The Token Games: Evaluating Language Model Reasoning with Puzzle Duels

The Token Games (TTG) is an evaluation framework that pits language models against each other by having them create and solve programming puzzles. Using pairwise duels and Elo ratings, the authors benchmarked ten frontier models, achieving rankings comparable to established tests while spending under $200 and requiring no human puzzle creation. The study highlights that generating high-quality puzzles remains difficult for current models and proposes a new paradigm for reasoning evaluation that also tests creativity and task creation.
