Four Gemini 4 Argon agents defeat Minecraft without human help

Four AI agents running on Google's Gemini 4 Argon model defeated Minecraft's Ender Dragon in a fully autonomous run, writing 2,783 JavaScript programs and exchanging 229 messages over 27 hours and 14 minutes. The agents split tasks, warned each other of threats, and recovered items from dead teammates without pre-assigned roles or game-specific tools. The experiment cost $1,620 in compute credits at the standard Gemini 4 Argon rate effective in 2027.
