Billing conditions
Cached reads, cache writes and storage are different charges. Tool calls, audio and third-party hosting can add separate costs; these text-token prices are not a complete usage bill.
Price history
Initial records are observations, not price cuts. Effective dates remain unknown unless an official source states them. Verification without a price change does not add a history event.
