Why DataStax Loves LangChain

Recent market developments indicate a growing demand for end-to-end retrieval augmented generation (RAG) solutions, as evidenced by software vendors like DataStax introducing new offerings in this space. LangChain, an open source framework for developing applications powered by language models, has seen massive adoption among startups and large enterprises alike. Approximately 87% of DataStax's vector search production customers use LangChain. The growing popularity of LangChain is due to its ability to enable advanced RAG techniques that reduce hallucinations and leverage both structured and unstructured data, making it easier for businesses to move from prototypes to production. As the ecosystem evolves, LangChain is becoming more modular with separate packages for integrations, allowing companies like DataStax to independently add features without breaking the project. DataStax aims to contribute technical expertise to the project and help conduct benchmarking to determine which RAG techniques work best in practice.
