Were you trying to fine-tune the code in the same/original conversation that you started with?In the last two days, I was pushing ChatGPT to generate some PHP code. But after 15-18 updates, I stopped and realized that it was impossible to fine-tune the code to achieve the desired result.
If so, I find that when a conversation gets too long, the performance of ChatGPT gets lower.
Try starting a new conversation with the latest version of the code and then have ChatGPT fine-tune it.
