Well, I would say “utilitarian”, but that word seems to be taken. I mean that the model calculates utilities associated with its possible actions—and then picks the action with the highest utility.
But that is exactly what this wrapping in a post-hoc utility function doesn’t do. The model first picks an action in whatever way it does, then labels that with utility 1.
If I stick a hamburger on my car, the car is still a car—but the hamburger plays no part in what makes it a car.
AFAICS, I never made the corresponding claim—that the utility function was part of what made the model a model.
How else can I understand your words “utility-based models”? This is no more a utility-based model than a hamburger on a car is a hamburger-based car.
