Share of input tokens served from cache. Applied only to models with a cache meter.
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.
What this lane charges right now

How much to trust these numbers
Long Context tier, for prompts past the short-context threshold; input and cached input are 2x the short-context rates, output 1.5x. Cut from $2.00/$0.20/$9.00 in the 2026-08-01 Foundry tranche as the short-context Luna row, matching OpenAI's direct long-context rate exactly. A commercial long-context Priority Processing meter arrived in the 2026-09-01 tranche.
