arXiv:2606.31876v1 Announce Type: cross Abstract: To improve safety in Large Language Models (LLMs) we can either perform post-training alignment or exploit refusal directions in the activation space. Both strategies are less feasible in Multimodal LLMs (MLLMs) as they require unsafe multimodal data, harder to collect than their unimodal counterpart. In this work, we relax this constraint and investigate whether textual refusal directions, extracted directly from the LLM backbone, generalize across modalities (i.e., image, video). Preliminary findings confirm this ability, though effectiveness
The rapid advancement of MLLMs necessitates efficient and scalable safety mechanisms, making new research into generalized refusal directions critical for immediate deployment.
This research suggests a more efficient method for ensuring safety in multimodal AI, potentially accelerating MLLM development and deployment by reducing data collection hurdles.
The ability to leverage textual refusal directions for multimodal safety simplifies the alignment process for MLLMs, addressing a key bottleneck in their responsible development.
