Against the company's wishes, a court unredacted information alleging that Meta used Library Genesis (LibGen), a notorious so-called shadow library of pirated books that originated in Russia, to help train its generative AI language models. Its outcome, along with those of dozens of similar cases working their way through courts in the United States, will determine whether technology companies can legally use creative works to train AI moving forward and could either entrench AI's most powerful players or derail them. Vince Chhabria, a judge for the United States District Court for the Northern District of California, ordered both Meta and the plaintiffs on Wednesday to file full versions of a batch of documents after calling Meta's approach to redacting them "preposterous," adding that, for the most part, "there is not a single thing in those briefs that should be sealed." Chhabria ruled that Meta was not pushing to redact the materials in order to protect its business interests but instead to "avoid negative publicity." The documents were originally filed late last year but remained publicly unavailable until now.
