The Center for Investigative Reporting (CIR) filed a lawsuit against OpenAI and Microsoft for alleged copyright infringement.

The CIR accused OpenAI and Microsoft of using its published content to train their AI models, specifically ChatGPT and Copilot, without permission or compensation, thereby violating the US' Copyright Act and Digital Millennium Copyright Act and underrmining its relationship with readers and depriving it of revenue.

Analysis showed that OpenAI's training data contained over 17,000 URLs from CIR outlets Mother Jones and Reveal. The CIR is seeking statutory damages and injunctions to remove its copyrighted works from OpenAI and Microsoft's training sets. 

The lawsuit highlights how AI-generated summaries of articles threaten publishers and emphasises the importance of respecting journalistic work. 

Similar lawsuits have been filed by other news organisations against OpenAI and Microsoft, including The New York Times and Chicago Tribune.
