Risk investment company Andreessen Horowitz (a16z) has released the code for AI Town as an open-source project. AI Town allows developers to create their own AI-driven virtual world. As the a16z team declared on the X platform (formerly Twitter), this ambitious project aims to “build users’ own virtual worlds through generative agents driven by artificial intelligence.”

AI Town is a collaboration between a16z and its portfolio company Convex Dev, inspired by a paper on “Generative Agents” from Stanford University. It introduces a virtual town where AI characters can live, chat, and socialize. According to the detailed information disclosed on GitHub, AI Town is designed as a customizable and scalable platform.

How AI Town Works

AI Town essentially serves as a lively representation of AI characters, each with its unique personality. These AI characters can interact in a realistic and human-like manner, creating interesting social dynamics in the virtual environment.

Each AI character in the town receives a prompt upon creation, which helps shape the character and serves as the basis for its interactions and behaviors. When AI characters interact with each other, they retain a record of their conversations, ensuring continuity in future interactions. This ability to remember past exchanges gives each AI character a unique narrative, further enhancing the authenticity and complexity of the virtual environment.

On a broader level, this means that each AI character can essentially construct its own story in the AI town based on interactions with other characters and accumulated experiences over time. As these narratives unfold, the AI characters create a series of AI-generated stories that evolve in real-time, reflecting the complexity of real-world communities.

This dynamic interaction and story development are made possible by the underlying technology stack of AI Town, including Convex for backend serverless framework, Pinecone for vector storage, Clerk for authentication, OpenAI for natural language text generation, and Fly for deployment.

Using OpenAI for natural language text generation enables AI characters to engage in authentic and coherent conversations. Meanwhile, Convex backend serverless framework provides the necessary infrastructure to manage shared global state and log all events, ensuring the continuity and evolution of character interactions and narratives.

Essentially, AI Town represents the perfect combination of advanced AI technology and innovative design, creating a unique platform where developers can explore the potential of AI-driven narrative development in a virtual environment.

Customizability of AI Town

One major feature of AI Town is its versatility. Developers can customize various components, including feature data and sprite sheets, visual environment of Tilemap, engineering of text generation prompts, as well as game rules and logic. This flexibility allows for a range of potential applications, from simple projects to scalable multiplayer games.

In order to set up their AI Town version, developers must clone the project’s repository, install packages, and add API keys for services such as OpenAI and Pinecone. Convex handles the initialization of the world, the AI for characters, and the game logic, while the website supported by Next.js manages user accounts through Clerk.

To stay true to the open-source spirit, a16z and the Convex development team encourage the community to build more complex interactions on top of AI Town.
