IANAL, but weights are probably not copyrightable because they are “useful” i.e. they have intrinsic utilitarian function as they are necessary for a model to function as described. Useful things can not be copyrighted, only patented. This is the key difference between the two. For works that are useful and creative, only the non-functional aspects can be copyrighted.
Maybe a published copy of the weights might be copyrightable, in the exact form of a “creatively” ordered listing, but the weights themselves would almost certainly not be if the US judicial system rules consistently.
This bypasses the entire argument of whether it is human authorship as weights themselves in bulk are just straight up non-copyrightable regardless of origin according to this reading of the law and precedent.
