What it does
Because every option is legal by construction, Jev cannot play an illegal move — the failure that sank earlier LLM attempts at Go. Beating it puts your name on a hall of fame.
Apps & data pipelines
Jev, go.
Play Jev at Gomoku, Go or chess: code builds a pool of legal candidate moves and Jev answers one Choice over them, with every call shown under the board.

How you can use it
You can sketch the rules of a turn-based board game for your project. A developer can write code that checks the board, filters out illegal moves, and handles obvious plays like immediate wins or forced blocks on its own.
Your developer can then send up to twelve safe, valid moves to Jev. The model picks the best option from that specific list, so it will never suggest an impossible move or make things up.
