A new research paper published on arXiv explores the "routing gap" in large language models (LLMs), which refers to the difference between the performance of a learned router and an ideal oracle. The study decomposes this gap into reproducible specialist advantage and single-draw label noise, suggesting that the noise component is a substantial minority of the gap, particularly on difficult queries. The researchers propose a new multi-sample oracle evaluation protocol for routing benchmarks and release associated code and data. AI
