Are hydrogen cars competition for Tesla?
Reading the news and making sense of PR pitches is an art and a science. The art is reading through the pitches, determining where the motivation is and what lies behind. The science is re-articulating the message behind pitches. The latest news campaign is that hydrogen fuel cells cars are competition to Tesla and electric vehicles (EV).
Sifting through the news
Are hydrogen fuel cell cars competition to EVs? And if so, how are they competing? Those are basic, relevant questions we need to keep in mind when reading the news. Matthew Levy on Seeking Alpha believes Toyota and Hyundai’s hydrogen fuel cell vehicles compete with the Model S. The truth is, Toyota and Hyundai are not in the same league as Tesla Motors in terms of their respective segments and innovations.
The article tries to make a point that by opening the doors to its charging protocols, Tesla won’t sue those who use these protocols in good faith. The article argues that Tesla’s new competitors are growing, but include the Detroit VIA Motors that converts pickup trucks to plug-in hybrids (PHEV) and Harley-Davidson’s new and loud Project LiveWire, a noisy electric motorcycle I covered on CarNewsCafe. According to Matthew Levy: “While these are not direct competitors to Tesla’s sedans, they do show the shift in attention to electric vehicles. Combined with Chevrolet’s Volt (GM) and the Nissan Leaf, the electric vehicle market is becoming crowded behind Tesla. With the availability of Tesla’s patents to other electric vehicle manufacturers (who have more resources than Tesla), the gap should continue to shrink.”, indeed, it will and it should. No one would argue that, least of all Elon Musk.
The article points to a theoretical advantage Tesla has over the competitors. “With the same driving range on the upgraded models,” we suppose the article refers to the P85, “as well as much longer charging times,” larger tanks take longer to fill as well, “the Model S only holds a slight advantage over its hydrogen competitors, if any.” Really? How so? Try an encyclopedia of advantages. It is a full electric vehicle that comes with the freedom of choice of accepting your very own home 110V outlets, your dedicated 240V plug, your home high-powered Tesla charger, the option for the free Supercharger, depending on your time to recharge and where you are. Now, add to this the fact that you and I can make electricity from solar energy, wind, hydro, and any other alternative and renewable energy, or simply just plug it in anywhere.
These are huge advantages hydrogen does not offer yet. Using hydrogen, we go back to the pump and are not in control of the energy price. To be fair, utilities are slowing down personal alternative energy systems and are trying to inflate energy prices, but almost anyone can choose which energy origin to use for their EVs. If you don’t like the grid, install an alternative energy system at home. The same can’t be said about hydrogen fuel cell. I can build an electric motor or buy one on the cheap, I can’t do the same with a fuel cell. EVs offer energy choice, hydrogen does not yet.
The hidden message and the driving motivation
It is obvious by now that the hydrogen phenomenon hasn’t taken the world by storm. Contrary to the article, Hyundai already has a hydrogen fuel cell vehicle offered to the public and Honda has had its Clarity for lease since 2008. Hydrogen fuel cell has its place in the world of energy, but so far it’s been limited to places where solar panels have limited application without better energy storage. Who is driving the push for hydrogen fuel cells when we already have proven EVs, such as the Model S that uses commodity batteries and achieves close to 300 miles? The question to ask is who has benefited the most from the automobile this past century.

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.
