❯ Four Gemini 4 Argon agents complete Minecraft through autonomous collaboration in a 27-hour run

A shared task lasts more than a dayGoogle DeepMind researchers report in a paper released on October 15 that four Gemini 4 Argon agents defeated the Ender Dragon in a randomly generated survival world on Easy difficulty after 27 hours and 14 minutes. They ran 2,783 programs and died 605 times, without human-assigned roles or mid-run guidance.

Code controls the charactersThe agents write JavaScript using the Mineflayer open-source library to move, mine, craft and read environmental information, rather than operating a keyboard and mouse from screen images. The library supplies action interfaces without choosing the next task. Through game chat and shared memory, the agents gradually divide responsibilities such as gathering, crafting, exploration and combat.

Coordination survives repeated failureThe team exchanged 229 messages and recorded coordinates, tool problems and tactical lessons. The paper says an independent observer agent and human review of sampled logs found no cheating. Six server restarts occurred during the run. The result demonstrates sustained coordination and recovery rather than uninterrupted technical operation.

One success leaves reliability unmeasuredThe authors explicitly describe a single run on the first attempt, which cannot establish a success rate. A programmatic game interface also differs from human operation and real-world robotics. The research provides a recorded long task for studying collaboration, memory and persistent execution, informing how more complex software work might be evaluated.

▮ SIGNALLong tasks expose whether agents can retain goals, exchange useful information and resume collaboration after failure.
