In this in-depth video, we explore the new OmniGen 2 image editing model and how it compares to other popular AI tools like Flux Context. The video covers a hands-on test of OmniGen 2 using ComfyUI , including text-to-image generation, instruct-guided image editing, and workflows for advanced users. Discover the model’s architecture improvements, such as its dual-path transformer design , and learn how to set it up locally with step-by-step guidance. The creator also shares real-world testing results, performance benchmarks, and direct comparisons between OmniGen 2 and Flux Context in tasks like object replacement, color transformation, and style consistency. Whether you're an AI enthusiast, digital artist, or developer looking to experiment with cutting-edge models, this video provides valuable insights into what OmniGen 2 can (and cannot) do.

Omnigen2 ComfyUI DOCS
https://docs.comfy.org/tutorials/image/omnigen/omnigen2
Steps (via ComfyUI Org):
1 - Load Main Model: Ensure the Load Diffusion Model node loads omnigen2_fp16.safetensors
2 - Load Text Encoder: Ensure the Load CLIP node loads qwen_2.5_vl_fp16.safetensors
3 - Load VAE: Ensure the Load VAE node loads ae.safetensors
4 - Set Image Dimensions: Set the generated image dimensions in the EmptySD3LatentImage node (recommended 1024x1024)
Input Prompts:
5 - Input positive prompts in the first CLipTextEncode node (content you want to appear in the image)
6 - Input negative prompts in the second CLipTextEncode node (content you don’t want to appear in the image)
7 - Start Generation: Click the Queue Prompt button, or use the shortcut Ctrl(cmd) + Enter to execute text-to-image generation
8 - View Results: After generation is complete, the corresponding images will be automatically saved to the ComfyUI/output/ directory, and you can also preview them in the SaveImage node
image edit workflow attached below, in case you don't know how to get the file from Comfyui Docs.
