They have super sustainable revenue. They are deadly supply constrained on compute, and have a really difficult balancing act over the next year or two in which they have to trade off spending that limited compute on model training so that they can stay ahead, while leaving enough of it available for customers that they can keep growing number of customers.
IT's cute you think they're gonna do any full training of a model. As soon as they can extract cash from the machine, the better.
But do they? When was the last time they declined your subscription because they have no compute?
