请求参数

只列出本模型接受的参数。请求中的其他字段在到达模型之前会被去掉。

消息内容

除了纯字符串，消息的 content 也可以是一个内容片段列表：

text

文本。

{
  "type": "text",
  "text": "Describe this."
}

image_url

一张图像，可以是公开的 https:// URL 或 data URL。

{
  "type": "image_url",
  "image_url": {

  "type": "file",
  "file": {
    "file_data": "data:application/pdf;base64,...",
    "filename": "report.pdf"
  }
}

响应

使用 stream: true 时，chat.completion.chunk 事件会携带 choices[].delta；流以 data: [DONE] 结束。
