Siri AI

Siri AI is not an incremental update to the previous Siri: it is a ground-up rebuild announced at WWDC 2026 in June 2026. The new assistant understands personal context from messages, emails, photos, and calendar; handles multi-step requests that span multiple apps; and maintains conversational memory across sessions. It includes a dedicated app on iPhone, iPad, and Mac where users can revisit past conversations and results.

On the model side, Siri AI runs on Apple's third-generation foundation models (AFM 3) for on-device tasks, and routes more demanding requests to AFM Cloud Pro, which runs on NVIDIA GPUs in Google Cloud and is refined using outputs from Google's Gemini frontier models. Apple is careful to describe the cloud model as its own, not Gemini, but the Google collaboration is significant. Privacy is handled through Private Cloud Compute: requests are processed without data being stored or accessible to Apple or anyone else.

For builders, Siri AI matters because it is now deeply integrated with App Intents, which is Apple's equivalent of function-calling for iOS apps. Apps that register their actions as App Intents become callable by Siri without the user opening the app. Apple has placed SiriKit on a deprecation path, making App Intents the mandatory way for apps to participate in the new Siri ecosystem. Siri AI is available in English first as a beta in late 2026, with more languages following. It is not available in the EU on iPhone or iPad at launch due to regulatory requirements.
