OpenAI and its biggest sponsor, Microsoft, are facing several lawsuits that are they accuse of using other people’s copyrighted works to train large language models (LLM). And it looks like we may be seeing more lawsuits against both companies in the future. It is “impossible to train today’s cutting-edge artificial intelligence models without using copyrighted material,” OpenAI wrote in a document submitted to the UK House of Commons Communications and Digital Affairs Committee.

According to OpenAI, the reason is the fact that today, copyright “covers virtually all kinds of human expression—including blog posts, photographs, forum posts, software code snippets, and government documents“. The company added that “limiting the training data to books and drawings that are out of copyright and created more than a century ago might be an interesting experiment, but it would not help create artificial intelligence systems that meet the needs of today’s citizens.”

Some of the lawsuits filed against OpenAI and Microsoft allege that the companies refuse to pay authors for their work, and at the same time they are building a billion dollar industry and making a huge financial profit from copyrighted material. The latest lawsuit, filed by a pair of writers, claims that the companies could have offered authors a share of the profits, for example, but instead “chose to steal.”

OpenAI has not commented on these specific lawsuits, but has provided a response to a complaint by The New York Times accusing it of using its news articles without permission. The company says the diary is not telling the whole truth. OpenAI has reportedly been discussing a partnership with The New York Times for some time, which would give her access to this publication’s coverage. Neither party stated why the agreement was not reached in the end.
