Apple integrates ChatGPT deeply into iOS 18

Apple Intelligence is the core of generative AI features in iOS 18, but Apple will also let users sign in with their OpenAI account and use ChatGPT models as well.

Once connected, users can select ChatGPT as their model to use inside Siri and as part of the new intelligent writing tools and other features across iOS 18, iPadOS 18 and macOS Sequoia.

The ChatGPT integration extends the free Apple Intelligence functionality built into the OS. For example, if you ask Siri a question that it can’t answer, it could hand off to ChatGPT instead to respond to the query.

Users can take advantage of the usual free quotas for ChatGPT usage, or connect their paid subscriptions to use their ChatGPT Plus benefits instead.

Apple indicated that it is working on partnerships with other AI model makers to give users more options in the future. So, although OpenAI’s ChatGPT will be the only option to start, you can expect Google Gemini and other models to be offered in the future.
