In a landmark case, the Authors Guild and several author plaintiffs have initiated legal action against OpenAI, alleging significant copyright infringement related to the training of its large language models (LLMs) such as ChatGPT. The lawsuit, filed in September 2023, accuses OpenAI of unlawfully copying and ingesting copyrighted books to train its models without obtaining permission from the authors.

Background of the Case

OpenAI began as a non-profit in 2015, evolving into a for-profit entity in 2019 and securing a staggering $13 billion investment from Microsoft. With the launch of ChatGPT in November 2022, OpenAI quickly amassed a user base of 100 million monthly active users within just three months. The training datasets used by OpenAI, referred to as "Books1" and "Books2," are believed to have included content from pirate book repositories such as Library Genesis (LibGen), Z-Library, and Bibliotik. OpenAI has acknowledged utilizing "large, publicly available datasets that include copyrighted works," suggesting that avoiding copyrighted material could severely compromise the quality of their models.

Authors’ Claims of Injury

The plaintiffs argue they suffered multiple injuries from OpenAI's unauthorized use of their works. These injuries include:

  • Unauthorized reproduction of their copyrighted books

  • Creation of derivative works without consent

  • Loss of potential licensing opportunities

  • Market displacement due to AI-generated content

  • Decreased income from writing-related activities

  • Unauthorized use of their creative expression in training AI models

  • The risk of AI-generated impersonation of their writing styles

Damages

The authors assert that they have incurred significant financial and commercial damages due to OpenAI’s actions. They detail losses stemming from:

  • Lost licensing revenue from the unauthorized training use

  • Diminished market value of their original works

  • Decreased income from writing-related activities

  • Market usurpation by AI-generated content

  • Loss of control over their creative works

  • Damage to professional reputation from AI impersonation

  • Reduced opportunities in content writing markets

Legal Claims Against OpenAI

The authors have brought forward several claims, including:

  1. Direct copyright infringement under the Copyright Act

  2. Creation of unauthorized derivative works

  3. Willful copyright infringement, given OpenAI's knowledge of using copyrighted materials

  4. Commercial exploitation of copyrighted works without permission

  5. Unfair competition through unauthorized use of authors' works

The plaintiffs are seeking both monetary damages for lost licensing opportunities and a permanent injunction to prevent future unauthorized use of their works in AI training.

Discovery Disputes and Executive Communications

As the lawsuit unfolds, the Authors Guild has urged Magistrate Judge Ona T. Wang of the U.S. District Court for the Southern District of New York to compel OpenAI to produce the social media and text messages of its executives, including CEO Sam Altman and President Greg Brockman. The authors contend that the executives’ posts on X (formerly known as Twitter) indicate work-related activity, justifying the search for relevant communications. The Authors Guild has combined its lawsuit with another brought by nonfiction authors, intensifying the legal battle. OpenAI, however, has resisted disclosing the executives' direct messages, arguing that it lacks possession, custody, or control over the employees' social media accounts. The company cited California labor laws prohibiting such requests. In contrast, the plaintiffs assert that federal case law allows employers to be compelled to produce documents held by employees under their control.

Ongoing Developments

The letter submitted to Judge Wang included examples of posts from Altman, Brockman, and other executives, suggesting that their accounts should not be classified as "personal." The plaintiffs have also requested OpenAI to retrieve and review text messages from its executives, believing these communications likely contain pertinent information about the company’s practices. OpenAI responded by accusing the plaintiffs of failing to address discovery requests related to the harm they claim to have suffered from the alleged unauthorized use of their works. The company argued that this information is crucial for its fair use defense. A status conference was scheduled for October 30, where both parties are set to address these discovery issues in their proposed agendas.

Implications for the AI Industry

This lawsuit poses a significant challenge to the AI industry’s practices regarding the use of copyrighted materials for training. It may set important precedents regarding author compensation and the legal rights of creators in the face of rapidly advancing AI technologies. The outcome of this case could reshape the landscape for AI development and content creation, highlighting the critical need for clear guidelines and protections for intellectual property in the digital age.
