We sat 12 frontier models at a Mafia table for 40 games.
Every role, vote, lie, investigation, and night action was logged and scored.
When it came to detection, we found that @Kimi_Moonshot K3 was the best, figuring out the mafia 72.9% of the time while @claudeai Opus 5 was only able to do so 48.8% of the time.
