Meta is on trial, facing a class action lawsuit from major book publishers and authors who claim that training its Llama AI model involved massive infringements of copyrighted materials.

The suit alleges that Meta knowingly used pirated content, including works from notorious sites like LibGen and Sci-Hub, to train its language models. The publishers argue that this practice has resulted in verbatim reproductions of their work within the AI's output.

Previous legal battles have shown mixed results: a federal judge ruled against Meta when sued by authors over the use of copyrighted material from legally purchased books but noted that his decision did not imply legality for pirated works. Meanwhile, another company, Anthropic, faced similar charges and agreed to pay $1.5 billion as part of a class action settlement.

Meta’s spokesperson, Dave Arnold, countered with the argument that AI training on copyrighted material can qualify as fair use in certain circumstances, but the ongoing legal battles highlight an increasingly complex landscape for innovation and copyright law.
