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.

SpaceX’s Starlink product has just gotten its latest airline adoptee, and the move marks the successful partnership of three of the “Big Four” U.S. airlines.
American Airlines announced on Tuesday that it would utilize Starlink in more than 500 narrowbody aircraft beginning in the first quarter of 2027. These include the Airbus aircraft in its fleet, including the new A321XLR and A321neo.
With the new partnership with American Airlines, Starlink is now present on three of the largest airlines in the country: American, United, and Southwest.
Starlink gets its latest airline adoptee for stable and reliable internet access
Starlink’s VP of Enterprise Sales, Jason Fritch, said:
“We are proud to bring Starlink on board American Airlines, delivering fast and reliable internet to passengers and crew. Whether traveling for leisure or business, Starlink enables a fully connected experience gate to gate, making every flight smoother and more enjoyable.”
Additionally, American Airlines Chief Customer Officer, Heather Garboden, said:
“As a premium global airline, we are continuously seeking out world-class partners like Starlink to deliver what our customers need and want. The addition of Starlink solidifies American as a leading airline in keeping passengers connected in flight.”
Starlink has been on a tear over the past year, as it has continued to be adopted by a wide variety of airlines as a more consistent and reliable way to provide WiFi to its passengers. It has already gained a great reputation among residential users, but its biggest commercial application appears to be how it is being used in the air.

The only airline of the Big Four not to adopt Starlink thus far is Delta, which chose to opt for the alternative, which is Amazon Leo. CEO Ed Bastian said to Bloomberg that Delta chose Amazon’s product over Starlink’s because “the opportunities, in terms of the improved bandwidth with a much lower price point than what we’ve ever seen from Starlink, will make a big difference.”
Delta will not start installing Amazon Leo until 2028.
“Of course, we expect Starlink will be warning people that we’re going to go with an inferior product,” Bastian said. “But I’m not too worried about partnering with Amazon.”
Tesla Cybertruck’s newest trim level is nearing its first deliveries just a few months after being offered for an incredible deal.
Back in February, Tesla officially launched a new trim of the Cybertruck, the All-Wheel-Drive, starting at just $59,990. It was a lot of truck for the money, especially considering what it offered the Rear-Wheel-Drive variant for last year, which was a total flop.
The $59,990 price that was offered initially was a deal due to its 325-mile range rating, powered tonneau, three bed outlets, Powershare capability, coil springs with adaptive damping for a refined suspension feel, Steer-by-Wire and four-wheel steering, a 6′ x 4′ composite bed, towing capacity of 7,500 pounds, and a powered frunk.
Tesla is now nearing deliveries of this trim, according to watcher Sawyer Merritt, as Tesla has officially started assigning VINs to people who ordered the vehicle initially:
I can confirm that Tesla has officially started assigning VINs to people who initially ordered the $59,990 Cybertruck Dual-Motor AWD, which means first deliveries should start in the coming weeks!

Earlier this month, we reported on units of the trim being spotted outside Gigafactory Texas by Joe Tegtmeyer.
Tesla Giga Texas buzzing as new Cybertruck appears to enter production
This Cybertruck trim was interesting because it was released basically out of nowhere, priced incredibly well, and gathered many orders in a small amount of time. However, CEO Elon Musk noted just days afterward that the vehicle would only be priced at this bargain level for ten days.
Tesla fans were not happy.
Awful way to treat customers – particularly when they already sent out a marketing email announcing the $59,990 truck…with zero mention of it being a limited-time offer.

However, the issues with the pricing strategy have blown over since the February unveiling event, and now that deliveries are near, Tesla fans are anticipating the truck making its way to their driveways soon.
The truck is currently priced at $69,990, and deliveries for new orders are slated for between August and September 2026.
Tesla is shipping a new feature that silences neighborhood Supercharger complaints, prompting drivers to be aware of those who might be impacted by excessive noise nearby.
Tesla is now rolling out a new location-specific “Quiet Charging Zone” that prompts drivers to lower their vehicle’s audio volume in an effort to make things comfortable for everyone, even those who are not Tesla owners.
Another beautiful example of Tesla’s vertical integration.
Neighbors were complaining about noise and commotion at this new Supercharger in San Francisco.

This is an impactful feature that will resolve many complaints from those who are living nearby.
When a Tesla plugs into this Supercharger and its media volume exceeds a certain level, the vehicle’s central touchscreen displays a polite notification: “Could you turn the volume down? Please be mindful of our neighbors.”
Accompanying the message is a prominent “Lower” button. One tap automatically reduces the audio to a more considerate level. Physical “Quiet Charging Zone” signs posted at the station reinforce the request, creating a cohesive experience that blends digital nudges with on-site reminders.
This feature highlights Tesla’s unique advantages. Unlike traditional automakers, Tesla owns both the vehicle software and the charging infrastructure.
Engineers can detect the precise location via GPS, trigger context-aware prompts, and deploy changes fleet-wide in hours or days without recalls or dealer visits. No public release notes highlighted the change, suggesting it was a quiet, site-specific rollout designed to test effectiveness before potential expansion.
These are usually referred to as “Undocumented Changes.”
Beyond immediate noise reduction, the initiative underscores Tesla’s customer- and community-focused ethos. While EVs are inherently quieter than combustion-engine vehicles, auxiliary behaviors like loud infotainment can still create friction in dense cities. Tesla’s rapid response turns potential conflict into an opportunity to demonstrate thoughtful engineering.
As Tesla expands its Supercharger network, which is now open to other EVs in many places, features like location-based quiet modes could become standard tools for harmonious integration into neighborhoods.
