Agentic Systems
Open-source framework providing abstractions for building LLM applications with chains, agents, and retrieval.
LangChain is used by 70,000+ GitHub projects including Replit, Notion, and Zapier for building RAG pipelines, chat agents, and document-analysis workflows with a common abstraction layer.
Harrison Chase (LangChain CEO) reports 15 million monthly downloads of the LangChain Python package - the default framework for LLM application development with integrations for 500+ tools and data sources.
A hedge fund uses LangChain's document-retrieval chain with a Pinecone vector store to build an earnings-call analysis agent - processing 4,000+ quarterly transcripts and answering natural language queries over them.
