I don't think so, they have different constraints and require different optimizations, being able to produce one of them doesn't mean you'll automagically be good at the other.

but that's denying the singularity boostrap theory. Which I don't agree with, but if you can't harness a large model to make a small model, then we're going to have problems brining about the singularity.

If you do think there's some magical singularity, how do you comport?
