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.

Where should @CopilotKit go next? Like Sofia said, many enterprise leaders from non-tech sectors (hospitality, healthcare etc) feel behind on implementing AI into their products. Our goal is to get these industries up to speed to what we see progressing in Silicon Valley. We'll go anywhere to make it happen.

that's a wrap on the conference portion of #LondonTechWeek! we spoke to people from 23 different countries, 59 different industries, and over 180 founders, engineers, and industry leaders at the @CopilotKit booth a common theme from many of the enterprise leaders from non-tech sectors (hospitality, healthcare, etc) is how behind they feel on implementing AI into their products. there is a huge market opportunity here to catch these industries up to speed to what we see progressing in silicon valley it was great to do this event alongside our marketing lead @eli_discovers! being a global company means we don’t always get face to face time with our fellow colleagues, so it’s always nice to have time to chat irl didn't get to meet us at this conference? we'll be at AI Engineer World's Fair in SF next month!

CopilotKit in London 🪁🇬🇧 Amazing talk by @sofiiiiiasz on AG-UI, the Generative UI spectrum and CopilotKit to London's @LangChain community Next up: Generative UI Hackathon at the Google Offices this Saturday! Link below, DM us to get off the waitlist 👇

officially a professional yapper🗣️🗣️ gave a talk on AG-UI and #GenerativeUI at the London @LangChain Community meetup tonight! thanks for putting together a great lineup @sudip_kandel @CopilotKit x LangChain have a deep partnership, 2+ years in the making. we each solved half the stack, and now the seam between us invisible😶‍🌫️

Generative UI isn't one thing. It's a spectrum. Controlled is the predictable end: you build the components. The agent only decides which one to render, and the data it gets. Typed and on-brand. One hook in CopilotKit: useComponent. Learn more about it here 👇 docs.copilotkit.ai/generative-ui

34,063 ⭐ CopilotKit (@CopilotKit) - The frontend stack for agents & generative UI — drop in-app copilots, chat & agentic UX into any React app in minutes 🖥 star-history.com/?repos=Copilot… #starhistory #GitHub #OpenSource #DevTools

Three patterns for defining how much UI an AI agent controls: Mad Libs → Legos → Blank Page. Each is a different answer to: How much of the screen holds still between turns? Framework from @CopilotKit. Best practical writeup by @Saboo_Shubham.

CopilotKit is now in Awesome LLM Apps (114K stars), in the new Generative UI and Agentic Frontends section. This covers where the agent renders, takes input, and streams state back to the user. That's what we build. Thanks @Saboo_Shubham_ for one of the best resources out there for agent builders. Check out the GitHub: github.com/Shubhamsaboo/a…

Completely agree with @tomik99 on this. Especially points 1 & 2. In production AI agent work for e-commerce, we prototype fast using Claude Code + the latest Gemini models, Google ADK and @CopilotKit (AG-UI) to validate ideas fast and cheap. Then we apply real engineering discipline — architecture, testing, security, governance — before anything ships on Cloud Run or #GeminiEnterpriseAgentPlatform. The teams that skip the discipline part are the ones whose projects quietly die in production. The winners combine AI speed with proper engineering foundations. Not one or the other. What’s your experience seeing this shift?

Building products in the AI era: 1. Separate prototyping from production. Vibe code to validate ideas fast and cheap. Then rebuild for production with real engineering discipline. 2. Don't buy AI. Buy engineering. Ask how your partner handles architecture, security, testing,

🎉 @CopilotKit has been trending all weekend All fullstack agent apps in the future will have Agentic UI. Here are a few things people are getting wrong though: → Agentic UI isn't "regenerate every pixel with an LLM." It's an agent in the middle of every interaction. → Generative UI is a spectrum from more control to less: (MORE) invoke existing components -- assemble them -- embed apps via MCP -- generate UI from scratch (LESS) → Token cost is often less than a wall of text. Only the open-ended end is expensive. → The system learns — from user interactions and agent traces — to pick the right point on the spectrum over time. All UI will become AI, and our team is making that happen 👏

My job is to make @CopilotKit grow. I think we're doing that 📈👇 Today, our packages are getting MILLIONS of weekly installs. When I first joined, that number was around 50k. This kind of growth isn't trivial. With AI, building today is easier then ever. What HAS become
