Apple’s ‘Linwood’ Siri: A $1B Fix Using Google’s Gemini

Apple’s “Linwood” Siri, the company’s next-generation assistant, is a $1 billion-a-year “interim solution” that relies on Google’s Gemini AI. The “ultrapowerful” 1.2 trillion parameter model will be the “behind-the-scenes” engine for Siri’s most complex tasks.
This deal is part of Apple’s “Glenwood” project, the internal effort to fix Siri. Google’s AI won a “bake-off” against OpenAI and Anthropic, and it will now handle all “summariser” and “planner” functions, enabling multi-step commands.
The new Siri will be a hybrid. Apple’s 150-billion parameter models will manage simple requests, while Google’s AI will tackle the heavy lifting. This is a reluctant admission of Apple’s AI lag.
The project is overseen by executives Craig Federighi and Mike Rockwell, who are tasked with delivering a competitive assistant, even with a rival’s tech.
The entire deal is contingent on Apple’s “walled-off” privacy system. The Gemini model will run on Apple’s Private Cloud Compute servers, not Google’s, ensuring user data remains secure.
