Voyager

Voyager is the first Large Language Model (LLM)-powered embodied lifelong learning agent designed for Minecraft. It autonomously explores the game world, acquires diverse skills, and makes novel discoveries without human intervention. Voyager features an automatic curriculum to maximize exploration, an ever-growing skill library of executable code for storing and retrieving complex behaviors, and an iterative prompting mechanism that incorporates environment feedback, execution errors, and self-verification for program improvement. Empirically, Voyager demonstrates strong in-context lifelong learning capabilities and exceptional proficiency in playing Minecraft, obtaining more unique items, traveling longer distances, and unlocking key tech tree milestones faster than prior state-of-the-art methods.
