Starting from an empty inventory in a Java Edition 1.16.5 world, the agent reached the End and killed the Ender Dragon with a bed explosion in 8 minutes 43 seconds. Jev was called 131 times, Astra 35 times, and model costs ran about $0.01 for Jev and $0.96 for Astra.","whyItMatters":"The run is a working test of splitting an AI agent into a slow planner and a fast decision-maker, with Jev making the moment-to-moment calls and Astra setting the goal in the background.","webCardHtml":"\u003cp\u003eThe two models were given separate jobs. Astra sets the goal, something like preparing gear and heading for the End. Jev takes the current position, inventory, surroundings, and that goal, then picks one action from candidates such as move, dig, pick up, craft, and attack. Actual movement and mining go through the Minecraft bot library Mineflayer. Malde described the setup as a division of labor among a long-term planner, an instant decision layer, and conventional software that operates the game.\u003c/p\u003e","blueskyPost":"The 8:43 split hides the cost model: Astra ran 35 times at $0.96, Jev 131 times at about $0.01. Deliberation is the expensive half of the duo, and Malde's logging makes that ratio visible.","twitterPost":"Astra ran 35 times for $0.96; Jev ran 131 times for about a cent. The deliberation is where the money went.","threadsPost":"Astra was called 35 times and cost about $0.96. Jev was called 131 times and cost roughly a cent. The Minecraft run's interesting number is the call ratio: the agent that deliberates is the expensive half, and Jev does the repeated execution work cheaply.","newsletterBlurb":"Engineer Ronak Malde published a Minecraft experiment where an AI agent beat the Ender Dragon in 8 minutes 43 seconds using a bed explosion. The agent splits the work between OpenAI's GPT-6 Astra for planning and TypeSafe AI's Jev for fast action choices, with Mineflayer handling movement and mining. Jev was called 131 times and Astra 35 times, for model costs of about $0.01 and $0.96.","attributionJson":"[{\"source\":\"ASCII.jp\",\"url\":\"https://ascii.jp/elem/000/004/436/4436545/?rss\",\"title\":\"Minecraft's Final Boss Defeated in 8 Minutes 43 Seconds: The Division of Labor Between \\\"Thinking Astra\\\" and \\\"Instantly Deciding Jev\\\" Is Fascinating\"}]","lintFlagsJson":null,"lintHits":0,"costUsd":0,"inputTokens":4729,"outputTokens":637,"status":"published","repairAttempts":0,"nextRepairAt":null,"factsAttemptedAt":1789947861,"createdAt":"2026-09-20T23:38:42.000Z","publishedAt":"2026-09-20T23:43:20.000Z","updatedAt":"2026-09-20T23:43:20.000Z"},"cluster":{"id":"c_580648eb2743e25b401e82e8","canonicalTitle":"マイクラのラスボスを8分43秒で討伐　「考えるAstra」と「即断するJev」の分業が面白い","representativeArticleId":"a_5b34c1b6471a789e1bc4b587","sourceCount":1,"writtenSourceCount":1,"writeAttempts":0,"isSolo":true,"entitiesJson":"{\"anime_titles\":[],\"manga_titles\":[],\"work_titles\":[\"Minecraft\"],\"studios\":[],\"people\":[],\"type\":\"news\",\"domain\":\"games\",\"is_roundup\":false}","contentType":"news","status":"published","firstSeenAt":"2026-09-20T22:50:00.000Z","lastSeenAt":"2026-09-20T22:50:00.000Z","updatedAt":"2026-09-20T23:43:20.000Z"},"attribution":[{"source":"ASCII.jp","url":"https://ascii.jp/elem/000/004/436/4436545/?rss","title":"マイクラのラスボスを8分43秒で討伐　「考えるAstra」と「即断するJev」の分業が面白い"}],"entities":{"anime_titles":[],"manga_titles":[],"work_titles":["Minecraft"],"studios":[],"people":[],"type":"news","domain":"games","is_roundup":false},"keyFacts":null}
