Comparison with Other Models

Vs GPT-4o: Qwen-Image outperforms GPT-4o in rendering and accurately placing multi-line text, especially in Chinese, while providing free or more affordable usage. In contrast, GPT-4o offers broader capabilities and integration with the ChatGPT ecosystem but is approximately twice as expensive

Vs Seedream 3.0: Both excel in handling Chinese and English text, yet Qwen-Image stands out with open-source accessibility and a better price point. Seedream 3.0 provides faster generation speeds and stable commercial support

Vs Midjourney: Qwen-Image achieves comparable quality in prompt fidelity and text rendering while remaining open and more affordable. Midjourney continues to be a commercial favorite for creative projects with fast generation speeds and rich visual variety but at a higher cost.

Limitations

Qwen-Image offers excellent price-performance balance but may lag behind some proprietary solutions in ultra-high-definition and niche domain-specific enhancements. Processing speed and output quality may vary depending on megapixel load and task complexity.

How to use Qwen Image API

Install any OpenAI-compatible SDK, point it at api.aimlapi.com/v1, and set the model to alibaba/qwen-image.
import requests

r = requests.post(
    "https://api.aimlapi.com/v1/images/generations",
    headers={"Authorization": "Bearer " + AIMLAPI_KEY},
    json={
      "model": "qwen-image",
      "prompt": "A cat holding a sign that says hello"
    },
)
print(r.json())
const r = await fetch("https://api.aimlapi.com/v1/images/generations", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.AIMLAPI_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    "model": "qwen-image",
    "prompt": "A cat holding a sign that says hello"
  }),
});
console.log(await r.json());
curl -X POST https://api.aimlapi.com/v1/images/generations \
  -H "Authorization: Bearer $AIMLAPI_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"qwen-image","prompt":"A cat holding a sign that says hello"}'

OpenAI-compatible — swap the base URL and it works with your existing SDK.
