Which ai video tools do native audio and which are just bolting on a soundtrack after?

Half these tools claim output with audio and it turns out they mean they picked a stock track for you. i want the model generating sound that matches what's on screen. From what i can tell only a couple of models do it natively. which ones, and does it survive being cut into a real edit or does it fall apart the moment you trim?

I know seedance doing it, what else?
