Apple Has Built a Framework for Third-Party AI Models in Siri [Report]

Apple has built a framework that would let users choose between Siri, ChatGPT, and other third-party AI assistants in iOS 27, according to a new report from Mark Gurman.



In a newsletter to subscribers, Gurman says Apple has developed a system known internally as Extensions that would allow third-party AI assistants to integrate directly with Siri and Apple Intelligence. Rather than relying solely on Apple's own models, the framework is designed to support outside AI services across the operating system, giving compatible assistants a standardized way to plug in without Apple having to build a separate integration for each one.


Underlying support for the feature is reportedly already present in the first developer beta of iOS 27. Apple has built a settings panel for controlling the functionality, though it remains toggled off on the backend, along with a dedicated App Store section intended to surface compatible AI applications. An AI chatbot picker is said to be functional in internal Apple builds, allowing users to switch between Siri and ChatGPT while laying the groundwork for additional providers in the future.

According to the report, Apple has also held discussions with OpenAI, Anthropic, and Google about the specific software entitlements developers would need to apply for to integrate their services with Siri and Apple Intelligence. The conversations suggest Apple is actively preparing the infrastructure required to support multiple AI providers within its ecosystem.

Although Apple devoted a significant portion of its WWDC keynote to artificial intelligence, it did not publicly discuss the Extensions framework, which Gurman says has been active internally for months. He offers several possible reasons for the silence: demonstrating strong interoperability for outside AI services could undercut Apple's ongoing argument against the European Union; the feature could have overshadowed Apple's own Siri overhaul and new Siri app; publicly ending ChatGPT's exclusive status at its developer conference risked litigation from OpenAI; and it would have further complicated messaging while Apple was already explaining its integration of Google's models and the rebuilt Siri. Apple has not indicated when it plans to make the framework available to developers or users.
