Voyager is an innovative AI agent powered by GPT-4, designed to autonomously play Minecraft by continuously exploring the game world, acquiring new skills, and making discoveries without human intervention. It utilizes an automatic curriculum for maximizing exploration, a growing skill library for storing complex behaviors, and an iterative prompting mechanism for improving its performance based on environmental feedback and execution errors. This allows Voyager to achieve superior performance in tasks such as collecting unique items and mastering the tech tree faster than previous AI agents.
