Tesla has recently launched the FSD V14.3.3 (Supervised) software update, a notable release that comes with substantial spring-themed enhancements and bears the software version number 2026.14.6.6. This update focuses on refining the fundamental performance of the autonomous driving system, particularly enhancing the driving speed of vehicles in low-speed parking lot environments. The Smart Summon feature has undergone significant improvements, with its maximum speed being elevated from 6 miles per hour (approximately 9.7 km/h) to 8 miles per hour (approximately 13 km/h), thereby enhancing its practicality for everyday use.

Moreover, Tesla has upgraded the neural network reinforcement learning module and visual encoder, and rewritten the AI compiler program. These enhancements collectively contribute to a faster system response time, improved model iteration efficiency, and a smoother ride experience. Additionally, the system's capability to recognize and respond to irregular obstacles has been fortified, ensuring a safer and more reliable autonomous driving experience.

This latest version is being progressively rolled out across the United States and Canada, with Tesla CEO Elon Musk praising the update as delivering an outstanding user experience.
