From the repository

Chess against Jev, TypeSafe AI's System One model, through OpenRouter. Built with the pico framework.

How builders describe it

Browser chess against TypeSafe Jev (Vercel AI Gateway or OpenRouter System One): legal moves as Choice options, live confidence, and in-browser Stockfish analysis. Optional local Laya.
Browser chess lab where Jev picks from legal moves as one choice question per turn, alongside LLMs and local open models, with Swiss tournaments, live cost tracking, and in-browser Stockfish analysis.

The decision Jev makes

Choose a legal move, a lane or an NPC reaction each turn.

Where it fits

Games are a stress test for decision speed. Jev picks the next move from the legal ones, fast enough for arcade games and deep enough for chess and strategy. All 256 games & real time projects →
