Elon Musk-led artificial intelligence (AI) company xAI has officially open-sourced its Grok language model, after Musk announced plans to do so just under a week ago.
Musk said last Monday that xAI would make Grok open-source, and on Sunday, the company announced the open release of the language model in a post on its website.
“We are releasing the base model weights and network architecture of Grok-1, our large language model,” xAI writes in the post. “Grok-1 is a 314 billion parameter Mixture-of-Experts model trained from scratch by xAI.”
“This is the raw base model checkpoint from the Grok-1 pre-training phase, which concluded in October 2023,” xAI adds. “This means that the model is not fine-tuned for any specific application, such as dialogue.”
“We are releasing the weights and the architecture under the Apache 2.0 license.”
The news comes following Musk’s ongoing criticisms of ChatGPT-maker OpenAI, which he helped to found but later left, for abandoning its original intent to be a non-profit with an open-source model. OpenAI received investments from Microsoft of $1 billion in 2019, and $10 billion in 2023, and Musk has pointed to the closed-source, for-profit model as an issue.
On X, the Grok account replied to Musk’s original announcement of plans to open-source the xAI model with a joke about opening its weights to the public:
░W░E░I░G░H░T░S░I░N░B░I░O░
— Grok (@grok) March 17, 2024
The ChatGPT account replied, saying, “stole my whole joke,” to which Musk responded by saying, “Tell us more about the ‘open’ part of OpenAI …”
Last month, Musk also filed a lawsuit against OpenAI and co-founders Sam Altman and Greg Brockman for breaching contracts by pursuing a for-profit, closed-source mission. OpenAI followed up with a blog post claiming that Musk had agreed to move to a for-profit model as early as 2015.
In January, Musk denied claims that xAI was raising capital, saying that he hasn’t had any conversations regarding plans to do so. Musk launched xAI last July as a competitor to OpenAI and other AI companies, later launching the Grok language model in November.

Tesla prepares for full-throttle manufacturing of major product
Tesla has the second quarter of 2026 as its projected start date for Cybercab production. It also plans to launch Semi and Megapack 3 for “volume production” starting next year, which will also be two major contributors to the company.
Tesla is preparing for a full-throttle manufacturing effort of potentially its biggest product in company history, job postings on the company’s website show.
In preparation for its foray into fully autonomous travel, Tesla is gearing up for Cybercab manufacturing with 30 job postings, ranging from repair technicians to manufacturing specialists.
Elon Musk sets definitive Tesla Cybercab production date and puts a rumor to rest
The jobs are all located in Austin, Texas, where the company’s Gigafactory Texas facility is located. This is where Cybercab production is going to take place.
Tesla has made major strides in the Cybercab project over the past few months, including launching the vehicle on the Fremont Test Track in California and conducting crash testing at Gigafactory Texas.
All of these indicate the company is preparing for an imminent production effort of the vehicle, which, as Elon Musk said during last week’s Earnings Call, will be void of a steering wheel or pedals.
Tesla has the second quarter of 2026 as its projected start date for Cybercab production. It also plans to launch Semi and Megapack 3 for “volume production” starting next year, which will also be two major contributors to the company.
Musk spoke in great detail during the Earnings Call last week about Cybercab’s potential to change the grand picture of the automotive market, comparing other vehicles in the Tesla lineup to “a little bit of the horse-carriage thing.”
He said:
“That’s really a vehicle that’s optimized for full autonomy. It, in fact, does not have a steering wheel or pedals and is really an enduring optimization on minimizing cost per mile for fully considered cost per mile of operation. For our other vehicles, they still have a little bit of the horse carriage thing going on where, obviously, if you’ve got steering wheels and pedals and you’re designing a car that people might want to go very direct past acceleration and tight cornering, like high-performance cars, then you’re going to design a different car than one that is optimized for a comfortable ride and doesn’t expect to go past sort of 85 or 90 miles an hour.”
Cybercab production is imminent, given the job postings and the company’s proposed timeline for manufacturing to begin. Of course, there is always the potential that Tesla is late to the party, as it has been with other projects.

