What is tiered artificial intelligence model routing?
Definition
Tiered artificial intelligence model routing groups models by expected role, such as fast routine work, general-purpose tasks and expensive high-capability reasoning. A classifier, explicit rule or user choice assigns each request to an appropriate tier.
A tiered design should include escalation when a task fails or reveals greater complexity. Evaluation must measure complete outcomes because an inexpensive first attempt followed by several retries may cost more than choosing the stronger tier initially.

Frequently asked questions
What tasks belong in a fast-model tier?
Well-scoped edits, searches, tests and other repeatable operations belong there when evaluation shows that the model completes them reliably.
How does a workflow escalate between tiers?
It can escalate after failed verification, detected ambiguity, explicit user choice or a classifier that identifies greater reasoning or context needs.
