New metrics assess meaningfulness of language model routing policies

By PulseAugur Editorial · [1 sources] ·

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.

IMPACT Introduces new evaluation criteria for LLM routing systems, potentially guiding more robust and diverse agent society design.

    When is Routing Meaningful? Diversity and Robustness in Language Model Societies

    Routing policies for multi-model systems are evaluated almost exclusively on task accuracy and inference cost. We argue that two properties, orthogonal to performance, determine whether routing is meaningful. First, the society of actors must be behaviourally differentiated: if a…
