We
Make AI
Work
Vespa.ai is an AI Search Platform for developing and operating large-scale applications that combine big data, vector search, machine-learned ranking, and real-time inference. With native tensor support for complex ranking and decisioning, Vespa enables real-time AI applications like RAG, recommendation, and intelligent search—at enterprise scale.
-
+ Search
Vespa is the world’s leading open text search engine and the world’s most capable vector database. In combination with Vespa’s integrated distributed machine-learned model inference for relevance this lets you create search applications with a quality you simply cannot achieve in any other way.
-
+ Generative AI (RAG)
GenAI applications are only as good as the data we surface for them to work with; they need great search relevance. This takes much more than vector similarity—hybrid search, relevance models, and multi-vector representations. Vespa is the only platform which lets you deploy such techniques with no limitations and at any scale.
-
+ Recommendation and personalization
Recommendation, personalization and ad targeting systems combine retrieval of eligible content with machine-learned model evaluation to select the best data items. Vespa lets you easily build applications that do this at any scale and complexity.
-
+ Semi-structured navigation
Applications like e-commerce use a combination of structured data and text+images, and need to combine search and recommendation seamlessly with structured navigation. Vespa provides all the features required to do this with great performance, at any scale.
-
+ Personal/private search
In applications working with personal data, any query will only access a small fraction of the total data, and building indexes would be wasteful – especially with vectors. Vespa provides a special mode – streaming search – which delivers all the industry-leading features of Vespa for personal/private search 20x cheaper than with indexing.
All you need to build data-driven applications
