How the e-mails work

Uses the search, kind and company you set above (not the month or sort). As we post means within about 15 minutes of a new item; digests go out in the morning, U.S. Central time, weekly on Mondays, and only when something new matches. Updates start right away, and every e-mail has a one-click unsubscribe. Someone you invite gets one e-mail asking them to accept, and nothing more unless they do; we don’t tell them who invited them. Privacy.

Meta's answer to textbook authors admits torrenting LibGen and Anna's Archive data, and that some data was uploaded

In its answer to the textbook authors' class complaint, Meta admits it downloaded parts of datasets by direct download and by torrenting, and that the data included material from Books3, LibGen, Z-Library and Sci-Hub, portions of which were used to train some Llama models. It admits torrenting data from Anna's Archive, including Z-Library and LibGen portions, and that some data was uploaded while it torrented. Meta says LibGen data downloaded around October 2022 was not used to train Llama 1, but admits LibGen data it downloaded in 2023 was used to develop and train certain later Llama models. It also admits some models were trained on data included in Books3, that its training data included textbook data in some circumstances, and that it did not license the works the plaintiffs assert. Meta denies the remaining allegations and pleads twelve affirmative defenses, starting with fair use.

What the labels mean

Every item says what kind of source it rests on. A court ruling or order is the court's own statement. A company filing is what a defendant says about itself. A government filing is a statement by a government agency that is not a party to the case, such as a statement of interest; it is the government's position, not a ruling. An allegation is what a complaint or motion claims and has not been decided. Reported means press reporting we have not confirmed from the primary document. Summaries are our own; follow the links for the source.

This page is general information, not legal advice. An allegation is not a finding. Whether any of this matters for a particular work or claim is a question for a lawyer.
