There is an implicit assumption here that models are being ‘trained’, perhaps because LLMs are a hot topic. By models we are usually talking about things like decision trees or regression models or Markov models that put in risk probabilities of various eventualities based on patient characteristics.

If these things were being based on traditional AI techniques instead of neural network techniques, why are they getting implemented now (when, as you say, LLMs are the hot topic) instead of a decade or so ago when that other stuff was in vogue?
I think the assumption that they’re using training data is a very good one in the absence of evidence to the contrary.
I’ve never heard of Peri until this thread so I have no opinion of his motivations, but I do watch The 8-Bit Guy and I never got the impression that he was in it for the money. What makes you think that?
