Tesla (TSLA) has begun the rollout of a new Full Self-Driving (Supervised) AI software update, FSD v14.3.4 (firmware version 2026.14.6.10).
This new FSD update is a minor point release to the previous FSD v14.3.3 (2026.14.6.6). Although it’s not a major update, Tesla and SpaceX CEO Elon Musk announced its rollout on X himself.
Interestingly, it was one of Musk’s busiest and most important days of his life, the day SpaceX (SPCX) started trading on the NASDAQ. Musk still found the time to make this minor FSD rollout announcement.
The release notes of FSD v14.3.4 also don’t mention any major new changes or improvements to the system. The Upcoming Improvements section of the release notes removed a point that previously said: “Improve driver monitoring system sensitivity with better eye gaze tracking, eye wear handling, and higher accuracy in variable lighting conditions.”
The rest of the upcoming improvements remain the same as the previous version.
FSD v14.3.4 (2026.14.6.10) Rollout Status
Tesla software update 2026.14.6.10 (FSD v14.3.4) is currently rolling out to a limited number of users. According to the tracking stats by TeslaFi.com, as of this writing, only 0.1% of the Tesla fleet has installed the FSD v14.3.4 update.
This new update is rolling out to all the Hardware 4 (HW4/AI4) Tesla vehicles in North America, including the Cybertruck. This is because this specific version of FSD 14 is built for this region. In Europe, Tesla has just rolled out the FSD v14.2.2.6 update.
Both the North American and European versions of Tesla’s Full Self-Driving (Supervised) software are different. This is basically because of different traffic signs, lights, rules, and road conditions, to name a few variables.
Tesla Cybertruck is getting the Actually Smart Summon feature for the first time in the 2026.14.6.10 update.
FSD v14.3.4 (2026.14.6.10) Official Release Notes
Full Self-Driving (Supervised) v14.3.4 includes:
- Upgraded the Reinforcement Learning (RL) stage of training the FSD neural network, resulting in improvements in a wide variety of driving scenarios.
- Upgraded the neural network vision encoder, improving understanding in rare and low-visibility scenarios, strengthening 3D geometry understanding, and expanding traffic sign understanding.
- Rewrote the AI compiler and runtime from the ground up with MLIR2, resulting in 20% faster reaction time and improving model iteration speed.
- Mitigated unnecessary lane biasing and minor tailgating behaviors.
- Increased decisiveness of parking spot selection and maneuvering.
- Improved parking location pin prediction, now shown on a map with a (P) icon.
- Enhanced response to emergency vehicles, school buses, right-of-way violators, and other rare vehicles.
- Improved handling of small animals by focusing RL1 training on harder examples and adding rewards for better proactive safety.
- Improved traffic light handling at complex intersections with compound lights, curved roads, and yellow light stopping – driven by training on hard RL examples sourced from the Tesla fleet.
- Improved handling for rare and unusual objects extending, hanging, or leaning into the vehicle path by sourcing infrequent events from the fleet.
- Improved handling of temporary system degradations by maintaining control and automatically recovering without driver intervention, reducing unnecessary disengagements.
- Unified the model between Actually Smart Summon, FSD, and Robotaxi for more capable and reliable behavior.
- Actually Smart Summon max speed is now increased to 8mph (13km/h).
- Help Tesla improve Self-Driving by selecting an intervention reason on the main screen after taking over.
- You can now see distance traveled in FSD (Supervised) without an intervention. The Self-Driving App will also show your longest intervention-free streak.
Upcoming Improvements
- Expand reasoning to all behaviors beyond destination handling.
- Add pothole avoidance.
