estimated usage cost

$0.775

1,000 requests × (1,000 uncached input × $0.20 + 500 output × $1.15) / 1,000,000 = $0.775

base rates; no context pricing tiers are published.

estimates use published impossibl api usage rates. configured billing adjustments, funding fees, taxes, and custom workspace rates are excluded and may change the final amount.

image and audio usage, cache creation, and additional tool charges are excluded. reasoning tokens count as billable output, even when they are not visible in the response.
