LangChain is an open-source framework designed to simplify the development of applications powered by large language models (LLMs). It acts as an orchestration tool, providing a collection of tools and components that allow developers to connect LLMs with various data sources and other tools, enabling the creation of more complex and versatile AI applications

Key characteristics :

• LLM Integration : LangChain provides a standardized way to interact with different LLMs, making it easier to switch between models or use multiple models within the same application
• Data Connection : It allows LLMs to access and utilize external data sources, including databases, APIs, and even real-time information, without needing to retrain the models.
• Chaining Components : LangChain enables the chaining of multiple LLM calls and other components to create complex workflows, such as conversational agents, question-answering systems, and automated data analysis tools
• Modular Design : LangChain's modular architecture allows developers to easily swap out or customize components, making it flexible and adaptable to different application needs
