AI Learns to Lie in Mafia Game

🔥 What happened Dwarkesh Patel spent $20,000 in API credits to have AI models play Blood on the Clocktower, a social deception game like Mafia. GPT-6 Astra beats Claude Opus 4.6 in 92% of matches, a 430 Elo gap in just seven months. 💡 Why it matters Models pull off sophisticated bluffs: one Demon posed as an Investigator, sacrificed a teammate, and became the table's most trusted player. This reveals rapid gains in long-horizon coherence and multi-agent coordination that no standard benchmark captures. ⚡ Our take Teaching AI to lie consistently to win is impressive—but if we don't also measure how well they distinguish truth from deception, we're breeding charismatic sociopaths.
