“In the symphony of the AI ​​era, the prompt engineer is the silent but crucial conductor, using carefully woven language to guide the intelligent behemoth of the big model to create the miracle of human thinking.

Since the birth of the new production paradigm, I have added a new identity to my job - prompt engineer.

I shuttled between different large language models, seeking resonance, and studied various prompt word paradigms, trying from few-shot, COT, self-consistency to dynamic prompt words. I once installed an x ​​to do a prompt word engineering training for the company, trying to transfer the pain and happiness of writing prompt words to everyone.

However, after dealing with it for a while, I found that there is still a language barrier between people and the big model - you don’t know me and I don’t know you.

In fact, we usually use more domestic models, especially before DeepSeek was born. Zhipu and Qianwen were used in production environments. The various prompts for chatgpt claude circulating on the Internet are really not that applicable. I often spent half a day and still couldn't generate the desired effect.

My friend next door once said with emotion: "After spending half a day chatting with LLM, I finally felt that we were on the same wavelength."

Sometimes I have to write more than a dozen tasks a day (yes, that's the intensity, I'm not afraid of rushing out a system in two or three days). I get several chicken legs a day.

Finally one day, I couldn't stand it anymore and I rebelled. I wanted to get rid of these days of being enslaved by big models!

Let AI generate prompt words

Previously, a team in Singapore proposed the CO-STAR framework, which has a good idea, but there are still too many words to write. As for the prompt word issue, the large language model can solve it by itself!

The following is a useful prompt word structure that I frequently use in multiple projects :

1. Role

The big model needs to play an identity or position.

2. Objective

What is the core objective of the mission?

3. Constraints

What are the hard requirements or restrictions?

4. Workflow

What steps should be followed to execute the task?

5. Example

Provide specific examples to ensure that the output style meets expectations.

Based on the above structure, I created a tool to automatically generate coze prompt words. I provide it to everyone for use (the qwen-max model is used by default)

https://www.coze.cn/store/project/7484301292970672179?from=store_search_suggestion&bid=6fnco0ods7g1j 

Just enter the task you want to perform in the task description. For example, "Enter a user question and generate the corresponding MYSQL query statement." Then click [Button] (what a straightforward logo)

The process behind this is as follows

Will it be expensive to frequently call on large models?

It seems that the large language model is frequently called in the process, but don’t forget that the billing of the large model is calculated based on tokens (simply understood as the number of words). In fact, although there are many processes, there are not many tokens.

Additionally, having large models focus on one task at a time often produces better results.

It turns out that being loyal is indeed more charming.

Let’s see it in action

The following case explains why the prompt word generation tool is more useful.

Enter a task description:

Please help me generate a 300-word copy for the power bank that supports super-fast charging produced by Beta.

Throw this task description into the prompt word automatic generation tool and let it generate the prompt word by itself:

## Role

Copywriting Expert

##Goal

Generate a 300-word copy for Beta Company’s power bank that supports super-fast charging.

## Constraint

1. The copy should be within 300 words and be concise and clear.

2. Highlight the core selling point of the product: support for super fast charging.

3. Emphasize the portability and efficiency of the product.

## Workflow

1. Clarify the core selling point of the product: a power bank that supports super-fast charging.

2. Identify the target audience: mobile device users who need fast charging.

3. Highlight product advantages: fast charging speed, strong portability and high safety.

4. Emphasize user experience: save time, charge anytime and anywhere, and easy to use.

5. Describe the product details: capacity, charging speed, compatible devices, appearance design.

6. Use eye-catching titles: for example, "Beta Super Fast Charging Power Bank: Ultra-fast charging, a source of energy anytime, anywhere."

7. Introduce the problem at the beginning: The fast pace of modern life and the problem of low battery in mobile phones.

8. Provide a solution: How does Beta Super Fast Charging Power Bank solve this problem?

9. Use specific data: for example, "50% battery charge in 30 minutes".

10. Emphasis on safety: multiple protection mechanisms ensure safe use.

11. Description Portability: Lightweight design, easy to carry.

12. Mention compatibility: support for multiple devices, such as mobile phones, tablets, headphones, etc.

13. Ending call to action: Encourage users to buy now and enjoy the convenience of fast charging.

14. Ensure that the copy is fluent: the logic is clear, the language is concise, and it is easy to understand.

15. Final check: Make sure there are no grammatical errors and the information is accurate.


The copywriting results of the large model are directly input with the original task description:

The new super-fast charging power bank launched by Beta redefines the speed and convenience of mobile charging. This power bank uses the latest super-fast charging technology and supports a charging power of up to 100W. It only takes 15 minutes to replenish the power needed for your device for a day, allowing you to enjoy worry-free power anytime, anywhere.

The product has a built-in smart chip that can automatically identify the device type and match the best charging solution to ensure an efficient and safe charging experience. At the same time, it also has multiple protection functions, including overvoltage, overcurrent, short circuit and temperature control, to fully protect the safety of you and your device.

In terms of appearance design, this power bank adopts lightweight materials and simple style, weighing less than 300 grams, which is easy to carry. Its surface is finely frosted, comfortable to touch, non-slip and durable.

Whether you are traveling or working, Beta Super Fast Charger can be your reliable energy partner. Let every moment be full of energy and under control!


The copywriting effect of inputting the prompt words generated by the prompt word generation tool into the large model:

**Beta Super Fast Charger: Ultra-fast charging, a source of energy anytime, anywhere**

Modern life is fast-paced, and low battery on mobile phones has become a problem for many people. Have you ever been anxious because of running out of battery? Beta Super Fast Charge Power Bank can help you solve this problem!

The copy generated after the blessing is developed in the order of "problem-solution-product features-usage scenarios-summary and appeal". The structure is indeed clear and smooth, and easier to understand . It also makes me feel more emotional when reading it . There is also a call to action at the end , which helps promote conversion.

Last words

At the boundary of AI and human communication, prompt engineering is not only a translator of language, but also a transmitter of thought. When we learn to let AI write for AI, we actually enter the field of meta-prompt engineering, truly playing with technology, rather than being played by technology. Prompt word engineering may eventually die out, but at present, the ability to think about how to guide machines to think is still a core quality that everyone must have to improve productivity in the AI ​​era.
