United States files Statement of Interest in OpenAI lawsuits: AI training is fair use; “dilution” is “deeply flawed” theory, in the view of the United States.

The United States filed a Statement of Interest in the OpenAI copyright litigation, arguing that training large language models on copyrighted works is 'exceedingly transformative' and constitutes fair use, while dismissing the 'market dilution' theory as 'deeply flawed.' The 19-page filing, submitted in In re OpenAI Copyright Infringement Litigation before Judge Stein, asserts a national interest in a robust AI industry and cites Bartz v. Anthropic PBC and Kadrey v. Meta Platforms, Inc. to support its position.
