Tesla Semi gets closer to production amid test drive event for reservation holder
If Elon Musk’s initial timeframe for the Tesla Semi is accurate, initial production for the all-electric long-hauler should begin sometime this year. While Tesla has been tight-lipped about where the vehicle would be manufactured, the company appears to be showing confidence that the Semi is getting closer to production. Take, for one, the test drive events that Tesla has been holding with some of the Semi’s reservation holders.
On Wednesday, truck leasing company TCI Transportation shared a post on its official Twitter account. The company noted that they were visited by the Tesla Semi, and that some of its employees were even given test drives on the vehicle. Images from the event show TCI’s employees inspecting the all-electric long-hauler, and everyone in the event sharing a meal together.
TCI Transportation is not one of the companies that announced reservations for the Tesla Semi immediately after the vehicle was unveiled. Instead, the truck leasing company posted about its electric truck order last April, stating that they have ordered 50 units of the Tesla Semi. In its announcement, TCI noted that co-Presidents Ryan and Andrew Flynn were able to take the Semi out for a spin.

Perhaps interestingly, TCI’s recent post about the Tesla Semi saw the truck leasing company describe the all-electric long-hauler as a “new Tesla Semi Tractor Prototype,” a curious way of describing the vehicle. In its announcement last year, TCI simply called the vehicle as the “new Tesla Electric Semi truck.” While this difference could simply be a matter of simple syntax, the Semi’s new description from the leasing firm invokes the idea that the electric truck has probably been improved to a degree over the past year.
Tesla, after all, has been doing real-world tests using the Semi’s silver test mule. Not long after the vehicle was unveiled, the Semi had been spotted doing cargo runs or running routes across the United States — and it has not really stopped since. Even the matte black Semi prototype, which was recently wrapped in a stunning red color, has been spotted several times testing on America’s roads.
Through these tests, Tesla continues to refine the electric long-hauler, ensuring that the truck is at its best iteration possible when it enters production. Elon Musk already teased some of these improvements in the past. For example, Tesla initially announced two range options for the Semi — a 300-mile short range variant and a 500-mile long range version. In later statements though, Musk stated that the long-range variant of the Semi would have closer to 600 miles of range per charge.
When the Tesla Semi was initially unveiled, the vehicle attracted a notable amount of skepticism from some established players in the legacy trucking market. Daimler Trucks CEO Martin Daum, for one, infamously even joked that the specs Elon Musk quoted for the Semi suggest that the vehicle defies the laws of physics. In a more recent statement, though, Daum was far less dismissive. While the Daimler Trucks CEO still maintained that Tesla would have challenges breaching the trucking market, Daum nonetheless admitted that Tesla has shown that it has the determination to move forward.
“They’re fun; it’s an interesting market. We take every competitor seriously; Tesla has proved they really have the tenacity to really go through huge losses to capture the market. But trucking is a difficult business. They will learn the hard way; trucking is not like passenger cars where one size fits all. There’s a lot of variety in trucking… the United States is a highly competitive market, so as I said, they’re fun,” Daum said.

Tesla confirms that work on Dojo 3 has officially resumed
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo 3,” Elon Musk wrote in a post on X.
Tesla has restarted work on its Dojo 3 initiative, its in-house AI training supercomputer, now that its AI5 chip design has reached a stable stage.
Tesla CEO Elon Musk confirmed the update in a recent post on X.
Tesla’s Dojo 3 initiative restarted
In a post on X, Musk said that with the AI5 chip design now “in good shape,” Tesla will resume work on Dojo 3. He added that Tesla is hiring engineers interested in working on what he expects will become the highest-volume AI chips in the world.
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo3. If you’re interested in working on what will be the highest volume chips in the world, send a note to AI_Chips@Tesla.com with 3 bullet points on the toughest technical problems you’ve solved,” Musk wrote in his post on X.
Musk’s comment followed a series of recent posts outlining Tesla’s broader AI chip roadmap. In another update, he stated that Tesla’s AI4 chip alone would achieve self-driving safety levels well above human drivers, AI5 would make vehicles “almost perfect” while significantly enhancing Optimus, and AI6 would be focused on Optimus and data center applications.
Musk then highlighted that AI7/Dojo 3 will be designed to support space-based AI compute.
Tesla’s AI roadmap
Musk’s latest comments helped resolve some confusion that emerged last year about Project Dojo’s future. At the time, Musk stated on X that Tesla was stepping back from Dojo because it did not make sense to split resources across multiple AI chip architectures.
He suggested that clustering large numbers of Tesla AI5 and AI6 chips for training could effectively serve the same purpose as a dedicated Dojo successor. “In a supercomputer cluster, it would make sense to put many AI5/AI6 chips on a board, whether for inference or training, simply to reduce network cabling complexity & cost by a few orders of magnitude,” Musk wrote at the time.
Musk later reinforced that idea by responding positively to an X post stating that Tesla’s AI6 chip would effectively be the new Dojo. Considering his recent updates on X, however, it appears that Tesla will be using AI7, not AI6, as its dedicated Dojo successor. The CEO did state that Tesla’s AI7, AI8, and AI9 chips will be developed in short, nine-month cycles, so Dojo’s deployment might actually be sooner than expected.

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.
