Apple's newly released developer betas for iOS 18.1, iPadOS 18.1, and macOS Sequoia 15.1 contain the company's first set of AI features, including a Siri with an updated design and ability to maintain context across multiple requests, new Mail features like smart replay and email summaries, and natural language search in Photos. The features will likely not be rolled out to general users until well into 2025. They will only work on the iPhone 15 Pro or Pro Max or on iPads and Macs with Apple Silicon chips. Beta testers will need to join a waitlist for access to the features.
