Rome Wasn't Built in a Day, Understanding Chain of Thought Prompting

Chain of Thought prompting is a method that helps AI solve complex problems step-by-step while guiding it to explain its reasoning process. It is commonly abbreviated as CoT.

CoT not only involves asking AI to find an answer but also requires a step-by-step explanation of how that answer is reached. Often, phrases like step-by-step or in order are included at the end of a prompt to encourage sequential reasoning.

CoT prompting was concretized in a 2022 Google research paper, Chain of Thought Prompting Elicits Reasoning in Large Language Models. According to the paper, CoT prompts improved the accuracy of responses from the GPT-3 model from 38.0% to 54.5%.

This approach is particularly effective in improving outcomes for problems requiring mathematical reasoning by analyzing problem scenarios step-by-step.

CoT prompting includes multiple scenarios within a single prompt similar to Few-Shot Prompting, but it guides each scenario to be reasoned out and resolved step-by-step.

You received $500 as a business travel budget.
You spent $200 on hotel accommodation,
and $100 on transportation.

From the remaining amount, you plan to use $20 per meal.
How many meals can you have at most?

Please calculate it step-by-step.

Copy
Starting Point: You received $500 as a business travel budget.

Total Budget: $500
First Expense Review: You spent $200 on hotel accommodation.

Remaining Budget Calculation: $500 - $200 = $300
Second Expense Review: You spent $100 on transportation.

Remaining Budget Calculation: $300 - $100 = $200
Remaining Amount Check: After spending on hotels and transportation, you have $200 left.

Current Remaining Budget: $200
Unit Cost Confirmation: You plan to use $20 per meal.

Cost per Meal: $20
Maximum Number of Meals Calculation: Calculate the maximum number of meals possible with the remaining money.

Calculation Method: Remaining Amount ÷ Cost per Meal = $200 ÷ $20
Final Calculation and Result:

Calculation Result: $200 ÷ $20 = 10 meals
Maximum Number of Meals: 10 meals

Answer:
You can have a maximum of 10 meals.

CoT excels in solving mathematical problem scenarios, as shown above, but it can also be applied to general situations requiring step-by-step analysis, as seen below.
