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.

Elon Musk and SpaceX have set some ambitious dates for the first Mars landing. Musk envisions launching the Starship toward Mars by late 2026—less than two years away. There won’t be any humans on board in the initial launches. Instead, Optimus will fill in for humans. Musk stated that human landings could follow as early as 2029 to 2031.
There are certain windows that make flights to Mars feasible for humans. So SpaceX is aiming for humans to be a part of the second or third Earth/Mars launch windows from now, which are 5 to 7 years away.
Tesla continues advancing Optimus, and SpaceX remains relentless. Another Starship test launch is in the books, all while maintaining their steady weekly cadence of Dragon missions to space.
Starship departs for Mars at the end of next year, carrying Optimus.
Civilization On Earth
Musk goes on to state something interesting in another post on X. He says that the key will be whether “Earth’s civilizational technology level will last long enough to ensure Mars can grow by itself, even if supply ships from Earth stop coming.”
The statement suggests two possibilities—that Earth’s civilization collapses or fails to advance enough to solve unforeseen challenges of sustaining life on Mars.
The key concern is whether humanity will remain technologically and industrially capable long enough to ensure that Mars can eventually become self-sufficient. If Earth’s civilization weakens, either due to collapse, stagnation, or regression, Mars might not get the support it needs to reach full independence—leading to the colony’s failure.
Tossing Optimus on board Starship is a smart move, instead of having smaller, single-task robots. Optimus also has the advantage of being upgradeable on Mars as long as the hardware holds up. It could be a lot like what we saw with Tesla vehicles, where the hardware was present for many years before the vehicle was capable of driving on city streets. Optimus’ capabilities will also improve over time, even if the hardware is older.
But, how does Elon Musk envision Optimus’ role on Mars?
The answer might be simple. SpaceX can leverage a fleet of Optimus robots to assemble shelters and infrastructure before humans even arrive.
Optimus is already highly capable, with precise hands adept at manipulating tools and objects. On Mars, it could construct basic habitats, set up survival systems, and even handle ice processing, water recycling, and food production.
These facilities will be absolutely essential for the first humans to comfortably settle in and begin work on expanding, maintaining, and preparing for proper human settlement.
Beyond construction, Optimus has a major advantage—it doesn’t need oxygen. Instead, mission planners would only need to monitor battery levels, wear and tear, and any potential damage.
That said, even humanoid robots face risks. Martian dust has long been an obstacle in space exploration, clogging solar panels, damaging equipment, and causing malfunctions. Tesla will need to redesign Optimus to withstand the harsh conditions. Its joints and components will need to be sealed against Mars’ relentless environment.
Starship
Mechazilla catching Starship7 Rocket Booster for the first time ever! 🚀 Incredible Achievement by @spacex
Starship, the largest rocket ever built, is immensely capable—but still in its early testing phases. SpaceX has dedicated hundreds of hours between each flight test, refining and improving with every launch. With several Super Heavy booster catches now under their belt, the next challenge is proving Starship itself can land.
Once SpaceX can launch, complete a mission, and safely land both the booster and Starship, the dream of reaching Mars may no longer seem so far-fetched.
With that, Happy 23rd Anniversary, SpaceX! We’re with you all the way as you push humanity toward the stars.

According to Chinese blog posts from earlier last week, now vetted by Reuters, Tesla intends to produce a cut-down version of the Model Y, initially for the Chinese market, sometime in 2026.
This follows the launch of Tesla’s cut-down Model 3 for Mexico, as well as news that Tesla intends to launch their new next-gen model sometime in the near future.
Cut Down, But How?
The new Model Y, internally referred to as Project E41, is designed to lower the entry price of Tesla’s popular SUV—one of the most compelling options on the market due to its size, range, and versatility, especially following the launch of the refreshed Model Y.
To achieve this, Tesla is reportedly aiming to reduce the Model Y’s total cost by nearly 20%, according to reports from China. While exact changes remain unknown, we can make informed guesses based on the cost-saving measures Tesla implemented in the scaled-down Model 3 for Mexico.
Textile Seats and Trim
One of the most noticeable changes in the cost-cut version of the Model 3 in Mexico was the removal of vegan leather throughout the interior. In its place, Tesla opted for a durable textile fabric for the seats, reducing material costs. Additionally, any Alcantara trim pieces were replaced with the same textile in various areas.
No Heated or Cooled Seats
Another major cost-cutting measure was the removal of heated and cooled seats, along with the heated steering wheel. While these feature reductions may seem minor, eliminating them reduces various things, such as electrical components, harnesses, and ductwork that are required for seat ventilation.
No Rear Screen
One of the more unexpected changes in the reduced-cost Model 3 was the removal of the rear screen, despite it being powered by the same front infotainment computer as the front display. Given that the screen functions primarily as an additional display rather than a standalone system, the cost to include it is extremely low. It’s one of those really smart additions Tesla has added that increases value for the consumer with minimal cost to Tesla.
Tesla is unlikely to redesign or modify the vehicle’s wiring harness for this change, meaning a rear screen could potentially be retrofitted later by the customer. Based on replacement part estimates, the screen likely costs Tesla between $5 and $20 per vehicle, which acts as a secondary monitor for the infotainment computer.
Ambient Lighting, Acoustic Glass, Speakers
The final set of changes also focuses on the interior. Tesla replaced the RGB-capable ambient lighting with a simpler white-only version—likely saving only a few dollars per vehicle. While this may seem like a minor and somewhat unexpected cut, it could serve as an upsell opportunity to the standard RWD variant.
Additionally, Tesla reduced the use of dual-pane acoustic glass, now limiting it to just the front windows and windshield. This change drastically cuts costs but also affects cabin noise levels. The dual-pane glass played a key role in making the refreshed Model Y noticeably quieter, so this downgrade will likely bring noise insulation closer to that of the original Model Y.
As for audio, Tesla scaled down the speaker system in the Mexican Model 3 from 17 speakers to just nine, while also removing the subwoofers and one of the audio amplifiers. While this cuts costs due to wiring and speakers, it also has a large impact on the audio quality in the vehicle.
Project E41 is Not the Next-Gen Model
It’s important to note that Project E41 is not the same as the upcoming, more affordable next-gen platform, which is internally referred to as Project Redwood. While Project E41 focuses on a reduced-cost version of the Model Y, Project Redwood is designed to test Tesla’s manufacturing capabilities, using their innovative unboxed assembly method to reduce both costs and production time. The goal is to create a vehicle that is smaller and more affordable, while also keeping it safe and capable of self-driving.
Tesla previously confirmed that they plan to unveil new models—distinct from cut-down versions of the Model 3 or Model Y—during their Q4 2024 Earnings Call. However, the executive team has been careful not to divulge too many details about the upcoming model during interviews. This suggests there may be a lot more that has yet to be unveiled.
