As stated by other users above, be careful using anything verbatim without knowing how it works, unless you’re willing to take that chance.
ChatGPT (based on 3.5) makes a lot of guesses and assumptions. GPT-4 is vastly improved and can produce outstanding results. Of course, GPT-4 requires a paid subscription. On the other hand, you can sign up for Bing which is now based on GPT-4. It requires a lot more prompting to get the results. But you essentially get the same results as GPT-4 in the end.
Best of luck on the optimizations.
