v1.0 - changes anatomy and overall picture quality
v1.5 - only changes anatomy
4B - only changes anatomy

This concept slider LoRA was trained to correct the anatomy / quality issues with Klein models.

The LoRA can't fix everything but it helps. It was basically trained so that negative weights have the effect of a negative stable-diffusion prompt, and positive have the opposite effects.

Weight 2.0 mostly keeps the seed intact and can be used to fix minor glitches, 3.0 fixes some more prominent artifacts.

The LoRA also improves a bit the overall quality of the picture, makes the picture more "clean".

Note on the 4B version:
I never managed to generate good quality images without the LoRA, so I didn't post images for it. I was able to confirm that the LoRA behaves similarily to the 9B version, but I probably won't update it unless the bad quality of the 4B model is due to my workflow.

Hope you like it!
