Interacting with APIs is the old style. The magic of ChatGPT is the same magic as google had back in the day - you ask it in plain english and it has an answer.

I'm guessing the solution looks like a model trained to take actions on the internet. Kinda sucks for those of us on the outside, because whatever we make is going to be the same, brittle, chewing-gum and duct tape approach as usual. Best to wait for the bleeding edge, like what that MinecraftGPT project was aiming at.
