Apple Just Put Google’s AI Inside Siri

Key takeaways

• Siri AI launched in beta on iPhone 15 Pro and newer. Simple tasks stay on Apple’s own models. Harder questions go through Apple’s Private Cloud Compute, which CNBC reported runs on Google Cloud.
• Apple hasn’t said if Siri AI shows clickable source links, the way Google’s AI Overviews or Perplexity do. That’s still an open question. It decides whether this new surface can ever send traffic back to a website.
• If your content already works for Gemini and Google AI Overviews, you don’t need to do anything extra for Siri. Same model, same rules. But the opposite is also true: if Gemini ignores your site now, it probably will on Siri too.
• Code found around the release hints that Apple built Siri to support Claude and ChatGPT as well, not just Gemini. Nothing’s confirmed yet, but it points to more model choice ahead, not less.

What actually shipped in iOS 27

Apple released iOS 27 on Monday, September 14, 2026. It comes with a rebuilt Siri called Siri AI, in beta, for iPhone 15 Pro and newer. You have to turn it on yourself in Settings, and some people land on a waitlist first. It can hold a conversation for more than 20 back-and-forth exchanges, read what’s on your screen, and act across Messages, Mail, Notes, and Calendar.

Apple confirmed its Google deal back in January 2026. Reports put the cost at around $1 billion a year. CNBC reported that Apple uses Gemini to help build its own on-device models, and that Apple’s Private Cloud Compute, used for harder Siri questions, runs on Google Cloud. Apple says none of that data gets stored or seen by Google. Siri AI is English-only for now. French, Japanese, Korean, Portuguese, and Spanish are coming next month, and it’s not launching yet in the EU or China for regulatory reasons. This follows a public beta TechCrunch covered back in July, when Apple first let more testers in.

The AEO angle: one model, two front doors

Here’s the part that actually matters for AEO. Siri AI runs on Gemini. That’s the same model family behind Google’s AI Overviews and the Gemini app, the ones we’ve already covered in our guide to AEO and our guide to GEO tools and agencies. Apple didn’t build a new model with its own view of the web. It built a second doorway into a model your content might already be reaching, or already missing.

That cuts both ways. If Gemini already cites your site through Google’s own products, you’re not starting from zero on Siri. You didn’t do anything Siri-specific, you’re just already feeding the model Apple licensed. But if Gemini ignores your site today, it was already missing one major surface. Now it’s likely missing a second one too, on every phone that updates, without you changing a thing.

We wrote recently about Cloudflare’s new default rules for AI crawlers, which decide whether Google’s crawler can even reach your page at all. That question still comes first. If your site blocks the crawlers Gemini trains on, you’re not just missing Google’s AI surfaces. You may now be missing Apple’s too.

The open question: does Siri cite anything?

Nothing in the reporting so far says whether Siri AI shows clickable links or credits a specific website, the way AI Overviews or Perplexity do. That’s a real gap. We’d rather say so plainly than assume Siri works like the AI search tools we usually cover.

If Siri AI turns out to be a closed conversation with no visible sources and no click-through, its value for AEO is mostly indirect. It’s a new place Gemini’s knowledge gets used, not a new place your brand or link can show up. If Apple adds visible sourcing later, especially once Siri AI reaches more languages and more countries, that would be worth tracking on its own. Right now, we don’t know which way this goes. Nobody outside Apple does.

What this means for your own AEO work

Don’t treat Siri AI as a separate thing to optimize for, at least not yet. There’s no known way to influence what Siri says about your brand that’s different from influencing what Gemini already says, since they run on the same model. The move that already works for Gemini and AI Overviews still applies here: write specific, well-sourced, crawlable content. We cover that in more detail in why AI isn’t citing a given page.

Keep an eye on two things: whether Apple adds visible sources to Siri AI as it expands, and whether that code evidence about Claude and ChatGPT turns into a real feature. If it does, “AEO for Siri” could mean tracking three different models inside one assistant instead of one.

How Web25 helps

Web25 tracks which AI surfaces are actually worth your attention, instead of treating every new AI product as something you need to chase. See our AEO/GEO/SEO service for how we approach it.

What to do next

Keep doing the specific, well-sourced content work that already helps with Gemini and Google AI Overviews. Siri AI runs on the same model for now, so that work already covers it. Want a full read on where your site stands with the AI tools that do cite sources today? Book a discovery call.
