# GPT Image 2 Web API

> Use gpt-image-2-web for lower fixed-price text-to-image, one or multiple reference images, three sizes, quality forwarding, and asynchronous tasks.

`gpt-image-2-web` is the lower fixed-price reverse-image route for text-to-image and reference-image generation. The current price is USD 0.03 per request; check the [model marketplace](https://api.yingtu.ai/pricing) before relying on that value.

This is a YingTu model ID in the GPT Image 2 family. OpenAI's [official model page](https://developers.openai.com/api/docs/models/gpt-image-2) publishes the `gpt-image-2` alias and the dated snapshot `gpt-image-2-2026-04-21`; a direct OpenAI migration must change the model value as well as the base URL.

## Where this route fits

Use Web for product mockups, editorial images, social assets, background changes, and queued image jobs when the three documented sizes are sufficient.

The route supports:

* synchronous text-to-image generation;
* synchronous one-source-image editing;
* unified task-ID generation and editing with 1–16 reference images;
* `1024x1024`, `2048x2048`, and `3840x2160` output;
* one Base64 PNG result.

## How `quality` behaves

The route forwards `low`, `medium`, `high`, or `auto`. The selected upstream determines how strongly that value affects the result, so accepted syntax is not a cross-provider quality guarantee.

Choose [`gpt-image-2-vip`](/en/models/image/gpt-image/gpt-image-2-vip/overview) when the application needs the route whose four values have been exercised across the complete documented workflow.

## Connection strategy

Use synchronous Generate or single-image Edit when the caller can wait for a complete response. For asynchronous or multi-image work, submit `/v1/images/tasks` with `action=generate` or `action=edit`, add `Idempotency-Key`, persist `task_id`, and poll with a deadline.
