The importance of mastering writing ChatGPT prompts

In the world of artificial intelligence, “Prompt Engineering” has become an essential skill. For what ? Because the quality of your interaction with ChatGPT largely depends on the quality of your instructions.

A well-written prompt can make the difference between a vague answer and a precise answer. It can affect how quickly you get information and also how much information you get.

The advantages of a well-written message

  1. Accurate results : A clear and concise prompt provides clear and concise answers. This means less time spent interpreting answers or asking follow-up questions.
  2. Efficiency : With a well-written message, you get what you want the first time. This means fewer requests, less time spent waiting, and a better overall experience.
  3. Cost reduction : Fewer queries mean less cost. If you pay per query, this can add up quickly.

The 3 ingredients of a perfect promptT

There are three key elements to consider when writing a prompt for ChatGPT:

  1. The context : AI must understand the context to provide a relevant response. The more details you provide, the better.
  2. Task : Be specific about what you want. If you want a list, ask for a list. If you want a detailed explanation, ask for it.
  3. The role : Tell the AI ​​how you want it to respond. Do you want me to become a teacher? An advisor? An expert ? The role can influence the tone and level of detail of the response.

Basic examples to illustrate

1. Ask for general information on a topic

  • Bad suggestion : “Tell me something about cats. »
  • Good suggestion : “As a biology expert, can you give me five scientific facts about domestic cat behaviors? »

2. Find a solution to a specific problem

  • Bad suggestion : “My computer won’t start. »
  • Good suggestion : “As a computer technician, can you walk me through the steps to troubleshoot a computer that won’t start? »

3. Request for opinion or consultancy

  • Bad suggestion : “Should I buy this car?” »
  • Good suggestion : “As an automotive consultant, can you tell me the advantages and disadvantages of buying an electric car versus a petrol car? »

4. Explore a complex topic

  • Bad suggestion : “Tell me about space. »
  • Good suggestion : “As an astrophysicist, can you explain to me the main challenges of colonizing Mars? »

Each good tip above clearly incorporates context, defines the intended task, and assigns a specific role to the AI. These elements combined allow you to get more accurate and relevant responses from ChatGPT.


Writing instructions for ChatGPT is an art and a science. With practice, you can perfect your skills and achieve even better results with your favorite AI. By understanding the basics of writing prompts, you’ll be on your way to maximizing ChatGPT’s potential.
