OPENAI_API_KEY for GPT-4

[gbenaa]

Hi - this looks like such a great project.

You say "It's also recommended that you use at least GPT-4, preferably GPT-4-32k.

Set your OpenAI API key and install the python requirements:

export OPENAI_API_KEY="

My key only permits GPT-3.5 at present, am on the waiting list for GPT-4 - I presume I won't be able to use your appliction in the meantime?
