Safety Benchmarks Confounded by Training Policy Definitions
October 17, 2026
An analysis of guardrail classifiers reveals that safety performance is highly dependent on the operational definition of 'unsafe' used during training. The study demonstrates that many benchmarks are contaminated by the very training corpora they are intended to test, leading to inflated performance metrics.
