5. How to Use Qwen AI – Practical Examples

Getting started with Qwen AI takes less than five minutes. Below are three practical walkthroughs covering text generation, image creation, and agent building.

5.1 First Text Generation via API (Python)

Step 1: Install the OpenAI-compatible Python SDK (Qwen uses the same interface):

pip install openai

Step 2: Obtain your API key from Alibaba Cloud Model Studio → API Keys → Create New Key.

Step 3: Run your first completion:

import openai

client = openai.OpenAI(
    api_key=”YOUR_QWEN_API_KEY”,
    base_url=”https://dashscope.aliyuncs.com/compatible-mode/v1″
)

response = client.chat.completions.create(
    model=”qwen-plus”,
    messages=[
        {“role”: “system”, “content”: “You are a helpful assistant.”},
        {“role”: “user”,   “content”: “Explain quantum entanglement in simple terms.”}
    ],
    max_tokens=512
)

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

📌 Qwen’s API is OpenAI-compatible, so any existing OpenAI SDK integration requires only a base_url change to migrate.

5.2 Generate an Image with Qwen-Image-Max

Qwen-Image-Max excels at generating photorealistic images with accurate text rendering. Here is a minimal Python example:

import dashscope
from dashscope import ImageSynthesis

dashscope.api_key = “YOUR_QWEN_API_KEY”

response = ImageSynthesis.call(
    model=”wanx-v1″,
    prompt=”A futuristic city skyline at sunset, neon signs in English and Chinese, “
           “photorealistic, 4K”,
    n=1,
    size=”1024*1024″
)

print(response.output.results[0].url)

Key tips for best results with Qwen image models: use bilingual prompts (English + Chinese) for text-heavy designs; specify lighting, style, and resolution explicitly; and use Qwen-Image-Edit for iterative refinement of generated outputs.

5.3 Build a Simple Agent with Qwen-Agent

Qwen-Agent is an open-source framework that lets you build autonomous AI agents with tool use, RAG, and code execution. Install it from GitHub:

pip install qwen-agent

A minimal web-browsing agent:

from qwen_agent.agents import Assistant

# Define tools available to the agent
tools = [“web_search”, “code_interpreter”]

agent = Assistant(
    llm={“model”: “qwen-plus”},
    system_message=”You are a research assistant. Search the web and summarise findings.”,
    function_list=tools
)

messages = [{“role”: “user”, “content”: “What are the latest AI safety papers from 2025?”}]
for response in agent.run(messages=messages):
    print(response[-1][“content”])

Qwen-Agent also integrates with MCP (Model Context Protocol) servers, enabling seamless connection to databases, APIs, and external services without custom tool wrappers.

6. Run Qwen Locally – Self-Hosting Guide

One of Qwen’s greatest advantages is that open-weight models can be deployed on your own hardware, giving you full data privacy and offline capability.

6.1 Using Ollama (Easiest Method)

Ollama is the simplest way to run Qwen models locally on Mac, Windows, or Linux:

# Install Ollama from https://ollama.com
ollama pull qwen2.5:7b
ollama run qwen2.5:7b

Ollama supports Qwen2.5 in 0.5B, 1.5B, 3B, 7B, 14B, 32B, and 72B parameter sizes.

6.2 Using Hugging Face Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = “Qwen/Qwen2.5-7B-Instruct”
tokenizer  = AutoTokenizer.from_pretrained(model_name)
model      = AutoModelForCausalLM.from_pretrained(model_name, device_map=”auto”)

prompt = “Write a Python function to sort a list of dictionaries by a key.”
inputs = tokenizer(prompt, return_tensors=”pt”).to(model.device)
output = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(output[0], skip_special_tokens=True))

6.3 Using vLLM for Production Serving

For high-throughput production deployments, vLLM offers PagedAttention and continuous batching:

pip install vllm

# Serve Qwen3.6-27B on GPU
python -m vllm.entrypoints.openai.api_server \
    –model Qwen/Qwen2.5-72B-Instruct \
    –served-model-name qwen \
    –tensor-parallel-size 4

📌 vLLM’s OpenAI-compatible server lets you point any existing ChatGPT client at your self-hosted Qwen instance.
