The pieces in human terms
-
Interface
The doorway: chat, search, IDE, office app, image tool, API, phone assistant, or product feature.
-
Prompt
The instruction plus context, files, screenshots, code, history, and desired format.
-
Model
The trained engine that predicts useful output based on patterns, instructions, and context.
-
RAG
Retrieval-augmented generation: pulling source material into the prompt so the answer has something real to stand on.
-
Tools
Search, calculators, file readers, code runners, APIs, email/calendar actions, and other controlled abilities.
-
Feedback
The loop where people correct, refine, reject, steer, and improve the next turn.
