As an iPhone user, I often get frustrated with Siri's inability to correctly respond to my questions and requests. That's especially true in the car when I'm driving. And when it fails to respond or gives me the wrong answer, that's a distraction I don't need when I'm behind the wheel.

That's why I've been looking forward to the new Siri AI, due to officially roll out in September with iOS 27. This latest generation of the voice assistant promises to be more responsive, more accurate, and less frustrating.

Does Siri AI live up to the hype? To answer that question, I recently took two iPhones with me in the car -- one with iOS 26 and the other with the iOS 27 public beta. I tasked both of them with the same questions and requests to see if and how the new Siri bested the current flavor. Here's what happened.

If you want to try out the new Siri as well, here's what you'll need.

First, you have to grab the iOS 27 public beta . Beyond being compatible with this version of the OS, your phone must also support Apple Intelligence and Siri AI . That means you need an iPhone 15 Pro, iPhone 15 Pro Max, any iPhone 16 model, or any iPhone 17 model. Since even the first public beta could be unstable, avoid installing it on your primary phone. Instead, use a spare or test iPhone. I'm using a spare iPhone 15 Pro.
