Siri has long been the weakest link among major virtual assistants, and Apple’s push for Apple Intelligence over the past two years did little to change that. Two major iOS versions came and went without the supercharged Siri Apple had promised at WWDC 2024. That changes this fall.
At WWDC 2026, Apple announced a genuinely improved version of Siri, now called Siri AI, and early hands-on time with the assistant suggests it actually lives up to the hype. It handles complex questions well, can chain commands together, and pulls context from your personal data in a way the old Siri never could.
The catch? Not every iPhone will get it, and not every compatible iPhone will get the same version.
Only devices that support Apple Intelligence will receive Siri AI when iOS 27 launches this fall. That means you need one of the following:
- iPhone 15 Pro or later
- iPad models powered by Apple silicon
- Mac models powered by Apple silicon
- The 2024 iPad mini, which uses the same chip as the iPhone 15 Pro
The easiest way to check if your iPhone qualifies is to open the Settings app and scroll down. If you see an “Apple Intelligence and Siri” section, your device is compatible. iPhones going back to the iPhone 11 will run iOS 27, but Apple Intelligence support is a separate requirement, and that cuts off anything older than the iPhone 15 Pro.
Apple also says Siri AI will launch as a beta, which means users will likely need to opt in manually rather than getting it automatically on day one. That mirrors the opt-in process iPhone owners encountered with earlier Apple Intelligence features.
At the core of the upgrade is a set of newer Apple Foundation Models running on-device. That approach should improve response speed and keep your data private. When a request is too complex for the on-device model, it gets sent to Apple’s Private Cloud Compute, which Apple says keeps that data inaccessible to anyone else, including Apple itself.
The assistant can now draw on personal context, meaning it can reference information from your notes, messages, emails, and photos when answering questions. That kind of personal awareness is what Google Assistant and Amazon Alexa have offered for years, and it’s something Siri users have been waiting a long time to see.
Owners of the iPhone 17 Pro, iPhone 17 Pro Max, and the iPhone Air will get a step up from there. Those models run a more powerful on-device AI model, which brings:
- More expressive Siri voices
- Better speech recognition
- More accurate dictation
The upcoming iPhone 18 Pro and the rumored iPhone Fold are expected to carry those same powerful on-device models. Whether the standard iPhone 18 will too is still unclear. Analyst Ming-Chi Kuo has reported that Apple is considering bumping non-Pro iPhone memory to 9GB, but Apple’s most capable on-device AI models require at least 12GB of RAM. That gap may mean the base iPhone 18 gets a lighter version of Siri AI, similar to how the iPhone 15 Pro and iPhone 16 differ today.
That memory divide is worth paying attention to. As AI assistants become more capable, the hardware running them matters more. Apple has quietly created a two-tier system where Pro models get meaningfully better AI experiences, and that gap looks set to widen with each generation.
To be fair, Apple Intelligence has been underwhelming since its debut. Many of the features felt rushed and added little real value. Siri AI feels different, at least based on what’s been tested so far in developer beta builds. It’s fast, it’s accurate, and it actually does what you ask. Whether that holds up in the stable release this fall remains to be seen, but for the first time in a while, the expectations feel reasonable.
