Nice! I wonder how well phones will handle these models. Android pushes apps to be under 512MB. But maybe they can offer a single, larger model that is pre-loaded at all times for all apps. Similar to how they do translate models these days. 

But yeah, I think testing on the desktop will be the way to go for now. Things will change so much on phone libs that I am not sure if it's worth trying to something like that now on phones.
