The short answer: upgrade to an Apple Intelligence device
Siri AI is Apple’s new personalised assistant that runs on Apple Intelligence–ready hardware, combining a dedicated Siri app and system features across iPhone, iPad, Mac, Apple Watch and Vision Pro to deliver conversational, Claude‑like answers, synced chats and more powerful controls when you update to the latest operating systems.
For most people, the best way to get full Siri AI device support is to move onto an Apple Intelligence phone such as an iPhone 16‑series or later, paired with at least one M‑series Mac or iPad. Siri AI launches alongside iOS 27, iPadOS 27, macOS Golden Gate and watchOS 27, but “not all devices compatible with the new software will support Siri AI,” because they must also support Apple Intelligence. That is why this guide focuses on hardware, not only software versions. If you want the new Siri app, synced conversations and future Apple AI features rollout, prioritise an eligible iPhone first, then match your iPad, Mac and Apple Watch around it.
iPhone and iPad: who gets Siri AI first
On mobile, Siri AI support starts with Apple Intelligence‑capable iPhones. Supported phones include iPhone 15 Pro and Pro Max, the full iPhone 16 family (16, 16 Plus, 16e, 16 Pro, 16 Pro Max) and the newer iPhone 17 line (17, 17e, 17 Pro, 17 Pro Max) plus iPhone Air. If you are holding anything older, you will not get Siri AI even if you install iOS 27, so plan an upgrade rather than waiting for a later update to change that. For tablets, Siri AI works on iPad Pro and iPad Air models with an M1 chip or later, and on the A17 Pro‑based iPad mini. That means any A‑series iPad Pro before Apple silicon, older Air models and earlier minis are out of the running, regardless of their iPadOS 27 compatibility.
If you want the richest experience on iPhone, target newer flagships. Some Siri AI features, such as changing the assistant’s pace and expressivity, need specific devices: “iPhone 17 Pro, iPhone 17 Pro Max, iPhone Air” according to Apple. On iPad, the same advanced options require M4‑based models with at least 12GB of unified memory, so earlier M1 or M2 iPads run Siri AI but miss these refinements. Once you are on compatible hardware, you also gain the new Siri app, where you can type or speak queries, view and rename conversations, and sync them across devices via iCloud for a more app‑like AI experience.
Mac, Apple Watch and Vision Pro: desktop and wearable support
On desktop, Siri AI lands on “all Mac models with Apple silicon (M1 chip and later, and A18 Pro chip)” once they are running macOS Golden Gate. Any Intel‑based Mac is excluded, even if it receives the new OS. For advanced Siri AI controls like voice pace and expressivity, you need Mac models with M3 or later and at least 12GB of unified memory. If you rely heavily on Siri for work, that memory requirement alone can justify picking a newer MacBook or desktop. Vision Pro support is much simpler: all Vision Pro models run Siri AI, with Apple’s higher‑end M5‑based version required for the enhanced pacing and expressivity features.
Wearables are more limited. Apple Watch Series 9 and later, Apple Watch Ultra 2 and later, and Apple Watch SE 3 will support Siri AI once updated to watchOS 27. However, an Apple Watch “needs to be paired with an Apple Intelligence supported iPhone to run Siri AI,” so pairing these watches with older phones will not unlock the new assistant. In practice, that means treating your iPhone as the anchor of your Siri AI ecosystem: update the phone first, then your Watch. Vision Pro users who are early adopters will also see Siri AI appear as soon as they update, without needing to replace the headset hardware.
Rollout timing, OS updates and the new Siri app experience
Siri AI arrives with iOS 27, iPadOS 27, macOS Golden Gate and watchOS 27, “likely next month alongside the new iPhones,” but feature rollout is staggered. Two checks matter before you update: first, confirm your device supports Apple Intelligence; second, understand that not all Siri AI features appear on day one or on every supported device. For example, the ability to customise Siri’s voice pace and expressivity is reserved for iPhone 17 Pro, 17 Pro Max, iPhone Air, M4 iPads with at least 12GB RAM, M3‑and‑newer Macs with at least 12GB RAM, and Apple Vision Pro (M5). Updating an older compatible model will still bring the new assistant, but not every refinement.
Once you are on the right OS and hardware, Siri AI appears both as a system assistant and as a dedicated app. The Siri app works like a text‑first AI chat, similar to other conversational tools: you can type or speak, and each query is stored as a conversation that syncs across iPhone, iPad and Mac via iCloud. You can change between list or grid views, rename and pin important threads, set the app to open straight into a new conversation, and even auto‑delete older chats after 30 days or one year. These tools make Siri AI feel more like a real productivity app than a transient voice assistant, so the upgrade makes sense if you plan to use AI often.
Buy if / Skip if
- Buy the iPhone 17 Pro or Pro Max if you want every Siri AI feature, including the new pace and expressivity controls from day one.
- Skip the iPhone 17 Pro or Pro Max if your main phone use is simple calls and messages and you rarely rely on Siri or AI tools.
- Buy the iPhone 16 or 16 Pro series if you want full Siri AI device support without paying for the very newest hardware generation.
- Skip the iPhone 16 or 16 Pro series if you already own an iPhone 17‑family device or iPhone Air, as the upgrade in Siri AI features will be minimal.
- Buy the iPad Pro or iPad Air with an M‑series chip if you want the new Siri app and Apple Intelligence features on a large screen for work or study.
- Skip the M1 iPad Pro or Air if you care about advanced Siri voice tuning, because this needs newer M4‑based models with at least 12GB memory.
- Buy the latest Apple silicon Mac (M3 or later) if you want Siri AI plus the enhanced voice customisation options on macOS Golden Gate.
- Skip older Intel‑based Macs if your main reason to upgrade macOS is Siri AI, because they do not support the new assistant at all.
- Buy the Apple Watch Series 9 or later if you already use an Apple Intelligence iPhone and want Siri AI on your wrist for quick interactions.
- Skip the Apple Watch upgrade if your current iPhone cannot run Apple Intelligence, since the Watch needs a supported iPhone to use Siri AI.
