What is LangChain

LangChain is a software framework that helps facilitate the integration of large language models (LLMs) into applications. LangChain is a framework for developing applications powered by large language models (LLMs). This open-source platform provides developers with standardized components, templates, and tools to build sophisticated AI applications that leverage conversational AI, document analysis, code generation, and data retrieval capabilities. LangChain simplifies the complexity of connecting LLMs with external data sources, APIs, and custom business logic through its modular architecture. The framework enables seamless chaining of multiple AI operations, allowing developers to create context-aware reasoning systems that can process complex workflows, maintain conversation state, and execute multi-step tasks with enhanced reliability and performance optimization for production-grade AI applications.
