Easily solved, pairs of models, one which would rather say IDK, one which would rather guess. Most AI agents would want the IDK version.

Anyone who claims something is easy to solve should be forced to implement their solution.

Maybe, but I don't know. Although I would like to channel as many snarky remarks as I could, to be more constructive, I would use the IDK model, as I have with programming questions and use the psychotic one for questions like "are we in a simulation?" And "Yes, I would like fries with that and a large orange drink."
