英伟达否认用盗版书训练AI，要求法院驳回相关诉讼

Core Viewpoint - Nvidia is facing a lawsuit for allegedly using pirated books to train its AI models, which the company denies, claiming the accusations are speculative and lack substantial evidence [1][2]. Group 1: Lawsuit Details - The lawsuit, titled Nazemian v Nvidia, was initiated by a group of authors in early 2024 and is currently being heard by Judge Jon Tigar in the Northern District of California [1]. - The plaintiffs allege that Nvidia's AI tools and reference models utilized copyrighted books from sources like "shadow libraries," including Anna's Archive and Books3 [1]. - Nvidia submitted a motion on January 29, 2024, to dismiss the lawsuit, arguing that the plaintiffs failed to provide concrete evidence that their works were downloaded or used in model training [2]. Group 2: Nvidia's Defense - Nvidia contends that the plaintiffs have not met the basic requirements for a copyright infringement lawsuit, lacking specific facts about the alleged copying of their works [2]. - The company emphasizes that discussions about potential data sources do not equate to actual usage or copyright infringement, asserting that the plaintiffs' claims are based on conjecture [2][3]. - Nvidia criticizes the plaintiffs for relying heavily on statements based on "information and belief," which it argues is insufficient for establishing infringement facts at the pleading stage [2]. Group 3: Additional Allegations - The revised complaint includes new allegations regarding multiple datasets and models, which Nvidia seeks to narrow down, arguing that the plaintiffs have not explained how specific models used their works for training [3]. - Nvidia also addresses a new "indirect liability" theory in the revised complaint, asserting that the plaintiffs have not identified any third-party direct infringement, which is necessary for establishing contributory liability [4]. - The motion to dismiss is scheduled for a hearing on April 2, 2026, in the Northern District of California [4].
