Use your 678API API key.

Tip

Name the provider clearly, for example 678API GPT or 678API Claude, to avoid selecting the wrong provider.

Common questions

  • You do not need to sign out of Trae; the account and custom model provider have separate roles.
  • If Chat works but completion does not, check the provider selected for each feature.
  • Only append /chat/completions when the field explicitly requests a full endpoint rather than a Base URL.
  • To restore the built-in service, select an official model and disable the 678API provider.
