What is LangSearch?
LangSearch provides a powerful Web Search API designed to enhance Large Language Model (LLM) applications. It delivers high-quality context by leveraging natural language search capabilities across billions of web documents, including news, images, videos, and more. The platform supports hybrid search, combining keyword and vector searches with a semantic reranker to improve search result accuracy.
Its core, the LangSearch Rerank model, is based on transformer architecture. This model boasts exceptional ranking performance typically seen in models with 280M-560M parameters, but with only 80M parameters. This streamlined efficiency translates to significant benefits for users, offering both faster inference speeds and lower operational costs.
