Content deals between artificial intelligence companies and top publishers are coming fast and furious. The latest, claimed to be the biggest, was announced on Wednesday: OpenAI reached an agreement with Rupert Murdoch’s News Corp. reported to be worth some $250 million over five years.

"The pact acknowledges that there is a premium for premium journalism,” News Corp. CEO Robert Thomson said. No terms were officially disclosed, but assuming the Wall Street Journal is not misreporting on its owner, the $250 million figure includes "compensation in the form of cash and credits for use of OpenAI technology.”

This is the latest in a flurry of partnerships announced in recent weeks. The Financial Times struck its own deal with OpenAI last month, followed by Dotdash Meredith, owner of titles such as People magazine and Investopedia, whose agreement also included some collaboration on advertising tools. Other OpenAI deals have been with the Associated Press, Axel Springer and Le Monde.
