这个API变更直接影响使用小米MiMo模型的智能体开发者，尤其是多轮对话场景。如果你在用TRAE、Cursor等框架集成MiMo，建议立即检查代码，避免因缺失推理内容导致400错误和体验降级。
小米MiMo团队发布警告，使用思考模式进行多轮智能体对话时，若历史记录包含工具调用，后续用户回合必须保留完整推理内容字段，否则API会返回400错误。缺失推理内容会导致上下文不完整，降低指令遵循能力、增加幻觉并影响用户体验。受影响的框架包括TRAE、Cursor、Roo Code、Codex、GitHub Copilot CLI、Zed和AutoGen，团队正与维护者合作推动兼容更新。涉及模型包括MiMo-V2.5-Pro、MiMo-V2.5、MiMo-V2-Pro、MiMo-V2-Omni和MiMo-V2-Flash。
Heads up, agent users！ If you're using Xiaomi MiM…
Heads up, agent users！
If you're using Xiaomi MiMo with thinking mode: When thinking mode is enabled in a multi-turn agent session and the conversation history contains a tool call, any assistant message with tool calls passed back in subsequent user turns must preserve its full reasoning_content field — otherwise the API will return a 400 error.
Without it, the model's context is incomplete, which can lead to weaker instruction-following, more hallucinations, and a visibly degraded user experience. Missing reasoning = incomplete context = degraded reasoning quality.
Affected frameworks include TRAE, Cursor, Roo Code, Codex, GitHub Copilot CLI, Zed, AutoGen. We're actively working with the maintainers to push compatibility updates.
Affected models: MiMo-V2.5-Pro, MiMo-V2.5, MiMo-V2-Pro, MiMo-V2-Omni, MiMo-V2-Flash.
