What is Prompt? Instructions on how to write an effective Prompt

What is Prompt ? This is a familiar term as artificial intelligence becomes more and more popular in everyday life. In the article below, 1C Vietnam will provide complete information about the concept, role, common types of Prompt as well as how to write effective Prompt. Refer now.

1. What is Prompt?

Prompts are instructions, questions, or requests that humans give to an AI system to get an appropriate response. Simply put, these are “prompts” or “commands” that a user sends to an AI to specify the task the user wants the AI to perform.

Prompts act as a communication bridge between humans and computers, allowing humans to communicate their wishes and receive appropriate results. For example, when a user asks ChatGPT to “Explain how solar energy works in plain language”, this is a prompt. Based on this prompt, the AI will understand the task and generate appropriate content.

2. Common types of Prompts

To use prompts effectively, users need to understand the different types of prompts and the characteristics of each type.

2.1. Classification by purpose of use

Each type of prompt serves a different purpose and requires a different approach. Depending on the intended use, prompts can be divided into different types.

  • Question-Answer Prompts are the simplest type, primarily for asking questions and getting answers, like "What is the capital of Brazil?".
  • Content Generation Prompts focus on generating new content, for example "Write a poem about autumn in Hanoi with a nostalgic tone".
  • Analytical Prompts ask the AI to analyze data or information, such as "Analyze the pros and cons of remote work for tech companies."

2.2. Classification by structure

Structurally, prompts can be classified into several types.

  • Simple Prompts are short, simple commands like "Write a short story about friendship."
  • Multi-part Prompts are more complex, consisting of multiple requests or instructions, such as "Write a marketing email about product X, emphasizing 3 key benefits, about 300 words long, and ending with a compelling call-to-action."
  • Instructional Prompts focus on guiding the AI to perform a specific task in certain steps, for example "Please analyze the following paragraph in three steps: identify the main idea, list supporting arguments, and evaluate the logic of the argument."

2.3. Classification by application field

Prompts can also be classified according to specific application areas.

  • In technology, prompting often involves writing code, explaining technical concepts, or designing systems.
  • In education, prompts focus on explaining knowledge, creating assignments, or assessing students.
  • Marketing uses prompts to create advertising content, analyze markets, or develop marketing strategies. Human resources uses prompts to draft job descriptions, review resumes, or design training programs.

3. Benefits of using Prompt properly

When using prompt effectively, users will receive many significant benefits in work and life.

3.1. Improve work efficiency

Proper use of prompts can save significant time in many daily activities. According to a McKinsey study, professionals who use AI with good prompts can save up to 30% of their weekly work time.

Quality prompts also help increase the accuracy of AI responses. Instead of constantly needing to adjust or request rework, a well-designed prompt can help AI understand the user’s request accurately from the start, minimizing editing time and optimizing workflow.

3.2. Maximize creative potential

Prompts are not only a tool for performing simple tasks, but can also stimulate creativity. A well-designed prompt can open up new ideas that users might not have thought of before, expanding their horizons and breaking the limits of thinking.

Many content creators have turned to prompt as a virtual co-worker, helping them brainstorm ideas, overcome low points of inspiration, and explore new approaches to creative projects.

3.3. Improve user experience with AI

High-quality prompts help AI better understand the user's specific context, goals, and needs. This results in a smoother and more natural experience interacting with AI, closer to conversing with a real colleague.

As users understand how to build effective prompts, they also develop a more productive relationship with AI tools, feel more confident in using them, and leverage the technology’s full potential.

4. How to write effective Prompts

To get the most out of prompts, users need to master the principles and techniques of writing effective prompts.

4.1. Basic principles when writing Prompt

When writing a prompt, follow a few basic principles. First, make sure the prompt is clear and specific. Instead of writing “Write about marketing,” write “Explain 5 effective content marketing strategies for small businesses in the organic food industry.”

Providing full context is also important – AI can’t read your user’s mind. If the user needs a response in a specific format, make that clear in the prompt.

For example: "Write a polite rejection email to an unqualified candidate, using a professional tone and keeping it to 150 words."

4.2. Detailed steps to write a good Prompt

To write an effective prompt, follow these steps:

Step 1: Define the use case: First, clearly define what the user wants to achieve from the AI. This is the most important step, as it will guide the user’s entire approach.

Step 2: Choose the right content type: Based on the purpose, determine the type of content needed (text, list, table, etc.) and inform the AI in the prompt.

