OminiControl is a minimal yet powerful universal control framework designed for diffusion transformer models like FLUX. It supports subject-driven control and spatial tasks (such as edge guidance and image restoration). The design of OminiControl is extremely streamlined, introducing only 0.1% additional parameters to the base model while retaining the original model structure. This project is developed by the Learning and Vision Laboratory at the National University of Singapore, representing the latest advancements in image generation and control technologies in the field of artificial intelligence.
