3.3 How ChatGPT Works

ChatGPT is a chatbot built on top of a large language model. When you type a message (a prompt), it converts your words into numbers, runs them through the model, and predicts a helpful reply word by word. It also remembers the earlier messages in the same conversation, so it can stay on topic.

For example, a student in Bahir Dar can ask, "Explain photosynthesis simply, then give one example." ChatGPT reads the whole request, keeps it in mind, and produces a clear two-part answer — and you can then say "make it shorter" and it will adjust.
