Tesla has released FSD Beta 11.4.1 update to employees, featuring significant architectural improvements that Elon Musk says should arguably qualify it as version 12.0. This update is more than just bug fixes. It contians new release notes, which likely build on top of the features from FSD Beta 11.4 version, which never made it beyond employee testing. In includes many enhancements that should make driving smoother and safer than ever.
Enhanced Control and Smoothness in Driving
The FSD Beta 11.4.1 update offers improved control through turns and overall smoothness by refining various aspects of lanes, lines, road edges, and restricted spaces. This results in a significant boost in the perception of lanes in city streets, forks, merges, and turns, thanks to an expanded and cleaner training set and an updated lane guidance module.
Boosted Perception and Detection Capabilities
With the addition of lane-guidance inputs to the Occupancy Network, the update delivers improved detections of long-range roadway features, reducing false negative median detections by 16%. Additionally, the update enhances motorbike recall by 8% and vehicle detection precision, making the system more robust against variances in vision frame rate.
Assertiveness and Lane Management Improvements
The FSD Beta 11.4.1 update showcases improvements in Tesla's assertiveness when dealing with crossing pedestrians, allowing the vehicle to cross safely before the pedestrian when possible. In addition, interventions caused by other cars cutting into the Tesla's lane have been reduced by 43% thanks to a new framework that anticipates such actions and proactively adjusts the car's position.
Speculating on the Release Date for Public Testers
The release date for FSD Beta 11.4.1 to public testers remains uncertain. Since version 11.4 has been in testing with some employees for three weeks, and 11.4.1 is a revision, we could see the update roll out to select public testers within the next few days. However, Tesla could also wait for another revision before releasing it more widely, depending on the success of the current testing phase. It's also unlikely this version will be given out as a one-month free trial.
An Unusual Version Number in Tesla's Update History
The choice of version number for the FSD Beta 11.4.1 is peculiar, but it isn't the first time Tesla has used unconventional version numbers this year. It remains unclear whether this update includes any features beyond those in the 2023.6 branch. Other unusual releases include 2022.45, 2023.2, and 2023.6, which deviate from Tesla's typical version naming.
Additional Features in FSD Beta 11.4.1
Even if FSD Beta 11.4.1 only includes features from the 2023.6 update, it will still be a significant upgrade for current testers on the 2022.45 FSD branch who are missing features from the 2023.2 and 2023.6 updates. Some notable features introduced in these updates include Sentry Mode Lighting improvements, improvements to Apple Music and more.
This FSD Beta update is also expected to include features from Beta 11.4, which includes enhanced navigation planning, improved vehicle handling in challenging weather conditions, better speed control in parking lots and during lane changes.
Tesla's FSD Beta 11.4.1 represents an exciting expansion of the features introduced in version 11.4 and subsequent updates. With major architectural improvements, enhanced control and smoothness, advanced perception and detection capabilities, and additional features from updates 2023.2 and 2023.6, this upgrade promises a significant step forward in Tesla's Full Self-Driving technology.
Back in 2021, while Giga Berlin was still undergoing construction, Elon Musk said that he wanted to fill the factory with graffiti artwork. Just months later, Tesla posted a submission link to find local artists for the project.
It remained relatively quiet for about two years until Musk resurfaced with a post congratulating the team on their progress—and revealing that the factory’s concrete would be entirely covered in art. By 2023, that vision was already taking shape. Tesla began by collaborating with local artists, who created much of the artwork seen in the 2023 image above.

As expected from Tesla, they didn’t just hire a group of artists to paint and scale the walls. True to their ethos of autonomy, robotics, and innovation, they sought a more futuristic approach. The local crews couldn’t work fast enough or cover enough ground, so Tesla did what it does best—push the boundaries of technology.
Covering an entire factory in art is a massive undertaking, especially when that factory spans 740 acres (1.2 sq mi / 3 km²). With such an immense canvas, Tesla needed a high-tech solution.
Enter a graffiti start-up that had developed a robotic muralist. Tesla partnered with the company, sourcing digital artwork from independent artists while also commissioning pieces from its in-house creative team. Armed with this collection, the robot meticulously printed the artwork directly onto the factory’s concrete, turning Gigafactory Berlin-Brandenburg into a futuristic masterpiece.
