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 Header 参数
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)
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
