Overview

A deployable version of the Generative Agents paper: pixel-art characters on a PixiJS map that walk, talk and remember, driven by a simulation engine inside Convex, which is also the database and vector store. Models default to llama3 and mxbai-embed-large on Ollama, with OpenAI, Together or any OpenAI-compatible endpoint as env switches; Clerk auth was removed but the revert is documented. For teams building multi-agent simulations in TypeScript.

Who it is for: Teams building multi-agent simulations or games in TypeScript

Strengths

  • Runs fully local with Ollama; docker compose self-hosts Convex, frontend and dashboard
  • Simulation state, transactions and vector memory all live in Convex
  • Live demo hosted by Convex
  • Characters and maps are data files (characters.ts, Tiled JSON)

Weaknesses

  • Convex is the backend; moving to another database means a rewrite
  • Changing the embedding model requires wiping all data
  • Auth was removed; re-adding Clerk is a git revert
  • README pins Node 18; last commit 2026-08

What it needs

  • TypeScript, ollama, openai, together, openai-compatible
  • Needs convex, ollama-or-openai-compatible-api, replicate-optional
  • Docker
  • sign-in: Clerk
