The model weights are the result of an automated process, by definition, and thus not protected by copyright.

In my unusually well-informed on copyright but not a lawyer opinion, without any new legislation on the subject, I suspect that the most likely scenario for intellectual property rights surrounding AI is that using other people's works for training probably falls under fair use, since it's extremely transformative (an AI that makes text and a textual work are very different things) and it's extremely difficult to argue that the AI, as it exists today, directly impacts the value of the original work.

The list of what traing data to use is probably protected by copyright if hand-picked, otherwise just whatever web-crawler they wrote to gather it.

The AI models, as in, the inference and training applications are protected by copyright, like any other application.

The architecture of a particular AI model can be protected by patents.

The weights, as the result of an automated process, are probably not protected by copyright.

Object code is the result of an automated process and is covered by the copyright on the source code.

Compilations are covered by copyright separate from that of the individual works, and it is arguable that a training set would be covered by a compilation copyright, and the result of applying an automated training processs to it would remain covered by that copyright.
