I asked it for something in Powershell and it did the same thing. I asked how it came up with that function and it said it doesn’t exist but if it did that’s how it would work.

Quality of output depends a lot on how common the code is in its training data. I would guess it’d be best at something like Python, with its wealth of teaching materials and examples out there.

When it starts going off the rails like that I also ask it to “check its work when its done”, and it seems to extend the amount of usable time before it loses the plot and suggests i use VBA or something.
