Describe how generative AI models work (AI-901 Exam Prep)

 
This post is a part of the AI-901: Microsoft Azure AI Fundamentals Exam Prep Hub. 
This topic falls under these sections:
Identify AI concepts and capabilities (40–45%)
   --> Identify AI model components and configurations
      --> Describe how generative AI models work

Note that there are 10 practice questions (with answers and explanations) for each section to help you solidify your knowledge of the material. Also, there are 2 practice tests with 60 questions each available on the hub below the exam topics section.

Generative AI is one of the most important and rapidly growing areas of artificial intelligence and is a major topic for the AI-901 certification exam. Microsoft includes generative AI concepts within the “Identify AI model components and configurations” section of the exam objectives.

Understanding how generative AI models work means understanding how AI systems can create new content such as text, images, audio, code, and video based on patterns learned from large datasets.

What Is Generative AI?

Generative AI refers to AI systems that can generate new content based on patterns learned from training data.

Unlike traditional AI systems that primarily classify or predict, generative AI creates original outputs.

Examples of Generated Content

  • Text
  • Images
  • Music
  • Speech
  • Code
  • Video

Example Applications

  • AI chatbots
  • Image generators
  • Code assistants
  • Content summarization
  • Translation systems
  • Virtual assistants

How Generative AI Differs from Traditional AI

Traditional AIGenerative AI
Classifies or predictsCreates new content
Detects spam emailsWrites emails
Identifies objects in imagesGenerates images
Predicts sales trendsCreates reports or summaries

Traditional AI often answers questions like:

  • “What category does this belong to?”
  • “What will likely happen next?”

Generative AI answers questions like:

  • “Create something new.”
  • “Generate content based on this prompt.”

Foundation Models

Many generative AI systems are built using foundation models.

A foundation model is a very large AI model trained on massive amounts of data that can be adapted for many tasks.

Foundation models learn general patterns in:

  • Language
  • Images
  • Audio
  • Code
  • Knowledge relationships

These models can then be specialized or prompted for different use cases.

Large Language Models (LLMs)

Large Language Models (LLMs) are a type of generative AI model focused on understanding and generating human language.

Examples include systems used for:

  • Chatbots
  • Writing assistants
  • Summarization
  • Translation
  • Question answering
  • Code generation

LLMs are trained using enormous collections of text data from books, articles, websites, and other sources.

How Large Language Models Work

At a high level, LLMs work by predicting the most likely next word or token in a sequence.

Example

If the model sees:

“The sky is…”

It may predict:

“blue”

By repeatedly predicting the next token, the model can generate sentences, paragraphs, and conversations.

Tokens in Generative AI

Generative AI models process information as tokens.

Tokens are small units of text, which may represent:

  • Words
  • Parts of words
  • Characters
  • Punctuation

Example

The sentence:

“AI is powerful”

might be broken into tokens such as:

  • “AI”
  • “is”
  • “powerful”

The model predicts tokens one at a time to generate output.

Neural Networks and Deep Learning

Generative AI models are built using deep learning neural networks.

Neural networks are systems inspired by the structure of the human brain.

These networks contain many layers that learn patterns from data.

Generative AI models often contain:

  • Millions
  • Billions
  • Or even trillions of parameters

Parameters are internal values learned during training that help the model recognize relationships and patterns.

Transformers

Most modern generative AI systems use a neural network architecture called the Transformer.

Transformers are highly effective for processing sequences such as language.

Transformers help models:

  • Understand context
  • Recognize relationships between words
  • Handle long passages of text
  • Generate coherent responses

The Transformer architecture is a foundational technology behind many modern AI systems.

Training Generative AI Models

Training a generative AI model involves exposing it to massive datasets.

During training, the model learns patterns and relationships by repeatedly predicting missing or next tokens.

Simplified Training Process

  1. Provide training data
  2. Hide or predict portions of the data
  3. Compare predictions to actual results
  4. Adjust model parameters
  5. Repeat many times

This process may require enormous computing power and specialized hardware such as GPUs.

Pretraining and Fine-Tuning

Generative AI training often occurs in two stages.

Pretraining

The model learns general knowledge and patterns from very large datasets.

Example

An LLM may learn grammar, facts, reasoning patterns, and language structure from internet-scale text data.

Fine-Tuning

The pretrained model is then adapted for specific tasks or domains.

Example

A healthcare chatbot may be fine-tuned using medical terminology and healthcare conversations.

Fine-tuning improves performance for specialized use cases.

Prompts and Prompt Engineering

Users interact with generative AI systems using prompts.

