Four Gemini 4 Argon agents beat Minecraft with no human help

A Google DeepMind team reports that four AI agents running on Gemini 4 Argon beat Minecraft without human input, ending a fully autonomous run by killing the Ender Dragon. According to The Decoder's account of the paper by Faldor et al., the agents were placed in a randomly generated world with no assigned roles, strategies or game-specific tools. They divided the tasks among themselves, warned each other about threats, recovered items from teammates who had died and recorded mistakes in a shared memory. The run took 27 hours and 14 minutes. In that time the four agents wrote 2,783 JavaScript programs, exchanged 229 chat messages and died 605 times. The whole session cost $1,620 at the standard Gemini 4 Argon price that takes effect in 2027. The result adds to a series of cases in which general-purpose agentic models complete video games that, a few years ago, needed AI systems built and trained specifically for them. It also shows several model instances coordinating on a long, open-ended goal with only shared chat and memory, and it gives a concrete measure of the time and compute such coordination currently takes.