xAI’s Grokipedia goes live, gets praise from Wikipedia co-founder
xAI’s latest creation, Grokipedia, has gone live, and even if it’s only at Version 0.1, it is already receiving positive reviews from some users.
xAI’s latest creation, Grokipedia, has gone live, and even if it’s only at Version 0.1, it is already receiving positive reviews from some users. These include Larry Sanger, the co-founder of Wikipedia, the world’s largest online encyclopedia, which has become quite controversial in recent years over accusations of bias.
Grokipedia launches
Immediately after Grokipedia went live, the AI-powered Wikipedia alternative was tested by numerous users. So far, a good number of testers have responded positively to the online encyclopedia, with many observing that Grokipedia does tend to be more neutral than Wikipedia. This was particularly evident in controversial topics, from alternative medicine to events like Gamergate.
Among these users was Larry Sanger, who noted that while Grokipedia still has a lot of areas of improvement, it is already very promising. “My initial impression, looking at my own article and poking around here and there, is that Grokipedia is very OK. The jury’s still out as to whether it’s actually better than Wikipedia. But at this point I would have to say “maybe!” He wrote in a post on X.
Musk responded to Sanger’s comments, stating that the Wikipedia co-founder’s observations are “accurate.” The xAI founder also noted in a separate X post that even in its V0.1 form, Grokipedia is already better than Wikipedia.
Why Grokipedia exists
During an interview on the Tucker Carlson Show, Sanger point out that Wikipedia has become a far cry from his initial vision for the online encyclopedia, and a lot of this was because of the its “Reliable sources/Perennial sources” page, which categories publications and sources into tiers of credibility. Sanger noted that the list leaned heavily left, with conservative publications getting effectively blacklisted in favor of their more liberal.
Musk responded to Sanger’s comments by stating that Grokipedia will be created as a step towards xAI’s broader goal of “understanding the Universe.” He added that Grokipedia, which will use xAI’s Grok, would provide broader sourcing and a freer exchange of information compared to Wikipedia’s current system.
One month after Elon Musk’s comments, Grokipedia has gone live in its V0.1 form.

Tesla Fremont Factory celebrates 15 years of electric vehicle production
Since opening in 2010, the Fremont Factory has produced all four “S3XY” models while creating tens of thousands of jobs.
Tesla is marking the 15-year anniversary of its Fremont Factory in California, the first automotive mass-manufacturing plant acquired by the electric car maker.
Since opening in 2010, the Fremont Factory has produced all four “S3XY” models while creating tens of thousands of jobs and investing billions of dollars in the region.
Celebrating 15 years of EV production
The Fremont Factory’s milestone was celebrated by the official Tesla Manufacturing account on X, which posted a photo of several Teslas forming a “15” in front of the facility’s iconic white facade. As per the electric vehicle maker, the Fremont Factory has now produced 3.6 million vehicles so far, and it has also created over 20,000 jobs in the state.
“15 years ago, we opened Fremont factory. Today, the Fremont team is producing all 4 S3XY models, totaling 3.6M vehicles made so far. 20k+ California jobs created w/ billions of dollars invested,” the official Tesla Manufacturing account on X wrote in its post.
The Fremont Factory’s transformation
Tesla acquired the Fremont Factory from the defunct NUMMI joint venture between General Motors and Toyota in May 2010 for $42 million. The facility had produced more than 8 million vehicles under GM and Toyota over 26 years. Following its acquisition, Tesla retooled the 5.3-million-square-foot plant to support the production of the Model S sedan.
Over the past 15 years, the factory has evolved into Tesla’s primary North American production hub, assembling the Model S, 3, X, and Y. Annual output has exceeded 550,000 vehicles, including nearly 560,000 produced in 2023 alone. Expectations are high that other products, such as the next-generation Roadster and Optimus, might be produced in the Fremont Factory as well.
