Release Notes for 2026.38.5.5 - FSD 14.3.12

Full Self-Driving (Supervised) v14.3.12 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 MLIR, 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 RL 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. - Improved driver monitoring system sensitivity with better eye gaze tracking, eye wear handling, and higher accuracy in variable lighting conditions. - 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. - Parking options now display on the map when arriving at your destination. Upcoming Improvements: - Expand reasoning to all behaviors beyond destination handling. - Add pothole avoidance.

- You can now select an arrival option such as Carpark, Indoor Carpark, Street, Driveway, and Pull Over for Robotaxi-style drop offs. - Your preferences for arrival options and preferred parking positions are persisted for each destination. - Our reasoning model will assess the suitable options for your destination and pick an intuitive default. - The navigation pin will be adjusted based on the selected Arrival Option.

FSD (Supervised) will now determine the appropriate speed based on a mix of driver profile, speed limit, and surrounding traffic. - Driver profile now has a stronger impact on behavior. The more assertive the profile, the higher the max speed. - Right scroll-wheel up/down now adjusts Speed Profile setting rather than your precise max speed offset selection in mph or km/h. - Introduced new Speed Profile SLOTH, which comes with lower speeds & more conservative lane selection than CHILL. - Introduced new speed profile MAD MAX, which comes with higher speeds than HURRY.

- You can now view your Self-Driving stats under Controls > Self-Driving. - Start Self-Driving with a tap of the touchscreen from Park, or any time during your drive. - Adjust settings like the Speed Profile and Arrival Options directly from the Self-Driving visualization on the center display.

Brake Confirm for the Start Self-Driving button is now defaulted off. When disabled, Start Self-Driving will not require you to press and release the brake to confirm engagement. You can enable Brake Confirm in Self-Driving > Brake Confirm.

Spread holiday fear year round with Halloween Mode. Put a Ghost Costume on your car visualization. Turn on Trick or Treat Mode to play spooky sounds and flicker the lights when visitors approach. Schedule a haunting light show, and turn your car into a chilling Photobooth!

Set your desired Arrival Energy for any trip from your phone. Open the location tab in the Tesla Mobile App, enter your destination, and tap Set Arrival Energy. Requires Mobile App v4.58.0 or later.
