Tesla Announces Major Full Self-Driving Upgrade with 10X More Parameters

Tesla is taking a giant leap forward in autonomous driving technology with the announcement of a new Full Self-Driving (FSD) model that features approximately 10 times more parameters than its current version, along with significant improvements in video compression efficiency.

The development was confirmed by CEO Elon Musk via a post on his verified X (formerly Twitter) account on August 6, 2025.

“Tesla is training a new FSD model with ~10X params and a big improvement to video compression loss. Probably ready for public release end of next month if testing goes well,” Musk wrote.

The latest upgrade represents one of the largest architecture overhauls of Tesla’s FSD software to date. With significantly more parameters, the new model is expected to better handle complex real-world driving scenarios, including unstructured environments, unpredictable traffic behaviors, and nuanced urban navigation.

Experts suggest that increasing the model’s parameter count enables it to recognize and respond to a broader range of inputs and driving contexts with greater accuracy and reliability. Coupled with enhanced video compression, this development also implies more efficient data handling from Tesla’s onboard cameras, potentially reducing latency and improving system response times.

Pending final validation and safety testing, Tesla plans to release the new FSD model to the public by the end of September 2025. The company is currently conducting rigorous trials to ensure the software meets safety and performance standards before deployment.

This update aligns with Tesla’s long-standing goal to achieve full autonomy and roll out a robotaxi network, a vision Musk has championed for years. The move also comes amid growing competition in the self-driving space, with rivals like Waymo, Cruise, and Apple ramping up their own autonomous vehicle efforts.

Tesla’s Full Self-Driving system is currently in beta testing across multiple U.S. states, with hundreds of thousands of vehicles collecting driving data to train the AI model.

If successfully rolled out, this next-gen FSD software could mark a turning point for Tesla’s autonomous ambitions, bringing the company closer than ever to achieving Level 4 or 5 autonomy—where a car can operate without human intervention under most or all conditions.
