What changed
Cursor Router classifies each request by task type and complexity, sending harder work to frontier models and the rest to cheaper ones. After choosing Auto you pick Intelligence, Balance or Cost; Balance and Intelligence requests are billed at the rate of whichever model the router picks. Admins can enable the router per team or group, restrict modes, set a default and allow or block underlying models. It is on by default for Teams and must be enabled on Enterprise, and works on desktop, web, iOS, the CLI and the SDK.
Who it affects
Anyone using Auto mode, and admins who manage model spend.
What to do
Teams admins should check the default mode, because the router is on automatically and Balance and Intelligence bill at the routed model’s rate. Cost-conscious users should pick Cost.