Step 3: Write a short but complete command: Combine all of the above elements into a clear, concise but still informative prompt. Avoid prompts that are too long and complicated, but don't be too vague either.

Step 4: Use appropriate keywords and structure: Words like “analyze,” “compare,” “list,” “explain” will help AI understand exactly what type of response the user wants.

Step 5: Test and Adjust: Evaluate initial results and adjust the prompt if necessary. Prompt refinement is an iterative process to achieve optimal results.

5.3. Illustrative examples of how to write effective Prompts

Here's an example of how to move from a less effective prompt to a better one:

Poor prompt: "Write about artificial intelligence."

Good prompt: "Write a short introduction (about 500 words) about the impact of artificial intelligence on the healthcare industry over the past 5 years. The article should include 3 specific examples of successful AI applications in medical diagnosis, written in an informative tone and understandable to non-specialist readers."

Compared to the first prompt, the second prompt provides specific information about length, topic, structure, tone, and target audience, helping the AI generate much more relevant content than the first prompt's vague request.

5. Common mistakes when using Prompt

To avoid unexpected results, pay attention to common mistakes when using prompt.

5.1. Common mistakes to avoid

One of the most common mistakes is writing a prompt that is too vague, without providing enough information or context. For example, if a user simply writes “Write a great blog post,” the AI won’t have enough information to generate content that matches the specific need.

Another mistake is writing a prompt that is too long and complicated, making it difficult for the AI to grasp the main request. A long prompt does not necessarily make a good prompt - what is important is that the content of the prompt is clear and structured.

Many people also forget to test their results before using them. AI is not perfect and can make mistakes, so reviewing and evaluating feedback is an important step in the AI adoption process.

5.2. Consequences of using Prompt ineffectively

Using a poor-quality prompt can have a number of negative consequences. First, users waste time by constantly having to make adjustments and ask the AI to redo. Additionally, the generated content may be inaccurate or irrelevant, forcing users to make extensive revisions or even start over.

In a business environment, poor prompting can lead to poor decisions based on inaccurate information. For new AI users, poor initial experiences can reduce trust in the technology and limit the widespread adoption of potentially powerful tools.

6. FAQ: Frequently asked questions about Prompt

To clarify what prompt is , 1C Vietnam has answered in detail frequently asked questions about prompt.

6.1. Is Prompt only applicable to ChatGPT?

No, the concept of prompting is not limited to ChatGPT. Prompting is used in many different AI models like DALL-E (image generation), Midjourney, Stable Diffusion, and even Google's AI systems like Bard. Each model may have its own approach to prompting, but the basic principle remains the same.

6.2. What is prompt engineering?

Prompt engineering is the process of designing, optimizing, and fine-tuning prompts to interact efficiently with large language models (LLMs). It is a rapidly growing field that combines knowledge of linguistics, psychology, and computer science.

This skill is increasingly valued in the job market, with many new "Prompt Engineer" positions appearing at major technology companies.

6.3. Which areas apply this technology the most?

Prompt is widely used in many different fields. Marketing and content creation are the fields that use prompt the most to create advertisements, blog posts, or social media content. Software development is also an important field, with developers using prompt to write code, debug, or create technical documentation.

Education and research are also actively adopting prompts to create learning materials, analyze research data, or synthesize scholarly literature. Healthcare has begun to use prompts to aid in medical data analysis, summarize patient records, or even aid in initial diagnosis.

6.4. How is a simple prompt different from a multiple prompt?

Simple prompts are typically short, direct, and contain only a single request. For example: “Explain the concept of blockchain in 100 words.” This type of prompt is easy to write and is suitable for simple tasks that do not require a lot of detail or instructions.

In contrast, prompts are often more complex, consisting of multiple requests or steps. For example: "Write a blog post about blockchain that includes five parts: concept introduction, history, how it works, current applications, and future prospects. Each part is about 200 words long, uses beginner-friendly language, and includes examples to illustrate each part." Prompts often help users get more detailed and specific results, but require better prompt writing skills to avoid confusing the AI.

What is a prompt is not just a simple question but a door that opens a new world of possibilities in interacting with AI. From understanding the concept, classification, to mastering effective prompt writing techniques, all help to maximize the potential of AI technology in work and daily life. As the world becomes increasingly digital, the ability to communicate effectively with AI through prompts will become an essential skill for the future.
