Did I miss it or did the article not mention which LLM they tried, what prompts they've used and then they also mention zero-shot only, meaning no in-context learning? And they didn't think to tweak the instructions after it failed the first time? I don't know, doesn't seem like they really tried all that hard and basically just quickly checked the "yep, LLMs don't work here" box.
