Error code: 404 - {'error': {'message': 'The model `gpt-4o-2024-05-13` does not exist or you do not have access to it.', 'type': 'invalid_request_error', 'param': None, 'code': 'model_not_found'}}.

I am already a GPT PLUS member and can use GPT4 on the web page, but when I use my API key, it still says I don't have permission. This is my first time using an API key, so are GPT4 membership and GPT4 API key separate?

Please make sure you have followed the instructions correctly to obtain an OpenAI key with GPT vision access: https://github.com/abi/screenshot-to-code/blob/main/Troubleshooting.md
```

The error indicates the OpenAI API key lacks access to the GPT-4 model. Check the code that makes the OpenAI API call, likely in a file like `backend/openai_client.py` or similar. Verify the model name being used and ensure the API key has the correct permissions. The troubleshooting link provides guidance on obtaining a key with GPT-4 access. Test with a valid key and model to confirm resolution.
