The Boring Company files permit to extend tunnel project in Los Angeles
Elon Musk’s The Boring company has filed a permit with Los Angeles to extend its tunnel project within city limits. A spokesperson for the Bureau of Engineering, Mary Nemick, confirmed the filing made by Musk’s tunnel digging venture though no further details were provided.
The Tesla and SpaceX CEO previously revealed plans to build an underground tunnel beginning near LAX airport and continue along the westside of Los Angeles, into the San Fernando valley. “First route will go roughly parallel to the 405 from LAX to 101, with on/offramps every mile or so. It will work like a fast freeway, where electric skates carrying vehicles and people on pods on the main artery travel at up to 150mph, and the skates switch to side tunnels to exit and enter.” said Musk.
Los Angeles Mayor Eric Garcetti, who’s historically been a big proponent of Musk and his projects, took to Twitter on Wednesday to welcome The Boring Company’s forward-thinking vision for the city’s transportation system. “Los Angeles has always been a place where innovators come to build new ideas that can change how we live our lives,” said Garcetti. “We look forward to continuing our conversations about this new transportation technology, and exploring the ways that it can help us build a better future for our city.”
If approved, the newly filed permit will allow Boring Co. to dig beyond the existing 2-mile test tunnel that’s currently being constructed beneath 120th street near SpaceX’s headquarters in Hawthorne, CA.
Hawthorne Mayor Alex Vargas said in August, after The Boring Company won city council approval for its tunneling project, “The city of Hawthorne is excited to see the rapid progress at which the tunnel is being completed, we are looking forward to seeing Elon Musk begin testing his system and making subterranean travel a reality here in our city.”

The company has been testing a prototype of an electric skate that will be used to transport vehicles at high speeds within a 13.5 foot diameter tunnel that’s located 44 feet below ground. According to documents submitted to the city council, “The test tunnel project would involve SpaceX engineers repeatedly testing personal vehicle types suitable for placement on the skates; refinement of the design and technology; and general data collection on performance, durability, and application,”
As The Boring Company awaits approval to extend its tunneling project into the westside of Los Angeles, Musk and team will continue to iterate on streamlining the process for tunnel building. Unlike traditional underground tunnels for passenger vehicles, Boring Co.’s tunnels will be smaller and able to maintain a vacuum in order to support Hyperloop transportation. Reducing the tunnel diameter by 50% will also reduce the cross sectional area of the tunnel by a factor of four. Musk noted in his speech at TED2017 that having a smaller tunnel just large enough for a vehicle will cut 75% of the time associated with digging, thereby introducing a significant cost savings. The Boring Company’s tunnel boring machine will also look to install tunnel walls continuously while it digs, thus eliminating the need to pause operations and speeding up the process entirely.
In addition to its project in California, the company received approval by Maryland officials to dig a 10.1-mile tunnel that aims to connect Baltimore with Washington, DC. Maryland Governor Larry Hogan said in a Facebook post on October 19, “Incredibly excited to announce our administration’s support for The Boring Company to bring rapid electric transportation technology to Maryland, connecting Baltimore City and Washington D.C.”

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.

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.
