Tesla has begun deploying Full Self-Driving Supervised v14 Lite to early-access owners of vehicles equipped with Hardware 3 computers. The update, version 2026.20.5.1, brings features previously limited to newer hardware. Initial rollout targets a small group before wider release in coming weeks.
Tesla started the deployment on June 29 to a narrow set of early-access drivers with AI3 hardware. The software distills capabilities from the HW4 v14 version, enabling reinforcement learning and other advances on the older system that has roughly 15 percent of the memory bandwidth of newer computers.
Release notes list improved responsiveness in navigation, merges, pedestrian interactions, traffic lights and cut-ins. Additional changes include parking, unparking and reversing functions, arrival options for driveways or curbside stops, and always-available speed profiles.
Tesla vice president of AI Ashok Elluswamy said the build will expand based on initial feedback. Elon Musk posted that the AI3 rollout marks completion of a difficult engineering task.
Owners of older models had waited 14 months since the prior major release. The company plans to analyze real-world data before broadening availability globally.
