flux1-schnell-bnb-nf4 support?

[Yogesh-DevHub]

the wiki says it supports black-forest-labs/FLUX.1-schnell can it be for flux1-schnell-bnb-nf4?

Not yet. That is just the more experimental part using diffusers. But these two models should work (just place the safetensors files in models/checkpopints):

I'm trying to figure out how ComfyUI handle gguf-files and hopefully will add this soon™.

I tried both the models, but it is generating blur images. It is like, it just stops after first or second step leaving the blur/noisy image as it is, can you have a look here.

Thank you.

It might be that you need to make a new Performance setting. Flux can be a bit picky with CFG and Sampler for example.

This is what I use for Flux.1 Dev:

...and this for Flux.1 Schnell

(These are probably not "the best" settings, but they should be a good start.)

It works, thank you. I will be using for few days now.

I am trying to get Fooocus like applications which supports flux, I made a video on "metercai/SimpleSDXL", but it freezes sometimes so I was searching for other forks and found this.

RF has some interesting features (PowerUp), over what Fooocus offers.
I don't think PowerUp works with flux, am I correct?
Will RF be able to use LORA for flux? Are there any plans?

[yownas]

Sorry, no, most of the PowerUps will only work with SDXL models. But it might be something we take a look at later to see if we can find good controlnets for Flux.

Loras for Flux should work. I haven't tried them a lot, but you can find some on civitai.com (make sure to filter for Loras for the correct Flux-version.)
