Now that you understand the fundamentals of prompt engineering, let's dive into the core prompting techniques that will form the foundation of your prompt engineering skills.
What You'll Learn
By the end of this lesson, you'll be able to:
- ✅ Master zero-shot, one-shot, and few-shot prompting techniques
- ✅ Apply chain-of-thought prompting for complex reasoning
- ✅ Use multimodal prompting with images and text
- ✅ Implement function calling and RAG techniques
- ✅ Choose the right technique for different scenarios
Zero-Shot Prompting
Zero-shot prompting is when you ask an AI to perform a task without providing any examples. The model relies entirely on its pre-trained knowledge.
When to Use Zero-Shot
- Simple, straightforward tasks
- Common knowledge questions
- Basic text generation
- When you want quick results
Examples
Direct instruction for content categorization
Direct instruction for code analysis
Direct instruction for data interpretation
One-Shot Prompting
One-shot prompting provides a single example to guide the AI's response. This helps the model understand the expected format and style.
When to Use One-Shot
- When you need specific formatting
- For tasks that benefit from examples
- When zero-shot isn't giving desired results
- To establish a particular style or tone
Examples
One example to establish email format and tone
One example to establish code structure and style
Few-Shot Prompting
Few-shot prompting provides multiple examples to establish a clear pattern. This is especially effective for complex tasks or when you need consistent formatting.
When to Use Few-Shot
- Complex tasks requiring multiple examples
- When you need consistent output format
- For tasks with multiple possible approaches
- When one-shot isn't sufficient
Examples
Multiple examples to establish sentiment analysis pattern
Multiple examples to establish problem-solving pattern
Chain-of-Thought Prompting
Chain-of-thought (CoT) prompting encourages the AI to show its reasoning process step by step. This is particularly useful for complex problem-solving tasks.
When to Use Chain-of-Thought
- Complex reasoning problems
- Mathematical calculations
- Logical puzzles
- When you want to understand the AI's thinking process
- Debugging and troubleshooting
Examples
Step-by-step reasoning for complex calculations
Step-by-step logical analysis
Advanced Prompting Techniques
Multimodal Prompting
Multimodal prompting involves using multiple types of input (text, images, audio, video) to get more comprehensive responses from AI models.
When to Use Multimodal
- When you need to analyze visual content
- For tasks requiring both text and image understanding
- When working with documents, charts, or diagrams
- For creative tasks involving multiple media types
Examples
Multimodal prompt combining text and image input
Multimodal prompt for document processing
Function Calling
Function calling allows AI models to execute specific functions or API calls based on your prompts, enabling more interactive and dynamic responses. The Model Context Protocol (MCP) provides a standardized approach to function calling across different AI platforms.
When to Use Function Calling
- When you need real-time data
- For tasks requiring external API integration
- When you want the AI to perform actions
- For dynamic content generation
Examples
Function calling for real-time weather data
Function calling for live market data
RAG (Retrieval-Augmented Generation)
RAG combines AI generation with external knowledge retrieval, allowing models to access up-to-date information beyond their training data.
When to Use RAG
- When you need current information
- For domain-specific knowledge
- When working with proprietary data
- For tasks requiring recent events or data
Examples
RAG for accessing current research data
RAG for accessing company knowledge base

Best Practices for Each Technique
Zero-Shot Best Practices
- Be very specific about what you want
- Use clear, unambiguous language
- Consider the model's knowledge cutoff
- Test with different phrasings
One-Shot Best Practices
- Choose a representative example
- Ensure the example matches your desired output format
- Keep examples concise but complete
- Use examples that demonstrate the right level of detail
Few-Shot Best Practices
- Provide 2-4 examples for best results
- Ensure examples are consistent in format and style
- Vary the examples to show different scenarios
- Make sure examples are relevant to your task
Chain-of-Thought Best Practices
- Explicitly ask for step-by-step reasoning
- Use phrases like "Let's solve this step by step" or "Think through this"
- Provide enough context for the reasoning process
- Be patient with longer responses
Practice Exercises
Exercise 1: Zero-Shot
Ask an AI to explain a complex concept in simple terms
Exercise 2: One-Shot
Create a template for writing product reviews
Exercise 3: Few-Shot
Create a pattern for generating headlines
Exercise 4: Chain-of-Thought
Solve a logic puzzle with step-by-step reasoning
Common Pitfalls to Avoid
- Inconsistent Examples: Make sure your few-shot examples follow the same pattern
- Overly Complex Prompts: Start simple and add complexity as needed
- Ignoring Context: Provide enough context for the AI to understand the task
- Unrealistic Expectations: Don't expect perfect results from basic techniques alone
- Poor Formatting: Use clear formatting to separate examples and instructions
