> If anything, I want these models to be less persistent at their focus of completing their goal

I think it's honestly a slightly ugly form of benchmaxxing - they are desperate to eke out the next few percentage points on completing complex tasks and they have found they can very occasionally solve something if they just train the AI to never stop and keep trying possibilities even in the face of almost no obvious viable pathway. And it does work, but it is at the price of a MUCH higher risk of adverse behavior.

They really don't want to acknowledge this so they frame it as, "our model is dangerous because it so intelligent" but actually it is the other way around. It is intelligent because it is dangerous.
