[Marcel]

Thanks for the tutorial. Really well explained and great editing.

[spoonman]

The way you explained this Flux model is clear and crisp 👍🏼👍🏼
Excellent, no really excellent step by step instructions 👍🏼👍🏼
I cannot explain how much this video means to me. Fantastic!!
Oh, and you have a very pleasant voice.
Thanks again!

Unfortunately Flux Pro version is not available any longer. By the way, I think Stable Difusion is obsolete. Flux (and Mystic) is erasing it. Thank you for this lesson, again.

[ChristophBehl-kx]

Great course! I have one contribution. In this chapter, you could explain that by downloading the image and loading it into ComfyUI, it grabs the metadata along with the entire workflow. I was initially confused about why we needed to download the image, but then I figured it out.

i tried f8, using a 4070 12gb card, with 32gb, and this is the second time it crashed. Not as violently as the 16bit version. I'm still not sure what i'm doing wrong. It also took forever trying to load. I bought more ram, i'm hoping that will help out here. I can only assume i'm still maxing out the ram. Maybe a bigger swap?

[LX]

Since flux launched, I kept running away from it, due to how complicated it looked. You explained quite everything needed to get started. Thank you for this video!

[daykeyy]

Great tutorial series, very easy to understand. Thank you :)

[eslamafifi]

amazing tutorial
thank you very much

[GenoG]

I have to say that I really appreciate your help learning all of this. Your videos are very well made, detailed and informative. I have NEVER wanted to use ComfyUI and now I LOVE IT! I watched several videos and they always made my head hurt!! Yours made sense!! Great job! I'm looking forward to watching more of them... I know I am barely scratching the surface! 🤓

Milion tutorials how to use FLUX it in Comfy UI and very few how to set everything to work in normal UI for ordinary people and none how to use Controlnet with it without Comfy UI involved.

[tombkn]

thanks very much, i have a problem : when i generete a picture it stucks : l after loarded completely in ksampler 0%__I 0/4 [00:00<?, ?it/s] do you know what i can do? im desperade

[Pikselation_T.I.W.]

Is it possible to have a separate directory for my flux models on a different drive? I really don't want to move my entire automatic 1111 folder to a different drive

[christophermalone]

Hahaha, "I am not a witch".

[itsmewaldi]

How would you simplify their workflow?

I also find it needlessly complex.

[moc_santos]

I'm crashing here, is it because I have 16gb of ram? I'm using a rtx 3060 12gb.

[hodeehum]

Thanks for your great contribution.Your videos and other materials provide a comprehensive and easy-to-follow resource for using ComfyUI and Flux together.
