GPT Image 2 API Pricing: OpenAI’s Listed Costs and How to Estimate Usage

That is the safest source-backed pricing statement. The same snippet does not provide enough context to publish a complete generated-image total or a verified flat per-image quote.^[2]

Is GPT Image 2 priced at a flat cost per image?

Not from the evidence provided here. The OpenAI pricing snippet shows input and cached-input fields for GPT-image-2, but it does not expose a complete per-image calculation in the supplied material.^[2]

That distinction matters if you are writing product documentation, customer-facing pricing notes, or internal cost forecasts. If you quote the two visible fields, cite OpenAI’s pricing page. If you turn those fields into a usage estimate, first confirm the live pricing page’s billable units and the exact API route your application uses.^[1][2]

Where to estimate GPT Image 2 usage pricing

Use OpenAI’s API Pricing page as the pricing source of truth, then match that pricing row to the way your application calls image generation.^[1][2]

A practical workflow:

1. Find the GPT-image-2 row on OpenAI’s pricing page. The visible OpenAI pricing snippet lists $8.00 for inputs and $2.00 for cached inputs.^[2]
2. Confirm the API path. OpenAI’s docs say image generation can run through the image generation endpoint or through the image generation tool in the Responses API.^[12][15]
3. Use the Image API for simple single-prompt jobs. OpenAI’s docs say the Image API is the best choice if you only need to generate or edit a single image from one prompt.^[14]
4. Check model selection in Responses API flows. OpenAI says the Responses API image generation tool uses its own GPT Image model selection, so verify that the selected model is actually gpt-image-2 before applying GPT Image 2 pricing assumptions.^[12]
5. Calculate from the live page’s billable units. The provided evidence supports the visible input and cached-input fields, not a complete flat per-image total.^[1][2]

Endpoint checklist for developers

OpenAI’s image-generation docs say the API can generate and edit images from text prompts using GPT Image or DALL·E models.^[14][15] For GPT Image 2 specifically, the docs identify gpt-image-2 as the latest GPT Image model, and OpenAI also provides a dedicated GPT Image 2 model documentation page.^[12][22]

Safe wording for docs or support

Use wording that separates the verified price fields from the final estimate:

OpenAI’s API Pricing page lists GPT-image-2 with $8.00 for inputs and $2.00 for cached inputs. Final usage estimates should be calculated from OpenAI’s live pricing page after confirming the endpoint, model selection, and billable units used by the application.^[1][2][12]

Bottom line

The fact-checked cost statement is limited: OpenAI’s pricing page lists GPT-image-2 with $8.00 for inputs and $2.00 for cached inputs.^[2] For real usage planning, start with OpenAI’s API Pricing page, then verify whether your product uses the Image API or the Responses API image generation tool before publishing a final estimate.^[1][12][15]
