The module already has VAE. Unless you have specific coloring requirements, it is recommended to use the VAE inside the module. Due to the unique nature of v-pred, I have created a dedicated section for v-pred.

Recommended Parameters:

• Samplers: DDPM(suggest) > Euler > DDIM (⚠️ Other samplers will not work properly)

  • DDPM

    • CFG: 5.5 ( around 5.5)

    • Steps: 40 ( or higher)

    • Hi-res fix: Upscale 1.5x or higher, Denoising strength 0.15–0.45

  • Euler

    • CFG: 4~7

    • Steps: 20~35

    • Hi-res fix: Upscale 1.5x or higher, Denoising strength 0.15–0.45

Forge Configuration Guide (Update to the latest version):
Select SDXL from FreeU dropdown menu, set the start to 0.6 and end to 0.8.
