Four Gemini agents finish Minecraft with no human help

Researchers say four agents wrote their own code for 27 hours to beat the Ender Dragon, on the game’s easy setting.

Four AI agents running Google’s Gemini 4 Argon model have finished Minecraft by defeating its final boss, the Ender Dragon, with no human help, a new paper says. The authors, Maxence Faldor, Satinder Singh and Roberta Raileanu, believe no AI team has finished the game alone before. The Decoder covered it on Sunday 18 October 2026 and names the team as Google DeepMind’s.

The agents got one goal and nothing else. They chose their own jobs, wrote every program and fixed their own bugs. Each one moved its player through Mineflayer, a free, open-source code library, and they kept each other informed by in-game chat and a shared memory. Researchers had a live dashboard and a stop button and never used either.

Dying was routine: 605 deaths before the dragon fell. The team wrote 2,783 programs in a randomly generated world on the Easy setting. It split up work and picked up fallen teammates’ gear, and the win came after 27 hours and 14 minutes. At Argon’s standard price, which applies from 2027, the run cost $1,620, The Decoder reports.

A day-long run without a lost thread is the skill long software and office tasks need from agents, the authors argue.
