LangChain

LangChain is an open-source framework designed to simplify the creation of applications using large language models (LLMs). It provides a standard interface for chaining together different components, such as LLMs, APIs, and data sources, to build complex AI-driven applications. LangChain supports modular components like models, prompts, memory, indexes, chains, and agents, enabling developers to create context-aware and reasoning applications. It is widely used for tasks such as chatbots, question-answering systems, document analysis, and automation workflows. LangChain also offers integrations with various LLMs, vector databases, and tools to enhance functionality.
