Models

The caller supplies BYOK llm.providers and llm.models on create for OpenClaw and Hermes. Model-free AgentBay and BeeOS browser/mobile variants omit llm. See quickstart.

To use a different model, pass the Responses model field for that turn. A harness's default_model is set only when it is created; see harness management.

Never put model provider keys in browser or mobile code. See authentication and deployment.
