can you do video tutorial for codes that act (may be via function calling), instead of just returning data? for example, GUI navigation, web browsing etc

[zainn]

[farhanafridi]

Solid content!

I have two questions;

1) Can we add memory in the RAG code that you showed in the video?

2) Can we use agents through LCEL syntax?

[GulshanSaini]

How you get that crystal clear voice. What is your recording setup?

USER_AGENT environment variable not set, consider setting it to identify your requests.

[rifazjeoffrey]

Does changing the prompt return different answers? What will be a good prompt for a RAG app?
