Apple Just Rebuilt Siri From Scratch — But Here's the Plot Twist Nobody Expected

I use Siri every single day. And for years, I've complained about it being slow, wrong, and frankly embarrassing compared to what Google Assistant and ChatGPT can do. So when Apple announced they had rebuilt Siri from the ground up, I was cautiously optimistic. Then I found out who actually built the new AI powering it — and my jaw dropped.

Apple Just Opened the English Public Beta of the New Siri

As of today, September 15, 2026, Apple has opened the English public beta of its completely rebuilt Siri AI assistant. This is a major milestone. The old Siri — which Apple had been quietly embarrassed by for years — is being replaced with a system that is genuinely good at understanding and executing complex requests. We're talking about a Siri that can actually reason, maintain context across a conversation, and coordinate with apps in ways that the old assistant never could.

If you're in the beta, expect it to feel like a completely different product. This isn't a patch. It's a rebuild.

The Twist: Google Built the AI Inside

Here's what nobody saw coming: the new Siri is powered by models custom-built with Google, running on Gemini. Let that sink in for a second. Apple — the company that built its entire brand around being independent, private, and ecosystem-locked — is now running Google's AI on your iPhone.

This is a historic partnership between two companies that have been competing fiercely for decades. Apple and Google split hundreds of billions of dollars every year fighting over search deals, browser dominance, and smartphone market share. And now they're sharing the most intimate AI experience on your device: your personal assistant.

Why Would Apple Do This?

Simple: they were losing. OpenAI's ChatGPT and Google's Gemini were so far ahead in raw AI capability that Apple's homegrown models couldn't compete. Rather than fall years behind in the AI race, Apple made a pragmatic call: partner with the best model available and focus their engineering on the experience layer, privacy guarantees, and on-device processing.

It's a smart move, even if it's a humbling one. Apple's strength has always been user experience and trust. Letting Google's AI handle the heavy lifting while Apple wraps it in its privacy-first infrastructure is a reasonable division of labor. Whether users see it that way is another question.

What This Means for Your Privacy

This is the question everyone's asking. Apple has consistently promised that Siri requests are processed on-device or anonymized before reaching servers. With Gemini powering the backend, data will inevitably touch Google's infrastructure at some level. Apple hasn't been fully transparent about exactly where the data boundary lies.

If you're someone who uses Siri for sensitive requests — medical questions, financial lookups, personal reminders — you should read Apple's updated privacy terms carefully before enabling the new beta. The experience will be dramatically better, but the privacy calculus has changed.

5 Things the New Siri Can Do That the Old One Couldn't

  • Maintain context across a multi-turn conversation without losing the thread
  • Take complex, multi-step actions across apps (like booking dinner, adding it to your calendar, and texting your friends — in one request)
  • Actually understand what you mean when you're vague or use shorthand
  • Generate text, summarize emails, and draft messages in your personal style
  • Answer difficult factual questions with nuance instead of just googling them

What It Means for Google and the Broader AI Market

For Google, this is a massive win. Getting Gemini onto hundreds of millions of iPhones validates the model as enterprise and consumer grade at the highest level. For the AI industry broadly, it signals that no company — not even Apple — can afford to go it alone in building frontier AI models. The talent requirements, compute costs, and research depth needed to build a competitive AI assistant are simply too high.

We're entering an era where AI capabilities will be concentrated among a small number of providers (Google, OpenAI, Anthropic, Meta) who license to everyone else. Apple just made the most visible endorsement of that model possible.

My Take

I'll be joining the beta today. If the new Siri is even half as capable as what Google Gemini can do in a standalone app, it will be a massive improvement over what we've had. The privacy concerns are real and worth watching, but for most users, the experience upgrade will outweigh the theoretical risk. Apple earned a lot of trust over the years — this is them spending some of it. Whether the bet pays off depends on whether the AI actually works.
