Al Amin Ahamed

This plugin provides <a href="https://www.minimax.io/" rel="nofollow ugc">MiniMax</a> integration for the WordPress AI Client. It enables WordPress sites to use MiniMax’s high-performance large language models for text generation, content creation, and other AI capabilities through an OpenAI-compatible API.
This plugin is an independent, third-party integration and is not affiliated with, endorsed by, or sponsored by MiniMax.
<h4>Why MiniMax?</h4>
MiniMax is an AI company known for its high-performance, cost-effective language models. The MiniMax M2 series delivers frontier-level text generation quality — competitive with top models from OpenAI and Anthropic — while offering attractive pricing for high-volume WordPress use cases.
MiniMax models are particularly strong at:
<ul>
<li>Long-context tasks — handling large documents, long conversations, and extended content generation</li>
<li>Instruction following — precise, structured output generation suitable for automated pipelines</li>
<li>Multilingual content — strong performance in English, Chinese, and other languages</li>
<li>Creative writing — rich, nuanced prose generation for blogs, marketing copy, and storytelling</li>
</ul>
<h4>Features</h4>
<ul>
<li>MiniMax M2 and M1 series models — including Highspeed variants optimised for faster responses</li>
<li>Automatic model discovery — live model list fetched from the MiniMax 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>MINIMAX_API_KEY</code> for server-level configuration, bypassing the database entirely</li>
<li>OpenAI-compatible API — uses the standard OpenAI API protocol for broad compatibility</li>
<li>Highspeed variants — M2.7 Highspeed, M2.5 Highspeed, and M2.1 Highspeed for latency-sensitive applications</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 — generate product descriptions, SEO meta titles, customer review summaries, and category descriptions</li>
<li>SEO plugins — generate meta descriptions, focus keyphrases, and Open Graph content</li>
<li>Customer support — power AI chatbots and automate FAQ responses</li>
<li>Translation and localisation — translate and adapt content for English, Chinese, and other markets</li>
<li>Content marketing — generate blog post drafts, social media copy, and email newsletters</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 MiniMax API. The built-in fallback list includes:
<ul>
<li>MiniMax-M2.7 — latest generation, highest capability</li>
<li>MiniMax-M2.7 Highspeed — M2.7 performance at lower latency</li>
<li>MiniMax-M2.5 — balanced performance and cost</li>
<li>MiniMax-M2.5 Highspeed — M2.5 with faster response times</li>
<li>MiniMax-M2.1 — cost-effective mid-tier model</li>
<li>MiniMax-M2.1 Highspeed — M2.1 with reduced latency</li>
<li>MiniMax-M2 — previous generation, widely supported</li>
<li>MiniMax-M1 — foundation model</li>
<li>MiniMax-Text-01 — specialised text generation model</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>PHP 7.4 or higher</li>
<li>WordPress 7.0 or higher</li>
<li>A <a href="https://www.minimax.io/" rel="nofollow ugc">MiniMax</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 → MiniMax 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 MiniMax 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 > MiniMax 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>
