Google's 4 Gemini 4 Argon agents beat Minecraft: 27 hours, 605 deaths, and about $520 spent.
According to a report from Bijie, four of Google's Gemini 4 Argon coding agents took on a challenge in Minecraft, spending 27 hours, dying a total of 605 times, and costing about $520. The researchers did not preassign roles; the four agents, in a randomly generated survival world, wrote and executed 2,783 JavaScript programs on their own and ultimately succeeded in defeating the Ender Dragon. They used the open-source library mineflayer to read coordinates and environmental information and to control the characters for mining and combat. The experiment showed that before completing the game, the model was called about 24,000 times, processed 1.35 billion input tokens, and achieved a 91% cache hit rate. The progress in this experiment lies in letting general coding agents plan and collaborate on their own to complete the game, but there are also limitations in the relatively low game difficulty and the convenience of obtaining information.
