This topic falls under the “Implement generative AI apps and agents by using Foundry” section of the AI-901 exam objectives.

What Is a Prompt?

A prompt is an instruction or input provided to a generative AI model.

Prompts guide the model’s response and influence:

  • Content
  • Tone
  • Format
  • Style
  • Accuracy
  • Level of detail

The quality of the prompt strongly affects the quality of the output.

What Is Prompt Engineering?

Prompt engineering is the process of designing and refining prompts to improve AI-generated responses.

Effective prompt engineering helps:

  • Produce more accurate answers
  • Reduce ambiguity
  • Improve consistency
  • Control response format
  • Reduce hallucinations
  • Improve safety and Responsible AI behavior

Types of Prompts

For the AI-901 exam, two important prompt types are:

  • System prompts
  • User prompts

What Is a System Prompt?

A system prompt provides high-level instructions that define how the AI model should behave.

System prompts often control:

  • Personality

What Is a User Prompt?

A user prompt is the direct request or question submitted by the user.

User prompts specify the task the model should perform.

Example of a User Prompt

“How do I reset my router?”

The AI model combines:

  • System instructions
  • User request
  • Context information

to generate a response.

Relationship Between System and User Prompts

System prompts establish behavior rules, while user prompts define the immediate task.

Example

System Prompt

“You are a helpful travel assistant. Always provide answers in bullet points.”

User Prompt

“Suggest three family-friendly attractions in Orlando.”

The model responds according to both prompts.

Characteristics of Effective Prompts

Good prompts are usually:

  • Clear
  • Specific
  • Contextual
  • Structured
  • Goal-oriented

Clear Prompts

Clear prompts reduce confusion and ambiguity.

Weak Prompt

“Tell me about databases.”

Better Prompt

“Explain the differences between relational and non-relational databases for beginners.”

The second prompt provides:

  • Specific topic
  • Audience
  • Scope

Specific Prompts

Specific prompts improve response accuracy.

Weak Prompt

“Write a report.”

Better Prompt

“Write a 300-word summary of cloud computing benefits for small businesses.”

Specific prompts define:

  • Length
  • Topic
  • Audience

Providing Context

Context helps the model generate more relevant answers.

Example

“I am studying for the AI-901 exam. Explain OCR in simple terms with one real-world example.”

The additional context improves response quality.

Requesting Output Format

Prompts can specify desired formatting.

Example

“Provide the answer as a table.”

or

“Summarize the information in bullet points.”

Role Prompting

Role prompting assigns the AI a specific role or perspective.

Example

“Act as a cybersecurity consultant.”

or

“You are an experienced data analyst.”

Role prompting helps guide tone and expertise.

Step-by-Step Prompting

Prompts can request step-by-step explanations.

Example

“Explain how machine learning works step-by-step for beginners.”

This improves clarity and educational usefulness.

Few-Shot Prompting

Few-shot prompting provides examples within the prompt.

This helps the model understand expected patterns.

Example

Positive review → Positive sentiment
Negative review → Negative sentiment
“The service was excellent.” →

The model learns the desired output structure.

Zero-Shot Prompting

Zero-shot prompting asks the model to perform a task without examples.

Example

“Classify this review as positive or negative.”

Chain-of-Thought Prompting

Chain-of-thought prompting encourages step-by-step reasoning.

Example

“Explain your reasoning step-by-step before providing the final answer.”

This can improve reasoning accuracy for complex tasks.

Prompting for Summarization

Generative AI models can summarize content using prompts.

Example

“Summarize this article in three bullet points.”

Prompting for Content Generation

Prompts can generate new content such as:

  • Emails
  • Reports
  • Stories
  • Marketing copy
  • Code

Example

“Write a professional email requesting a project update.”

Prompting for Transformation Tasks

AI models can transform content into different formats.

Examples

  • Translate text
  • Rewrite text
  • Simplify technical content
  • Convert paragraphs into tables

Example

“Rewrite this paragraph for a non-technical audience.”

Prompting for Code Generation

Generative AI can assist with programming tasks.

Example

“Write a Python function that calculates sales tax.”

Prompting for Data Extraction

Prompts can request structured data extraction.

Example

“Extract all dates and company names from this document.”

Prompt Injection Risks

Prompt injection occurs when users attempt to override system instructions.

Example

A malicious user prompt may attempt to bypass safety rules.

Organizations should implement safeguards against unsafe prompting behavior.

Responsible AI Considerations

Effective prompting should follow Responsible AI principles.

Important considerations include:

  • Safety
  • Fairness
  • Privacy
  • Transparency
  • Content moderation
  • Harm prevention

Hallucinations

Generative AI models can sometimes produce incorrect or fabricated information.
