Identify Features and Uses for Language Modeling (AI-900 Exam Prep)

Overview

Language modeling is a core concept in Natural Language Processing (NLP) that focuses on enabling machines to understand, generate, and predict human language. In the context of the AI-900 exam, language modeling is not about building models from scratch, but about recognizing what language models do, what problems they solve, and how Azure provides access to them.

Language models power many modern AI experiences, including chatbots, text generation, summarization, translation, and question answering.


What Is a Language Model?

A language model is a type of AI model that learns patterns in language so it can:

  • Predict the next word or token in a sequence
  • Understand context and meaning
  • Generate coherent and contextually relevant text

At a fundamental level, language models calculate the probability of word sequences, which allows them to both interpret and generate language.


Key Features of Language Modeling

1. Text Prediction and Generation

Language models can:

  • Predict the next word in a sentence
  • Generate full sentences, paragraphs, or documents
  • Produce human-like responses in conversations

Example:

“The weather today is very…” → sunny


2. Context Awareness

Modern language models (especially transformer-based models) consider context, not just individual words.

This allows them to:

  • Understand sentence meaning
  • Maintain coherence across multiple sentences
  • Respond appropriately based on prior text

3. Natural Language Understanding and Generation

Language models support both:

  • Understanding text (reading and interpreting meaning)
  • Generating text (writing responses, summaries, or explanations)

This dual capability is central to many NLP workloads.


4. Pretrained Models

In Azure, language modeling typically relies on pretrained models, meaning:

  • No custom training is required
  • Models are already trained on large text datasets
  • Users can immediately apply them to common NLP tasks

This aligns with the AI-900 focus on consuming AI services, not building models.


Common Uses of Language Modeling

1. Chatbots and Virtual Assistants

Language models enable conversational AI by:

  • Understanding user input
  • Generating natural responses
  • Maintaining conversation context

Azure Example:
Chatbots built using Azure OpenAI Service or language-based Azure AI services.


2. Text Completion and Content Generation

Language models can:

  • Auto-complete sentences
  • Generate emails, reports, or documentation
  • Assist with creative writing or code comments

3. Question Answering

Language models can:

  • Interpret natural language questions
  • Generate relevant answers based on context or provided data

This is commonly used in:

  • Help desks
  • Knowledge bases
  • Internal support tools

4. Text Summarization

Language models can:

  • Condense long documents
  • Extract key points
  • Provide concise summaries

This helps users quickly understand large volumes of text.


5. Language Translation and Adaptation

While translation is often a separate NLP workload, language models:

  • Understand sentence structure
  • Preserve meaning across languages
  • Adapt phrasing naturally

Language Modeling in Azure

In Azure, language modeling capabilities are available through services such as:

Azure OpenAI Service

  • Provides access to powerful large language models
  • Supports text generation, chat, summarization, and reasoning tasks
  • Uses pretrained transformer-based models

Azure AI Language

  • Focuses on structured NLP tasks
  • Complements language modeling with features like sentiment analysis and entity recognition

For AI-900, it’s important to recognize what language models enable, not the underlying implementation details.


Language Modeling vs Other NLP Tasks (Exam Tip)

NLP TaskFocus
Sentiment analysisEmotional tone
Entity recognitionIdentifying names, places, organizations
Key phrase extractionImportant terms
Language modelingUnderstanding and generating language

If the question involves predicting, generating, or responding with text, language modeling is likely the correct concept.


Why Language Modeling Matters for AI-900

Microsoft includes language modeling in AI-900 to ensure candidates understand:

  • How modern AI systems interact with human language
  • Why conversational AI is possible
  • How Azure provides ready-to-use NLP capabilities

Identify Features of Generative AI Models (AI-900 Exam Prep)

Introduction

Generative AI models are a class of artificial intelligence systems designed to create new content rather than simply analyze or classify existing data. In the AI-900 exam, Microsoft focuses on conceptual understanding, not implementation details. You are expected to recognize what generative AI models do, how they behave, and what makes them different from traditional machine learning models.

