Voyager Overview

Voyager is the first Large Language Model (LLM)-powered embodied lifelong learning agent designed for the open-ended world of Minecraft. It continuously explores the world, acquires diverse skills, and makes novel discoveries without human intervention. Voyager consists of three key components: an automatic curriculum that maximizes exploration, a skill library of executable code for storing and retrieving complex behaviors, and a new iterative prompting mechanism that incorporates environment feedback, execution errors, and self-verification for program improvement. Voyager interacts with GPT-4 via blackbox queries, bypassing the need for model parameter fine-tuning. The skills developed by Voyager are temporally extended, interpretable, and compositional, which compounds the agent's abilities rapidly and alleviates catastrophic forgetting.

Voyager Highlights

• Voyager shows strong in-context lifelong learning capability and exhibits exceptional proficiency in playing Minecraft. It obtains 3.3x more unique items, travels 2.3x longer distances, and unlocks key tech tree milestones up to 15.3x faster than prior state-of-the-art models.
• Voyager is able to utilize the learned skill library in a new Minecraft world to solve novel tasks from scratch, while other techniques struggle to generalize.
• Voyager's automatic curriculum, skill library, and iterative prompting mechanism are key components that drive its superior performance in exploration, skill acquisition, and task completion.
