Qwen API Guide: Python & Node.js Integration Outside China

What Is the Qwen API?

The Qwen API is Alibaba Cloud's developer interface for their Qwen (通义千问) large language model series. The API follows the OpenAI chat completions format, making it a drop-in replacement for developers already using GPT models.

   Change base_url in your SDK

   One line of code — see examples below.

Python Integration: Qwen API

Install the OpenAI Python SDK: pip install openai

from openai import OpenAI

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

response = client.chat.completions.create(
    model="qwen-3",  # or qwen-max, qwen-plus, qwen-2.5
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Explain transformer architecture in 3 sentences."}
    ],
    max_tokens=1024
)

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

For streaming responses:

stream = client.chat.completions.create(
    model="qwen-max",
    messages=[{"role": "user", "content": "Write a Python function for binary search."}],
    stream=True
)

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

Node.js Integration: Qwen API

Install: npm install openai

import OpenAI from "openai";

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

const response = await client.chat.completions.create({
    model: "qwen-3",  // or "qwen-max", "qwen-plus"
    messages: [
        { role: "user", content: "Translate this to Chinese: Hello, world!" }
    ]
});

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