Less than ten days since the last FSD update, Tesla has started rolling out FSD v12.3.6. Not only does this update include improvements to FSD itself, but it also adds the new Autopark and High Fidelity Park Assist to vehicles with ultrasonic sensors.

As Tesla continues to ramp up its AI training capacity, the average number of miles driven on FSD continues to climb at an increased rate.

Computing Power

Last week, in the earnings call deck, Tesla revealed that it’s set to increase its core AI infrastructure capacity “in the coming months.” Tesla stated it has quadrupled its capacity since September 2023.

To further improve our end-to-end training capability, we will continue to increase our core AI infrastructure capacity in the coming months. - Tesla

Musk said on Sunday that the company will spend “around $10B” throughout 2024 in “combined training and inference AI, the latter being primarily in car”. “Any company not spending at this level, and doing so efficiently, cannot compete,” he added.

Expansion to China

In an unexpected 24-hour trip to China, Elon Musk visited Beijing to meet with Premier Li Qiang to discuss the rollout of Full Self-Driving (FSD) software and permission to transfer driving data overseas. Since Tesla uses fleet data to continuously improve FSD, being able to use data gathered in and outside of China will be crucial to its continued improvement.

On the same day, Tesla models produced at Giga Shanghai were listed among the EVs that meet China's data security requirements for smart cars, an important hurdle for Tesla to surpass.

When Musk was asked on X about Tesla releasing FSD in China, Musk simply said “It may be possible very soon.”

Regarding additional markets such as Europe and Australia, Musk said he believes that v12 is “ready for supervised FSD in LHD countries” while RHD like the UK or Australia “will take a bit longer”.

Internal FSD Is 3 to 6 Months Ahead

Earlier this month, Tesla disclosed that the team knows “roughly” how the software will perform in “3 to 6 months”. He added that it takes “a few months to fix those bugs and complete safety tests” before releasing the version to the Tesla employees and then to the general public.

Major FSD Updates Coming

On X, Musk teased that the next major update to FSD will be v12.4, saying “it’s awesome,” and that it’s “another big jump in capabilities.” Musk said that Tesla’s computing constraint has been much improved, and likely may be a factor in this further being another big improvement.

In mid-March, Elon Musk announced that Tesla will reintroduce Smart Summon and Autopark to its vehicles. Tesla has now delivered on the Autopark promise, but we’re still waiting on the improved Smart Summon feature. It’s possible we’ll see in FSD v12.4.

Tesla Activates In-Cabin Radar in Software Update 2025.2.6

Tesla has released software update 2025.2.6, and while minor updates typically focus on bug fixes, this one introduces a major new feature. With this update, Tesla has activated the in-cabin radar, a sensor that has been included in some vehicles for more than three years but remained unused until now.

Why Not Vision?

Unlike vision-based systems, radar can precisely measure object dimensions and even detect movement behind obstacles by bouncing radio waves off surrounding surfaces. This allows for more accurate and reliable measurements of objects that vision may not even be able to see, such as behind the front seats.

What Tesla Announced

Tesla recently highlighted the 4D radar in the new Model Y, explaining how it will improve passenger safety. Tesla executives stated that the radar would be used to properly classify passengers and improve the way airbags deploy.

Tesla went on to say that in a future update, Tesla will use the in-cabin radar to detect any potential passengers left in the vehicles. Since radar can even pick up on heartbeat and breathing patterns, it can provide a much more accurate method of detecting children left in a vehicle. Tesla talked about how the vehicle will send owners a notification via the Tesla app and enable the HVAC system if it detects a passenger in the vehicle. It’ll even call emergency services if needed.

New Feature in Update 2025.2.6

Tesla has officially named this feature in update 2025.2.6, “First-Row Cabin Sensing Update,” which appears to align with the first portion of what Tesla discussed in the new Model Y video.

