Opus plans. Sonnet ships.India's first ever Build Day featuring both Claude Opus 5.5 and Claude Sonnet 5.5 is here, and this is the room where you find out what they can really do. Use Opus for deep reasoning and planning, Sonnet for fast execution, or mix them however you like. Join fellow builders in Mumbai for a fast, hands-on evening of building on the newest Claude models, while the rest of the world is still reading about them.

How it works:We'll kick off with a quick look at what's new and a couple of live demos, then it's straight into building. Pick one of three tracks and build something of your own that pushes the new models:

  • Delight: Build something surprising, beautiful, or fun that you couldn't have made this good, this fast, before.

  • Breakthrough: Bring a problem older models couldn't crack and see how far the new ones get.

  • Everyday: Build something that solves a real problem in your life or work.

Work solo or form a team on the spot. We close with quick two-minute demos where everyone shows what they shipped.

Who should attend:Developers, engineers, and builders who use Claude Code, the Claude API, or are building agents.

Perks:Every approved attendee receives $100 in Claude API credits to build with on the day.

Before you arrive:Bring your laptop charged and set up an account at console.anthropic.com with an Organization created. Credits attach to your Organization, not a personal Claude.ai account, so doing this beforehand means you're building from minute one.

Seats are limited and registrations are reviewed and approved, so register early.
