Tesla is developing a new Full Self-Driving (FSD) model featuring approximately 10 times more parameters than the current version and significant improvements in video compression loss. CEO Elon Musk indicated that if testing proceeds successfully, the upgraded FSD system could be publicly released by the end of September 2025. The enhanced model aims to improve Tesla's autonomous driving capabilities, potentially enabling the system to handle more complex driving conditions. This development aligns with Tesla's ongoing commitment to advancing its AI-powered self-driving technology amid challenges such as declining car sales.
