## What you will build

Generate a square product illustration through Model Studio's OpenAI-compatible endpoint and download it.

## 1. Before you start

Set `DASHSCOPE_API_KEY` and `QWEN_WORKSPACE_ID`.

## 2. Try the task

Save as `qwen_image.py`.

## 3. Check the result

Check that the result is square and opens as an image, then rename it with the extension matching the content type.

## 4. Troubleshooting

- A valid key from another region may fail against this workspace host.
- Keep the `x` separator in the compatible endpoint's size value; do not mix request conventions from the DashScope protocol.
- Text-only generation omits `image`; an empty image array is not a substitute.
- If the response contains a URL, download it rather than trying to base64-decode it.

## 5. Try it on your task

Try an English brief and an equivalent Chinese brief for the same composition, if both languages matter to your product.

Keep a small evaluation sheet alongside the image: the exact prompt, model or endpoint, requested dimensions, actual dimensions, elapsed time and whether the file met your brief.

For a second attempt, change one instruction and keep the rest of the brief fixed.
