AI Provider for OpenAI

An AI Provider for OpenAI for the PHP AI Client SDK. Works as both a Composer package and a WordPress plugin.

Requirements

• PHP 7.4 or higher
• When using with WordPress, requires WordPress 7.0 or higher
  • If using an older WordPress release, the wordpress/php-ai-client package must be installed

Installation

As a Composer Package

composer require wordpress/ai-provider-for-openai

As a WordPress Plugin

1. Download the plugin files
2. Upload to /wp-content/plugins/ai-provider-for-openai/
3. Ensure the PHP AI Client plugin is installed and activated
4. Activate the plugin through the WordPress admin

Usage

With WordPress

The provider automatically registers itself with the PHP AI Client on the init hook. Simply ensure both plugins are active and configure your API key:

// Set your OpenAI API key (or use the OPENAI_API_KEY environment variable)
putenv('OPENAI_API_KEY=your-api-key');

// Use the provider
$result = AiClient::prompt('Hello, world!')
    ->usingProvider('openai')
    ->generateTextResult();

As a Standalone Package

use WordPress\AiClient\AiClient;
use WordPress\OpenAiAiProvider\Provider\OpenAiProvider;

// Register the provider
$registry = AiClient::defaultRegistry();
$registry->registerProvider(OpenAiProvider::class);

// Set your API key
putenv('OPENAI_API_KEY=your-api-key');

// Generate text
$result = AiClient::prompt('Explain quantum computing')
    ->usingProvider('openai')
    ->generateTextResult();

echo $result->toText();

Supported Models

Available models are dynamically discovered from the OpenAI API. This includes GPT models for text generation, DALL-E and GPT Image models for image generation, and TTS models for text-to-speech. See the OpenAI documentation for the full list of available models.

Configuration

The provider uses the OPENAI_API_KEY environment variable for authentication. You can set this in your environment or via PHP:

putenv('OPENAI_API_KEY=your-api-key');
