|---|---|
| Scope | Prices paid by businesses for enterprise AI tokens as observed in Ramp's spend data (March 2025). It is not a measurement of the cost of operating a self-hosted serving stack; purchase price, provider cost, and self-hosted cost have different denominators. |
| Caveat | Dated March 2025 observation from Ramp's card and bill-pay spend data; not a self-hosted serving cost. Ramp's 2026 effective token-price index ($1.15/M March peak to $0.68/M on 9 September 2026) is a different series and should not be spliced to this one. |
| As of | 2025-03 |
| Source | Ramp · Ramp AI Index findings: average cost fell from $10 per million tokens to $2.50 as of March 2025. |
