I'm super excited to share my next adventure: Later this month, I'll be joining @vercel.com to work on the AI SDK! 🎉 felix-arntz.me/blog/joining...

Introducing the WordPress AI Client SDK: make.wordpress.org/ai/2025/11/2...

🚀 Announcing the WordPress AI Client SDK (v0.1.0)! It's never been easier to integrate generative AI into your plugins. ✅ Uniform API for any model (OpenAI, Google, etc.) ✅ WP-native fluent prompt builder ✅ Built-in admin screen for API keys Get started now. 👇

We use coding agents daily, for our own engineering efforts, or to power SaaS we build. Yet, almost all of these agents are tied to specific infrastructure - the vendor lock-in is real, flexibility is low. Introducing AI Code Agents, a TypeScript SDK to solve these issues. 👇

I believe the biggest innovations in the AI application layer are happening right now in the TypeScript ecosystem. The AI tooling revolution is finally meeting the web development community somewhere they live. Read more on my perspective and excitement: felix-arntz.me/blog/typescr...

The PHP AI Client SDK version 0.2.0 is out now, with several key enhancements and fixes for more developer convenience. If you haven't yet, give it a try to build your invisible AI features, agents, and workflows in a model agnostic way. Release notes: github.com/WordPress/ph...

Awesome news for OSS projects embracing AI assisted coding: agents.md Finally projects can provide LLM instructions without favoring a specific provider or tool, and without including duplicate instructions files. A simple yet huge step in the right direction. 🎉

If you want to play around with or explore the code of the WordPress AI chatbot agent demo from Matt Mullenweg's #WCUS keynote, here is the GitHub repository: github.com/felixarntz/w... There's also a screencast that shows a few things it can do: youtu.be/LX1kAR4Js98

We are a looking for questions and potential discussion points for the WordPress AI Panel about what we're building, next week at #WCUS: us.wordcamp.org/2025/session... If you have something you'd like to have us discuss or cover, please reply to this thread!

I had a great time doing this Startup Grind webinar about the AI Services plugin for WordPress. Lots of live demos and context for how to use it, how it ties in with the WordPress AI Team efforts, etc. Take a look! www.youtube.com/watch?v=by7Q...

AI Services 0.7.0 is now available! This release adds text-to-speech and speech generation capabilities, as well as web search support to applicable providers. And, for the first time since launch, new providers were added, with Mistral, Perplexity, xAI. wordpress.org/plugins/ai-s...

Tune in this Wednesday to learn more about the latest WordPress Core Performance Team efforts, including the View Transitions plugin!

Looking back at 10 years of contributions to WordPress Core, I feel extremely grateful, but I also feel proud. It made me think about how much giving back to open source can give back to you. I put together some related thoughts and personal stories: felix-arntz.me/blog/open-so...

The WordPress AI team just published our first set of roadmap updates. We're building foundational tools that help developers ship AI-powered features the WordPress way. Let’s break down what we’re working on:

If you're curious what the initial priorities of the WordPress AI Team will be, look no further! Several posts were published earlier on the Make AI blog, with this article providing the comprehensive overview of all the building blocks: make.wordpress.org/ai/2025/07/1...

View Transitions 1.1.0 is out! Adding view transitions for WP Admin (opt-in), control over the transition duration, better interoperability with theme support, and compatibility with reduced motion preferences for accessibility. Give it a try: wordpress.org/plugins/view...

10 years ago today, I got my first props for contributing to WordPress Core. I've been contributing ever since, and it changed my life in so many ways. Here's 10 valuable lessons learned, which will hopefully help other current and future contributors: felix-arntz.me/blog/10-less...

In 24 hours, James LePage, @jeffpaul.com, @swissspidy.bsky.social and myself will be discussing AI and WordPress in a panel as part of the #TheAgencyAdvantage virtual conference. Happening on June 24 at 12pm ET. Join us: www.cloudways.com/en/agency-ad...

I recently migrated the ~80 file JavaScript codebase of the AI Services WordPress plugin to TypeScript - a perfect use-case for AI assistance, for such a beneficial yet tedious task. Read more about how using Cline and Gemini sped things up substantially: felix-arntz.me/blog/migrati...

Coming soon in the View Transitions plugin for WordPress: View transitions for WP Admin! This idea started at the #WCEU Contributor Day, and Mukesh Panchal has been bringing it to fruition. 🎉 Making WP Admin feel like an SPA without it suffering the complexity of being one.

New profile picture (about time)! Thanks to @nilovelez.com for capturing me at #WCEU!

Are you attending #WCEU #ContributorDay today? At the Core Performance Table, the brand new View Transitions plugin will be a key focus for the day. Help test and get involved! I'd love to see you there.

Introducing... View Transitions is the latest WordPress plugin from the Core Performance Team, replacing the hard page loads between URLs with smooth animations to improve UX. Previously this required a complex SPA, now it simply works with a plugin. felix-arntz.me/blog/introdu...

