Overview

About this model

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.

Common Questions

Frequently asked

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`.
