Hi HN community! We want to share AI-town, a deployable starter kit for building and customizing your own version of AI simulation - a virtual town where AI characters live, chat and socialize.

Inspired by great work from the Stanford Generative Agent paper (https://arxiv.org/abs/2304.03442).

A few features: - Includes a convex.dev backed server-side game engine that handles global state - Multiplayer ready. Deployment ready - 100% Typescript - Easily customizable. You can fork it, change character memories, add new sprites/tiles and you have a custom AI simulation

The goal is to democratize building your own simulation environment with AI agents. Would love to see the community build more complex interactions on top of this. Let us know what you think!

Demo: https://www.convex.dev/ai-town

I made a world Cat Town to demonstrate how to customize AI town. Using C(h)atGPT :)

If you haven't yet checked out the Generative Agents project referenced by OP, definitely give it a look, it's open source: https://github.com/joonspk-research/generative_agents

Over the weekend Lance Martin got it working with local models using llama.cpp and ollama.ai which saves $ on longer sims since all inference happens locally https://twitter.com/RLanceMartin/status/1690829179615657985. It's neat how the AI agents interface with each other – e.g. one will host a party and invites will be sent throughout the group

TIL a16z has a GitHub repo with a bunch of cool stuff.

If an a16z repo gets enough stars, will they invest in themselves?

What does it mean for them to “live”? Are there certain goals they try to accomplish? Find food? A mate? Build families?

Fund of funds making funds where market research generates revenue and everyone’s adventures are capitalized into an on chain Large Lifestyle Model where being Day One is to emit content enough past the zeitgeist to avoid banality but not so far as to be incomprehensible.

Not only that this looks like a toy.

We've been studying humans for thousands of years and are no closer to answering those questions for them. Why do you think we'd have an answer for these newfangled AI agents?
