This tutorial demonstrates how to build a cost-aware routing layer for LLM agents using Python. The approach involves defining different model tiers with associated costs and capabilities. A task router then scores the difficulty of a given task and selects the most cost-effective model tier capable of handling it. The system includes features like cascading routing, where simpler models are tried first and escalated to more powerful ones if confidence is low, along with cost attribution and budget guardrails to manage expenses.
