    Codex model availability update

    We're updating model availability for users who sign in with ChatGPT. Starting April 7, the model picker no longer shows gpt-5.2-codex, gpt-5.1-codex-mini, gpt-5.1-codex-max, gpt-5.1-codex, gpt-5.1, or gpt-5. On April 14, we'll remove those models from Codex for ChatGPT sign-in. Users can still choose from gpt-5.4, gpt-5.4-mini, gpt-5.3-codex, and gpt-5.2. ChatGPT Pro users can also choose gpt-5.3-codex-spark. To use another API-supported model in Codex, sign in with an API key or configure a model provider.
