A routed token is any input or output token from a request covered by an AI Router routing decision, regardless of who executes the request. This means the same usage measure applies whether AI Router proxies the request or your application calls the selected model directly.
Plans include a monthly routed-token quota; usage beyond the quota is billed as overage rather than cut off, and routing is never throttled. Model costs are not part of this: with BYOK they remain on your own provider bill, the AI Router plan price covers the routing fee.
Usage comes from three sources:
Billing is based on measured usage. Where a routing decision has no usage report, we estimate its usage conservatively from your measured usage profile; the basis of that estimate is fixed in your contract. Reporting actual usage gives you the most accurate record and avoids estimates altogether.
Usage reports support more than accurate billing. Savings and opportunity reports compare routing decisions with the requests your application actually executed, so those reports are only complete when selection usage is reported back for every routing decision.
Open your team in the dashboard and go to Usage. It shows the current month's routed tokens split into measured, reported and estimated usage, your quota, and a month-by-month history.
