You vs shad0w.
It decides every frame.
The right paddle is a real shad0w that learned to play Pong from an LLM's answers. It runs in your browser: no server, no network. Sixty times a second it reads the court and picks up, stay or down, in microseconds. Add balls, speed them up, shrink the paddles: it still decides in time.
Ready?
Move your mouse or finger over the court, or use W/S or the arrow keys. First to 7.

against other decision makers
The race against System One models is on the arena page.
There, shad0w and four other decision makers (a hosted LLM and three small decision models on an Apple M5 Pro's GPU) play the same snake games at speeds up to 120 moves a second. Recorded on an Apple M5 Pro (15-core CPU, 16-core GPU, 24 GB), with every number measured.
