AI Provider for MiniMax – AI Connector for M3, M2 & Image Models

This plugin is an AI connector for MiniMax. It registers MiniMax with the WordPress AI Client, so every AI-enabled plugin on your site can generate text and images through MiniMax — text generation, chat, image understanding on MiniMax-M3, and image generation with image-01.

This plugin is an independent, third-party integration and is not affiliated with, endorsed by, or sponsored by MiniMax.

Why MiniMax?

MiniMax is an AI company known for its high-performance, cost-effective language models. The MiniMax M2 and M3 series deliver 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:

• Long-context tasks — handling large documents, long conversations, and extended content generation
• Instruction following — precise, structured output generation suitable for automated pipelines
• Multilingual content — strong performance in English, Chinese, and other languages
• Creative writing — rich, nuanced prose generation for blogs, marketing copy, and storytelling

Features

• MiniMax M2 and M3 series models — including Highspeed variants optimised for faster responses
• Automatic model discovery — live model list fetched from the MiniMax API and cached hourly; falls back to a hardcoded list when offline
• Full parameter control — temperature, max tokens, top P, thinking mode, service tier, system instruction, and function declarations
• Chat history — multi-turn conversations, not just single prompts
• Image generation — image-01, with aspect ratio, orientation and multiple candidates
• Settings page — configure default model and generation parameters without touching code
• API key via Connectors — enter your key once in Settings > Connectors; all AI-enabled plugins share it automatically
• Environment variable support — MINIMAX_API_KEY for server-level configuration, bypassing the database entirely
• OpenAI-compatible API — uses the standard OpenAI API protocol for broad compatibility
• Highspeed variants — M2.7 Highspeed, M2.5 Highspeed, and M2.1 Highspeed for latency-sensitive applications

What Can You Do With AI in WordPress?

Once this provider is configured, any WordPress plugin or theme that integrates with the WordPress AI Client can use it:

• Block editor (Gutenberg) — AI writing assistance, rephrasing, summarising, and expanding content
• WooCommerce — generate product descriptions, SEO meta titles, customer review summaries, and category descriptions
• SEO plugins — generate meta descriptions, focus keyphrases, and Open Graph content
• Customer support — power AI chatbots and automate FAQ responses
• Translation and localisation — translate and adapt content for English, Chinese, and other markets
• Content marketing — generate blog post drafts, social media copy, and email newsletters
• Image alt text — generate accessible alt attributes for media library images

Supported Models

When an API key is configured, the live model list is fetched directly from the MiniMax API, so you always see the latest models. If the API is ever unavailable, a built-in fallback list of 8 models keeps everything working — the MiniMax-M3 flagship plus the M2 series (M2.7, M2.5, M2.1, and M2), each with an optional Highspeed variant tuned for lower latency.

See the full model catalogue for every model ID. Not sure which to pick? See the FAQ below.

Requirements

• PHP 7.4 or higher
• WordPress 7.0 or higher
• A MiniMax account and API key

How the WordPress AI Provider System Works

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:

1. Install this plugin → MiniMax is registered as an AI provider
2. Enter your API key in Settings > Connectors
3. Every AI-enabled plugin on your site can now use MiniMax automatically

You can also install multiple provider plugins and switch between them from the Connectors screen — no re-configuration of individual plugins needed.

Settings

Go to Settings > MiniMax to configure:

• Default Model — the model used when no explicit model is requested by a plugin
• Temperature — controls output randomness (0.0–2.0, default 0.7)
• Max Tokens — maximum tokens in the response (1–1,000,000, default 4096)
• Top P — nucleus sampling threshold (0.0–1.0, default 1.0)
• Thinking — whether MiniMax-M3 reasons before answering; disabling it is faster and cheaper (adaptive or disabled, default adaptive)
• Service Tier — standard, or priority routing at 1.5x the cost (default standard)

For Developers

This plugin follows the official WordPress AI Provider pattern and works with any plugin built on the WordPress AI Client SDK. It registers the minimax provider and supports the generation options MiniMax actually honours (temperature, max tokens, top P, system instruction, and function declarations). Presence and frequency penalties and stop sequences are deliberately not declared, because MiniMax documents them as ignored.

External Services

This plugin connects to the MiniMax API (https://api.minimax.io/v1) to:

1. Retrieve the list of available AI models (cached for 1 hour via WordPress transients)
2. Send text generation requests using your configured model

Service: MiniMax API endpoint: https://api.minimax.io/v1 When data is sent: When generating AI text or refreshing the model list Data sent: Your API key (via Authorization header) and the text prompt/conversation Terms of Service: platform.minimax.io/protocol/terms-of-service Privacy Policy: platform.minimax.io/protocol/privacy-policy

No data is sent to the MiniMax API until you enter an API key and a WordPress feature triggers a text generation request.
