Modern AI systems are increasingly capable of understanding not only text and speech, but also visual information such as images and videos. Multimodal AI models combine multiple forms of input to generate intelligent responses and insights.

For the AI-901 certification exam, candidates should understand the foundational concepts behind interpreting visual input in prompts by using deployed multimodal models through Microsoft Azure AI Foundry and related Azure AI services.

This topic falls under the “Implement AI solutions with computer vision and image-generation capabilities by using Foundry” section of the AI-901 exam objectives.

What Is a Multimodal Model?

A multimodal model is an AI model capable of processing multiple types of input and output.

These modalities may include:

  • Text
  • Images
  • Speech/audio
  • Video

Multimodal models can combine information across different input types to generate responses.

What Is Visual Input?

Visual input refers to image or video data provided to an AI system.

Examples include:

  • Photographs
  • Screenshots
  • Documents
  • Charts
  • Diagrams
  • Videos

Example Visual Prompt

A user uploads a photo and asks:

“What objects are visible in this image?”

The AI analyzes the visual content and generates a response.

Computer Vision

Computer vision is the field of AI focused on enabling systems to interpret and understand visual information.

Computer vision tasks include:

  • Image classification
  • Object detection
  • Facial analysis
  • Optical character recognition (OCR)
  • Image captioning

Azure AI Vision

Azure AI Vision provides computer vision capabilities in Azure.

Features include:

  • Image analysis
  • OCR
  • Object detection
  • Image captioning
  • Face-related analysis

Azure AI Foundry

Azure AI Foundry provides tools for building and managing multimodal AI applications.

Developers can:

  • Deploy AI models
  • Test prompts
  • Analyze images
  • Build AI-powered apps

Deployed Models

A deployed model is an AI model made available for real-time use through a cloud endpoint.

Applications communicate with deployed models using APIs.

Visual Prompt Workflow

A common workflow includes:

  1. User uploads image
  2. Application sends image to multimodal model
  3. Model analyzes visual content
  4. Model generates response
  5. Application displays results

Example Workflow

User Uploads Image

A photo of a dog playing in a park

User Prompt

“Describe this image.”

AI Response

“A brown dog is running through a grassy park.”

Image Classification

Image classification identifies the primary category of an image.

Example

Image

Picture of a cat

Classification

“Cat”

Object Detection

Object detection identifies and locates multiple objects within an image.

Example

Image

Street scene

Detected Objects

  • Car
  • Bicycle
  • Traffic light
  • Pedestrian

Optical Character Recognition (OCR)

OCR extracts text from images or scanned documents.

Example

Image

Photo of a receipt

Extracted Text

  • Store name
  • Total amount
  • Date

Image Captioning

Image captioning generates natural-language descriptions of images.

Example

Image

A child flying a kite

Caption

“A child flying a colorful kite in a field.”

Visual Question Answering

Some multimodal models can answer questions about images.

Example

Prompt

“How many people are in the image?”

The model analyzes the image and generates an answer.

Combining Text and Images

Multimodal systems often combine:

  • Text prompts
  • Visual input

This improves contextual understanding.

Example

Image

A restaurant menu

Prompt

“Which item appears to be vegetarian?”

The AI analyzes both the image and the prompt together.

APIs and Endpoints

Applications communicate with deployed multimodal models through:

  • APIs
  • Endpoints

These allow images and prompts to be submitted programmatically.

Authentication

Applications must securely authenticate before accessing Azure AI services.

Common methods include:

  • API keys
  • Azure credentials
  • Managed identities

User Interface Components

A lightweight visual AI application may include:

  • Image upload area
  • Prompt input box
  • Results display
  • Image preview

Real-Time Processing

Many multimodal applications support near real-time image analysis.

This enables interactive user experiences.

Transparency

Users should understand:

  • AI is analyzing images
  • AI-generated descriptions may contain errors
  • Images may be stored or processed in the cloud

Hallucinations

Multimodal AI systems may generate inaccurate visual descriptions.

These incorrect outputs are called hallucinations.

Applications should not assume all AI-generated outputs are accurate.

Error Handling

Applications should handle:

  • Unsupported image formats
  • Low-quality images
  • Network failures
  • Authentication errors
  • Rate limits

Image Quality Challenges

Poor image quality can reduce accuracy.

Examples include:

  • Blurry images
  • Poor lighting
  • Occluded objects
  • Low resolution

Advantages of Visual AI Applications

High-Level Workflow

A simplified workflow includes:

  1. Upload image
  2. Send image and prompt to model
  3. Analyze visual content
  4. Generate response
  5. Display results

Example High-Level Pseudocode

image = upload_image()
prompt = get_prompt()
response = analyze_image(image, prompt)
display_response(response)

For AI-901, understanding the workflow is more important than memorizing exact syntax.

This topic falls under the “Implement AI solutions for text and speech by using Foundry” section of the AI-901 exam objectives.

What Is a Multimodal Model?

A multimodal model is an AI model capable of processing multiple forms of input and output.

Examples of modalities include:

  • Text

A multimodal model can combine information from multiple sources to generate responses.

Examples of Multimodal AI Systems

Common examples include:

  • Voice assistants
  • AI copilots
  • Speech-enabled chatbots
  • Image-and-text AI assistants
  • Interactive educational tools

What Is a Spoken Prompt?

A spoken prompt is a voice-based user input provided through audio.

Instead of typing a question, the user speaks it aloud.

Example Spoken Prompt

“What is machine learning?”

The AI system converts the speech into text for processing.

Speech Recognition

Speech recognition converts spoken language into text.

This process is often called:

  • Speech-to-text (STT)
  • Automatic speech recognition (ASR)

Example Speech Recognition Workflow

Spoken Audio

“What time is the meeting tomorrow?”

Converted Text

“What time is the meeting tomorrow?”

The text is then processed by the AI model.

Speech Synthesis

Speech synthesis converts text into spoken audio.

This process is often called:

  • Text-to-speech (TTS)

Example

AI Response Text

“The meeting starts at 10 AM.”

Spoken Output

The AI system reads the response aloud.

Azure AI Speech

Azure AI Speech provides speech recognition and speech synthesis capabilities.

Features include:
