Third-Party Provider for Grok
This plugin provides Grok (by xAI) integration for the WP AI Client SDK. It enables WordPress sites to use Grok models for text generation and related AI capabilities.
Features:
- Text generation with Grok models
- Function calling support
- Vision input support (for compatible models)
- Automatic provider registration
Available models are dynamically discovered from the Grok API.
Requirements:
- PHP 7.4 or higher
- WP AI Client plugin must be installed and activated
- Grok API key from xAI
- Purchased API tokens from x.ai — a valid token balance is required for API requests to work
Usage
The provider automatically registers itself on the init hook. Once both plugins are active and your API key is configured, you can start generating text:
Basic Text Generation
$text = AI_Client::prompt( 'Explain quantum computing.' )->using_provider( 'grok' )->generate_text();
With System Instructions
$text = AI_Client::prompt( 'Summarize the history of WordPress.' )->using_provider( 'grok' )->using_system_instruction( 'Be concise and accurate.' )->using_temperature( 0.2 )->using_max_tokens( 500 )->generate_text();
Vision (Image Input)
$text = AI_Client::prompt( 'Describe this image.' )->using_provider( 'grok' )->with_file( 'https://example.com/photo.jpg', 'image/jpeg' )->generate_text();
Requires a Grok model with vision capabilities.
JSON Output
$json = AI_Client::prompt( 'Analyze this topic: WordPress plugins' )->using_provider( 'grok' )->as_json_response( $schema )->generate_text();
For full usage examples including chat history, function calling, and feature detection, see the README on GitHub.
External services
This plugin connects to the xAI Grok API to provide AI-powered text generation capabilities within WordPress. The xAI Grok API is a third-party service operated by xAI Corp.
What data is sent and when
- API key: Your xAI API key is sent with every request for authentication.
- Model listing: When the plugin checks provider availability or lists available models, it sends a request to the xAI API to retrieve the current list of Grok models.
- Text generation prompts: When your site uses the plugin to generate text, the prompt text (and any attached images or files, system instructions, and conversation history) is sent to the xAI API for processing.
All communication is sent to: https://api.x.ai/v1
Data is only sent when the plugin is actively used to generate text or when checking model availability. No data is sent passively or in the background.
