Observed by diffing the live catalogue every day. A model that simply stops being listed was never on anyone's calendar, because there was no date to put on one.

The vendor published a retirement date and its page no longer carries one. The model is still listed and still callable; what changed is what the vendor says about it.

Models their vendor has already retired that the catalogue no longer lists at all. These are not this week's news - they are what is still sitting in code written last year.

Reading a list is work. This checks a whole repository against all of it:
curl -sO https://neosignal-ai.vercel.app/check.py
python check.py .
It names every model your repository calls that is already gone, and exits non-zero so the next one fails the build instead of production.
