Key takeaways from Elon Musk’s Boring Company information session
Elon Musk provided a number of insights about The Boring Company’s Los Angeles tunneling initiatives in an information session held Thursday night at the Leo Baeck Temple. The event was led by Elon Musk and SpaceX Director Steve Davis, who was listed in the company’s recent SEC filing. Here are the key takeaways from information session.
- The Boring Co.’s tunnel boring machines are all-electric, making them 3x as powerful than conventional tunnel boring machines. Tesla batteries are used to power the machines, which eliminates the need for cabling.
- The Boring Company is aiming to drill and lay tunnel walls simultaneously while excavating dirt from the tunnel using battery-electric locomotives, which are equipped with two Model 3 motors.
- Musk and Davis also discussed the Boring Bricks, interlocking bricks made from tunneling rock. Musk noted that the Boring Bricks, which could be used for affordable housing, are better than cinder blocks. Egyptian model kits, featuring designs like the Temple of Horus, will also be sold.

- The Urban Loop transit — electric pods that are designed for commuters — will cost $1 per ticket. The speed of the Urban Loop will be 150 mph, and will enable travel from downtown Los Angeles to LAX airport in 8 minutes. Each pod can carry a maximum of 16 people.
- The Boring Co. tunnels will support Hyperloop technology as well. Just like the Urban Loop’s pods, Hyperloop pods will carry a maximum of 16 people. Hyperloop pods, however, will be much faster, traveling at 700 mph.
- The proof-of-concept tunnel under Sepulveda Blvd. in LA will not be used for public transportation. There will be no street closures, nor any tunneling beneath any homes or businesses. Residents won’t “see, feel, or hear” any of the startup’s activities. Utility lines will be untouched by the project as well.

- The Boring Company will be working closely with LA Metro. Musk stated that overall, “we want to connect with and supplement transport systems” that are already in place.
- Rocket technology is being used to develop and build the Boring Co.’s tunnels, considering that a number of SpaceX engineers are working on the tunneling startup’s projects.
- Line-Storm, the company’s second tunnel boring machine, features improvements over Godot, its first TBM. According to Musk, Godot is a conventional tunnel boring machine. Line-Storm, however, is “essentially a hybrid between conventional boring machine and the Proof-Rock, which is the fully Boring Company-designed machine.” Proof-Rock will be 10-15x faster than current TBMs. Line-storm will be at least 2x faster than a conventional boring machine.
- The Boring Company will do a full Environmental Impact Report. Musk noted that the company does not “expect any issues with the EIR.” Musk, stated, however, that the EIR will likely take some time to do.
- Elon Musk teased a party before the proof-of-concept tunnel’s launch.
The Boring Company came to fruition as Elon Musk’s way of alleviating the “soul-destroying” traffic that is prevalent in America’s streets. Just before the livestream, Elon Musk and LA Metro announced that the Boring Co.’s proof-of-concept tunneling project will be going ahead as planned. A statement from LA Metro reads as follows.
“Metro leadership and CEO Phil Washington had a great meeting today with the talented staff of the Boring Company. They will coordinate with us as they move ahead with their proof-of-concept tunnel under Sepulveda Boulevard to ensure it doesn’t interfere with our Sepulveda Transit Corridor rail project. We’ll be partners moving forward.”

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.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
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.
