Check your code for it
Run this in your repository. No install and no API key; it lists every OpenAI, Anthropic and Google model ID it finds, with its retirement date and replacement:
npx -y @aidriftline/driftline .Or look for this ID only: grep -rn "gpt-realtime-2025-08-28" . (misses aliases, Bedrock and Vertex names, and IDs split across lines).
To be warned automatically before the next retirement, add the free Driftline GitHub Action. It annotates the exact line in pull requests and can fail the build on retired models.
