A ComfyUI custom node wrapper for the SUPIR image upscaler, an SDXL img2img pipeline with a custom ControlNet. It offers more efficient model loading, lower memory usage, wider hardware support, and more sampler options than the original implementation.

Use cases

• upscale low-resolution images with SUPIR in ComfyUI workflows
• restore and enhance old or blurry photos using diffusion-based upscaling
• build image restoration pipelines with SDXL img2img
• skip or replace SUPIR's first-stage denoising with custom preprocessing nodes
• run fast Lightning-model upscaling for quick experimentation

When to choose

• you already use ComfyUI and want SUPIR upscaling as nodes
• you need more sampler options and lower memory usage than the original SUPIR demo
• you want to combine SUPIR with LoRAs and other ComfyUI nodes

When to avoid

• you want actively developed SUPIR support - it's now in ComfyUI core and this wrapper only gets breaking bugfixes
• you don't use ComfyUI
• you have limited VRAM and high-resolution inputs, since memory needs scale with input resolution
