But that too didn't work:

The gpt-5.3-codex model is not yet available via API key access. It's currently available only through a ChatGPT subscription. We need to do additional security work before we can make it available via the API. For details, refer to this announcement.

As for the update announcement in the app, that's a bug, and it will be fixed in the next release.
