Tesla is developing a 'bunkerlike' data center at its headquarters in Austin, Texas, The Information reports.

The electric car company already operates a Dojo supercomputer in San Jose, California, and recently moved into an NTT Global Data Centers facility in Sacramento that was vacated by Elon Musk-owned Twitter/X.

The Dojo supercomputer uses the custom Dojo D1 chip architecture designed for training self-driving vehicle systems.

In July, Musk claimed that the company would spend "well over $1 billion on Dojo," but did not clarify how much of that was for hardware and how much was for infrastructure. It also includes research and development costs.

When Tesla began installing Dojo last year, it claimed it created a fully custom-designed cooling distribution unit to support densities of more than 200kW per cabinet. Those cabinets, it said, were also custom.

At the time, the company said that Dojo would feature around 3,000 custom D1 chips, for a total of 1.1 exaflops (BF16/CFP8) of performance.

Alongside Dojo, Tesla is known to have a significant GPU footprint - as of 2021 it had 10,000 GPUs across three HPC clusters - with Musk in July saying that that number is only set to grow. "We’ll actually take Nvidia hardware as fast as Nvidia will deliver it to us," he said. "Tremendous respect for Jensen [Huang, CEO and founder] and Nvidia. They’ve done an incredible job.

"And frankly, I don’t know, if they could deliver us enough GPUs, we might not need Dojo - but they can’t."

Details about the new data center are not known. An Austin-based job listing earlier this year called for "first-of-its-kind data centers."

Musk previously said that he might offer Dojo to other businesses as a cloud resource, but has yet to do so.
