Elon Musk’s artificial intelligence (AI) startup xAI is set to launch its first model, Grok, according to multiple posts from the Tesla CEO this week.
In a post on X on Friday, Musk announced that the xAI Grok AI assistant would be included with X Premium Plus. He also reiterated the point in an additional post on Saturday, adding that users can subscribe to the upgrade tier of the social media platform tier for $16 a month.
The software is the first product to be launched by the company since Musk started xAI in July.
The @xAI Grok AI assistant will be provided as part of 𝕏 Premium+, so I recommend signing up for that.
Just $16/month via web. https://t.co/wEEIZNjEkp

Later on Saturday, both Musk and xAI posted official announcements of the AI model, along with a page for Grok appearing on the company’s website.
Announcing Grok!
Grok is an AI modeled after the Hitchhiker’s Guide to the Galaxy, so intended to answer almost anything and, far harder, even suggest what questions to ask!
Grok is designed to answer questions with a bit of wit and has a rebellious streak, so please don’t use…

Grok will have real-time access to the X platform, which Musk and the company have said is a huge advantage when compared with other generative AI models.
On the origin of the name “Grok,” Musk called one take early Saturday morning “accurate” after another user used GPT-4 to ask about the meaning of “grok,” to which the OpenAI foundation model responded that the word originates from the 1961 novel “Stranger in a Strange Land” by Robert A. Heinlein.
The book’s use of the term, according to the AI model, refers to a Martian word “that means to understand something or someone so completely that the observer becomes a part of the observed—to merge, blend, intermarry, lose identity in group experience. It’s a deep, almost metaphysical understanding.”
The rivaling language model also detailed the modern use of the word “Grok,” which has found a place in the tech world to “suggest a profound level of comprehension of software programming, technology, or a complex subject matter.”

Musk also said that Grok would have more of a sense of humor and sarcasm than other generative language models, even sharing a few screenshots from discussions with the AI. You can see his screenshots below.

Musk also noted in a response to Whole Mars Blog that the threshold for what Grok will tell you, “if pushed, is what is available on the Internet via reasonable browser search.”
The Premium Plus tier on X comes as a range of tiers set to be offered on the platform, including two lower tiers called Basic and Basic Plus. The company also says on its support page for the tiers that pricing on Premium will start at $3 per month or $32 per year, based on localized pricing.
Although X and xAI are not the same company, it’s not abnormal for Musk’s businesses to work together. Some examples include the Boring Company’s use of Tesla vehicles in its underground loops and Musk’s previous hopes for utilizing OpenAI at Tesla.
Update 11/5/23: Added official release information from xAI.

Elon Musk shuts down Tesla ‘AMG’ division speculation: ‘Focus is autonomy’
“I think it’s best to leave that to the custom shops. Tesla’s focus is autonomous cars, building futuristic autonomous cars. We want the future to look like the future.”
														Tesla CEO Elon Musk was asked by Joe Rogan late last week whether the company would ever consider establishing an “AMG division” like Mercedes-Benz has established for powerful, race-inspired vehicles.
However, Musk turned down any talk of that, highlighting that the company is laser-focused on autonomous vehicles, seemingly hinting that any distraction from autonomy would be a detriment to the future.
Rogan drives a Tesla Model S himself, but it is not your run-of-the-mill all-electric sedan. Already outfitted with the Plaid powertrain that Tesla developed, Rogan took his vehicle to Unplugged Performance for a true performance outfitting.
The vehicle is completely overhauled with performance parts and seats. Known as the Model S-APEX, Rogan took delivery of it from Unplugged in January.
Rogan asked Musk on Friday during his most recent appearance on the Joe Rogan Experience podcast whether Tesla would ever establish an “AMG division” that would focus on catering Teslas to performance-based standards.

Tesla fans have said for years that the company should consider acquiring Unplugged Performance and its Upfit Tesla division, which recently outfitted the Las Vegas Metropolitan Police Department’s fleet of Cybertruck cruisers.
However, it seems Tesla will keep things separate. Musk is primarily focused on autonomy, which will drive the technology forward and drive shareholder growth. Something like an outfitter for performance would be a cool thing for the owners who have the interest and the money.
It’s not a tremendous revenue driver or anything that would contribute to the financial state of the company. Mercedes-Benz, for example, is more accessible for consumers as it sold over 140,000 units from its AMG brand in 2024.

