At the 2026 Apple Worldwide Developers Conference (WWDC 2026), Apple confirmed that the new generation of Siri AI will arrive on the iPhone alongside iOS 27. This version is seen as a significant update in Apple's smart assistant field, coming two years later than initially promised, and marks a new starting point for Apple in the direction of 'personalized AI assistants.' Siri AI is deeply integrated into iOS 27, adopting a new AI architecture and collaborating with Google to introduce the Gemini large model. It features stronger contextual understanding capabilities, can perform tasks across applications, and supports an independent Siri app for managing historical conversations. In terms of performance, iOS 27 optimizes speeds for app launches, photo loading, and more, while also introducing a new system-wide transparency adjustment feature.
