June 19 (Reuters) - Dell Technologies ( DELL ) is

assembling half of the racks for the supercomputer that xAI is

building, billionaire Elon Musk said in a post on social media

platform X on Wednesday.

The U.S. businessman has recently told investors that his

artificial intelligence startup xAI is planning to build a

supercomputer to power the next version of its AI chatbot Grok,

according to a report by the Information in May.

Dell CEO Michael Dell also said in a separate post on X that

the company was building an "AI factory" with

artificial-intelligence heavyweight Nvidia ( NVDA ) that would

power the next version of xAI's chatbot Grok.

Training of AI models such as xAI's Grok requires tens of

thousands of power-hungry chips that are in short supply.

Earlier this year, Musk said training the Grok 2 model took

about 20,000 Nvidia H100 graphic processing units (GPUs), adding

that the Grok 3 model and beyond will require 100,000 Nvidia

H100 chips.

Musk has said he wants to get the proposed supercomputer

running by the fall of 2025, according to the Information.

Musk founded xAI last year as a challenger to Microsoft ( MSFT )

-backed OpenAI and Alphabet's Google. Musk

also co-founded OpenAI.
