It doesn't really matter, but if you ask it the exact same prompt it will give different results everytime. And if you don't know how to write one properly yourself, you really shouldn't be blindly trusting Ai to produce something correctly. But these are the source of all future employment of developers and engineers who actually know things.

It does seem like a weirdly bad result. I got something more sensible that used DOMParser when I gave GPT-5 the following prompt:

> Write a JavaScript function for sanitizing arbitrary untrusted HTML input before setting a DOM element’s innerHTML attribute.

I won’t post it here in case someone tries to use it, but it wasn’t just doing regex munging.
