Nvidia, whose chips power artificial intelligence, was sued by three authors who said it used their copyrighted books without permission to train its NeMo AI platform.

Brian Keene, Abdi Nazemian and Stewart O’Nan said their works were part of a dataset of about 196,640 books that helped train NeMo to simulate ordinary written language before they were removed in October “due to a reported violation of copyright’.

In a proposed class-action lawsuit filed Friday night in San Francisco federal court, the authors said the takedown reflects Nvidia “admitting” it trained NeMo on the data set and thereby infringed their copyright.

They are seeking unspecified damages for people in the United States whose copyrighted works helped train NeMo’s so-called large language models over the past three years.

Among the works covered in the lawsuit are Keane’s 2008 novel Ghost Walk, Nazemian’s 2019 novel Like a Love Story and O’Nan’s 2007 novella Last Night at the Lobster.

Nvidia declined to comment on Sunday. Attorneys for the authors did not immediately respond to requests Sunday for additional comment.

The case embroils Nvidia in a growing group of lawsuits from writers, as well as the New York Times, over generative AI that creates new content based on inputs such as text, images and sounds.

Nvidia touts NeMo as a fast and affordable way to adopt generative AI.

Other companies sued over the technology include OpenAI, which created the AI ​​platform ChatGPT, and its partner Microsoft.

The rise of AI has made Nvidia an investor favorite.

The Santa Clara, California-based chipmaker’s stock price has risen nearly 600% since the end of 2022, giving Nvidia a market value of nearly $2.2 trillion.

The case is Nazemian et al v. Nvidia Corp, U.S. District Court, Northern District of California, No. 24-01454.
