Aperçu

À propos de ce modèle

Qwen 2.1 Image to Image edits, restyles, and recombines up to 10 reference images from a single text prompt, preserving identity and composition where you want it kept. An optional inpainting mask switches the request into local-edit mode, changing only the white-marked region of one reference image while leaving the rest untouched. For pure text-to-image generation, see Qwen 2.1 Text to Image; for Alibaba's newer generation, see Qwen 3.0 Image to Image.

1Product Restyling: Swap colorways, materials, or backgrounds on an existing product photo while keeping its shape and layout.

2Multi-Image Composition: Combine elements from up to 10 reference images into a single coherent scene.

3Local Inpainting: Use a mask to regenerate only a specific object or area (e.g. a poster on a wall) while preserving everything else pixel-for-pixel.

4Character & Style Consistency: Carry a subject's appearance across new scenes and outfits from a single reference set.

5Batch Creative Variations: Generate several edited takes of the same base image by varying only the prompt and seed.

How to Use Qwen 2.1 Image to Image API

Provide reference images: pass 1 to 10 URLs as images_list; order matters when your prompt says "the first image", "the second image", etc.
Describe the edit: write a prompt describing the transformation you want.
Optional — local edit: supply mask_url (white = change, black = keep) together with exactly one reference image to edit only that masked region.
Submit the task:

curl -X POST "https://api.muapi.ai/api/v1/qwen2-1-image-to-image" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "images_list": ["https://example.com/a.jpg", "https://example.com/b.jpg"],
    "prompt": "Replace the backpack in the first image with the colour scheme from the second image, and leave everything else unchanged",
    "resolution": "1K"
  }'

Poll for the result: use the returned request_id against the standard predictions result endpoint until status is completed.

Questions courantes

Foire aux questions

What is Qwen 2.1 Image to Image?

Qwen 2.1 Image to Image is Alibaba's reference-image editing model — it edits, restyles, and recombines existing images from a text prompt instead of generating from scratch.

How many reference images can I use?

Between 1 and 10 images per request. More references reduce how much detail each individual one keeps, so stay within 4 when fidelity matters.

How does the inpainting mask work?

Supply `mask_url` — a black-and-white image where white marks the area to change — together with exactly one reference image. Only that white-marked region is regenerated; everything else is kept unchanged. Local-edit mode ignores `aspect_ratio` and `enhance_prompt`.

What aspect ratio does the output use?

By default (`auto`) it matches the first reference image's aspect ratio, snapped to the nearest supported ratio. You can override it explicitly outside of local-edit mode.

Can I generate transparent-background output?

Yes — set `background` to `transparent` with `png` or `webp` as the output format; it cannot be combined with a mask or with `jpeg`.
