# Hidream O1 Image · Dev API

> guidance가 기본적으로 꺼져 있고 선택적 참조 이미지를 지원하는 28단계 증류 HiDream 텍스트-이미지 변형

dev 버전은 28단계로 증류되었으므로 `num_inference_steps`는 최대 28이고 `guidance_scale`의 기본값은 0입니다. `prompt`와 편집 또는 개인화를 위한 선택적 `reference_image_urls`를 계속 지원합니다. 출력 크기는 약 2048x2048까지이며 호출당 png, jpeg 또는 webp 형식의 이미지 1~4개를 생성합니다.

- Model id: `hidream-o1-image/dev`
- Made by: HiDream
- Category: Text to Image
- Output: image
- Price: $0.005 / megapixel (cheapest run $0.005 (5 API credits))
- Run: `POST https://api.doitong.com/v1/run/hidream-o1-image/dev`
- Quote: `POST https://api.doitong.com/v1/quote/hidream-o1-image/dev`
- Docs page: https://doitong.com/ko/developers/models/hidream-o1-image/dev

## Pricing

Price: **$0.005 / megapixel**. Billed per megapixel of output (width × height of every image). Each image is rounded up to a whole megapixel.

The full example input below costs $0.005 = 5 API credits (1 MP × 5 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.com/v1/quote/hidream-o1-image/dev` 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 characters | 이미지 생성 또는 편집, 혹은 주제 기반 개인화에 사용할 텍스트 지침입니다. |
| `reference_image_urls` | `images` | array of image URL | no | `[]` |  | 편집용 참조 이미지(이미지 1개) 또는 주제 기반 개인화용 이미지(여러 개)입니다. 텍스트-이미지 생성에서는 생략합니다. |
| `image_size` |  | object {width, height} \| enum (string) | no | `{"height":1024,"width":1024}` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | 출력 크기입니다. 약 2048 × 2048 픽셀을 상한으로 하며, 요청한 각 크기는 가장 가까운 32의 배수로 줄어듭니다. |
| `num_inference_steps` |  | integer | no | `28` | 1 – 28 | 노이즈 제거 반복 횟수입니다. 28단계는 dev 모델의 증류 목표에 해당합니다. |
| `guidance_scale` |  | number | no | `0` | 0 – 20 | 분류기 없는 가이던스 스케일입니다. dev 모델의 기본값은 0.0입니다. |
| `seed` |  | integer \| null | no |  |  | 생성 결과를 재현할 수 있게 하는 무작위 시드입니다. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | 생성할 이미지 수입니다. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | 결과 이미지의 파일 형식입니다. |
| `enable_safety_checker` |  | boolean | no | `true` |  | 생성된 이미지에 안전성 검사를 수행할지 제어합니다. |
| `keep_original_aspect` |  | boolean | no | `false` |  | 단일 참조 생성의 종횡비 유지입니다. 이미지를 정확히 1개 제공한 경우에만 출력이 해당 참조 이미지의 비율과 일치합니다. |

File parameters (`images`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## 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.com/v1/run/hidream-o1-image/dev?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.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/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/hidream-o1-image/dev?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.com/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/hidream-o1-image/dev", 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.com/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": "hidream-o1-image/dev",
      "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.
