This is what I've been saying for years. I attended a tech demo of an AI assistant for a car's owners' manual. But they trained the manual into the model. Which means not only does it need retraining every edition, but it's imperfect. The models need to be trained to fetch and use documentation not vaguely recall infinitely many concepts. I would much rather have 27B parameters on how to code than 26B on stuff like numpy function listings. It's like they approached the problem from a closed notes hand written coding exam. Everyone hates those.
