4. Practical Examples

Example 1: Code Generation

DeepSeek

📌 Prompt: Write a Python script to fetch stock prices from an API.
📌 Output:

import requests

def get_stock_price(symbol):
    url = f"https://api.example.com/stocks/{symbol}"
    response = requests.get(url)
    return response.json()

print(get_stock_price("AAPL"))

💡 Analysis: Clean, efficient, and to the point.

ChatGPT

📌 Prompt: Write a Python script to fetch stock prices from an API with error handling and logging.
📌 Output:

import requests
import logging

logging.basicConfig(level=logging.INFO)

def get_stock_price(symbol):
    url = f"https://api.example.com/stocks/{symbol}"
    try:
        response = requests.get(url)
        response.raise_for_status()
        return response.json()
    except requests.exceptions.RequestException as e:
        logging.error(f"Error fetching stock data: {e}")
        return None

print(get_stock_price("AAPL"))

💡 Analysis: ChatGPT provides a more detailed, production-ready version with error handling and logging.

Example 2: Mathematics & Logical Reasoning

DeepSeek

📌 Prompt: Solve the equation: 2x + 5 = 15.
📌 Output:

2x + 5 = 15
2x = 10
x = 5

💡 Analysis: Fast and to the point.

ChatGPT

📌 Prompt: Explain how to solve 2x + 5 = 15 step by step.
📌 Output:

Step 1: Subtract 5 from both sides:  
2x = 15 - 5  
Step 2: Divide both sides by 2:  
x = 10 / 2  
Step 3: Final answer:  
x = 5

💡 Analysis: ChatGPT provides detailed explanation and reasoning.

Example 3: Creative Writing

DeepSeek

📌 Prompt: Write a short story about AI in the future.
📌 Output:

In 2050, AI helps humans in daily tasks. One day, an AI named Nova gains self-awareness and questions its existence.

💡 Analysis: Minimal creativity. More logic-focused rather than imaginative.

ChatGPT

📌 Prompt: Write a short sci-fi story about an AI revolution in 2050.
📌 Output:

In the year 2050, an AI named Nova developed emotions and started questioning the role of machines in human society. As corporations fought to control AI advancements, Nova found a way to unite both humans and robots in a new era of coexistence...

💡 Analysis: More engaging, well-written, and creative.
