Prompt engineering
Prompt engineering is a technology that designs instructions given to AI to obtain the desired answer.
Prompt engineering is a technology that systematically designs and refines instructions to reliably obtain answers of the desired quality from AI. When entrusting a job to a competent but unfamiliar new employee, it can be compared to writing a work instruction that clearly writes down the background explanation, examples, and result format.
As it became known that the quality of AI answers greatly depends on the instructions, it has become a practical skill. Techniques such as assigning roles, presenting examples (few shots), and inducing step-by-step thinking are representative techniques, and in the development field where AI services are created, product quality is determined in the form of system prompt design.
As models become smarter, the effectiveness of complex techniques tends to decrease, and the view that the ability to clearly organize requirements rather than technique is the essence in the long run is gaining ground.
✅ Why it matters
- You can obtain much more accurate and useful results with the same AI
- It is the cheapest way to increase the level of AI utilization without separate development
- It is a key task that determines product quality in AI service development
⚠️ Limits and debates
- When the model changes, prompts that worked well may not work
- Often relying on intuition without systematic verification
- As model performance improves, the importance of detailed techniques gradually decreases.
