LangChain’s core offering is an open-source framework that allows developers to build AI agents with as few as 10 lines of code, dramatically lowering the technical barrier to entry[2]. The platform provides pre-packaged building blocks and a unified API, enabling engineers to switch between different large language models (such as those from OpenAI and Anthropic) without rewriting their code[2]. This flexibility is a key selling point in a rapidly evolving AI landscape where model providers frequently update or replace their offerings.
