Tesla FSD Beta 11.4.8 Release Notes Explained: Faster Decision Making, Improved Park Assist and More

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.

Tesla is Creating a Voice Assistant to Replace Voice Commands [Example of Voice]

It looks like Tesla may soon be replacing its archaic voice commands with something much more useful — a voice assistant.

Greentheonly, who often takes deep dives into Tesla software by decompiling the firmware and looking for changes, has now found the early integration of a voice assistant.

Voice Assistant Already Available in China

Tesla has already replaced its voice commands in China with a voice assistant that can not only control certain aspects of the vehicle using more natural language but can also answer common knowledge questions such as the current weather, stock quotes and more (video below).

Tesla Creating Own Assistant

According to Green's findings, it looks like Tesla may be rolling its own solution instead of integrating something like Amazon Alexa like Rivian has. Tesla created their own solution in China by using some of their own technology and several existing software solutions. However, some of them are only available in China so they don’t scale to support additional regions.

Grōk

The first thought that comes to mind is Tesla leaning on AI efforts by Grōk and xAI, which could help it support common knowledge questions and search the web for answers. However, that only gets Tesla partly there, as Alexa and Google Assistant already support a large ecosystem, one that may not be available if Tesla creates their own voice assistant. With Tesla’s solution, a driver may be limited to what devices they can control through the voice assistant, at least initially. Either way, just a more natural way to activate certain vehicle solutions will be an improvement over what’s available today. The ability to ask the assistant common questions will be the icing on top.

Wake Word

According to Green, the source code hinted at the voice assistant using a wake word, which would replace the need to press the scroll wheel on the steering wheel. Tesla has begun to use the left scroll wheel button for additional things lately such as wiper controls and a multi-function mode, so this may fit in with their plan.

It’s fun to speculate what the wake word would be or whether Tesla would add the ability to create your own. It could be something as simple as ‘Hey, Tesla’, ‘Grok’, or something more humorous as Tesla has a knack for. Unfortunately, there weren't any hints on what the actual wake word would be, but being able to set a destination, play a specific song or ask the assistant for the weather will be a much-needed improvement.

Supported Models

It's not clear which models Tesla would support a voice assistant, but with the release of software v12 with update 2024.14.3, Tesla is starting to leave more features out of older Intel-based vehicles. While a voice assistant may not necessarily be computationally heavy, it may depend on Tesla's implementation and whether voice commands are transcribed on device or carried over the internet for transcription.

Voice Model

In the software, there are references to Microsoft's text-to-speech technology and specifically to a voice named “Jenny Neutral.”

The “Jenny Neutral” voice seems like an acceptable voice, bringing a natural-sounding voice to Tesla's voice assistant, although it doesn't differ much from what you find on other assistants. You can view an example of Microsoft’s “Jenny Neutral” voice in the video below.

Tesla has been more mindful lately about adding information for unreleased features to its software to help prevent leaks, so by the time something like this is found by Green, it usually doesn't take long before it becomes available, although this could also make for an exciting Christmas present.

Tesla Hints at Support for Amazon Music Streaming in Update 2024.14.3

Thanks to Tesla hacker Greentheonly, it looks like Tesla will soon offer a native experience for Amazon Music in their cars.

Green decompiled Tesla's latest update, version 2024.14.3, and found references to Amazon's music service, Amazo Music.

In this same update, Tesla added Audible playback, the audiobook service Amazon bought back in 2008.

For Tesla to add support for these music services, they need to have access to APIs that are provided by the music provider. Like everything else, there's likely a deal Tesla and Amazon struck, not only for Audible which was released in this update, but also for Amazon's other services. Given that there are already references to Amazon Music in 2024.14.3, it may not be long before we see the service launch in an upcoming update.

Prime Video 

Although Green doesn't mention any references to Amazon Prime Video specifically, it's possible we may see that service added as well. Tesla's Theater "apps," are essentially links to a browser without the user interface, so detecting references for Amazon Prime Video would be more difficult to discover in Tesla's source code. Since Tesla already implemented Audible and there are now hints of Amazon Music, it’s looking like we may see support for Amazon Prime Video as well.

Not the First Time Tesla Has Hinted at Amazon Music

Back in 2020, we saw Tesla add hints of supporting Amazon Music, although the code was scrapped in a later revision. The same source code in 2020 had references to Pandora, Audible and Apple Music. Since then we've seen Tesla add support for two of those services, with Pandora being the only one left out.

Top Music Services in the World

According to Exploding Topics, Amazon Music is the fourth most popular music service in the world as of February 2024 with a 13.3% share of the market. Number one is not surprisingly Spotify, with Apple Music and Tencent (Chinese music service) taking the second and third spots respectively.

Who Will Get Access

Amazon Music will actually be a great addition, especially if you don't pay for a separate music service like Spotify or Apple Music, but have Amazon Prime.

In the U.S., LiveOne, previously known as Slacker is the default music service that comes for free with Tesla — although Premium Connectivity is still required to listen while driving. Tesla simply calls it "Streaming" in the vehicle since this was named before Tesla had support for multiple music services. Tesla currently supports LiveOne, Spotify, Apple Music, TIDAL, TuneIn and SiriusXM on the Model S and Model X.

Although LiveOne is free, it has several limitations on audio quality, music curation and song selection. It also doesn’t allow you to jump to certain parts of a song.

Amazon Music offers a much more robust solution, so it's expected to be a nice upgrade for owners who already have access to the music service.

If you subscribe to Amazon Prime and get the free version of Amazon Music, it's expected that you'll have access to it in your vehicle without any additional charges, just like you do on your phone and other devices.

Amazon also offers a premium plan for $10 per month that includes higher-quality audio and access to a larger music library. However, we don't believe the premium plan will be required to use the service in the vehicle.

Tesla update 2024.14.3 is currently rolling out to customers around the world, although it could be several weeks before most customers have access.
