But apparently the tech giant isn’t wresting its hardware out of competitors’ hands,
, who routinely leaks upcoming iOS and MacOS code. Instead, according to the post, Apple’s AI will feature deep integration with third-party models, including OpenAI’s ChatGPT and Anthropic’s Claude, with an option to entirely replace Siri with certain GPT models as the on-device agent of choice.
Representatives for Apple, OpenAI and Anthropic didn’t immediately respond to requests for comment.
The latest private frameworks leaked for iOS 27 and MacOS Golden Gate supposedly include Claude models as part of the model delegation feature, where Siri AI users can ask Apple’s model to delegate tasks to another agent.
, Siri passes along a request to Claude to create a reminder in the Reminders app. Claude essentially functions as the on-device AI in this video, with Siri working as an intermediary. And if a given request requires access to proprietary Apple system information, it is handled by Siri AI instead.
Also on display was an even more robust app extension that completely replaces Apple’s own Siri AI model with a different LLM.

Although Apple isn’t opening its doors to third-party AI companies out of the goodness of its own heart, this is big news for OpenAI and Anthropic, the developers of ChatGPT and Claude.
The two companies are racing to develop more advanced models — and
looming in the near future, it’s likely that OpenAI and Anthropic will continue to try to tap into
