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)
Model Provider Plugins
Each subdirectory is a self-contained provider profile plugin. The
directory layout mirrors plugins/platforms/:
plugins/model-providers/
├── openrouter/
│ ├── __init__.py # registers the ProviderProfile
│ └── plugin.yaml # manifest: name, kind, version, description
├── anthropic/
│ ├── __init__.py
│ └── plugin.yaml
└── ...
How discovery works
providers/__init__.py._discover_providers() scans this directory (and
$HERMES_HOME/plugins/model-providers/) the first time anything calls
get_provider_profile() or list_providers(). Each __init__.py is
imported and expected to call providers.register_provider(profile).
User plugins at $HERMES_HOME/plugins/model-providers/<name>/ override
bundled plugins of the same name — last-writer-wins in
register_provider(). Drop a file there to replace a built-in.
Adding a new provider
-
Create
plugins/model-providers/<your_provider>/__init__.py:from providers import register_provider from providers.base import ProviderProfile my_provider = ProviderProfile( name="your-provider", aliases=("alias1", "alias2"), display_name="Your Provider", description="One-line description shown in the setup picker", signup_url="https://your-provider.example.com/keys", env_vars=("YOUR_PROVIDER_API_KEY", "YOUR_PROVIDER_BASE_URL"), base_url="https://api.your-provider.example.com/v1", default_aux_model="your-cheap-model", ) register_provider(my_provider) -
Create
plugins/model-providers/<your_provider>/plugin.yaml:name: your-provider-profile kind: model-provider version: 1.0.0 description: Short sentence about the provider author: Your Name
Nothing else needs to change. auth.py, config.py, models.py,
doctor.py, model_metadata.py, runtime_provider.py, and the
chat_completions transport all auto-wire from the registry.
Non-trivial profiles
Override the ProviderProfile hooks in a subclass for per-provider
quirks — see plugins/model-providers/openrouter/__init__.py for
build_extra_body and build_api_kwargs_extras examples, and
plugins/model-providers/gemini/__init__.py for thinking_config
translation.
