About Topaz Bloom
Topaz Bloom is a generative image upscaler that invents new, believable detail as it enlarges, similar to Magnific. Steer the added detail with a prompt and adjust how much is invented.
Use it to creatively enhance and upscale images with adjustable creativity, texture, and optional prompt guidance.
