AI Provider for ZenMUX

Description

This plugin connects WordPress AI features to ZenMUX, an OpenAI-compatible AI aggregation
service. It registers a ZenMUX provider with the WordPress AI Client and supports:

• Text generation and chat history, including tools and structured JSON output.
• Vision input for models that accept images.
• Image generation for image models.
• Image editing (refinement) when the prompt carries one or more reference images.

The model catalog is read from ZenMUX’s GET /models endpoint, so models ZenMUX adds or
removes appear automatically.

Setup

1. Activate the plugin.
2. Open Settings > Connectors and save your ZenMUX API key. You can create one at
   https://zenmux.ai/platform/pay-as-you-go.
3. Optional: configure the provider with environment variables or PHP constants:

• ZENMUX_BASE_URL – API base URL. Default https://zenmux.ai/api/v1.
• ZENMUX_DEFAULT_MODEL – preferred text and vision model. Default openai/gpt-5.
• ZENMUX_IMAGE_MODEL – preferred image model. Default openai/gpt-image-2.
• ZENMUX_REQUEST_TIMEOUT – request timeout in seconds. Default 120.
• ZENMUX_CONNECT_TIMEOUT – connection timeout in seconds. Default 10.
• ZENMUX_API_KEY – the API key, as an alternative to the Connectors screen.

External Services

This plugin connects to ZenMUX, a service provided by NexaMind Singapore Pte. Ltd. The
connection is required to generate AI output. The plugin sends your prompts to ZenMUX through
its API and displays the generated result in WordPress. No other external service is used.

Data is sent only when an AI request is made while a ZenMUX model is selected or preferred,
and only after the site administrator has configured a ZenMUX API key. Each request sends:

• The prompt, conversation messages, and any system instruction.
• Attached image data, or a reference to it, when the request contains an image.
• Tool and function declarations, and the JSON schema used for structured output, when the request uses them.
• The configured model ID and the generation settings for the request, such as token limits, temperature, stop sequences, image size, and quality.
• The ZenMUX API key stored in Settings > Connectors, sent as the Authorization header.

Requests go to the ZenMUX API base URL, https://zenmux.ai/api/v1 by default. The plugin
contacts these endpoints:

• GET /models – lists the available models.
• POST /chat/completions – text and vision generation.
• POST /images/generations – image generation.
• POST /images/edits – image editing.

Nothing is sent to the plugin author or to any other service.
