I’ve yet to read an actual argument defending commercial LLM’s as fair use based on existing (edit:legal) criteria.

It seems like a pretty reasonable argument and easy enough to make. A human with a great memory could probably recreate some absurd % of Harry Potter after reading it, there are some very unusual minds out there. It is clear that if they read Harry Potter and being capable of reproducing it on demand as a party trick that would be fair use. So the LLM should also be fair use since it is using a mechanism similar enou…

> A human with a great memory

This kind of argument keeps popping up usually to justify why training LLMs on protected material is fair, and why their output is fair. It's always used in a super selective way, never accounting for confounding factors, just because superficially it sort of supports that idea.

Exceptional humans are exceptional, rare. When they learn, or create something new based on prior knowledge, or just reproduce the original they do it with human limitations and timescales. Laws account for these limitations but still draw lines for when some of this behavior is not permitted.

The law didn't account for a computer "software" that can ingest the entirety of human creation that no human could ever do, then reproduce the original or create an endless number of variations in a blink of an eye.

No, assuming that just because it was in the training data it must be memorized is hare brained. LLMs have limited capacity to memorize, under ~4 bits per parameter[1][2], and are trained on terabytes of data. It's physically impossible for them to memorize everything they're trained on. The model memorized chunks of Harry Potter not just because it was directly trained on the whole book, which the article also allud…

No, we know it because it was established in court from Meta internal communications. https://www.theguardian.com/technology/2025/jan/10/mark-zuck...

I'm confused. Nowhere in my post have I said that they didn't?

> is clear that if they read Harry Potter and reproduce it on demand as a party trick that would be fair use. Actually no that could be copyright infringement. Badly signing a recent pop song in public also qualifies as copyright infringement. Public performances count as copying here.

> Badly signing a recent pop song in public also qualifies as copyright infringement For commercial purposes only. If someone sells a recreation of the Harry Potter book, it’s illegal regardless whether it was by memory, directly copying the book, or using an LLM. It’s the act of broadcasting it that’s infringing on copyright, not the content itself.

There’s a bunch of nuance here.

But just for clarification, selling a recreation isn’t required for copyright infringement. The copying itself can be problematic so you can’t defend yourself by saying you haven’t yet sold any of the 10,000 copies you just printed. There are some exceptions that allow you to make copies for specific purposes, skip protection on a portable CD player for example, but that doesn’t apply to the 10k copies situation.

Repeating half of the book verbatim is not nearly the same as repeating a line.

If you prompt the LLM to output a book verbatim, then you violated the copyright, not the LLM. Just like if you take a book to a copier and make a copy of it, you are violating the copyright, not Xerox.

What if the printer had a button that printed a copy of the book on demand?

It's not clear that it's incorrect.

I’ve yet to read an actual argument defending commercial LLM’s as fair use based on existing (edit:legal) criteria.

Based upon legal decisions in the past there is a clear argument that the distinction for fair use is whether a work is substantially different to another. You are allowed to write a book containg information you learned about from another book. There is threshold in academia regarding plagiarism that stands apart from the legal standing. The measure that was used in Gyles v Wilcox was if the new work could substitute for the old. Lord Hardwicke had the wisdom to defer to experts in the field as to what the standard should be for accepting something as meaningfully changed.

Recent decisions such as Andy Warhol Foundation for the Visual Arts, Inc. v. Goldsmith have walked a fine line with this. I feel like the supreme court got this one wrong because the work is far more notable as a Warhol than as a copy of a photograph, perhaps that substitution rule should be a two way street. If the original work cannot substitute for the copy, then clearly the copy must be transformative.

LLMs generating works verbatim might be an infringement of copyright (probably not), distributing those verbatim works without a licence certainly would be. In either case, it is probably considered a failure of the model, Open AI have certainly said that such reproductions shouldn't happen and they consider it a failure mode when it does. I haven't seen similar statements from other model producers, but it would not surprise me if this were the standard sentiment.

Humans looking at works and producing things in a similar style is allowed, indeed this is precisely what art movements are. The same transformative threshold applies. If you draw a cartoon mouse, that's ok, but if people look at it and go "It's Mickey mouse" then it's not. If it's Mickey to tiki Tu meke, it clearly is Mickey but it is also clearly transformative.

Models themselves are very clearly transformative. Copyright itself was conceived at a time when generated content was not considered possible so the notion of the output of a transformative work being a non transformative derivative of something else was never legally evaluated.

Copyright notices in books make it absolutely clear - you are not allowed to acquire a text by copying it without authorisation.

If you photocopy a book you haven't paid for, you've infringed copyright. If you scan it, you've infringed copyright. If you OCR the scan, you've infringed copyright.

There's legal precedent in going after torrenters and z-lib etc.

So when Zuckerberg told the Meta team to do the same, he was on the wrong side of precedent.

Arguing otherwise is literally arguing that huge corporations are somehow above laws that apply to normal people.

Obviously some people do actually believe this. Especially the people who own and work for huge corporations.

But IMO it's far more dangerous culturally and politically than copyright law is.

Very clear and precise line of thoughts. Thank you for that post.

