AI Provider for Azure OpenAI

Azure OpenAI provider for the PHP AI Client SDK. Works as both a Composer package with the php-ai-client package and as a WordPress plugin with the wp-ai-client plugin.

Azure OpenAI is Microsoft's cloud service that hosts OpenAI models — including GPT-4o, DALL-E, GPT Image, and TTS — through Azure infrastructure with enterprise security and compliance. This provider connects to your Azure OpenAI resource using your own endpoint URL, API key, and configured deployments.

Requirements

• PHP 7.4+
• php-ai-client ^0.4 or wp-ai-client ^0.2
• An Azure subscription with an Azure OpenAI resource and at least one deployment

Installation

As a WordPress Plugin

1. Install and activate the wp-ai-client plugin.
2. Place this plugin in your wp-content/plugins/ directory.
3. Activate "AI Provider for Azure OpenAI" from the Plugins screen.

As a Composer Package

composer require fueled/ai-provider-for-azure-openai

Configuration

1. Endpoint URL

Go to Settings > Azure OpenAI Settings and enter the base URL of your Azure OpenAI resource. You can find this in the Azure Portal under your resource → Keys and Endpoint. It looks like:

https://myresource.openai.azure.com

Do not include /openai/v1 — it is appended automatically. You can also set the AZURE_OPENAI_ENDPOINT environment variable to override this setting, which is useful for local development or staging environments.

2. API Key

Enter your Azure OpenAI API key on the Settings > AI Credentials screen under the azure_openai provider. You can find your API key in the Azure Portal under your resource → Keys and Endpoint.

3. Deployments

On the Settings > Azure OpenAI Settings screen, add each of your Azure OpenAI deployments by clicking Add Deployment. For each deployment, enter:

• Deployment Name — the name you gave the deployment in Azure AI Foundry (e.g. my-gpt4o).
• Model Type — the capability set for this deployment:

Type	Use for
Chat (Text Generation)	Text-only GPT deployments (GPT-3.5, GPT-4, o1, o3, o4-mini, etc.)
Chat + Vision (Multimodal)	GPT deployments that accept images and documents (GPT-4o, GPT-4o mini, etc.)
Image Generation (DALL-E)	DALL-E 2 and DALL-E 3 deployments
Image Generation (GPT Image)	GPT Image 1 deployments
Text-to-Speech	TTS-1 and TTS-1-HD deployments

Usage

With WordPress (wp-ai-client)

use WordPress\AI_Client\Prompt_Builder;

$result = Prompt_Builder::create()
    ->using_provider( 'azure_openai' )
    ->set_system_instruction( 'You are a helpful assistant.' )
    ->add_text_message( 'Hello, how are you?' )
    ->generate_text();

Standalone PHP (php-ai-client)

use Fueled\AiProviderForAzureOpenAI\Metadata\AzureOpenAIModelMetadataDirectory;
use Fueled\AiProviderForAzureOpenAI\Provider\AzureOpenAIProvider;
use WordPress\AiClient\AiClient;
use WordPress\AiClient\Providers\Http\DTO\ApiKeyRequestAuthentication;

require_once 'vendor/autoload.php';

putenv( 'AZURE_OPENAI_ENDPOINT=https://myresource.openai.azure.com' );

AzureOpenAIModelMetadataDirectory::setDeployments( array(
    array( 'name' => 'my-gpt4o', 'type' => 'chat_multimodal' ),
) );

$registry = AiClient::defaultRegistry();
$registry->registerProvider( AzureOpenAIProvider::class );
$registry->setProviderRequestAuthentication( 'azure_openai', new ApiKeyRequestAuthentication( 'your-api-key' ) );

$result = AiClient::prompt( 'Hello!' )
    ->usingProvider( 'azure_openai' )
    ->usingModel( 'my-gpt4o' )
    ->generateText();
