LangChain
An open-source framework for developing applications powered by large language models (LLMs).
Detailed Definition
LangChain is a popular open-source framework designed to simplify the development of applications powered by large language models (LLMs). It provides a series of modular components, tools, and interfaces that enable developers to easily combine LLMs with external data sources, other computational resources, and memory capabilities to build more complex and capable AI applications, such as personalized chatbots, document Q&A systems, and autonomous AI agents. LangChain supports various LLM providers and includes features for prompt management, output parsing, document loading and splitting, vector storage, and agent orchestration. The framework has become essential for developers building production-ready LLM applications.
