Vespa.ai

Vespa.ai provides an AI-based search platform that allows applications leveraging AI and data online to store, search, and apply unlimited quantities of data to meet their users’ needs in real time.

Vespa is a fully featured search engine and vector database. It supports vector search (ANN), lexical search, and search in structured data, all in the same query. Integrated machine-learned model inference allows you to apply AI to make sense of your data in real time. Together with Vespa's proven scaling and high availability, this empowers you to create production ready search applications at any scale, and with any combination of features.

Vespa offers an integrated approach for applying AI to data during serving time, using vectors, tensors, text, structured data or any combination to provide high-quality solutions catered to diverse use cases, from search and retrieval-augmented generation (RAG) to recommendation and ad targeting. Vespa takes responsibility for the needs of applications from end to end, including managing the data and performing model inferences directly where it resides, allowing applications developed on Vespa to scale to any amount of data, load or complexity.
