About this tag
The ai routing tag covers discussions of how organizations direct AI prompts and workloads between different models. Recent coverage focuses on using expensive frontier models to plan complex tasks and establish guardrails, then assigning bounded execution work to cheaper systems to control token costs. It also follows Microsoft’s production use of its own MAI models for prompts from Microsoft 365 Copilot in Excel and Outlook, alongside continued use of external providers. These articles examine model selection as an architectural and operational decision, including replaceable AI infrastructure, cost management, workflow design, and the practical trade-offs involved in routing enterprise workloads.

The move is not a...
