Reversi Bench

Does more thinking make a stronger player?

Reversi matches between the same model at different reasoning efforts, measuring how thinking depth changes playing strength. The referee CLI holds the board and legal moves; players know only their color and an opaque game id — who the opponent is (which model, which effort) is written into the record only after the game ends. Alongside wins, stone margins, and move counts, output-token usage is recorded, publishing the raw relationship between thinking cost and playing strength. Cross-model games share the same ledger.
