What KDB.AI is
KDB.AI is a vector database and search engine for building AI applications with real-time data. Its hybrid search combines dense and sparse vector search with metadata filtering and temporal similarity search. It supports retrieval-augmented generation with unstructured text, video, audio, and image data. Listed indexes include Flat, qFlat, IVF, IVFPQ, HSNW, and qHSNW; documented integrations include LangChain, Vector IO, and LlamaIndex. KDB.AI also integrates NVIDIA cuVS for GPU-accelerated vector search. The maker presents research assistants, portfolio management, real-time alpha and beta extraction, and image processing as use cases. Deployment options include a managed Cloud Starter Edition and self-managed Server Standard Edition. The free cloud plan provides 4 GB of RAM, 30 GB of storage, and a 10 MB query size. Its agreement does not commit to service availability or uptime and provides the service without warranty. Support is available through a Slack community or [email protected]. The platform is offered through an API, web, and self-hosted deployment.
