Tesla software update 2026.21.5, released on August 1, 2026, covers supervised driving and vehicle convenience. Its 4 documented entries explain changes to the ownership experience, from the features used inside the cabin to the software operating behind them. Availability depends on the vehicle and the requirements of each entry.
FSD (Supervised) v14.3.7 is listed for Model S, Model 3, Model X, Model Y and Cybertruck with HW4. Availability follows the requirements of each entry; the update number alone does not identify which driving branch a vehicle receives.
FSD (Supervised) v14.3.7 improves learning and visual understanding for unusual or low-visibility situations. Changes address parking decisions, lane positioning and responses to emergency vehicles, school buses, animals and complex traffic lights. The revised AI runtime is described as delivering 20% faster reactions. These refinements concern how the driving system interprets the road and chooses maneuvers while the driver continues to supervise. Intervention feedback and driving-distance statistics also provide more information about the journey.
Actually Smart Summon and Dumb Summon are listed for Cybertruck. This extends the documented Summon feature set to that vehicle, complementing the supervised-driving changes elsewhere in the release. Owners should read the separate Summon instructions for the controls and operating conditions rather than treating the FSD version number alone as a complete description of Summon support.
Full Self-Driving (Supervised) describes assistance with leaving a parked position, following navigation routes, changing lanes, making turns and parking at the destination. Drivers can activate the feature through the screen or right scroll-wheel button when available. The driver continues to supervise the road and remains responsible for taking control whenever needed.
Camera Preview opens individual or grid camera views while driving. This entry is listed for newer Model S, Model 3, newer Model X, Model Y and Cybertruck with HW3 and HW4.
