If you used Baidu's services, you might be more impressed. In any case, one barrier to rolling these things out to production is that it takes time to get them into production, and there are cost challenges: you represent too little ad revenue to justify a whole GPU devoted to you. Baidu has been experimenting with aggressive model reduction and batching up tasks and efficient GPU server design, but it's still a challenge to roll out the best deep learning results on fractions of a penny budgets.

But rolling out a paid service like that comes with a lot of expectations that being part of a free app doesn't.
