Tesla Starts Early Access for FSD (Monitored) Feature
Tesla's Full Self-Driving (FSD) Early Access Program, which has been under active development, is now open to owners of Hardware 4 (HW4) vehicles. This expansion marks a significant step in Tesla's quest to gather real-world feedback on its ongoing FSD development.
The FSD system, currently operating at SAE Level 2 automation, requires continuous driver supervision. While it is not yet a fully autonomous (Level 5) system, Tesla is making strides towards that goal.
Key Features and Improvements
Tesla's FSD Early Access Program requires the advanced onboard computer of HW4, designed to handle sophisticated neural network computations for FSD. A major FSD update, expected as of August/September 2025, aims to deliver a "step change" improvement in capability derived from the Robotaxi FSD builds. This update aims to reduce the driver attention "nag" and increase safety by allowing users more flexibility to look away from the road while maintaining supervision.
The update also includes a dramatic increase in the parameter capacity of neural networks running on HW4, from previous estimates of 4-4.5x parameter scale to up to 10x. This will improve handling of edge cases and produce more human-like driving behavior.
Practical Usage and Future Developments
HW4 vehicles are already in use for Tesla’s Robotaxi service in Austin, demonstrating practical usage beyond just development. While a next-generation AI5 computer (HW5) is expected in late 2026, HW4 remains a robust and effective platform for FSD supervised functionality today.
By the end of the year, FSD (Unsupervised) is expected to be available in more US cities. FSD (Unsupervised) is also slated for release in June for Tesla's Robotaxi network in Austin.
Enrollment and Data Collection
To enroll in the FSD Early Access Program, eligible HW4 vehicle owners can find a banner in the Tesla app indicating the option to "Enroll in FSD (Supervised) Early Access Program." Once enrolled, a message confirms the request submission. Participants are encouraged to share feedback about the new FSD builds.
During the FSD Early Access Program, Tesla will collect detailed vehicle data, including GPS, camera footage, and VIN-linked information. This data will help Tesla refine and improve its FSD technology.
Driver Responsibilities
Despite the advancements, drivers must remain alert and ready to take over at any time during the FSD Early Access Program. The banner appears for some owners, giving eligible users access to new FSD builds before they are rolled out more broadly.
In conclusion, Tesla’s FSD Supervised Early Access for HW4 vehicles is advancing rapidly, delivering substantial capabilities today but still requiring active driver supervision. The expansion of the FSD Early Access Program is a significant step towards Tesla's goal of fully autonomous systems in the future.
The FSD Early Access Program's expansion to HW4 vehicles will collect data, including GPS, camera footage, and VIN-linked information, to refine and improve FSD technology in both the automotive and transportation industries. Tesla, a pioneer in technology and finance, will use the gathered data to make strides towards autonomous vehicles, focusing on transportation and the automotive sector.
The forthcoming FSD update, scheduled for August or September 2025, will enhance the FSD system by reducing driver attention "nags," increasing safety, and improving handling of edge cases, ultimately striving for more human-like driving behavior. This update is expected to have significant implications for the finance industry, as it may increase the appeal and accessibility of Tesla's autonomous vehicles, potentially disrupting traditional transportation models.
