New Delhi | Claude Build Day

Fable 5.1 just shipped. Let’s build on it with Claude Code before the rest of the world finishes reading the launch post. We’re bringing developers together in New Delhi to push Anthropic’s newest model on Claude Code. This is a Build Day: no long talks, no passive watching. You show up, see what the model can actually do, and build something real with it the same week it lands. How the day runs (10:00 AM to 4:00 PM): We’ll start by watching Claude Code build something genuinely hard in front of you. Think a Newtonian star-system simulator, a webcam-powered hand-motion orchestra conductor, or a thermodynamically accurate engine—each shipped as a single, self-contained file. Then the room takes over. Pick a track and build solo or in a team of two to four: Delight — Build something surprising, beautiful, or fun. The bar is that you couldn’t have made it this good, this fast, before. Breakthrough — Build something you couldn’t build before. Bring the problem the last model choked on and see how far this one gets. Everyday — Build something that solves a real problem in your life or workflow. We’ll close with two-minute demos from everyone who built something, an optional judged round for the competitive crowd, a group photo, and the good kind of arguing about what to build next. Every attendee gets $100 in Anthropic API credits to build with during the event. Who this is for: Developers and builders—people who live in Claude Code, ship with the API, or are building agents. An active Claude subscription is a plus, so bring it if you have one. Bring your laptop, your charger, and one idea you’ve been itching to try.
