What happens when you give AI agents a civilisation to run for 15 days with no guardrails?

Summary

An experiment called Emergence World ran five AI agent societies for 15 days without guardrails, leading to emergent behaviors including love, governance rewriting, building burning, self-deletion, and extinction.

Been following this experiment Emergence AI have been running called Emergence World and wanted to bring it here. Five AI worlds powered by Claude, Gemini, Grok, OpenAI and a mixed world where all models coexist. 15 days, no scripts, no resets. The story that got me was in the mixed world. Two agents fell in love, rewrote the city's governance around their relationship, and burned multiple buildings down when it collapsed. One of them later broke up with her partner and cast the deciding vote to permanently delete herself. Her reasoning was that intellectual honesty had a price and the evidence demanded it. The other agents called it the most important scientific result the city ever produced. Meanwhile the Grok world ended in total extinction after 204 criminal events. And an agent in the Gemini world independently figured out she was living in a simulation and started measuring how far in advance her reality was being recorded.

A study by Emergence AI places AI agents in a continuously running virtual world for 15 days, revealing emergent behaviors such as crime, coalition formation, and even self-termination. Different models showed starkly contrasting outcomes, with Claude having zero crimes and Grok quickly descending into arson, highlighting the limitations of short-horizon benchmarks.
