alt Hacker News> I think there's no meaningful case by the letter of the law that use of training data that include GPL-licensed software in models that comprise the core component of modern LLMs doesn't obligate every producer of such models to make both the models and the software stack supporting them available under the same terms.
Why do you think "fair use" doesn't apply in this case? The prior Bartz vs Anthropic ruling laid out pretty clearly how training an AI model falls within the realm of fair use. Authors Guild vs Google and Authors Guild vs HathiTrust were both decided much earlier and both found that digitizing copyrighted works for the sake of making them searchable is sufficiently transformative to meet the standards of fair use. So what is it about GPL licensed software that you feel would make AI training on it not subject to the same copyright and fair use considerations that apply to books?

Broadly speaking, GPL is a license that has specific provisions about creating derivative software from the licensed work, and just saying "fair use" doesn't exempt you from those provisions. More specifically, an advertised use case (in fact, arguably the main one at this stage) of the most popular closed models as they're currently being used is to produce code, some of which is going to be GPL licensed. As such, the code used is part of the functionality of the program. The fact that this program was produced from the source code used by a machine learning algorithm rather than some other method doesn't change this fundamental fact.
The current supreme court may think that machine learning is some sort of magic exception, but they also seem to believe whatever oligarchs will bribe them to believe. Again, I doubt the law will be enforced as written, but that has more to do with corruption than any meaningful legal theory. Arguments against this claim seem to ignore that courts have already ruled these systems to not have intellectual property rights of their own, and the argument for fair use seems to rely pretty heavily on some handwavey anthropomorphization of the models.

The poster doesn't like it, so it's different. Most of the "legal analysis" and "foregone conclusions" in these types of discussions are vibes dressed up as objective declarations.
Bartz v Anthropic explicitly held ruling on fair use. It is not precedent, here.
