Elon Musk’s xAI activates “most powerful AI training cluster in the world” with 100k Nvidia H100 GPUs
Elon Musk’s artificial intelligence startup, xAI, has activated its supercomputer cluster in Memphis, Tennessee, which is comprised of 100,000 Nvidia H100 GPUs. Tesla CEO Elon Musk confirmed the milestone in a post on social media platform X.
xAI had a busy weekend, with the AI startup announcing a hiring ramp on X. Musk highlighted these efforts on Monday morning, stating that xAI was looking to increase its human talent advantage. Interestingly enough, Musk also encouraged those who are interested in AI to apply to Tesla and X.
But definitely looking to increase our human talent advantage, so please apply at @xAI, as well as @Tesla and @X https://t.co/sf4hMRco9f— Elon Musk (@elonmusk) July 22, 2024
Musk then mentioned that a collaboration between teams from xAI, X, and Nvidia has enabled the Memphis Supercomputer cluster to start training at 4:20 a.m. local time. As per Musk, the supercomputer cluster features 100,000 Nvidia H100 GPUs, effectively making it the most powerful AI training cluster in the market today.
“Nice work by xAI team, X team, Nvidia team, and supporting companies getting Memphis Supercluster training started at ~4:20 a.m. local time. With 100k liquid-cooled H100s on a single RDMA fabric, it’s the most powerful AI training cluster in the world! This is a significant advantage in training the world’s most powerful AI by every metric by December this year,” Musk wrote in a post on X.

xAI’s supercomputer cluster is expected to be used to train the company’s large language model, Grok, which is currently rolled out as a feature for X Premium subscribers. Earlier this month, Musk noted in a post on X that xAI’s Grok 3 would be trained on 100,000 H100 GPUs so “it should be really something special.”
Previous reports from Memphis back in early June suggested that xAI would be building a supercomputer cluster informally dubbed the “Gigafactory of Compute” at the 785,000-square-foot former Electrolux Memphis facility. In a press release, the Greater Memphis Chamber stated that xAI’s supercomputer project represents the city’s largest capital investment by a new-to-market company in Memphis history.
xAI’s investment is substantial. As per a Benzinga report, each Nvidia H100 GPU is estimated to cost between $30,000 to $40,000. Considering that xAI is using 100,000 Nvidia H100 units, Elon Musk’s AI startup appears to have spent about $3 billion to $4 billion for the project.

Ford is charging for a basic EV feature on the Mustang Mach-E
When ordering a new Ford Mustang Mach-E, you’ll now be hit with an additional fee for one basic EV feature: the frunk.
Ford is charging an additional fee for a basic EV feature on its Mustang Mach-E, its most popular electric vehicle offering.
Ford has shuttered its initial Model e program, but is venturing into a more controlled and refined effort, and it is abandoning the F-150 Lightning in favor of a new pickup that is currently under design, but appears to have some favorable features.
However, ordering a new Mustang Mach-E now comes with an additional fee for one basic EV feature: the frunk.
The frunk is the front trunk, and due to the lack of a large engine in the front of an electric vehicle, OEMs are able to offer additional storage space under the hood. There’s one problem, though, and that is that companies appear to be recognizing that they can remove it for free while offering the function for a fee.

Ford is charging $495 for the frunk.
Interestingly, the frunk size varies by vehicle, but the Mustang Mach-E features a 4.7 to 4.8 cubic-foot-sized frunk, which measures approximately 9 inches deep, 26 inches wide, and 14 inches high.
When the vehicle was first released, Ford marketed the frunk as the ultimate tailgating feature, showing it off as a perfect place to store and serve cold shrimp cocktail.
Ford Mach-E frunk is perfect for chowders and chicken wings, and we’re not even joking
It appears the decision to charge for what is a simple advantage of an EV is not going over well, as even Ford loyal customers say the frunk is a “basic expectation” of an EV. Without it, it seems as if fans feel the company is nickel-and-diming its customers.
It will be pretty interesting to see the Mach-E without a frunk, and while it should not be enough to turn people away from potentially buying the vehicle, it seems the decision to add an additional charge to include one will definitely annoy some customers.

Tesla to improve one of its best features, coding shows
According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.
Tesla is looking to upgrade its Matrix Headlights, a unique and high-tech feature that is available on several of its vehicles. The headlights aim to maximize visibility for Tesla drivers while being considerate of oncoming traffic.
The Matrix Headlights Tesla offers utilize dimming of individual light pixels to ensure that visibility stays high for those behind the wheel, while also being considerate of other cars by decreasing the brightness in areas where other cars are traveling.
Here’s what they look like in action:

As you can see, the Matrix headlight system intentionally dims the area where oncoming cars would be impacted by high beams. This keeps visibility at a maximum for everyone on the road, including those who could be hit with bright lights in their eyes.
There are still a handful of complaints from owners, however, but Tesla appears to be looking to resolve these with the coming updates in a Software Version that is currently labeled 2026.2.xxx. The coding was spotted by X user BERKANT:
🚨 Tesla is quietly upgrading Matrix headlights.
Software https://t.co/pXEklQiXSq reveals a hidden feature:

This is a major step beyond current adaptive high beams.

According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.
Finally, the new system will prevent the high beams from glaring back at the driver. The system is made to dim when it recognizes oncoming cars, but not necessarily objects that could produce glaring issues back at the driver.
Tesla’s revolutionary Matrix headlights are coming to the U.S.
This upgrade is software-focused, so there will not need to be any physical changes or upgrades made to Tesla vehicles that utilize the Matrix headlights currently.

xAI’s Grok approved for Pentagon classified systems: report
Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations.
Elon Musk’s xAI has signed an agreement with the United States Department of Defense (DoD) to allow Grok to be used in classified military systems.
Previously, Anthropic’s Claude had been the only AI system approved for the most sensitive military work, but a dispute over usage safeguards has reportedly prompted the Pentagon to broaden its options, as noted in a report from Axios.
Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations.
The publication reported that xAI agreed to the Pentagon’s requirement that its technology be usable for “all lawful purposes,” a standard Anthropic has reportedly resisted due to alleged ethical restrictions tied to mass surveillance and autonomous weapons use.
Defense Secretary Pete Hegseth is scheduled to meet with Anthropic CEO Dario Amodei in what sources expect to be a tense meeting, with the publication hinting that the Pentagon could designate Anthropic a “supply chain risk” if the company does not lift its safeguards.
Axios stated that replacing Claude fully might be technically challenging even if xAI or other alternative AI systems take its place. That being said, other AI systems are already in use by the DoD.
Grok already operates in the Pentagon’s unclassified systems alongside Google’s Gemini and OpenAI’s ChatGPT. Google is reportedly close to an agreement that will result in Gemini being used for classified use, while OpenAI’s progress toward classified deployment is described as slower but still feasible.
The publication noted that the Pentagon continues talks with several AI companies as it prepares for potential changes in classified AI sourcing.
