Pros

    Vespa.ai

    Developers building customer-facing, large-scale search, Retrieval-Augmented Generation (RAG), and recommendation systems face a core challenge: retrieving and operationalizing data in real time. Data is fragmented across formats, including PDFs, free text, and semi-structured sources. This makes it difficult to unify, index, and serve data efficiently to applications and end users. Without the right infrastructure, applications become slow, brittle, and costly to scale.
