Apple Inc. is in early discussions about using Google Gemini to power a revamped version of the Siri voice assistant, marking a key potential step toward outsourcing more of its artificial intelligence technology.

Apple is in early talks with Google to use Gemini for a new version of Siri, part of a broader effort to catch up in AI after delays.

Alphabet stock jumped to a record high Friday afternoon after a report said Apple is exploring using Google’s Gemini to run the highly anticipated Siri voice assistant. Bloomberg reported that the iPhone maker has approached Google to look into possibly building a custom artificial-intelligence model that would be the foundation of the long-awaited AI-powered Siri.
