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.
