wp_supports_ai() │ WP 7.0.0

Checks whether AI features of WordPress can be used in the current environment.

The function serves as a general check point before starting AI capabilities: generating text, calling AI providers, building prompts, and other LLM scenarios.

By default, AI is considered enabled. You can disable it with the constant WP_AI_SUPPORT or via the filter wp_supports_ai.

If the AI functionality in a plugin or theme is optional, it’s better to check wp_supports_ai() before using it. This way, the code will respect the site-wide settings.

With WP_AI_SUPPORT = false support is hard-disabled (the filter won’t even get a chance).
With WP_AI_SUPPORT = true or if it’s not set, support can be modified via a hook.

Hooks from the function

Returns

true|false.

  • true — AI functions can be used in the current request.
  • false — AI functions are disabled or unavailable.

Usage

wp_supports_ai(): bool;

Examples

0

#1 AI logic check before launch

The example shows how not to run AI code if AI support is disabled on the site.

if ( ! wp_supports_ai() ) {
	return;
}

// You can safely run AI functionality here.
0

#2 Disabling AI via a Constant

The constant is usually set in wp-config.php. After that, wp_supports_ai() will get false unless the value is changed by a filter.

define( 'WP_AI_SUPPORT', false );
0

#3 Disabling AI via a Filter

The example completely disables AI features on the site via the wp_supports_ai filter.

add_filter( 'wp_supports_ai', '__return_false' );
0

#4 Disable AI only in the admin panel

The example disables AI features only for requests in the admin panel.

add_filter( 'wp_supports_ai', 'my_disable_ai_in_admin' );

function my_disable_ai_in_admin( $is_enabled ) {
	if ( is_admin() ) {
		return false;
	}

	return $is_enabled;
}
