2.请求说明

  • 请求方法: POST
  • 请求地址
  https://gateway.theturbo.ai/v1/chat/completions

3.请求参数

3.1 Head参数

参数名称 类型 必填 说明 示例值
Content-Type string 是 设置请求头类型，必须为application/json application/json
Accept string 是 设置响应类型，建议统一为application/json application/json
Authorization string 是 身份验证所需的 API_KEY，格式Bearer $YOUR_API_KEY Bearer $YOUR_API_KEY

3.2 Body 参数 (application/json)

参数名称 类型 必填 说明 示例
model string 是 要使用的模型 ID。详见概述列出的可用版本，如 gemini-1.5-pro。 gemini-1.5-pro
messages array 是 聊天消息列表。数组中的每个对象包含role (角色) 与 content (内容)。 [{"role": "user","content": "你好"}]
role string 否 消息角色，可选值: system、user、assistant。 user
content string 否 消息的具体内容。 你好，请给我讲个笑话。
temperature number 否 采样温度，取值0~2。数值越大，输出越随机；数值越小，输出越集中和确定。 0.7
top_p number 否 另一种调节采样分布的方式，取值 0~1。和 temperature 通常二选一设置。 0.9
n number 否 为每条输入消息生成多少条回复。 1
stream boolean 否 是否开启流式输出。设置为 true 时，返回类似 ChatGPT 的流式数据。 false
stop string 否 最多可指定 4 个字符串，一旦生成的内容出现这几个字符串之一，就停止生成更多 tokens。 \n
max_tokens number 否 单次回复可生成的最大 token 数量，受模型上下文长度限制。 1024
presence_penalty number 否 -2.0 ~ 2.0，正值会鼓励模型输出更多新话题，负值会降低输出新话题的概率。 0
frequency_penalty number 否 -2.0 ~ 2.0，正值会降低模型重复字句的频率，负值会提高重复字句出现的概率。 0
reasoning_effort string 否 用来控制模型在推理任务中投入多少“计算精力”。目前只有gemini-2.5-flash-preview-04-17支持。支持low medium high none。默认为low。 low
