Paper Explores Steering Category-Specific Refusal Directions in Language Models

A new arXiv paper examines safety alignment in language models, focusing on models fine-tuned to emit distinct refusal tokens that signal different categories of refusal before they answer. The authors investigate refusal directions tied to specific categories and how those directions might be discovered and steered. The abstract provided is truncated, so the full method and results are not available here.

Paper compares diff-in-means and INLP for finding refusal directions in LLMs

A preprint revisits the finding that refusal behavior in safety-tuned chat models is controlled by a single linear direction in the residual stream, which can be recovered by taking the difference in means between harmful and harmless activations. The authors compare this diff-in-means approach with INLP, an iterative nullspace projection method, to see whether a one-direction account holds up. The work is presented as a preliminary comparison of the two techniques.
