Which style of Tesla’s Solar Roof tile is right for you?
With the explicit goal of making solar panels as appealing as electric cars have become, Tesla CEO Elon Musk has unveiled the company’s newest product: solar roof tiles manufactured with durable, long lasting tempered-glass. The slogan, “Power from above, beauty from the street” captured the product and theme of the unveiling, which took place at Universal Studios in Los Angeles with the sun ready to set in the background.
The new roofs will be a collaboration between SolarCity and Tesla and can be combined with Tesla’s Powerwall 2 home battery. The tiles are hydrographically printed. Musk explained that this process that makes each one a “special snowflake.”
Throughout the product unveiling, Musk emphasized that these solar tiles, which will be integrated into the roof and invisible when viewed from the street, offer a much more attractive option as compared with currently-used solar technology. The tiles will be soon available to the public in four distinct styles. Each is architecturally significant to a home’s core design. Four distinct tile styles reinforce the importance of connecting an architectural past to the Tesla vision of a sustainable future. The “beautiful, affordable, and seamlessly integrated” glass tiles have significant historic origins and contemporary appeal.
Tuscan Glass Tile
This roof, sometimes called Italian Renaissance style, is an element of a home integrated with its setting. Consistent with Musk’s vision of sustainable solutions to a “mine-and-burn” hydrocarbon economy, landscape architecture and gardens balance Tuscan house design. The roof structure is a combination of side gable, cross gable, combined hip and gable, or hipped configuration, often with projecting wings and deep roof overhangs and eaves. The style borrows details from the entire history of Spanish architecture, with architectural elements of paired French doors, classic arches, and some use of wrought iron.
Slate Glass Tile
The most desirable roofing material for more than 1,000 years, slate has been acclaimed for its elegance and unique character. It required a craft person’s expertise and skill in hand shaping and laying it on the roof. The Tesla version likely will resemble thin tiles split into uniform thicknesses. Slate’s aesthetic appearance is due to a wide variety of rich colors and textures that are combined in nearly endless combinations. Found on virtually every class of structure, slate roofs are perhaps most often associated with institutional, ecclesiastical, and government buildings, yet slate was often used on farm and agricultural buildings as well.

Textured Glass Tile
Textured roofing tiles were used in Neolithic China as early as 10.000 B.C. and 5000 years ago in Babylon. By the end of the nineteenth century, as the use of glazed roofing tiles grew, textured tiles became among the most ornamental and distinctive roofing materials. Now featured on many historic buildings, their aesthetic qualities include many shapes, colors, patterns, and textures. Architecturally, a field of textured tiles often covers the majority of a roof’s flat surface, with decorative tiles used along the peak of the roof. In more ornamental installations, the field of tiles may have areas of patterning created by tiles of different shapes, dimensions, or color variations ranging from deep browns to pale pinks to buff or beige. Their interesting appearance has often made textured tile roofs prominent stylistic features of historic structures.

Smooth Glass Tile
Flat smooth tile offers clean lines that compliment a contemporary design with unassuming, no-frills elegance. It contains a straightforward, stripped-down geometry and a means of securing an organic bond between old, existing architecture and new buildings. This is particularly important in optically sensitive areas where contemporary architecture accentuates an important visual impression. All parts of the resultant ensemble stem from a single smooth tile source, which appears as if it grew up over the centuries. Smooth glass tiles can contribute to an eclectic conglomeration of heritage-listed façades and modern stylistic elements. Optically robust, these tiles now provide an interplay of nuances that was once typical of hand-crafted products.
Tying Architecture and Aesthetics to Energy Power Solutions
The Tesla solar roof tiles offer high efficiency solar power which will produce energy even during high temperature days. Color louver film allows cells to blend into the roof while exposing them to the sun above. With tempered glass, the material is extremely impact resistant. The solar integrates with Tesla home batteries to collect energy during the day for use in the evening once the sun goes down. Musk tweeted that “solar glass tiles can also incorporate heating elements, like rear defroster on a car, to clear roof of snow and keep generating energy.”
Tesla expects to start installing the solar roofs next summer. More durable than normal roofing tiles, the solar roofs can be tied to the updated Powerwall 2 home battery (14 kWh, $5500) which the company also showcased at the unveiling event.
The announcement of this solar innovation implies that the Tesla/ SolarCity merger will receive upcoming shareholder votes and approval.

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.
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.
