Thanks, that's helpful. Is the collaboration with Google ongoing then? Can you give me a sense of what magnitude of computing resources training on the full dataset involves? Is it simply the days-to-weeks per model described in the documentation? Would it be reasonable to continually retrain existing models with additional community-contributed data, rather than starting from scratch each time?
