So I recently switched to ForgeUI and they have plenty of features integrated out of the box.

In the context of FreeU, what exactly B and S are modifying? I spent a whole day trying to wrap my head around their exact functionality. Some say keep B>1 and S<1. Some say it adds sharpness and saturation, and the preset on their github didn't work for me, well atleast with the prompt I was tweaking.

But while I was fiddling around with FreeU, I observed lot of drastic modification in the generated image, which gave me hope that it just might be tool to realign the image in accordance to my prompt.

The paper mentions it manipulates main net features(B) and skip features(S).

Not sure what the main net features are, but I'm assuming skip features are like clip skip?

Although the paper mentions S didn't do anything, in my tests (sdxl base), it had a tremendous amount of adverse effect on the image generated.

TBH, i enjoy using DPO more than freeU, but I'm curious to learn.

Is there a DPO extension?

[–] idkman@lemmy.dbzer0.com 1 points 8 months ago

Haha no. I mean in the context of providing in control, DPO does a better job than FreeU.
