ChatGPT is a nice interface/UI to the GPT models, but the models themselves are available via. an API and industry users will be using it via. the API.

Your report is very light on details. Your methodology is so short I do not know what you actually did.

This is probably sufficient for high school but a ML/AI report or paper would have a short introduction, maybe a review of existing research, a detailed methodology and a conclusion. It should also include references to external research. Ideally it would have an appendix that includes or references and links to the data (in the release?)

When doing research create a notebook documenting everything you did and the results. The notebook could just be a Google Doc.

You mentioned that you used ChatGPT to write the report. It is better to learn to write it yourself with assistance (grammar etc.) from ChatGPT.

I think the reply you got from OpenAI support was also generated by ChatGPT.

I want to commend you on taking the initiative to run experiments that allowed you to have some insight into what ChatGPT was doing on the backend. I have graded university students with far less initiative than you.

Keep experimenting and have fun… but if you have school exams coming up focus on studying for them rather than optimising your study using ChatGPT.
