Four Gemini 4 Argon agents beat Minecraft's Ender Dragon autonomously in 27 hours

A Google DeepMind team placed four Gemini 4 Argon agents in a sandboxed Minecraft survival world with one goal: defeat the Ender Dragon.

Each agent controlled a player via the open-source Mineflayer library and coordinated through in-game chat and shared memory; no roles were assigned and no game logic was written by humans — agents planned, wrote, and debugged every program themselves
Starting from a randomly generated world on Easy difficulty, the team wrote 2,783 programs and defeated the dragon in 27 hours 14 minutes, dying 605 times along the way
To the authors' knowledge, this is the first end-to-end autonomous completion of Minecraft by AI agents, using only standard Mineflayer — no pre-scouted seeds or human-written game-specific tools
Winning required keeping a coherent plan across thousands of dependent steps for over a day — the same long-horizon coding and multi-agent coordination demanded by real-world software engineering. The write-up details the setup, the run, team strategies (task division, knowledge sharing, item recovery), and limitations
