Tesla has started rolling out FSD v14.3.2, delivered in firmware build 2026.2.9.8, to AI4-equipped vehicles. The release is the first Tesla self-driving update in several years that is more architectural than feature-driven: it merges the previously distinct AI models behind Full Self-Driving (Supervised), Actually Smart Summon and the Robotaxi fleet into one shared inference stack.
What is actually new
A single unified model
Before 14.3.2, a Tesla switched internal AI models when it transitioned between low-speed parking-lot operation (Smart Summon), supervised road driving (FSD), and the Robotaxi fleet's behaviour. v14.3.2 removes that switch. A single neural network now governs the car from the moment Summon pulls it out of a parking space through to its final autonomous maneuver at the destination. Tesla argues the practical consequence is that improvements to any one domain now benefit all three, and that the hand-off transitions feel notably more continuous to the driver.
Smart Summon and menu changes
Actually Smart Summon is the feature most directly improved by unification, with smoother lane-tracking in confined environments and faster decision-making when navigating around obstacles. The update also adds a redesigned FSD settings menu and introduces Blind Spot Warning While Parked — an alert that sounds inside the cabin if a vehicle or cyclist approaches the driver's door while the car is stationary.
Carry-over from v14.3
v14.3.2 inherits v14.3's rewritten AI compiler and runtime, rebuilt on MLIR, which Tesla says cuts reaction latency by approximately 20% relative to v14.2 and accelerates internal model iteration.
The HW3 question
On the Q1 2026 earnings call Elon Musk confirmed what many HW3 owners had feared: HW3 vehicles will not reach Unsupervised FSD. Tesla plans to keep HW3 cars on a parallel branch called FSD v14 Lite, targeted for release by June 2026, so that the installed HW3 base stays on a supported build. The AI4 computer has been the minimum platform for the unified model since v14.0; the new AI4+ board announced on the same call further widens the hardware gap.
What European owners get
EU-market Teslas receive firmware 2026.2.9.8 as part of the standard OTA pipeline, but the Supervised FSD stack it contains remains dormant pending regulatory approval. In practice, European AI4 owners gain the menu redesign, Blind Spot Warning While Parked, and the underlying platform changes — but Full Self-Driving and Actually Smart Summon remain unavailable as active driving features in every EU market. Tesla has not offered a concrete timeline for UN-R 157 or similar EU homologation progress on the unified model.
Rollout status
As of 24 April 2026, Tesla has widened 2026.2.9.8 from early-access testers to a broader AI4 pool. Owners in the United States and Canada are reporting receipt on both Model Y and Model 3 with AI4, with some Model S and Model X AI4 cars still waiting. Tesla has not published a country-by-country wave schedule.
