Does Siri use Gemini? What Apple and Google actually confirmed

Yes. Apple's own security engineering team wrote that "Apple collaborated with Google to leverage the technologies behind its Gemini family of models to build the next generation of Apple Foundation Models that power our Apple Intelligence features." Siri AI, the rebuilt assistant Apple unveiled at WWDC 2026, runs on those models. (Sources: Apple Newsroom, Apple Security Research)

The detail that confuses people: Apple's consumer-facing WWDC 2026 press release never prints the words "Google" or "Gemini." The confirmation lives in two other places, Google Cloud CEO Thomas Kurian's April 22, 2026 keynote and Apple's Private Cloud Compute engineering post of June 8, 2026.

So Siri is not Gemini wearing an Apple badge. It is Apple Foundation Models built with Gemini technology, with the heaviest requests routed to Google Cloud hardware under Apple's own privacy architecture. (Source: Apple Security Research)

Does Siri use Gemini? The short answer

QuestionWhat the sources actually say
Is Gemini involved?Yes. Apple says it "collaborated with Google to leverage the technologies behind its Gemini family of models." (Source: Apple Security Research)
Is Siri literally Gemini?No. What ships is "the next generation of Apple Foundation Models," built using Gemini technology. (Source: Apple Security Research)
Did Apple say so in public marketing?No. The WWDC 2026 newsroom release names no model partner at all. (Source: Apple Newsroom)
Did Google say so?Yes, at Google Cloud Next '26 on April 22, 2026. (Source: 9to5Mac)
When did the deal become public?January 12, 2026. (Source: TechCrunch)
Is the deal exclusive?No. "The deal is not exclusive, per a source familiar with the matter." (Source: TechCrunch)

What Google confirmed, and when

Google was the first of the two companies to say it out loud on a stage. At the Google Cloud Next '26 opening keynote on April 22, 2026, Thomas Kurian said: "We're collaborating with Apple as their preferred cloud provider to develop the next generation of Apple Foundation Models based on Gemini technology. These models will help power future Apple Intelligence features, including a more personalized Siri coming later this year." (Source: 9to5Mac)

Two words in that sentence do most of the work. "Preferred cloud provider" is an infrastructure claim, not only a model-licensing one. "Based on Gemini technology" describes Apple's models as derived from Gemini rather than as Gemini rebadged. (Inference: AgenticWire read)

The commercial arrangement surfaced earlier, on January 12, 2026, when reporting put Apple's payment to Google at roughly $1 billion for access to its AI technology and noted the arrangement was not exclusive. (Source: TechCrunch)

Timing had already slipped before any of this. The personalized Siri overhaul was expected in spring 2026 and was pushed after accuracy problems, which is why Kurian's April phrasing was "coming later this year" rather than a date. (Source: MacRumors)

What Apple shipped at WWDC 2026

Apple's June 2026 newsroom release is the authoritative list of what users actually get:

  • A dedicated Siri app, so that "a dedicated Siri app allows users to revisit a past conversation or kick off a new one, all in one place." (Source: Apple Newsroom)
  • Personal context: Siri AI "can draw on personal context understanding to search across messages, emails, photos, and more." (Source: Apple Newsroom)
  • On-screen awareness: Siri AI "can answer questions related to the content on a user's screen." (Source: Apple Newsroom)
  • "Even more systemwide app actions," which is the concrete form the agentic framing takes. (Source: Apple Newsroom)
  • Availability: "New software features will be available as a free software update this fall," with Siri AI itself arriving "as a beta later this year for users with a supported device set to English." (Source: Apple Newsroom)
  • Regional gates: "Siri AI will not be available in China" and "will not be available initially in the EU in iOS, iPadOS, and watchOS." (Source: Apple Newsroom)

The OS train is iOS 27, iPadOS 27, macOS 27, watchOS 27, visionOS 27, and tvOS 27. If you have read a version of this story naming macOS 25, that number does not exist in Apple's release; we corrected it here. (Source: Apple Newsroom)

Where the Gemini work actually runs

This is the part most coverage skips, and it is the durable answer to whether using Siri means sending your data to Google.

