Introduction

As AI systems become more advanced, organizations increasingly use multiple AI agents working together rather than relying on a single monolithic model.

Multi-agent systems allow specialized agents to:

  • Collaborate
  • Delegate tasks
  • Share information
  • Coordinate workflows
  • Solve complex business problems

Azure AI Foundry provides orchestration capabilities that enable developers to design and implement coordinated multi-agent architectures.

For the AI-103: Develop AI Apps and Agents on Azure certification exam, understanding orchestrated multi-agent solutions is an important skill area.

This topic falls under these sections:
Implement generative AI and agentic solutions (30–35%)
--> Build agents by using Foundry
--> Build agents that integrate retrieval, function-calling, and conversation memory


Note that there are 10 practice questions (with answers and explanations) at the end of each section to help you solidify your knowledge of the material. Also, there are 2 practice tests with 60 questions each available from the hub's main page below the exam topics section.

Introduction

Modern AI agents are far more capable than traditional chatbots.

Today’s enterprise AI agents can:

  • Retrieve enterprise knowledge
  • Call APIs and tools
  • Maintain memory across conversations
  • Perform multistep workflows
  • Coordinate reasoning and actions

Azure AI Foundry provides the infrastructure and orchestration capabilities needed to build these advanced agentic systems.

For the AI-103: Develop AI Apps and Agents on Azure certification exam, understanding how to build agents that integrate:

  • Retrieval
  • Function-calling
  • Conversation memory

is extremely important.

These capabilities are foundational to enterprise generative AI systems.


What Is an AI Agent?

An AI agent is an AI-powered system capable of:

  • Understanding goals
  • Maintaining context
  • Using tools
  • Retrieving information
  • Performing actions
  • Adapting to new inputs

Agents extend beyond simple prompt-response interactions.


Core Components of Modern Agents

Modern agents commonly include:

  • Large language models (LLMs)
  • Retrieval systems
  • Tool integrations
  • Function-calling frameworks
  • Memory systems
  • Workflow orchestration
  • Safety controls

Retrieval in Agent Systems

Retrieval allows agents to:

  • Access external knowledge
  • Ground responses in enterprise data
  • Improve factual accuracy
  • Reduce hallucinations

Why Retrieval Matters

LLMs are trained on static datasets.

Without retrieval:

  • Models may lack current information
  • Enterprise-specific knowledge may be unavailable
  • Hallucinations become more likely

Retrieval-Augmented Generation (RAG)

Retrieval-Augmented Generation (RAG) combines:

  • Search and retrieval systems
  • LLM reasoning and generation

RAG allows agents to generate responses using retrieved content.


Typical RAG Workflow

A common RAG workflow includes:

  1. User submits a query
  2. Query is converted to embeddings
  3. Search retrieves relevant documents
  4. Documents are added to prompts
  5. LLM generates grounded responses

Knowledge Sources for Retrieval

Agents may retrieve data from:

  • Azure AI Search
  • Vector databases
  • SQL databases
  • Document repositories
  • SharePoint
  • Blob storage
  • Knowledge bases

Vector Search

Vector search enables semantic retrieval.

Instead of keyword matching only, vector search finds:

  • Meaning
  • Similarity
  • Contextual relationships

Embeddings

Embeddings are numerical vector representations of text or data.

Embeddings help systems:

  • Measure semantic similarity
  • Perform vector search
  • Improve retrieval relevance

Chunking Strategies

Documents are often split into smaller chunks before indexing.

Chunking improves:

  • Retrieval precision
  • Context quality
  • Token efficiency

Retrieval Pipelines

Retrieval pipelines commonly include:

  • Data ingestion
  • Chunking
  • Embedding generation
  • Indexing
  • Query retrieval
  • Reranking

Hybrid Search

Hybrid search combines:

  • Keyword search
  • Vector search

This improves search quality.


Grounding Responses

Grounding means generating responses using retrieved evidence.

Grounded systems are:

  • More accurate
  • More explainable
  • More reliable

Citation and Source Attribution

Agents may include:

  • Source links
  • Document citations
  • Retrieved evidence

This improves transparency.


Function-Calling in Agent Systems

Function-calling allows models to invoke:

  • APIs
  • Services
  • Workflows
  • Databases
  • External tools

Why Function-Calling Matters

LLMs alone cannot:

  • Access live systems
  • Execute actions
  • Retrieve dynamic business data

Function-calling bridges this gap.


Examples of Functions

Common functions include:

  • Get weather data
  • Retrieve customer records
  • Create support tickets
  • Query inventory systems
  • Send emails
  • Schedule meetings

Tool Schemas

Function-calling relies on structured tool schemas.

Schemas define:

  • Tool names
  • Parameters
  • Data types
  • Required fields
  • Expected outputs

Example Function Schema

Example:

Function: GetOrderStatus

Inputs:

  • OrderID
  • CustomerID

Outputs:

  • Shipping status
  • Estimated delivery date

Structured Tool Invocation

Structured tool invocation improves:

  • Reliability
  • Validation
  • Automation
  • Error handling

Function Selection Logic

Agents may decide:

  • Whether tools are needed
  • Which tools to invoke
  • When to call functions
  • How to sequence operations

Multi-Tool Workflows

Advanced agents may orchestrate:

  • Multiple tools
  • Sequential workflows
  • Conditional logic
  • Parallel execution

Example Multi-Tool Workflow

Example:

  1. Retrieve customer data
  2. Query billing system
  3. Generate summary
  4. Create support ticket
  5. Send notification

Tool Safety Controls

Organizations should control:

  • Which tools agents can access
  • Which users may trigger actions
  • Which workflows require approval

Human-in-the-Loop Approvals

High-risk operations may require:

  • Human review
  • Approval checkpoints
  • Escalation workflows

Conversation Memory

Conversation memory allows agents to:

  • Maintain context
  • Track interactions
  • Remember prior information
  • Continue workflows

Why Memory Matters

Without memory:

  • Conversations become disconnected
  • Users repeat information
  • Workflow continuity breaks

Types of Memory

Common memory types include:

  • Short-term memory
  • Long-term memory
  • Episodic memory
  • Semantic memory

Short-Term Memory

Short-term memory stores:

  • Recent prompts
  • Recent responses
  • Current task state

Long-Term Memory

Long-term memory stores:

  • User preferences
  • Historical interactions
  • Persistent context

Stateful vs Stateless Agents

Stateless Agents

Do not retain memory between sessions.

Benefits:

  • Simpler architecture
  • Lower storage requirements

Stateful Agents

Maintain context and conversation history.

Benefits:

  • Better user experiences
  • Improved multistep reasoning

Context Window Limitations

LLMs have limited context windows.

  1. Analyze request
  2. Retrieve information
  3. Call tools
  4. Evaluate outputs
  5. Continue reasoning
  6. Generate response

Workflow State Management

Agents may track:

  • Active tasks
