Tesla is now training a new Full Self-Driving model boasting “big” video improvements and size upgrades, CEO Elon Musk said Wednesday on social media.

“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,” the tech billionaire said in an update on the X social media platform.

FSD is a partially automated driving system that seeks to enable Tesla vehicles to navigate and maneuver in driving situations with minimal driver assistance. Owners must keep their hands on the wheel, and remain ready to take over steering or braking at any time. It also serves as an upgrade to the company’s Autopilot driver assistant, which is already available in Europe and China.

The system is based on an artificial intelligence model that helps the car’s cameras and sensors perceive the world around it. Musk’s comment on “10X params” refers to a larger parameter size. In the case of AI models, that usually means it is a bigger model that is trained on more data and is more capable.

FSD has been a central pillar of Musk’s strategy for Tesla’s revenue growth and tech advancement in the increasingly competitive electric vehicle market, where Chinese automakers have stepped up to the plate.

Tesla bulls expect the company’s future will be in autonomy as Musk’s automaker focuses on ramping up its offering of self-driving features.

Tesla launched its robotaxi service in Austin, Texas, this year.

But right now, the market is focused on how Tesla’s core business of selling cars is doing. And it has been challenging. Tesla most recently reported a 16% decline in automotive revenue in the second quarter and has also been notching steep declines in its European sales.

The company’s stock has taken a bruising this year that has been exacerbated by reputational damage from Musk’s now-severed relationship with the White House administration. Tesla shares were down 23.55% this year as of Wednesday morning.
