Model Routing Is Simple. Until It Isn’t.
The article discusses the challenges of routing models in agentic systems, highlighting that cost, complexity, and latency are not simply determined by model pricing but are influenced by workload patterns, infrastructure, and governance requirements. It emphasizes that routing should be treated as an optimization problem rather than a classification task, with the goal of balancing cost, quality, and latency. The article concludes that effective routing requires considering multiple factors and avoiding oversimplifications.
