Tesla's Full Self-Driving (FSD) system is receiving significant "under the hood" upgrades to its visualization capabilities, as highlighted by a recent social media post from "Whole Mars Catalog." The tweet, stating "Big upgrades under the hood to the FSD visualization," points to ongoing advancements aimed at enhancing the system's understanding of its environment and improving the user experience. These developments are part of Tesla's broader FSD roadmap, which includes substantial architectural changes.
A core component of these upgrades is a new FSD model featuring a 10x increase in parameters, representing a significant architectural leap. This enhanced model, coupled with improvements in video processing to reduce data loss from compression, allows FSD's neural network to process more nuanced information. The goal is for the system to understand the world with greater detail and react in more human-like ways, particularly in handling complex edge cases.
Recent software updates have already begun rolling out smoother FSD visualizations to users. For instance, FSD 12.5.4.2 on Hardware 3 vehicles has shown "significantly smoother" rendering, addressing previous issues like slow frame rate refresh. Furthermore, Tesla has resolved a long-standing bug in its FSD visualization system that caused surrounding vehicles to "jitter" or leap across lanes, a fix that notably improves user confidence in the system's real-time perception.
Beyond general smoothness, specific visualization elements are also being refined. Future updates will enable the rendering of objects like trailers and Cybertrucks within the FSD display. Visualizations for safety features such as Lane Departure Avoidance (LDA) and Lane Assist have also been updated, now featuring a distinct blue line to indicate lane boundaries. Tesla anticipates a customer build incorporating these advancements to be released in Q3 2025, with a much larger "4.5X parameter" model, tentatively FSD V14, slated for wider release later in 2025.
