API Compatibility

All models work with both API endpoints:

  • POST /v1/chat/completions — OpenAI-compatible format
  • POST /v1/messages — Anthropic-compatible format

Use the same model ID in both APIs. For example, anthropic/claude-sonnet-4 works identically whether you call it via the OpenAI Chat Completions endpoint or the Anthropic Messages endpoint.
