What it is

Qwen Image 2.1 is an open-weight image model that is as comfortable editing as it is generating. In edit mode you attach one to ten reference images and address them in the prompt as <image1>, <image2> and so on, which makes product swaps, outfit changes, and style transfers a sentence rather than a mask.

It is slower and heavier than Z-Image Turbo, so CozyGPU schedules it on a 48 GB class GPU. Expect about 25 seconds a picture when the worker is warm.
