LLM Routing Explained: How an LLM Router Picks the Right Model

Originally published at aiengineerinsights.com TL;DR: LLM routing sends each request to the cheapest model that can answer it acceptably, using a decision made before the expensive call — by rules, embedding similarity, a trained router (RouteLLM-style), or a calibrated decision model (Jev-style).…
