For example the other day i asked ChatGPT about a problem i had with some generated code that didn't compile. It then told me about a setting in the generator (nswag), that didn't exist. I told it that this setting does not exist and it said something like: "Sorry, my bad, try the following" and then kept inventing this setting with slightly different names and values over and over again. There are similar settings that exist, so it just hallucinated a tiny bit of text inside all the snippets that it learned from.
This is also not the first time this happened, most of the times i tried using AI for help with things, it just made up some nonsense and wasted my time with it.
