I've run into the exact same thing looking for knitting references. I think it just makes most stuff up. My idiot boss is obsessed with it so I played with it one night since it will be my replacement according to him.

Every time I opened a new chat and asked the same question, I was given a different answer. Dead links for everything. Articles that don't seem to exist. Being a 'language model' I'm sure it's not designed for research like my boss and so many others are assuming.

As for the coding aspect, it feels like it's just scraping git and Stackoverflow.
