This morning Elon Musk announced on X that Tesla is releasing FSD v12.4.1 to employees today.

FSD v12.4 was released to employees on May 20th and was expected to go out to Tesla owners the following week. However, it looks like Tesla needed to fix some issues before rolling out the update publicly.

Improvements in FSD v12.4

FSD v12.4 is expected to be a vast improvement over the current version of 12.3.6. According to Musk, it's expected to include:

Improve comfort by reducing hard braking and acceleration
Retrained models
Reduced interventions by a scale of 5-10x
Removal of the steering wheel nag
Autopark when arriving at a destination

According to the release notes, there will also be an improved strike system in FSD v12.4. Tesla will start removing a strike for every week that you go without gaining any new strikes.

If you reach five strikes (or three with vehicles without a cabin camera), then you'll still be suspended for a week.

Improved Interventions

Musk previously said that FSD v12.4 will see a big decrease in interventions with Tesla’s estimates being a reduction of 5-10x. In his post today, he talked a little bit about FSD v12.5 and v12.6, saying that it’s getting to the point where interventions may be more than a year apart.

Musk also said that the improvements in v12.4.1 are so big that it should arguably be called v13. Although Musk is known for hyping FSD releases, the list of improvements above does indicate a massive release.

Who's Eligible to Receive FSD v12.4.1

There's a lot of confusion and frustration right now around Tesla branches.

Unfortunately, FSD v12.4 is update 2024.9.5, which means that only users on 2024.8.x and below would be eligible to receive this update. This is why if you're on update 2024.8.9 or 2024.3.25, you haven't been updated to the Spring Update (2024.14). Tesla wants to make sure you are eligible for FSD's latest release.

Since Tesla isn't updating FSD owners in the US and Canada to 2024.14, we expect FSD v12.4.1 to still be based on the 2024.9 branch. So unfortunately it appears that FSD users will have to wait a bit longer for Tesla's beautiful redesign in update 2024.14.

Updated Release Date

Musk also provided a new estimate for the release of FSD v12.4.1 to customers. He stated that if all goes well with the employee release today and during testing the update will start rolling out in a limited fashion to customers this coming weekend. This could mean that we just have to wait a few more days until a lucky few start receiving the latest FSD improvements.

Tesla To Launch Four New Battery Cells in 2026

According to an article published by The Information in early October, Tesla intends to introduce four new types of 4680 batteries in 2026. We already know that Tesla has been working hard on new batteries. The Cybercell - the upgraded 4680, is already a new design meant specifically to get the Cybertruck and future vehicles off the ground.

Tesla has also been working on Solid-State Batteries, but even with Tesla’s technological and engineering prowess, that technology is still quite far out.

The 4680 Cell

To put things in context, the 4680 cell is Tesla’s replacement for the older 2710 cells present in most Model 3s and Model Ys. Tesla has been producing these cells for a long time and has optimized them considerably, both in terms of scale of manufacturing and engineering.

But the tech behind the 2170 cell is old, and 4680 will be Tesla’s next leap forward. They previously tried with the much-maligned 4680 Model Y, but it was quickly pulled from sale. They tried again with the Cybercell—and that went much better. So much better, in fact, that Tesla is working on enhancing the Cybercell even further—using a Dry Cathode Process to make the cell easier and cheaper to manufacture.

The Trouble with 4680

According to The Information, an inside source at Tesla has said that Tesla is losing 70-80% of its anodes—one of the two parts that move electrons from the cell to the vehicle—in test production. Tesla has been working hard to solve this, and they recently demoed a Dry Cathode Process Cybertruck.

The 4680 cell is the next leap in large battery packs, but it's a difficult leap to make. Tesla is having trouble moving its research and development to engineering, but it's just a matter of time. Today, the 4680 is primarily made at the Fremont factory in California, but Tesla intends to move parts of its future battery chain production to a new area outside Giga, Texas.

With that new zone, they intend to establish the 4680’s dry cathode process production facility—to produce the 4680D Cell. According to Musk, that move will cut the 4680's production costs by nearly 30%.

The New Batteries

The four cells that Tesla plans to introduce in 2026 have some interesting code names. The first is “NC05.” The NC stands for New Cell, but we’re sure Tesla will come up with a witty name once it comes out of R&D.

NC05 Battery

This cell is intended to be the easy-to-manufacture cell that will power the Cybercab and will likely also power the lower-cost $25,000 model—which we’re still expecting to see sometime next year.

NC20 Battery

The next size up, the NC20, is intended to power Tesla’s SUV lineup and the Cybertruck. This will be a larger-format cell intended for moving larger and heavier vehicles and possibly optimized for towing—a constraint the Cybertruck, on its current 4680s, can find challenging in harsh winter conditions.

NC30 & NC50 Batteries

The NC30 and NC50 are the other two cells that The Information lists, but they’ll be drastically different. They won’t be using the standard cell materials that we’ve seen used up to this point. This is where the focus of Tesla’s R&D likely lies - they intend to introduce cells using silicon carbon into the anodes. Silicon Carbon, or SiC, can hold and move electrons faster than traditional anode materials.

These cells are likely where Tesla will make significant strides in both faster charging times and improved energy output. The advanced anode design, which allows for greater energy transfer, is poised to play a crucial role in Tesla's push for ultra-fast Supercharging.

The NC30 will eventually end up in the Cybertruck and Tesla’s future SUV lineup - maybe a refreshed Model X or Model Y.

The NC50, on the other hand, will be focused on performance and a smaller cell. It’ll power the new Tesla Roadster and likely Tesla’s performance models, such as the Plaid, Performance, and Beast variants.

The Information didn’t provide any information on whether Tesla will utilize this tech on its Powerwalls or Megapacks just yet, but it's likely that both of those two products will see further cost optimization and efficiency gains as well.

We’re excited to see where Tesla takes its battery tech in the future, as charging times and vehicle range are still one thing preventing the mass adoption of electric vehicles.

We're Launching Our Redesign: See What's Included

We’ve been working behind the scenes on a few updates for our readers. We recently saw the unveiling of the Robotaxi and even some leaks of the Model Y refresh. This time, it's our turn for a refresh.

Let’s take a quick peek at the changes coming next week.

New Navigation

One key feature of our site refresh is an updated navigation. The new nav better organizes our content under one of three sections: News, Software Updates, or Guides. Once you tap on a category, you’ll be presented with the pages for that section.

This will also allow us to expose a lot more of our news content — letting you dig down into Robotaxi news, Project Juniper, or specific models. In a future update, we’ll also introduce a new Popular section, letting you easily catch up on news by viewing the best content on the site.

Dark Mode+

Along with the new navigation and some tweaked site colors, we’re also happy to introduce an updated dark mode with new, smoother colors that will be easier on the eyes. It’ll keep our night owls happy and keep your eyes nice and comfy whether you’re using it during the day or night.

Auto-Updating Statistics

Not a Tesla App

We recently also launched auto-updating statistics for each of Tesla’s software updates. These stats let you view the number of installations and rollout of each Tesla update, giving you a better idea of which updates are still rolling out and which are paused.

More Features

We’re also actively working on a couple of other projects, so stay tuned for more features coming soon.
