it's not perfect, has a tendency to change colors a bit (better than USDU does though, with no tiling artifacts) and I'd welcome any suggested improvements. it does a pretty good job and handles all art styles I've attempted, including anime.

genning at these resolutions requires more VRAM even if it's SDXL. I have a 7900 XTX so I have no issues with this. IDK if it'll run on 16GB.

recommended SDXL models for this workflow, the best depends on what you're upscaling and how you tweak the settings:
