A user on Reddit leaked the release notes for Tesla's next FSD Beta release
darwizzy333
Tesla's most recent FSD Beta, v11.4.7.3 was released almost a month ago on October 19th, but it now looks like Tesla may be looking to release another FSD Beta update.
Release notes for an alleged subsequent version, FSD Beta 11.4.8, have surfaced on Reddit. While their authenticity isn't confirmed, the release notes use the same syntax and language Tesla typically uses. Here's a breakdown of what may be included in Tesla's next FSD release.
Update: These release notes have now been confirmed and the update is rolling out to Tesla employees for further testing. The update is version 2023.27.11.
Simplified Autopilot Activation
Single-Tap Autopilot: The update reportedly allows drivers to activate Autopilot with just one press of the stalk, instead of the current two-press method. This could make engaging and disengaging Autopilot quicker and more straightforward.
This feature, along with separate audio for passengers using the rear display recently made its way to production in update 2023.38.8, which adds some credibility to these leaked release notes. This could also mean that this version of FSD Beta may be based on a more recent production branch, instead of the current version of 2023.27, which is now starting to lag in terms of features.
Advanced Video Processing
New Video Module: A new video processing component has been introduced to improve vehicle detection, movement understanding (semantics), speed (velocity), and other attributes. This improvement means the system can process visual information more efficiently and quickly, enhancing overall performance.
Enhanced Object Detection
Better Object Detection: The system's ability to notice objects crossing its path is said to be improved by 6%. Additionally, vehicle detection has become more precise due to updated data and the new video module.
Improved Vehicle Interaction
Cut-In Vehicle Detection: The precision in detecting vehicles that cut into the Tesla's lane is reportedly improved by 15%. This is crucial for safer lane changes and merges.
Accuracy in Speed and Movement
Reduced Errors in Speed and Acceleration: The system now makes fewer errors in judging other vehicles' speed (by 3%) and acceleration (by 10%). This means a more accurate response in traffic.
Faster Decision-Making
Reduced Network Latency: The update claims to reduce the delay (latency) in the vehicle's decision-making network by 15%, allowing for quicker responses without compromising performance.
Pedestrian and Cyclist Safety
Rotation Error Reduction: There's an over 8% reduction in errors related to understanding how pedestrians and cyclists are moving or turning. This could improve interactions with these road users.
Enhanced Parking Assistance
Vision Park Assist Accuracy: The geometric accuracy of the Vision Park Assist system is improved by 16%, making parking assistance more reliable by leveraging data from hardware 4 vehicles. It appears that these improvements will apply to all vehicles without ultrasonic sensors, although it's not very clear.
Smoother Lane Changes
Lane Change Accuracy: The accuracy of lane changes in response to path blockages is improved by 10%, likely leading to smoother and safer driving in complex traffic situations.
While these updates, if true, indicate a continued effort by Tesla to refine and improve FSD Beta, Tesla also continues work on the next major release of FSD Beta, version 12. V12 is expected to be 'end-to-end' neural networks, which will be the first time that neural networks are used to control the vehicle.
It's not clear when Tesla expects to release FSD v12, which is also when Musk says FSD will graduate from its beta status. Musk recently showed off FSD v12 and its capabilities in a livestream on X.
The complete release notes that were shared on Reddit are below.
FSD Beta 11.4.8 Release Notes
-Added option to activate Autopilot with a single stalk depression, instead of two, to help simplify activation and disengagement.
-Introduced a new efficient video module to the vehicle detection, semantics, velocity, and attributes networks that allowed for increased performance at lower latency.This was achieved by creating a multi-layered, hierarchical video module that caches intermediate computations to dramatically reduce the amount of compute that happens at any particular time.
-Improved distant crossing object detections by an additional 6%, and improved the precision of vehicle detection by refreshing old datasets with better autolabeling and introducing the new video module.
-Improved the precision of cut-in vehicle detection by 15%, with additional data and the changes to the video architecture that improve performance and latency.
-Reduced vehicle velocity error by 3%, and reduced vehicle acceleration error by 10%, by improving autolabeled datasets, introducing the new video module, and aligning model training and inference more closely.
-Reduced the latency of the vehicle semantics network by 15% with the new video module architecture, at no cost to performance.
-Reduced the error of pedestrian and bicycle rotation by over 8% by leveraging object kinematics more extensively when jointly optimizing pedestrian and bicycle tracks in autolabeled datasets.
-Improved geometric accuracy of Vision Park Assist predictions by 16%, by leveraging 10x more HW4 data, tripling resolution, and increasing overall stability of measurements.
-Improved path blockage lane change accuracy by 10% due to updates to static object detection networks.

As anticipation builds for Tesla’s Robotaxi network debut in Austin, potentially just a few short weeks away, the National Highway Traffic Safety Administration (NHTSA) is turning its official eye onto Tesla. The ask? How will Tesla’s FSD handle the unpredictable realities of challenging weather?
The NHTSA Request
The NHTSA has sent a formal letter to Tesla, which was made public on May 12th, requesting detailed information about Tesla’s Robotaxi service. The NHTSA inquiry centers specifically on the safety and performance of FSD when faced with reduced visibility conditions like rain, fog, and sun glare. The request is tied to an ongoing NHTSA investigation, which was initiated in October 2023, examining Tesla’s FSD and Autopilot suite following incidents in poor visibility.
Tesla’s executives, including Elon Musk, have previously stated that the company is full steam ahead to launch Robotaxi in Austin this June. However, NHTSA’s pointed questions come even as Tesla has recently discussed its plans to work on region-specific and weather-specific FSD training.
Tesla’s executive leadership acknowledged the need to adapt the system to diverse environmental and weather conditions. Now, regulators want specifics on how Tesla intends to address environmental conditions and how that translates to operational safety for the fleet.
Request Breakdown
NHTSA’s letter outlines a need for detailed information from Tesla before the service launches and covers several key areas. We’ve broken this down into various sections below:
Deployment Scale
NHTSA is looking for the exact number of vehicles and models that will be part of the initial Austin fleet, and what the projected service availability times would be for said fleet. Tesla has previously said it’d launch with 10-20 Model Ys, but looks like NHTSA is looking for additional details.
Oversight
In terms of oversight, NHTSA is looking to confirm whether the Robotaxis will operate under real-time supervision of Tesla’s employees, either remotely or in-vehicle.
This is a question on our minds as well. A recent app update suggested that Tesla could have a driver in the vehicle, but it wasn’t clear whether this was referring to Tesla’s own fleet or customer-owned vehicles. The only thing we have heard officially from Tesla is that Tesla “may” use remote support, but that they were still looking into it.
Adverse Weather Capabilities
This is the meat and potatoes of the request - how will Tesla ensure safety during sun glare, fog, heavy rain, snow, or dust? What specific protocols are triggered if poor visibility is encountered mid-trip? Will the vehicle pull over or call home and cancel rides?
Sensor Technology
Surprisingly, NHTSA is looking for details regarding the vehicle the Robotaxi sensor suites and how Tesla intends to use those sensors to ensure safe operation under varied conditions. NHTSA has had previous submissions from Tesla in regard to its sensor suite and how it uses the technology, so it feels odd that they are requesting another batch - but this could be related to the use of the next generation of FSD (Unsupervised).
Compliance
Does Tesla’s FSD system adhere, either fully or partially, to established industry standards for autonomous driving? This likely refers to the NHTSA Automated Vehicles for Safety guidebook, which lays out the “L0 to L5” driver assistance vs automation system.
Future Expansion
Finally, NHTSA is looking for the timeline for enabling Robotaxi functionality on vehicles not directly owned or controlled by Tesla. Tesla has already come out and said that customer-owned vehicles wouldn’t be allowed on the robotaxi network until 2026, but obviously, NHTSA wants to hear directly from Tesla and likely has more specific questions covering a wide variety of potential issues.
These questions will likely have to be answered with considerable amounts of data and justification for the NHTSA. Once all that is done, Tesla will be in a better position to receive regulatory approval at a larger scale than just within the city of Austin or the state of Texa with the NHTSA’s backing.
Successfully addressing this letter will be the key for Unsupervised FSD moving forward, but Tesla hasn’t issued a public response to the agency’s letter, and likely won’t in a public manner. So we’ll have to wait and see how the launch of the Robotaxi network pans out next month.
After an 84-day wait since the last FSD update, Tesla has finally begun rolling out a new version of FSD V13 to its AI4-equipped vehicles. This new release, V13.2.9, is rolling out to all vehicles, including the Cybertruck.
Unfortunately, since it’s a minor point release (from V13.2.8), the release notes are the same, and Tesla hasn’t included a change log or changed what’s coming in the future.
Software Update 2025.14.6
The FSD update is rolling out with Tesla software update 2025.14.6. Interestingly, update 2025.14.6 is seeing a wider distribution and is also being made available to vehicles without FSD and outside North America. For those vehicles, this update just includes bug fixes.
TCU Fix
There’s one fix in particular that’s expected to be included in this update, according to a message from Tesla Service. In earlier 2025.14 updates, there was a bug in some vehicles that prevented some vehicles from falling asleep properly due to a Telematics Control Unit (TCU) issue. This bug caused additional battery drain since some of the vehicle’s systems remained on.
Tesla Service said they planned to include a bug fix in update 2025.14.6, but it hasn’t been confirmed whether the fix actually made it out in this release.
Early Access Users and More
FSD v13.2.9 was first rolled out to Tesla’s standard Early Access group, including well-known community members and content creators. It has also reached participants in the newer, Texas-based Early Access Program, suggesting that the update is relatively stable and may serve as a foundation for upcoming FSD releases.
Tesla could be intending to use the Texas Early Access Program to test various features, perhaps related to the upcoming Robotaxi network launch in Austin. While this is plausible, it is merely speculation, and we’ll be keeping a close eye on that group to see what exactly Tesla does.
HW3 Users
While Tesla has recently been including FSD updates for HW3 and HW4 in the same release, this update does not include any changes for HW3 users. HW3 vehicles that are receiving this update are staying on FSD V12.6.4, which means that whichever fixes this update includes they’re specific to FSD V13 or HW4.
Point Release - Not Much New
Being a point release, V13.2.9 isn’t expected to introduce any major new capabilities. Tesla hasn’t provided specific release notes detailing changes from V13.2.8.
Hopefully, Tesla has taken into account recent user feedback on V13.2.8 about lane centering and lane selection, and this update addresses some of those issues. However, early feedback is that those issues are still present.
There is always potential for a more substantial update in the near future, so keep your fingers crossed, but after such a long wait, we expected more to be included. It seems like Tesla may have felt the need to address a bug in this release instead of waiting for the next major release, which is expected to either be FSD V13.3 or FSD V14.
The fact that Software Update 2025.14.6 is going out wider than the Early Access audience suggests that Tesla is confident in this release and that it likely only includes very minor changes. We expect this update to continue going out over the coming days.
