I think they are working with customers to improve the LLMs and tools for these use-cases. They almost certainly also hire experts to help filter out nonsense, pseudo-science and help curate trusted knowledge bases for training, but it will almost certainly be the customers who deliver the major results, and the AI companies will claim some of the credit. That said, patents for important medicine might help with the bottom line, so I could imagine partnerships and JVs.

Indeed.
