Published description

本卡聚焦非流式 POST /inference/v1/chat/completions，输入模型名与会话消息，输出 chat completion 及可选 usage。文档还描述工具调用、流式和采样参数；这些选项受模型与配置约束，不表示工具已执行或所有模型均支持。

Inputs

model：必需字符串，指定模型。
messages：会话消息列表；附件说明提供 prompt_token_ids 时会忽略 messages，此时模板和 tokenization 由调用者负责。
可选 stream、tools、tool_choice、response_format 及采样参数；具体约束与支持模型须分别核对。

Outputs

200 application/json 响应包含 id、created、model、choices，object 默认为 chat.completion，可选 usage 等字段。
tools 描述允许模型生成函数调用输入，不代表服务已经执行外部函数。
