Time

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

Standard long-context rate for prompts above 272K input tokens. Batch and Flex are half price; Fast mode is 2x and Ultrafast is 6x.

OpenAI's official GPT-6.1 Sol model page and API pricing page, captured 2026-09-30: prompts above 272K input tokens use $4/M input, $0.20/M cached input, and $15/M output, with a 1,050,000-token context and 128,000 max output. Cache writes are billed separately and are outside this schema.
