During the Worldwide Developers Conference (WWDC) 2026, Apple introduced a substantial upgrade to Siri, marking the most significant change since its 2011 launch. Dubbed Siri AI, the assistant features a dedicated app and a redesigned interface, enhancing its conversational abilities and context awareness. This new version allows users to receive responses through the iPhone's Dynamic Island, providing richer information such as reminders and web search results. The upgrade leverages a new generation of Apple's Foundation Models, developed in collaboration with Google, to improve Siri's contextual understanding and relevance in responses. Apple highlighted its commitment to user privacy, asserting that data processed through Siri AI is not stored by the company. This transformation is crucial for Apple's AI ambitions, especially as it faces competition from advanced systems developed by Google and Microsoft. In addition to Siri, Apple announced iOS 27, compatible with devices as far back as iPhone 11, and a new macOS version named Golden Gate, alongside expanded parental controls and performance enhancements across its platforms.
