Open-source agent beats Minecraft in 8 minutes 43 seconds
GPT-6 Astra plans the run with 35 calls, Jev picks actions from game state across 131 decisions, Mineflayer executes them, and code verifies the run with 17 checks, ending in a dragon kill via six bed explosions.
A DEV JUST OPEN SOURCED AN AGENT THAT BEAT MINECRAFT IN 8 MINUTES 43 SECONDS GPT-6 Astra plans the run, JEV picks every action The setup works for almost any agent you build, browsers, support bots, code review, ops The big model handles the plan, the small model handles individual actions, and code checks whether the action actually worked How it works: Astra sets the objective, item targets and a travel waypoint, using 35 calls for the entire run JEV picks one action from the current game state, travel, mine a block, craft, open a chest, eat, sleep or fight, making 131 decisions Mineflayer handles the pathing and sends each action through the normal player protocol, with no screenshots or key presses The dragon fight uses one bounded bed attack, which aborts if the player loses cover Code checks the run afterward with 17 run checks, 8 route, camera and screen checks, plus 29 local tests The run only counts as a win when there’s evidence of dragon death and the exit portal event It killed the dragon with six bed explosions on the first landing No deaths, no restarts, no operator fixes Astra plans, JEV acts, code verifies It used peaceful difficulty and a picked seed with 21 obsidian in chests and an active portal, with the seed coordinates provided The README describes it as a speedrun seed, not proof that this is the easiest possible seed Link to the agent repo in the comments
