Indeed, but it’s a much more legally dubious proposition when it comes to entire repos. A repo has more potentially creative structure for copyright to attach to. For example the class graph, or the filesystem layout are creative decisions that could potentially be protected. Current LLMs are nowhere near powerful enough to reimplement an entire repo without violating copyright.

For an individual function I can totally believe GPT4 could strip creative expression from it today. For example you could ask it to give a detailed description of a function in English, and then feed that English description back in (in a new session) and ask it to generate a code based upon the description.
