A group of authors, including Pulitzer Prize winner Michael Chabon, sued Meta Platform in San Francisco federal court on Tuesday, alleging the tech giant misappropriated their work to train llama artificial intelligence software.
Chabon, Tony-winning playwright David Henry Hwang and authors Matthew Klamm, Rachel Louise Snyder and Ayelet Waldman said in a lawsuit that Meta taught the Llama Llama large language model to respond to human text prompts with a dataset including pirated versions of their writing.
The same authors filed a similar proposed class-action lawsuit against ChatGPT creator OpenAI on Friday. The authors of the OpenAI case state that works such as books and plays are particularly valuable for AI language training as “the best examples of high-quality, long-form writing”.
A Meta spokesman declined to comment on the new lawsuit. A lawyer for the authors did not immediately respond to a request for comment.
Meta and OpenAI were sued for copyright infringement in July by a separate group of authors including comedian Sarah Silverman, part of a growing list of copyright cases against AI companies.
Meta published a list of datasets used to train the first version of the Llama model, which they released in February.
The company did not disclose training data for its latest version, Llama 2.
Llama 2, the first major language model made publicly available by Meta for commercial use, is free to use for companies with fewer than 700 million monthly active users.