The Robot
Not a Tesla App
This ingenious little robot is equipped with a precision printhead and a sophisticated lifting mechanism. It moves using two kevlar cables that allow it to glide up, down, left, and right while a pair of propellers generates downforce to keep it steady against the wall.
The printhead itself is capable of painting approximately 10 million tiny dots per wall, adding up to a staggering 300 million dots just for the west-facing side of Giga Berlin. Each mural features five distinct colors, and the robot carries 12 cans of paint, ensuring it can keep working for extended periods without interruption.
Check out the video below to see the robot action, along with mesmerizing time-lapse footage of the printing process. It’s an exciting glimpse into how Tesla is blending technology and creativity at Giga Berlin—and we can’t wait to see what’s next.
With FSD V13.2.6 continuing to make its way to AI4 vehicles, Tesla has been on a streak with minor FSD improvements since the launch of FSD V13 just a little over two months ago.
FSD V13 brought a new slate of features, including Start FSD from Park, Reverse, and Park at Destination. It also introduced full-resolution video input using the AI4 cameras at 36hz and made use of the new Cortex supercomputer to get faster and more accurate decision-making.
So, what’s next with FSD V14? Tesla gave us a sneak peek at what’s next for FSD.
FSD V14
The standout feature of FSD V14 will be auto-regressive transformers. While that’s a complex term for those unfamiliar with AI or machine learning, we’ll break it down.
Auto-Regressive
An auto-regressive transformer processes sequential data in time, using that information to predict future elements based on previous ones. Imagine completing a sentence: You use the words already written to guess what comes next. This process isn't just about filling in the blank; it's about understanding the flow of the sentence and anticipating the speaker's intent.
FSD could analyze a sequence of camera images to identify pedestrians and predict their likely path based on their current movement and surrounding context. The system's auto-regressive nature allows it to learn from past sequences and improve its predictions over time, adapting to different driving scenarios.
Today, FSD reacts to what it sees, but soon it’ll be able to anticipate what will help, much like humans.
Transformers
The second part of that term is transformer, which is a component used to understand the relationships of elements inside a time sequence. It identifies which parts of the input are most crucial for making accurate predictions, allowing the system to prioritize information much like a human would. Think of it as weighing different pieces of evidence to arrive at a conclusion. For example, a transformer might recognize that a blinking turn signal is more important than the color of the car when predicting a lane change.
Putting It Together
Putting all that together, Tesla’s use of auto-regressive transformers means they’ll be working on how FSD can predict the plans and paths of the world around it. This will improve FSD’s already powerful perception and allow it to predict how other vehicles and vulnerable road users (VRUs) will behave.
What it all comes down to is that FSD will be able to make better decisions and plan its paths by making more informed, human-like decisions. That will be a big step towards improving V13 - which already has some very effective decision-making.
Larger Model and Context Size
Ashok Elluswamy (Tesla’s VP of AI) stated that FSD V14 will see larger model and context sizes in FSD V14, which coincidentally are listed in the upcoming improvements section of FSD V13.2.6. If we compare what Ashok said to what’s listed in the upcoming features section, the model and context sizes should grow by 3x.
Interestingly, Ashok says that AI4’s memory limits context size. Context is essentially the history of what the vehicle remembers, which is used for future decisions. Since this information is stored in memory, it’ll always be limited by memory, but it’s worth noting that Ashok mentioned that Tesla is restricted by the memory in the AI4 computer.
Leverage Audio Input
Tesla is already gathering audio data in existing FSD versions so that it can start training models with audio as well, truly making FSD more human-like. According to Ashok, FSD V14 will be the first version to take advantage of audio input for FSD driving. This will primarily be used for detecting emergency vehicles, but we can see this expanding to other sounds that help humans adjust their driving, such as car crashes, loud noises, honking, etc. At the very least, FSD could be more cautious when hearing a noise that matches an accident or vehicle honking.
FSD V14 Release Date
We haven’t heard from Elon Musk or Ashok Elluswamy about when FSD V14 will arrive. Ashok previously stated that FSD V13.4 would see audio inputs being used, but at Tesla’s earnings call, Tesla said that audio input would become relevant in V14, making it seem like Tesla may scrap V13.4 for V14.
Since Tesla is planning to launch their Robotaxi network in Texas this June, which is just four months away, FSD V14 may be the version used for its autonomous taxi fleet.
