The Globe and Mail reports in its Monday, March 11, edition that Nvidia has been sued by three authors who said it used their copyrighted books without permission to train its NeMo artificial intelligence platform. A Reuters dispatch to The Globe reports that 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 being taken down in October "due to reported copyright infringement." A proposed class action was filed on Friday in San Francisco federal court. The authors behind the action claim that the takedown reflects Nvidia's admission of training NeMo on their dataset, thereby infringing their copyrights. They are seeking unspecified damages for people in the United States whose copyrighted works were used to train NeMo's large language models in the past three years. The New York Times and several writers have commenced lawsuits against Nvidia over generative AI, which produces 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 have included OpenAI and its partner Microsoft.
