Interesting article, but correct me if I am wrong, you didn't actually use ChatGPT to generate the reviews but davinci which is a GPT-3 model. While is true that ChatGPT is a fine-tuned GPT-3.5 with a custom training procedure that uses RL and human feedback (similar with InstructGPT) there is still a difference, so the title might be a bit misleading.

Thanks!
