LangChain

LangChain is an open-source framework designed to help developers build applications powered by large language models (LLMs). It simplifies the process of chaining together interoperable components, such as models, embeddings, and vector stores, to create sophisticated AI applications. This tool is for developers looking to rapidly prototype and deploy LLM-powered solutions with flexible abstraction layers and production-ready features. Developers are excited by its modular architecture and vast integration library which speed up AI application development and ensure future-proofing.
