Chat Completions（非流式）

适用于后台任务、结构化输出、短问答和不需要实时展示生成过程的场景。省略 stream 或传入 false 时，接口一次性返回完整 chat.completion 对象。

请求体

string

required

模型名称。可通过模型列表查询。

array<object>

required

对话消息数组。每条消息至少包含 role 与 content。常见角色为 system、developer、user、assistant、tool。第三方兼容接入建议优先用 system 放全局指令；如果明确按 OpenAI 新模型语义接入，可用 developer 表示应用开发者指令。

string | array

消息内容。字符串表示纯文本；数组可传多模态内容，例如 { "type": "text" } 与 { "type": "image_url" }。图片 URL、base64 和本地图片上传处理见图像输入与图床上传。

boolean

省略或传 false 时为非流式响应。

object

指定输出格式。常用于 JSON 输出或 JSON Schema 结构化输出。结构化输出对模型能力有要求，建议先用小 schema 验证。

array<object>

函数调用工具列表。

string | object

控制工具调用策略。

number

采样温度。默认值由上游模型决定。

number

核采样参数。

integer

最大生成 token 数。部分新推理模型也支持或更推荐 max_completion_tokens。

integer

最大补全 token 数，通常包含推理 token。对 GPT-5 系列等推理模型更明确。

number

随机种子。上游支持时可提升复现性。

string

推理强度。常见值包括 none、minimal、low、medium、high、xhigh；是否生效取决于模型。延迟敏感场景可先评估 low，质量优先场景再逐级提高。

  "type": "image_url",
  "image_url": {
    "url": "data:image/png;base64,BASE64_IMAGE_DATA"
  }
}
