Since the launch of Apple Intelligence, Apple has expressed intentions to collaborate with multiple AI partners, including Google.

Apple's agreement with OpenAI ensures that user data is not retained, and a similar privacy protection is expected with Google.

Currently, Apple Intelligence enables Siri to direct user requests to ChatGPT for enhanced contextual responses.

Discussions about integrating Google Gemini reportedly began in March 2024, but it has taken nearly a year for the implementation to come to fruition.

Apple is set to integrate Google Gemini into its Apple Intelligence platform, as indicated by code found in the latest iOS 18.4 beta.

The integration process will involve user requests being initially processed by Siri, which will then pass them to the AI service with user consent if necessary.

Google's latest Gemini 2.0 models, featuring advanced reasoning capabilities, may soon be available on iPhones, particularly for the iPhone 15 Pro and iPhone 16 series.

The integration of Google Gemini is expected to be a free addition to Apple Intelligence, with any potential charges for certain features not anticipated before 2027.

Although the presence of code in the iOS 18.4 beta suggests imminent integration, it does not guarantee an official launch.

During the WWDC24 event, Apple's software executive Craig Federighi expressed interest in integrating various AI models, including Google Gemini, into future iOS updates.

The newly discovered code suggests a backend update that references both Google and OpenAI, indicating a potential shift from the existing ChatGPT integration.

While the exact timeline for the Gemini integration within iOS 18.4 remains uncertain, it is likely to occur in later updates of iOS 18 or possibly in iOS 19, which will introduce a new conversational Siri model.
