Making communication paths explicit in ChatGPT apps
Be intentional about which communication path handles which interaction in ChatGPT apps.
Explicitly define and be intentional about the different communication paths in ChatGPT apps.
ChatGPT apps involve multiple interaction paths between the widget, server, and model. These paths are not interchangeable and serve different purposes. Making these paths explicit ensures that the correct mechanism is responsible for each part of the user experience.
Distinguish between paths for user input to the model, model output to the UI, and UI state updates that inform the model. Each path should be designed for its specific role.
In ChatGPT apps, make communication paths between the widget, server, and model explicit. Be intentional about assigning specific interaction types to distinct communication mechanisms for a well-defined experience.
