Mathematical Methodology & Benchmark Assumptions
1. Mathematical Formulation & Amortization Mechanics
The total cost of ownership (TCO) for foundation model inference diverges significantly between multi-tenant public APIs and dedicated private sovereign clusters. The model implements the following dual-cost formulation:
C_cloud = ((T_in * P_in + T_out * P_out) / 1,000,000) * 12
C_sovereign = C_hw_amortized + C_power_cooling + C_network_egress
Net_Annual_Savings = C_cloud - C_sovereign
Arbitrage_Ratio = (Net_Annual_Savings / C_cloud) * 100%2. Empirical Pricing & Hardware Baselines
- OpenAI GPT-4o: $2.50 per 1M prompt tokens, $10.00 per 1M completion tokens ($4.38/MTok blended at 3:1 input/output ratio).
- Anthropic Claude 3.5 Sonnet: $3.00 per 1M prompt tokens, $15.00 per 1M completion tokens ($6.00/MTok blended at 3:1 input/output ratio).
- Google Gemini 1.5 Pro: $3.50 per 1M prompt tokens, $10.50 per 1M completion tokens ($5.25/MTok blended).
- On-Premise Sovereign Cluster: 8x NVIDIA L40S or 4x H100 SXM5 compute nodes capital cost amortized over 36 months ($1,850/mo), electricity calculated at $0.11/kWh with PUE 1.35, and redundant NVLink switching. Net equivalent cost: $0.27/MTok input and $1.10/MTok output.
3. Data Residency & Legal Non-Financial Dividend
In addition to raw dollar arbitrage, private sovereign clusters eliminate statutory risk under India's DPDP Act 2023, EU GDPR Article 44 cross-border transfer prohibitions, and RBI circular RBI/2023-24/104 regarding confidential banking telemetry retention on external multi-tenant infrastructure.
