LangChain is a framework for developing applications powered by LLMs. Its core strength lies in its LangChain Expression Language (LCEL), which allows you to “pipe” components together into a chain. This creates a clear, linear sequence where the output of one step becomes the input for the next. It’s built for workflows that are Directed Acyclic Graphs (DAGs), meaning the process flows in one direction without loops.
