Apple has developed a behind-the-scenes Extensions framework in iOS 27 designed to let users swap between AI assistants like ChatGPT, Anthropic’s Claude, and Google’s Gemini within Siri. However, the company opted not to announce this feature at WWDC 2026, reflecting complex regulatory, legal, and strategic considerations.
- iOS 27 beta includes a hidden third-party AI Extensions framework for Siri
- EU regulatory hurdles and legal conflicts delayed public rollout
- Apple prioritizes promoting its proprietary AI in Siri relaunch
What happened
Apple’s iOS 27 developer beta contains an unannounced Extensions framework intended to allow iPhone users to switch between third-party AI providers like ChatGPT, Anthropic's Claude, and Google’s Gemini inside Siri. The framework features a settings panel and a dedicated App Store section for enabling different AI assistants, although both are currently disabled by Apple's backend control.
Despite initial expectations that Apple would showcase this flexible AI integration at WWDC 2026, the company chose not to mention the framework during its keynote or related announcements. The reveal was withheld amid ongoing regulatory scrutiny, legal disputes, and messaging strategies, leaving the Extensions system in a hidden and inactive state for now.
Why it matters
This Extensions framework signals a major change in Apple’s approach to Siri AI, moving away from exclusive partnerships like the one with OpenAI's ChatGPT. By potentially opening Siri to multiple AI models, Apple aims to offer users choice and increase the assistant’s versatility. However, the timing of the launch is complicated by several factors including Apple’s confirmation that Siri AI will not roll out in the European Union as regulators reject key proposals on data access compatibility.
Additionally, OpenAI reportedly plans legal action against Apple over the original ChatGPT partnership, alleging that Apple hampered user interaction and revenue potential. Publicly launching a system that demotes ChatGPT's exclusivity in favor of broader AI competition could exacerbate these tensions. Furthermore, Apple is keen to promote its internally developed Siri AI powered by Google’s Gemini model, so introducing third-party model selection risks undermining the narrative of a cohesive Apple-controlled AI breakthrough.
What to watch next
Apple is expected to monitor ongoing regulatory negotiations closely, especially with the European Commission regarding the Digital Markets Act, before enabling the Extensions framework publicly. The company’s ability to reconcile offering third-party AI access with stringent data privacy and security requirements will be critical to future rollout decisions.
Legally, the outcome of OpenAI’s potential breach-of-contract claims against Apple may also influence how and when Apple activates the Extensions feature. Meanwhile, user and developer reception to the newly rebuilt Siri and its current performance in public beta—which is described as functional but with notable limitations—will inform Apple’s strategic messaging and technical priorities in evolving the assistant’s capabilities and third-party ecosystem.
