# GPT Image 2.5 Sunburst Text to Image API

> GPT Image 2.5 Sunburst chuyển văn bản thành ảnh với chất lượng xhigh/max, tối đa 10 ảnh và kiểm soát nén

Tạo hình ảnh từ lời nhắc dài tối đa 32000 ký tự. Chất lượng gồm auto, low, medium, high, xhigh và max; mức cao hơn tăng chi tiết và độ trễ. `num_images` lên tới 10, còn `output_compression` từ 0 đến 100 áp dụng cho jpeg và webp. Kích thước dùng giá trị đặt sẵn, auto hoặc kích thước cụ thể.

- Model id: `openai/gpt-image-2.5/sunburst/text-to-image`
- Made by: OpenAI

- Output: image
- Estimated price per run: $0.054 / image (cheapest run $0.054 (54 API credits))
- Run: `POST https://api.doitong.ru/v1/run/openai/gpt-image-2.5/sunburst/text-to-image`
- Quote: `POST https://api.doitong.ru/v1/quote/openai/gpt-image-2.5/sunburst/text-to-image`
- Docs page: https://doitong.com/vi/developers/models/openai/gpt-image-2.5/sunburst/text-to-image

## Pricing

Price: **$0.054 / image**. Estimated from the typical cost of one run, per output (`num_images`). The quote is exactly what the run charges.

The full example input below costs $0.054 = 54 API credits (1 image × 54 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.ru/v1/quote/openai/gpt-image-2.5/sunburst/text-to-image` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  | 1 – 32000 characters | Lời nhắc được dùng để tạo sinh hình ảnh. |
| `image_size` |  | object {width, height} \| enum (string) | no | `landscape_4_3` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9`, `auto` | Kích thước đầu ra chấp nhận tên preset, đối tượng {width, height} hoặc 'auto' để mô hình chọn kích thước tốt nhất. Mọi kích thước cụ thể phải có các chiều chia hết cho 16, cạnh không dài hơn 3840px, tỷ lệ khung hình tối đa 3:1 và tổng số pixel từ 655,360–8,294,400. |
| `background` |  | enum (string) | no | `auto` | `auto`, `transparent`, `opaque` | Nền của hình ảnh kết quả. |
| `quality` |  | enum (string) | no | `high` | `auto`, `low`, `medium`, `high`, `xhigh`, `max` | Lựa chọn chất lượng hình ảnh, với 'auto' ủy quyền quyết định cho mô hình. Cài đặt cao hơn cho nhiều chi tiết hơn nhưng có độ trễ dài hơn và mức sử dụng token lớn hơn. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 10 | Số hình ảnh cần tạo. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Định dạng tệp của các hình ảnh đầu ra. |
| `output_compression` |  | integer \| null | no |  | 0 – 100 | Cài đặt nén chỉ khả dụng cho 'jpeg' hoặc 'webp' trong output_format; phạm vi cho phép là 0–100. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Có thể nới lỏng việc kiểm duyệt bằng cách đặt thành false, nếu người gọi được cấp quyền. |

## Example input

Required parameters only:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.ru/v1/run/openai/gpt-image-2.5/sunburst/text-to-image?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/openai/gpt-image-2.5/sunburst/text-to-image?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.ru/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/openai/gpt-image-2.5/sunburst/text-to-image", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.ru/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "openai/gpt-image-2.5/sunburst/text-to-image",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
