Apple's new Siri AI, unveiled at WWDC 2026, runs on Google Gemini infrastructure at a cost of approximately $1 billion per year under a multi-year deal, per TechCrunch reporting [1]. Apple Senior Vice President Craig Federighi declared that "privacy in AI is non-negotiable" during the keynote, stating that "data is only used to execute your request, and outside experts can continue to verify this promise at any time" [1].

The privacy framing obscures the infrastructure reality. Apple collaborated with Google and the Gemini family of models to develop the next generation of Apple Foundation Models that power its integrated Apple Intelligence experiences [1]. The "Private Cloud Compute" architecture that Apple markets as a privacy guarantee is built on Google's compute — a dependency that TechCrunch's coverage of the Siri overhaul mentions in passing but does not interrogate.

The billion-dollar annual cost places Apple's AI ambitions in financial perspective. The company that built its brand on vertical integration and control now pays its primary competitor to run its most important consumer-facing AI product. The privacy claim holds technically — Apple controls the data pipeline — but the compute dependency is Google's.
