OmniGen2 Multimodal Image Editing ComfyUI Workflow - Windows One Click Installer

OmniGen2 is now available and can run on low VRAM devices! I’ve created a one-click Windows installer for ComfyUI, plus a workflow using the Detail Daemon node for extra detail.
 
What is OmniGen2?
OmniGen2 is a new open-source AI model that can both understand images and generate high-quality images from text prompts. It supports text-to-image, image editing by instructions, and can combine elements from multiple images. It’s fast, efficient, and works great even on consumer GPUs.
