FSD 14.3
Firmware
2026.2.9.6
Release Date
- - 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 Al 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.
- Expand reasoning to all behaviors beyond destination handling.
- Add pothole avoidance.
- Improve driver monitoring system sensitivity with better eye gaze tracking, eye wear handling, and higher accuracy in variable lighting conditions.
