OpenAI brings together legal arguments on AI training

On October 30, 2026, OpenAI published excerpts from court filings supporting the application of fair use to training AI on copyrighted works. The collection presents arguments by the authors, not a court decision. The full filings are available in the court docket, according to the post. OpenAI

The purpose of training and its effects

AI Progress argues that training serves a different purpose from the original works, does not give the public access that would substitute for them, and does not cause the market harm recognized by the Copyright Act. On these grounds, it maintains that training is a transformative use protected by fair use. The collection also includes contributions from Authors Alliance, Electronic Frontier Foundation, and Public Knowledge. OpenAI

Consequences for people who use AI

The American Council of the Blind, Association of Research Libraries, American Library Association, Consumer Technology Association, and Business Software Alliance jointly argue that restricting training protected by fair use would affect developers as well as users and institutions. They cite medical research, education, accessibility, agriculture, independent creation, software, and law as areas where many people rely on systems developed by third parties. OpenAI
