FSD Beta to go out to everyone in about the next month
Not a Tesla App
You get FSD! You Get FSD! Everybody gets FSD! For those waiting, Elon Musk's Full Self Driving announcement may have felt like being in the studio audience when Oprah gave everyone a car. People in the audience screamed, cried, and hugged as Oprah continued to chant, "everybody gets a car."
Musk, who can also be a showman, could've used the pop-culture classic meme. But instead, he casually mentioned that all FSD subscribers would be able to use the program by the end of the year. During the quarter three earnings call, Tesla's CEO told listeners, "So, anyone who has ordered a full self-driving Beta — full self-driving, will have access to the FSD Beta program this year [in North America]. Probably about a month from now."
Tesla's Q3 Earnings Call
FSD version 10.69.3 is due any day, and Musk has publicly stated his confidence and excitement with the next update. The 51-year-old believes that FSD and, eventually, fully autonomous vehicles will prevent countless injuries and save thousands of lives by making the roads safer. He is now seeing that in the data that Tesla is collecting. "So, the safety that we're seeing when the car is in FSD mode is actually significantly greater than the safety we're seeing when it is not, which is a key threshold for going to a wide Beta," said Musk.
On A.I. Day 2022, Tesla's director of the Autopilot program Ashok Elluswamy, said, "FSD beta software is quite capable of driving the car. It should be able to navigate from parking lot to parking lot, city street driving, stopping for traffic lights and stops signs, negotiating with objects at intersections, making turns and so on." Several team members who spoke at the event raved about the improvements of using an integrated stack. That means one code base that includes everything the car needs to operate all aspects of FSD.
Musk has been using the single-stack version for months. He told investors that he just used it. "When I came to Giga, Texas, from Brent's house, I never touched any of the controls on the way here." He said that all subscribers to the FSD package will soon experience this technology. "The car will be able to take you from your home to your work, your friend's house, to the grocery store without you touching the wheel. So, it's looking very good."
Telsa executives have used the term supervised FSD or supervised autonomy when discussing how the technology has advanced. This means that the driver must still pay attention and be ready to intervene at any time. "We're not saying that that's quite ready to have no one behind the wheel. It's just that you will almost never have to touch the control, vehicle controllers," said Musk.
Safer Than a Human
That may soon be changing. Musk says the company is very close, and it will soon be able to challenge the regulatory bodies and prove that FSD is safer than human driving. "Certainly, without a question whatsoever in my mind, next year. I think we'll also have enough data next year to be able to show to regulators that the car is safer than the average human."
Now we need a Musk meme. You get FSD! Everybody gets FSD!

Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.
LFP Battery Heating
Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.
The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.
Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).
In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.
We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.
Thanks to Greentheonly for helping us understand what happened with this release and for the insight into Tesla’s processes.
