TypeScript is the New Language of the AI Frontier, and I'm Excited - felix-arntz.me From AI SDK to generative UI: The TypeScript ecosystem is shaping up to be at the forefront of AI application development.

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.

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:

AGENTS.md AGENTS.md is a simple, open format for guiding coding agents. Think of it as a README for agents.

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. 🎉

Both of the underlying WordPress projects, the PHP AI Client SDK and the Abilities API, are available now in a first release:

github.com/WordPress/ph...

github.com/WordPress/ab...

Remember this is only a demo, so it has access to a few limited tools. But it's not meant to be a comprehensive agent implementation that can do everything you might want. It's an example for what's possible.

There's also a screencast that shows a few things it can do:

YouTube video by TorontoDigits Academy Webinar - The AI Services Plugin for WordPress: Build Smarter, Not Harder

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...

You may be wondering how AI Services fits into the new WordPress AI Team: The new PHP AI Client SDK (github.com/WordPress/ph...) is heavily inspired by it. In the long term, AI Services will either become a canonical plugin, or its features will be ported into new canonical plugins.

AI Services 0.7.0 brings enhanced support for the Chrome and Edge built-in models, which run directly in your browser. You can now load the plugin's JS API in a "client-side-only" mode, suitable for enabling AI features for any visitors without incurring cost, privacy-friendly.

For developers, the 0.7.0 release might well be the biggest one yet, with tons of API enhancements to simplify implementing support for additional providers. And if your plugin's AI features rely on AI Services, your users have access to the new built-in providers right away.

AI Services Makes AI centrally available in WordPress, whether via PHP, REST API, JavaScript, or WP-CLI - for any provider.

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.

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

How Open Source Contributions Elevate Your Professional Journey - felix-arntz.me Contributing to an open source project can drastically enhance your professional development and career. I share my personal experience here.

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:

PHP AI Client The PHP AI Client SDK provides a unified interface for AI integration across all providers – users choose their preferred AI service while developers focus on building features, not infrastru…

For me personally, my main focus will be building the PHP AI Client SDK, a provider agnostic SDK to communicate with any generative AI models of various capabilities using a uniform API.

Learn more about that project here: make.wordpress.org/ai/2025/07/1...

AI Building Blocks for WordPress We’re creating technical Building Blocks that will allow users and developers to create powerful AI implementations within WordPress.

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...

Then you got nothing to worry about with this plugin :)

I'm not familiar with barba.js. This plugin uses the browser built-in View Transitions API, in other words it's likely far lighter than any framework or SDK could be.

See developer.chrome.com/docs/web-pla... for more information.

View Transitions Adds smooth transitions between navigations to your WordPress site.

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.
