Google’s $1B ‘Walled-Off’ Victory: Gemini to Power Siri

Google has scored a $1 billion-a-year victory, but it comes with a “walled-off” catch. Apple will use Google’s 1.2 trillion parameter Gemini AI to power its new Siri, but the model will be hosted on Apple’s Private Cloud Compute servers.
This “interim solution” is the cornerstone of Apple’s “Glenwood” project to fix Siri. Google’s “ultrapowerful” AI won a “bake-off” against OpenAI and Anthropic, and it will now handle all complex “summariser” and “planner” functions for the new “Linwood” assistant.
This hybrid system will use Apple’s 150-billion parameter models for simple tasks and Google’s AI for complex ones. It’s a reluctant admission of Apple’s AI lag, overseen by executives Craig Federighi and Mike Rockwell.
The “walled-off” architecture is non-negotiable. It ensures Google gets its $1B fee but no access to Apple’s user data, a critical component of the deal.
While Apple pushes its teams to build a 1T+ replacement, this “temporary” fix could last for years, a testament to Google’s AI lead.
