Overview
- Tesla began sending FSD v14.3 to Early Access members on Tuesday, with early installs showing up in the U.S. and Canada.
- The release rewrites the AI compiler and runtime on MLIR, a tool that compiles neural networks more efficiently, which Tesla says cuts reaction time by about 20%.
- Upgrades to the vision encoder and reinforcement learning improve 3D scene understanding, low-visibility performance, and recognition of rare driving situations.
- Tesla says the build responds better to emergency vehicles and school buses, navigates unusual objects, and can recover from brief system hiccups to avoid unnecessary disengagements.
- The rollout targets HW4 vehicles and adds clearer parking spot prediction with a map “P” icon, while Canada access remains subscription-only at CAD $99 per month after Tesla ended one-time purchases in February.
