hey @Dragonjinx we have conversion scripts for stable diffusion here diffusers/convert_original_stable_diffusion_to_diffusers.py at main 路 huggingface/diffusers 路 GitHub
Note that we can鈥檛 support arbitrary conversions for arbitrary models and I don鈥檛 think we have any recommended vae conversion scripts. You might have to write the code yourself
