 The Kagi Reasoning Benchmark is an **unpolluted reasoning benchmark** to assess large language models (LLMs) through diverse, challenging tasks. Unlike standard benchmarks, the tasks in this benchmark are unpublished, not found in training data, or "gamed" in fine-tuning. The task set changes over time (mostly getting more difficult) to better represent the current state of the art.
