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.
Tesla Investor Relations has officially confirmed that they will conduct the Robotaxi unveiling event on October 10th in Los Angeles. Event sign-up will be done using a random drawing for Tesla shareholders. The final date for entries is a week from today, on September 17th at midnight, and the selected shareholders will be announced the week of September 23rd.
Sign Up
You’ll need to own Tesla stock ($TSLA) to participate and will be required to verify your shareholder status on the Investor Relations site. The random drawing provides a better opportunity for those who hold lots of Tesla shares, as they’ll have a higher number of entries. You get one entry per confirmed share held.
At the moment, there are no details on the timing of the event, nor anything about +1 attendees. However, one item of note is that event draw winners cannot transfer their tickets to another party – which means if you get a ticket, it's for you and nobody else.
If you’re located in the United States, you can use ‘Say’ – Tesla’s Investor Relations partner – to automatically verify your shareholder status. For those outside of the United States, unless you’re trading with an American bank, you will need to provide an updated statement showing shareholder status for September 2024. Say takes about 3-5 business days to verify statements, so be sure to sign up early.
Robotaxi Event
The Robotaxi event will take place at the Warner Bros. Discovery Studios in LA, and Tesla has been pre-emptively gathering FSD data around the neighborhood. This likely means that the event will include a demonstration of Robotaxi’s capabilities and a reveal of the Robotaxi itself. We’re hoping that attendees will have the opportunity to sit in and experience Robotaxi delivering them from Point A to Point B inside of the Discovery Studios set pieces.
It’s expected to be one of Tesla’s most interesting and notable events, as this is the first reveal of the much-talked-about Robotaxi, which has been Tesla’s goal for its Full Self-Driving software since Elon Musk’s Masterplan I.
Tesla’s latest FSD update, version 2024.27.5 brings some improvements when parking your vehicle. This is another undocumented, but one we’re happy to see.
Most recently, the Cybertruck received the undocumented change for the Hands-Free Frunk opening (video below). The Cybertruck also recently received Vision Park Assist, which included steering wheel guides in the visualization showing the direction the front and rear wheels were turned. However, it turns out this isn’t just for the Cybertruck.
Update: We’ve updated this article to mention that this feature isn’t included in update 2024.32 yet.

Due to the Cybertruck’s unique rear-wheel steering and steer-by-wire design, Park Assist in the Cybertruck displayed the path of the front wheels, and how they would swing while reversing.
This enhancement is also coming to every Tesla vehicle in FSD 12.5.2 and later. It’s also expected to be available in a future update for non-FSD vehicles. However, it’s unclear whether it will be a later revision of update 2024.32 or the next major Tesla update. This is a neat little update, as it helps drivers better understand and predict the path their vehicle will take during a turn.
Brandon, going by @teslaflexx on X, originally spotted the new visuals recently on an AMD-based Model Y running 2024.27.5 and FSD V12.5.2.
Any vehicles who are on update 2024.27.5 or 2024.27.20 should have access to this new feature.
Looks like Cybertruck wasn’t the only vehicle to get the new guide visuals with park assist. Much better than the lines! pic.twitter.com/tF9ZsWCcWy
