Abstract: How Microsoft powers planet-scale AI apps with DiskANN

Join us for a deep dive into DiskANN, the state-of-the-art vector search system powering Microsoft services like Bing Search, Advertisements, and the Bing, M365, and Windows Copilots. We'll discuss the motivation behind DiskANN, explore its cutting-edge design, review the latest performance benchmarks, and provide a sneak peek at upcoming improvements. We'll also examine how DiskANN is integrated into Azure Cosmos DB, delivering a serverless, pay-per-use, high-performance vector database that empowers developers to build intelligent applications at any scale.
