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.

Elon Musk hints at when Tesla could reduce Safety Monitors from Robotaxi

Tesla could be reducing Safety Monitors from Robotaxi within ‘a month or two,’ CEO Elon Musk says.

Elon Musk hinted at when Tesla could begin reducing Safety Monitors from its Robotaxis. Safety Monitors are Tesla employees who sit in the front passenger seat during the driverless rides, and are there to ensure safety for occupants during the earliest rides.

Tesla launched its Robotaxi fleet in Austin last Sunday, and after eight days, videos and reviews from those who have ridden in the driverless vehicles have shown that the suite is safe, accurate, and well coordinated. However, there have been a few hiccups, but nothing that has put anyone’s safety in danger.

A vast majority — close to all of the rides — at least according to those who have ridden in the Robotaxi, have been performed without any real need for human intervention. We reported on what was the first intervention last week, as a Safety Monitor had to step in and stop the vehicle in a strange interaction with a UPS truck.

Watch the first true Tesla Robotaxi intervention by safety monitor

The Tesla and UPS delivery truck were going for the same street parking space, and the Tesla began to turn into it. The UPS driver parallel parked into the spot, which was much smaller than his truck. It seemed to be more of an instance of human error instead of the Robotaxi making the wrong move. This is something that the driverless cars will have to deal with because humans are aggressive and sometimes make moves they should not.

The Safety Monitors have not been too active in the vehicles. After all, we’ve only seen that single instance of an intervention. There was also an issue with the sun, when the Tesla braked abnormally due to the glare, but this was an instance where the car handled the scenario and proceeded normally.

With the Robotaxi fleet operating impressively, some are wondering when Tesla will begin scaling back both the Safety Monitors and Teleoperators that it is using to ensure safety with these early rides.

CEO Elon Musk answered the inquiry by stating, “As soon as we feel it is safe to do so. Probably within a month or two.”

Musk’s response seems to confirm that there will be fewer Teleoperators and Safety Monitors in the coming months, but there will still be some within the fleet to ensure safety. Eventually, that number will get to zero.

Reaching a point where Tesla’s Robotaxi is driverless will be another significant milestone for the company and its path to fully autonomous ride-sharing.

Eventually, Tesla will roll out these capabilities to consumer-owned vehicles, offering them a path to generate revenue as their car operates autonomously and completes rides.

For now, Tesla is focusing on perfecting the area of Austin where it is currently offering driverless rides for just $4.20 to a small group of people.

A Tesla just delivered itself to a customer autonomously, Elon Musk confirms

Tesla CEO Elon Musk says the first self-delivery occurred today, one day ahead of schedule.

Tesla CEO Elon Musk has confirmed that a vehicle has, for the first time ever, delivered itself to a customer autonomously, one day ahead of the company’s original schedule.

To date, this is the first car to ever roll off a production line at a factory and transport itself to a customer for delivery.

Late last month, Musk announced that the first-ever fully autonomous delivery of a Tesla would take place on June 28. The plan was to have the car roll off the production lines at Gigafactory Texas and drive to a local customer without the assistance of anyone on board or remotely controlling the car through teleoperation.

Teslas will self-deliver to customers, Elon Musk says: here’s when

Musk said on Friday that it has officially happened:

The vehicle traveled as fast as 72 miles per hour, according to Ashok Elluswamy, Tesla’s Head of AI and Autopilot.

Musk continued on X:

“There were no people in the car at all and no remote operators in control at any point. FULLY autonomous! To the best of our knowledge, this is the first fully autonomous drive with no people in the car or remotely operating the car on a public highway.”

He said a video of the delivery would be uploaded soon.

We have seen cars autonomously transport themselves from production line to logistics lot at Gigafactory Texas, but this is a whole new level.

Tesla just recently launched its Robotaxi for the first time in Austin on Sunday. Opened to a limited number of people, the company rolled out an Early Access Riders Program, but has been expanding it to more people in recent days. These cars featured a Safety Monitor in the passenger’s seat to ensure safety.

This seems to be something Tesla would like to perform more frequently in the coming months, especially locally. Eventually, it seems that Tesla will plan to have every vehicle it manufactures self-deliver, as a hauler would transport it to local delivery centers, then the car would drive itself to the customer’s house.

This is likely a few years off, but Tesla has already completed one self-delivery, which is an incredible accomplishment.

Yesterday, I wrote about Tesla’s two big milestones that are still planned for launch before the end of Q2. This was one of them. One to go: unveiling of the affordable models.

Tesla still has two major milestones on track before end of Q2

Tesla still is on track to complete two monumental achievements as Q2 nears its end.

Tesla still has two major milestones it is on track to complete before the end of the second quarter, according to statements made by the automaker earlier this year.

With the launch of the Robotaxi platform in Austin on Sunday, Tesla has already completed perhaps its biggest milestone of 2025.

However, these are not the only things the company hopes to accomplish before we head into the latter half of the year, as there are two major things the company said it is aiming to complete before the third quarter starts next week.

Affordable Models

Tesla said earlier this year, on two separate occasions, that it is still on track to develop, build, and unveil the first affordable models that will be built on both the next-gen platform and also have aspects of the current vehicle platform.

In the Q4 2024 Earnings Call in January, the company said:

“Preparations are underway across our existing factories for the launch of new products in 2025, including more affordable models.”

The company continued:

“Plans for new vehicles, including more affordable models, remain on track for start of production in the first half of 2025. These vehicles will utilize aspects of the next generation platform as well as aspects of our current platforms and will be produced on the same manufacturing lines as our current vehicle line-up.”

Although there are only a few days left, Tesla has yet to confirm that these affordable models are delayed, so we can expect that they’ll be arriving before the quarter ends.

The company might have been hinting toward one recently at the Fremont Factory, but it is more likely that the vehicle seen was the new Model Y Performance trim:

Tesla delivers itself to customers

Back in late May, CEO Elon Musk said that the first Tesla to self-deliver would happen in June:

Tesla just launched its Robotaxi platform on Sunday, so this would be a tremendous step if it can, in fact, make this happen.

The customer would likely be extremely local to Gigafactory Texas. In the future, the company would load the vehicles onto haulers and then drive to customer homes from delivery centers, showrooms, and repair centers.

Tesla has a few days left to complete both of these tasks, and then it will report delivery figures for the second quarter next week.
