Pricing, context window and lifecycle for openai/gpt-5.1-codex-mini, tracked from what the vendor publishes.
2026-07-23 - its vendor retired this model on that date, and the catalogue still lists it. Anything still calling it is running on borrowed time.
To find every place that calls 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.
