Pricing
Published prices
Prices apply to the stated unit. Resolution, output length, and provider can change the cost.
Cost example
100 API requests
$0.2225
100 requests with 1,000 input and 500 output tokens each calculate to $0.2225. Input accounts for $0.075; output accounts for $0.1475.
- Input price
- $0.75 / 1M tokensBase tier for each request
- Output price
- $2.95 / 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.
