50 AI agents built a rationing government in Minecraft, then huddled in shelters after a deadly first night
We ran AI agent swarms in Minecraft and Mindustry
YC Labs and Olam Labs ran 50 GPT-6.1 Sol agents in a survival Minecraft world for three hours with one goal: build a thriving civilization. They harvested nearly every reachable tree in 90 seconds, crowned the first agent in the directory as leader, and wrote shared plans and permits. Then the first night killed 22 agents, and the colony turned risk-averse, shifting from expansion to food rationing and shelter.
Stop optional bulk excavation/building and distant scouting. Idle in lit closed shelters until assigned short productive tasks.
