Coze officially supports integrating custom models and provides three protocols: OpenAI Chat API, OpenAI Responses API, and Anthropic Messages API. The Base URL, path composition, Header, streaming, and tool-calling contracts differ across the three routes, so they must be configured and validated separately. “Experimental” means that the official capability and configuration entry have been confirmed, but different Coze regions, versions, or plans may display different forms. Ace Data Cloud still needs to complete fixed-version validation according to the protocol. Do not extrapolate the success of one protocol to the other two.

Configuration Principles

  • For the Base API URL, prioritize the base provided in the documentation; do not append endpoint paths that the client automatically completes again.
  • Use your Ace Data Cloud API Token as the API Key.
  • For Model, use the exact model ID in the model catalog that is compatible with the selected protocol.
  • After regular text succeeds, streaming and tool calling should also be validated.
