The days of ChatGPT being the exclusive LLM provider for Siri may be coming to an end. According to a new report by Bloomberg’s Mark Gurman, Apple is planning to open Siri to third-party AI assistants in order to boost the iPhone as an AI platform.
Apple could roll out the new move with the upcoming iOS 27 update in September and reveal it at the WWDC 2026 conference in June.
What is Apple planning?
Apple had struck a partnership with OpenAI in 2024 to have ChatGPT handle more complex queries that users submit to Siri. However, the Cupertino-based tech giant will now allow other rival AI services like Google, Anthropic and Grok to do the same task.
The tech giant is said to be developing new tools that would allow AI chatbot apps installed from the App Store to integrate with Siri. The chatbots could also work with an upcoming Siri app and other Apple Intelligence features.
In practice, this would mean that if users have AI apps like Google’s Gemini, Anthropic’s Claude, and xAI’s Grok installed on their iPhones, they can send queries to those assistants via Siri.
Notably, this move is said to be separate from Apple’s use of Gemini to rebuild Siri as an AI assistant.
How will Apple’s Extension system work?
One big caveat here could be that the ‘Extension system’ would work only if the AI services allow their apps to do so.
The company will reportedly allow users to choose which services they want to work in Siri via the menu in iOS 27, iPadOS 27, and macOS 27 settings panel for Apple Intelligence and Siri.
“Extensions allow agents from installed apps to work with Siri, the Siri app and other features on your devices,” Gurman quoted a message inside test versions of the upcoming operating systems as reading.
Users will also be directed to a new App Store section from this menu to add additional AI services.
An earlier report by Bloomberg revealed that Apple is also working to bring a standalone Siri app to iPhones running iOS 27, which could make it more like a traditional chatbot, with the option to type queries, upload documents, and access past conversations. The company is also said to be adding Siri in the Spotlight search feature and adding new features like “Ask Siri” and “Write with Siri” toggles.
