If AI solves a Millennium Prize problem using ideas from human research, who gets the credit?

The flywheel effect is an interesting effect I discovered while researching. It makes the whole thing a self-reinforcing loop. When a human researcher uses an AI tool, or even just their own brain, to post or test a raw math theory and uploads it somewhere on the internet, they might post their progress on arXiv or somewhere else online. Then, AI companies might scrape it to train the next model, which could be the very reason the problem eventually gets solved intuitively. So my main question is: How do we assign credit when AI solves a Millennium Prize problem?
