ChatGPT developer OpenAI has signed a deal to bring news content from the Wall Street Journal, the New York Post, the Times and the Sunday Times to the artificial intelligence platform, the companies said on Wednesday. Neither party disclosed a dollar figure for the deal.

The deal will give OpenAI access to current and archived content from all of News Corp’s publications. The deal comes weeks after the AI heavyweight signed a deal with the Financial Times to license its content for the development of AI models. Earlier this year, OpenAI inked a similar contract with Axel Springer, the parent company of Business Insider and Politico.

Other publications, including the New York Times, have taken a different tack: suing OpenAI and Microsoft, the startup’s key backer, over the use of its content to train generative AI and large-language model systems.

News Corp is chaired by Lachlan Murdoch. His father, Rupert, serves as chairman emeritus stepping down as chair of News Corp and Fox News last year.

Sam Altman, the chief executive of OpenAI, said: “Our partnership with News Corp is a proud moment for journalism and technology. We greatly value News Corp’s history as a leader in reporting breaking news around the world, and are excited to enhance our users’ access to its high-quality reporting.

“Together, we are setting the foundation for a future where AI deeply respects, enhances, and upholds the standards of world-class journalism.”

“We believe a historic agreement will set new standards for veracity, for virtue and for value in the digital age,” said Robert Thomson, chief executive of News Corp. “We are delighted to have found principled partners in Sam Altman and his trusty, talented team who understand the commercial and social significance of journalists and journalism.”