I think you may have something with that line of reasoning.

The threshold for transformative for fictional works is fairly high unfortunately. Fan fiction and reasonably distinct works with excessive inspiration are both copyright infringing. https://en.wikipedia.org/wiki/Tanya_Grotter

> Models themselves are very clearly transformative.

A near word for word copy of large sections of a work seems nowhere near that threshold. An MP3 isn’t even close to a 1:1 copy of a piece of music but the inherent differences are irrelevant, a neural network containing and allowing the extraction of information looks a lot like lossy compression.

Models could easily be transformative, but the justification needs to go beyond well obviously they are.

Copyright doesn't "produce a cultural hellscape." That's just nonsense. Capitalism does because it has editorial control over narratives and their marketing and distribution.

Those are completely different phenomena. Removing copyright will not suddenly open the floodgates of creativity because anyone can already create anything.

But - and this is the key point - most work is me-too derivative anyway. See for example the flood of magic school novels which were clearly loosely derivative of Harry Potter.

Same with me-too novels in romantasy. Dystopian fiction. Graphic novels. Painted art. Music.

It's all hugely derivative, with most people making work that is clearly and directly derivative of other work.

Copyright doesn't stop this, because as a minimum requirement for creative work, it forces it to be different enough.

You can't directly copy Harry Potter, but if you create your own magic school story with some similar-ish but different-enough characters and add dragons or something you're fine.

In fact under capitalism it is much harder to sell original work than to sell derivative work. Capitalism enforces exactly this kind of me-too creative staleness, because different-enough work based on an original success is less of a risk than completely original work.

Copyright is - ironically - one of the few positive factors that makes originality worthwhile. You still have to take the risk, but if the risk succeeds it provides some rewards and protections against direct literal plagiarism and copying that wouldn't exist without it.

For this part in particular:

> The amount and substantiality of the portion used in relation to the copyrighted work as a whole; (42% is considered a huge fraction of a book)

For AI models as they currently exist… I'm not sure about typical or average, but Llama 3 is 15e12 tokens for all models sizes up to 409 billion parameters (~37 tokens per parameter), so a 100,000 token book (~133,000 words) is effectively contributing about 2700 parameters to the whole model.

The *average* book is condensed into a summary of that book, and of the style of that book. This is also why, when you ask a model for specific details of stuff in the training corpus, what you get back *usually* normally only sound about right rather than being an actual quote, and why LLMs need to have access to a search engine to give exact quotes — the exceptions are things that been quoted many many times like the US constitution or, by the look of things from this article, widely pirated books where there's a lot of copies.

Mass piracy leading to such infringement is still bad, but I think the reasons why matter: Given Meta is accused of mass piracy to get the training set for Llama, I think they're as guilty as can be, but if this had been "we indexed the open internet, pirate copies were accidental", this would be at least a mitigation.

(There's also an argument for "your writing is actually very predictable"; I've not read the HP books myself, though (1) I'm told the later ones got thicker due to repeating exposition of the previous books, and (2) a long-running serialised story I read during the pandemic, The Deathworlders, became very predictable towards the end, so I know it can happen).

Conversely, for this part:

> The effect of the use upon the potential market for or value of the copyrighted work. (Best argument but as it’s minimal as a piece of entertainment. Not so as a cultural icon. Someone writing a book report or fan fiction may be less likely to buy a copy. )

The current uses alone should make it clear that the effect on the potential market is catastrophic, and not just for existing works but also for not-yet-written ones.

People are using them to write blogs (directly from the LLM, not a human who merely used one as a copy-editor), and to generate podcasts (some have their own TTS, but that's easy anyway). My experiments suggest current models are still too flawed to be worth listening to them over e.g. the opinion of a complete stranger who insists they've "done their own research": https://github.com/BenWheatley/Timeline-of-the-near-future

LLMs are not yet good enough to write books, but I have tried using them to write short stories to keep track of capabilities, and o1 is already better than similar short stories on Reddit (not "good", just "better"): https://github.com/BenWheatley/Studies-of-AI/blob/main/Story...

But things do change, and I fully expect the output of various future models (not necessarily Transformer based) to increase the fraction of humans whose writings they surpass. I'm not sure what counts as "professional writer", but the U.S. Bureau of Labor Statistics says there's 150,000 "Writers and Authors"* out of a total population of about 340 million, so when AI is around the level of the best 0.04% of the population then it will start cutting into such jobs.

On the basis that current models seem (to me) to write software at about the level of a recent graduate, and with the potentially incorrect projection that this is representative across domains, and there are about 1.7 million software developers and 100k new software developer graduates each year, LLMs today would be be around the 100k worst of the 1.7 million best out of 340 million people — i.e. all software developers are the top 0.5% of the population, LLMs are on-par with the bottom 0.03 of that. (This says nothing much about how soon the models will improve).

But of course, some of that copyrighted content is about software development, and we're having conversations here on HN about the trouble fresh graduates are having and if this is more down to AI, the change of US R&D taxation rules (unlikely IMO, I'm in Germany and I think the same is happening here), or the global economy moving away from near-zero interest rates.
