Python LangChain

Python LangChain is a comprehensive framework for building large language model-powered applications that provides standardized interfaces, interoperable components, and orchestration tools for AI development. LangChain is a framework for building LLM-powered applications. It helps you chain together interoperable components and third-party integrations to simplify AI application development. The framework consists of core components including prompt templates, chains, agents, memory systems, and document loaders that work together through the LangChain Expression Language (LCEL). LangChain is a Python library and framework that aims to empower developers in creating applications fueled by language models, with a particular focus on large language models like OpenAI’s GPT-3. Python LangChain enables developers to create data-aware applications that connect LLMs to external data sources and agentic systems that allow models to interact with their environment, supporting use cases from chatbots to complex multi-agent workflows.
