Apple demonstrated a lot of AI features in iOS 18, but made it clear that Apple Intelligence will not be available until March 2025, when iOS 18.4 is released. However, the latest Power On report from Bloomberg journalist Mark Gurman suggests that some AI-powered Siri features will be available earlier.
According to the journalist, some AI features of Siri may appear in iOS 18.3, but it is not yet known which ones.
By the way, the roadmap so far outlines the debut of Apple Intelligence in iOS 18.1 in October, followed by iOS 18.2 in December and iOS 18.3 in January. However, the most interesting AI features that Apple showed on stage during WWDC 2024 and the iPhone 16 presentation will be available in the first quarter of 2025 with the release of iOS 18.4.
