There is nothing for the buyer to see. They are buying a service or capability and what silicon that runs on is here or there to them.

A simple example is the Google New Speech synthesis service. It is done using NN on their TPUs but nobody needs to know any of that.

What the buyer knows is the cost and the quality of the service.

Now Google had to do their own silicon to offer this as otherwise the cost would have been astronomical. The compute to do 16k samples a second with a NN are astronomical.

If I could not see it myself I would say what Google did was not possible.

Just hope they share the details in a paper. If we can get to 16k cycles through a NN at a reasonable cost that opens up a lot of interesting applications.
