From my understanding of the architecture, Apple and Google have basically developed a fork of Gemini that is built to run on Apple's PCC. There is no data being sent to any Google servers.

From this MacRumors article:

"The new architecture centers on Apple Foundation Models co-developed with Google, which Apple says are adapted to run both on-device and on servers through its existing Private Cloud Compute infrastructure."

And

"The company reiterated that Apple Intelligence relies on on-device processing and Private Cloud Compute, with a promise that user data is only used to execute the immediate request and is not accessible to Apple or third parties. Apple added that outside experts can verify those privacy guarantees "at any time.""

That seems to conflict with the recent security blog that says they are using Google Cloud infra and NVIDIA GPUs with PCC now [0].

They are allowing it to run on Intel and NVIDIA and Google chips meeting certain requirements now too instead of just Apple silicon because they think they’re secure enough now, but I suspect this decision might have been pushed by the need for Siri to be useful.

I still definitely think it’s better than what every other company is trying to do (like running a variant of OpenClaw 24/7 forwarding data to Anthropic, OpenAI, Google, and every other provider they can support).

Ah thank you for that, the MacRumors article was misleading to not even have mentioned this.
