Apple has announced a ground-up rebuild of Siri, powered by Google's Gemini model running on Apple's Private Cloud Compute infrastructure. The announcement marks the most significant change to Siri since its introduction in 2011.
Private Cloud Compute
The new Siri processes complex queries in the cloud while maintaining Apple's privacy guarantees. Apple's Private Cloud Compute architecture ensures that queries are processed on Apple-controlled servers using hardware attestation — meaning not even Apple employees can access user data.
What the new Siri can do
The rebuilt Siri handles multi-step tasks on-device for the first time — combining actions across multiple apps without sending data to external servers. For more complex queries requiring frontier intelligence, it routes to Gemini via Private Cloud Compute.
Why Google, not OpenAI?
Apple had previously partnered with OpenAI for ChatGPT integration in Apple Intelligence 1.0. The shift to Gemini is reported to reflect both performance advantages and a deeper commercial relationship between Apple and Google, which already pays Apple billions annually for default search placement.
The new Siri is expected to roll out with iOS 20 later this year.
