Cost example
100 API requests
$0.125
100 requests with 1,000 input and 500 output tokens each calculate to $0.125. Input accounts for $0.025; output accounts for $0.1.
- Input price
- $0.25 / 1M tokensBase tier for each request
- Output price
- $2 / 1M tokensBase tier for each request
The calculation uses documented token prices and no cache discount. It excludes extra tools, tax, reasoning tokens, and further hidden output tokens.