Generative AI underpins many modern Azure AI solutions, including Azure OpenAI Service, and plays a central role in text, image, code, and audio generation workloads.


What Is a Generative AI Model?

A generative AI model learns patterns, structure, and relationships from large datasets and uses that knowledge to generate new, original outputs that resemble the data it was trained on.

Unlike predictive models (which output labels or numeric values), generative models produce:

  • Text
  • Images
  • Code
  • Audio
  • Synthetic data

Key Features of Generative AI Models (Exam Focus)

1. Content Generation

Generative AI models can create new content rather than selecting from predefined responses.

Examples:

  • Writing emails, stories, or summaries
  • Generating images from text descriptions
  • Producing computer code
  • Creating conversational responses

AI-900 cue: If the scenario involves creating something new, it likely involves generative AI.


2. Large Pretrained Models

Generative AI models are typically pretrained on massive datasets containing text, images, or other media.

Key characteristics:

  • Trained on diverse, large-scale data
  • Capture language structure, context, and semantics
  • Can generalize to many tasks without retraining

Examples:

  • Large language models (LLMs)
  • Multimodal foundation models

3. Prompt-Based Interaction

Generative AI models are commonly controlled using prompts, which are natural language instructions or inputs.

Prompts can:

  • Ask questions
  • Provide instructions
  • Set constraints or styles
  • Include examples (few-shot prompting)

Exam tip: Prompts guide how the model responds but do not retrain the model.


4. Probabilistic Output (Non-Deterministic)

Generative AI models produce probabilistic responses, meaning:

  • The same prompt can produce different outputs
  • Responses are not fixed or guaranteed
  • Outputs are generated based on likelihood, not rules

This enables creativity but also requires careful validation.


5. Context Awareness

Generative AI models can use context provided in a conversation or prompt to influence responses.

Examples:

  • Remembering earlier parts of a conversation
  • Adjusting tone or topic based on prior input
  • Generating coherent multi-turn dialogue

This is especially relevant for chat-based AI systems.


6. General-Purpose Capability

Generative AI models are often multi-task by design.

A single model can:

  • Answer questions
  • Summarize text
  • Translate languages
  • Generate explanations
  • Write code

This contrasts with traditional ML models, which are typically task-specific.


7. Fine-Tuning and Customization

While generative AI models are pretrained, they can be:

  • Fine-tuned with domain-specific data
  • Prompt-engineered for specific use cases
  • Configured with system instructions

For AI-900, it’s important to know customization is possible, not how to implement it.


8. Human-Like Outputs

Generative AI models are designed to produce outputs that appear:

  • Natural
  • Fluent
  • Contextually relevant
  • Similar to human-generated content

This is especially true for text and conversational AI.


9. Support for Multimodal Data

Some generative AI models can work across multiple data types, such as:

  • Text → Image
  • Image → Text
  • Text → Code

AI-900 expects recognition of this capability, not technical depth.


10. Need for Responsible AI Controls

Generative AI models require safeguards due to risks such as:

  • Hallucinations (incorrect but confident outputs)
  • Bias
  • Harmful or inappropriate content

Microsoft emphasizes:

  • Content filtering
  • Responsible AI principles
  • Human oversight

Generative AI vs Traditional Machine Learning (High-Yield Comparison)

AspectTraditional MLGenerative AI
Primary goalPredict or classifyCreate new content
Output typeLabels or numbersText, images, code, audio
Task scopeNarrow, specificBroad, general-purpose
Interaction styleStructured inputsNatural language prompts
CreativityNoneHigh

Azure Context (What AI-900 Expects You to Recognize)

Generative AI workloads on Azure are commonly delivered through:

  • Azure OpenAI Service
  • Integrated Azure AI tooling
  • Secure, enterprise-ready AI deployments

You are not expected to know APIs or pricing — only capabilities and use cases.


Common Exam Triggers to Watch For 👀

If a question mentions:

  • Writing text
  • Creating images
  • Generating code
  • Conversational responses
  • Prompt-based interaction

➡️ Think: Generative AI model


Summary
