OpenAI is facing a copyright lawsuit from ANI over AI training data — the implications could be huge for the industry.

While OpenAI admitted to the error, the recovered data was incomplete and unorganized, making it unusable to identify whether specific articles were used in AI training. The publishers described the incident as a significant setback in their efforts to trace how OpenAI’s models were built.

A group of fiction authors is pursuing a class action lawsuit against OpenAI over alleged copyright infringement stemming from the use of their works in training AI tools like ChatGPT.

The Intercept’s lawsuit argues that the Digital Millennium Copyright Act prevents OpenAI from stripping a story’s title or byline.
