi.com/coding sent 'claude-code/0.1.0'. Now sends the same
three-header attribution set.
3. plugins/model-providers/kimi-coding/__init__.py — both kimi and
kimi_cn profiles sent a static 'hermes-agent/1.0' with no
HTTP-Referer or X-Title. Now sends the full three-header set with
a dynamic version, matching the pattern used by the gmi, fireworks,
xai, and ai-gateway provider profiles.
The attribution header set (HTTP-Referer + X-Title + User-Agent) is
the canonical Hermes pattern used for OpenRouter, Vercel AI Gateway,
Fireworks, and other providers that read these headers for traffic
attribution.
