If I publish a book using gpt. Openai owns the copyrights to the book ?

Lots of discussion going on these days in legal circles. General consensus seems to be that generative works should not be copyrightable. But what about hybrid works? Slippery slope...

If you’re in the US, it does not have any copyright protection, because the US Copyright Office has come down definitively saying, copyright is reserved for *human* authorship only.

Essentially, it becomes public domain/CC0.

The parts that you edit become your copyrighted work, however.

(IANAL, YMMV)
