Python SDK

安装 OpenAI SDK：

pip install openai
from openai import OpenAI

client = OpenAI(
    base_url="https://laogouapi.com/v1",
    api_key="sk-your-api-key",
)

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "你好"}],
    max_tokens=100,
)

print(response.choices[0].message.content)

Node.js SDK

npm install openai
import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://laogouapi.com/v1",
  apiKey: "sk-your-api-key",
});

const response = await client.chat.completions.create({
  model: "gpt-4o",
  messages: [{ role: "user", content: "你好" }],
  max_tokens: 100,
});

console.log(response.choices[0].message.content);

流式输出

所有 Chat 接口均支持 SSE 流式输出，设置 "stream": true 即可：

stream = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "写一首诗"}],
    stream=True,
)

for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")

所有接口详细参数请参考左侧「接口文档」分组。
