Apple Intelligence AI Features to Require 4GB Storage on iPhones

Users of iPhone 16 and other compatible models will need to manage storage for new AI capabilities starting with iOS 18.1.

Apple Intelligence features will roll out with iOS 18.1, requiring 4GB of storage on compatible iPhones.
Supported devices include iPhone 15 Pro, iPhone 15 Pro Max, all iPhone 16 models, and iPads and Macs with M1 chips or later.
The initial 4GB storage requirement is in addition to the space needed for the iOS 18.1 update itself.
Future updates will increase storage needs as more AI features are added, potentially doubling the requirement.
Users with 128GB iPhone models may need to free up space, while those with higher storage variants are less likely to be affected.
