Cognitive Scaffolding: Simply as people use shorthand to trace their concepts, CoD externalizes vital
ideas whereas avoiding the verbosity that sometimes burdens conventional reasoning fashions. The purpose is to keep up the integrity of the reasoning pathway with out overloading the mannequin with extreme tokens.

Instance of CoD

Downside: Jason had 20 lollipops. He gave Denny some. Now he has 12 left. What number of did Jason give to Denny?  

Response [CoD] : 20–12 = 8 → Remaining Reply: 8.

As we are able to see above the response for the issue had very concise symbolic reasoning steps just like what we do after we are doing downside fixing.

Comparability Between totally different Prompting Methods

Totally different prompting methods improve LLM reasoning in distinctive methods, from step-by-step logic to exterior information integration and structured thought processes.

Customary Prompting

In customary prompting, the LLM generates a direct reply to a question with out exhibiting the intermediate reasoning steps. It offers the ultimate output with out revealing the thought course of behind it.

Though this method is environment friendly by way of token utilization, it lacks transparency. With out perception into how the mannequin reached its conclusion, verifying correctness or figuring out reasoning errors turns into
difficult, significantly for advanced issues that require step-by-step reasoning.

Chain of Thought(CoT) Prompting

With CoT prompting, the mannequin gives an in-depth clarification of its reasoning course of.

This response is thorough and clear, outlining each step of the reasoning course of. Nonetheless, it’s overly detailed, together with redundant info that doesn’t contribute computationally. This extra verbosity drastically will increase token utilization, leading to increased latency and value.

Chain of Draft (CoD) Prompting

With CoD prompting, the mannequin focuses completely on the important reasoning steps, offering solely essentially the most vital info. This method eliminates pointless particulars, guaranteeing effectivity whereas sustaining accuracy.

Benefits of Chain of Draft (CoD) Prompting

Code Implementation of CoD

Now we are going to see how we are able to implement the Chain of Draft prompting utilizing totally different LLMs and strategies.

Strategies to Implement CoD

We are able to implement Chain of Draft in numerous methods allow us to g by means of them:

• Utilizing Immediate Instruction: To implement Chain of Draft (CoD) prompting, instruct the mannequin with the next immediate: “Suppose step by step, however solely hold a minimal draft for every considering step, with 5 phrases at most.” This guides the mannequin to generate concise, important reasoning for every step. As soon as the reasoning steps are full, ask the mannequin to return the ultimate reply after a separator (####). This ensures minimal token utilization whereas sustaining readability and accuracy.
• Utilizing One shot or Few shot instance: We are able to additionally make it extra strong by including some zero or few pictures examples in our immediate to allow LLM to provide a constant response utilizing these examples and generate intermediate steps in brief drafts.

We’ll now implement this in code utilizing two totally different LLM Gemini and Groq API. Gr

Implementation utilizing Gemini

Allow us to now implement these prompting methods utilizing Gemini to boost reasoning, decision-making, and problem-solving capabilities.

Step 1: Generate Gemini API Key

For Gemini API Key go to Gemini Website Click on on get an API Key  button as proven under in pic. You may be
redirected Google AI Studio the place you will have to make use of your google account login after which discover your API Key generated.

Step 2: Set up Libraries

We principally want to put in google genai library.

pip set up google-genai

Step 3: Import Packages and Setup API Key

We import related packages and add API key as a setting variable.

import base64
import os
from google import genai
from google.genai import sorts

os.environ["GEMINI_API_KEY"] = "Your Gemini API Key"

Step 4: Create Generate Operate

Now we outline the generate perform and configure mannequin, contents and generate_content_config .

Notice in generate_content_config  we cross system instruction as ” Suppose step-by-step, however solely hold a minimal draft for every considering step, with 5 phrases at most. Return the reply on the finish of the response after a separator ####.”

def generate_gemini(instance,query):
    shopper = genai.Shopper(
        api_key=os.environ.get("GEMINI_API_KEY"),
    )

    mannequin = "gemini-2.0-flash"
    contents = [
        types.Content(
            role="user",
            parts=[
                types.Part.from_text(text=example),
                types.Part.from_text(text=question),
            ],
        ),
    ]
    generate_content_config = sorts.GenerateContentConfig(
        temperature=1,
        top_p=0.95,
        top_k=40,
        max_output_tokens=8192,
        response_mime_type="textual content/plain",
        system_instruction=[
            types.Part.from_text(text="""Think step by step, but only keep a minimum draft for each thinking step, with 5 words at most. Return the answer at the end of the response after a separator ####."""),
        ],
    )

# Now cross the parameters to generate_content_stream perform
    for chunk in shopper.fashions.generate_content_stream(
        mannequin=mannequin,
        contents=contents,
        config=generate_content_config,
    ):
        print(chunk.textual content, finish="")

Step 5: Execute the Code 

Now we are able to execute the code utilizing two strategies one passing solely system instruction immediate and query instantly. One other is by passing one-shot instance in immediate together with query and system instruction.

if __name__ == "__main__":
    instance = """"""
    query ="""Q: Anita purchased 3 apples and 4 oranges. Every apple prices $1.20 and every orange prices $0.80. How a lot did she spend in complete?
A:"""
    generate_gemini(instance,query)

