Model routing

Model routing means sending each request to one of several AI models according to rules, such as the task, the cost or the user's age.

Why it matters for schools

Routing lets a product use a low-cost model for short questions and a stronger one for hard ones, and it is how provider rules for minors can be applied automatically. It has trade-offs: prompt caches belong to one model, so switching models mid-conversation starts the cache cold, and whoever holds the router account answers for each model's terms.
