I no longer have a Mac as I’ve moved over to Linux, but my iOS device leaves me very frustrated that I can no longer disable this AI stuff with a simple toggle.
It seems insane given that Apple’s competitors (Microsoft, Firefox, probably others) moved toward a global AI switch to make the choice easy for their customers.
Stop updating the OS. It gets a tad annoying that not all apps will continue to work, but that's what the web is for.
You can indeed disable it on ios and ipados. Turn off siri and change the language to the one that does not match your phone language and the models will be removed.
This is simply not true. Things like "writing tools" were moved out of the global siri checkbox and enabled by default, and now require you to use screen time content restrictions or modify settings in individual apps to turn off these features.
