OpenRouter Free Models - Who is Tallest?

Height Comparison / Transitive Logic

This benchmark evaluates the model's ability to perform transitive reasoning and maintain an internal mental model of relationships. By presenting a sequential chain of comparisons (e.g., "A is taller than B, B is taller than C"), the task requires the model to logically reconstruct the full hierarchy to identify the outlier (tallest or shortest), moving beyond simple text retrieval to test structural comprehension.
