I haven't run into this on macOS yet, but on iOS the space is not reclaimed in time to avoid running out of space even with Apple Intelligence turned off:

- Not enough space to update iOS without a computer tether, even though there would have been if that ~13GB on my phone was actually freed up. Instead I had to delete several GB on my phone.

- Recordings stopping due to lack of space, and again the 13GB LLM model on my phone was not removed before running into this.

I'm actually not where if/when I'll ever get my space back, and this is on iOS 26. It takes up even more space on iOS 27, and I don't have enough free space to waste on my 256GB phone.
