# GPT-Image-2-VIP Image Generation

> Generate images with gpt-image-2-vip. Parameters are the same as gpt-image-2, but all standard aspect ratios are supported.

* Unified image generation API
* Select the `gpt-image-2-vip` model via the `model` parameter
* Parameters are the same as `gpt-image-2`
* Supports text-to-image, single-reference, and multi-reference image generation
* Async task management with task ID based result lookup

<Warning>
  **Important Change**: For better performance and cost control, base64 image data is no longer supported in `image_urls` or `reference_images`. Please use the [Upload Image API](/docs/en/api-reference/uploads/images) first to upload images and obtain a URL.
</Warning>

## Authorizations

<ParamField header="Authorization" type="string" required>
  All endpoints require Bearer Token authentication

  Get your API Key from the [API Key Management Page](https://toapis.com/console/token)

  Add to request header:

  ```
  Authorization: Bearer YOUR_API_KEY
  ```
</ParamField>

## Body

<ParamField body="model" type="string" default="gpt-image-2-vip" required>
  Image generation model name

  Example: `"gpt-image-2-vip"`
</ParamField>

<ParamField body="prompt" type="string" required>
  Text prompt for image generation

  Maximum 32,000 characters for GPT image models
</ParamField>

<ParamField body="size" type="string" default="1:1">
  Output image aspect ratio

  The following ratios are currently supported:

  `1:1`, `3:2`, `2:3`, `4:3`, `3:4`, `5:4`, `4:5`, `16:9`, `9:16`, `2:1`, `1:2`, `21:9`, `9:21`

  `auto` is not supported at the moment.
</ParamField>

<ParamField body="resolution" type="string" default="1k">
  Output resolution tier

  Supported values: `1k`, `2k`, `4k`
</ParamField>

<ParamField body="quality" type="string" default="medium">
  Image quality

  * `low` — fast and economical, suitable for drafts/previews
  * `medium` — balanced speed and quality
  * `high` — maximum detail, suitable for final outputs
</ParamField>

<ParamField body="n" type="integer" default={1}>
  Number of images to generate

  Default: 1
</ParamField>

<ParamField body="response_format" type="string" default="url">
  Response format

  The API returns image URLs, so `url` is the recommended value
</ParamField>

<ParamField body="reference_images" type="string[]">
  Reference image URLs for image-to-image generation

  **⚠️ URL format only (base64 no longer supported)**

  * Publicly accessible URLs (`http://` or `https://`)
  * You can use the [Upload Image API](/docs/en/api-reference/uploads/images) to upload local files and get URLs
  * Supports single-image and multi-image reference
</ParamField>

<ParamField body="image_urls" type="string[]">
  Backward-compatible reference image field

  ToAPIs automatically normalizes it to `reference_images`
</ParamField>

## Response

<ResponseField name="id" type="string">
  Unique task identifier for status queries
</ResponseField>

<ResponseField name="object" type="string">
  Object type, always `generation.task`
</ResponseField>

<ResponseField name="model" type="string">
  Model name used
</ResponseField>

<ResponseField name="status" type="string">
  Task status

  * `queued`
  * `in_progress`
  * `completed`
  * `failed`
</ResponseField>

<ResponseField name="progress" type="integer">
  Task progress percentage (0-100)
</ResponseField>

<ResponseField name="created_at" type="integer">
  Task creation timestamp (Unix timestamp)
</ResponseField>
