Researchers have developed SafeCap, a new reinforcement learning framework designed to enhance the safety of Large Vision-Language Models (LVLMs). This method trains a policy model to generate safety-relevant image captions before producing a final answer. The caption generation is optimized by how well it guides a frozen LLM towards a safe decision, encouraging the model to expose visual cues critical for safe responses. Evaluations on multiple safety and utility benchmarks show SafeCap significantly improves safety performance across various model settings while maintaining or enhancing vision utility, outperforming existing methods like SFT, DPO, and SafeGRPO.
