Apple is Reportedly Tapping into Google Gemini to Revamp Siri

Apple’s plan to revolutionize its voice assistant Siri with advanced AI has encountered another setback, according to the latest edition of the “Power On” newsletter by Bloomberg’s Mark Gurman.

Originally slated for release during iOS 18, the revamped assistant (Siri) is now expected to debut around March 2026, with the U.S. tech giant leaning on a custom version of Google Gemini’s model to power the upgrade.

Previously, CEO Sundar Pichai said during testimony at an antitrust trial in Washington, said that Google is finalising a deal with Apple to integrate its Gemini AI into upcoming iPhones.

According to Gurman, Apple and Google have agreed to run Gemini-based AI for Siri through Apple’s private cloud compute infrastructure — though Gemini features themselves will not appear in the user-facing interface.

The delay underscores broader pressure on Apple to catch up in the aggressive AI accelerator race. While competitors like Google, Microsoft and others integrate large-language models and generative tools across their ecosystems, Apple appears to be recalibrating its timeline in the name of quality.

Apple’s own software chief Craig Federighi acknowledged at WWDC 2025 that the new Siri version “didn’t converge in the way, quality-wise, that we needed it to.”

The upgrade is expected to integrate deeply with Apple’s broader “Apple Intelligence” initiative and will reportedly launch alongside refreshed hardware, including an updated Apple TV and HomePod mini.
