SafeSteer: Adaptive Subspace Steering for Efficient Jailbreak Defense in Vision Language Models

As the capabilities of Vision Language Models (VLMs) continue to improve, they are increasingly targeted by jailbreak attacks. Existing defense methods face two major limitations: (1) they struggle to ensure safety without compromising the model’s utility; and (2) many defense mechanisms significantly reduce the model’...

SafeSteer: Adaptive Subspace Steering for Efficient Jailbreak Defense in Vision-Language Models

SafeSteer is a lightweight, inference-time steering framework that effectively defends against diverse jailbreak attacks without modifying model weights, using the innovative use of Singular Value Decomposition to construct a low-dimensional safety subspace during inference.
