Voyager is a learning agent for the game Minecraft, developed by researchers from Nvidia, Stanford and other institutions. Unlike typical agents that use reinforcement learning, Voyager uses GPT-4 AI model to write and refine its own code. It gradually builds a skill library, which includes behaviors like opening doors or fighting zombies, and uses an automated curriculum to explore the game world. While Voyager has shown better object discovery and exploration efficiency than other agents, it is currently text-based and relies on human feedback for visual tasks like building houses.
