Batch halves every rate for jobs that can wait in a queue. Priority has no per-image row on Google's page, so its figures are computed from the $216 per 1M image rate. Flex appears on the pricing page at the Batch price, but Google's Flex documentation lists no image model, so it is left out.

Billed on top of the image (optional)

Pro always thinks before it renders, billed at the text output rate. Our 1K tests reported 122 to 252 tokens per image.

Each input image counts as 560 input tokens, about $0.0011 on Standard.

How this is calculated

Cost per image = image output tokens × the image output rate ÷ 1,000,000, plus the tokens of each add-on × its own rate. Cost per 1,000 images and the monthly total multiply that figure, and nothing is rounded before the last step.

  • Google counts a 1K or 2K image as 1,120 output tokens and a 4K image as 2,000. The calculator multiplies that by the image rate, so 1K and 2K show $0.1344 where Google's page prints the rounded $0.134.
  • Rates and token counts are from Google's Gemini API pricing page for gemini-3-pro-image as read on October 29, 2026. Vertex AI lists the same image rates on its global endpoint.
  • The thinking presets come from our own 1K test of October 8, 2026: nine prompts, one draw each.
