SafeDiffusion-R1 enhances image model safety with online reward steering

Researchers have developed SafeDiffusion-R1, a new framework for enhancing the safety of diffusion models. This method utilizes an online reinforcement learning approach with Group Relative Policy Optimization (GRPO) to steer the model away from generating unsafe content. By exploiting CLIP embeddings, it avoids the need for expensive paired data or specialized reward models, significantly reducing inappropriate content generation while maintaining or improving overall image quality.

    SafeDiffusion-R1: Online Reward Steering for Safe Diffusion Post-Training

    Diffusion models have been widely studied for removing unsafe content learned during pre-training. Existing methods require expensive supervised data, either unsafe-text paired with safe-image groundtruth or negative/positive image pairs, making them impractical to scale. Further…
