Chains (sequential, router) in Prompt Engineering / GenAI - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a sequential chain in AI workflows?

A sequential chain is a series of steps where the output of one step becomes the input of the next, like passing a message along a line.

beginner

How does a router chain decide which path to take?

A router chain looks at the input and chooses the best path or model to handle it, like a traffic controller directing cars to different roads.

Why use chains in AI model design?

Chains help break complex tasks into smaller steps or routes, making AI easier to manage and more flexible, like following a recipe step-by-step.

intermediate

What is the main difference between sequential and router chains?

Sequential chains run steps one after another in order, while router chains pick one path from many based on the input.

beginner

Give a simple example of a sequential chain in AI.

An example is first cleaning text, then translating it, then summarizing it, where each step uses the previous step's output.

What does a sequential chain do in AI?

A Runs steps one after another using previous outputs

B Randomly selects a model to run

C Runs all models at the same time

D Ignores input and outputs fixed results

Sequential chains process steps in order, passing outputs forward.

How does a router chain choose a path?

A Runs all paths simultaneously

B Always chooses the first path

C Based on input characteristics

D Chooses randomly

Router chains analyze input to pick the best path.

Which chain type is best for step-by-step tasks?

A Router chain

B Sequential chain

C Random chain

D Parallel chain

Sequential chains are designed for ordered steps.

What is a key benefit of using chains in AI?

A Makes AI slower

B Always improves accuracy

C Removes the need for data

D Simplifies complex tasks by breaking them down

Chains help manage complexity by dividing tasks.

In a router chain, what happens if input doesn't match any path?

A The chain picks a default path

B The chain crashes

C The chain ignores the input

D The chain runs all paths

Router chains usually have a default path for unmatched inputs.

Explain how sequential and router chains differ and give an example of when to use each.

Think about a line of tasks versus a traffic controller.

Describe why chains are useful in AI workflows and how they improve task handling.

Consider how recipes or directions help in cooking or traveling.
