Tesla Motors CEO Elon Musk teased on Wednesday that new improvements for the company's Full Self-Driving model are on the way.

Shares of Tesla ( TSLA ) rose 3% in Wednesday trading.

"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," wrote Musk on social media site X.

The latest widely deployed version is FSD v13.2.9 for vehicles equipped with Tesla's newest AI4 ( also known as HW4 ) computer. Older HW3 vehicles continue to receive only modest bug fixes and remain on v12.6.3

Looking ahead, a big milestone for Tesla will be the launch of "FSD Unsupervised," which is the company's vision for truly driverless operation. Tesla ( TSLA ) aims to begin releasing FSD Unsupervised in select U.S. cities by the end of 2025.
