Fast enough to play.
A game gives every decision a few milliseconds. shad0w learned each of these from an LLM's answers, then plays where speed decides who wins: two you can play in your browser, two recorded races against LLMs and System One decision models. And one that isn't a game: a live minute of Polymarket, every trade labelled as it lands.
