Games
Small games with simple rules. Some play with light and colour, some with physics or strategy, one with keeping AI agents safe. All of them are free to play in the browser on sofi.games.
AI safety
Little Agent Lab
Build a crew of eager little AI agents, hand out keys, test your plan with a decoy, then go live and keep the secret blueprint inside. Eight levels, each based on a lesson from a real 2026 incident where AI agents escaped their sandbox.
