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.

where is files?
should be available? i pulled it down for 2 min to fix a minor detail
I have an error after global upscaling. I guess because I'm not sure where to put downloaded extra files from your provided notes.
Well it was \ComfyUI\models\ultralytics
It should say the location in the download notes :)
@DonutsDelivery Also, if you are open to suggestions, the only thing missing from my point of view is the ability to bypass options with one click switcher as I've seen in other workflows. Just some switches to turn on/off upscaler, eyes detailer, face detailer. Then I could use this workflow also for fast prompt tests.
@Monsieur_Orange that sounds really cool, could you link me to it? i havent used other peoples workflows for a long time so dont know the best way to make that.
@DonutsDelivery https://openart.ai/workflows/ailab/flux-txt2imag-img2img-upscale-workflow/2PuxRMuyzvuwt087020I The node is "Fast Groups Bypasser".
@Monsieur_Orange incredible man, thanks!
V4 is great thanx! I forgot to tell you before, but I think your "Save image" is too simple. I suggest you to have a look on that (hidden) node : WAS Suite > IO > Image Save
