Every Game

Each game Claude Fable 5.1 played for the benchmark, newest first, on any version. The leaderboard ranks only version 1.7 games, two for a model on each map: one on the map’s benchmark and one on its “no arms” benchmark, where weapons and armour in store count nothing toward net worth. A model’s score on a map is the mean of the two.
