AI Provider for Xiaomi MiMo

Xiaomi MiMo (小米 MiMo) as a provider for the WordPress AI Client: text generation and multimodal understanding with MiMo models.

What it does

• Fetches the model list live from GET /v1/models, so newly released models show up on their own.
• Text generation and chat history, including tool calling, structured output (JSON mode) and stop sequences.
• Vision input with the mimo-v2.6-* family and mimo-v2.5, so Alt Text Generation works.
• Reasoning output (reasoning_content) surfaces as thought parts instead of being mixed into the answer text.
• A Settings → AI Provider for Xiaomi MiMo page with three options: the API host (standard API or one of the Token Plan clusters), the thinking mode, and the structured-output mode.

Requirements

• WordPress 7.0 or newer, with the PHP AI Client SDK (bundled in WordPress 7.0, or provided by the AI plugin)
• PHP 7.4 or newer
• A Xiaomi MiMo account with API access

Install

Download the zip from Releases and upload it through Plugins → Add New → Upload Plugin, or copy the plugin folder to wp-content/plugins/ai-provider-for-xiaomimimo/. Activate it, then open Settings → Connectors, open the Xiaomi MiMo card and paste your API key.

Settings

Settings → AI Provider for Xiaomi MiMo has three options. Each is overridden by its matching environment variable when one is set.

The choice is stored per site and is used for the model list and every generation request. A value outside this list falls back to the default. The plugin's row on the Plugins screen also has a Setup Token Plan shortcut to the page.

Configuration

The API key is read in order of precedence from:

1. the XIAOMIMIMO_API_KEY environment variable
2. the XIAOMIMIMO_API_KEY PHP constant
3. the connectors_ai_xiaomimimo_api_key option (Settings → Connectors)

The remaining settings are environment variables or PHP constants:

Changing a setting does not invalidate the AI Client's cached model list; run wp cache flush if a new value does not take effect.

To change which model the AI plugin picks for its features, use the standard filter — this plugin already puts its preferred model first:

add_filter( 'wpai_preferred_text_models', function ( $models ) {
    array_unshift( $models, array( 'xiaomimimo', 'mimo-v2.6-flash' ) );
    return $models;
} );

Notes and limitations

• Authentication uses Authorization: Bearer <key>. MiMo also documents a custom api-key header; both work, and the SDK's default API-key authentication sends the Bearer header.
• Structured output. MiMo implements OpenAI JSON mode (response_format: {"type":"json_object"}) but not schema-constrained output. Features that ask for a JSON schema are downgraded to json_object; if a feature returns nothing, try setting Structured output to None or point that feature at another provider.
• Thinking is on by default on MiMo's side and forces temperature/top_p to the model's own defaults. Set Thinking to Disable (or XIAOMIMIMO_THINKING=disabled) when you need those parameters to apply.
• Not implemented: image generation (MiMo serves none) and the ASR/TTS speech families. The speech models still appear in the model list, but with no capability they can never be selected.

Data and privacy

Prompts you send to the AI, plus whatever the calling plugin or theme adds to them (system instructions, conversation history, tool definitions, attached files), are sent to Xiaomi MiMo. Your API key is stored on your own site and is only ever sent to the host configured above. Nothing is sent until your site actually asks the AI Client for a generation.

Development

php scripts/selfcheck.php                                                     # logic checks, no WordPress needed
php scripts/selfcheck.php --sdk=/path/to/php-ai-client                        # plus live-SDK checks

The self-check asserts model classification, sort order, the declared capabilities and options, the settings resolution, and the request shapes for chat and vision. It needs neither WordPress nor an API key.

Release: push a tag matching the plugin version (git tag v<version> && git push origin v<version>). The release workflow verifies the tag against Version:/Stable tag:, verifies a matching changelog entry exists, builds the plugin zip and publishes it.
