ssitu/ComfyUI_UltimateSDUpscale
ComfyUI nodes for the Ultimate Stable Diffusion Upscale script by Coyote-A.
This tool helps digital artists and graphic designers enhance the detail of their AI-generated images, especially when working with Stable Diffusion. It takes a lower-resolution AI-generated image and upscales it significantly while preserving or improving fine details. The output is a high-resolution image with enhanced clarity, ideal for printing or high-quality digital display.
1,470 stars. Actively maintained with 3 commits in the last 30 days.
Use this if you need to upscale large AI-generated images without losing intricate details or encountering hardware memory limitations.
Not ideal if you are looking for general image upscaling that isn't specifically designed for tiled Stable Diffusion processing.
