Apple is preparing a major upgrade for Siri, integrating advanced AI features that promise smarter and more accurate answers. According to reports, Siri in iOS 26.4 will include a web search function powered by Apple’s Foundation Models and supported by Google Gemini. The feature is expected to roll out in early 2026.
How It Will Work
The new Siri will use three core components: a planner, a search operator, and a summarizer. Apple’s Foundation Models will handle planning and search tasks, particularly for on-device personal data. When queries extend beyond the device, Google Gemini, running on Apple’s Private Cloud Compute, will provide summaries from the web.
This system will allow Siri to combine Apple’s privacy-first technology with Google’s extensive web knowledge. Unlike current integrations where Siri defaults to Google search, the new system ensures greater contextual awareness and more meaningful summaries for users.
Balancing Privacy and Power
Apple’s approach emphasizes security. All queries processed through Private Cloud Compute will remain private, with no data stored or used for training. These servers run on renewable energy, aligning with Apple’s environmental goals.
This strategy mirrors Apple’s long-standing approach: not rushing to be first, but aiming to deliver the most secure and reliable experience. Tim Cook has emphasized that Apple’s deliberate pace ensures customers receive useful features rather than experimental ones.
Looking Ahead
The Siri upgrade marks Apple’s most ambitious AI move yet. While competitors like Google and OpenAI race to release chatbots, Apple is positioning Siri as a trusted, privacy-focused assistant.
If successful, the new Siri could transform how iPhone users interact with their devices, combining speed, security, and smarter answers. The real test, however, will come in early 2026, when the feature debuts with iOS 26.4
