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.

Kia gains Tesla Supercharger access and issues a big apology
Kia gained Tesla Supercharger access and respect from Tesla fans in the same day.

Kia has announced that owners of the EV6, EV9, and Niro EVs have officially gained access to over 21,500 Tesla Supercharger locations in North America.
However, its announcement also contained an apology to Tesla.
First, Kia said that its three EV offerings will have access to Tesla’s expansive Supercharger Network. More than 40,000 DC fast chargers are available to Kia EV drivers, a major uptick as Tesla Supercharger access nearly doubles the number of accessible piles.
Sean Yoon, President of Kia North America and Kia America, said:
“Kia is committed to an exceptional ownership experience, and expanding the network of available DC fast chargers to our EV customers is an important component to maintaining the brand’s leadership in electrified mobility. Now, with access to the Tesla Supercharger network of DC fast chargers, our EV owners can feel even more confident in their decision to purchase or lease a fully electric Kia vehicle.”
Kia owners who have a CCS1 Charging Port will have access to an NACS adapter through dealerships. This will enable compatibility, as current inlets are not NACS, the port that Tesla utilizes.
However, Kia will eliminate the need for this adapter starting with the 2025 EV6 and 2026 EV9. These will come standard with NACS inlets.
We mentioned Kia included somewhat of an apology to Tesla, which is related to social media posts from “certain Nordic distributors,” as the company puts it:
Kia paid for a front page ad on Finland’s largest newspaper to mock Elon Musk and Tesla.
Translation: “Oh, These Days of Life. If you’re unsure about driving an american electric car, welcome to the Helsinki Exhibition Centre to admire the cars of the new age.”

Kia said in its announcement:
“Kia America is aware of marketing posts by certain Nordic distributors. These initiatives were developed entirely independently by those distributors, without direction from Kia America, Kia Europe or Kia Global. We want it to be clear that these posts do not reflect the position of Kia America, and we remain committed to clear and professional communication that reflects our values.”
The company also said that it “condemns the recent attacks that disrupt the availability of convenient and affordable charging for our customers.”

Tesla adds new child protection feature to mobile app
Tesla is rolling out within its mobile app a new feature that aims to save the lives of those forgotten in the car.

Tesla is bolstering its in-car safety system with the addition of a new feature that aims to protect children left in the vehicle, an extension of a feature it introduced with the addition of 4D radar systems.
Children are, unfortunately, victims of accidents even when a vehicle is not in motion. A report from 2024 noted that 37 children under the age of 15 die each year because they are left in cars, usually dying from heatstroke.
Tesla has made a few attempts to eliminate the possibility of this happening. Back in September, coding from Software Update 2024.32 noted that the company would be using an alert system to warn people of children left behind:
Tesla set to roll out new child safety and navigation features, coding shows
This was enabled by the use of a wave sensor within the cabin, a piece of tech Teslarati found in a filing back in 2021 with the FCC.
The entire idea behind this addition to the vehicles was to alert owners if there were passengers left in the car.
Now, Tesla is adding another level of this to its mobile app, according to a decompile of the Version 4.44.0 update, which is rolling out to customers now.
Tesla App Updates on X revealed a “Child Left Alone Detection” feature in the new app version, which has a few strings from a software perspective:
-
Cannot turn off climate when Child Left Alone Detection is active
-
Climate failed to start. Climate is unavailable when Child Left Alone Detection is active.
-
Climate controls are disabled when Child Left Alone Detection is active
-
Unable to start software update while a child is detected in your vehicle
It appears that, if the vehicle detects a child or another occupant in the car, climate controls will be disabled through the app in an attempt to maintain a proper cabin temperature. Turning the temperature up or even turning climate control off from the app will not be possible.
This is a major update to this feature as it only bolsters the safety of the occupants in the event that they are left behind. Of course, many of us might ask, “How do you leave a child in the car?”
However, it happens, as past events have shown, and this is a great way to eliminate it from happening in Tesla vehicles.

Tesla FSD ruins other intelligent driving systems for NIO Superfan influencer
“Since I drove FSD, I have been disenchanted with all the ‘driving assistance’ of domestic brands,” Lee wrote.

Tesla Full Self-Driving (FSD) has been making waves in China, with owners pushing the system to its limits on what appears to be a regular basis. Videos of Tesla drivers in China show FSD navigating the trickiest of roads, from busy city streets to narrow, unpaved paths in rural areas.
And as per an influencer and NIO superfan, FSD is ruining other driver-assist systems from other automakers in China.
FSD Ruins It For Influencer
China-based influencer and NIO superfan Andy Lee recently shared his thoughts about FSD on social media. As per Lee, Chinese intelligent driving systems are overhyped by marketing. But once he personally experienced FSD’s capabilities, he became disillusioned with the offerings of domestic carmakers.
“Since I drove FSD, I have been disenchanted with all the ‘driving assistance’ of domestic brands. I once thought that the ‘driving assistance’ of domestic brands could beat FSD in seconds, but it seems that I was wrong. Not only did they fail to outperform FSD, they were actually crushed in reverse,” Lee wrote in his post.
FSD could very well become Tesla’s moat since even cars that are equipped with the same hardware would not be able to perform similarly unless they have access to the company’s training data and software. Tesla’s fleet is ever-growing as well, which means that FSD will only get better over the years.
Unsupervised on the Horizon
Tesla is already using FSD Unsupervised for its vehicles that are produced in the Fremont Factory and Gigafactory Texas. As per Elon Musk during the Q1 2025 earnings call, he expects Tesla to be able to roll out FSD Unsupervised to consumers before the end of this year. He also highlighted that Tesla is being extremely careful with FSD Unsupervised’s rollout.
“Before the end of this year. Not necessarily — I say within the U.S., like we do want to test — at Tesla, we’re absolutely hardcore about safety. We go to great lengths to make the safest car in the world and have the lowest accidents per mile in.
“So we want to be very careful. We want autonomy to be definitively safer than manual driving. So it’s not enough that it just be as safe. It needs to be meaningfully safer than if the car’s manually driven,” Musk stated.
