New LLM safety judge test reveals unreliability in current evaluation methods

Researchers have introduced a new method called policy invariance to assess the reliability of LLM-based safety judges. This approach tests whether an LLM's safety verdicts are consistent regardless of how the evaluation policy is worded or modified. Experiments revealed that current LLM judges are highly sensitive to minor wording changes, leading to significant verdict flips on unambiguous cases, thus conflating agent behavior with prompt phrasing.
