Vespa.ai

You can build search applications, generative AI and RAG applications, recommendation and personalization systems, semi-structured navigation for e-commerce, and personal or private search applications.

Vespa scales to billions of constantly changing data items with thousands of queries per second and latencies below 100 milliseconds. It uses a C++ core engine managing memory and implementing core indexing and searching algorithms. Distributed functions execute locally where data is stored, enabling any scale without impacting quality or latency.

Vespa improves search relevance through hybrid search combining vector similarity, relevance models, and multi-vector representations without limitations. It generates ranking signals from matching various fields and combines them using mathematical functions or machine-learned models in formats like ONNX or XGBoost.

Vespa Cloud provides fully managed hosting with automatic handling of operational concerns from node procurement to failover between global regions. It includes encryption of data at rest and in transit, node and endpoint certificates for securing communication, automatic OS patches, continuous platform upgrades four times per week, and 24-7 customer support.

Yes, applications can run on Vespa Cloud on Vespa-managed AWS and GCP accounts, but Vespa also uniquely supports deploying applications where the data plane and data reside entirely in customer-owned dedicated accounts, combining operational advantages with security and compliance benefits.
