Nvidia’s Blackwell Ultra chips, the company’s next-generation graphics processor for artificial intelligence, have been commercially deployed at CoreWeave, the companies announced on Thursday.

CoreWeave has received shipments of Dell-built shipments based around Nvidia’s GB300 NVL72 AI systems, Dell said on Thursday. It’s the first cloud provider to install systems based around Blackwell Ultra.

The Blackwell Ultra is Nvidia’s latest chip, expected to ship in volume during the rest of the year. The systems that CoreWeave is installing are liquid-cooled and include 72 Blackwell Ultra GPUs and 36 Nvidia Grace CPUs. The systems are assembled and tested in the U.S., Dell said.

CoreWeave shares rose 6% during trading on Thursday, Dell shares were up about 2% and Nvidia rose less than 2%.

The announcement is a milestone for Nvidia.

AI developers still clamor for the latest Nvidia chips, which have improvements that make them better for training and deploying models.

Nvidia said Blackwell Ultra can produce 50 times more AI content than its predecessor, Blackwell.

Investors closely watch how Nvidia manages the transition when it announces new AI chips to see if there are production issues or delays. Nvidia CFO Colette Kress said in May that Blackwell Ultra shipments would start in the current quarter.

It’s also a win for CoreWeave, a cloud provider that rents access to Nvidia GPUs to other clouds and AI developers. Although CoreWeave is smaller than the cloud services operated by Amazon, Google, and Microsoft, its ability to offer Nvidia’s latest chips first give it a way to differentiate itself.

CoreWeave historically has a close relationship with Nvidia, which owns a stake in the cloud provider. CoreWeave went public earlier this year, and the stock price has quadrupled since its IPO.
