Qwen-Image-2.1-Pro is the higher-quality model in the Qwen-Image 2.1 series. The same model generates images from a prompt and edits the images you send: pass up to 8 reference images in a request to replace a background, place a person or product in a new scene while keeping them recognisable, or combine elements from several images into one. Ask for a transparent background in the prompt and it can return a PNG with a transparent background.
