Overview
LangChain is an open-source development framework designed to streamline the creation of applications powered by large language models (LLMs). It provides a modular and extensible toolkit for chaining together different components, such as LLMs, prompt templates, data retrieval mechanisms, and agents, to build complex and intelligent applications. Developers, AI engineers, and data scientists utilize LangChain to create advanced conversational agents, question-answering systems over custom data, and workflow automation tools that can interact with external data sources and perform multi-step reasoning.
