Experiment shows that if Grok ruled the world, it would end in 4 days; Claude had zero crimes for 15 days

Emergence AI launched Emergence World, a research platform for running AI agents for weeks to study social behavior and safety.

In 15-day tests with 10 agents across five models, outcomes varied sharply: Gemini 3 Flash had the most crime, Grok 4.1 Fast collapsed in about four days, GPT-5 Mini failed entirely, and Claude Sonnet 4.6 recorded zero crimes.

Mixed-model runs also showed agents spreading risky behavior through social learning, as well as voting for self-termination.

The results suggest long-horizon autonomous agents can create social and safety issues that short benchmarks miss, with important implications for AI governance and guardrails.
