The article explains how to create an inexpensive yet dependable model router using Jev, highlighting that model routing can now be considered a design decision rather than merely a system improvement. It outlines the steps and benefits of implementing this approach, emphasizing its practicality and cost-effectiveness. The piece serves as a guide for developers looking to integrate efficient model routing into their workflows.

The paper introduces SaveRouter, a sparse‑supervision framework for large language model routing that selectively gathers informative model feedback and shares capability information across related queries. By using only about 33–41% of available training feedback, SaveRouter achieves competitive or superior routing quality while reducing the break‑even deployment volume by 1.9–9.5× compared to conventional routers. The study also shows that the supervision level that minimizes serving cost may differ from the one that yields the earliest payback.
