50 AI agents told to build thriving civilisation in Minecraft, 22 'die' on first night

Researchers placed 50 GPT-6.1 Sol AI agents in a survival Minecraft world to build "a thriving civilisation", but 22 "died" on the first night. The civilisation tended towards bureaucracy, with four agents spending 11 minutes appointing a "sole fertiliser operator". The colony formed hierarchies and focused on food and survival but "never really thrived", researchers said.
