What changed
Three useful takeaways
Three useful takeaways from comma’s original release announcement.
Lower parked power on comma four
The announcement reported a 77% reduction in the device’s parked idle power draw, from 225 mW to 52 mW.
A cleaner comma four interface
Setup, Wi-Fi, navigation, scrolling, and several smaller interface details received updates.
The simple explanation
What is a world model?
It is software that learns to predict what may happen next in a driving scene. Comma used that learned environment to practice and train the driving policy, the part that chooses a path and speed.
The important distinction is training, not a new mode that drives without your attention. The driver remains responsible for the vehicle at all times.
