I'm a data analyst and primary authority on the data model of a particular source system. Most questions for figures from that system that can't be answered directly and easily in the frontend end up with me.
I had a manager show me how some new LLM they were developing (which I had contributed some information about the model to) could quickly answer some questions that usually I have to answer manually, as part of a pitch to make me switch to his department so I can apply my expertise for improving this fancy AI instead of answering questions manually.
He entered a prompt, got a figure that I knew wasn't correct and I queried my data model for the same info, with a significantly different answer. Given how much said manager leaned on my expertise in the first place, he couldn't very well challenge my results and got all sheepish about how the AI still in development and all.
I don't know how that model arrived at that figure. I don't know if it generated and ran a query against the data I'd provided. I don't know if it just invented the number. I don't know how the devs would figure out the error and how to fix it. But I do know how to explain my own queries, how to investigate errors and (usually) how to find a solution.
Anyone who relies on a random text generator - no matter how complex that generation method to make it sound human - to generate facts is dangerously inept.
