iOS 27 Will Let You Pick Your Own AI Model

Apple plans to give iPhone users the option to choose which AI model powers their device’s smart features in iOS 27. This news comes from Bloomberg’s Mark Gurman, who has a solid reputation for reporting on Apple. Instead of sticking with Apple’s built-in AI system, users may soon be able to select third-party chatbots like ChatGPT or Google Gemini to manage tasks across their entire phone.

What Apple Is Actually Planning

Currently, Apple Intelligence, which launched with iOS 18, handles tasks like summarizing notifications, rewriting text, and generating images using Apple’s own models. You can use ChatGPT, but it’s only available through Siri for specific questions — not as a system-wide alternative.

iOS 27 would change this setup. According to reports from TechCrunch and The Verge, Apple aims to integrate third-party AI models directly into Apple Intelligence. This means your preferred AI could take on tasks across apps, not just in a chatbot interface.

Think of it like selecting a default browser. Right now, you can install Chrome or Firefox on your iPhone, but Safari is the default. With iOS 27, you’d have the option to make a different AI your “default,” just like you can swap Safari for Chrome.

This update is expected to roll out with iOS 27, iPadOS 27, and macOS 27, which are all likely to launch in the fall of 2026.

Why Apple Is Doing This Now

Apple Intelligence received a mixed response upon launch. Many users felt the features were just incremental, and Siri’s AI upgrades came later than expected. Meanwhile, competitors like Google and Samsung have aggressively promoted their AI features on Android devices.

Opening the door to third-party models is a smart move. If users prefer Gemini’s writing suggestions or ChatGPT’s responses, Apple can keep them on the iPhone instead of losing them to Android. Apple maintains control over the hardware and operating system while allowing AI to become a plug-in feature rather than a standalone selling point.

Regulatory pressure also plays a role. European regulators have pushed Apple for greater openness and interoperability. By allowing competing AI models to integrate more deeply, Apple can respond to these concerns without fully opening up its App Store economics.

What This Means

If this plan goes through, it would mark the biggest shift in how AI operates on iPhones since the launch of Apple Intelligence. Here’s what you might expect:

• Writing help everywhere: If you prefer ChatGPT’s writing style, it could help with rewriting emails in Mail, suggesting replies in Messages, and cleaning up notes, all without switching apps.
• Smarter summaries: Notification summaries and web page recaps could utilize your favorite model instead of defaulting to Apple’s.
• Voice assistance: Siri queries that currently require approval to use ChatGPT might automatically run through your preferred model.

The caveat is that this is still a reported plan. Apple hasn’t officially announced iOS 27 yet, and details could change before the release.

Community Reactions

“This is actually huge if true. I’ve basically stopped using Siri for anything real because it can’t compete with ChatGPT. If I can set GPT-4o as my default, I might actually use AI on my phone.”

“Interesting move from Apple but I feel like most people don’t know or care which model is running. They just want it to work. The people who will use this are a small percentage.”

What To Watch

• WWDC 2026 (June): Apple’s annual developer conference is the most likely place for an official iOS 27 announcement. Keep an eye out for any mention of “AI extensions” or third-party model support during the keynote.
• Which AI companies sign on: Apple will need agreements with OpenAI, Google, and others to make this work. Partnerships announced before fall will indicate how serious this rollout is.
• Fall 2026 release: iOS 27 is expected to launch alongside new iPhone hardware in September or October 2026, giving users a chance to try out the new AI features.
• Regulatory response: If Apple promotes this as an openness initiative, watch how European regulators react. Their response could affect the feature’s availability at launch.
