The Ingenuity mission will start slow, beginning with a testing routine.

The solution was to use server-driven UI so that the app would fetch its configuration from the server. This article discusses the Screenflow project and how Uber built an interactive UI that could be updated at any point.

Researchers at Google Brain have open-sourced the Switch Transformer natural-language processing AI model.
