ComfyUI Tutorial Series: Ep21 - How to Use OmniGen in ComfyUI

Sobre esta lección

Welcome to Episode 21 of our ComfyUI tutorial series! In this video, we’ll cover OmniGen, a new image-generation model that enables a range of creative possibilities using multi-modal prompts within ComfyUI. We’ll guide you through setting up OmniGen, installing necessary dependencies, and handling common installation issues. This model can generate complex images, combine multiple prompts, and apply different artistic styles—all in one workflow. Note that OmniGen requires a high amount of VRAM (around 16GB), so make sure your system is equipped.