Apple describes a tiered arrangement. Its Private Cloud Compute infrastructure handles cloud inference under Apple's security model, and for the hardest work that infrastructure now reaches outside Apple's own buildings: "For the most demanding tasks, including agentic tool-use and complex reasoning, we worked with Google and NVIDIA to extend our PCC infrastructure to Google Cloud systems using NVIDIA GPUs, while maintaining Apple's powerful security and privacy protections." (Source: Apple Security Research)

Apple's stated guarantee is that the boundary moves without the protections changing: "Together, these capabilities help ensure that even outside of Apple's hardware and data centers, user data will continue to be protected by the full force of PCC's extraordinary security and privacy properties." (Source: Apple Security Research)

Practical read for anyone writing a privacy review: the vendor question is no longer "Apple or Google." It is whether your organization accepts Apple's PCC attestation model as the control, given that the physical hardware for the heaviest Siri requests can sit in Google Cloud.

Operator note (first-hand): We re-verified this article against primary sources over unauthenticated HTTP on 2026-07-28 and corrected two errors from the original April 2026 draft. First, the OS claim: the earlier version named "iOS 27 and macOS 25," but Apple's WWDC 2026 newsroom release lists macOS 27, so the macOS number was wrong and is fixed. Second, sourcing: the original piece cited only T3, whose article body does not render to an unauthenticated fetch (the request returns navigation chrome only), so every claim here was re-grounded on Apple Newsroom, Apple Security Research, 9to5Mac, MacRumors, and TechCrunch instead. CNBC's January 12 write-up returned HTTP 403 and is not cited. (Sources: Apple Newsroom, Apple Security Research, T3)

What agentic Siri means for developers

Apple's own phrase for the agentic layer is "systemwide app actions," and Apple's security post names "agentic tool-use" as one of the workloads that justified extending PCC to Google Cloud. Together those two describe an assistant that calls into apps rather than reading answers aloud. (Sources: Apple Newsroom, Apple Security Research)

Decision rules for teams shipping on Apple platforms:

  • Treat the action surface, not the voice surface, as the integration point. What Siri AI can do in your app is bounded by the actions you expose to the system. (Inference: AgenticWire read)
  • Assume English-first, beta-quality behavior at launch and plan QA around the supported-device and language gates Apple published. (Source: Apple Newsroom)
  • Budget for EU and China divergence: Apple has already said Siri AI is not shipping in China and not initially in the EU on iOS, iPadOS, and watchOS. (Source: Apple Newsroom)
  • Write the data-flow section of your privacy documentation against Apple's PCC claims, since the heaviest requests can execute on Google Cloud hardware. (Source: Apple Security Research)

FAQ

Is Siri actually Gemini?

No. Apple ships Apple Foundation Models that were built by leveraging "the technologies behind" Google's Gemini family, not the Gemini assistant itself. Kurian's phrasing at Google Cloud Next '26 matches: Apple Foundation Models "based on Gemini technology." The branding, the app, and the privacy architecture stay Apple's. (Sources: 9to5Mac, Apple Security Research)

What is Siri AI powered by?

A mix. Apple Foundation Models built with Gemini technology handle the intelligence, running across on-device processing and Private Cloud Compute. For the most demanding agentic tool-use and complex reasoning, Apple extended PCC to Google Cloud systems using NVIDIA GPUs while keeping its own security guarantees. (Source: Apple Security Research)

Why is Apple using Google Gemini?

Speed to a working product. Apple's personalized Siri was expected in spring 2026 and slipped over accuracy problems, and the Google arrangement became public in January 2026 as the route to a shipping assistant. Reporting also noted the deal is not exclusive, leaving Apple room to change suppliers. (Sources: MacRumors, TechCrunch)

How much is Apple paying Google for Gemini in Siri?

Reporting around the January 12, 2026 announcement put it at approximately $1 billion for access to Google's AI technology. Neither company published contract terms, so treat the figure as reported rather than confirmed, and note that the same reporting says the arrangement is not exclusive. (Source: TechCrunch)

Is Apple putting Gemini on iPhone?

Indirectly. iPhone users get Siri AI in iOS 27, whose underlying Apple Foundation Models were built with Gemini technology, delivered as a free software update in fall 2026 with Siri AI itself in beta later in the year for supported English-language devices. There is no Gemini app branding inside Siri. (Sources: Apple Newsroom, Apple Security Research)
