Financial Decision Matrix for AI Infrastructure§
As enterprise AI adoption matures, chief technology officers face a major financial decision: Should we continue paying per-token managed API pricing, or invest in self-hosted GPU infrastructure running open-weights models?
In this economic analysis, we evaluate the Total Cost of Ownership (TCO) across 3 operational scales over a 12-month period.

12-Month Total Cost of Ownership (TCO) Comparison§
| Monthly Token Volume | Managed API (Proprietary) | Self-Hosted GPU Cluster | TCO Winner |
|---|---|---|---|
| Small (10M Tokens/mo) | $1,800 / year | $14,400 / year | Managed API (8x cheaper) |
| Medium (100M Tokens/mo) | $18,000 / year | $21,600 / year | Managed API (Slight edge) |
| Enterprise (1B Tokens/mo) | $180,000 / year | $54,000 / year | Self-Hosted (70% savings) |

Strategic Guidance§
Start with managed APIs during product validation. Transition to self-hosted open-weights models once monthly token throughput reliably exceeds 300 million tokens.
