Most requests are easy. Send them to a cheap model, keep a top model for the hard ones, and pay a fraction of the bill.

How to split the work

Most apps send many simple requests and a few hard ones. Easy: sorting a message, pulling fields out of a document, answering from a FAQ, writing a short reply. Hard: multi-step reasoning, code changes, long analysis, anything where a mistake is costly.

Three ways to route requests

  1. By task: your app already knows what it is doing (a support ticket or a contract review) and picks the model.
  2. With a sorter: a cheap model reads each request first and labels it easy or hard.
  3. By escalation: the everyday model answers first; when it is unsure or a check fails, the request goes to the top model.

Before switching, test the everyday model on a sample of your real requests: the overall index measures general ability, not your task.
