Google's Gemini 4 Argon agents just cleared Minecraft's full progression chain with zero human hands on the keyboard or mouse. Four agents dropped into a random Easy survival seed, wrote their own JavaScript via Mineflayer, coordinated through in-game chat, and still needed 27 hours and 14 minutes plus 605 deaths to kill the Ender Dragon.

They self-organized fast: one handled tools and Nether fortress runs, another farmed food and supplies, a third lit portals, and the last built Enderman shelters while landing the final blow. They swapped 229 messages, ran 2,783 programs (22% errored out), and even recovered each other's dropped loot after deaths. The dragon itself killed them 69 times before one agent figured out stacking dirt to snipe the healing crystals.

Google calls it the first end-to-end autonomous Minecraft run using only standard tools and no pre-scouted seeds. The bill came to roughly $1,620 in API costs for 1.35 billion tokens. Human speedrunners do this in under seven minutes; these agents treated it like a multi-day corporate project.

The researchers frame it as practice for long-horizon real-world agent teams. The rest of us see four overpaid interns who finally delivered after burning through the entire petty cash drawer.
