The model `gpt-4` does not exist

Im trying to set up a workflow and getting this error message. I need some guidance on setting this up properly.

Hi @bightx,

The error message you're seeing is from OpenAI. It appears that you either don't have the required plan to access GPT-4, or you lack sufficient credits. Please contact OpenAI's support team for further clarification on the issue.
