If you are anything like me, you have hundreds, if not thousands of SD 1.5 and SDXL images saved. Some of them are probably really cool but the quality or details could be improved.

This is an image to image workflow using Flux checkpoint to enhance your images.

It includes an optional upscaler. I also noticed that sometimes the eyes get really bad using Flux to enhance SD 1.5 images, so there's also an optional eye detailer in the workflow.
