Summary
Nunchaku's SVDQuant method brings W4A4 diffusion inference to Diffusers, reducing VRAM from ~24GB to ~12GB on an RTX 5090 and generating 1024x1024 images in 1.7s. It supports NVFP4 for Blackwell GPUs and INT4 for older hardware, with the diffuse-compressor toolkit enabling custom quantization.
