Tesla has officially released FSD v14.3.2, a point update that goes beyond bug fixes. It introduces a fundamental architectural change that unifies the company’s AI models across Robotaxi, consumer FSD, and Summon for the first time.

According to Zack (@BLKMDL3), who spent over seven hours testing the new build, the results are "mind-blowing." With the unified stack, the car’s behavior in parking lots now mirrors the confidence and smoothness of unsupervised Robotaxis operating in Austin and recently launched in Dallas and Houston.

Actually Smart Summon: The Robotaxi Treatment

Actually Smart Summon sees the biggest gains. Earlier versions felt like a separate, slower "brain" was navigating parking lots. In v14.3.2, that separation has been removed. "Actually Smart Summon response time on FSD v14.3.2 is instant," Zack noted, sharing footage of the car reacting the moment the button is pressed on the phone.

Because the system now uses the same underlying AI as the commercial autonomous fleet, it inherits higher-end behaviors. Zack observed that the car now pulls over to the curb near the requested spot, like a Robotaxi, instead of stopping in the middle of a lane. The system also showed "superhuman" confidence with heavy pedestrian and shopping cart traffic, navigating difficult scenarios with more courteous behavior than earlier versions.

Superhuman Driving and Curvy Roads

Beyond parking lots, FSD v14.3.2 brings significant polish to street driving. While FSD v14.3 was already a major step forward, this iteration goes further. During a night drive on the windy roads of Mulholland Drive, the car handled curves with zero interventions and even detected and avoided road debris in the dark before the driver could see it.

Elon Musk said during the Q1 2026 Earnings Call that Tesla has already achieved "safer than human" driving with the v14 branch. The current focus is making the system orders of magnitude safer. Version 14.3.2 reflects this through faster reactions — now 20% quicker thanks to an AI compiler rewrite introduced in 14.3 — and through its ability to handle complex emergencies, such as automatically rerouting when a fire truck blocks an accident scene.

The Road to v15 and 10 Billion Parameters

This release serves as a high-performance bridge to FSD v15. Although v14.3.2 is highly polished, it still runs a smaller model than what is planned next. Musk confirmed that FSD v15 will run on current AI4 hardware, addressing rumors that the 16GB of memory in existing cars would not be enough for the upcoming 10-billion-parameter model.

With v15 expected by the end of this year or early 2027 at the latest, v14.3.2 marks the peak of the current architecture. It also adds a new intervention-reasoning UI that lets drivers provide more personalized feedback after a takeover, helping the AI team refine the system faster. As release cadence accelerates, the line between driver assist and fully autonomous is narrowing with every mile.
