Apple just confirmed something I honestly didn't expect to happen this soon.
iOS 27 will let you swap out Apple's AI models for third-party ones Claude, Gemini, ChatGPT across Siri, Writing Tools, and Image Playground. The feature is called "Extensions" internally, and Mark Gurman reported it two days ago.
This is a big deal. Apple's entire brand is built around keeping things inside the walled garden. Letting users choose their own AI model is about as un-Apple as it gets.
Why Is Apple Doing This?
Because they have no choice.
Apple Intelligence launched with a lot of promise and very little delivery. The company has been promising a smarter Siri since 2024. It's now mid-2026 and people are still waiting. The Google Gemini partnership was supposed to fix this, but even that integration has been delayed and spread across multiple iOS updates.
Meanwhile, Android users have had Gemini Live for a while. Samsung Galaxy S26 can place a Dunkin' Donuts order through DoorDash via voice. Siri still struggles with basic multi-step tasks.
Opening up to third-party models is Apple admitting they need more time and they'd rather give users options than lose them entirely.
What "Extensions" Actually Means
According to the Bloomberg report, Extensions will let installed apps surface their AI capabilities directly through Apple Intelligence features. So if you have Claude installed, you could use it inside Writing Tools or Image Playground on demand.
This applies to iOS 27, iPadOS 27, and macOS 27. Google and Anthropic models are apparently already being tested in internal builds.
The base layer will still be Apple's custom Gemini-licensed model. Extensions sit on top of that, giving you an override when you want something different.
WWDC 2026 Is June 8
This is all coming into focus at WWDC, which is five weeks away. iOS 27 is shaping up to be the biggest software release Apple has put out in years Gemini-powered Siri, Extensions, new photo editing tools, and potentially hints at the rumored touchscreen MacBook Pro.
For Mac users especially, the Extensions feature in macOS 27 could be genuinely useful. Imagine triggering Claude directly from any writing surface on your Mac without switching apps.
My Take
Apple has been slow. Painfully slow. But this move is smart. Instead of shipping a half-baked internal model, they're building a platform. Let the best models compete inside iOS. Users win, and Apple keeps the hardware and ecosystem lock-in.
Whether it actually works as advertised at launch is a different question. Apple Intelligence has a history of promises not matching reality.
WWDC on June 8 will tell us everything. I'll be watching.
What do you think will you switch to Claude or Gemini inside Siri, or are you waiting to see how it actually performs?

I needed something to help me prepare for therapy sessions. I kept showing up and blanking, then remembering everything I wanted to say on the drive home.
So I built Prelude.
It was my first time working with Swift. There were walls. Voice echo during agent playback, responses getting truncated, the AI starting to sound repetitive after a few exchanges. Figured them out one by one.
The app runs on Apple Intelligence and uses the premium on-device Apple voices for TTS. The whole thing works offline, nothing leaves your phone.
It has a voice agent that talks with you before your session, generates a structured brief from the conversation, and tracks your emotional trends week over week.
Free forever. No ads, no in-app purchases. Built it as a charity project for the mental health community.
Siri is Christian ?
So I made something with the shortcut app so Siri can give me the weather and everything like that (things on my calendar today) and at the end it assumed I was Christian. It gave me some random Bible emoji while saying “Enjoy your day, Tristan”. Luckily for her, I am Christian, but if it was a Muslim, it would have been disrespectful and could have made a scandal. Siri needs some updates guys.
