Prompt engineering is the art of crafting precise inputs to get the best results from large language models. Learn core principles like few-shot prompting, chain-of-thought, and RAG-and how small changes in wording can dramatically improve AI output.
Few-shot prompting boosts LLM accuracy by 15-40% using just 2-8 examples. Learn the patterns that work, when to use them, and how they beat fine-tuning in cost and speed.
