Traditional Developer vs LLM Application
Main Difference Between All the Concepts

Traditional developer: writes the rules the software must follow.
LLM application developer: uses an AI model that has already learned language patterns, then controls it using prompts, context, validation, APIs, and normal application code.

A useful way for developers to remember it

Traditional application:

I tell the computer exactly how to do the task.
Enter fullscreen mode Exit fullscreen mode

LLM application:

I tell the model what I want, provide the necessary context/data, and then verify/control its response.
Enter fullscreen mode Exit fullscreen mode

And in real production systems, you normally use both together:

Traditional Development + LLM = Modern LLM Application
Enter fullscreen mode Exit fullscreen mode
