According to 9to5Mac, Apple has finalized its strategy for the new Siri update coming with iOS 26.4 in spring 2025, with Google Gemini models secretly powering much of the experience behind the scenes. The custom Gemini model will run on Apple’s Private Cloud Compute servers to fulfill user requests, enabling Siri to answer personal questions by hunting through device data and generating responses on-the-fly. The new Siri architecture will feature three components—query planner, knowledge search system, and summarizer—with Google Gemini providing planner and summarizer capabilities while maintaining privacy through Apple’s server infrastructure. Apple is not expected to promote this partnership publicly, instead marketing the technology as Apple’s own running on Apple servers, with the deal helping fill crucial technology gaps where Apple’s own LLM systems currently fall short.

The Unspoken Strategic Concession
This arrangement represents one of the most significant strategic concessions Apple has made in recent memory. While Apple has historically partnered with Google for search revenue sharing, embedding Google’s core AI technology into Siri represents a fundamental dependency that Apple has avoided for years. The company that built its reputation on vertical integration and controlling the entire stack is now outsourcing what may become the most critical technology of the next decade. What’s particularly telling is the secrecy—Apple understands the brand damage of admitting its AI capabilities lag behind competitors, so they’re opting for technological white-labeling while maintaining the Apple-first marketing narrative.
The Privacy Paradox
Apple’s promise that “user privacy will be preserved by running the Google models on Apple’s server infrastructure” deserves careful scrutiny. While Apple’s Private Cloud Compute servers provide a technical barrier, the fundamental reality is that Google’s AI models will be processing Apple user data, even if through an intermediary layer. The distinction between “Google’s servers” and “Google’s models on Apple’s servers” is technically meaningful but practically subtle for end users. More importantly, this arrangement creates a long-term dependency where Apple’s privacy promises become contingent on Google’s continued responsible handling of the underlying model technology and training data.
The Technical Debt Time Bomb
By relying on Google Gemini to fill capability gaps, Apple risks accumulating significant technical debt in its AI strategy. The company’s approach suggests they’re treating this as a temporary bridge while developing their own capabilities, but AI model development isn’t something you can quickly catch up on. The danger is that Apple becomes permanently dependent on Google for core AI competencies while their own teams focus on integration rather than fundamental model development. This creates a vendor lock-in scenario where Apple’s AI roadmap becomes partially dictated by Google’s development priorities and licensing terms.
Shifting Competitive Dynamics
This partnership fundamentally alters the competitive landscape in the AI assistant space. Rather than a three-way battle between Apple, Google, and Amazon, we’re now seeing the emergence of a more complex ecosystem where former competitors become technology providers. The comparison to Samsung’s Galaxy AI features being wrappers around Google Gemini is apt, but Apple has far more at stake in maintaining its differentiation. The risk for Apple is that they become just another customer of Google’s AI empire rather than a true competitor, potentially ceding long-term strategic advantage in what may become the defining technology platform of the next decade.
The Consumer Trust Challenge
Apple’s decision to keep this partnership secret raises questions about transparency and consumer trust. While most users won’t care about implementation details, the deliberate obfuscation of where core technology originates could backfire if discovered. Apple has built its brand on authenticity and control—”Designed by Apple in California” carries weight because consumers believe Apple creates the technology they’re using. When the reality is that significant portions are licensed from their biggest competitor, that brand promise begins to erode. The marketing challenge will be maintaining the illusion of complete Apple control while relying on Google’s AI engine under the hood.
The Integration Trap
Looking forward, this partnership creates an integration challenge that could hamper Apple’s ability to innovate independently. Every Siri feature built on top of Google’s models creates dependencies that make future migration to Apple’s own technology more difficult. The query planner and summarizer capabilities mentioned aren’t trivial components—they’re core to how Siri understands and processes requests. By building their architecture around Google’s technology, Apple may find themselves locked into Google’s development timeline and capability roadmap, potentially limiting their ability to create truly differentiated AI experiences that leverage their unique hardware and ecosystem advantages.
