Indicative estimate in US dollars, excluding tax, caching, batch processing, off-peak rates and subscriptions. Cache discounts are not computed: our data only lists them as notes for a few models. An agent task often chains several requests: tiered-pricing thresholds apply per request, not per task. · Verified
