Well because it could be an extra ~20GB which is not nothing if you have a 256GB disk.

By that logic why not fill the hard drive with OS data? This is a company mind you that still sells some laptops with a base configuration of 256GB, so 10-20GB isn't an insignificant amount to many users especially when it's taken by a feature they may not even use.

It's 14GB of something I don't want, need, nor have any use for, on a machine that is notorious for making storage upgrades difficult.

Friendly reminder:

Many apps (like dictation apps) ship with their own models totally separate from Apple Intelligence.

For example, Co-Typist [1] is very useful, but it requires a model installed with it, ranging from Gemma 3 1B at 0.8 GB to Gemma 4 26B A4B Pro at 15.7 GB. It recommended Gemma E2B (3.2 GB) for my 16 GB, M1 Pro MacBook Pro.

It works really well; the autocompletion is so good, it knows what I'm going to type before I do!

Here's the thing: you may not be aware of the amount of storage being used by models in various 3rd-party apps.

The open-source app What The Model [2] scans your machine and reports all the models it finds and gives you the total amount of storage being used.

because some people don't want AI and would rather even the files were not present in their computer.
