A new approach by Nvidia has found a way to use GPT-4, the powerful language model behind ChatGPT, to enhance the capabilities of a Minecraft bot. GPT-4 is a neural network that can generate natural language texts based on a given input. It can also generate code and other types of data.
The Nvidia team, led by Anima Anandkumar, the director of machine learning at the company and a professor at Caltech, created a bot called Voyager that uses GPT-4 to solve problems and learn new skills inside the game. Voyager does not play the game like a human, but it can read the state of the game directly through an API. It can then use GPT-4 to generate objectives that help it explore the game and code that improves its skill over time.
For example, Voyager might see a fishing rod in its inventory and a river nearby, and use GPT-4 to suggest the goal of doing some fishing to gain experience. It will then use this goal to have GPT-4 generate the code needed to have the character achieve it. If the code initially suggested does not run perfectly, Voyager will try to refine it using error messages, feedback from the game, and a description of the code generated by GPT-4.
Over time, Voyager builds a library of code that helps it learn to make increasingly complex things and explore more of the game. A comparison with other AI agents shows that Voyager can gather three times as many items, explore twice as far and build tools 15 times faster.
What if we set GPT-4 free in Minecraft? ⛏️
I'm excited to announce Voyager, the first lifelong learning agent that plays Minecraft purely in-context. Voyager continuously improves itself by writing, refining, committing, and retrieving *code* from a skill library.

Leveraging the Power of GPT-4
The project demonstrates the potential of GPT-4 to do more than just talk. By using language models to generate code and objectives, Voyager can overcome some of the limitations of conventional AI training methods that require large amounts of data and human supervision.
GPT-4, or Generative Pre-trained Transformer 4, is a large language model (LLM) developed by OpenAI. It is the fourth generation of the GPT language model series, and it is significantly larger and more powerful than its predecessors.
GPT-4 was trained on a massive dataset of text and code, and it can generate human-quality text, translate languages, write different kinds of creative content, and answer your questions in an informative way. It is still under development, but it has the potential to revolutionize the way that AI is used in a variety of applications.
