One of the exciting new features of Tesla update 2024.14 is the improved media player for the Model 3 and Model Y.
Tesla's media player has gone through some drastic changes over the years, but this appears to be the best revision yet.
The previous media player had four states... yes, four. It made for a confusing experience, even for owners who used the car every day.
The four states included:
The "default" state included a small player closest to the driver with some of the most used buttons
The second state was the enlarged view when you dragged up on the media player that revealed additional buttons such as shuffle and search
There was also its minimized state, which placed the music player’s icon in the dock and led to confusion
And lastly, if you had a music service open fully on the right part of the screen AND minimized the media player, then the player would hop over to the top of the larger music panel on the right.
It created an inconsistent experience and all of the players had their downsides. There just wasn’t a solution that worked all of the time. Thankfully the new music player addresses most of these issues.

What’s New
The first thing Tesla did was reduce the number of states essentially down to two. You have a regular media player and a minimized player. You don't have to drag up on the player to access the shuffle or search functions and you can’t “lose” the player by minimizing it to the dock anymore.
Correction: When you minimize Tesla’s audio player and have Spotify or another music app open, the player controls will still shift to the top of the music app.
One-Tap Access to Shuffle, Repeat and Search
What Tesla did was move all of the crucial media functions from the previous larger player directly to the main player. This now gives you one-tap access to functions like shuffle, repeat, search, playback speed, audio levels, and search.
Not only were these functions hard to access before, but they were hidden underneath the player, making discovery for new owners difficult.
Improved Progress Bar
The progress bar on the previous player was difficult to see since it was just a slim line at the bottom of the player.
The new player has a thicker progress bar that separates the top portion of the player, which houses the album art, song title, and a couple of functions, and the bottom portion, which contains more controls. Tesla also added a circle to the progress bar, making it more obvious you can not only scrub through the media but also lets you easily see your current spot.
Accessing More Functions
More music player options open to the right
Not a Tesla App
Since the larger media player was removed, so was some of the functionality that it included. All the important items were moved to the main media player such as audio settings and search, however, the other functionality such as access to Favorites, Sources, Recent Songs, and Next, was moved to the larger music app.
If you tap on the new music player, it’ll open up the current music app on the right side that includes music controls, as well as access to your favorites, music sources, upcoming songs and more.
This is also the only way to view the elapsed and remaining times for the current selection, which is useful for longer median such as audiobooks or podcasts.
New Minimized Player
Although the music player doesn't minimize to the dock, it does feature a minimalist version that docks to the bottom of the screen.
When you slide down on the audio player, it'll be reduced to a simple "one-line" player. It simply shows a music icon, the name of the title being played, and an arrow showing you the player can be made larger. There is no longer a gray music icon that appears in the dock when the player is in its “minimized” state.

Modern UI
The player itself also looks more modern, it now features a translucent background, instead of a solid color like before. The new background lets vehicle animations subtly shine through, a lot like the effects used on modern operating systems.
What Models Will Support It
According to Tesla’s social media post on X, the ‘Visual updates’ in update 2024.14 are limited to AMD Ryzen-based Model 3 and Model Y vehicles, meaning only vehicles manufactured after about 2022+. The exact timeline depends on your vehicle and region, but you can check to see which processor your vehicle includes by navigating to Controls > Software > Additional Vehicle Information.

Will We See Intel Atom Support?
The new music player isn’t doing anything crazy in this latest iteration. We believe we'll see this updated player come to Intel Atom vehicles eventually. The Cybertruck already includes the new media player, among the other design changes, so when Tesla said only for “Model 3/Y with AMD chip” on X, they likely meant in this specific update.
There's nothing that’s more computationally intensive about this new player except for maybe the translucent background, however, that’s already being done on Intel-based vehicles for some of the navigation modules. There isn’t anything new that the slower Intel processor couldn't handle.
It’s in Tesla’s best interest to keep a common interface between vehicles. Tesla wouldn't want to drastically change the way a common item like the "radio" works between different Model 3 and Model Y years if they didn't have to. That would complicate issues with service and documentation. Tesla wants owners to have the same UI as much as possible, so we there’s a good chance that we’ll see the new media player apply to Intel in the future.
Hopefully, in an upcoming update, Intel owners will receive this streamlined music player. Update 2024.14 is currently rolling out slowly to some vehicles.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.