A prompt is the input or instruction given to the model.

Examples

  • “Write a summary of this article.”
  • “Generate an image of a beach at sunset.”
  • “Explain machine learning simply.”

Prompt engineering refers to designing prompts that produce better outputs.

Well-structured prompts often improve:

  • Accuracy
  • Clarity
  • Relevance
  • Consistency

Temperature and Randomness

Generative AI systems often include configuration settings such as temperature.

Temperature controls randomness in generated responses.

TemperatureBehavior
Low temperatureMore focused and predictable responses
High temperatureMore creative and varied responses

Example

A low temperature may be used for factual responses, while a higher temperature may be used for creative writing.

Hallucinations

Generative AI models can sometimes produce incorrect or fabricated information called hallucinations.

Example

An AI chatbot may confidently provide false information or invent references.

Hallucinations occur because models generate likely patterns rather than verifying factual truth.

This is an important AI-901 exam concept.

Context Windows

Generative AI models use context windows to determine how much information they can process at one time.

The context window includes:

  • User prompts
  • Previous conversation history
  • Uploaded content
  • Instructions

Larger context windows allow models to handle longer conversations and larger documents.

Retrieval-Augmented Generation (RAG)

Some AI systems use Retrieval-Augmented Generation (RAG).

RAG combines:

  • A generative AI model
  • External knowledge retrieval

Instead of relying only on training data, the model retrieves current or domain-specific information before generating responses.

Benefits

  • More accurate responses
  • Reduced hallucinations
  • Access to updated information

Generative AI Modalities

Generative AI is not limited to text.

Different model types generate different content formats.

Model TypeOutput
Text modelsArticles, conversations, summaries
Image modelsPictures and artwork
Audio modelsSpeech and music
Video modelsVideo clips
Code modelsProgramming code

Responsible AI Considerations

Generative AI systems introduce Responsible AI concerns such as:

  • Bias
  • Hallucinations
  • Harmful content generation
  • Privacy risks
  • Copyright concerns
  • Security risks

Organizations should implement:

  • Human oversight
  • Content filtering
  • Monitoring
  • Transparency
  • Governance policies

Azure and Generative AI

Microsoft Azure AI Services and related Azure AI offerings provide tools for building and deploying generative AI applications.

Microsoft also provides Responsible AI guidance and safety controls for generative AI systems.

Real-World Example

Scenario: AI Customer Support Assistant

A company deploys a generative AI chatbot for customer support.

How It Works

  • Users enter prompts
  • The language model processes tokens
  • The transformer architecture analyzes context
  • The model predicts likely responses
  • The chatbot generates natural language answers

Additional Features

  • Fine-tuned on company documentation
  • Uses RAG to retrieve current policy information

Describe considerations for accountability in an AI solution (AI-901 Exam Prep)

 
This post is a part of the AI-901: Microsoft Azure AI Fundamentals Exam Prep Hub. 
This topic falls under these sections:
Identify AI concepts and capabilities (40–45%)
   --> Describe principles of responsible AI
      --> Describe considerations for accountability in an AI solution

Note that there are 10 practice questions (with answers and explanations) for each section to help you solidify your knowledge of the material. Also, there are 2 practice tests with 60 questions each available on the hub below the exam topics section.

Accountability is one of Microsoft’s core Responsible AI principles and an important topic for the AI-901 certification exam. Accountability means that organizations and individuals remain responsible for the design, deployment, operation, and outcomes of AI systems.

Even when AI systems automate decisions or recommendations, humans and organizations are still accountable for how those systems behave and affect people.

What Is Accountability in AI?

Accountability in AI means that organizations must:

  • Take responsibility for AI system behavior
  • Monitor AI systems appropriately
  • Correct problems when issues arise
  • Ensure AI is used ethically and safely
  • Establish governance and oversight processes

AI systems should not operate without human responsibility or organizational oversight.

Why Accountability Matters

AI systems can significantly affect people’s lives in areas such as:

  • Hiring
  • Healthcare
  • Banking
  • Education
  • Insurance
  • Law enforcement
  • Customer service

If an AI system causes harm, produces biased outcomes, or makes incorrect decisions, organizations cannot simply blame the technology.

Humans remain responsible for:

  • Designing the system
  • Choosing training data
  • Setting policies
  • Reviewing outputs
  • Monitoring system performance

Accountability helps ensure organizations use AI responsibly.

Human Responsibility in AI

One of the most important ideas in accountability is that humans remain responsible for AI systems.

AI systems should support human decision-making rather than completely replace accountability.

