Dell Technologies 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 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-backed OpenAI and Alphabet's Google. Musk also co-founded OpenAI.
