Code Generation Performance

# Test prompt: "Create a Python function to calculate fibonacci sequence"

# Ollama Llama 2 70B Result
def fibonacci(n):
    if n <= 1:
        return n
    return fibonacci(n-1) + fibonacci(n-2)

# Commercial AI Results (GPT-4)
def fibonacci(n):
    if n <= 0:
        return 0
    elif n == 1:
        return 1
    
    a, b = 0, 1
    for i in range(2, n + 1):
        a, b = b, a + b
    return b

Winner: Commercial platforms provide more optimized solutions with better edge case handling.

Cost Analysis: The Real Financial Impact

Monthly subscriptions add up quickly, especially for businesses running multiple AI workflows. Here's the true cost breakdown.

Individual Users (Monthly)

• Ollama: $0 (one-time hardware investment)
• ChatGPT Plus: $20
• Claude Pro: $20
• Gemini Advanced: $20
