NEW YORK (Reuters) -The New York Times sued OpenAI and Microsoft on Wednesday, accusing them of using millions of the newspaper's articles without permission to help train artificial intelligence technologies.

The Times said it is the first major U.S. media organization to sue OpenAI and Microsoft, which created ChatGPT and other AI platforms, over copyright issues.

It said the defendants were trying to "free-ride on The Times’s massive investment in its journalism by using it to build substitutive products without permission or payment," according to the complaint filed in Manhattan federal court.

"There is nothing 'transformative' about using The Times's content without payment to create products that substitute for The Times and steal audiences away from it," the Times said.

OpenAI and Microsoft did not immediately respond to requests for comment.
