NVIDIA has been sued by three authors who claim the company is using their books without permission to train its NeMo AI platform, Reuters reported.

Three writers – Brian Keene, Abdi Nazemian and Stewart O’Nan share that parts of their works have been implemented in 196,640 books. All the data from these books was used to train NeMo to recreate written language.

After some time, the database of NeMo training books was removed due to reports that it was affected and violated copyrights.

The authors filed a class-action lawsuit against the organization in federal court in San Francisco on Friday. They report that NVIDIA’s removal of the book database makes it clear to them that the company acknowledges that using these resources infringes their copyright.

The writers are looking to see if there are other authors in the US whose copyrights have been infringed and affected in training NeMo to accurately recreate language models over the past 3 years.

In their class-action lawsuit, the authors state that the company uses the following works: Keene’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 refused to comment on the case on Sunday. This case puts her in the middle of litigation brought by various writers who want their works protected from being used by an AI that creates new content based on their work.
