As was just rumored, the iOS 18.1, iPadOS 18.1, and macOS Sequoia 15.1 developer betas are rolling out today, and they include the first opportunity to try out Apple Intelligence, the company’s suite of generative AI features.

Initially announced for iOS 18, Apple Intelligence is expected to launch for the public this fall. Typically, Apple also releases a public beta (the developer one requires a developer account) for new OS updates, but it hasn’t announced any specifics about that just yet.

Not all the Apple Intelligence features will be part of this beta. It will include writing tools, like the ability to rewrite, proofread, or summarize text throughout the OS in first-party and most third-party apps. It will also include new Siri improvements, such as moving seamlessly between voice and typing, the ability to follow when you stumble over your words, and maintaining context from one request to the next. (It will not, however, include ChatGPT integration; Apple says that’s coming later.)

New natural language search features, support for creating memory movies, transcription summaries, and several new Mail features will also be available.

Developers who download the beta will be able to request access to Apple Intelligence features by navigating to the Settings app, tapping Apple Intelligence & Siri, and then tapping “Join the Apple Intelligence waitlist.” The waitlist is in place because some features are demanding on Apple’s servers, and staggering access is meant to stave off any server issues when developers are first trying it out.
