In the repository of the regular version of QualCoder, people reported the following error:
InvalidRequestError: The model 'gpt-4-1106-preview' does not exist or you do not have access to it. Learn more: https:// help.openai.com/en/articles/7102672-how-can-i-access-gpt-4.
If we follow the link provided (https://help.openai.com/en/articles/7102672-how-can-i-access-gpt-4), we find the following disclaimer:
"If you're a Pay-As-You-Go customer and you've made a successful payment of $1 or more, you'll be able to access the GPT-4 API"
So it seems that access to GPT-4 is not possible with the free credits OpenAI provides for new users, which is very annoying. As I understand it, you must pay at least once for credits. $5 (USD) seems to be the minimum amount.
Sorry for that. There is nothing I can do about it right now.
