If you're not happy with Apple Intelligence, Apple will allow you to use ChatGPT privately for free instead via Siri and system wide like with Writing Tools.
ChatGPT is coming to iOS 18
Apple's partnership with OpenAI has been detailed during WWDC 2024. ChatGPT will be available as a free and private option in iOS 18, iPadOS 18, and macOS Sequoia later in 2024.
Even though Apple has introduced Apple Intelligence and server-side LLMs powered by Apple Silicon, the company has given users an option to utilize ChatGPT instead. For example, the option may appear when asking Siri a question or when writing with Writing Tools.
The partnership allows users to access ChatGPT's 4o model for free, at least to some extent. Users can also connect their premium account for more specific options, rather than relying on a GPT app.
Those using the free ChatGPT integration can do so without privacy concerns. Requests aren't logged and user data isn't saved.
Apple also hinted that other models may be available at a later date, like Google Gemini.
iOS 18, iPadOS 18, and macOS Sequoia are available to developer beta testers on Monday. The ChatGPT integration won't be available until sometime after the public release of the operating systems in the fall, so don't expect early access to the feature.
