MiniMax Notes
  • Only Chat Completion endpoints are supported: MiniMax does not support the OpenAI Responses (/v1/responses) endpoint. Please use /v1/chat/completions or Anthropic /v1/messages.
  • Thinking field location: On the OpenAI endpoint, the reasoning chain is in choices[].message.reasoning_content; on the Anthropic endpoint, it appears as a thinking block in the content array.
  • Model name is case-sensitive: Use exactly MiniMax-M2.5 — both Ms capitalized — any other casing is rejected.
  • Do not pass reasoning in multi-turn context: When building conversation history, only pass back the previous turn's content (OpenAI) or text block (Anthropic) — do not include reasoning_content / thinking blocks in messages, otherwise a parameter error will be returned.
  • developer role not supported: The OpenAI compatible endpoint only accepts system / user / assistant roles.
