Your iPhone Is About to Let You Pick Your AI

If you have ever asked Siri to do something simple and gotten a shrug back, you are not alone. For about fifteen years, Apple's assistant has been the thing you turn off after a week. So when Apple spent nearly its entire developer conference this month rebuilding Siri from the ground up, that alone would have been a story. But the more interesting part is the feature Apple built, tested, and then chose not to show anyone.

Let me walk you through what actually happened at WWDC, because there are two stories tangled together here, and the quieter one matters more for where this is all heading.

The do-over Apple owed everyone

WWDC is Apple's Worldwide Developers Conference, the big June event where it previews the next year of software. This year, on June 8, Apple used most of the keynote to unveil "Siri AI," which it called the most significant overhaul of the assistant in fifteen years ¹.

The honest backstory is that Apple had promised a smarter Siri back in 2024, couldn't ship it, and got sued over it. The company quietly settled a $250 million class action last month over advertising features that weren't ready ². Tim Cook, in what turned out to be his final keynote before handing the CEO role to hardware chief John Ternus in September, admitted on stage that Apple Intelligence had "not yet delivered on everything we promised" ². That is a rare thing to hear from Apple, and it tells you how much ground they were trying to make up.

The new Siri arrives as a standalone app on iPhone, iPad, and Mac. It can search across your messages, emails, and photos, answer questions about what's on your screen, run multi-step commands across apps, and go out to the web for fresh information ¹. In other words, it finally behaves like the chatbots you've probably already been using.

The plot twist: Siri now runs on Google

Here's the part that raised eyebrows. The brains behind the new Siri aren't Apple's. Multiple reports confirmed that Siri AI runs on a custom Google Gemini model of roughly 1.2 trillion parameters, licensed in a deal worth about $1 billion a year ².

A quick translation, since "parameters" gets thrown around a lot. Think of parameters as the adjustable dials inside an AI model that get tuned during training. More dials, very loosely, means more capacity to handle complicated requests. A 1.2-trillion-parameter model is a large, capable one, and Apple is renting it rather than building its own.

Apple wrapped that decision in a privacy story it has practiced for years. Requests get sorted into three tiers: simple stuff stays on your device, medium tasks run through Apple's own encrypted "Private Cloud Compute," and only the heaviest reasoning gets routed to Google's cloud ¹. Apple says those queries are processed without retaining anything, and that its contract bars Google from training future models on your data ². Whether you find that reassuring is up to you, but the engineering effort to keep Google's model at arm's length is real.

The takeaway for you: Apple essentially admitted it couldn't build a competitive AI model in-house on the timeline it needed, so it bought distribution and brought in a partner. That's not a scandal. It's the same "use the best tool available" calculation a lot of us make at work every day.

The feature Apple hid

Now the quieter, more interesting story. Buried in the iOS 27 developer beta is a feature Apple never mentioned on stage: an "Extensions" framework that would let you swap between ChatGPT, Anthropic's Claude, and Google's Gemini directly inside Siri ³.

According to Bloomberg's Mark Gurman, the system is fully built, including a settings panel and a dedicated App Store section, but Apple has it toggled off on the back end ³. TechCrunch described the concept earlier this year as a "choose your own adventure of AI models" ³. The idea is that instead of being locked to one assistant, you could route different jobs to different providers. Writing help from one model, image generation from another, open-ended questions from a third ³.

So why hide something this useful? Three reasons, all of them about timing rather than technology ³. Apple is in a standoff with European regulators over how much access rival assistants get, and announcing an "invite everyone in" feature would have undercut its argument there. OpenAI is reportedly weighing legal action over the original 2024 ChatGPT deal, and a model-picker that demotes ChatGPT to one option among several would have poured fuel on that fire. And after two years of overpromising, Apple wanted its own Siri to stand on its own before letting users replace it on day one.

There's a humbling footnote, too. Gurman's hands-on review described the new Siri as functional but buggy, with slow responses and misunderstood requests, roughly where the leading chatbots were about six months ago ³. The rebuild is real, but it is not magic, and Apple knows it.

What this means if you're not an Apple obsessive

You might be reading this thinking, fine, but I just want my phone to work. Fair. Here's why this is worth your attention anyway.

First, the era of being locked into one AI assistant is ending, even on the most locked-down platform there is. When the company famous for walled gardens builds a switch to let you pick Claude or Gemini or ChatGPT, the direction of travel is clear. The skill that matters isn't loyalty to one tool. It's knowing which tool fits which job, because soon you'll be choosing right from your home screen.

Second, this is a useful reminder that even Apple rents its AI now. If the most resourced company on earth decided buying access to a model beat building one, then the pressure you might feel at work to have it all figured out in-house is probably overblown. Picking good partners is a legitimate strategy, not a cop-out.

Third, keep your expectations grounded. A rebuilt Siri that's "competitive with six months ago" is genuine progress and still a long way from doing your job for you ¹. That gap, between the keynote promise and the thing in your pocket, is exactly where calm, capable people add value. You don't need to outrun the hype. You just need to stay a little more curious than the person next to you.

The public beta arrives in July, with the full release this fall alongside the next iPhone ¹. Whether the model-picker ships with it is still an open question ³. But the bigger shift is already visible: your phone is slowly becoming a place where you choose your AI, not where one gets chosen for you. That's a small amount of power landing in your hands, and learning to use it well is going to be a quietly valuable skill.
