Regression (worked before, now fails)

No

Summary

Recently, OpenClaw stopped working for me with Codex models other than openai-codex/gpt-5.4 when using a ChatGPT/Codex OAuth account.

gpt-5.1, gpt-5.2, and gpt-5.3 variants all fail with:
{"detail":"The 'gpt-5.1' model is not supported when using Codex with a ChatGPT account."}

(The model name in the error changes depending on which one I try.)

This worked previously, and it seems like other users are seeing similar behavior.

Steps to reproduce

1. Authenticate with openai-codex / ChatGPT-Codex OAuth
2. Try using a non-gpt-5.4 Codex model, for example a gpt-5.1, gpt-5.2, or gpt-5.3 variant
3. Observe the request fail with the unsupported-model error above

Expected behavior

Not receive the error and just get a response back from the model

Actual behavior

{"detail":"The 'gpt-5.1' model is not supported when using Codex with a ChatGPT account."}

Notes

• This started happening recently after previously working
• It looks like openai-codex/gpt-5.4 is still usable, but the other Codex variants are not
• Not sure whether the refresh_token_reused status is related, or just a separate auth cleanup issue
