FSD Version History › FSD 11.4
Tesla FSD 11.4
Overview
FSD 11.4 is a major single-stack release merging the highway and city driving stacks into one unified neural network pipeline. This unified model handles all driving scenarios without mode-switching.
What's new in FSD 11.4
- Unified highway and city driving stack — one neural network for all roads
- Elimination of the mode-switching boundary between highway and city logic
- Improved consistency as vehicles transition between road types
- Better overall calibration of speed and position on unfamiliar roads
- Foundation for the V12 end-to-end neural architecture
Known issues
- Early reports of some highway-to-city transition edge cases
- Some reduction in performance in certain previously well-handled scenarios during the merge
Community feedback
FSD 11.x single-stack is viewed as the precursor to V12. Merging the stacks eliminates a class of bugs tied to mode transitions and sets the stage for the full end-to-end V12 redesign.
