Time

Service tier

Rows with a rate that changes by time of day, promo window or service tier are priced for this scenario instead of their flat listed rate; a brand-colored label under the model name names which one applies. Context size for band-priced rows uses the input-token count below.

Picking a specific hour also previews time-of-day rates that are scheduled but have not started billing yet; those rows are labelled · preview with their start instant. Now only ever shows rates that are billable at this moment.

How much to trust these numbers

InputofficialCached inputofficialOutputofficial

Prompts up to 272K input tokens. Separate cache-write fees are not included.

Verified 2026-11-05 against https://developers.openai.com/api/docs/models/gpt-6.1-terra and https://developers.openai.com/api/docs/pricing. Above 272K prompt tokens, input/cache rates double and output is 1.5x. Batch/Flex are half Standard; Fast is 2x. Cache writes are separate.