Example

If an AI system incorrectly denies a loan application, the financial institution remains responsible for addressing the issue.

Organizations cannot avoid responsibility by claiming, “The AI made the decision.”

Governance and Oversight

Organizations should establish governance structures for AI systems.

Governance refers to the policies, processes, and controls used to manage AI responsibly.

Governance Activities Include:

  • Defining acceptable AI usage
  • Reviewing high-risk systems
  • Monitoring model performance
  • Conducting audits
  • Managing compliance requirements
  • Responding to incidents

Strong governance improves accountability and reduces risk.

Human Oversight

Humans should remain involved in reviewing sensitive or high-impact AI decisions.

Examples

  • Doctors reviewing AI-assisted diagnoses
  • Recruiters reviewing hiring recommendations
  • Bank employees reviewing loan decisions

Human oversight helps:

  • Catch errors
  • Detect unfair outcomes
  • Prevent harmful actions
  • Improve trust

Auditability and Record Keeping

Organizations should maintain records about AI systems, including:

  • Training data sources
  • Model versions
  • System decisions
  • Performance metrics
  • Configuration changes
  • User activity logs

These records support:

  • Auditing
  • Troubleshooting
  • Compliance
  • Investigations

Auditability is an important accountability practice.

Monitoring AI Systems

AI systems should be continuously monitored after deployment.

Monitoring helps organizations identify:

  • Bias
  • Reliability issues
  • Security threats
  • Performance degradation
  • Unexpected behavior

Without monitoring, harmful issues may go unnoticed.

Incident Response

Organizations should prepare for situations where AI systems fail or behave improperly.

Example

If an AI chatbot begins generating harmful responses, the organization should have procedures for:

  • Disabling the system
  • Investigating the issue
  • Correcting the problem
  • Communicating with affected users

Accountability includes responding appropriately when problems occur.

Accountability in Generative AI

Generative AI introduces additional accountability challenges.

Organizations using generative AI should consider:

  • Content moderation
  • Human review
  • Usage policies
  • Monitoring outputs
  • Preventing misuse
  • Handling hallucinations and misinformation

Example

A company deploying an AI writing assistant remains responsible for ensuring harmful or misleading content is not distributed.

Legal and Ethical Responsibility

Organizations may face legal or regulatory consequences if AI systems:

  • Violate privacy laws
  • Discriminate unfairly
  • Cause financial harm
  • Create safety risks

Accountability helps ensure compliance with:

  • Industry regulations
  • Ethical standards
  • Internal policies

Shared Accountability

AI accountability is often shared across multiple groups, including:

  • Executives
  • Developers
  • Data scientists
  • Security teams
  • Compliance officers
  • Business stakeholders

Responsible AI requires collaboration across the organization.

Real-World Example

Scenario: AI Hiring System

A company uses AI to screen job applicants.

Accountability Risks

  • Biased hiring recommendations
  • Lack of human review
  • Poor documentation
  • Unclear responsibility for decisions

Accountability Practices

  • Human recruiter review
  • Audit logs
  • Regular fairness testing
  • Clear governance policies
  • Transparency with applicants
  • Monitoring system performance

Result

The organization maintains responsibility for hiring decisions rather than relying blindly on AI outputs.

This type of scenario aligns well with AI-901 exam questions.

Accountability and Transparency

Transparency and accountability are closely connected.

Transparency helps organizations:

  • Understand AI behavior
  • Investigate decisions
  • Explain outcomes
  • Support audits

Without transparency, accountability becomes more difficult.

Accountability and Human-in-the-Loop Systems

Human-in-the-loop systems require humans to participate in or approve AI-driven decisions.

Example

An AI fraud detection system flags suspicious transactions, but human analysts make the final decision to freeze accounts.

This approach improves accountability in high-risk scenarios.

Microsoft Responsible AI Principles

Microsoft identifies accountability as one of six Responsible AI principles:

  1. Fairness
  2. Reliability and safety
  3. Privacy and security
  4. Inclusiveness
  5. Transparency
  6. Accountability

For AI-901, understand that accountability focuses on ensuring humans and organizations remain responsible for AI systems and their outcomes.

Best Practices for Accountability in AI

Organizations commonly improve accountability through:

Governance Frameworks

Establish policies and procedures for responsible AI usage.

Human Oversight

Keep humans involved in sensitive decisions.

Monitoring and Auditing

Regularly review AI system behavior and maintain records.

