In my experience consultants are using an absolute ton of chatGPT

Yes, daily. It's extremely useful, superior to internal search while combining the internal knowledge base with ChatGPT's

YMMV wrt your experience and luck.

I’m a pretty experienced developer and I struggle to get any useful information out of LLMs for any non-trivial task.

At my job (at an LLM-based search company) our CTO uses it on occasion (I can tell by the contortions in his AI code that isn’t present in his handwritten code. I rarely need to fix the former)

And I think our interns used it for a demo one week, but I don’t think it’s very common at my company.
