4 

5Estimate the input tokens and cost of sending an image to an OpenAI vision model. Select a model, enter your image dimensions, and choose a detail level.

6 

7For GPT Image generation and editing costs, use the [image generation calculator](https://developers.openai.com/api/docs/guides/image-generation#calculating-costs).

8 

9## Use the calculator

10 

111. Select the vision model you plan to use.

122. Enter the original image width and height in pixels. The calculator applies the model's resizing rules.

133. Select an image detail level supported by the model.

144. Read the image input tokens and estimated cost. Expand **Calculation details** to see the resized dimensions and token calculation.

15 

16## Understand the estimate

17 

18The estimate covers one image at standard input rates. It excludes other prompt tokens, model output, caching, long-context pricing, and data-residency adjustments. Billing can differ by one token due to rounding.

19 

20For the resizing and tokenization rules, see [image input cost calculations](https://developers.openai.com/api/docs/guides/images-vision#calculating-costs). For current model rates and other charges, see [API pricing](https://developers.openai.com/api/docs/pricing).

1004The following table covers the general-purpose vision models available in the [image input cost calculator](#image-input-cost-calculator). Other models and specialized variants can use different limits. All resizing preserves aspect ratio without enlarging smaller images.1004The following table covers the general-purpose vision models available in the [image input cost calculator](https://developers.openai.com/api/docs/guides/image-cost-calculator).

1092Vision models convert image inputs into billable input tokens. The calculator and patch/tile rules in this section cover vision-model inputs, not GPT Image generation or editing. See [GPT Image model inputs](#gpt-image-model-inputs) for that separate pricing.1092Vision models convert image inputs into billable input tokens.

1094Image tokens also count toward your [tokens per minute (TPM) limits](https://developers.openai.com/api/docs/guides/rate-limits). The calculator estimates one image at standard input rates; it does not include the rest of your prompt or model output.1094Image tokens also count toward your [tokens per minute (TPM) limits](https://developers.openai.com/api/docs/guides/rate-limits).
