Tesla Rolls Out FSD v14.3.3: Smart Summon Speed Boosted to 13 km/h

Tesla has rolled out the FSD v14.3.3 (Supervised) software update to vehicles in the U.S. and Canada, corresponding to software version 2026.14.6.6. This update includes multiple optimizations to the Autopilot system, most notably increasing the maximum speed of the Smart Summon feature (ASS) from 6 mph (approximately 9.7 km/h) to 8 mph (approximately 13 km/h). The FSD core software now incorporates an upgraded reinforcement learning module that refines driving decision logic and features an enhanced vision encoder to improve the vehicle’s perception of three-dimensional space, thereby boosting recognition accuracy for complex road conditions and traffic signs. Additionally, Tesla has rewritten its AI compiler, resulting in a 20% improvement in system response speed and greater efficiency in model iteration. This update also enhances ride comfort by reducing unnecessary lane deviations and close-following behaviors, while improving the system’s ability to detect and respond to rare or atypical obstacles.
