Decision Matrix

When to Choose Cortex Linux

✅ Choose Cortex Linux if:

  • Data privacy is critical
  • Budget constraints require zero API costs
  • Offline operation needed
  • Low latency required
  • Compliance with strict regulations
  • Air-gapped environments
  • High-volume usage (cost savings)
  • Full system control desired

When to Choose Cloud AI Services

✅ Choose Cloud AI Services if:

  • Maximum accuracy required (larger models)
  • No infrastructure management desired
  • Occasional/low-volume usage
  • Internet connectivity always available
  • Vendor-managed compliance acceptable
  • Budget allows for API costs
  • Rapid scaling needed

Hybrid Approach

Consider using both:

  • Cortex Linux: For sensitive data, high-volume, low-latency needs
  • Cloud AI Services: For complex reasoning requiring larger models
# Hybrid implementation example
from cortex import AI
import openai

cortex_ai = AI()
openai.api_key = "your-key"

def smart_reasoning(query, sensitive=False):
    if sensitive or len(query) < 500:
        # Use Cortex for privacy or simple queries
        return cortex_ai.reason(query)
    else:
        # Use cloud for complex queries
        return openai.ChatCompletion.create(...)

Migration Guide

From Cloud AI to Cortex Linux

Step 1: Install Cortex Linux

See Installation Guide

Step 2: Replace API Calls

Before (OpenAI):

import openai
response = openai.ChatCompletion.create(
    model="gpt-3.5-turbo",
    messages=[{"role": "user", "content": query}]
)

After (Cortex):

from cortex import AI
ai = AI()
response = ai.reason(query)

Step 3: Adjust Expectations

  • Smaller model = slightly lower accuracy on complex tasks
  • On-device = zero API costs
  • Local = better privacy and latency

Step 4: Test and Validate

# Run comparison tests
./scripts/compare_accuracy.sh

# Validate performance
./scripts/benchmark.sh

Conclusion

Cortex Linux provides a compelling alternative to cloud AI services when:

  • Cost is a primary concern (97%+ savings)
  • Privacy is critical (100% on-device)
  • Latency matters (3-8x faster)
  • Compliance requires data sovereignty

Cloud AI services remain better for:

  • Maximum accuracy requirements
  • Occasional usage
  • No infrastructure management
  • Complex reasoning tasks

For most enterprise use cases, Cortex Linux offers superior cost-effectiveness, privacy, and performance with acceptable accuracy trade-offs.
