I wonder how this intersects with their interest in "unbiased" models. Scare quotes because their concept of unbiased is scary.

Elon gives an unvarnished look at what they mean by 'unbiased' with respect to models. It's rewriting the training material or adding tool use (searching for Musk's tweets about topics before deciding it's output) to twist the output into ideological alignment.

"unbiased", in the world of realpolitik, means "biased in a manner to further my agenda and not yours".
