Apple has confirmed that Siri AI and several other features powered by its server-side models will have daily usage limits. Expanded access will eventually be available for a fee, though the company has not said when the limits will begin, what they will be, or how much additional access will cost.
The limits are disclosed in a footnote to Apple's announcement of new health features for Apple Watch Series 12 and Apple Watch Ultra 4. A new support article names Siri AI, Image Playground, AFM 3 Cloud and AFM 3 Cloud Pro models in Shortcuts, and photo editing tools such as Clean Up, Extend, and Spatial Reframing. Developer apps that use Apple Foundation Models in Private Cloud Compute are covered as well.
The caps will not necessarily be the same for every feature, with request complexity, system demand, and other factors affecting how they are set. Reaching one will make that feature unavailable for a period of time, after which access will return. Under Apple's separate usage terms, excessive, abusive, automated, fraudulent, illegal, or otherwise unreasonable use may also be restricted, throttled, or suspended.
Apple has not explained how the fee will be charged or how expanded access will differ among iCloud+ plans. For Home video summaries, the support article says the 2TB plan will cover up to one camera, the 6TB plan up to two cameras, and the 12TB plan up to five cameras.
