Master Prompt Engineering Techniques for Better AI Output

Written by

Introduction When considering the input and output of a large language model, a text prompt (sometimes along with other formats like image prompts) serves as the input that the model utilizes to generate a specific output. You don’t have to be a data scientist or a machine learning expert – anyone can create a prompt. Nonetheless, developing the most effective prompt can be challenging. Numerous factors influence the effectiveness of your prompt: the model you select, the data on which the model was trained, the configurations of the model, as well as your choice of words, style, tone, structure, and context all play a significant role.

Consequently, prompt engineering is a process that requires iteration. Poorly constructed prompts can result in vague or erroneous responses and can obstruct the model’s capability to deliver valuable output. When interacting with the Gemini chatbot, you are essentially crafting prompts; however, this whitepaper emphasizes prompt creation for the Gemini model within Vertex AI or through the API, as directly prompting the model allows you to access configurations like temperature, etc. This whitepaper provides a comprehensive overview of prompt engineering.

We will explore various prompting techniques to help you get started and offer tips and best practices to enhance your skills as a prompting expert. Additionally, we will examine some of the challenges you may encounter while designing prompts. Read the whitepaper below.

What Are Prompt Engineering Techniques?

Prompt engineering techniques are strategies used to create better inputs (prompts) for large language models like ChatGPT or Gemini. These models generate responses based on the input they receive. The better your prompt, the more accurate and useful the response.

Think of it like giving clear instructions to a very smart assistant. If you’re vague, the assistant guesses. If you’re specific, it delivers exactly what you need.

Why Are Prompt Engineering Techniques Important?

Here’s why these techniques are critical:

  • They improve model accuracy and reduce confusion.

  • They save time and money by reducing trial-and-error.

  • They help customize outputs to your exact needs.

  • They make LLMs usable by non-programmers.

With prompt engineering techniques, you guide the AI’s reasoning and output style more effectively.

Types of Prompt Engineering Techniques

Zero-shot Prompting

This is the simplest technique. You give the model a task without any examples.

Prompt: "Classify this review as positive, neutral, or negative: 'The movie was intense and thoughtful.'"

Useful when you want quick responses without needing examples.

One-shot and Few-shot Prompting

This technique includes one or more examples to show the AI what kind of output you expect.

Prompt:
"Example: 'The pizza was amazing!' → Positive
Now classify: 'It was fine, but not great.'"

Few-shot works best when your task requires pattern recognition or structure.

Role-based Prompt Engineering Techniques

In this method, you assign a role to the AI like “act as a travel guide” or “act as a math tutor.” It helps shape tone and detail.

Prompt: "You are a cybersecurity analyst. Analyze this email for threats."

Role prompting makes outputs more relevant and context-aware.

System and Contextual Prompting

System prompts define overall behavior, while context prompts give task-specific details.

Example system prompt: “Always respond in JSON format.” Example context prompt: “This is for a blog about 80s arcade games.”

Combining both ensures structured and accurate results.

Chain-of-Thought Prompting

This method helps AI solve problems step-by-step.

Prompt: "I was 3, my partner was 3 times my age. I’m 20 now. How old is my partner? Think step by step."

It’s great for reasoning and math-based tasks.

How to Use Prompt Engineering Techniques Effectively

Here are some best practices:

🔹 Keep Prompts Clear and Simple

Avoid confusing language. Use direct commands like:

  • “Write a blog post”

  • “Summarize this paragraph”

  • “Translate this text”

🔹 Add Examples When Needed

One or two examples often boost accuracy. Especially helpful in content generation or data extraction.

🔹 Control Output with Variables and Instructions

Use placeholders like {topic} or {city} to reuse prompts. Also, give clear instructions such as:

  • “Limit response to 100 words”

  • “Use formal tone”

🔹 Fine-tune Model Settings

Adjust output with these controls:

  • Temperature: randomness of answers

  • Top-K / Top-P: variety of word choices

  • Max tokens: length of output

Advanced Prompt Engineering Techniques

Step-back Prompting

Ask a general question first, then go specific. Helps AI focus on broad context before solving the task.

Tree-of-Thought (ToT)

AI explores multiple reasoning paths like a decision tree. Ideal for complex problem-solving.

ReAct (Reason + Act)

The AI reasons, performs actions (like API calls), and adjusts its thinking. Great for agent-style applications.

Benefits of Using Prompt Engineering Techniques

  •  Higher accuracy

  • Less output hallucination

  • Structured, reusable responses

  • Enhanced user experience

FAQ
