The apparant loophole is between copyrighted work and copyrighted work that is also registered. But registration can occur at any time, meaning there is little practical difference. Unless you have perfect licenses for all your training data, which nobody does, you have to accept the risk of copyright suits.
You have to license content you want to use, you cant just use it for free because it's on the internet.
Netflix doesn't just start hosting shows and hope they don't get a copyright suit...
But for inference in general, I'm not sure it makes too much sense. Training data is not just about learning facts, but also (mainly?) about how language works, how people talk, etc. Which is kind of too fundamental to be attributed to, IMO. (Attribution: Humanity)
But who knows. Maybe it can be done for more fact-like stuff.
All of that and more, all at the same time.
Attribution at inference level is bound to work more-less the same way as humans attribute things during conversations: "As ${attribution} said, ${some quote}", or "I remember reading about it in ${attribution-1} - ${some statements}; ... or maybe it was in ${attribution-2}?...". Such attributions are often wrong, as people hallucinate^Wmisremember where they saw or heard something.
RAG obviously can work for this, as well as other solutions involving retrieving, finding or confirming sources. That's just like when a human actually looks up the source when citing something - and has similar caveats and costs.
Perhaps old texts in physical form, then? It'll cost a lot to digitize that, wouldn't it? And it wouldn't really be accessible to AI hobbyists. Unless the digitization is publicly funded or something.
(A big part of this is also how insanely long copyright lasts (nearly a hundred years!) that keeps most of the Internet's material from being public domain in the first place, but I won't belabour that point here.)
Edit:
Fair enough, I can see your point. "Surely it is cheaper to digitize old texts or buy a license to Google Books than to potentially lose a court case? Either OpenAI really likes risking it to save a bit of money, or they really wanted facts not contained in old texts."
And yeah, I guess that's true. I could say "but facts aren't copyrightable" (which was supported by the judge's decision from the TFA), but then that's a different debate about whether or not people should be able to own facts. Which does have some inroads (e.g. a right against being summarized because it removes the reason to read original news articles).
Other factors that help this effort of an old model + new public facing data being complete, are the idea that other forms of media like storytelling and music have already converged onto certain prevailing patters. For stories we expect a certain style of plot development and complain when its missing or not as we expect. For music most anything being listened to is lyrics no one is deeply reading into put over the same old chord progressions we’ve always had. For art there are just too few of us who are actually going out of our way to get familiar with novel art vs the vast bulk of the worlds present day artistic effort which goes towards product advertisement, which once again follows certain patterns people have been publishing in psychological journals for decades now.
In a sense we’ve already put out enough data and made enough of our world formulaic to the point where I believe we’ve set up for a perfect singularity already in terms of what can be generated for the average person who looks at a screen today. And because of that I think even a lack of any new training on such content wouldn’t hurt openai at all.
I'm not a lawyer, but I know enough to be pretty confident that that wouldn't work. The law is about intent. Coming up with "one weird trick" to work-around a potential court ruling is unlikely to impress a judge.
