Apple has introduced a significant update in its latest iOS version, allowing users to replace the default Siri voice assistant with third-party AI models. Supported alternatives now include OpenAI's ChatGPT, Anthropic's Claude, and Google Gemini, marking a shift toward greater modularity in the Apple AI ecosystem.

Users can configure these settings within the Apple Intelligence and Siri menu or the default apps management section. The update enables users to remap physical hardware controls, such as the power button or the Action Button, to trigger a preferred third-party AI model directly, bypassing the need for Siri as an intermediary.

The new integration allows third-party assistants to access system-level context, including screen content summaries, clipboard data, and native apps like Notes and Reminders. Unlike previous implementations that required repeated privacy confirmations for cloud-based requests, this update provides a more seamless, direct interaction model.

Analysts suggest this move is a strategic response to global antitrust regulations, such as the EU Digital Markets Act, which requires tech platforms to offer users a choice of default services. By decoupling the hardware platform from its proprietary AI, Apple aims to mitigate legal risks while positioning the iPhone as a versatile hub for diverse AI services.
