LangChain

# Build Intelligent Applications with LangChain​LangChain is an open-source framework designed to simplify the development of applications powered by large language models (LLMs). It provides developers with a suite of tools and abstractions to integrate LLMs with external data sources, APIs, and computational resources.Key components of LangChain include:- **Chains**: Sequences of calls to LLMs and other tools, enabling complex workflows.- **Agents**: Entities that use LLMs to make decisions about which actions to take and in what order.- **Tools**: Interfaces that allow agents to interact with external systems, such as databases, APIs, or file systems.LangChain supports various use cases, including chatbots, document analysis, code understanding, and more. Its modular design allows for easy customization and extension, making it suitable for both research and production environments.
