Multi-step prompting

Break down an end goal into series of steps
Model goes through each step to give final output
Multi-step prompts are used for:
- Sequential tasks
- Cognitive tasks

Diagram showing that a multi-step prompt is a prompt that gives the model a series of sequential steps to perform.

Analyzing solution correctness

Checking solution correctness requires multiple steps
Example:
- Python code for calculation functions

Image of a calculator

Analyzing solution correctness

Typical solution to check

calculator = """
def add(a, b):
    return a + b
def subtract(a, b):
    return a - b
def multiply(a, b):
    return a * b
def divide(a, b):
    return a / b
"""

Single-Step Prompt:

prompt = f"""Determine if the code delimited 
by triple backticks is correct or not.
Answer by yes or no.
```{calculator}```"""

print(get_response(prompt))

Yes

Multi-step prompting to analyze solution correctness

Multi-Step Prompt:

prompt = f"""Determine the correctness of the code delimited by triple backticks 
as follows: 
Step 1: Check the code correctness in each function. 
Step 2: Verify if the divide function handles the case when dividing by 0. 
Code: ```{calculator}```"""

print(get_response(prompt))

The code appears to be correct. It defines four functions: add, subtract, multiply, and 
divide. Each function performs the corresponding mathematical operation and returns the
result. However, it does not handle the case when dividing by 0, which can result in a 
ZeroDivisionError.

Multi-step versus few-shot prompt

Steps

Explicitly tell model what to do

Diagram showing how a multi-step prompt breaks down the instruction into a series of steps in the input for the model to go over them one by one.
