extent analysis

TL;DR

The issue is likely due to using a ChatGPT account with the gpt-5.3-codex-spark model, which is not supported, and a workaround is to use a different model or account type.

Guidance

  • Verify that the error message is related to the account type by checking the error message: The 'gpt-5.3-codex-spark' model is not supported when using Codex with a ChatGPT account.
  • Try using a different model that is supported with ChatGPT accounts to see if the issue persists.
  • Consider using an API account instead of a ChatGPT account to access the gpt-5.3-codex-spark model.
  • Check the usage limits for the gpt-5.3-codex-spark model to ensure that the issue is not related to exceeding the limits.

Example

No code snippet is provided as it is not necessary for this issue.

Notes

The issue seems to be specific to the combination of the gpt-5.3-codex-spark model and ChatGPT accounts. The usage limits for the model do not seem to be the cause of the issue.

Recommendation

Apply workaround: Use a different model or account type, as the gpt-5.3-codex-spark model is not supported with ChatGPT accounts.
