Not the person you asked, but the OpenAI playground is a great place to start messing with their API, I wrote this to help: https://www.inputoutput.ai/tutorials/openai-playground-guide (note website is still a work in progress just got it going bear with me haha)
However, you need access to the GPT-4 API which you have to request separately. So even if you have GPT-4 with chatGPT Plus you might not have access to GPT-4 through the playground/API.
