  • ✓ Implement request batching
  • ✓ Fallback to cheaper models for simple tasks
  • ✓ Use streaming for better UX without cost increase

⚠️ Cost Traps to Avoid

  • ✗ Premium models for simple tasks
  • ✗ Unnecessarily long system prompts
  • ✗ No request deduplication
  • ✗ Ignoring rate limits (error costs)
  • ✗ No usage monitoring or alerts

Budget-Conscious Scaling Path

1

Months 1-3: Pure Free Tier ($0)

Exhaust all free credits and allowances. Build your MVP and validate the concept before spending money.

2

Months 4-6: Minimal Paid ($5-15/month)

Switch to cheapest paid models. Implement caching and optimization to minimize requests.

3

Months 6+: Gradual Quality Increase ($20-50/month)

As revenue grows, gradually upgrade to better models for improved user experience.
