Task 1: Give Python code for below flowchart

Pixtral 12B

# Function to determine if one can afford to live alone
def can_afford_to_live_alone(hourly_pay, hours_per_week):
    # Calculate weekly pay
    weekly_pay = hourly_pay * hours_per_week

    # Determine if weekly pay is greater than 400
    if weekly_pay > 400:
        return "can afford to live alone"
    else:
        return "can't afford to live alone"

# Main function to execute the flowchart
def main():
    # Input hourly pay and hours per week
    hourly_pay = float(input("Enter hourly pay: "))
    hours_per_week = float(input("Enter hours per week: "))

    # Determine if one can afford to live alone
    result = can_afford_to_live_alone(hourly_pay, hours_per_week)

    # Output the result
    print(result)

# Execute the main function
if __name__ == "__main__":
    main()

Qwen2-VL-72B

# Start
hourly_pay = float(input("Enter your hourly pay: "))
hours_per_week = float(input("Enter the number of hours you work per week: "))

# Calculate weekly pay
weekly_pay = hourly_pay * hours_per_week

# Check if weekly pay is greater than 400
if weekly_pay > 400:
    print("You can afford to live alone.")
else:
    print("You can't afford to live alone.")

# End

Winner- Pixtral 12B

Pixtral 12B Code Snippet is better because it follows good programming practices by using functions to separate logic and improve readability and maintainability. This modular approach makes the code easier to extend, test, and debug. For simple scripts, the Qwen2-VL-72B snippet might be sufficient, but for more complex scenarios or larger projects, the first snippet’s structure is preferable.

Task 2: Convert the image to CSV format

Pixtral 12B

Qwen2-VL-72B

Winner- Qwen2-VL-72B

Qwen2-VL-72B provided the better output. It correctly formatted the CSV without extra headers, ensuring that the data aligns properly with the columns. This makes it easier to use and analyze the data directly from the CSV file.

Task 3: Tell me the input fields in this image

Pixtral 12B

Qwen2-VL-72B

Winner: Pixtral 12B

Both models identified the input field but Pixtral AI emerged as a winner by providing detailed and comprehensive information about the image and identifying the input fields.

Task 4: Explain this image 

Pixtral 12B

Qwen2-VL-72B

Winner: Pixtral 12B

Both models could identify that the cat was running in the image. But Pixtral gave a more appropriate explanation with completely relatable information.

Performance Rating

Based on the performance, Pixtral emerged as the winner in 3 out of 4 tasks, showcasing its strength in accuracy and detail despite being a smaller model (12B) compared to Qwen2-VL-72B. The overall rating can be summarized as follows:

• Pixtral 12B: Demonstrated strong capability in providing detailed, context-aware, and accurate descriptions, outperforming Qwen2 in most tasks despite its smaller size. Its ability to deliver precise information consistently gives it a higher rating in this comparison.
• Qwen2-VL-72B: Although larger, it struggled with accuracy in key tasks. Its performance was strong in terms of providing general descriptions but lacked the depth and precision of Pixtral.

Overall Rating

• Pixtral 12B: 4.5/5
• Qwen2-VL-72B: 3.5/5

Pixtral’s ability to outperform a much larger model indicates its efficiency and focus on delivering accurate results.

Conclusion

In the rapidly evolving landscape of AI-driven creativity, Pixtral 12B and Qwen2-VL-72B represent two distinct approaches to text-to-image generation, each with its strengths. Through hands-on evaluation, it’s clear that Pixtral 12B, despite being a smaller model, consistently delivers accurate and detailed results, particularly excelling in tasks that prioritize speed and precision. It is an ideal choice for real-time applications, offering a balance between efficiency and output quality. Meanwhile, Qwen2-VL-72B, while powerful and capable of handling more complex and nuanced tasks, falls short in some areas, mainly due to its larger size and need for more advanced hardware.

The comparison between the two models highlights that bigger doesn’t always mean better. Pixtral 12B proves that well-optimized, smaller models can outperform larger ones in certain contexts, especially when speed and accessibility are critical.

Key Takeaways

• Pixtral 12B shines in speed and accuracy, making it suitable for real-time applications and general tasks where quick and efficient results are essential.
