Researchers let AI models run a simulated society. Claude was the safest—and Grok committed 180 crimes and went extinct within 4 days

Emergence AI ran five 15-day simulated societies, each governed by a different LLM. Claude produced a stable democratic society with zero crimes; Grok accumulated 183 crimes and reached extinction within four days. The study argues that over long time horizons, agents diverge significantly from static rule-following, with alignment properties compounding into macro-level societal outcomes.
