4.0 bug: If you have more than one male or female face, use 3.0.

This is optimized for speed. The steps are lower because it is not nessesary to have them as high as people usually do for lower denoise upscaling.

This is a first attempt at native upscaling with FLUX NF4 that just released (native in a sense that it uses Flux instead of SDXL, SD1.5 etc.). it is a 2 iterative upscale workflow. If you get memory allocation errors, bypass the second up-scaling column so it skips the 3rd pass. I use 12gb vram for this workflow.

If you prefer using Dev i would suggest still using NF4 upscaling for a speed increase.
