These VAEs are modified versions of
madebyollin's
sdxl-vae-fp16-fix.
These VAEs should not produce a NaN in VAE error even when used on half precision.
They have been modified using the ideas from
VAE-BlessUp script to produce higher contrast and lower brightness images than the original version.
For most SDXL models, you probably should probably just use the non-blessed
sdxl-vae-fp16-fix.
I made these mostly for fun, but found that slightly increasing contrast and decreasing brightness actually improved the outputs on the model I was testing.
You may find one of them to be beneficial for PonyDiffusionV6-XL and other models based on it.
Best -
sdxl-vae-fp16fix-blessed.safetensors = 1.1 contrast multiplier/0.7 brightness multiplier
Good -
sdxl_vae-fp16fix-c-1.1-b-0.5.safetensors = 1.1 contrast multiplier/0.5 brightness multiplier
High Contrast -
sdxl_vae-fp16fix-c-1.2-b-0.7.safetensors = 1.2 contrast multiplier/0.7 brightness multiplier
Very High Contrast -
sdxl_vae-fp16fix-c-1.2-b-0.5.safetensors = 1.2 contrast multiplier/0.5 brightness multiplier
sdxl_vae-fp16fix-c-0.9-b-0.9.safetensors = 0.9 contrast multiplier/0.9 brightness multiplier
sdxl_vae-fp16fix-c-0.8-b-0.9.safetensors = 0.8 contrast multiplier/0.9 brightness multiplier
sdxl_vae-fp16fix-c-0.8-b-0.8.safetensors = 0.8 contrast multiplier/0.8 brightness multiplier
