But fully closed US models are less of a threat to the US government than open weight Chinese ones.
Of course we in Europe should completely trust fully closed US models, otherwise tariffs/sanctions will ensure.
Well maybe. But its also a security risk for the US government.
Any legal deterrent can be waved away by saying “but what if they do it secretly?”
It doesn't change the fact that US companies are subject to US laws. Conspiracy would just make the penalties steeper. Is it pointless to have laws against fraud, espionage, tax evasion, etc?
