How Does ChatGPT Work?

ChatGPT predicts the next token based on patterns learned during training. It does not "think" in the human sense and does not verify facts in real time unless connected to tools.

Because language models optimize probability, they can produce fluent but incorrect statements. This is why source checks and citation review remain mandatory for serious writing.

Prompt quality, context length, and revision loops have a direct impact on output quality. Better instructions usually mean fewer generic or repetitive phrases.

For school and professional writing, treat ChatGPT as a drafting assistant and reserve final authority for human editing.
