The lawsuit didn't find anything, Anthropic claimed this as part of the settlement. Companies settle without admission of wrongdoing all the time, to the extent that it can be bargained for.

They stated it in court in their papers for summary judgment on the issue of fair use. My gosh! To pretend like you know what you're talking about but missing that detail?

The judge's ruling from earlier certainly seemed to me to suggest that the training was fair use.

Obviously, that's not part of the current settlement. I'm no expert on this, so I don't know the extent to which the earlier ruling applies.

If I'm reading this right yes the training was fair use, but I was responding (unclearly) to the claim that the pirated books weren't used to train commercially released LLMs. The judge complained that it wasn't clear what was actually used, from the June order https://fingfx.thomsonreuters.com/gfx/legaldocs/jnvwbgqlzpw/... [pdf]:

> Notably, in its motion, Anthropic argues that pirating initial copies of Authors’ books and millions of other books was justified because all those copies were at least reasonably necessary for training LLMs — and yet Anthropic has resisted putting into the record what copies or even sets of copies were in fact used for training LLMs.

> We know that Anthropic has more information about what it in fact copied for training LLMs (or not). Anthropic earlier produced a spreadsheet that showed the composition of various data mixes used for training various LLMs — yet it clawed back that spreadsheet in April. A discovery dispute regarding that spreadsheet remains pending.

Thanks for this info. I was looking for which pirated books were used for which model.

Ethically speaking, if Anthropic (a) did later purchase every book it pirated or (b) compensated every author whose book was pirated, would it absolve an illegally trained model of its "sins"?

To me, the taint still remains. Which is a shame, because it's considered the best coding model so far.

No, it part because it removes agency from the authors/rightsholders. Maybe they don't want to sell Anthropic their books, maybe they want royalties, etc.

Can authors even claim such rights though? I doubt think they even had such agency to begin with

If they're the rightsholders, they can do whatever they want with their IP, including changing licensing terms, adding contractual obligations forbidding certain types of use, forbidding sale, etc.

I feel like that would bounce hard off first sale doctrine. But what do I know.

You still have to adhere to license and copyright terms after first sale.

You can't sell a Bluray disk to a movie theater and give them the right to charge an audience to watch it in the theater later.

If rightsholders are worried about certain uses of their IP being found to be fair use, they might then change the terms of release contractually to stop or at least partially prevent training.
