Vespa is an open-source AI search platform combining hybrid retrieval, multi-phase ranking, and machine-learned inference in a distributed engine.
Vespa is a distributed serving engine that unifies keyword, vector, and structured search with machine-learned ranking and real-time inference in a single platform. Applications declare their schemas, rank profiles, and deployment topology in application packages, so retrieval logic ships and versions as code.
The engine serves queries and continuous indexing on the same horizontally scaled cluster, with deployments measured at thousands of queries per second and latencies below 100 milliseconds. Teams run it self-managed through the open-source project or managed on Vespa Cloud for search, RAG, and recommendation workloads.
