This addressing variant is no longer listed in the catalogue, so a call to this exact id will not resolve.
The model itself did not go anywhere. Drop the suffix and the same model answers.
Call this id instead: google/gemini-3.1-pro-preview
We are not counting this as a removal. Every base model in that group stayed listed, so it is a change in how the catalogue addresses them rather than a retirement.

Other calls in the same code may use the same suffix:
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.
