Anthropic reveals the winners of its first Built with Opus 4.6 Claude Code hackathon, run in partnership with Cerebral Valley. Five winners — including a personal injury lawyer, a cardiologist, a roads specialist, an electronic musician, and a software engineer — each built real-world tools in one week using Claude Code. First place went to CrossBeam, an AI-powered California housing permit assistant built by a lawyer who wrote zero lines of code. Other winners include Elisa (a visual block-based IDE for kids), PostVisit.ai (a post-appointment healthcare tool), TARA (AI road infrastructure appraisal from dashcam footage), and Conductr (a real-time AI virtual bandmate). Four of the five winners were not professional developers. A follow-up hackathon featuring Opus 4.7 is already underway.
