The Frontier basket is flat at $4.64 per 1M tokens across 144 daily points, so the cost of running flagship AI did not move over this window. For developers, that means budget planning is stable right now, with no drift in the blended price to explain away.
This index tracks a fixed Frontier basket using a 3:1 input:output blend, so the clean read here is simple: the market price for this flagship slice of AI held steady from Jun 15, 2026 to Nov 12, 2026. A 0% change from $4.64 means there was no visible cost compression or inflation in the period.
The practical takeaway is that token spend is predictable if your workload maps to this basket. You are not getting a cheaper Frontier baseline over time, but you are also not facing a rising bill from this segment alone.
The Budget basket at $0.74 per 1M tokens shows how wide the gap still is between cheaper models and the Frontier tier. If your product can tolerate lower-end quality or narrower capability, the budget path remains materially cheaper on a per-token basis.
- Frontier is flat at $4.64 per 1M tokens, so recent spend is easy to forecast.
- There is no sign of price relief in the Frontier basket over this window.
- Budget is $0.74 per 1M tokens, which keeps low-cost workloads in a different spend class.
- If your app needs flagship models, plan around a stable but not declining token bill.
