FSD Version History › FSD 12.5

Tesla FSD 12.5

Released

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.
