If the resulting code looks like copyrighted code, then you’re in trouble. If it doesn’t look like copyrighted code then you’re fine.

^^ Very much this.

Loads of people are treating the process of AI creating works as either violating copyright or not. But that is not how copyright works. It applies to the output of a process not the process itself. If someone ends up writing something that happens to be a copy of something they read before - that is a violation of copy write laws. If someone uses various works and creates something new and unique then that is not a violation. It does not - at this point in time at least - matter if that someone is a real person or an AI.

AI can both violate copy write on one work and not on another. Each case is independent and would need to be legislated differently. But AI can produce so much content so quickly that it creates a real problem for a case by case analysis of copy write infringement. So it is quite likely the laws will need to change to account for this and will likely need to treat AI works differently from human created works. Which is a very hard thing to actually deal with.

Now, one could also argue the model itself is a violation of copyright. But that IMO is a stretch - a model is nothing like the original work and the copyright law also does not cover this case. It would need to be taken to court to really decide on if this is allowed or not.

Personally I don't think the conversation should be on what the laws currently allow - they were not designed for this. But instead what the laws should allow. So we can steer the conversation towards a better future. Lots of artists are expressing their distaste for AI models to be trained on their works - if enough people do this laws can be crafted to backup this view.
