Stable Cascade can generate photos and give variations of the exact image it created, or try to increase an existing picture’s resolution. Other text-to-image editing features include inpainting and outpainting, where the model will fill edit only a specific part of the image, as well as canny edge, where users can make a new photo just by using the edges of an existing picture.
