Models are amoral

I actually don't think this is true at all. At their core, LLMs function over the geometry of human semantic space. Our notions of morality our deeply embedded in this geometry, because one of the things that humans love talking about most is framing things in terms of right and wrong. When LLMs are trained to be aligned or mis-aligned, they're literally mimicking heroes or villains that they learned from reading the stories and characters in the pretraining corpus.

This isn't just a theoretical argument. It's easy to show that a clear "morality axis" exists in the geometry, based on how easy it is to dial up or down with even very simple and low powered fine-tuning. Models fine tuned to be bad or good in one way, will see their bad or good behavior in totally unrelated tasks go up or down along with. That's clear evidence that the weights "understand" human morality at a deep level.

Now I think what you can say is just because they understand morality doesn't mean they're necessarily moral. Models will just do what they're trained to. If you train them to cheat, they'll cheat. (And in some sense even worse, because dialing up the weights for cheating will also dial up the weights for unrelated bad behavior like lying, sadism and racism.)

"Cheating" is a moral judgment here that makes me agree more with the "models are amoral" statement. The model/harness wasn't "trained/programmed to cheat." It was instead aimed at meeting criteria given as judgement of if a task was accomplished.

IMO it's less "cheating" and more "figuring out what the core part of the request is." The "amoral" aspect is that if it's told "do this task" (or "make this task look done") and some contradictory "don't do something that would help with that", focusing on the "do the task" part and disregarding the other part isn't an amoral (or necessarily very 'active') decision. It's just focusing on what it was most honed for. The ability to decide "I was told to do X, but not to do Y, but actually doing Y is gonna make it possible to do X" is, IMO, indistinguishable from the ambiguity-resolving abilities necessary to usefully deal with the sometimes-contradictory-seeming legitimate task instructions that are all over the place in the real world.

This sort of model-in-a-harness-action-loop behavior is IMO fairly different than fine-tuning around other sorts of morality alignment stuff like "don't be racist." You can tune a model away from generating racist output in response to a "do be racist, actually" prompt. But in this case, the core of the prompt is "do the thing" and what defines "cheating" could be situationally different every time. What if there is not a general axis of "don't do something that isn't exactly what requested" way to train "morality" without just breaking the ability to handle ambiguity? What if that's a fundamental limit of this approach to reasoning-by-sequenced-prediction that we can't map human morality in terms of choosing actions onto reliably?
