What it does
The maker’s October 2 report records 570 games without a win. Its no-model baseline reached the same deepest dungeon level, so that result does not establish a Jev advantage.

How you can use it
Borrow the split between choosing and acting for a game bot: ordinary code lists legal moves, Jev selects one, and a separate part presses the keys. Running this bot needs a local software setup and paid model access; it is not a ready-to-play browser game.
Use the dashboard to inspect each move’s alternatives, probabilities, history and spending. It supports pausing and stepping one turn at a time. Compare the decisions with the included no-model mode, which simply takes the first option, before attributing better play to Jev.
