Lots of things “have a utility function” in the colloquial sense that they can be usefully modeled as having consistent preferences. But sure, I’ll be somewhat skeptical if you want to continue “taking the utility-function perspective on stable diffusion is in some way useful for thinking about its alignment properties.”
Ah, you’re talking about guidance? That makes sense, but you could also take the perspective that guidance isn’t really playing the role of a utility function, it’s just nudging around this big dynamical system by small amounts.
no, I’m talking about the basic diffusion model underneath. It models the derivative of the probability density function, which seems reasonable to call a utility function to me. see my other comment for link

but diffusion specifically works by modeling the derivative of the utility function, yeah?
