About this paper

Surya Narayanan Hari, Matt Thomson

Researchers at Caltech's Department of Biology and Biological Engineering developed Tryage, a system inspired by the human brain's thalamus, for real-time, intelligent routing of user prompts to specialized large language models. This system selects optimal models for individual prompts, achieving 50.8% accuracy in model selection and up to 17.9% performance gains over general models, while also enabling user-defined constraint-based trade-offs between accuracy and computational cost.

Key insights

  • Biological principles, such as the thalamic routing mechanism in the human brain, can inform the design of efficient, adaptive multi-model AI systems.
  • A dedicated language model can be trained to accurately predict the performance of downstream expert models on individual prompts, enabling dynamic and intelligent routing.
  • Such a routing system can implicitly learn to distinguish between diverse data domains, leading to interpretable and domain-aware routing decisions.