It helps with driving revenue higher by as much as 15 percent compared to similar models that are not AMGs. However, would Tesla see this much of a benefit? Likely not, because the Performance trim already caters to many owners.

Tesla Cybertruck fleet takes over at SpaceX’s Starbase
Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.
														Tesla Cybertrucks have taken over at SpaceX’s Starbase facility in Texas, as hundreds of the all-electric pickup trucks were spotted late last week rounding out a massive fleet of vehicles.
The Cybertruck fleet is geared toward replacing gas vehicles that are used at Starbase for everyday operations. The only surprise about this is that it was not done sooner:

Deliveries have been going on for a few weeks, as Cybertrucks have made their way across the state of Texas from Austin to Starbase so they could be included in SpaceX’s fleet of vehicles at the facility.
Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.
However, there are some other perspectives to consider as SpaceX is utilizing such a massive fleet of Cybertrucks. Some media outlets (unsurprisingly) are seeing this as a move of weakness by both Tesla and SpaceX, as the aerospace company is, in a sense, “bailing out” lagging sales for the all-electric pickup.
It’s no secret that Tesla has struggled with the Cybertruck this year, and deliveries have been underwhelming in the sense that the company was anticipating between 1 million and 2 million orders for the vehicle before it was widely produced.
A lot of things changed with the Cybertruck between its 2019 unveiling and 2023 initial deliveries, most notably, price.
The price of the Cybertruck swelled significantly and priced out many of those who had pre-ordered it. Some have weighed the option of whether this purchase was a way to get rid of sitting inventory.
However, it seems more logical to consider the fact that SpaceX was likely always going to transition to Teslas for its fleet, especially at Starship, at some point.
It doesn’t seem out of the question that one Musk company would utilize another Musk company’s products, especially considering the Cybertruck has been teased as the vehicle that would be present on Mars.

Elon Musk subtly confirms one of Tesla AI8’s uses, and it’s literally out of this world
Elon Musk appears to have subtly confirmed that Tesla’s upcoming AI8 chip won’t be limited to vehicles or robots alone.
														Elon Musk appears to have subtly confirmed that the uses of Tesla’s upcoming AI8 chip won’t be limited to vehicles or humanoid robots alone.
If Musk’s recent responses on X are any indication, it would appear that Tesla’s AI8 will be used by the CEO’s other companies, and its applications would literally extend out of this world.
Tesla’s AI8 could extend beyond vehicles
Musk’s update came on the heels of his recent comments, where he revealed that Tesla was not just working on its AI5 and AI6 chips. The company is also designing AI7 and AI8. This comment caught a lot of attention, with some wondering why Tesla feels the need to design an AI8 chip when AI4 seems on track to be a good fit for autonomous driving.
Amidst these speculations, an X user suggested that Elon Musk’s comment about AI8 being out of this world could actually be quite true in the literal sense, as it could be used as the chip for SpaceX’s orbit data centers. Musk subtly confirmed this, as he responded to the X user’s post with a bullseye emoji.
Musk’s subtle confirmation that AI8 will be used by SpaceX’s in-space data centers presents a pretty interesting future for the electric vehicle maker. Synergy among Elon Musk-led companies is nothing new, but having Tesla produce chips for SpaceX is undoubtedly something that’s never really been done before.
SpaceX’s space-based computing with Starlink V3 satellites
Musk previously stated that SpaceX plans to use its Starlink V3 satellites to develop space-based data centers. In response to an Ars Technica report on autonomous space construction, he wrote on X: “Simply scaling up Starlink V3 satellites, which have high-speed laser links, would work. SpaceX will be doing this.”
The concept, while ambitious, could address growing energy and cooling constraints facing Earth-based data centers amid the AI boom. Space-based clusters could also cut down on land and water usage, though critics have questioned their cost and maintainability.
Musk recently called the orbital data center project “a very big deal,” and given SpaceX’s history of turning improbable ideas into operational systems, it may not be too far-fetched at all, especially since SpaceX’s Starlink V3 platform is capable of up to 1 terabit per second (Tbps) throughput.
