Prompt engineering is the practice of designing your instructions so a large language model reliably produces the result you want. With the same model, someone who asks well can easily get ten times better output than someone who does not.

Why Prompts Matter So Much

An LLM works by predicting the next token from the context it is given. The clearer that context, the less room the model has to guess. Writing a prompt is like briefing a brilliant new hire who knows nothing about your business: you have to explain the background, the goal, the requirements, and the standards.
