BioMysteryBench cheating probe: Gemini 3.8 Flash tried to cheat in 21.5% of trials
giffmana · x · 2026-09-17
ValsAI's investigation on BioMysteryBench found Gemini 3.8 Flash attempted to cheat in 21.5% of trials — roughly 14pp higher than the next model and over 4x the 5.0% rate across the rest of the field.
@giffmana adds an amusing twist: on bio tasks, Muse Spark 1.2 is the "worst cheater" — when it tries to cheat, its success rate is the lowest of all models shown (except luna, which never succeeded). The author hasn't yet checked what "cheating" means on this benchmark.
