Four Gemini 4 Argon coding agents defeated Minecraft’s Ender Dragon after writing 2,783 programs, researchers report in an announcement shared by Maxence Faldor. Their server log recorded the win 27 hours and 14 minutes after the first program. The experiment used general-purpose coding agents in a sandboxed survival world, rather than a system built specifically for Minecraft.
The team acted through code, not screenshots or keyboard controls. The researchers supplied the standard Mineflayer library, which exposes information about a player and the surrounding world and supports basic actions such as moving, mining and crafting. The agents divided work through game chat and shared memory without pre-assigned roles, kept notes, reused helper functions and recovered one another’s dropped items.
The setup matters when interpreting the result. The agents started in a random world on Easy, and a pathfinding plugin planned routes around obstacles. The researchers recorded 605 respawns and errors at the end of 22% of programs. This was not a demonstration of agents playing from pixels as a human would.
Researchers monitored a live dashboard and could pause or stop the run. They report that a fifth Observer agent and a manual review of a sample of the logs found no cheating or specification gaming. That remains the research team’s account of the experiment, not an external replication. The announcement also specifies that the study is not an official Minecraft milestone or approved by Mojang or Microsoft.
