• Image generation using DALL-E 2 and DALL-E 3 deployments
• Embedding generation using text-embedding-ada-002, text-embedding-3-small/large deployments
• Text-to-speech using tts-1 and tts-1-hd deployments
• Integrated into the Connectors settings page (Settings → Connectors) — configure API key, endpoint, deployment, and capabilities in one place
• Multimodal input support (text, image, audio, document combinations)
• Environment variable support for credentials

Requirements

• WordPress 7.0 or higher
• PHP 7.4 or higher
• Azure OpenAI resource with deployed models

Installation

1. Download ai-provider-for-azure-openai.zip
2. Upload via Plugins → Add New → Upload Plugin
3. Activate the plugin through the WordPress admin

Configuration

Connectors Page

1. Go to Settings → Connectors
2. Find Azure OpenAI and click Set Up
3. Enter your API Key (from Azure Portal → Your OpenAI Resource → Keys and Endpoint)
4. Enter your Endpoint URL, API Version, Deployment ID, and Capabilities
5. Click Save Settings

All settings are stored as individual options and exposed via the REST Settings API.

Via Environment Variables

Set the following environment variables:

export AZURE_OPENAI_API_KEY="your-api-key"
export AZURE_OPENAI_ENDPOINT="https://your-resource.openai.azure.com"
export AZURE_OPENAI_API_VERSION="2024-02-15-preview"  # Optional
export AZURE_OPENAI_DEPLOYMENT_ID="gpt-4o"             # Optional
export AZURE_OPENAI_CAPABILITIES="text_generation,chat_history"  # Optional, comma-separated

Available capabilities: text_generation, image_generation, chat_history, embedding_generation, text_to_speech_conversion

Environment variables are used as fallbacks when settings are not saved in the database.

Usage

Once configured, the Azure OpenAI provider is automatically registered with the WordPress AI Client and can be used like any other provider:

use WordPress\AiClient\AiClient;

// Get an Azure OpenAI model
$registry = AiClient::defaultRegistry();
$model = $registry->getProviderModel( 'azure_openai', 'gpt-4o' );

// Generate text
$result = $model->generateText( [
    [ 'role' => 'user', 'content' => 'Hello, how are you?' ]
] );

echo $result->getText();

API Differences from OpenAI

Azure OpenAI uses a different URL structure:

{endpoint}/openai/deployments/{deployment}/chat/completions?api-version={version}

And uses the api-key header instead of Authorization: Bearer:

api-key: your-api-key

The plugin handles these differences automatically.
