ssitu/ComfyUI_UltimateSDUpscale
ComfyUI nodes for the Ultimate Stable Diffusion Upscale script by Coyote-A.
Implements tiled image-to-image diffusion processing that breaks large images into smaller patches for upscaling, preserving fine details while reducing VRAM requirements and respecting the diffusion model's native resolution training bounds. Integrates directly into ComfyUI's node system as custom `image/upscaling` nodes with configurable tiling and blending parameters. Ports the established Ultimate Upscale algorithm from the Automatic1111 WebUI to ComfyUI's modular node architecture.
