There is no actual feature called "Apple Intelligence", it's a marketing term for a handful of disparate features that they are applying everywhere.

Is the excellent OCR that lets me select text within an image Apple Intelligence? It uses local models. Or the prediction engine that optimizes battery life by backgrounding apps you're less likely to use, or applies updates while you're sleeping? What about the Latent Semantic Mapping text classification framework, which uses language models for fuzzy document search -- and has been around since 2007?

It wouldn't have made sense in the past to add a master kill switch for all these features, and it doesn't really make sense now to have one for the latest iteration.

Okay, I have an update.

It turns out that you CAN disable MOST of the Apple Intelligence features without compromising HomePod features or CarPlay by either:

A) Downloading and installing the profile I just created that does everything that follows below here (https://github.com/carlosonunez/bash-dotfiles/blob/main/ios-...), or

B) Doing these things:

1) Going to Settings > Siri and changing the "Language" to something other than "English (United States)." (I changed mine to "English (Canada).") This automatically disables Siri AI and restores Siri Classic. You'll need to go through voice training again though.

2) Going to Settings > Screen Time > Content & Privacy Restrictions > Siri and setting "Siri" to "Siri Classic."

3) Going to Settings > Screen Time > Content & Privacy Restrictions > Siri and setting all Apple Intelligence features (Writing/Math Assistance, Image Creation, Extensions) to "Blocked" or "Don't Allow"

4) Going to Settings > Messages and setting "Summarize Messages" to OFF

5) Going to Settings > Mail and setting "Summarize Messages" to OFF. (This might disappear after following step [3])

Steps 1 and 2 delete the Apple Intelligence models from your phone, giving you about 30GB of space back.

If you go to settings and disable Siri AI and Siri and then re-enable it you get the option "Try Siri AI" and "Use Siri Classic". This disabled most AI features from what I can see. The only one it didn't was notification prority.

There is a “Turn off Siri” option. Apple Intelligence & Siri are now effectively one.

So interesting. Before, it was great rejoicing, smugness and whatever other related expressions when headlines were saying "Apple is sitting out AI". Now, there's evidence that it isn't the case, and there's... mostly silence, and some mild disappointment. Everywhere else there is outrage and strong feeling expressed about how Y company is slipping AI into everything, but not when it comes to the fruit company. Of course they can do no wrong; it's always the user who's at fault and needs to adopt the correct(ed) path. Funny people.

Removing a single master switch and making users disable everything one by one sounds like a pretty pointless change. What was wrong with just letting people turn it all off?

I belive they are investing on Apple Intelligence a lot more, I have myself built a series of apps on top

Just like notifications in iOS that cannot be disabled globally.

Yeah, this kinda sucks.

I don’t really care what Apple calls it. If there was one switch before, why remove it?

If this stuff takes up a few gigs, just let people turn it all off. Easy.

That really is a bummer, especially on basic older models where 8-20Gb of space wasted on this gimmick even if turned off is not nothing.

Lucky you, I cannot enable it (EU).
