Update in question is “Upgraded modeling of lane geometry from dense rasters (‘bag of points’) to an autoregressive decoder that directly predicts and connects ‘vector space’ lanes point by point using a transformer neural network.”

So, $tsla #FSDBeta creates a 3D model of…

…reality.

As I interpret the notes, previous versions, the 3D geometry is based directly on the camera inputs, which generates excessive qty’s of 3D points.

This is now fed into a new neural net that can distill them into a more sparse-yet-adequate 3D model.

Importantly…
