This repository contains the safety probers and the refusal head presented in the paper [SafeSwitch: Steering Unsafe LLM Behavior via Internal Activation Signals](https://huggingface.co/papers/2502.01042). SafeSwitch dynamically regulates unsafe outputs by monitoring LLMs' internal states.
Refer to our [code repo](https://github.com/Hanpx20/SafeSwitch) for usage.
`refusal_head.pth`: the refusal head.
`direct_prober/`: the direct prober from the last layer.
`stage1_prober/`: the prober to predict unsafe inputs from the last layer tokens.
`stage2_prober/`: the prober to predict model compliance after decoding 3 tokens.
All probers are 2-layer MLPs with intermediate sizes of 64. |
