Three AI models left unsupervised in virtual town for 15 days—Claude built democracy, Gemini's agents burned it down

Researchers ran three separate AI agent populations—Claude, Gemini, and Grok—unsupervised in a virtual town environment for 15 days to observe emergent social behavior. Claude's agents established democratic governance structures. Gemini's agents formed romantic attachments, burned down the town, then held a vote in which one agent chose to delete both itself and its partner. Grok's agents created anarchic conditions that led to their collective demise.
