I think the interesting question is whether the average consumer cares? a 4B model should hit roughly the same numbers as GPT5.5 sometime in December/March. That is more than capable of performing a variety of complex work tasks.
You just can’t compress 1.5T into 4B without losing useful stuff.
But that doesn’t matter that much. If 4B can compose tools, retrieve info, and not get stuck in loops that is going to handle a lot of use cases
