Tesla participated in Hot Chips 34 and shared a ton of mind-boggling information about their Dojo supercomputer and chip architecture.
The details shared about Dojo in Hot Chips 34 by Tesla’s Emil Talpes, who worked at AMD for about 17 years for Opteron processors, are only about the hardware and capabilities of the tiles and Dojo as a whole. The performance will be discussed at Tesla’s AI Day II on September 30th.
The goal with Dojo is, according to Musk, “to be really good at video training. We have probably the fourth or approaching the third most powerful computing center in the world for AI training. Our first goal with Dojo is to make it competitive and be more effective and neural net training than a whole bunch of GPUs.”
Since Tesla needs a lot of computing power to process the video data from the vehicles in its fleet, it has built a proprietary system-on-wafer solution. According to ServeTheHome, “Each D1 die is integrated onto a tile with 25 dies at 15kW. Beyond the 25 D1 dies, there are also 40 smaller I/O dies.”
All of the power and cooling is integrated directly on the Training Tile, which is capable of 10 TB/s on-tile bisection bandwidth and 36 TB/s off-tile aggregate bandwidth. This architecture allows for the tiles to be scaled with 9TB/s links between them. They can also be plugged in and do not require their own server.
“The defining goal of our application is scalability,” Talpes said at the end of the presentation. “We have de-emphasized several mechanisms that you find in typical CPUs, like coherency, virtual memory, and global lookup directories just because these mechanisms do not scale very well when we scale up to a very large system. Instead, we have relied on a very fast and very distributed SRAM storage throughout the mesh. And this is backed by an order of magnitude higher speed of interconnect than what you find in a typical distributed system.”
The inside look into what Tesla’s building behind the scenes continues to prove how and why Tesla is at the forefront in artificial intelligence and neural net training. It gives the Tesla community an added sense of comfort knowing that Tesla will always have scalability and innovative technology at the forefront of everything the automotive company does.

In the latest episode of Jay Leno’s Garage, Tesla’s VP of Vehicle Engineering, Lars Moravy, confirmed that the new Model Y will feature adaptive headlights.
As Moravy was talking about the updated headlights in the vehicle, which now sit a few inches lower than before, he stated that in a couple of months, Tesla will add adaptive headlights in the U.S.
While Tesla has already introduced adaptive headlights in Europe and the Indo-Pacific, the feature has yet to make its way to North America.
Originally delayed in the U.S. due to regulatory issues, manufacturers have been able to implement adaptive headlights since mid-2024. Meanwhile, competitors like Rivian and Mercedes-Benz have already rolled out their own full matrix headlight systems, matching what’s available in other regions.
Update: This article has been updated to clarify that adaptive headlights will indeed be launched in the U.S., shortly after the vehicle launching in March.
Currently, Tesla in North America supports adaptive high beams and automatic headlight adjustment for curves, but full matrix functionality has yet to be rolled out. Meanwhile, matrix headlights are already available in Europe, where they selectively dim individual beam pixels to reduce glare for oncoming traffic and adapt to curves in the road.
It was surprising that matrix functionality wasn’t included in the comprehensive 2024 Tesla Holiday Update. This feature would likely improve safety ratings, so we can only assume Tesla is diligently working to secure regulatory approval.
Adaptive Headlights on Other Models
Lars didn’t confirm whether the refreshed Model Y comes with the same headlights as the new Model 3 and the Cybertruck, instead simply calling them "matrix-style” headlights.
The headlights on the new Model Y appear very similar to those available in the 2024+ Model 3, possibly meaning these other models will also receive adaptive headlight capabilities in the next couple of months.
For vehicles with older-style matrix headlights, it’s unlikely that adaptive beams support will launch at the same time, but they will hopefully become available soon afterward.
For the first time since launching Tesla Insurance in 2019, Tesla will begin underwriting its own policies, starting in California.
Tesla Insurance originally debuted in California and has since expanded to several U.S. states. Until now, policies were underwritten by State National, a subsidiary of the Markel Insurance Group. However, Tesla is now transitioning to fully in-house underwriting, beginning with its home state.
As part of this shift, California Tesla Insurance customers who receive an in-app offer to switch will be eligible for a one-time 3% discount on their next term’s premium—covered entirely by Tesla Insurance.
What is Underwriting
Underwriting is the process an insurance company uses to assess risk and determine whether to offer coverage, at what price, and under what terms.
Insurers evaluate factors such as driving history, credit score, age, vehicle type, and location. In Tesla’s case, vehicle driving data (not available in California) also plays a key role in risk assessment. These factors help classify drivers into risk categories, which influence their base premium.
From there, coverage limits, deductibles, and policy inclusions or exclusions can further adjust the final premium up or down.
Robotaxi and Other Benefits
At first glance, underwriting insurance might seem like a complex and costly process for Tesla. However, there are several compelling reasons why this move makes sense.
Insurance Income: Insurance is a highly profitable industry. Companies set rates based on risk, offering lower premiums to safer drivers and higher rates to riskier ones. This not only maximizes profitability but also incentivizes safer driving behavior, reducing overall claims.
Data Advantage: Tesla collects vast amounts of driving data through its Safety Score system. While California doesn’t allow Safety Score to impact premiums, Tesla can still use this data in the underwriting process to refine risk assessments and pricing for its vehicles.
Control Over Repair Costs: By underwriting its own policies, Tesla gains direct control over repairs and total loss decisions. This allows them to dictate when, where, and how repairs are done, optimizing costs for parts, labor, and service while ensuring vehicles are fixed according to Tesla’s standards.
FSD-Driven Discounts: Tesla has already begun offering insurance discounts for drivers using Full Self-Driving (FSD). By underwriting its own policies, Tesla could expand these incentives, potentially offering greater discounts to frequent FSD users in the future.
Preparing for Robotaxi: Perhaps the biggest long-term reason for this shift is the June launch of the Robotaxi fleet. How will Tesla insure these vehicles? The answer is simple—by underwriting its own policies and assuming liability.
Tesla’s decision to underwrite its own insurance isn’t just about cutting out middlemen—it’s a step toward lowering costs, increasing profitability, and preparing for the future of autonomous driving, a risk many insurance companies may be unwilling to make.
Further Expansion
This could be a strong sign that Tesla is preparing to expand its insurance offerings now that it has taken on the underwriting process itself. In July 2024, Tesla hired a former GEICO insurance executive to lead the expansion of Tesla Insurance and help reduce costs—a move that now appears to be paying off.
Rather than a traditional expansion, Tesla has instead made a bold move by bringing underwriting in-house, something few expected. However, it aligns with Tesla’s strategy of vertically integrating and controlling key aspects of its business, whether in manufacturing, software, or now, insurance.
If this pilot program proves successful, it could pave the way for Tesla Insurance to launch in more states—and potentially even other countries. With 2025 shaping up to be a pivotal year, we may see Tesla accelerate its insurance expansion sooner than expected.
