Isn't that what "Attention is all you need" was about anyway? Does not sound like news to me.
I’m still hesitant to interpret this as “thinking ahead” without at least seeing some more back-and-forth in the literature first, though. This just seems like one of those spots where it makes sense to give other researchers some time to come up with additional hypotheses to explain the observations instead of focusing on the first one anyone proposes in isolation.
The model would construct/hallucinate pre-conditions to satisfy some final output value that the model was predisposed to.
