FLUX 1 NF4 basic workflow + img2img for lowend GPU for ComfyUI

The new FLUX model is yet far from practical reach for lower end GPU. Even though, the community made some insane improvements to get it running in a near proper way. ~20s per image. It is still very impressive, to see the capability of the model to follow the prompt given. Still, it is to mention, that the FLUX model is not very versatile – as the output is very stereotypical, sexist and boring out of the box. With the raise of retrained models and LoRas, we will sure see some new dimensions.

pose variations

Variations for the body pose only in the prompt seem to work pretty good, when stereotypical.

img2img workflow

The img2img workflow is one of the most powerful features of working with generative image tools. A pretty basic workflow without masking for the lowend NF4 models looks like this:

With variation of the denoise value, we can set a distance how far we can vary from the original. Denoise needs to be pretty high to see variations in this workflow 🙁
