A seismic shift is coming to Siri this fall, transforming the familiar digital assistant into a powerful AI chatbot. The changes, slated for release with iOS 27, macOS 27, and their accompanying updates, represent a fundamental reimagining of how we interact with Apple devices.
The initial phase of this evolution begins with OS 26.4, expected within the next few months. While the visual interface remains unchanged, the core of Siri will be replaced with “Apple Foundation Models version 10.” This new engine, built with a staggering 1.2 trillion parameters and inspired by Google’s Gemini technology, promises a leap in intelligence and capability.
This upgraded Siri will venture beyond simple commands, gaining the ability to access and process information from the web. Long-awaited features, initially previewed earlier this year, will finally materialize – the ability to understand on-screen content, execute actions within apps, and learn from user interactions to provide truly personalized assistance.
The true revolution arrives with OS 27 and “Campos,” a Siri built upon the even more advanced “Apple Foundation Models 11.” This next-generation foundation model is reported to rival the capabilities of Gemini 3, setting the stage for a dramatically enhanced user experience.
Summoning Siri will remain familiar – a voice command or a press of the side button. However, the response will be radically different. The current listening interface will give way to a full-fledged chatbot experience, capable of answering complex questions, conducting web searches, generating text and images, and even analyzing uploaded files.
But Campos won’t stop there. It will intelligently recognize open windows and on-screen elements, allowing it to perform actions and offer relevant suggestions. Crucially, Siri will retain its unique ability to control smart home devices, manage timers, and manipulate device settings – features currently beyond the reach of third-party chatbots.
Deep integration with Apple’s core applications – Mail, Photos, Music, and more – will unlock a new level of productivity. Imagine requesting, “Find the photo I took at the park yesterday and crop it to show only my face,” and watching Siri execute the command seamlessly.
A key consideration for Apple is user privacy. Discussions are underway regarding how much conversational history Siri should retain, balancing personalization with data protection. This is particularly relevant as Apple explores the possibility of leveraging Google’s Gemini servers and powerful TPUs for cloud-based AI processing.
The initial OS 26.4 update will utilize Apple’s own Private Cloud Compute servers, powered by Apple Silicon, ensuring a degree of data security. However, the long-term strategy involves a modular design for Campos, allowing Apple to swap out underlying models as technology evolves and regional regulations demand.
This flexible architecture will enable Apple to transition away from Gemini-powered models in the future, potentially favoring its own developments or adapting to specific requirements in different parts of the world. The future of Siri is not just about intelligence; it’s about adaptability and control.
