Apple and Google are drawing closer in a partnership that could reshape how iPhones handle advanced artificial intelligence. In a moment that turned heads across the tech industry, Apple received notable attention during Google Cloud Next 2026, signaling just how significant Apple has become as a Google Cloud customer and how important Google’s Gemini AI models are to Apple’s next wave of AI features.
At the event, Google highlighted Apple’s decision to use Gemini technology as a key component behind the new Siri experience. That kind of mention isn’t just casual name-dropping. It’s a strong public reminder that Google has landed one of the world’s most high-profile tech companies as a major AI customer—while also positioning Gemini as a top-tier choice for large-scale consumer products.
Behind the scenes, the partnership is reportedly backed by an enormous financial agreement. Apple is said to have signed a deal with Google that could be worth up to $5 billion early on, with the potential to grow over time. The reported structure includes Apple paying roughly $1 billion per year, described as a licensing-style fee, in exchange for deploying a custom Gemini AI model.
A key detail is the scale of the model Apple is believed to be using: a custom Gemini system with around 1.2 trillion parameters. Rather than running entirely in the open cloud, the model would be deployed on Apple’s private servers, allowing Apple to keep tighter control over how AI requests are handled.
Privacy, as expected, remains central to Apple’s messaging. The arrangement reportedly relies on encrypted and stateless data processing, which is designed to help answer complex AI queries without storing personal user information in a way that could be traced back to individuals. Apple’s position is that this setup will not weaken its existing privacy protections, even though Google’s technology is involved behind the scenes.
The partnership is also expected to play a major role in Siri’s next evolution. Apple’s revamped Siri, planned to arrive with iOS 27, is reported to run using Google’s TPU hardware and cloud infrastructure—while still operating under Apple’s ownership and control. In other words, Google supplies the AI horsepower and infrastructure, while Apple keeps the steering wheel, particularly around product experience and privacy safeguards.
On the model side, Siri’s upgraded intelligence is expected to leverage a more advanced Gemini-based system described internally as Apple Foundation Models version 11. The expectation is that this model will be competitive with Gemini 3, suggesting Apple is aiming for a meaningful leap in performance rather than a minor refresh.
Given the size of the deal and Apple’s global influence, Google’s decision to spotlight the partnership at Cloud Next 2026 makes sense. For Google, it’s a marquee customer win that reinforces the power of Gemini and the value of Google Cloud’s AI stack. For Apple, it’s a way to accelerate Siri’s AI upgrade using a proven large-scale model while keeping its privacy narrative intact.
If the rollout goes as described, iOS 27 could mark a turning point for Siri—one powered by a major Apple-Google collaboration that blends Google’s AI infrastructure with Apple’s tightly controlled ecosystem.
