<h3 id="important">IMPORTANT</h3>This model utilizes INT6 packing and cannot run natively on ComfyUI, clone the below custom node into your ComfyUI's custom_nodes directory to enable it<a target="_blank" rel="ugc" href="https://github.com/bakapotatolord/ComfyUI-PotatoForge-INT6">https://github.com/bakapotatolord/ComfyUI-PotatoForge-INT6</a>And yes, INT6, not a typo.It is an experiment to find a balance between INT4 and INT8 in terms of storage and quality. It's not a mixed model, quantized layers are INT6 Convrot. Generation speed is almost the same as INT8 Convrot.Tested on GTX 1660 Super so I cannot guarantee how it works on other GPUs.
