Zib distilled 4-8 steps, working good with 4 steps, but 8 steps is better.
Merged with one of my lora and 3 blocks of the turbo version.
Use euler/simple with cfg 1.

Your work is good, but the integration of Lora washes out the tones and alters the ranges of black tones as well as the contrasts.š
I'll try to do better next time.
@jiceĀ šš
Ultimate is an incredibly good checkpoint. With AuraFlow 10, it renders virtually any image almost flawlessly. And it's incredibly good with text. Impressively good in my opinion. It has very strong contrast and produces an incredible amount of detail. However, for me, both of these qualities are a little too much, resulting in a loss of realism, for example, in skin tones. It's very fast; 6 Euler/Simple steps are sufficient in my opinion. Thank you for it.
Yes, the contrast is a bit too much, it's a flaw and sometimes a strength. Thank you for your feedback.
@jiceĀ This is certainly interesting for some builds, no question. That's undoubtedly also due to the fact that it's the base version and not the turbo version. I like your checkpoint and I'm really looking forward to future versions :)
@GoreanĀ I don't have much time at the moment, I think the next version will be a conversion to nvfp4, it speeds up rendering on the 5000 series and it should "break" this excess of contrast a bit.
Can you add smaller model FP8 or Q8 GUFF ??
Looks great!
An nvfp4 (5gb) version is coming soon.
@jiceĀ hey,does nvfp4 work in older nvidia cards?
@alex9692Ā Yes, but without acceleration.
@jiceis quality better than fp8?Ā
@alex9692Ā for me yes
On gf1050m + ComfyUI they work, but for some reason not all of them
