Of course they do. They have such a huge parameter maps. You need to be able to guide it through the map, so it starts making the right connections. Even in the Sonnet 3.7 days, it became clear to me, that if I have want efficient code out of it, I need to really take care of the context. If I just let it research a problem, it will mess up most of the time. If I tell it to study A, B, C and then present problem D, it will solve it perfectly. And it's true even with the current top models.
