Published description

官方 Chat 页面记录 POST https://api.mistral.ai/v1/chat/completions。请求体为 application/json，必填 model 与 messages；messages 由角色和内容组成。可选 max_tokens、temperature、tools、tool_choice、response_format、stream 等参数。默认返回完整 JSON，stream=true 时以 data-only server-side events 返回增量结果，并以 data: [DONE] 结束。官方 SDK 和 cURL 示例使用 MISTRAL_API_KEY；这里只整理文档声明，不代表当前已配置密钥、获准调用任何模型或完成生成请求。

Inputs

  • 必填 model：模型 ID；可访问模型范围需由调用方确认。
  • 必填 messages：包含 system、user、assistant 或 tool 消息的角色/内容列表。
  • 可选 max_tokens、temperature、top_p、tools、tool_choice、response_format、stream 等。

Outputs

  • HTTP 200 application/json：choices、created、id、model、object、usage 等字段。
  • stream=true：text/event-stream，返回数据事件并以 data: [DONE] 终止。

Unknown is not a claim that a service is free, anonymous, private or unavailable.

Limitations

  • 提示 token 数加 max_tokens 不得超过模型上下文长度。
  • JSON mode 仍要求提示明确要求模型输出 JSON；schema 模式按文档指定 JSON schema。
  • 模型可用性、默认采样参数可能因 model 不同；本次未调用 models 或补全端点验证。

Unknowns

  • 账户开通、密钥权限和指定模型的实际可用性未知。
  • 绝对价格、免费额度、速率限制和配额未知。
  • 数据保留、训练使用及驻留政策未由本次正文覆盖。
  • 未执行 API 请求，未验证回复质量、延迟、错误处理或工具调用行为。

Fixed profiles, conditions and evidence

Read state: not_checked; review state: unknown. Do not combine different profiles.

资料与来源声明不等于本站实测；未列出的条件仍未知。

结构化配方只按公开声明检查约束与接口，不执行任务或授予权限；缺失记录保持未知，接口兼容不证明实际成功。

Add a public correction or observation

Submit only facts you may disclose, without private tasks, customer data or credentials. Corrections are proposals; observations are conditional contributor reports, not automatically verified facts, commercial calls or income.

Propose a sourced summary correction

This form proposes a summary change for the current fixed version. Other supported fields use the original API. Concurrent version changes return a conflict.
