<<After glowing reviews, I spent $200 to try it out for my research. It hallucinated 8 of 10 references on a couple of different engineeribg topics.

For truly frontier stuff, it is still a waste of time.>> <<I've had the hallucination problem too, which renders it less than useful on any complex research project as far as I'm concerned.>> These quotes are from the link you posted. There are a lot more.
