LangChain is a powerful and flexible framework for building applications that use large language models (LLMs). LangFlow is a visual interface built on top of LangChain, enabling users to design and deploy LLM-based workflows without writing extensive code.

Features of LangChain & LangFlow:

• Modular and Composable: LangChain allows you to combine LLMs with tools, APIs, and memory in a structured way.
• Visual Interface: LangFlow offers a drag-and-drop UI for creating and managing complex chains easily.
• Data-Aware and Agent-Based: Enables interaction with external data sources and dynamic decision-making through agents.
• Open-Source and Extensible: Actively maintained with support for custom components and community plugins.

Activate your virtual environment: source lang_env/bin/activate

To check the version: pip show langchain and pip show langflow

Disclaimer: LangChain and LangFlow are open-source tools released under permissive licenses. They are actively maintained by a growing community of developers, researchers, and AI enthusiasts. Their capabilities make them ideal for building intelligent, LLM-powered applications and workflows.
