Ask Jev a Choice per turn: which legal chess move to play.

Hassan's tweet is one filmed game of Jev versus GLM 5.3. There is no public repository. Distinct from Subway Surfers, which picks a lane and a move on a game overlay, and from the Sprite Fusion ninja runner, which fills the next terrain slice.

The tweet prints about 0.3 s and under $0.0001 per Jev move, about 5.8 s and about $0.008 per GLM 5.3 move, and 24 cents for the whole game. GLM 5.3 won by checkmate in 29 moves. The tweet does not print an Elo or an accuracy, so the metric row keeps those totals.

Hassan's takeaway is to use each model for its strength: Jev for fast, well-defined classification, an LLM such as GLM 5.3 when the call needs reasoning or lookahead, and a hybrid pipeline on real work, with Jev on the easy calls.
