How it uses Jev

Watch Jev , TypeSafe's System One model, play chess against any LLM on OpenRouter or against the Stockfish engine, or play Jev yourself. Every move is shown as it happens, with the moves Jev weighed and how likely it thought each one was, and every finished game is saved for replay.
