Google Research introduces Diffusion Controller for image generation
Google Research introduced Diffusion Controller, a lightweight steering network that attaches to text-to-image models, including closed-source ones, to improve prompt alignment without breaking baseline stability. It reframes denoising as a continuous control problem. The add-on network outperformed the industry standard for matching human preferences, according to the blog post.
