LangChain is a framework for developing applications powered by large language models, simplifying development, productionization, and deployment stages.
LangChain is an open-source framework that assists in creating applications utilizing large language models (LLMs). The framework facilitates development by providing reusable building blocks and components, enabling quicker application creation. For productionization, LangSmith helps inspect, monitor, and evaluate chains, allowing developers to continuously optimize and deploy with confidence. LangServe turns any chain into an API, ensuring seamless integration and deployment. LangChain comprises several libraries, such as langchain-core, langchain-community, and partner packages like langchain-openai and langchain-anthropic. Additional components like langgraph, langserve, and LangSmith further enhance the framework's capabilities.
