ai-infra-cost-estimator 1.0.1

Estimate real-world AI + cloud infrastructure costs for LLM applications

🚀 AI Infra Cost Estimator

Estimate real-world AI + cloud costs before scaling breaks you.

---

🎯 Problem

Most AI startups underestimate costs because LLM usage, concurrency, and infrastructure scaling are tightly coupled.

A small growth in requests can cause non-linear cost jumps that catch founders off guard.

This tool estimates:

• 💰 LLM API costs (tokens, caching impact)
• 🖥️ Infrastructure costs (compute, pods, scaling)
• 📈 Scaling thresholds (when costs jump)
• 💡 Optimization recommendations

Before you deploy.

---

✨ Features

• Multi-model support: OpenAI, Anthropic, Google, Meta, Mistral
• Infrastructure estimation: Pod/container scaling calculations
• Caching analysis: See how caching affects your costs
• Scaling breakpoints: Know when you'll need more resources
• Cost projections: See costs at 1.5x, 2x, 3x, 5x growth
• Optimization recommendations: Actionable cost-saving suggestions
• Multiple output formats: Markdown reports & JSON for automation

📊 Example Output

### Monthly Cost Summary

LLM Cost:     $1,820
Infra Cost:   $640
────────────────────────────
Total:        $2,460

Cost per Request: $0.0082
Yearly Estimate:  $29,520

### Scaling Alerts
- At 18,000 req/day → scale to 2 pods
- At 45,000 req/day → cost doubles to $4,920/month

### Recommendations
1. 🟠 Improve cache hit ratio to 40%
   Potential Savings: $520/month
   
2. 🟡 Consider switching to gpt-3.5-turbo
   Potential Savings: $890/month

🧮 How It Works

LLM Cost Calculation

effective_requests = requests_per_day × (1 - cache_hit_ratio)
daily_tokens = effective_requests × (input_tokens + output_tokens)
monthly_cost = (daily_tokens / 1000) × price_per_1k × 30

Infrastructure Calculation

requests_per_second = requests_per_day / 86400
required_concurrency = rps × avg_latency_seconds × overhead_multiplier
required_pods = ceil(required_concurrency / concurrency_limit)
monthly_cost = pods × cost_per_hour × 720

Scaling Breakpoints

The analyzer finds:

• When you need to add pods
• When costs double
• Impact of cache improvements
• Cheaper model alternatives

# Calculate LLM costs
llm_calc = LLMCostCalculator()
llm_result = llm_calc.calculate(
    requests_per_day=10000,
    avg_input_tokens=800,
    avg_output_tokens=400,
    model="gpt-4o-mini",
    cache_hit_ratio=0.2
)

print(f"Monthly LLM Cost: ${llm_result.monthly_total_cost:.2f}")

# Calculate infrastructure costs
infra_calc = InfraCostCalculator()
infra_result = infra_calc.calculate(
    requests_per_day=10000,
    avg_latency_ms=500,
    concurrency_limit=50,
    region="us-east-1"
)

print(f"Monthly Infra Cost: ${infra_result.total_monthly_cost:.2f}")

# Get scaling analysis
analyzer = ScalingAnalyzer()
analysis = analyzer.analyze(
    requests_per_day=10000,
    avg_input_tokens=800,
    avg_output_tokens=400,
    model="gpt-4o-mini",
    cache_hit_ratio=0.2
)

for alert in analysis.scaling_alerts:

for rec in analysis.recommendations[:3]:
    print(f"💡 {rec.title}: Save ${rec.potential_savings:.2f}/month")

🛣️ Roadmap

• v1.1: GPU cost estimation for self-hosted models
• v1.2: Multi-region deployment cost comparison
• v1.3: API endpoint for integration
• v2.0: Real-time cloud integration (AWS, GCP, Azure)

---

📝 Assumptions

These estimates are based on:

• Stateless inference workloads
• HTTP-based serving
• Average token sizes (actual may vary)
• Public API pricing (enterprise pricing may differ)
• No model fine-tuning costs

Clear assumptions = trust.
