Omnigen 2 is out

by AI Generated Robotic ContentImagePosted on Comments are Disabled

It’s actually been out for a few days but since I haven’t found any discussion of it I figured I’d post it. The results I’m getting from the demo are much better than what I got from the original. There are comfy nodes and a hf space: https://github.com/Yuan-ManX/ComfyUI-OmniGen2 https://huggingface.co/spaces/OmniGen2/OmniGen2 submitted by /u/Betadoggo_ [link] [comments]
