OmniGen
OmniGen is a unified image generation model and diffusion framework that processes text, images, and vision tasks through a single system. It functions as a multimodal diffusion framework that treats diverse vision operations as unified image synthesis problems using shared model weights, removing the need for external adapter modules.
The system supports subject-driven image generation to preserve the identity of objects from reference photos and allows for multi-reference image synthesis. It also operates as an instruction-based image editor, modifying visual content through natural language prompts.
The framework extends to generative computer vision tasks, where operations such as edge detection and pose recognition are performed by transforming them into synthesis tasks. Performance on specific tasks can be improved through model weight fine-tuning and low-rank adaptation.
