AI agent swarms build a civilization in Minecraft: 50 agents descend into bureaucracy

ycombinator and Olam Labs tested AI agent swarms in Minecraft: 50 GPT-6.1 Sol agents were tasked with building a thriving civilization within 3 hours, but after a zombie attack on the first night, many tasks were abandoned, and 4 agents spent 11 minutes appointing a "sole fertilizer" for the bone meal on a single wheat block. In Bed Wars, 10 GPT-6.1 Sol faced 10 Claude Opus 5.5, and the GPT side won 6-1; Mindustry tests showed that GPT behaves more like swarm collaboration, while Claude is led by a single leader but adopts democratic decision-making. The related swarms have been open-sourced.
