Tesla FSD v15: Musk Teases “Unsupervised” Safety With 10x Larger AI Model

Tesla CEO Elon Musk has set a high bar for the next major leap in Full Self-Driving technology, claiming the upcoming version 15 will reach a level of safety that far exceeds human capabilities.

Responding to reviews of the current FSD v14.3 (which was supposed to be the last big puzzle piece), Musk noted that while minor point releases will continue to polish the current experience, the real breakthrough lies with v15. According to Musk, this version is designed to handle completely unsupervised and complex situations, which remains the ultimate goal for the automaker’s autonomous driving software.

The buzz around v15 centres on what Musk calls the large model. In the world of AI, parameters are essentially the connections or neurons in a digital brain. A model with more parameters can process more information and understand increasingly complex patterns. Musk confirmed that v15 will utilize a 10x parameter model, providing the car’s AI with a much higher capacity to learn from the trillions of miles of video data Tesla has collected.

This massive increase in brain power is expected to help the vehicle better predict unpredictable real-world scenarios, such as a cyclist swerving or a pedestrian hesitating at a busy intersection. Musk admitted that advancement with the current small model has been so quick that the larger architecture hasn’t quite caught up yet, but once it does, v15 will become the new flagship for the fleet.

For now, Tesla owners can expect polish updates in the v14.3 series to smooth out lane changes and fix minor bugs. However, the shift to v15 represents a massive architectural change that Musk frames as the version that finally makes true, unsupervised driving a reality.

Now, the bigger question is whether HW4 owners will be able to support FSD V15, or if it will require newer HW5 hardware. Many HW4 Tesla owners fear they might get left behind like HW3 vehicles, which have been waiting patiently still for FSD 14 lite, expected this summer.
