openai codex gpt-5-3-shutdown openclaw migration gpt-5-5

Summary

OpenAI discontinued support for the gpt-5.3-codex model, impacting OpenClaw users who now need to switch to the gpt-5.5 model via Codex.

Dear Community, I’ve been using OpenClaw with Codex account via OAUTH for a while now, but today OpenAI dropped the support for the model I was using: OpenAI-codex/gpt-5.3-codex. I belive this change impacted many of openclaw users. Once you try to work with Openclaw you get the error message: {"detail":"The 'gpt-5.3-codex' model is not supported when using Codex with a ChatGPT account."} My question is: how to switch openclaw to gpt-5.5 model via codex?
