We saw this model disappear from the catalog on 2026-07-30, and the catalogue carried no shutdown date for it beforehand.
Whatever price and context window this page showed before are no longer current, so they are not shown.
Everything that is going away - announced shutdowns and the rest of the silent removals. Other OpenAI models that are still listed.
Nearest model from the same vendor still listed with at least as much context:
openai/gpt-5.1-codex · $10.00 (was $10.00) / 1M out

Something in your code referenced a model that no longer exists. The same check runs over a whole repository:
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.
