I've been working with @AlemTuzlak on our new Bots SDK. It lets you bring any AG-UI-compatible agent to Slack and Microsoft Teams. Google Chat, Discord, and more are coming soon!
Slack 🤝 AG-UI Protocol @SlackHQ is now a first-class AG-UI frontend with: → Streaming replies → Tool calls → Human in the Loop approvals → Full thread context Same agent you built for the web, now living where your users actually work.

"Build me a Snake game in Vite React" → game runs inside the chat. "Make it red themed" → the running game updates live. We worked with @CopilotKit to build a generative-UI coding agent backed by @daytonaio sandboxes. Every tool call streams as a live card. So does the running app.

Claude Fable (Mythos) 5 Open Generative UI You type, the model builds the UI. That's the whole demo 👇 github.com/CopilotKit/OpenGe…
Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use. Its capabilities exceed those of any model we’ve ever made generally available.

To allow agents to generate native UI beyond just text, we are building A2UI compose render. We caught up with the team from CopilotKit to talk about bringing A2UI to mobile. Check out the code → goo.gle/4wRTqzd

Make your Agent speak your UI Many open source SDKs give you a simple chat UI But only @CopilotKit lets you bring fully-immersive Claude and Cursor-like agentic experiences into your own apps. Here's a thread on how to do, it in one sitting 🧵

I get to work with such a stacked team at @CopilotKit. Pumped for today's launch. 🚀
We've raised $27M to build @CopilotKit — the Agentic Frontend Stack connecting humans & agents. Because all UI will be AI. Co-led by Glilot Capital, NfX and SignalFire.

Redux was always the right blend of pain-for-gain for me. The pain was the amount of code you had to write by hand and the complexity it entailed. The gain, however, was a level of predictability and safety that I felt comfortable with. Agentic coding is pushing me toward better architectural choices because I can manufacture code on demand and use conversations to quickly rebuild my mental model of the codebase. For example, @DavidKPiano's XState is just a joy to use with agents. I can generate and validate state machines in natural language, then use them to guide and validate agents' plans. Similarly, leaning into @CoqLang to write validation engines for protocols. Why not have a body of theorems you can prove to validate critical contracts? Articulating ideas with these tools wasn't the hard part: it was my slow transfer speed from idea to implementation.

A lot of teams have moved past trying AI and are now trying to make it hold up in production. What actually works once #AI is part of real systems? What still feels unstable? What do teams have to change to make it reliable across the full workflow? On May 7, @ElliottFouts, @mikeryandev, and @dkundel are talking through what they’re seeing firsthand and how teams are adapting as this moves from experimentation into day-to-day use! 📅 May 7 · 12:30 PM ET RSVP: luma.com/1thfunkv

I've joined @CopilotKit as director of product to build generative UI! Ridiculously excited to get back to my frontend roots while staying at the forefront of agentic development. Post linked below on why I'm betting big on generative UI 🔗
