STORY: Apple will use Google's Gemini models for a revamped version of its Siri virtual assistant, which is due to debut later this year.
The multi-year deal was announced Monday, marking a major vote of confidence in Google.
Its technology already drives much of Samsung's "Galaxy AI," but the Siri deal unlocks a large market with Apple's installed base of more than two billion active devices.
Gemini models will also power other future Apple Intelligence features under the deal, the financial details of which were not disclosed.
Google parent company Alphabet has been jostling with OpenAI for the Apple deal.

The iPhone maker had in late 2024 rolled out ChatGPT on its devices.
That allowed the company's Siri voice assistant to tap into the chatbot's expertise to answer complicated questions.
Apple says there are no major changes to the ChatGPT integration at this time.
OpenAI did not respond to a request for comment by Reuters.
Parth Talsania of Equisights Research said "the deal shifts OpenAI into a more supporting role, with ChatGPT remaining positioned for complex, opt-in queries rather than the default intelligence layer."
News of the deal helped power Alphabet's market valuation above $4 trillion on Monday.
