WordPress 7.0 RC1 Is Live: Built-In AI Client API Lets Plugins Generate Text & Images Without Managing Keys

WordPress 7.0 RC1 Drops — And It Ships a Native AI Client API

WordPress 7.0 Release Candidate 1 officially landed on March 24, 2026, bringing 134+ fixes since Beta 5 and two headline additions that weren’t in the original beta: a new AI Connectors Screen and a fully built-in AI Client PHP API. The final release is still on track for April 9, 2026.

What’s New in RC1

  • AI Connectors Screen — A new Settings > Connectors admin screen lets site owners connect AI providers (Anthropic, Google, OpenAI) without plugins needing to handle API keys.
  • Command Palette via ⌘K / Ctrl+K — The Command Palette is now accessible from the admin bar globally, not just inside the editor.
  • Real-Time Collaboration is opt-in by default — RTC now requires a WP_ALLOW_COLLABORATION constant or activation hook to enable, addressing earlier performance concerns.
  • 134+ bug fixes and improvements since Beta 5, including OPCache info in Site Health and improved revision diffing.

The Big Developer Story: WordPress 7.0’s Built-In AI Client API

The most significant developer-facing addition detailed in the March 24 dev notes is wp_ai_client_prompt() — a provider-agnostic PHP API bundled directly into WordPress Core. Here’s what it means for plugin developers:

Generate Text in One Line

$text = wp_ai_client_prompt( 'Write a summary of this post.' )
    ->using_temperature( 0.7 )
    ->generate_text();

Generate Images

$image = wp_ai_client_prompt( 'A futuristic WordPress logo in neon style' )
    ->generate_image();

echo '<img src="' . esc_url( $image->getDataUri() ) . '">';

Key Design Principles

  • No credential management — API keys are handled by the Connectors API. Plugins just call the API.
  • Provider-agnostic — Use using_model_preference() to hint at preferred models; WordPress falls back gracefully if unavailable.
  • Feature detection — Call is_supported_for_text_generation() before showing AI UI to avoid errors on sites without configured providers.
  • WordPress conventions — Returns WP_Error on failure, integrates with hooks, and works with rest_ensure_response().
  • Multimodal support — Text, images, speech, and video generation are all supported via the same fluent builder.

Official AI Provider Plugins

WordPress Core doesn’t bundle AI providers directly. Three official provider plugins are available:

How to Test RC1

Install the WordPress Beta Tester plugin, select “Bleeding edge” channel and “Beta/RC Only” stream — or download the RC1 zip directly. Do not test on production sites.

Key Takeaway: WordPress 7.0 is positioning itself as an AI-native CMS. The built-in AI Client API means plugin developers can ship AI-powered features without reinventing credential management or provider integrations — a significant shift for the ecosystem.
