LangChain is a library designed to assist developers in building applications through the use of large language models (LLMs) and composability. It provides a standard interface for building chains of LLM calls and integrating them with other tools, enabling developers to build powerful apps that combine LLMs with other sources of computation or knowledge. LangChain includes end-to-end examples for common applications such as question answering, chatbots, and agents. It also provides documentation on getting started, how-to examples, and API reference. With LangChain, developers can take advantage of LLMs in ways that were previously impossible and build innovative applications that leverage the power of these models.
