AI Provider for exo

This plugin registers exo as an AI provider in WordPress 7's AI Client SDK and Connectors page. exo connects all your devices into an AI cluster, enabling you to run frontier models locally. It exposes an OpenAI-compatible API that this plugin connects to. Features:

• Registers exo as a WordPress AI provider
• OpenAI-compatible text generation via exo's chat completions API
• Auto-detect active models from your running exo cluster
• Capability detection — displays model capabilities (Text, Code, Thinking, Vision) as badges
• "Connect & Detect" / "Save & Re-detect" connector flow
• Optional API key authentication with secure storage
• Configurable endpoint URL (default: http://localhost:52415)
• Settings integrated into WordPress 7's Connectors page

Choosing a Model: exo exposes every model in its catalog, but only models actively loaded on your cluster will respond. Use "Connect & Detect" on the Connectors page to discover which models are running. Recommended — Instruct models produce clean, usable output for WordPress AI features (title generation, content suggestions, etc.):

• Llama-3.2-3B-Instruct-8bit — ~3 GB, fast, great for short tasks
• Meta-Llama-3.1-8B-Instruct-4bit — ~4 GB, good balance of speed and quality
• Llama-3.3-70B-Instruct-4bit — ~35 GB, best quality, needs a larger cluster

Avoid — Reasoning/thinking models (Qwen3.5, DeepSeek, GLM, Nemotron-Nano) spend most tokens on internal chain-of-thought, producing slow responses with minimal visible output. To load a model: exo run mlx-community/Llama-3.2-3B-Instruct-8bit Requirements:

• WordPress 7.0 or later
• PHP 8.3 or later
• A running exo cluster (see exo documentation)

1.0.1

• Added GitHub Actions workflow for deployment to WordPress.org.

1.0.0

• Prefix all declarations, globals, and stored data for WordPress.org compliance.
• Namespace changed to Aiprfoex.
• Constants, options, REST namespace, script handles, and provider slug all use the aiprfoex prefix.
• Environment variable names changed: AIPRFOEX_ENDPOINT, AIPRFOEX_API_KEY, AIPRFOEX_MODEL.
• Add sanitize_callback to register_setting() for capabilities option.
• Remove load_plugin_textdomain() — WordPress.org handles translations automatically.

0.3.0

• Fix: resolve "RequestAuthenticationInterface instance not set" error in AI plugin title generation.
• Fix: emulate multi-candidate responses — exo ignores OpenAI n parameter, now issues N sequential requests.
• Implement createRequest() abstract method required by SDK.
• Always register authentication even with empty API key (SDK requires an instance).
• Whitelist localhost and non-standard ports for wp_safe_remote_request().
• Prepend exo models to wpai_preferred_text_models filter for correct provider selection.
• Increase request timeout to 300s for local inference.
• Default max_tokens to 1024 to prevent unbounded reasoning in thinking models.
• Add model selection guidance to documentation.

0.2.0

• Add sentinel connector for WordPress AI plugin compatibility.
• AI plugin now recognizes exo as a valid, configured provider.
• Filter to hide internal sentinel connector from Connectors settings page.
• Custom exo wordmark logo (40×40 square) for the Connectors page.
• Fix: AI plugin showed "requires a valid AI Connector" despite exo being configured.

0.1.0

• Initial release.
• Register exo as a WordPress AI provider via the AI Client SDK.
• OpenAI-compatible text generation through exo's chat completions API.
• Auto-detect active models from the exo cluster (REST endpoint: POST /exo/v1/detect).
• Capability detection — captures and displays model capabilities (Text, Code, Thinking, Vision) as badges.
• Connector settings UI with "Connect & Detect" / "Save & Re-detect" flow.
• Detected active models displayed in a read-only panel with Refresh support.
• Custom exo logo icon for the Connectors page.
• Optional API key authentication with secure storage and masking.
• Configurable endpoint URL (default: http://localhost:52415).
• Environment variable and wp-config.php constant support (EXO_ENDPOINT, EXO_API_KEY, EXO_MODEL).
• Full i18n support with Norwegian Bokmål (nb_NO) translation.
