Prompt Engineering

Now that we have prepared our data, we are ready to communicate with our model. A Large Language Model is an incredibly knowledgeable yet literal computational system. Unlocking its full potential requires providing instructions—prompts—that are clear, precise, and well structured. Prompt Engineering is the essential science of crafting these inputs to guide the LLM toward generating the specific, high-quality output we desire. Unlike fine-tuning, which modifies the model's parameters, prompt engineering focuses on optimizing the input to the model, often providing the fastest route to improving performance for particular tasks. In this chapter, we will explore the fundamental techniques used to master this art of instruction.
