w4a8 is a format using 4-bit weights and int8-convrot activations
Model source
Source description
w4a8 is a format using 4-bit weights and int8-convrot activations
Requires ComfyUI 0.31.0
int8_convrot VAE needs ComfyUI 0.36.0 for maximum speed benefit
It speeds up VAE decode times by ~2x
ref lora is the difference between fl2va and ref2va, completely experimental, I don't even know if it has a use case at this point.
w6a8 is a format using 6-bit weights and int8-convrot activation, work in progress
