Apple Just Paid Google $1 Billion to Think for Siri. Your Build-vs-Buy Debate Is Over.
At WWDC 2026, Apple unveiled a rebuilt Siri powered by a custom Google Gemini model reported to carry 1.2 trillion parameters, at a reported cost of roughly $1 billion a year. This article argues the deal is a template rather than a surrender: Apple rented the frontier model but kept the customer relationship, the data path, the context layer, and the interface. It sets out the four-part playbook enterprises should copy – task-level model bake-offs, gateway architecture that keeps providers swappable, owned small models for routing economics, and treating context as the proprietary asset – alongside the dependency and concentration risks of renting without an exit.
