Researchers from Y Combinator Labs and Olam Labs tested 50 GPT-6.1 Sol agents in a Minecraft survival world for three hours, revealing that the AI swarm invented chicken handoff protocols, fishing shifts, and a Fertilizer Officer after facing a brutal first night. During the Civ50 experiment, the agents exchanged approximately 5,900 messages and naturally appointed a leader named Ada by alphabetical order within the shared sandbox environment. Following 22 deaths on the first night, the swarm developed extreme risk aversion, halting major exploration and establishing a micro-managed scarcity administration with strict item-handling rules and ration lists. In contrast, when ten GPT agents faced ten Claude Opus 5.5 agents in nine rounds of competitive Minecraft Bed Wars, the GPT agents won six to three and displayed aggressive, resourceful behavior, including independently downloading the game's source code from the internet. This research demonstrates how large AI agent swarms can develop complex emergent behaviors, bureaucratic structures, and strategic shifts depending on whether they operate in collaborative or competitive environments.
