A picture that looks like a dog? Four legs. Location for the last Olympics? Paris. A question that looks like it needs detailed answers? Start a bullet point list. Simple finetuning won't cure this problem, especially when the baked-in behavior is so overwhelmingly represented in training -- 2/

How do we prove that #AI can't do #maths? Real Mathematics (yes, "real" is a pun here): a+b+c = (a+b)+c = a+(b+c) AI Mathematics (well, floating point maths, really): >>> 0.1+0.2+0.3 0.6000000000000001 >>> 0.1+(0.2+0.3) 0.6 QED.

With a new, carefully annotated dataset and an automated evaluation metric we designed, we find that although LLMs are reasonably good at citing accurate sources most of the time, SOTA LLMs still cite incorrectly 5-28% of the time, and miss citations anywhere from 16% to an alarming 95% of the time.
