Doesn't Tesla have their own "Dojo" custom AI chips? There seems to be a bit of pointless duplication either way between Tesla and X/xAI's developments in this space.

Judge by yourself where it's now.

Folks, it's all smokes and mirrors !

On the latest TSLA event, Elon said Dojo was 5% of their training compute (the rest being nvidia). Although he hoped future dojo versions would improve.
