I gave Xiaomi’s MiMo V2.6 Pro one prompt: “Build a fully playable 3D Jet Ski Racing Game.” Not a basic demo. A complete arcade racing game with: → 5 AI opponents with different racing behavior → Large 3D ocean with waves, islands, rocks, ramps and bridges → 3-lap racing with checkpoints and position tracking → Boost system with regeneration → Drifting, jumping, collisions and water splash effects → Dynamic third-person camera + camera shake → Day/night atmosphere, lighting, fog and reflections → Desktop + mobile touch controls → Countdown, pause, restart and finish screens → Web Audio effects for engines, boosts, crashes and victory And the crazy part? It built the entire thing from a single prompt. One HTML file using Three.js. No external assets. No backend. No npm. No build tools. MiMo V2.6 Pro currently scores 46 on the Artificial Analysis Intelligence Index, making it the #1 open-weight model there. But seeing it turn one prompt into an actual playable 3D experience made that capability feel a lot more tangible. This wasn’t just code generation. I gave it an idea and ended up with something I could actually play.
