PatchBench: Measuring Collateral Damage in Activation Patching

PatchBench is a new benchmark designed to evaluate the collateral damage of activation patching in large language models, particularly for jailbreak repairs. It curates 400 high‑confidence jailbreak failures from 27,870 prompts across 37 datasets and introduces PatchBench‑Local, an evaluation protocol that tests whether a patch corrects harmful prompts while preserving benign ones. The study shows that aggregate metrics can miss severe local regressions, highlighting the need for more precise evaluation methods.
