# Azure AI Services Overview

> Cloud-based AI services for building intelligent applications with vision, language, speech, and decision capabilities

# Azure AI Services

Azure AI Services are cloud-based artificial intelligence services that help developers build cognitive intelligence into applications without having direct AI or data science skills. These services provide pre-trained models and APIs across multiple AI domains.

## Available AI Services

Azure AI Services span four main categories: Vision, Language, Speech, and Decision APIs.

</CardGroup>

## Key Features

### Pre-trained Models

All services provide pre-trained models that work out of the box without requiring machine learning expertise.

### Custom Models

Many services support training custom models on your own data:

* Custom Vision for image recognition
* Custom Speech for speech recognition
* Custom Translator for domain-specific translation
* Document Intelligence custom models

### Enterprise Ready

* **Security**: Authenticate with Azure Active Directory and managed identities
* **Compliance**: Meet regulatory requirements with data residency and certifications
* **Scalability**: Auto-scale to handle varying workloads
* **Monitoring**: Track usage and performance with Azure Monitor

## Pricing

Azure AI Services use consumption-based pricing with different tiers:

* **Free Tier (F0)**: Limited transactions for evaluation and development
* **Standard Tier (S0)**: Pay-as-you-go pricing based on API calls
* **Commitment Tiers**: Discounted rates for predictable usage