Want AI to generate your ALT text for you? Have a play around with the beta version of our plugin... filter.agency/filter-ai/

Two years ago today, I opened an experimental pull request for a "Speculation Rules" module in the Performance Lab plugin. Little did I know then that it would launch as a key feature of WordPress 6.8 last month. Join me as I share the process behind it: felix-arntz.me/blog/specula...

As a WordPress plugin author, bumping the "Tested Up To" version in the WordPress directory can be tedious, especially if you maintain several plugins. Fortunately you can automate this safely, without risk of deploying other changes. More in this post: felix-arntz.me/blog/deployi...

Weeee my very first AI feature utilizing @felixarntz.bsky.social AI Services plugin. This feature integrates with our new Power Table block (fork of Flexible Table) in our block library to generate captions for Tables given their data and their table name if present.

Are you considering to use AI in your WordPress plugin? Check out the AI Services plugin documentation to get started with a provider agnostic API that you can use in your own plugin: felixarntz.github.io/ai-services/ 🎓

There is a new web platform feature that allows you to build performant and accessible carousels entirely using CSS. Say goodbye to bulky JavaScript slider libraries! As a proof of concept, I built a CSS-only carousel block for WordPress. Go check it out 🚀

AI Services version 0.6.0 is out! This release adds multimodal output, letting you create both text and images using a single model. Other enhancements include PHP+JS code previews in the AI Playground, and updated support for Chrome's built-in AI. wordpress.org/plugins/ai-s...

A revolutionary new AI capability is coming to the AI Services plugin next week: Multimodal output lets you create both text and images using a single model, and it's also way better than regular image models at taking an input image and altering it based on your prompts.

Speculative loading is only one of many performance improvements in WordPress 6.8! Learn more about all things performance that this release has to offer below 👇 This post is the latest in the performance improvements series of WordPress major releases: make.wordpress.org/core/2025/04...

The future of generative AI, or I should rather say the present, is about multimodal inputs and outputs. APIs and SDKs not built with that in mind will need to be rearchitected soon, if not already.

Are you using the WordPress Interactivity API? If so, please read on about what is going to change in WordPress 6.8. Spoiler alert: Performance enhancements incoming! make.wordpress.org/core/2025/03...

I'd love to see more decoupling of AI based tooling from the end underlying AI providers or models used. Tools like Claude Code are great, but I'd love to see tools like this embrace a more agnostic approach, e.g. use @vercel.com's AI SDK to support all kinds of providers.

The vote for the new WordPress Core Performance Team Reps for 2025 is now open: make.wordpress.org/performance/...

Are you developing or maintaining a WordPress plugin that registers multiple block types? Then you probably benefit from using the new `wp_register_block_types_from_metadata_collection()` function that is added in WordPress 6.8. Learn more: make.wordpress.org/core/2025/03...

On the heels of @felixarntz.bsky.social's WP 6.8 Dev Note yesterday and @tunetheweb.com's implementation guide posted today, I wrote up how to extend Speculative Loading in WordPress to enable more instant page loads:

Speculative Loading is coming to WordPress in 6.8, unlocking huge potential to boost your site's performance. The dev note explains how you can prepare your WordPress plugins for the new feature and how you can get the most out of it for your site: make.wordpress.org/core/2025/03...

Did you know that the AI Services plugin is the first (and so far only) WordPress solution to generate images using Google's impressive Imagen models? You can use the models in your own plugin by using the AI Services APIs: wordpress.org/plugins/ai-s... Below are some examples. 👇

Version 0.5.0 of the AI Services plugin for WordPress is out now, and it is the biggest release so far! You can now generate images and implement AI function calling with it - either using its PHP or JavaScript APIs, or by using the AI Playground admin screen. 1/5

StellarWP cut my position today for budgetary reasons. If you know of a role that might be good for me, please send it my way. I’m specifically looking in marketing and community. Thank you! (No hate to Stellar or the folks there. These things suck, but they happen.)

The most difficult thing with pull requests is to not interpret every question, consideration, or higher-level feedback a reviewer leaves as "Please change this". I see it all the time, both as PR reviewer and as PR author when I fall into the same trap.

Haven't tried the AI Services plugin yet? It provides a unified API and abstracted data format, making it incredibly easy for plugin developers to integrate diverse AI capabilities into WordPress. Plus it's open source, free forever, and no ads ever. wordpress.org/plugins/ai-s...

AI image generation is coming to the AI Services plugin, starting with OpenAI's Dall-E and Google's recently published Imagen models! 🎉 You'll be able to explore it in the AI Playground in WordPress, seamlessly integrated with other capabilities like text generation. 1/2

Super stoked for this! Optimization Detective is innovative like few plugins, and it is going to revolutionize how we approach WordPress performance from a technical perspective. But don't take my word for it - check out Weston's #WCAsia talk to see it for yourself!

My plugin is using the AI Services plugin from @felixarntz.bsky.social as the basis for the integrations with Google's Gemini, OpenAI, and Anthropic Claude. Check out his plugin to build your own custom AI flows into WordPress.

🚀 AI-powered alt text generation is already here. It’s a HUGE opportunity to give your site an SEO boost. I built it right into WordPress’s Media Library. It’s not perfect. AI needs human review, but the first to adopt will have an edge before it’s everywhere.
