Tesla FSD Hardware 4 Has Yet to Reach Full Potential; HW3 Support Still In Progress

Not a Tesla App

According to a post on X, Elon Musk said that Tesla has yet to unlock the full potential of AI4 – the now-renamed Hardware 4.

HW4 / AI4

AI4 currently runs Hardware 3 in emulation mode, which means it's only running about as fast as Hardware 3 can run. With just basic specs in mind, AI4’s cameras have 4-5x better overall resolution and fidelity than Hardware 3 and should be about 3-5x faster in inference capabilities. That’s a considerable increase over the baseline specs of Hardware 3.

With FSD 12.5, AI4 is running a FSD model that has a 5x increase in parameters, resulting in a smoother driving experience. Recently, Elon Musk noted that AI4 should be able to provide an additional 8x time increase in parameters. While we’re not exactly sure how the parameter metric computes vs the inference capability metric, but if we add them, it’s a 12x increase in capability.

However, Elon’s post implies that this is an 8x increase over the capacity they originally thought to have – nearly 50x faster than Hardware 3. That’s a bold claim, but could entirely be based on software optimization and not having to run Hardware 3 in emulation mode in the future, once AI4 and Hardware 3 begin to diverge.

AI4 Divergence

Divergence is still expected to be a few months away – at least not until early 2025. However, Elon confirmed that the new Supercomputer Cluster, which will run AI4 alongside Nvidia GPUs, is coming online very soon. This means that work on improving FSD with the newly unlocked potential of AI4 is going to start soon – however, it may not necessarily come to customers right away.

FSD on Hardware 3

Currently, most of Tesla’s fleet is still on Hardware 3 – the Model 3 only changed over after the refresh, and the Model Y only changed over in late 2023. Even if AI4 brings drastic improvements, Tesla will still have to focus a lot of energy on optimizing their model so that Hardware 3 vehicles – some of which are less than a year old today, can still run the latest FSD updates.

Musk recently commented on X that Tesla is still optimizing FSD to run on hardware 3. He originally estimated that it would take about 10 days to optimize the code for HW 3, however, that date has come and gone. We’re now on day 15, and HW 3 owners are getting increasingly frustrated about the delay and the worry that HW 3 is reaching its limits.

FSD v12.5.1.3 is currently the latest FSD version available to the public. However, Musk said that this version doesn’t have HW 3 support yet, and it’ll be a new unreleased version that will roll out for HW 3.

Team is working on it.

This will be a different release number.

Tesla Introduces Hands-Free Frunk Opening in Update 2024.32.3

Not a Tesla App

In Tesla’s upcoming update, 2024.32.3, Tesla has added hands-free support for opening the vehicle’s frunk. This follows the Spring Update (2024.14), which added Hands-Free Trunk support for certain vehicles.

When hands-free trunk support was added earlier this year, it was supported on vehicles that include an ultra wideband chip, which includes the refresh Model S, new Model X, and the 2024 Model 3. Due to the hardware requirement, these will be the same vehicles that support the new Hands-Free Frunk feature. Legacy vehicles without UWB will unfortunately not support either feature due to the hardware requirement. UWB enables far more accurate tracking of the phone key, allowing Tesla to pinpoint its exact location relative to the vehicle.

The Cybertruck interestingly also includes an ultra wideband chip, however, it didn’t include the automatic opening of the gate earlier this year. However, we expect the Cybertruck to also receive the hands-free frunk opening in this 2024.32.3 update or relatively soon afterward.

Update: The Cybertruck is receiving hands-free frunk support in the 2024.32 update as well.

Hands-Free Frunk

The Hands-Free Frunk works similarly to the trunk feature – with an iPhone 11+ and a recent version of the app, you’ll be able to stand in front of your vehicle, and the Frunk will unlatch after sounding a chime. On some vehicles, the frunk will immediately open after being unlatched, however, you’ll need to manually close it.

This new feature isn’t enabled by default – you’ll need to go to Settings > Locks > Hands-Free Frunk to enable it.

At this time, Tesla doesn’t support UWB on Android devices, though both the Hands-Free Trunk and Hands-Free Frunk support will come to Android users in a future app update, according to Tesla.

Exclude Home

With the addition of the hands-free frunk opening, Tesla has also added a new option. You can now choose to disable the automatic opening when your vehicle is located at home to prevent you from accidentally opening. This will apply to the automatic frunk and trunk. In addition, in the Model X, you’ll also be able to disable the self-presenting doors at home. This is a great addition as many people have kept the hands-free feature disabled due to it awkwardly opening in the garage.

In the 2024.32.3 update, Tesla also mentions that they’ve improved the detection of the phone key, which should make the feature more reliable and faster when approaching the vehicle from the front or rear.

Tesla’s Referral Program Launches in Europe

Not a Tesla App

Following its recent launch in the United States and Canada, Tesla has launched their referral program in several European countries as well.

The program is available in Germany, Norway, France, the Netherlands, the United Kingdom and possibly others. The program is almost the same as the one available today in North America, with rewards for each referral and a discount for those referred. The cap in Europe is also ten per year.

This program comes right on the heels of a 0% financing offer for the Model Y in Sweden and France. While referrals aren't currently available in Sweden, the 0% financing still is.

European Referrals

The European Referral program accounts for country and local currency, where applicable.

The referral reward program is comparable to the one available in North America. After exchange rates, there is only an approximately 10% difference between the available rewards in the US and EU.

Other Countries

We expect this program to start rolling out to other European countries over the next few days or weeks, as Tesla continues to expand its referral program.
