AI Provider for OpenCode Zen

An independent, third-party OpenCode Zen provider for the PHP AI Client SDK. Works as both a Composer package and a WordPress plugin. Not affiliated with, endorsed by, or sponsored by OpenCode Zen.

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 mralaminahamed/ai-provider-for-opencode-zen

As a WordPress Plugin

1. Download the plugin files
2. Upload to /wp-content/plugins/alamin-ai-provider-for-opencode-zen/
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 OpenCode Zen API key (or use the OPENCODE_ZEN_API_KEY environment variable)
putenv('OPENCODE_ZEN_API_KEY=your-api-key');

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

As a Standalone Package

use WordPress\AiClient\AiClient;
use AlAminAhamed\OpenCodeZenAiProvider\Provider\OpenCodeZenProvider;

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

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

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

echo $result->toText();

Supported Models

Available models are dynamically discovered from the OpenCode Zen API. This includes GPT and Claude models for text generation. The provider falls back to a default model list when the API is unavailable.

Configuration

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

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