Four AI agents powered by Google’s Gemini 4 Argon defeated Minecraft’s Ender Dragon without human intervention, completing the task in 27 hours and 14 minutes. Google DeepMind researchers placed them in a randomly generated survival world on Easy difficulty, with cheat commands disabled. Although their objective was specified, they received no assigned roles, strategy or custom game-specific tools. Rather than viewing the screen or operating a keyboard, they controlled individual players by writing JavaScript programs through the open-source Mineflayer library.
The agents independently divided responsibilities, manufactured tools, gathered supplies and exchanged warnings, coordinates and lessons through chat and shared notes. They also recovered teammates’ belongings after deaths. Across the run, they produced 2,783 programs, exchanged 229 messages and died 605 times. The battle in the End lasted nearly 14 hours. About 21 hours into the experiment, one agent recognized that ten crystals were restoring the dragon’s health. Destroying them took another four hours and 40 minutes; the dragon fell 39 minutes later.
The achievement nevertheless carries qualifications. Mineflayer supplied exact information about nearby blocks and creatures, even behind solid rock, and a plugin handled route planning. Roughly 22% of programs ended in errors, and the findings reflect a single run. A fifth agent monitored for cheating and detected none, while researchers never needed to exercise their ability to pause or stop the session. The entire session, including monitoring, cost an estimated $810 at introductory pricing, or $1,620 at standard rates. Earlier community projects reported dragon defeats, but used game-specific tools or a fixed, easier setup.
