Musk says Tesla is ready to release FSD 12.4 next week
Not a Tesla App
Less than two weeks since its last FSD update, Tesla is getting ready to release FSD v12.4, with CEO Elon Musk hinting at significant improvements. The current version, 12.3.6, introduced Autopark and High Fidelity Park Assist for vehicles equipped with ultrasonic sensors in the U.S. and Canada, along with minor fixes for FSD.
Just an hour ago, Musk shed some light on Tesla's next FSD update. Through his X account, Musk teased the imminent release of v12.4, stating, "Probably start rolling out 12.4 next week." Moreover, he provided insights into the development process and the features users can expect in the upcoming 12.4 version, as well as v12.5 and v12.6.
What to Expect in FSD v12.4
Musk says that FSD 12.4 has extensive retraining of AI models that particularly focuses on refining the comfort of passengers by addressing concerns around abrupt acceleration or braking. Musk previously commented on the next versions of FSD saying that FSD v12.4 and 12.5 would be major improvements, and while v12.4 may be a major step forward, it looks like its main focus will be on being more natural and smoother.
"Probably start rolling out 12.4 next week."
FSD v12.5 and v12.6 to Handle More Complex Scenarios
Looking ahead, Tesla is already laying the groundwork for future updates according to Musk. The CEO previously stated that Tesla is constantly working on FSD updates that are three to six months ahead of what’s in production, so they have a good idea of what the software will be able to handle in the future.
Today on X, Musk said that there's ongoing testing for FSD versions 12.5 and 12.6, which involves tackling complex scenarios. Musk says this includes navigating narrow, one-way roads and handling unexpected road closures, requiring the vehicle to reverse and find alternate routes.
Actually Smart Summon in v12.5?
Tesla’s Autopilot lead, Ashok Elluswamy, previously talked about how FSD would gain the ability to go in reverse when Tesla is ready to release Actually Smart Summon. If the ability to reverse is still tied to some of the abilities of Actually Smart Summon, then, it’s possible we may see Tesla’s better summon implementation in version 12.5 or 12.6.
Vehicles to be Able to Communicate with Fleet
Musk also gives us some insight into vehicle communication, saying vehicles will need to be able to communicate with the fleet so that you "don't get a whole bunch of Teslas stuck down a road."
Instead of vehicle-to-vehicle communication, Tesla will likely have vehicles report back to the "mothership," where Tesla can aggregate data and report it to nearby vehicles. This is similar to how vehicles report traffic today, instead of talking directly to each other.
Spending on AI
Tesla's commitment to advancing its AI capabilities is evident through its substantial investments. Musk recently emphasized the company's dedication to spending around $10 billion throughout 2024 on training and inference AI. Musk said that any company that isn’t spending billions on AI this year just won’t be able to compete.
Expansion of FSD
Tesla appears ready to start the expansion of FSD, and it looks like China may be up first. Musk's recent visit to Beijing to discuss a potential FSD rollout and data sharing shows that Tesla is ready and serious about FSD's expansion.
While FSD's rollout in China appears promising, Musk remains cautiously optimistic about expanding into other markets. He believes that FSD v12 is ready for supervised FSD in left-hand drive (LHD) countries, while right-hand drive (RHD) markets like the UK and Australia may require additional time.

We’ve known for a while now that Tesla has been using a custom build of FSD to allow its newly produced vehicles at Giga Texas and Fremont to autonomously navigate themselves from the production line to the outbound delivery lot.
While we knew they were using a custom build of what was likely FSD Unsupervised, thanks to a recent post from Tesla AI on X, this has now been confirmed. Tesla has also confirmed it has accrued over 50,000 driverless miles, totalled from vehicles autonomously driving themselves to delivery lots.

For most of Tesla’s vehicles - that’s a 1.4-mile trip that is shared with pedestrians, cars, trucks, and construction equipment. You can see in the video that the Teslas are navigating public roadways and encountering real human drivers.
That’s great news, especially since many were wondering whether Tesla would secure the necessary approvals in time to launch their Robotaxi network in June.
Increased Confidence
Following Tesla’s post to X, Musk followed up by saying that when Tesla launches FSD Unsupervised soon, it will be the first time there will be a generalized, pure AI solution to autonomy. Tesla and several executives continue to post more content about autonomy and the Robotaxi network, leading us to believe they’re feeling confident in the June launch.

Back when Tesla initially announced the autonomous travel of its vehicles from production to loading lots, they mentioned that the Cybertruck was the only vehicle at Giga Texas not receiving that same treatment.
Now, that’s changed - Cybertruck is now also navigating through the Cybertunnel to make its way from the factory directly to the loading docks, all on Unsupervised FSD. And that’s making us even more excited, especially because Tesla was supposed to launch an FSD Update for the Cybertruck a little while ago - but it hasn’t made it to production yet. This update is set to bring Start FSD from Park, as well as Actually Smart Summon - bringing the Cybertruck to feature parity with Tesla’s other AI4 vehicles.

