Cost Optimization Strategies

1. API Cost Reduction

Techniques:

• Caching: Cache AI responses for identical queries (30-day TTL)
• Batch Processing: Group similar requests (e.g., weekly topic suggestions)
• Haiku for Simple Tasks: Use Claude Haiku for media triage (5x cheaper)
• Rate Limiting: Cap AI requests per user/day
• Human Overrides: Allow admins to skip AI for trivial cases

Savings: 30-50% reduction in API costs

2. Hosting Cost Reduction

Techniques:

• Start Small: Begin with VPS Value, upgrade as needed
• Annual Billing: OVHCloud offers ~20% discount for annual payment
• Resource Optimization: Optimize database queries, enable caching
• Self-Host Everything: Analytics, error tracking, monitoring (no SaaS fees)
• Cloudflare Free Tier: CDN + DDoS protection at no cost

Savings: 20-30% reduction in hosting costs

3. Bandwidth Optimization

Techniques:

• Image Optimization: WebP format, lazy loading
• Compression: Gzip/Brotli for all text assets
• CDN: Offload static assets to Cloudflare
• Minimize Dependencies: No unnecessary JavaScript libraries

Savings: Avoid bandwidth overage fees

Appendix: Cost Calculator

Interactive Budget Calculator (Conceptual)

// Example usage:
const monthlyBudget = calculateMonthlyCost({
  vps: 'essential',        // $30
  apiRequests: 500,        // ~$50
  backups: true,           // $10
  cdn: false,              // $0
  errorTracking: 'free'    // $0
});

console.log(monthlyBudget); // $90

Implementation: Could be added to admin dashboard for real-time cost tracking.
