Google’s Gemini to Power Siri’s ‘Planner’ Functions in $1B Deal

Google has secured a $1 billion annual contract to provide the core “planner” and “summariser” functions for Apple’s new Siri. This “behind-the-scenes” deal will embed Google’s 1.2 trillion parameter Gemini AI into its rival’s ecosystem.
This “interim solution” is a key part of Apple’s “Glenwood” project, the internal effort to fix Siri. The new “Linwood” Siri, launching in the spring, will be a hybrid system, using Google’s AI for complex, multi-step tasks that Apple’s 150-billion parameter models can’t handle.
Google’s “ultrapowerful” model was chosen after a “bake-off” where it beat OpenAI’s and Anthropic’s offerings. This is a major win for Google, establishing it as a go-to “AI supplier” even for competitors.
For Apple, this is a reluctant move, admitting it has fallen behind in the AI race. Top executives Craig Federighi and Mike Rockwell are tasked with overseeing the integration while simultaneously pushing Apple’s teams to build a replacement.
The entire deal is contingent on Apple’s privacy-first architecture. The Gemini model will be hosted on Apple’s Private Cloud Compute servers, not Google’s. This “walled-off” system ensures Google never gets access to Apple’s user data.
