What is this trend?

Model routing now sits at the center of production ML systems, letting teams send each task to the cheapest model that still meets quality and latency needs.

  • Routing is shifting from a cost hack to core system design.
  • Teams are using smaller or domain models for routine tasks.
  • Confidence thresholds and fallback paths are now production concerns.
  • Savings can be large without major quality loss.
  • Monitoring cost, latency, and accuracy together is becoming standard.
