With the latest updates, Apple Intelligence will be turned on by default when the latest software update is installed, expanding the number of users who are exposed to the software. Apple Intelligence is marketed as being able to rewrite text, generate images, and summarize long emails and message threads.
"For users new or upgrading to iOS 18.3, Apple Intelligence will be enabled automatically during iPhone onboarding," Apple said in the developer release notes for the update.
Users will have to navigate to the Apple Intelligence page in the Settings app to turn it off, according to Apple.
