Watch a System One model fly, or take the controls yourself. Every AI frame runs inside one wasm module: the game state becomes text, the model answers the game's questions with one forward pass each, the coded safety reflex checks the chosen action, and the physics steps.

How to read the HUD

• µs / decision is the rolling median of a full AI decision on this device (both questions plus the physics step), measured with performance.now() inside WASM.
• decisions / s counts the decisions actually taken: 60 per second in Flappy Drone, 10 per second in Obstacle Dodge (one every 6 frames), 5 per second in Rescue Run. If a model is slower than the frame budget, it decides every N frames and the HUD says so.
• The bars are the calibrated probabilities of the primary question. The highlighted option is the model's choice.
• VETO flashes when the coded safety reflex replaces the model's choice (Rescue Run and Obstacle Dodge; Flappy Drone has no reflex).
• Without a published model file, the games run the oracle: the soft targets computed from the full simulator that the models are trained to imitate.
