Token pricing

MeterUSD / 1M tokensCredits / 1M tokens
Input (text and reference images)$1.50150
Text output and thinking$7.50750
Image output$30.003000

Google Standard token rates; 1 USD = 100 credits. Reference images are charged as input tokens, with no flat per-reference fee. This endpoint settles token usage only; search switches do not add a fixed fee.

Submission precharges only the image portion: 3.36 / 5.04 / 11.34 credits for 1K / 2K / 4K. Completion adjusts the charge to the token total, refunding or collecting the difference. Final charges round up to 0.01 credit; account discounts apply separately.
