Human authorship?

But _where_ does the copyright start? A prompt may be copyrightable if it's specific enough. And edits made by humans to the generated code are likely to be copyrightable.

But suppose we have this case, you build a web service to track sleep times using an LLM. And then I build a service to track the blood sugar data using an LLM.

The source code for them ends up 95% identical, just because there are so many ways to generate a simple CRUD app and we both used the same LLM version. And if you had looked at these two code bases 15 years ago, it would have been a clear-cut case of copyright infringement.

But clearly, this can't be the case anymore. Mere similarity of the code can't be used as an argument when LLMs are at play.