In the release notes, Tesla describes the update as:

“The first-row cabin sensing system has been updated to use cabin radar, which is now standard in all new 2025 Model Ys. Your Model Y was built pre-equipped with the necessary hardware, allowing Tesla to also bring this technology to your vehicle.”

For now, it appears that Tesla is using the radar to detect and classify passengers in the front seats. This could eventually replace traditional seat sensors, reducing the number of hardware components and lowering production costs.

Tesla plans to expand the feature later this year, bringing rear-seat passenger detection in Q3 2025. While Tesla talked about the feature for the new Model Y, we expect it to be available for all vehicles with the in-cabin radar.

Supported Models

Although Tesla is vague in their release notes, this feature is being added to all Model Ys that include a cabin radar. Tesla started including the cabin radar in 2022, but its availability may vary by region and model. The Model 3 didn’t receive the cabin radar until it was redesigned in 2024, while all Cybertrucks already include it.

The owner’s manual for the redesigned Model S and Model X doesn’t specifically mention the interior radar, although Greentheonly believes the vehicles also include one, so we’ll have to wait to determine whether those vehicles also receive this new feature.

At this time, the feature appears to be only going out to Model Y vehicles, but we expect it to become available on other supported models soon.

We love to see these kinds of updates. Tesla is increasing the safety of existing and new vehicles through a software update while also making them more affordable to own.

Tesla Updates App: Adds Robotaxi Code, New Model Y Models and New Tesla Service UI

Tesla has updated the Tesla app to version 4.42.0, and this time, it’s more than just bug fixes. The app includes a new service interface, introduces support for the new Model Y, and, for the first time, includes some code for the Robotaxi coming later this year.

This update was released for iOS and should be available on Android within a few days.

Refreshed Model Y 3D Model

First up in the update is the introduction of the 3D model for the refreshed Model Y. Interestingly, while we all know it as Juniper, the file code name inside the update lists the vehicle as “Bayberry.” The Bayberry name was introduced in Tesla app update 4.41.5.  Tesla’s internal code names sometimes change as the vehicle evolves - and we’ll continue to refer to it as the refreshed or new Model Y for ease of understanding.

As usual with Tesla’s 3D models in the app, there’s a lot of detail, although it’s not easy to see since you can pinch and zoom the model in the app. The 3D models used in the app are actually the same models that Tesla uses in the vehicle, although sometimes they include different lighting effects, but they’re all highly detailed.

Robotaxi API

Tesla has added a new endpoint in their app for Robotaxi - and it’s the very first Robotaxi or Cybercab-related item we’ve seen in the app. With the Robotaxi fleet launching in June, according to Tesla, it looks like they’re now adding support to the Tesla app.

The new app API is called “rides_feedback_upload,” which seems pretty explanatory. Tesla will need to gather a lot of information on ride quality and all the little things in between. What better way than to get feedback directly from users?

While Tesla previously released prototype images of what the Robotaxi app will look like, the introduction of this API into the Tesla app leads us to believe that Tesla will utilize the current app for Robotaxi use.

Updated Service Interface

Tesla has released an updated UI for the Tesla Service panel, and we have a ton of details on these changes. This new pane displays appointment details more prominently. If you have a service appointment scheduled, you’ll now see a lot more details on the main service screen. The app will now display:

  • Your current service status

  • Appointment date and time, which you can now tap on to add the event to your calendar

  • Address and hours of the service center. You can now also tap on the address to open up the location in your maps app

There’s also a new appointment details screen (the right portion of the image). This screen displays additional details that were previously unavailable, such as your transport type. The app will display whether you’ll get a loaner vehicle, demo vehicle, or something else.

There are a ton of user experience (UX) improvements in this update regarding service, including clearer language, improved UI fixes to images, and more.

Tesla has been making a lot of positive updates to the Service-related sections of the app lately, and we’re happy to see these coming rapid-fire. Tesla Service is now easier to use and understand. In the previous app update, Tesla also added the ability to pull down to update the service screens.
