if you've used any Ai in your own code authoring, copyrights may be completely out the window
several courts have ruled Ai output is not copyrightable, I am unaware of any co-authored cases
That doesn't top people producing copies though, just trying to copyright the copies.
If you only used the output of an LLM, then you don’t qualify.
But, the use of LLMs is not disqualifying. To qualify for copyright protection your work simply must have a sufficient degree of human authorship.
However this is just about protection, not infringement.
If you use an LLM to generate something and that LLM just happens to output something that another human wrote, you may be liable for copyright infringement.
