The next update to Apple’s operating systems could allow users to choose their preferred AI model for running Apple Intelligence. According to Bloomberg’s Mark Gurman, Apple is planning to allow third-party chatbots to power its AI features system-wide in iOS 27, iPadOS 27, and macOS 27, all expected for this fall. In addition to running Siri, compatible third-party AI models, called “Extensions,” will also now be able to run other Apple Intelligence features like Writing Tools and Image Playground.

According to Gurman, Apple will also allow users to choose different Siri voices for different AI models — Siri responses from one of Apple’s AI models could have one voice, while an instance of Siri running on ChatGPT could use another voice.

Users will be able to “choose from AI model providers that opt in by adding support through their App Store apps.” Once a compatible AI app is installed, users will be able to set it as their preferred AI through the Settings app. Gurman says Apple is already internally testing integrations with Google and Anthropic’s AI models. Google’s models are also the backbone of Apple’s upcoming Siri revamp, but so far ChatGPT has been the only third-party AI model integrated into Apple Intelligence, which may not be the case much longer.
