Moebius is an open image inpainting model. Inpainting means you keep most of an image, mask the area you want changed, and ask the model to generate only the missing or unwanted region.
That makes it different from a generic prompt-only image generator. If you have a room photo with an object to remove, a portrait with a damaged background, or a scene where one area needs repair, Moebius gives you a focused edit instead of forcing you to regenerate the whole image. The public Space includes variants for natural scenes and faces, so the first test can match the kind of image you care about.
