Definition
In AI application development, a Chain refers to a linear or directed graph structure where multiple components, such as LLM calls, parsers, or external tools, are linked together. Data flows from one step to the next, allowing for modular orchestration of complex workflows. This paradigm enables developers to build sophisticated applications by combining simple, reusable units into a cohesive pipeline, ensuring that the output of one stage serves as the input for the subsequent stage.
Summary
A Chain is a sequence of connected steps or modules that process data sequentially to achieve a complex task.
