Introducing The X Subscription

I’m on the existing Cursor Ultra plan and mainly use third-party models in Cursor (Claude, GPT, and similar).

Could you confirm how third-party models are billed on The X Subscription (Premium, Super, and Ultra, including Teams)?

  1. Is there any included allowance for third-party models, with extra usage billed only after that allowance is used up?
  2. Or are third-party models excluded from the shared usage pool entirely, and billed at API list price through top-ups from the first request?

Also, if I stay on my current Ultra plan and do not switch, does my included third-party usage continue as it is today?
