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.