Clear Roles and Responsibilities

Define who is responsible for:

  • Development
  • Deployment
  • Monitoring
  • Incident response

Transparency is one of Microsoft’s core Responsible AI principles and an important topic for the AI-901 certification exam. Transparency helps ensure that people understand when AI is being used, how AI systems make decisions, and what limitations or risks may exist.

Transparent AI systems help build trust, improve accountability, and support ethical decision-making.

What Is Transparency in AI?

Transparency in AI means that users and stakeholders should have appropriate visibility into:

  • When AI is being used
  • How AI systems make decisions
  • What data is being used
  • The capabilities and limitations of the AI system
  • The potential risks associated with the system

Transparency helps organizations avoid “black box” AI systems where decisions cannot be reasonably understood or explained.

Why Transparency Matters

AI systems increasingly influence important decisions in areas such as:

  • Healthcare
  • Banking
  • Hiring
  • Education
  • Insurance
  • Customer service
  • Government services

If users do not understand how AI systems operate, they may:

  • Lose trust in the system
  • Be unable to challenge incorrect decisions
  • Fail to identify bias or errors
  • Misuse the technology
  • Rely too heavily on inaccurate outputs

Transparent systems help users make informed decisions about how and when to use AI outputs.

Explainability in AI

One of the most important aspects of transparency is explainability.

Explainability refers to the ability to understand why an AI model made a specific decision or prediction.

Example

If an AI system denies a loan application, the organization should be able to explain the factors that influenced the decision.

Explainability is especially important in high-impact scenarios.

Black Box AI Systems

Some AI models, especially advanced deep learning systems, can be difficult to interpret.

These are sometimes called black box models because:

  • Their internal decision-making process is difficult to understand
  • Humans may not easily determine why a prediction was made

While highly complex models may offer strong performance, they can create transparency challenges.

Informing Users About AI Usage

Organizations should clearly communicate when users are interacting with AI systems.

Example

A chatbot should disclose that it is AI-powered rather than pretending to be a human agent.

Users should understand:

  • They are interacting with AI
  • AI-generated responses may contain errors
  • Human review may still be necessary

Transparency About Data Usage

Organizations should explain:

  • What data is collected
  • Why the data is collected
  • How the data is used
  • How long the data is retained
  • Who has access to the data

This supports both transparency and privacy goals.

Transparency in Generative AI

Generative AI systems create additional transparency considerations.

Users should understand that generated content may:

  • Be inaccurate
  • Contain hallucinations
  • Reflect bias
  • Be incomplete
  • Require verification

Example

An AI-generated summary should not automatically be assumed to be completely accurate without review.

Organizations should avoid presenting AI-generated information as guaranteed fact.

Model Documentation

Transparent AI systems often include documentation that explains:

  • Model purpose
  • Intended use cases
  • Training data sources
  • Known limitations
  • Performance characteristics
  • Risks and ethical considerations

Good documentation improves trust and accountability.

Human Interpretability

AI outputs should be understandable to the people using them whenever possible.

Example

A medical AI system may provide:

  • Confidence scores
  • Highlighted image regions
  • Explanations of risk factors

These explanations help doctors understand and validate the results.

Transparency and Trust

Transparency helps build trust because users are more likely to trust systems they understand.

Transparent AI systems help users:

  • Recognize limitations
  • Identify errors
  • Use AI responsibly
  • Make informed decisions

Lack of transparency can lead to skepticism, misuse, or overreliance on AI outputs.

Transparency vs. Complexity

There can be trade-offs between model complexity and explainability.

Example

A simple decision tree model may be easier to explain than a large neural network.

Organizations must balance:

  • Accuracy
  • Performance
  • Interpretability
  • Business requirements

In some high-risk scenarios, explainability may be more important than maximum predictive performance.

Real-World Example

Scenario: AI Loan Approval System

A bank uses AI to evaluate loan applications.

Transparency Requirements

  • Explain why applications are approved or denied
  • Inform users AI is assisting with decisions
  • Provide understandable explanations
  • Document model limitations
  • Allow human review of disputed decisions

Potential Risks Without Transparency

  • Customers may not understand denials
  • Hidden bias may go undetected
  • Regulators may raise compliance concerns
  • Trust in the system may decrease

Possible Solutions

  • Explainable AI tools
  • Human oversight
  • Model documentation
  • User communication
  • Decision summaries

This type of scenario aligns well with AI-901 exam questions.

Explainable AI (XAI)

Explainable AI (XAI) refers to techniques that help humans understand AI behavior.

XAI techniques may provide:

  • Feature importance
  • Confidence scores
  • Visual explanations
  • Decision summaries

These tools improve transparency and accountability.
