The new Apple Intelligence features and the updated Siri AI have been designed to work across iPhone, iPad, Mac, Apple Watch, and Vision Pro. There’s a dedicated Siri AI app, with a ChatGPT-esque chatbot experience, new AI-powered camera and photo editing features, and the beginnings of an agentic experience that will let Siri AI interact with other apps and software on your iPhone, iPad or Mac.

Whatever device you access the new AI from, Apple says the processing will be roughly the same: Queries will be handled on-device where possible and in its secure Private Cloud Compute system when not. Apple says your data won’t be stored, will only be used to execute your request, and won’t be accessible to Apple or anyone else. Conversation logs in the new Siri AI app will be kept, but only on-device and in your end-to-end encrypted iCloud account.

This architecture itself isn’t new — Private Cloud Compute was announced alongside the initial Apple Intelligence launch in 2024. But two years on, two things have changed. First, Apple is undeniably behind almost every competitor on AI, even after yesterday’s announcements. That makes its privacy pitch more important than ever as a way to differentiate itself from the competition. It’s the second change that makes that trickier: In part because it’s so behind, Apple is now working with Google and Nvidia to run its AI operation.

Instead of being designed entirely in-house, Apple’s new cloud AI models are based on Google Gemini. Meanwhile Private Cloud Compute has expanded beyond Apple’s own data centers, running on Google Cloud systems using Nvidia GPUs, Intel CPUs, and Google Titan chips.
