Leaked information indicates that Google's latest Gemini 2.0 models, which boast advanced reasoning capabilities, may soon be accessible on iPhones, especially on the iPhone 15 Pro and iPhone 16 series.

Currently, Apple Intelligence enables Siri to direct certain requests to ChatGPT, further improving the contextuality of its responses.

While the exact timeline for the integration of Gemini into iOS 18.4 remains uncertain, it is expected to be part of later updates for iOS 18 or possibly introduced in iOS 19, which will feature a new conversational model for Siri.

Recent backend updates in the iOS 18.4 beta have introduced options for integrating models from Google and OpenAI into Apple's Intelligence, suggesting exciting new features on the horizon.

Apple is actively preparing to enhance Siri's capabilities by integrating Google Gemini with its Apple Intelligence system, which will allow for more contextual responses.

During the WWDC 2024 event, Craig Federighi, Apple's software executive, expressed a strong interest in incorporating various AI models, including Google Gemini, into future iOS updates.
