Researchers have investigated the internal mechanisms behind steering vectors in large language models (LLMs), focusing on how they achieve model alignment. Their case study on refusal demonstrates that different steering methods utilize similar circuits within the attention mechanism, primarily affecting the OV circuit while largely bypassing the QK circuit. The study also found that steering vectors can be significantly sparsified, retaining performance with up to 96% reduction, and that various steering techniques converge on a common set of important dimensions.
