July 2026.

A practical reference for routing work across multiple AI providers: picking the right model per task, wiring up fallbacks, and keeping cost and quality honest.

July 2026 edition

The parts list for a working AI routing layer.

Most teams do not need one best model for every task. They need a system that can sort the work, send routine volume to inexpensive models, and reserve expensive judgment for the few moments where it changes the outcome.

Route

Send each job to the model that fits the task.

Fallback

Keep work moving when a provider slows down or fails.

Measure

Track cost, latency, and quality at each stage.
