<li>Chat History — Maintain conversation context across multiple interactions.</li>
<li>Dynamic Model Discovery — Available models are fetched directly from the OpenCode API, so your plugin stays compatible with new releases automatically.</li>
<li>Automatic Provider Registration — Registers itself with the PHP AI Client on WordPress init; no manual wiring needed.</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>PHP 7.4 or higher</li>

<li>OpenCode API key</li>
</ul>
<h3>External Services</h3>

Nominal AI Provider for OpenCode

Nominal AI Provider for OpenCode for the PHP AI Client SDK. Use your OpenCode Go or Zen AI models within WordPress.

This plugin provides <a href="https://opencode.ai" rel="nofollow ugc">OpenCode Zen</a> integration for the WordPress AI Client. It enables WordPress sites to use OpenCode Zen’s AI gateway — accessing GPT, Claude, Gemini, Qwen, MiniMax, Kimi, and more through a single OpenAI-compatible API.
This plugin is an independent, third-party integration and is not affiliated with, endorsed by, or sponsored by OpenCode Zen.
<h4>Why OpenCode Zen?</h4>
OpenCode Zen is an AI model aggregator — one API key gives you access to 40+ frontier models from OpenAI, Anthropic, Google, and others. Instead of managing separate API keys and billing accounts for each AI provider, you connect once to OpenCode Zen and switch between models freely.
This makes it ideal for WordPress sites that want to experiment with different AI models, compare output quality, or use specialised models (e.g. a coding model for code-related tasks and a creative model for content).
<h4>Features</h4>
<ul>
<li>40+ models from one API key — GPT 5.x, Claude 4.x, Gemini 3.x, Qwen, MiniMax, Kimi, Grok, DeepSeek, and more</li>
<li>Automatic model discovery — live model list fetched from the OpenCode Zen API and cached hourly; falls back to a hardcoded list when offline</li>
<li>Full parameter control — temperature, max tokens, top P, presence penalty, frequency penalty, stop sequences, system instruction, and function declarations</li>
<li>Settings page — configure default model and generation parameters without touching code</li>
<li>API key via Connectors — enter your key once in Settings > Connectors; all AI-enabled plugins share it automatically</li>
<li>Environment variable support — <code>OPENCODE_ZEN_API_KEY</code> for server-level configuration, bypassing the database entirely</li>
<li>OpenAI-compatible API — built on the same protocol as OpenAI, so any model that works with the OpenAI provider works here</li>
<li>No vendor lock-in — switch between GPT, Claude, and Gemini without changing plugin or configuration</li>
</ul>
<h4>What Can You Do With AI in WordPress?</h4>
Once this provider is configured, any WordPress plugin or theme that integrates with the WordPress AI Client can use it:
<ul>
<li>Block editor (Gutenberg) — AI writing assistance, rephrasing, summarising, and expanding content</li>
<li>WooCommerce — AI-generated product descriptions, SEO meta titles, and customer review summaries</li>
<li>SEO plugins — generate meta descriptions, focus keyphrases, and Open Graph content</li>
<li>Customer support — power AI chatbots and FAQ auto-responses</li>
<li>Translation and localisation — translate and adapt content for different markets</li>
<li>Code generation — use a coding-specialised model (GPT 5.3 Codex, Grok Build) directly in the editor</li>
<li>Image alt text — generate accessible alt attributes for media library images</li>
</ul>
<h4>Supported Models</h4>
When an API key is configured, the live model list is fetched from the OpenCode Zen API. The built-in fallback list includes:
GPT models 
GPT 5.5, GPT 5.5 Pro, GPT 5.4, GPT 5.4 Pro, GPT 5.4 Mini, GPT 5.4 Nano, GPT 5.3 Codex, GPT 5.3 Codex Spark, GPT 5.2, GPT 5.2 Codex, GPT 5.1, GPT 5.1 Codex, GPT 5.1 Codex Max, GPT 5.1 Codex Mini, GPT 5, GPT 5 Codex, GPT 5 Nano
Claude models 
Claude Fable 5, Claude Opus 4.8, Claude Opus 4.7, Claude Opus 4.6, Claude Opus 4.5, Claude Opus 4.1, Claude Sonnet 4.6, Claude Sonnet 4.5, Claude Sonnet 4, Claude Haiku 4.5, Claude 3.5 Haiku
Gemini models 
Gemini 3.5 Flash, Gemini 3.1 Pro, Gemini 3 Flash
Other models 
Qwen 3.6 Plus, Qwen 3.5 Plus, MiniMax M2.7, MiniMax M2.5, GLM 5.1, Kimi K2.6, Kimi K2.5, Grok Build 0.1, Big Pickle, DeepSeek V4 Flash Free, Nemotron 3 Super Free
<h4>Requirements</h4>
<ul>
<li>PHP 7.4 or higher</li>
<li>WordPress 7.0 or higher</li>
<li>An <a href="https://opencode.ai" rel="nofollow ugc">OpenCode Zen</a> account and API key</li>
</ul>
<h4>How the WordPress AI Provider System Works</h4>
WordPress 7.0 introduced a built-in AI Client SDK. Plugins and themes call a standard API (e.g. “generate text from this prompt”) without knowing which AI provider is active. Provider plugins like this one register themselves with WordPress and handle the actual API calls.
This means:
<ol>
<li>Install this plugin → OpenCode Zen is registered as an AI provider</li>
<li>Enter your API key in Settings > Connectors</li>
<li>Every AI-enabled plugin on your site can now use OpenCode Zen automatically</li>
</ol>
You can also install multiple provider plugins and switch between them from the Connectors screen — no re-configuration of individual plugins needed.
<h4>Settings</h4>
Go to Settings > OpenCode Zen to configure:
<ul>
<li>Default Model — the model used when no explicit model is requested by a plugin</li>
<li>Temperature — controls output randomness (0.0–2.0, default 0.7)</li>
<li>Max Tokens — maximum tokens in the response (1–200,000, default 4096)</li>
<li>Top P — nucleus sampling threshold (0.0–1.0, default 1.0)</li>
<li>Presence Penalty — penalises repeated topics (-2.0–2.0, default 0.0)</li>
<li>Frequency Penalty — penalises repeated tokens (-2.0–2.0, default 0.0)</li>
</ul>