At the 2025 Consumer Electronics Show, Nvidia showed off its new consumer graphics cards, home-scale compute machines, and commercial AI offerings. One of these offerings included the new Nvidia Cosmos training system.
Nvidia is a close partner of Tesla - in fact, they produce and supply the GPUs that Tesla uses to train FSD - the H100s and soon-to-be H200s, located at the new Cortex Supercomputing Cluster at Giga Texas. Nvidia will also challenge Tesla’s lead in developing and deploying synthetic training data for an autonomous driving system - something Tesla is already doing.
However, this is far more important for other manufacturers. We’re going to take a look at what Nvidia is offering and how it compares to what Tesla is already doing. We’ve done a few deep dives into how Tesla’s FSD works, how Tesla streamlines FSD, and, more recently, how they optimize FSD. If you want to get familiar with a bit of the lingo and the background knowledge, we recommend reading those articles before continuing, but we’ll do our best to explain how all this synthetic data works.
Nvidia Cosmos
Nvidia’s Cosmos is a generative AI model created to accelerate the development of physical AI systems, including robots and autonomous vehicles. Remember - Tesla’s FSD is also the same software that powers their humanoid robot, Optimus. Nvidia is aiming to tackle physical, real-world deployments of AI anywhere from your home, your street, or your workplace, just like Tesla.
Cosmos is a physics-aware engine that learns from real-world video and builds simulated video inputs. It tokenizes data to help AI systems learn quicker, all based on the video that is input into the system. Sound familiar? That’s exactly how FSD learns as well.
Cosmos also has the capability to do sensor-fused simulations. That means it can take multiple input sources - video, LiDAR, audio, or whatever else the user intends, and fuse them together into a single-world simulation for your AI model to learn from. This helps train, test, and validate autonomous vehicle behavior in a safe, synthetic format while also providing a massive breadth of data.
Data Scaling
Of course, Cosmos itself still requires video input - the more video you feed it, the more simulations it can generate and run. Data scaling is a necessity for AI applications, as you’ll need to feed it an infinite amount of data to build an infinite amount of scenarios for it to train itself on.
Synthetic data also has a problem - is it real? Can it predict real-world situations? In early 2024, Elon Musk commented on this problem, noting that data scales infinitely both in the real world and in simulated data. A better way to gather testing data is through real-world data. After all, no AI can predict the real world just yet - in fact, that’s an excellent quantum computing problem that the brightest minds are working on.
Yun-Ta Tsai, an engineer at Tesla’s AI team, also mentioned that writing code or generating scenarios doesn’t cover what even the wildest AI hallucinations might come up with. There are lots of optical phenomena and real-world situations that don’t necessarily make sense in the rigid training sets that AI would develop, so real-world data is absolutely essential to build a system that can actually train a useful real-world AI.
Tesla has billions of miles of real-world video that can be used for training, according to Tesla’s Social Media Team Lead Viv. This much data is essential because even today, FSD encounters “edge cases” that can confuse it, slow it down, or render it incapable of continuing, throwing up the dreaded red hands telling the user to take over.
Cosmos was trained on approximately 20 million hours of footage, including human activities like walking and manipulating objects. On the other hand, Tesla’s fleet gathers approximately 2,380 recorded minutes of real-world video per minute. Every 140 hours - just shy of 6 days - Tesla’s fleet gathers 20 million hours of footage. That was a little bit of back-of-the-napkin math, calculated at 60 mph as the average speed.
Generative Worlds
Both Tesla’s FSD and Nvidia’s Cosmos can generate highly realistic, physics-based worlds. These worlds are life-like environments and simulate the movement of people and traffic and the real-life position of obstacles and objects, including curbs, fences, buildings, and other objects.
Tesla uses a combination of real-world data and synthetic data, but the combination of data is heavily weighted to real-world data. Meanwhile, companies who use Cosmos will be weighting their data heavily towards synthetically created situations, drastically limiting what kind of cases they may see in their training datasets.
As such, while generative worlds may be useful to validate an AI quickly, we would argue that these worlds aren’t as useful as real-world data to do the training of an AI.
Overall, Cosmos is an exciting step - others are clearly following in Tesla’s footsteps, but they’re extremely far behind in real-world data. Tesla has built a massive first-mover advantage in AI and autonomy, and others are now playing catch-up.
We’re excited to see how Tesla’s future deployment of its Dojo Supercomputer for Data Labelling adds to its pre-existing lead, and how Cortex will be able to expand, as well as what competitors are going to be bringing to the table. After all, competition breeds innovation - and that’s how Tesla innovated in the EV space to begin with.
