With a few exceptions, Apple has avoided forcing users to pay for extra access to features powered by Apple Intelligence. On Monday, it’s started to roll out a new charge aimed at Apple Creator Studio users.
Anyone who uses Apple Intelligence features in Apple’s suite of tools will find that there are usage limits as part of the monthly subscription.
