Apple is considering a significant shift in how it operates Siri by potentially running its next-generation chatbot on Google's cloud infrastructure rather than entirely on its own Private Cloud Compute servers, according to Bloomberg's Mark Gurman.

In yesterday's report detailing Apple's plans to turn Siri into a chatbot in iOS 27, Gurman said that the company is in discussions with Google about hosting the forthcoming Siri chatbot on Google-owned servers powered by Tensor Processing Units (TPUs), a class of custom chips designed specifically for large-scale artificial intelligence workloads. The arrangement would mark a major departure from Apple's emphasis on processing user requests either directly on-device or through its own tightly controlled Private Cloud Compute infrastructure.



The near-term Siri improvements in iOS 26.4 are still expected to run on Apple's own Private Cloud Compute servers, which the company unveiled in 2024 as a privacy-focused alternative to on-device processing. Private Cloud Compute relies on Apple-designed servers built around high-end Mac chips, and Apple has positioned the system as one where user data is processed temporarily and not retained, not even being accessible to Apple itself. Those claims have been central to Apple's public messaging around Apple Intelligence.

The more advanced Siri chatbot planned for the following major operating system update is expected to rely on a newer and more capable large language model developed by Google. This model is internally referred to as Apple Foundation Models version 11 and is comparable in capability to Google's latest Gemini models. Running such a model at scale may exceed the practical capacity of Apple's current Private Cloud Compute infrastructure, prompting the need to use Google's significantly larger, specialized cloud footprint and AI hardware.

The possibility of running Siri requests on Google servers does not necessarily mean Google would gain access to user data in a conventional sense. Apple already relies on third-party cloud providers, including Google, for parts of iCloud's infrastructure, while retaining control over encryption keys and data handling policies.

Well…

That’s a great way to make sure that I never use it.

Third parties already host Apple services. Doesn’t mean they get access.

There were reports a while ago of google making their own private cloud compute. Probably all linked to a deal with Apple.

Everyone needs to calm down until we get actual details.

So is Gurman saying that the previous announcement about Apple using an instance of Gemini on its own Private Cloud platform as the Siri back end will no longer be the case for iOS 27, or is this chatbot Siri a separate thing that would run on Google’s servers?

Edit - And I just saw the tweet from Gurman saying the “new new” Siri in iOS 27 is a subsequent update to the new Siri coming in iOS 26.4 and that they are separate.

Google pays Apple billions per year to be the default search engine in Safari.

The former head of Google’s Gemini AI team now heads Apple Intelligence.

Apple announced that Google’s Gemini would be the LLM powering not only Siri but Apple Intelligence itself.

Apple announced that Gemini would be run on Apple servers and not leak private data back to Googje.

Now it looks like Apple’s white label version of Google’s Gemini will actually run on Google’s servers as it is being tweaked by the former Gemini head designer while at Google who now runs Apple Intelligence so that in part in can serve up better search results in Google which Google pays Apple billions each year to be the default search engine in Apple’s Safari.

Legit question….why did I pay so much for my iPixel 15 Pro when I could have bought a genuine Pixel phone AND a high end Chromebook for the same price?

In all seriousness: Apple has lost its compass, if they are going through with this. Whatever happened to "on-device privacy"…

It could be that, for the most part, Gen Y and Z don't care about privacy as much as Boomers and Xers. One thing clear about business is that if privacy doesn't add to the bottom line, no effort will be made to protect it.
 
I feel like people do not really understand how hosting of another company data works for the service provider. Seeing that I work at one of the "hyperscaler" companies that literally everyone heard of, and we host data for bajillion companies, I can confidently tell you that it is absolutely possible to have data in one's datacenter where the company hosting it does not have access at all, even if they tried.

Your iCloud backups today could already be hosted in Google datacenter.

This is not a problem that is unsolved; Apple could run literally everything they have in a Google datacenter with a dedicated model, private encryption keys etc. and it would make zero difference to anyone here.

The question is "would Google have access to customer data on application layer" and I am going to guess the answer to that will be "No" just like today your iCloud backups are not something Google can read.

The one thing crystal clear based on replies in this thread is people absolutely do not understand how datacentres work or how existing Apple services (hosted by Google & others) are able to keep your data private
 
No issues there, Google Cloud servers are completely segregated from Google proper, if banks, healthcare, government and others can securely run there, Apple can too.

Stop posting facts. You’re going to upset the people whining about Apple throwing away your privacy over a piece of technology they don’t understand.
 
I don't care whether they run it on Apples server, Googles or OpenAIs. Just give me a decent Siri that was promised a hell of a long time ago.
This. And let me integrate it/allow it access to as much or as little personal info *I* find acceptable.

I need flexibility, not a nanny.

I can imagine Apple having a gigantic challenges to scale their cloud capacity from 0 to serving 2 billion devices overnight. They might have underestimated how much of the compute needs to happen in cloud (vs what they can run on device).

Even with that, they should not compromise their only differentiation (privacy that people actually trust).

Low ramp might be the only viable solution. If that is required, so be it.