Now that Tesla is confidently using a build of Unsupervised FSD to navigate the tight confines of the tunnel and park, we’re pretty sure that Tesla will likely launch the expected FSD update in the near future.
FSD Update Soon?
It’s been a while since any FSD hardware variant has received an FSD update. It appears that Tesla has been focused on Unsupervised FSD and launching FSD outside of North America.
It seems like we may get a new FSD update soon, and we don’t believe it’ll be just for the Cybertruck. Those who have the opportunity to sign up for Tesla’s new Early Access program will likely be some of the first recipients to receive the FSD update, so stay tuned.
Lars Moravvy, Tesla's Vice President of Vehicle Engineering, recently took to X to pose a question to the community: “Let's make Teslas better… what do you all want for 2026?”
The question absolutely took off, and there were tons of fantastic suggestions about what Tesla owners would love to see from their vehicles in the future.
There were more than 12k suggestions, so let's take a look at some of the most popular feature requests.
Top Suggestions
CyberSUV - A classically styled SUV with a stainless steel exterior.
Faster Charging & Better Charge Curves - Tesla vehicles start off with fast charging speeds, but usually taper off quickly in comparison to other brands. This is especially true when compared to some Chinese brands, which sustain 500 kW charging at up to 70% state of charge. Let's get improved charging speeds on Teslas as well, especially with the 500 kW Superchargers coming in Q3.
450mi / 500mi range vehicles - Lots of customers want longer range vehicles, even though Tesla's analysis says the 300-mile range is ideal for 90% of its customer base. Range really does matter - especially for customers in more rural locations or those who choose to tow or haul with their vehicles.
Ambient Lighting Reacts to Music - This one is pretty straightforward, and it's surprising we don't already have this feature. Having basic integration with the currently playing audio is a neat feature, and really helps to make the entire experience even more seamless and premium.
Refresh Model 3 Signal Stalk Retrofit - Some people really love their signal stalks. While there aren't retrofits available just yet, we do recommend the Enhauto Stalks. For those who want an official retrofit, there is now some hope - Lars responded and said he'll try.
Lumbar Support in the Profile - Right now, lumbar support is the only seat item not saved to the Tesla Profile. This may change soon, as Lars followed up and mentioned that there are a few technical issues preventing it, but Tesla could make it work with some of their magic.
Model 3 Track Pack - The Model S has an exclusive Track Pack as a post-factory retrofit offered by Tesla, including premium brakes, tires, and wheels. The Refreshed Model 3 Performance is a killer track vehicle - but getting real track support from Tesla would be a game-changer for those who love to race.
Some of Our Favorites
Sentry Mode Improvements - Several users suggested adding B-pillar recording to Sentry Mode. And it looks like Tesla has already been working on this, and it'll be available in the upcoming 2025 Spring Update, which will be update 2025.14. Unfortunately, it'll be limited to what appears to be HW4 vehicles due to the additional processing.
Massaging Seats - A touch of luxury for Tesla's most premium models would be nice. Many other luxury brands already offer massaging seats so it’d help keep the Model S on par with these brands. Edit: Corrected that the Model S has never come with massaging seats.
Powershare for More Vehicles - Powershare is a fantastic feature, and bringing it to every Tesla is a must, especially as many other brands, including Ford, Kia, and Hyundai, offer either Vehicle to Load or Vehicle to Home capabilities as an option on their EVs. Tesla recently introduced the Mobile Connector with Powershare capabilities and an Outlet Adapter, but it's still exclusive to the Cybertruck for now.
Starlink Integration - Tesla currently uses cell networks for connectivity, which can sometimes be spotty. Starlink is a clear, high-tech solution that could provide data to vehicles when they have a clear line of sight to the sky.
Grok in Vehicles - Musk has already confirmed that Tesla will be integrating Grok into Tesla vehicles. We expected it to be included in Tesla's Spring Update, but it looks like they'll need a little bit longer. One of the lead xAI/Grok developers mentioned the request with a wink emoji, so it's clear it’s a feature that Tesla and xAI are actively working on. The way users will be able to naturally talk to AI will be game-changing for many users who are used to driving alone.
There was a lot of positivity in the comments, as well as a ton of interesting requests that could eventually be implemented in Tesla vehicles. Lars also responded to quite a few of the comments, which was nice to see.
While nothing is certain, some of these popular requests may come in a future update, while others may need hardware changes if Tesla wants to implement them.
2026 may seem far away, but there's already plenty of coming this year with a cheaper vehicle and the launch of the Robotaxi network.
