Nunchaku Lite brings big image models to more GPUs
- Nunchaku Lite now works natively in Diffusers for SVDQuant 4-bit (W4A4) diffusion inference.
- The team says it cuts peak VRAM by up to 50% and makes generation about 30% faster without hurting image quality.
- The screenshot shows an example dropping from 31.1 GB to 16.0 GB peak memory, with end-to-end latency improving from 3.00s to 1.68s.
- The practical effect: larger image models become usable on many more GPUs.
