Output Loop Bench · Artifacts
Simulation: AI models compared
Physics and motion that must behave correctly. 29 models tested on the same task.
Balls in a rotating hexagon
The best-known public physics test. Weak models let balls pass through the walls; strong ones get collisions and the moving walls right.
