FSD Beta v12 upgrades the city-streets driving stack to a single end-to-end neural network trained on millions of video clips, replacing over 300k lines of explicit C++ code.Tesla's next milestone for FSD Beta will be v12, which will include a fundamental shift in how the vehicle is controlled.Neural Networks
The highlight of FSD Beta v12 lies in its increased usage of neural networks. A neural network in artificial intelligence is akin to the human brain's network of neurons. It is a complex system that learns from large datasets - in Tesla's case, millions of video clips - to recognize patterns and make informed decisions. This machine-learning approach allows the system to adapt and improve continuously.

Neural networks are already used for determining surroundings, detecting objects, and more, but FSD v12 will be the first time Tesla adds neural networks that control the vehicle's acceleration, braking, and steering. According to Musk, FSD Beta v12 features end-to-end neural networks, meaning that these AI networks are used for everything, from vehicle input (cameras) to vehicle output (steering).Automatic Set Speed Offset allows Autopilot to drive at the speed that it determines is most natural. This considers factors like road type, traffic flow, environmental conditions, speed limit, and the selected Full Self-Driving (Beta) Profile setting (Chill, Average, or Assertive).

This new setting is off by default, but can be turned on under Controls- Autopilot -Automatic Set Speed Offset.

This gives the vehicle more freedom when determining its speed, such as when passing or keeping up with other vehicles.With FSD Beta v12, the vehicle is now able to complete U-turns when they're part of the route.
