Source description

ImageUpscaleFlow is a dedicated workflow designed to upscale images using SeedVR2, currently the most powerful and freely available upscaler for ComfyUI. The example shown in the gallery demonstrates an impressive upscale of a 434 × 652 pixel image to a stunning 2484 × 3732 pixels. The remarkable quality of the result truly speaks for itself!

💡If you installed the SeedVR2 node before 2025-12-06, update it using the ComfyUI Manager. The latest version significantly reduces artifacts, especially when using the 7b_sharp model.
