プロンプトエンジニアリングとは、AIモデル(特にLLM)から良い結果を得るために効果的なプロンプト(指示/入力)を作成する手法です。LLMは自然言語のプロンプトに応答するため、プロンプトの書き方が出力の品質に大きく影響します。
プロンプトエンジニアリングとは
PROMPT ENGINEERING → designing the input (PROMPT) you give an LLM to get the desired output:
→ LLMs respond to instructions in natural language → the prompt shapes the response
→ better prompts → better, more relevant, accurate results
→ no coding needed → you communicate with the model through well-crafted text
→ a key skill for effectively using LLMs
基本的なテクニック
✓ BE CLEAR and SPECIFIC → state exactly what you want (vague prompts → vague results)
✓ Give CONTEXT → background info the model needs to respond well
✓ Specify FORMAT → ask for the output format you want (list, JSON, steps, length)
✓ Provide EXAMPLES (few-shot) → show examples of the desired input/output → guides the model
✓ Assign a ROLE → 'You are an expert...' → frames the response
✓ Break down COMPLEX tasks → step by step; 'think step by step' (chain of thought)
✓ ITERATE → refine the prompt based on results
