AI 接口列表聊天(Chat)
OpenAI格式(Completions)
https://token.firstpy.com/v1/chat/completions根据对话历史创建模型响应。支持流式和非流式响应。
兼容 OpenAI Chat Completions API。
鉴权
在 Header 添加参数 Authorization，其值为在 Bearer 之后拼接 Token
示例：Authorization: Bearer ********************
请求体
model*string
模型 ID
messages*array<object>
temperature?number
采样温度,默认1,取值范围 0～2
top_p?float
核采样参数,默认1,范围 0.0 到 1.0
n?integer
生成数量,默认1,取值范围 >= 1
stream?boolean
是否启用流式输出
stream_options?object
stop?string
停止序列
max_tokens?integer
最大生成 Token 数
max_completion_tokens?integer
最大补全 Token 数
presence_penalty?number
默认1,取值范围 -2.0～2.0,正值会根据token在历史文本中出现的频率进行惩罚，降低模型重复输出相同内容的概率
frequency_penalty?integer
默认1,取值范围 -2.0～2.0,正值会惩罚所有已经出现过的token，鼓励模型输出新的话题方向
logit_bias?object
user?string
tools?array<object>
tool_choice?string | object
response_format?object
seed?integer
固定随机种子，相同请求参数和seed值下模型输出尽可能保持一致，用于可复现的生成场景
reasoning_effort?string
推理强度 (用于支持推理的模型), low | medium | high
modalities?array<string>
audio?object
{
"model": "deepseek-v4.1-flash",
"messages": [
{
"role": "system",
"content": "string"
}
]
}返回响应
id?string
响应ID
object?string
固定值为chat.completion，标识返回对象类型
created?integer
响应生成的Unix时间戳
model?string
实际处理本次请求的模型ID
choices?array<object>
usage?object
system_fingerprint?string
