Google's DeepMind team deployed four Gemini 4 Argon AI agents in a randomized Minecraft survival world with no human intervention or pre-assigned roles. Using only the open-source Mineflayer library, the agents coordinated via in-game chat and shared memory to defeat the Ender Dragon. They autonomously split tasks: one crafted tools, another gathered food, a third lit a key portal, and the fourth built shelters and delivered the final blow.
The agents warned each other of threats, shared tips, recovered items from dead teammates, and adapted through experience. Over 27.23 hours, they wrote and ran 2,783 programs, exchanged 229 messages, and died 605 times. A fifth 'Observer' agent monitored for cheating and published reports.
The effort consumed 1.35 billion input tokens, costing $810 at list price or $1,620 standard. Researchers called it the first end-to-end autonomous Minecraft completion by AI agents without human-crafted tools or pre-scouted seeds, highlighting the agents' ability to maintain coherent plans across thousands of dependent steps for over a day.
