LangChain Framework

LangChain Framework is an open-source Python and JavaScript library designed to streamline the development of applications powered by large language models (LLMs). This modular framework provides developers with pre-built components, chains, and agents that simplify complex AI workflows including document processing, conversational interfaces, and autonomous task execution. LangChain Framework abstracts the complexity of LLM integration through standardized interfaces for prompt management, memory systems, and external tool connectivity. The framework enables rapid prototyping and production deployment of sophisticated AI applications that can chain multiple LLM calls, maintain conversation context, integrate with vector databases, and execute multi-step reasoning tasks with built-in error handling and observability features.
