From what I understand they used a diffusion model (diffdock) to predict the mechanism. These types of models are not LLMs that need to be trained on text

There are probably 37,392 papers on this. So your "should" is probably just impossible for humans.

This is such a ridiculous argument. They could have read five papers, couldn’t they?

Picking up five needles is trivial. Picking up five needles in 50000 haystacks is difficult.

How do they know which five papers to read?
