- Major publishers are suing Meta for copyright infringement, alleging unauthorized use of their materials to train the Llama AI model. This lawsuit, seeking monetary damages, could set a precedent for AI training data usage and potentially increase costs for AI development, creating a slight negative sentiment for Meta and the broader AI sector.

Investing.com -- Five major publishing houses filed a lawsuit against Meta Platforms on Tuesday in Manhattan federal court, claiming the company used their copyrighted materials without authorization to train its Llama artificial intelligence model.
Elsevier, Cengage, Hachette, Macmillan and McGraw Hill, along with author Scott Turow, filed the proposed class action complaint alleging Meta copied millions of their works to train its large language models.
The publishers claim Meta used materials ranging from textbooks and scientific articles to novels, including "The Fifth Season" by N.K. Jemisin and "The Wild Robot" by Peter Brown, for AI training purposes.
Maria Pallante, president of the Association of American Publishers, said in a statement that Meta’s actions do not constitute public progress and that AI development should not prioritize unauthorized sources over legitimate scholarship and creative works.
The plaintiffs are seeking court approval to represent a broader class of copyright owners and are requesting monetary damages. The specific amount of damages has not been disclosed.
Anthropic, which is backed by Amazon and Google, settled a similar class-action lawsuit last year, agreeing to pay a group of authors $1.5 billion.
