Elon has said various times that Tesla is not a car company, but rather an AI company. Tesla is using AI to solve problems such as auto high beams, auto wipers and of course FSD. Tesla's tango with AI explains its recent move into robotics.
Solving FSD is just the beginning. We're likely to see Tesla enter additional fields that rely heavily on AI. Tesla will be able to take everything they've learned in the world of artificial intelligence and apply it to a completely new product or even a new field, similar to what they're doing with NeuraLink.
Tesla to look into adding AI-based HVAC
Elon has previously talked about how he would love for Tesla to develop air conditioning systems. Elon believes Tesla can make them much more efficient than they are today, but Tesla just doesn't have the resources to enter another field right now. The use of air conditioning around the world currently accounts for 10% of global electricity usage, according to IEA.
Tesla may now be looking to introduce AI to Tesla HVAC systems. Twitter user @coffeetabletsla asked Elon if Tesla could develop a neural network similar to Deep Rain that's used for windshield wipers, but instead use it to improve air conditioning. It could monitor when to turn the AC on/off, when to circulate air versus bringing in fresh outside air and take into account various factors such as current air quality, traffic and dirt roads.
In response, Elon gave his typical “Ok" answer, which has usually meant that Tesla is already working on a similar feature or that Elon is genuinely intrigued by the idea and will have Tesla engineers evaluate its feasibility.
Given Elon's fascination with air conditioning and wanting to reduce the world's energy footprint, this could be Tesla's first entry into the HVAC industry.
This conversation started on Twitter when the official Tesla account tweeted “can we all just agree that pumping out carbon monoxide, carbon dioxide, particulate matter, nitrogen oxide and sulphur dioxide from cars on all the streets around the world is maybe a bad idea".
Elon replied to the Tesla account with “in close traffic, poisonous gas spewing from the car in front of you goes straight into your AC intake." A fair point. We're just hurting ourselves. He then snarkily added that “Good thing gas/diesel carmakers didn't cheat on their emissions or we'd be in real trouble."
Air quality is also something Elon has shown interest in before. In fact, Teslas in China show the Air Quality Index right next to the temperature near the top portion of the car's screen.
In close traffic, poisonous gas spewing from the car in front of you goes straight into your AC intake. Good thing gas/diesel carmakers didn't cheat on their emissions or we'd be in real trouble ?
Teslas currently have an Auto AC button that determines when to activate the air conditioning system, although it's likely to be similar to other manufacturers where it compares the indoor and outdoor temperatures along with the relative humidity of each environment.
By adding AI to air conditioning not only can Tesla reduce its energy usage, resulting in longer range for your Tesla, but it could also give you cleaner air to breathe. Your Tesla can give you fresh air when you're driving alone on the road, and automatically switch to recirculated air when you're close to other cars.
This is just another example of how Tesla is redefining cars and improving the world we live in.

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.
