AI agents defeat Minecraft Ender Dragon using dual-model strategy

Engineer Ronak Malde has demonstrated a specialized AI agent capable of defeating the Ender Dragon in Minecraft in 8 minutes and 43 seconds. The experiment utilizes a dual-model approach combining OpenAI’s ‘GPT-6 Astra’ and TypeSafe AI’s ‘Jev’.

The system functions through a division of labor: Astra acts as a high-level planner (System 2 thinking) to determine long-term goals, while Jev serves as a rapid decision-maker (System 1 thinking) to execute immediate actions like moving, digging, or attacking. This architecture allows the agent to maintain continuous movement while the larger model processes the next strategic step.

Developed by TypeSafe AI CEO Diogo Almeida, a former OpenAI researcher, Jev is designed to bridge the gap between conversational AI and task automation by providing high-speed, structured decision-making rather than text generation. The total cost for the Minecraft run was less than $1.
