Tesla formally wins final environmental approval to open Gigafactory Berlin
The wait is finally over. After a long process that saw delays, controversies, and other drama, Tesla Gigafactory Berlin has won its final environmental approval from Germany. An official document confirming the update was published by the State of Brandenburg, outlining the next steps that the electric vehicle maker needs to do to start vehicle production in its Germany-based electric vehicle factory.
As per the state’s press release, the approval for Giga Berlin covers several activities, such as the production of up to 500,000 vehicles per year. The approval also includes battery cell production activities within the Giga Berlin complex, which should allow Tesla to manufacture its in-house cells from within Germany.
“The project, which was approved with the 536-page decision, includes the plant for the production of up to 500,000 vehicles per year, aluminum smelting plants and an aluminum foundry, plants for surface treatment, heat generation, and storage. The facility also includes battery cell production, an operational wastewater treatment plant, a fire brigade equipment house, a high-bay warehouse, as well as laboratories and workshops,” the press release read.
It should be noted that while it may have taken two years to get to this point, Gigafactory Berlin’s formal approval was still completed in a quick manner, at least relatively speaking. The past two years, after all, required the State Office of the Environment to not only inspect and approve the factory itself, but also the entire industrial area with several large-scale facilities. Environment Minister Alex Vogel expressed his thanks to the state’s employees and other authorities for Giga Berlin’s quick approval process.
“As a high-performing state administration, you have always focused on the technical requirements, the high level of protection of the environment, the protection of the general public and the neighborhood from dangers, even under the pressure of great public interest and unreasonable harassment as well as the legal certainty of the procedure. In times of climate crisis, the availability of water will play an increasingly important role for future developments and settlements. Above all, digitization can help to simplify and accelerate processes without restricting environmental standards and participation rights,” Vogel said.
District Administrator Rolf Lindemann emphasized that Giga Berlin benefits the region. The fact that the project faced much adversity, and was still able to achieve a milestone such as a final environmental approval in a relatively short time, proves that the project’s potential is vast. He also noted that Giga Berlin, as well as those that have been working with Tesla over the past two years to approve the project, shall face whatever challenges lie ahead with vigor.
“The Oder-Spree district described the Tesla Gigafactory as a real stroke of luck for the development of our region. We have therefore mobilized all our strength to help turn this unique opportunity into a visible success. It wasn’t always easy, and we’re anything but done when it comes to the final form of the overall project. But we all have reason to be proud of what we have achieved so far, despite all prophecies of doom.
“That is why we will face the further challenges that lie ahead with confidence and with undiminished vigor. I am referring to the official support of the further expansion stages, the completion of the battery factory and of great importance, especially for local politics: as far as possible, a stress-free integration of the Gigafactory into the traffic infrastructure . However, in order to be able to meet the sustainability aspect and smooth mobility in connection with production, it is of course necessary to start building housing close to the location and to create the associated social infrastructure. We trust in the same support from the state government that we have been able to rely on in the past,” Lindemann said.
While Giga Berlin’s final environment approval has been secured, Tesla still has to ensure that it meets the state’s requirements. These are highlighted by the mammoth size of its approval documents, which comprise over 23,700 pages in 66 files. More than 400 ancillary provisions are included, involving topics such as requirements for groundwater protection as well as water-saving and wastewater-reducing measures, species protection measures, limit values for air pollutants and regulations on their measurement as well as occupational safety requirements. Other specific rules on the plant’s operations, particularly with regards to how it affects the area’s groundwater, were also highlighted in the press release.
“There are 113 air pollution control requirements, which include respective chimney heights for each exhaust air stream. In addition, 22 requirements determine the methods and intervals at which the exhaust air is to be measured. 96 requirements for drinking water protection, waste water disposal and rainwater specify, among other things, limit values for discharge into the waste water pressure line and corresponding cleaning processes. When using building materials, it is important to ensure that no harmful substances get into the groundwater. With groundwater monitoring, both the formation of new groundwater and the quality of the groundwater must be checked regularly. In view of the tense water situation, not least due to climate change, it should be possible to react to changes as early as possible.
“After the inspection by the approval authority, the entire system falls under the provisions of the Hazardous Incidents Ordinance (12th BImSchV) and must therefore take special precautions to prevent incidents and limit the effects of incidents, as well as maintain an appropriate safety distance from adjacent protected objects. Tesla must draw up an incident concept and comply with special information obligations,” the press release read.
The state noted that Tesla may now start or continue with the further construction of Giga Berlin and that objections to the project now have “no suspensive effect.” It should be noted, however, that before Tesla can actually put its Model Y production facility into operation, several ancillary provisions must be met first. These provisions, which include the installation of measuring devices for air pollutants and precautions for fire protection and accidents, will be checked by the responsible authorities. Once Tesla completes this step, Model Y production for customer vehicles could finally commence.
Needless to say, all eyes are now focused on how quickly Tesla can meet the requirements for Giga Berlin’s operational permit.

Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
Tesla set to launch “Terafab Project: A vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla is making one of the boldest bets in its history. On March 14, Elon Musk posted on X that the “Terafab Project launches in 7 days,” pointing to March 21, 2026 as the start date for what he has described as a vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla first confirmed Terafab on its January 28, 2026 earnings call, where Musk told investors the company needs to build a chip fabrication facility to avoid a supply constraint projected to materialize within three to four years. But the seeds were planted even earlier. At Tesla’s annual general meeting last year, Musk warned that even in the best-case scenario for chip production from their suppliers, it still wouldn’t be enough, and declared that building a “gigantic chip fab” simply had to be done.
While there has been no official announcement on where Tesla plans to break ground on the massive Terafab, all signs point to the North Campus of Giga Texas in Austin.
Months of speculation has surrounded Tesla’s North Campus expansion at Giga Texas, where drone footage captured by observer Joe Tegtmeyer revealed massive construction site preparation just north of the existing factory on a scale that rivals the original Giga Texas footprint itself.
Samsung’s Tesla AI5/AI6 chip factory to start key equipment tests in March: report
The project is projected to produce 100–200 billion AI and memory chips annually, targeting 100,000 wafer starts per month, at an estimated cost of $20 billion. Tesla is targeting 2-nanometre process technology and anticipated to be the most advanced node currently in commercial production. Dubbed the Tesla AI5 chip, the chip will pack 40x–50x more compute performance and 9x more memory than AI4, and will be among the first products Terafab factory is set to produce. This highly optimized, and massively powerful inference chip is designed to make full self-driving (FSD) and Tesla’s Optimus robots faster, safer, and with full autonomy.

This is where Terafab becomes a genuine game-changer. If Tesla successfully builds a 2nm chip fab at scale, it becomes one of only a handful of entities that’s capable of producing AI silicon in-house, with competitive implications that extend far beyond Tesla’s own vehicles, and potentially positioning Tesla as a chip supplier or licensor to other industries.

The next-gen Tesla AI chips will power advancements in Full Self-Driving software, the Cybercab Robotaxi program, and the Optimus humanoid robot line. Musk’s projections for Optimus require chip volumes that no existing external supplier can commit to on Tesla’s timeline.Competitors like Waymo and GM’s Cruise remain dependent on third-party silicon, leaving them exposed to the same supply chain vulnerabilities Tesla is now working to eliminate entirely.
The Terafab launch this week may not mean a factory opens its doors overnight, but it signals Tesla is serious about owning the entire AI stack, from software to silicon.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.
Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of…
— Elon Musk (@elonmusk) March 11, 2026
Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.
— Elon Musk (@elonmusk) March 12, 2026
Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.
