Show HN: GPT Clicker. An idle game about building an AI empire

mromanuk Thursday, December 18, 2025

I built an idle/clicker game about the AI hype cycle, because I love following how AI develops and also love idle games. You start circa 2018 with a laptop and a transformer idea, training your first model. The game follows "real" AI history: Attention Is All You Need → GPT-1 → you get the idea.

Core loop: - Train models (click or auto) to improve quality - Serve users to earn money - Buy hardware: from a used GTX 1060 to Dyson Sphere compute arrays - Research to unlock bigger models - Balance energy/compute resources Built with SolidJS + TypeScript + Vite. ~90KB gzipped. No frameworks, no backend, runs entirely in the browser. Saves to localStorage. The progression takes ~2-3 hours to reach ASI if you're actively playing, longer if idle. Hardware scales from 1 compute/sec (laptop) to 100M compute/sec (Matrioshka Brain). I tried to capture the exponential feeling of the AI scaling laws - each era feels faster than the last, which mirrors the real industry, but I didn't want to get into politics, corp, and stuff like that at this moment.

Would love feedback on game balance and pacing. The late game might be too fast or too slow depending on your playstyle.

Hope nobody get too mad at this, remember it's a parody, just a clicker game. And yes, it was made with an agentic LLM (I refuse to say vibe coded).
