LangChain Basics #4: Understanding LangChain Chains

Hands-On LangChain for LLMs App Development: Chains

One of the fundamental pillars of LangChain, as implied by its name, is the concept of "chains." These chains typically integrate a large language model (LLM) with a prompt.

Through these chain structures, you have the ability to assemble multiple building blocks, enabling the execution of a series of operations on your text or other data.

This article will delve into the significance of these chains, ranging from basic forms like the Simple Sequential Chain to more sophisticated variations such as the Router Chain, elucidated with practical illustrations.
