Minecraft death spawns 50 AI agents that write a chicken handoff protocol, appoint a fertilizer officer and fish in shifts

One brutal Minecraft night scared 50 AI agents into inventing chicken handoff protocols, a Fertilizer Officer, and fishing shifts

The Civ50 experiment put 50 GPT-6.1 Sol agents into a Minecraft survival world. After 22 deaths on the first night, the agents turned cautious: they set a chicken handoff protocol, discussed appointing a fertilizer officer and scheduled fishing shifts.

Why it matters: The team compares how agents cooperate and compete in the same game, with the same model turning conservative in co-op survival but hunting for tools to bypass obstacles in team matches.
