A paraphrased novel is clearly a copyright violation under existing laws. If you use GPT to produce one, then you will be sued. This does not imply that the underlying model is a copyright violation. There is no case law on the copyright status of models but it is generally believed that training a model is fair use. In the human analogy: it is legal to read Harry Potter and to learn Harry Potter from memory such that a copy of it is stored within your head. But if you reproduce and publish or perform substantial parts of Harry Potter from memory you are violating copyright (subject to the various exceptions to copyright: quotation, parody, etc).
