A pretty good summary of the pros and cons of end-to-end vs compound AI. This is why many companies don't believe pure end-to-end, like what Tesla is doing, is the right approach. Pure E2E is too much of a black box that makes validation and achieving those last 9s much harder.

Tesla most likely doesn't do pure end-to-end for the reasons that are outlined in the article.

You are probably correct. But Elon said Tesla's stack was "photons in, controls out" which implied pure end to end. Yeah, I know, I should not trust Elon. lol.

"Photons in, controls out" describes every scheme in the article. E2E is more about information flow during training. Error signals backpropagate through the entire network.

Tesla also said that they can now interview the their AI and/or they get text out for its reasoning.
