New metrics assess meaningfulness of language model routing policies

Researchers have developed a new framework for evaluating language model routing policies, focusing on behavioral differentiation and stability rather than just task accuracy. They propose adapting Hierarchic Social Entropy (HSE) to measure agent diversity and a perturbation-based metric for robustness. Applying these to EmbedLLM and RouterBench, they found that a small subset of agents can capture most of the available diversity, and that while KNN routers improve accuracy with specialist societies, they lack robustness, unlike prompted routing.
