The Wikimedia Foundation, the nonprofit that runs the site, signed Google as one of its first customers in 2022 and announced other agreements last year with smaller AI players like search engine Ecosia.
The new deals will help one of the world's most popular websites monetize heavy traffic from AI companies. They're paying to access Wikipedia content "at a volume and speed designed specifically for their needs," the foundation said. It did not provide financial or other details.
While AI training has sparked legal battles elsewhere over copyright and other issues, Wikipedia founder Jimmy Wales said he welcomes it.
"I'm very happy personally that AI models are training on Wikipedia data because it's human curated," Wales told The Associated Press in an interview. "I wouldn't really want to use an AI that's trained only on X, you know, like a very angry AI," Wales said, referring to billionaire Elon Musk's social media platform.
Wales said the site wants to work with AI companies, not block them. But "you should probably chip in and pay for your fair share of the cost that you're putting on us."
