DGX Spark Live: NYC Spark Hack Winner feature - A 3D time machine for every building in NYC

In this livestream, join one of our NYC Spark Hack winners as he shows how DGX Spark powers The Sixth Borough using desktop GPUs to search, reconstruct, and reimagine New York history in real time. DGX Spark acts as the creative “brain server” for the Time Machine, running local LLMs, vision models, and generative tools so viewers can explore archives and neighborhoods as living, navigable stories. What we’ll cover: - The hackathon-winning vision behind Sixth Borough and what made it stand out - How a single builder reconstructed all 1,082,831 NYC buildings using LiDAR and public datasets - Designing a fully local system: running a 30B language model with no cloud or internet - Turning data into narrative: generating building biographies from civic records - Integrating archival media, including NYPL imagery and historical migration flows - Key technical and creative decisions, tradeoffs, and what made it possible under hackathon constraints
