This is why there's the "thin copyright" doctrine in the US. It comes up often in music cases, since a lot of pop music is trying to do the same thing. You can take a bunch of uncopyrightable elements, mix them together in a creative way, and get copyright over that. But that's a very "thin" copyright since the creativity is less.
I don't think thin copyright would apply to AI model weights, since those are trained entirely by an automated process. Hyperparameters are selected primarily for functionality and not creative merit. And the actual model architectures themselves would be the subject of patents, not copyright; since they're ideas, not expressions of an idea.
