One prompt builds an AI datacenter simulator: start with $10M, run H100 racks

The author vibe-coded a browser game, "AI DATACENTER SIMULATOR," using WorkBuddyAI's Hy4 model. You start with $10M, buy H100/H200/B200 racks, take on inference workloads from AI coding startups to voice/video companies, and manage power and cooling while racing to $1M monthly revenue before going broke or melting the datacenter. Every workload pushes GPU utilization, power, temperature and revenue, with heat as the core mechanic.

The post includes the full reusable prompt (visible 3D heat buildup, random events, win/lose states), doubling as a fun way to learn inference economics and a test of how far models have come at Three.js game dev.
