Elon Musk’s artificial intelligence startup, xAI, has launched the most powerful iteration of its Large Language Model (LLM), Grok-3. 

Grok-3’s was formally announced in a livestream on social media platform X.

Grok-3:

  • As per Elon Musk during xAI’s livestream, “Grok 3 is an order of magnitude more capable than Grok 2.”
  • Grok-3 is the product of xAI’s Colossus supercluster, which is currently comprised of 200,000 GPUs.
  • xAI noted that Colossus is the world’s largest fully connected H100 supercluster of its kind.
  • What is quite amazing is that xAI doubled the size of Colossus from 100,000 GPUs to 200,000 in just 92 days.
  • For context, it took xAI 122 days to get the first 100k GPUs running for its Colossus supercluster.
  • Grok-3 completed pre-training in early January. It involved over 10x more training than its predecessor, Grok-2.
  • xAI also introduced a smart search engine with Grok-3, called DeepSearch.

Grok-3 potential:

  • Grok-3 is currently being offered to social media platform X’s Premium+ subscribers.
  • xAI has also launched a new subscription, SuperGrok, for the LLM’s mobile app and Grok.com website.
  • Initial benchmark tests for Grok-3 have been very optimistic, with the new AI outperforming other large language models in its category.
  • Grok-3 also reached a score of 1400 on Chatbot Arena, the first model to achieve such a rating. 

xAI speed:

  • During the xAI Engineering Open House event in San Francisco last year, Elon Musk shared a quote that stood out to the event’s attendees.
  • During his talk, Musk reportedly emphasized that speed in innovation is of the utmost importance.
  • “No SR-71 Blackbird was ever shot down and it only had one strategy: to accelerate,” Musk wrote.
  • Ultimately, it is difficult not to be impressed with xAI’s speed. After all, it has only been 17 months since the company started kicking off its very first model.
  • xAI also started its operations several years behind industry leaders such as OpenAI and Google.

Tesla expands Robotaxi program in Austin to new riders

Tesla has been expanding both the rider group and the geofence in Austin slowly, making sure to prioritize safety and avoid any major events with the early rollout.

Tesla is expanding its Robotaxi program in Austin, Texas, as several people have received invitations to participate and take rides.

Tesla first launched the Robotaxi platform on June 22. It invited a handful of people to participate in the first-ever public rides. We were lucky enough to get an invitation, and our permissions have been expanded in the Bay Area pilot program as well.

The group was small and consisted of big names in the Tesla community. It expanded and is continuing to offer these exclusive invitations to notable members of the Tesla community.

There have been fewer than five subsequent invitations after the first group’s were sent in late June:

Tesla’s new Robotaxi geofence shape is an FU by Elon Musk to the competition

“We are being very cautious. We do not want to take any chances, so we are going to go cautiously. But the service areas and the number of vehicles in operation will increase at a hyper-exponential rate,” CEO Elon Musk said during the Q2 Earnings Call.

Eventually, the Robotaxi platform will not require an invite, and it will operate without geofences. Musk believes Tesla can get there within three or six months, and plans to have at least half of the U.S. population with access to a Robotaxi by the end of the year:

“I think we will probably have autonomous ride-hailing in probably half the population of the U.S. by the end of the year. That’s at least our goal, subject to regulatory approvals. I think we will technically be able to do it. Assuming we have regulatory approvals, it’s probably addressing half the population of the U.S. by the end of the year.”

Tesla plans to have regulatory approval in Nevada, Arizona, and Florida sooner than in other states.

Tesla makes major change at Supercharger Diner amid epic demand

To ensure that menu items are both available in plentiful quantities and fresh, the menu could feature some seasonal options moving forward.

Tesla has made a major change at its Supercharger Diner in Los Angeles as the location is experiencing epic amounts of demand after launch.

The Supercharger Diner was an idea of CEO Elon Musk’s way back in 2018. It took some time to come to fruition, but it has finally opened, serving its first customers in July.

Tesla Supercharger Diner officially opens: menu, prices, features, and more

Upon its launch, people lined up around the block to give the restaurant a try. There were some who admitted to waiting 13 hours for the doors to open, which finally did at 4:20 p.m. local time.

