Model providers

Model providers are plugin profiles. They are discovered lazily the first time code calls get_provider_profile() or list_providers().

Location

Provider plugins live in:

plugins/model-providers/<name>/__init__.py

Each provider registers a ProviderProfile.

Discovery order

1. Bundled provider plugins.
2. User provider plugins under $ARCEN_HOME/plugins/model-providers/<name>.
3. Legacy files under providers/<name>.py.

User providers override bundled providers of the same name.

Supported examples

The README references OpenRouter, NovitaAI, NVIDIA NIM, Xiaomi MiMo, z.ai/GLM, Kimi/Moonshot, MiniMax, Hugging Face, OpenAI, Anthropic, LM Studio, Ollama, and OpenAI-compatible endpoints.
