Overview
LangChain is a framework for building agents and LLM-powered applications. It helps developers chain together interoperable components and third-party integrations to simplify AI application development while aiming to future-proof decisions as the underlying technology evolves. The framework provides a standard interface for models, embeddings, vector stores, and more, allowing developers to work at different levels of abstraction. It is part of a broader ecosystem that includes Deep Agents, LangGraph, and LangSmith.
Key features
- Real-time data augmentation via integrations with model providers, tools, vector stores, and retrievers
- Model interoperability allowing models to be swapped during experimentation
- Modular, component-based architecture for rapid prototyping
- Production-ready features with support for monitoring, evaluation, and debugging
- Flexible abstraction layers from high-level chains to low-level components
- Seamless integration with the LangChain ecosystem including Deep Agents, LangGraph, and LangSmith
