Andrej Karpathy says that, for his repository, coding models often add unnecessary code and complexity, misunderstand the code, and use deprecated APIs, so their output is not net useful to him.

“there and so i just kind of feel like they're bloating the code base they're bloating the complexity they keep misunderstanding they're using deprecated apis a bunch of times so it's a total mess um and uh it's just it's just not net useful i can go in i can clean it up but it's not not useful i also feel like it's kind of annoying to have to like type out what i want in english because it's just too much typing like if i just navigate to the part of the code that i want and i go where i where i know the code has to appear and i start typing out the first three letters”
