Routing and Conditional Chains
Build chains that dynamically pick a path based on input, sending each request to the most appropriate sub-chain for smarter, branching workflows.
Beyond Straight-Line Chains
Sequential chains always run the same steps in order. But real workflows branch: a billing question and a coding question need different handling.
This lesson covers routing chains that choose a path based on the input.
What a Router Does
A router inspects the input, decides which destination chain best fits, and forwards the input there. It is a dispatcher in front of several specialist chains.
input -> router -> { billing_chain | code_chain | general_chain }All lessons in this course
