Since beta 2 I think, it seems Foundation models are not accessible if Siri AI is not enabled.
I'm on Mac OS, and not sure how it works on iOS, but does that mean that Foundation Models will not be usable if Siri AI is not enabled (Europe)?
Foundation models tied to Siri in Mac OS beta 2
The Foundation Models framework should be available in Europe even if Siri AI is not enabled. Please file a bug report via Feedback Assistant and be sure to include a sysdiagnose to help us investigate.
