Researchers have found that large language models (LLMs) tend to parrot buggy code when tasked with completing flawed snippets.
That is to say, when shown a snippet of shoddy code and asked to fill in the blanks, AI models are just as likely to repeat the mistake as to fix it.
I was in that problem too but you can at least occationally tell it to “change the code further” and it can work.
Often YOU have to try and fix its code though its far from perfect…
