What is Chain in LangChain?
In LangChain, a “chain” refers to a sequence of components or steps that are linked together to process input and generate output, especially in the context of working with language models. It is a conceptual framework used to organize and streamline the interaction between different elements involved in handling language tasks.
For developing more complex applications, it’s essential to connect various components and functionalities of LangChain through a “Chain” — linking models together or connecting models with other components.
The concept of interlinking multiple components to form a chain is straightforward yet powerful. It simplifies the implementation of complex applications and makes them more modular. This approach enables the creation of unified, coherent applications, thereby easing debugging, maintenance, and enhancement.
The implementation and use of chains in LangChain are quite straightforward.
- First, LangChain utilizes well-designed interfaces to implement specific functionalities of a chain. For example, the LLM Chain (LLMChain) is capable of receiving…
