These products provide search algorithms, reranking libraries, vector compression, and low-level performance optimizations for data indexing. They are designed for machine learning engineers and developers building high-accuracy retrieval and RAG pipelines. This cluster focuses on the technical mechanics of search and information retrieval rather than end-user conversational AI applications.
