README

AI Provider for xAI (Grok) for the WordPress AI Client. Works as both a Composer package and a WordPress plugin.

This provider registers xAI with the AI Client, exposing the Grok model family for text generation through xAI's OpenAI-compatible Chat Completions API.

Requirements

PHP 7.4+
WordPress 6.9+ (when used as a plugin)
The wordpress/php-ai-client SDK
An xAI API key from the xAI console

How it works

xAI exposes an OpenAI-compatible API, so this provider is intentionally thin:

Class	Responsibility
`Provider\XaiProvider`	Registers the provider, base URL (`https://api.x.ai/v1`), API-key auth, and metadata.
`Metadata\XaiModelMetadataDirectory`	Lists models from `GET /v1/models` and maps capabilities/options.
`Models\XaiTextGenerationModel`	Sends `POST /v1/chat/completions` via the shared OpenAI-compatible base class.

Because Grok speaks the Chat Completions format, XaiTextGenerationModel extends AbstractOpenAiCompatibleTextGenerationModel from the SDK and only overrides request construction.

Supported capabilities

Text generation (chat) with the Grok model family
Multimodal (image) input for vision-capable models (e.g. the Grok 4 family)
Function calling and JSON / structured output
