Geometry of LLM Refusal (April 2026)
Independent research (with 3 teammates) investigating whether LLM refusal behavior is mediated by a single direction or a cone in activation space. Extracted refusal directions in PyTorch across 4 harm categories on Qwen-1.8B-Chat using SORRY-Bench prompts, then used activation steering to identify layer 14 as the strongest refusal layer, achieving 84-96% cross-category ablation bypass rates and 0.735-0.892 cosine similarity, supporting a conic subspace framing over a single-direction hypothesis.
