OpenAI SDK 快速接入：Python / Node.js 示例

OpenAI SDK 是目前兼容性最广的大模型接入方式，绝大多数中转站和国内模型都支持 OpenAI 兼容接口。

Python 示例

pip install openai

from openai import OpenAI

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

resp = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "用一句话介绍自己"}]
)
print(resp.choices[0].message.content)

Node.js 示例

npm install openai

import OpenAI from "openai";

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

const resp = await client.chat.completions.create({
  model: "gpt-4o",
  messages: [{ role: "user", content: "用一句话介绍自己" }],
});
console.log(resp.choices[0].message.content);

切换模型

只需修改 model 字段，如 claude-3-5-sonnet、gemini-1.5-pro，其他代码不变。
