Apple is reportedly preparing to overhaul Siri using Google’s most advanced AI model, as the tech giant looks to catch up in the fast-moving artificial intelligence race.
The company is set to pay Google about $1 billion a year for access to its 1.2 trillion parameter Gemini model, according to Bloomberg. The deal, which is now being finalized, would provide Apple with the core AI technology needed to power the next-generation version of its voice assistant.
Apple has been testing large language models from OpenAI, Anthropic, and Google this year. It ultimately chose Gemini after internal trials, positioning it as an interim solution while Apple works to scale its own models.
Apple to partner with Google Gemini to build a new Siri
The updated Siri is slated to debut alongside iOS 26.4 in Spring 2026. Internally known as Linwood, the new assistant will rely on Google’s Gemini to handle key features like summarization and task planning, while other Siri functions will continue running on Apple’s in-house models.
The Gemini model will run on Apple’s Private Cloud Compute servers to maintain data security. Unlike Google’s role as the default search engine in Safari, this agreement is expected to remain behind the scenes, with no public co-branding.
Apple executives Mike Rockwell and Craig Federighi are overseeing the project, codenamed Glenwood. The move marks one of Apple’s most significant outside partnerships in AI and signals a shift in strategy as the company aims to bring more modern voice capabilities to its ecosystem.
Apple still plans to replace Gemini long-term with its own cloud-based model, targeting a similar 1 trillion parameter scale. That model could be ready for consumer products as early as next year, though Google continues to advance Gemini with newer versions like Gemini 2.5 Pro.
