A new benchmark called PatchBench has been developed to evaluate the effectiveness of safety patches in large language models (LLMs). The benchmark aims to identify instances where a patch might fix a specific harmful behavior but inadvertently cause regressions in other areas, such as refusing benign prompts or failing on slightly altered harmful prompts. PatchBench includes a curated set of 400 high-confidence jailbreak failures and an evaluation protocol, PatchBench-Local, designed to test for behavioral precision by examining harmful variants and benign neighbors of original prompts. Initial evaluations using PatchBench-Local revealed that while global capabilities might remain largely intact, significant local collateral damage can occur, highlighting the limitations of existing aggregate metrics for assessing LLM safety repairs.
