From Direct Classification to Agentic Routing: When to Use Local Models vs Azure AI - DEV Community

This page discusses classification system design in enterprise environments, covering email triage, ticket routing, and similar tasks. While these problems appear straightforward, they require considering latency, cost, governance, data sensitivity, and operational fit beyond model accuracy. The architectural design matters more than the model itself. Rather than asking "which model is better," the key question is "where each model fits in the architecture." The post examines when local/department-level models make sense versus when Azure AI or cloud solutions are preferable, and explains how an agentic routing layer fundamentally changes the overall design approach.
