[D]: What does Replika exactly consist of? (besides GPT-neo)

I just wondered, besides the visual stuff, how does this chatbot work.
Theres unmaintained libraries like cakechat on replika's github, but if someone could break down replika to its core components that would be fine.

I imagine something like this:

* for loop to accept users input
* something to transform the input into something else better used for GPT-neo (what?)
* gpt-neo generator
* something to transform the output into something suitable for the user (what?)

how do those …
