The price of a token API list prices for frontier models, in USD per million tokens — standard tier, text, base context. Each number is verified against the lab’s official pricing page (date shown); the daily series is in the free API . More labs get added as they’re verified — never before.

The dashed rays are constant output÷input ratios — nearly the whole market prices output at 5–6× input. Distance along a ray is price class; distance off it is pricing strategy.

Last snapshot: 2026-08-11 02:51 UTC · List prices, not negotiated rates; cached-input, batch, and long-context tiers vary by lab and are noted where they differ. Same rule as the GPU side: a missing number beats a wrong one.
