About Voyager

Voyager is the first LLM-powered embodied lifelong learning agent in Minecraft that continuously explores the world, acquires diverse skills, and makes new discoveries without human intervention. It combines an automatic curriculum that maximizes 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. Voyager interacts with GPT-4 via blackbox queries, avoiding any model fine-tuning, and outperforms prior methods on unique items collected, distance traveled, and tech tree milestones.

Commonly Cited Strengths & Limitations

Strengths

Obtains 3.3x more unique items than prior SOTA
Travels 2.3x longer distances than prior SOTA
Unlocks key tech tree milestones up to 15.3x faster than prior SOTA
Generalizes learned skills to solve novel tasks in a new Minecraft world
Bypasses the need for model parameter fine-tuning
Alleviates catastrophic forgetting

Limitations

Heavily dependent on GPT-4; GPT-3.5 and open-source LLMs cannot provide the needed code quality (fails at even basic tasks)
Learns in isolation, neglecting social context of human-like learning
Self-verification is a vulnerability, as GPT-4 judging its own success can degrade reliability
Does not solve 3D perception or sensorimotor control, relying on high-level APIs
Due to Mineflayer's limitations, the bot's in-game view cannot be directly captured (viewer quality is poor)

Common Use Cases

Playing Minecraft
Lifelong learning in open-ended worlds
Self-driven exploration and skill discovery
Zero-shot generalization to novel tasks
