What issue are you seeing?

Codex CLI consistently returns the following error on one specific ChatGPT account: Selected model is at capacity.
Please try a different model. This does not appear to be a general model-capacity or local-machine issue. I tested the following:

• Creating a completely new Codex session does not fix the problem.
• Using the same affected account on another computer produces the same error.
• Other ChatGPT accounts work normally on the same computer and network.
• The problem therefore appears to follow the affected account rather than the device, local Codex configuration, session, or network.
