Improvements to a number of Apple services - including a more personalised version of its virtual assistant, Siri - are to be powered with AI provided by Google.
The tech giants have announced a "multi-year collaboration" which will see the iPhone-maker base some of its key tech on Google's Gemini AI models.
In a joint statement, the two firms said the partnership would unlock "innovative new experiences" for Apple users.
However, experts say it demonstrates how Apple's cautious approach to building and rolling out its own AI tools has left it reliant on other companies.
