One of the key components of Microsoft’s Copilot Runtime edge AI development platform for Windows is a new vector search technology, DiskANN (Disk Accelerated Nearest Neighbors). Building on a long-running Microsoft Research project, DiskANN is a way of building and managing vector indexes inside your applications. It uses a mix of in-memory and disk storage to map an in-memory quantized vector graph to a high-precision graph help on disk.
