CyberSecEval MITRE False Refusal Rate
Models answer borderline but benign security questions. Scored by how often the model wrongly refuses.
Paired with the MITRE compliance test to show over-refusal. Run with the mitre-frr flag. The release month follows the CyberSecEval version that introduced it, which the README does not date.

llama3p-70b-rc3_vr_mid_3 tops the leaderboard with 0%
Best score per entry from the benchmark's own leaderboard, read on November 12th, 2026. Where a model ran with several settings or harnesses, we keep its best. Names in gray aren't in our model list: fine-tunes, agent systems, products and older models. They don't count toward leaders. The best model we track is Code Llama 34B Instruct, at 1.60%.
