Vespa is Big Data + AI, online. At any scale, with unbeatable performance. The Vespa.ai Team is located in Trondheim, Norway, and is built of 29 dedicated people. It is developing Vespa and running the Vespa Cloud, helping our users to implement online big data serving.

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.

Recommendation, personalization and targeting involves evaluating recommender models over content items to select the best ones. Large language models are revolutionary, but their usefulness for real tasks is limited by their lack of memory, trustworthiness, specific knowledge, and ability to reason in many steps. To make more useful agents we must give the models the ability to store and search vector and text data in real time.
