Few-Shot Prompting: Learning from Examples

Master few-shot prompting by showing AI examples of desired output. Learn to create consistent, high-quality results through example-based learning.

What is Few-Shot Prompting?

Few-shot prompting involves providing AI with a few examples of the desired input-output pattern before asking it to perform the task. This technique helps ensure consistent formatting and style.

Why Use Few-Shot?

  • ✅ Ensures consistent output format
  • ✅ Shows exact style and tone
  • ✅ Reduces ambiguity
  • ✅ Improves first-try accuracy

Basic Few-Shot Example

Product Description Format

Create product descriptions following this format: **Product**: Wireless Headphones **Description**: Premium over-ear headphones with noise cancellation **Price**: $199 **Key Features**: 30-hour battery, quick charge, premium sound **Product**: Smart Watch **Description**: Fitness-focused smartwatch with health monitoring **Price**: $299 **Key Features**: Heart rate monitor, GPS, waterproof Now create a description for: Bluetooth Speaker

Best Practices

Example Quality

  • • Use 2-5 high-quality examples
  • • Show variety within consistency
  • • Include edge cases if relevant
  • • Make patterns clear

Format Guidelines

  • • Keep same structure across examples
  • • Clearly separate examples
  • • Mark where examples end
  • • Be explicit about the task

Common Use Cases

  • Data formatting: Converting data to specific structures
  • Content creation: Maintaining consistent style and tone
  • Classification: Categorizing items consistently
  • Email templates: Professional communication patterns
  • Code generation: Following specific coding patterns

Email Classification Example

Classify emails as URGENT, IMPORTANT, or ROUTINE: Email: "Server down - all customers affected" Classification: URGENT Reason: Service outage impacting customers Email: "Quarterly review meeting next week" Classification: IMPORTANT Reason: Scheduled business meeting Email: "Office coffee machine maintenance" Classification: ROUTINE Reason: Regular facility maintenance Now classify: "Security breach detected"

Tips for Success

  • Quality over quantity: 3 great examples beat 10 poor ones
  • Show edge cases: Include unusual but valid examples
  • Be consistent: Follow the same pattern in all examples
  • Clear boundaries: Make it obvious where examples end
