Novel is a tricky word. In this case, the LLM produced a python program that was similar to other programs in its corpus, and this oython program generated examples of hypergraphs that hadn't been seen before.

That's a new result, but I don't know about novel. The technique was the same as earlier work in this vein. And it seems like not much computational power was needed at all. (The article mentions that an undergrad left a laptop running overnight to produce one of the previous results, that's absolute peanuts when compared to most computational research).
