Siri Reimagined: Apple & Google's AI Fusion
9 Jun
Summary
- Siri's new AI is a result of Apple and Google's foundational model collaboration.
- Apple exclusively co-developed models with Google, not using Google's AI assistant.
- New Siri leverages Apple's Private Compute Cloud with Nvidia and Google servers.

At WWDC 2026, Apple finally revealed the long-promised advanced Siri, a significant overhaul resulting from intensive collaboration with Google. This new Siri utilizes foundational models co-developed with Google, distinct from the Gemini app, ensuring a purely Apple user experience.
Federighi detailed how Apple's system orchestrator interacts with new models like AFM Core (20 billion parameters) and cloud-based AFM Cloud Pro and ADM Cloud. A key innovation is the 'scarce model' approach, reducing parameter loading for improved efficiency on-device.
The cloud infrastructure is a notable evolution, extending Apple's Private Cloud Compute to third-party servers. This secure environment now operates on Nvidia and Google infrastructure, integrating Nvidia GPUs and security components from Intel and Google to support the most powerful models.
This rebuilt Siri represents a strategic fusion of Apple's vision with Google's advanced generative AI capabilities, delivering the intelligent, contextual assistant Apple customers expect.
