Who should care:Researchers & Academics

OmniSteer addresses cross-modality vulnerabilities in OLLMs using AdvBench-Omni dataset and modality-semantics decoupling. Uncovers mid-layer dissolution and extracts golden refusal vector via SVD. Boosts refusal rate to 91.2% while preserving capabilities.

Key Points

  • 1.Handles cross-modal safety risks
  • 2.Refusal rate from 69.9% to 91.2%
  • 3.Lightweight adapters for adaptive intervention

Impact Analysis

Strengthens OLLM safety without degrading multimodal performance.

Technical Details

SVD for pure refusal direction. Adapters modulate intensity dynamically.
