# GPT-Image-2-VIP 이미지 생성

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

> [!NOTE]
>
> **중국 본토 사용자 안내:** 중국 본토 사용자는 `https://toapis.cn` 를 API 엔드포인트(Base URL)로 사용해 주세요. 본 문서의 예시에서 `https://toapis.com` 을 `https://toapis.cn` 로 바꿔 주세요.

* Unified image generation API
* Select the `gpt-image-2-vip` model via the `model` parameter
* 파라미터 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 이미지 API](https://docs.toapis.com/docs/ko/api-reference/uploads/images.md) first to upload images and obtain a URL.

## Authorizations

**Authorization** `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
```

## Body

**model** `string` *required* (default: gpt-image-2-vip)

Image generation model name

Example: `"gpt-image-2-vip"`

**prompt** `string` *required*

Text prompt for image generation

Maximum 32,000 characters for GPT image models

**size** `string` (default: 1:1)

Output image aspect ratio

Preset ratios:

`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`

You may also pass any ratio in `width:height` format, such as `1:3` or `7:4`, subject to the custom-size limits below.

You can pass `auto` to let the upstream provider choose the dimensions, but the final aspect ratio and pixel dimensions are not guaranteed.

**resolution** `string` (default: 1k)

Output resolution tier

Supported values: `1k`, `2k`, `4k`

### Custom Resolutions

In addition to the presets above, pass any ratio in `width:height` format through `size`. The service calculates pixel dimensions from the selected `resolution` tier. The resulting dimensions must meet all of these limits:

* Both sides must be multiples of 16 pixels
* The long edge can be at most 3,840 pixels (4K)
* The aspect ratio can be at most 3:1
* Total pixel count must be between 655,360 and 8,294,400

Examples:

* `size: "1:3"` with `resolution: "2k"` → `1024x3072`
* `size: "7:4"` with `resolution: "1k"` → `1344x768`

```bash theme={null}
curl --request POST \
  --url https://toapis.com/v1/images/generations \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --data '{
    "model": "gpt-image-2-vip",
    "prompt": "A simple red circle on a white background",
    "size": "1:3",
    "resolution": "2k",
    "quality": "medium",
    "n": 1
  }'
```

**quality** `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

**background** `string` (default: auto)

생성 이미지의 배경 스타일

* `auto` — 모델이 자동 결정 (기본값)
* `transparent` — 투명 배경
* `opaque` — 불투명 배경

> [!NOTE]
>
> 투명 배경은 PNG 출력과 함께 사용하는 것이 좋습니다.

**n** `integer` (default: 1)

Number of images to generate

Default: 1

**response\_format** `string` (default: url)

응답 format

The API returns image URLs, so `url` is the recommended value

**reference\_images** `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 이미지 API](https://docs.toapis.com/docs/ko/api-reference/uploads/images.md) to upload local files and get URLs
* Supports single-image and multi-image reference

**image\_urls** `string[]`

Backward-compatible reference image field

ToAPIs automatically normalizes it to `reference_images`

**callback\_url** `string`

ToAPIs 표준 완료 callback입니다. Token HTTPS URL과 secret을 설정하고 같은 origin만 덮어쓸 수 있습니다. [Webhook](https://docs.toapis.com/docs/ko/api-reference/webhooks/task-webhooks.md).

## 응답

**id** `string`

Unique task identifier for status queries

**object** `string`

Object type, always `generation.task`

**model** `string`

모델 name used

**status** `string`

Task status

* `queued`
* `in_progress`
* `completed`
* `failed`

**progress** `integer`

Task progress percentage (0-100)

**created\_at** `integer`

Task creation timestamp (Unix timestamp)
