LangChain is an open-source framework designed to facilitate the development of applications powered by large language models (LLMs). It offers a suite of tools, components, and interfaces that simplify the construction of LLM-centric applications. With LangChain, it becomes effortless to manage interactions with language models, seamlessly link different components, and incorporate resources such as APIs and databases. Now we integrate our Hippo with LangChain Python packages, making Hippo more suitable for developers across the spectrum of expertise.
