1. 概述

业界第一大语言模型。

2. 请求说明

• 请求方法:POST

• 请求地址:

  https://gateway.serevixai.ai/v1/chat/completions

3. 请求参数

3.1 Header 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。详见模型列表列出的可用版本，如 gpt-4o。	gpt-4o
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
