LangChain

LangChain is dedicated to empowering developers who are navigating the complexities of building with large language models (LLMs). Many developers and companies face significant hurdles when trying to move beyond simple API calls to create truly dynamic, production-ready AI applications. The challenges often lie in connecting LLMs to proprietary data sources, enabling them to interact with other tools, and managing the state of conversations, all while ensuring the final application is reliable and scalable. Customers need a streamlined way to build, debug, and deploy these sophisticated applications without getting bogged down in boilerplate code and complex integrations.

To address these challenges, LangChain provides a comprehensive open-source framework and a suite of tools designed to simplify the entire AI engineering lifecycle. For developers struggling to make their LLMs context-aware, our framework offers robust components for retrieval augmented generation (RAG), allowing applications to ground their responses in specific, up-to-date information. We understand that building intelligent agents that can reason and take action is a critical goal for our users. That's why we developed LangGraph, a library for creating stateful, multi-actor applications. Furthermore, with LangSmith, we provide essential observability, tracing, and evaluation capabilities, giving developers the visibility they need to debug issues, monitor performance, and confidently ship reliable products. From startups to global enterprises, our customers choose LangChain to transform their innovative ideas into powerful, domain-specific copilots, efficient customer support bots, and intelligent enterprise solutions.
