It seems weird that there was legal culpability for downloading pirated books but not for training on them. At the very least, there is a transitive dependency between the two acts.

Other people have said that Anthropic bought the books later on, but I haven't found any official records for that. Where would I find that?

Also, does anyone know which Anthropic models were NOT trained on the pirated books. I want to avoid such models.

As far as anyone knows, no models were trained on the illegally downloaded books.

		The following document indicates otherwise. https://storage.courtlistener.com/recap/gov.uscourts.cand.43.... "Similarly, different sets or “subsets” or “parts of” or “portions” of the collections sourced from Books3, LibGen, and PiLiMi were used to train different LLMs..." Page 5 "In sum, the copies of books pirated or purchased-and-destructively-scanned were placed into a central “research library” or “generalized data area,” sets or subsets were copied again to create training copies for data mixes, the training copies were successively copied to be cleaned, tokenized, and compressed into any given trained LLM, and once trained an LLM did not output through Claude to the public any further copies." Page 7 The phrase "Finally, once Anthropic decided a copy of a pirated or scanned book in the library would not be used for training at all or ever again, Anthropic still retained that work as a “hard resource” for other uses or future uses" implies to me Anthropic excluded certain books from training, not that they excluded all the pirated books from training.
