## 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

- Additional tools/services needed
- Domain/email issues

**Total with Contingency**: **$660 USD** (~$1,090 NZD)

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