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.

This project was intended to make it easy for anyone to create custom simulations and my attempt to recreate Generative Agents: Interactive Simulacra of Human Behavior. I’ve been working on Smallville…

We've just launched our new, three-headed API (part of which is an open WebSocket server) and we'd like to thank this community for the all the help, feedback and inspiration. Ducksboard launched as a Show HN and countless hours that should've been dedicated to developing the product went into browsing the site (until we discovered noprocrast, yay!) For the next 24 hours we're giving away free, full-featured plans to everyone with a HN account more than 10 days old, sign up at https://app.ducksboard.com/signup/hn/ These plans will always be free, but we can't promise we won't try to upsell…
