SACRAMENTO, United States, Sept. 22 (Xinhua) -- Nvidia will invest up to 100 billion U.S. dollars in OpenAI data center buildout, Nvidia founder and CEO Jensen Huang said Monday.

Nvidia and OpenAI unveiled a letter of intent for what the two companies called a landmark buildout of artificial intelligence computing, pairing at least 10 gigawatts of Nvidia systems with a planned investment of up to 100 billion dollars from Nvidia, according to their announcements.

"This is the biggest AI infrastructure project in history," Huang said, adding the partnership was about moving AI "from the labs into the world," according to an interview-style post on Nvidia's corporate blog.

OpenAI CEO Sam Altman said "there's no partner but Nvidia that can do this at this kind of scale, at this kind of speed," and called the infrastructure "the fuel that we need to drive improvement," the blog reported.

The firms said the first gigawatt is targeted for the second half of 2026 on Nvidia's Vera Rubin platform, and the partnership will use millions of Nvidia GPUs to train and run OpenAI's next generation of models.

OpenAI said it now serves more than 700 million weekly active users, underscoring the need to scale capacity as new models roll out. ■