If you know anything about Tesla, you know that the time fits the bill for the company.

Tesla Cybertruck leftovers are the main course at the Supercharger Diner

Nevertheless, it has basically been a non-stop operation since its grand opening. It’s already available to serve customers 24 hours a day and 7 days a week. These hours, along with the long-awaited grand opening, have brought tens of thousands of customers in the first few weeks.

As a result, the Diner’s chef, Eric Greenspan, revealed there will be some things that will no longer be on the menu as it handles “unprecedented demand.”

He told Eater the menu would be “forever evolving.” It has, as a result, now been void of the following menu items:

  • Market Salad
  • Club Sandwich
  • Hashbrown Bites
  • Biscuits and Red Gravy
  • Chocolate Chip Cookies
  • Vegan Patty option for Burger
  • Waffles are now only served in the morning, instead of all day
  • Soft serve will return this week. It’s provided by a local farm, which couldn’t handle the demand
  • Reimagined fountain drinks

Tesla focused on sourcing a vast majority of the food from local sources. This is likely why it has been forced to scale back much of its menu for the time being. When restaurants source their food and beverages locally, their menus change frequently.

To ensure that menu items are both available in plentiful quantities and fresh, the menu could feature some seasonal options moving forward.

The real reason the Air Force wants Tesla Cybertrucks will shock you

Tesla Cybertruck was the ideal pick for upcoming munitions testing by the U.S. Special Operations Command (USSOCOM).

It was recently revealed in U.S. government filings made public that the Tesla Cybertruck was sought out by the Air Force for munitions training and testing, and the reason why the vehicle was specifically chosen will shock you.

Last night, we reported that the U.S. Air Force was looking to buy a fleet of 33 total vehicles for its Special Operations Command (USSOCOM)’s Standoff Precision Guided Munition (SOPGM) training and tests. Documents filed showed that two Cybertrucks were requested.

While many of these cars are used for simple target practice and are intended to be disposed, the Cybertruck seems to be a bit more of a challenge for the heavy artillery that will be used on it. Some documents that revealed the plans went into detail about why the Cybertruck was specifically chosen.

Tesla Cybertruck blasted by another firearm to prove unbelievable strength

One filing said that the Cybertruck is simply more capable than typical vehicles. The government believes Cybertrucks would be used by enemy forces because of their proven durability against gunfire:

“In the operating theatre, it is likely [that] the type of vehicles used by the enemy may transition to Tesla Cyber trucks as they have been found not to receive the normal extent of damage expected upon major impact. Testing needs to mirror real-world situations.”

We’ve already seen this on one occasion, as Chechen warlord Ramzan Kadyrov managed to install a turret on the back of one of the all-electric pickups last year. Kadyrov claimed Musk “remotely disconnected” the Cybertruck.

Tesla Cybertruck with turret ‘disabled by Elon Musk,’ Chechen warlord says

In an effort to find comparable vehicles that displayed similar characteristics to Cybertruck, the military performed market research in February to do so. However, it was unsuccessful, claiming the pickup design “sets it apart” from others:

“On 13 February 2025, market research was conducted to assess the competition for the Tesla Cybertruck by evaluating its design, materials, impact resistance, and innovative technologies. The study revealed that the Cybertruck’s aggressively angular and futuristic design, paired with its unpainted stainless steel exoskeleton, sets it apart from competitors typically using painted steel or aluminum bodies. Additionally, its 48V electrical architecture provides superior power and efficiency, a feature that rivals are only beginning to develop. Extensive internet searches and industry outreach by [redacted] found no vehicles with features comparable to those of the Cybertruck.”

It is interesting considering there are outlets and people out there who routinely mention the Cybertruck as an unreliable vehicle with a lot of quality problems. Many point to the recall from the National Highway Traffic Safety Administration (NHTSA) that aimed to solve body panels disconnecting from the pickup as proof that the car is unsafe.

However, the NHTSA’s 473 Safety Recall Report claims that just 1 percent of the potentially involved population of 46,906 Cybertrucks will be impacted by that recall.

It is apparently strong and reliable enough for the military to use it as a target for munitions training.