Response for Zero-shot CoD immediate from Gemini:

Apples price: 3 * $1.20
Oranges price: 4 * $0.80
Whole: sum of each
#### $6.80

if __name__ == "__main__":
    instance = """Q: Jason had 20 lollipops. He gave Denny some lollipops. Now Jason has 12 lollipops. What number of lollipops did Jason give to Denny?
A: 20 - x = 12; x = 8. #### 8"""
    query ="""Q: Anita purchased 3 apples and 4 oranges. Every apple prices $1.20 and every orange prices $0.80. How a lot did she spend in complete?
A:"""
    generate_gemini(instance,query)

Output

Apple price: 3 * 1.20 
Orange price: 4 * 0.80 
Whole: apple + orange 
Whole price: 3.60 +3.20
Whole: 6.80
#### 6.80

Implementation utilizing Groq

Now we are going to use  Groq API which makes use of Llamaa mannequin inside it to display CoD prompting approach.

Step 1: Generate Groq API Key

Much like Gemini we have to first create an account in groq wwe can do it by logging in by means of one in all google account (gmail) on this website. As soon as logged in click on on “Create an API Key”  button and provides a reputation for our api key and duplicate the generated api key because it is not going to be displayed once more.

Step 2: Set up Libraries

We principally want to put in groq library.

!pip set up groq --quiet

Step 3: Import Packages and Setup API Key

We import related packages and add API key as a setting variable.

from groq import Groq

# configure the LM, and keep in mind to export your API key, please set any one of many key
os.environ['GROQ_API_KEY'] = "Your Groq API Key"

Step 4: Create Generate Operate

Now we create generate_groq perform by passing instance and query. We additionally add system immediate “Suppose step-by-step, however solely hold a minimal draft for every considering step, with 5 phrases at most. Return the reply on the finish of the response after a separator ####.””

def generate_groq(instance,query):

  shopper = Groq()
  completion = shopper.chat.completions.create(
      mannequin="llama-3.3-70b-versatile",
      messages=[
          {
              "role": "system",
              "content": "Think step by step, but only keep a minimum draft for each thinking step, with 5 words at most. Return the answer at the end of the response after a separator ####."
          },
          {
              "role": "user",
              "content": example+"n"+question
          },
      ],
      temperature=1,
      max_completion_tokens=1024,
      top_p=1,
      stream=True,
      cease=None,
  )

  for chunk in completion:
      print(chunk.decisions[0].delta.content material or "", finish="")

Step 5: Execute the Code 

Now we are able to execute the code utilizing two strategies one passing solely system instruction immediate and query instantly. One other is by passing one-shot instance in immediate together with query and system instruction. Let’s see the output for Groq Llama fashions

#One shot 
if __name__ == "__main__":
    instance = """Q: Jason had 20 lollipops. He gave Denny some lollipops. Now Jason has 12 lollipops. What number of lollipops did Jason give to Denny?
A: 20 - x = 12; x = 8. #### 8"""
    query ="""Q: Anita purchased 3 apples and 4 oranges. Every apple prices $1.20 and every orange prices $0.80. How a lot did she spend in complete?
A:"""
    generate_groq(instance,query)

Output

Apples price $1.20 * 3
Oranges price $0.80 * 4 
Add each prices collectively 
Whole price is $3.60 + $3.20 
Equals $6.80
#### $6.8

#zero shot
if __name__ == "__main__":
    instance = """"""
    query ="""Q: Anita purchased 3 apples and 4 oranges. Every apple prices $1.20 and every orange prices $0.80. How a lot did she spend in complete?
A:"""
    generate_groq(instance,query)

Output

Calculate apple price. 
Calculate orange price.
Add each prices.
#### $7.20

As we are able to see for zero shot the reply just isn’t coming appropriate for llama mannequin in contrast to gemini mannequin we are going to attempt to tweak and add extra phrases in our query immediate to reach at appropriate reply.

We add this line additional to our Query at finish “Confirm the reply is appropriate with steps”

 #tweaked Zero shot
if __name__ == "__main__":
    instance = """"""
    query ="""Q: Anita purchased 3 apples and 4 oranges. Every apple prices $1.20 and every orange prices $0.80. How a lot did she spend in complete?Confirm the reply is appropriate with steps
A:"""
    generate_groq(instance,query)

Output

Calculate apple price 3*1.20
Equal 3.60
Calculate orange price 4 * 0.80 
Equal 3.20
Add prices collectively 3.603.20
Equal 6.80
#### 6.80

Limitations of CoD

Allow us to now look into the limitation of CoD under:

• Much less Transparency :  As in comparison with different prompting methods equivalent to CoT, CoD has much less transparency because it doesn’t clearly present every verbose steps which will help in debugging and understanding the circulate.
• Elevated chance of errors in intricate reasoning: Sure issues demand thorough intermediate steps to keep up logical accuracy, which CoD could overlook.
• CoD’s Dependency on Examples: As we noticed above for smaller fashions the efficiency drops in zero shot circumstances. It struggles in zero-shot situations, exhibiting a major drop in accuracy with out instance prompts. That is probably as a result of absence of CoD-style reasoning patterns in coaching knowledge, making it more durable for fashions to know the method with out steerage.

Conclusion
