I feed it the api documentation for multiple non public apis documentation and ask it to make a script that combines them and it nails it. It’s not that it can write code to do a thing, it’s that it can write code that combines them and puts them together in a new way.

Last night I used gpt3 to write an app that lets me describe apps I want and then it writes them complete with gui and lets me run them. Simple utility type apps, but still. It works.
