Tesla owners have been eagerly awaiting the next major FSD release, and it looks like that wait may be almost over. Last night, Elon Musk officially confirmed that FSD v14.3 is being tested internally.
He went on to say that he expects it to go into wide release in a “few weeks.”
The Long Road from December
If the FSD v14.3 nomenclature sounds familiar, it’s because this specific build has been on the radar for quite some time. Originally, Elon had mapped out a software roadmap that slated v14.3 for a December 2025 launch.
However, as is often the case with the complexities of solving real-world AI, Tesla pivoted. Instead of dropping a large change with v14.3 at the end of last year, the Tesla fleet received a long series of v14.2.x bug fix builds.
These iterative updates brought minor refinements to the vehicle's driving behavior, prioritizing stability over sweeping architectural changes. Now, it seems the Tesla AI team is finally ready to push the true v14.3 overhaul to the public.
What Will FSD 14.3 Bring?
Musk hasn’t yet mentioned what would be included in the release. At the top of the wishlist is Banish. This is the next evolution of Autopark, which would allow your vehicle to drop you off at the door of your destination and autonomously navigate a crowded parking lot to find a spot and park itself.
The second item on the wishlist is improvements to Actually Smart Summon and Basic Summon, which are both built on the older FSD v12 stack and Autopilot stacks, respectively. Since these features operate on much older logic, they’re not as effective, smooth, or intelligent as FSD is in general.
Transitioning them to the latest end-to-end neural network architecture would be a massive upgrade for two of the most defining autonomy features and dramatically improve their reliability, speed, and safety.
Back in December, Musk famously said that FSD 14.3 would be the release that would make your car feel “sentient.” Back when Tesla released FSD 14.1, Musk stated that many more improvements were still to come in FSD v14, possibly hinting at new functionality. V14.3 could very well be the version that adds capabilities like Banish, rather than just refining existing features.
At this point in FSD’s cycle, most of the features needed to drive a car autonomously have been implemented. Tesla slowly pieced it together with highway driving, city streets, shifting between drive and reverse, and more recently, auto parking at the destination.
Tesla now needs to improve them to the point where the vehicle can operate safely with no one in it, which would then open the door to including banish.
Improved Reasoning Capabilities
Beyond parking lot tricks, v14.3 is expected to introduce a major change in how the vehicle actually thinks while navigating city streets.
Tesla's Vice President of AI Software, Ashok Elluswamy, recently confirmed that reasoning was already implemented for FSD v14.2. However, v14.3 is supposed to bring another leap in the neural net's ability to handle complex, unseen edge cases by actively reasoning through the scenario rather than just reacting to immediate obstacles.
As Tesla aggressively pushes toward its stated 10-billion-mile goal for unsupervised FSD, v14.3 will likely feature these improved reasoning capabilities more prominently. By allowing the car to make more human-like, contextual decisions, this update could be a bridge between the current supervised system and the autonomous Robotaxi future.
