A one-day build event in San Francisco marking the release of Claude Opus 5.5, hosted by Claude Community Events. It opens with Anthropic's launch video and two live demos, then attendees form solo or teams of two to four and pick a track — Delight, Breakthrough or Everyday — before a single continuous build block. There are no talks or breaks. The day closes with one-minute demos from every team, a group photo and build submissions. Each attendee receives $100 in API credits, and feedback from the room is passed to Anthropic's product and model teams. Builds and a recap feed into a roll-up sent across the Ambassador network. Laptops with Claude Desktop and Claude Code are required, along with a console.anthropic.com organization; no API experience is needed. Seats are limited and approval-based.
