Adam Schiff introduces bill amid growing legal battle over whether major AI companies have made illegal use of copyrighted works

A bill introduced in the US Congress on Tuesday intends to force artificial intelligence companies to reveal the copyrighted material they use to make their generative AI models. The legislation adds to a growing number of attempts from lawmakers, news outlets and artists to establish how AI firms use creative works like songs, visual art, books and movies to train their software–and whether those companies are illegally building their tools off copyrighted content.

The California Democratic congressman Adam Schiff introduced the bill, the Generative AI Copyright Disclosure Act, which would require that AI companies submit any copyrighted works in their training datasets to the Register of Copyrights before releasing new generative AI systems, which create text, images, music or video in response to users’ prompts. The bill would need companies to file such documents at least 30 days before publicly debuting their AI tools, or face a financial penalty. Such datasets encompass billions of lines of text and images or millions of hours of music and movies.
