My definition of a smart AI is an AI that is smart at mimicking a human - that means as a Game AI it would play an entirely different game of "mimicking a human" in essence.

The issue is that a lot of things a computer controlled player does is entirely too easy to implement with just a few random rolls. This starts to fall apart if you want to vary the difficulty. So you can get a credible if disdained "AI" in a lot less effort that say training a Neural net to predict what action a human would likely take next.

There simply is no "GPT-1" AI of playing a game yet much less a "GPT-3" level one and I do not think that it would be entirely easy at all to "tune" it in any way to get a consistent difficulty scale.
