    The above-200K rates applied only with the 1M-context beta. The pricing page lists only input and output prices above 200K tokens and says prompt caching multipliers and the Batch API discount apply on top of long context pricing; those above-200K cache and batch prices are not printed as numbers; they are derived from the multipliers the same page states for this model's long context tier (cache read 0.1x, 5-minute write 1.25x, 1-hour write 2x the long context input price; batch 50% of long context input and output).

Gaps in this history

Above-200K cache and batch prices during the 2026-02-17 to 2026-03-13 beta are derived from the multipliers the pricing page states, not printed as numbers.
