FSD Version History › FSD 12.5
Tesla FSD 12.5
Overview
FSD 12.5 is a significant iterative improvement to the V12 neural planner, bringing improved city street navigation and reduced false positives in obstacle detection.
What's new in FSD 12.5
- Improved city street driving — better gap acceptance and yielding
- Reduced phantom braking on highways and expressways
- Better handling of roundabouts and traffic circles
- Improved behavior near school zones and crosswalks
- More consistent speed adjustment for posted limits
Known issues
- Some reports of hesitation at complex highway weaves
- Occasional overreaction to overhead signage on certain roads
Community feedback
FSD 12.5 is broadly regarded as the most capable V12 release. Community intervention rates drop noticeably. Many testers report double-digit improvements in miles between disengagements.
