Apple is preparing to open Siri to outside AI models for the first time, with a new extensions framework set to debut at WWDC on June 8 as part of iOS 27, iPadOS 27 and macOS 27, according to reporting cited on AI Chat Daily. The change marks the company's clearest concession yet that its in-house assistant cannot keep pace with the current generation of large language models.
Mark Gurman first sketched the framework in March, and 9to5Mac has now confirmed it will ship alongside the summer software releases. Inside Apple Intelligence settings, users will be able to choose which model handles which type of request, plugging in Anthropic's Claude, Google's Gemini or OpenAI's ChatGPT depending on the task.
"What this means is that you're gonna be able to go into settings in Apple intelligence and Siri, and they're gonna pick what model handles what," Jaeden Schafer said on the podcast, describing a configuration layer that turns Siri into a routing surface rather than a single assistant. Users will also be able to attach a custom voice to each model, so the response style shifts depending on which back end answered.
Key facts
- 01Apple will ship a Siri extensions framework in iOS 27, iPadOS 27 and macOS 27 at WWDC on June 8, letting users route queries to Claude, Gemini or ChatGPT.
- 02Users will be able to assign different third-party models to different tasks inside Apple Intelligence settings, with custom voices per model.
- 03A separate lawsuit will force Apple to pay roughly $100 per device to buyers of the iPhone 15 Pro and iPhone 16, because Apple Intelligence did not ship at launch.
- 04Mark Gurman first reported the extensions framework in March; 9to5Mac has now confirmed a WWDC ship date.
The shift represents a reversal of years of strategy in Cupertino, where Siri has been built and maintained as a proprietary stack tightly bound to Apple's own services. Allowing third-party models direct access to a system-level assistant hands real estate to rivals on more than a billion active iPhones, but it also gives Apple a way to ship competitive features without having to match frontier labs model-for-model.
“The customization is going to be nice and hopefully a good enough feature to apologize to everyone for why this has all taken so long”— Jaeden Schafer
The announcement is landing alongside a costly piece of legal housekeeping. Apple is facing a settlement that will require payouts to buyers of the iPhone 15 Pro and iPhone 16, the devices whose marketing leaned heavily on Apple Intelligence features that did not arrive on schedule. Schafer said Apple will "have to pay $100 back to everyone that bought an iPhone 15 pro and an iPhone 16 because Apple intelligence didn't ship when those were launched and the marketing all basically pointed to it shipping."
The combination of the WWDC opening and the refund is unusually candid for Apple, which rarely concedes product missteps so directly. By bolting on Claude, Gemini and ChatGPT, the company is effectively acknowledging that the assistant it sold in 2024 advertising will only become credible once outside models are allowed to do the heavy lifting.
For Anthropic, Google and OpenAI, distribution at the operating-system level is the prize. Each has spent the past year fighting for default placement inside browsers, productivity suites and phones; an Apple-blessed slot inside Siri puts their models in front of users who would never download a separate chatbot app. The custom-voice hook also gives each provider a way to build brand identity inside an Apple shell.
Schafer framed the customization as part apology, part feature. "The customization is going to be nice and hopefully a good enough feature to apologize to everyone for why this has all taken so long," he said, tying the WWDC reveal directly to the refund cheques about to land in customers' accounts. Whether iPhone owners accept the trade will become clear once iOS 27 ships in the autumn.
