Four AI agents killed the Ender Dragon after 27 hours and 14 minutes, 605 deaths and 2,783 JavaScript programs. No human stepped in at any point.
The agents ran on Gemini 4 Argon and came from a Google DeepMind team. The run was fully autonomous from start to finish, which makes it the first time Minecraft has been beaten with no human input.
The team used a randomly generated world. It handed out no roles or strategies, and the agents had no tools built for Minecraft. Once they dropped in, every decision was theirs.
The agents organized themselves
Nobody told them how to divide the work, so they sorted it out themselves. They flagged threats to one another and picked up the items of teammates who died, which was a regular event.
Mistakes went into a shared memory. Across the whole session, the four agents sent each other 229 chat messages. For a 27-hour project that is not much conversation. It could mean tight coordination, or it could mean a group that mostly worked solo and only checked in when needed.
A $1,620 dragon
At the standard Gemini 4 Argon price, which kicks in during 2027, the run cost $1,620. Divide that by 605 deaths and it adds up to an expensive lesson in why you shouldn’t dig straight down.
The price tells you more than the stunt does. A few years back, an AI needed to be purpose-built and trained from scratch to beat a game like this. Minecraft is now the newest game cleared by general-purpose agentic models, which had no game-specific setup and wrote their own code along the way.
