In a post on X, Elon Musk confirmed that vehicles with Hardware 3 will be receiving FSD V12.5 in about 10 days.
When FSD V12.5 was rolled out initially, it only rolled out to Model Y vehicles with AI4 (Hardware 4). However, just a few days later, FSD V12.5 started rolling out to most AI4-based vehicles.
Hardware 3
Hardware 3 owners have been left feeling behind on this, especially since the divergence between Hardware 3 and AI4 wasn’t supposed to start happening until later this year. Elon has mentioned that even though AI4 is still emulating Hardware 3, the additional compute capacity available on the newer hardware makes it easier to develop.
This pretty much means that Tesla is developing for Hardware 3 but is using the unconstrained compute power of AI4 to test and do initial rollouts. After optimization, it then rolls out to Hardware 3 vehicles. This is similar to how most software is often made – on far better PCs, and then scaled down and optimized to better fit the average computer.
But Tesla clearly isn’t abandoning their Hardware 3 and Tegra-based infotainment (MCU 1) customers just yet. Update 2024.26.3 brings FSD V12 to MCU1 vehicles for the first time. These vehicles are based on an older infotainment chipset from NVIDIA. That’s a great leap in optimization and compatibility and demonstrates Tesla and Elon’s commitment to bringing Unsupervised FSD to any vehicle produced after 2016.
V12.5 is Significant
FSD V12.5.1 has also shown some amazing improvements, with the capability to navigate parking lots and unpaved/unmarked roads being demonstrated by AIDRIVR on X below. That’s one of the key components that Tesla will need for its Robotaxi, as well as for Actually Smart Summon, Park Seek, and Banish Autopark. And Elon has said that there is more to come.

We haven’t heard about these features making it to FSD V12.5 just yet, but we do know that sunglasses-capable hands-free, end-to-end highway stack, more natural lane changes, and Cybertruck FSD are supposed to be coming soon. This laundry list of improvements is found in the Update 2024.20.15 Release Notes, all listed as Upcoming Improvements.
We’re excited to see FSD V12.5 coming to Hardware 3 vehicles – especially as the vast majority of Tesla’s current fleet is still on Hardware 3, not AI4. While Elon has said Tesla doesn’t envision an upgrade path between Hardware 3 and AI4 due to the complexity, there’s always a chance Tesla will develop new AI4-based hardware that meets the power consumption capabilities and space constraints of vehicles running HW3.
