Towards LangChain 0.1: LangChain-Core and LangChain-Community
Blog post from LangChain
LangChain, initially a side project and Python package, has evolved significantly over the past year, prompting a re-architecture into three distinct packages to enhance developer experience, maintainability, and scalability while remaining backwards compatible. The new structure includes langchain-core, which houses core abstractions and the LangChain Expression Language to facilitate composability, langchain-community for third-party integrations, and langchain for high-level cognitive architecture components. This reorganization aims to stabilize the ecosystem, simplify versioning, and improve integration management. LangChain also supports an expansive ecosystem with tools like LangServe and LangSmith, which aid in deployment and debugging, respectively. This strategic shift encourages further exploration and optimization of use cases in the GenAI space, allowing integration partners to own their frameworks and applications more fully while supporting an ever-growing user base.
