Efficient Safety Benchmarking via Item Response Theory
Quick summary
arXiv:2606.20626v2 Announce Type: replace-cross Abstract: Safety benchmarks for language models are typically evaluated using static paradigms that treat all items as equally informative for all models, an assumption that is particularly problematic for adversarial, highly heterogeneous safety items. Applied in full to modern benchmark suites, current evaluation procedures would require on the order of $10^5$ responses, most of which provide little ranking signal. We analyze six widely used safety benchmarks and make three contributions toward more efficient safety evaluation. First, we show t

Why it matters
“Efficient Safety Benchmarking via Item Response Theory” shows why AI risk cannot be reduced to answer accuracy. Access controls, logging, human approval and incident response need to be designed into the workflow from the start.
