What is Vespa.ai?

Vespa.ai is an AI Search Platform designed for developing and operating large-scale applications that integrate big data, vector search, machine-learned ranking, and real-time inference.

Its core capabilities include hybrid search combining vector similarity with structured data, distributed machine-learned model inference, and seamless integration of text, vector, and structured data.
