New framework SafeNexus targets safety neurons in MLLMs

Researchers have developed SafeNexus, a new framework designed to enhance the safety of Multimodal Large Language Models (MLLMs). This framework identifies and manipulates specific neurons, termed "safety neurons," which are crucial for regulating model behavior across different modalities. By targeting these modality-universal safety neurons (US-Neurons), SafeNexus aims to improve defenses against cross-modal threats while preserving the model's overall utility. The approach involves localizing these neurons through activation patterns and then employing strategies like activation amplification and selective fine-tuning to bolster safety. AI

IMPACT Enhances safety mechanisms for multimodal AI, potentially improving robustness against cross-modal threats.
