README

AI Provider for Mistral for the WordPress AI Client. Works as both a Composer package and a WordPress plugin.

This provider registers Mistral with the AI Client, exposing Mistral's models (Mistral Large, Medium, Small, the Ministral and Magistral families, and the vision-capable Pixtral models) for text generation through Mistral's OpenAI-compatible Chat Completions API.

Requirements

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

How it works

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

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

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

Supported capabilities

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

Mistral also serves embeddings, moderation, and OCR models; these are listed without text generation capability since they are not chat models.
