Pass between **1 and 4** input images. URLs or uploaded files both work. See [Upload input images](/guides/upload-input-images).

  ```ts Mynth SDK theme={"theme":"kanagawa-dragon"}
  import Mynth from "@mynthio/sdk";

  const mynth = new Mynth();

  const task = await mynth.image.generate({
    prompt: "Uncross her arms and place the serum bottle in her right hand, label toward the camera",
    model: "bria/fibo-edit-1.5",
    inputs: ["https://example.com/portrait.jpg", "https://example.com/product.png"],
    size: "auto",
  });

  console.log(task.urls);
  ```

  ```bash REST API theme={"theme":"kanagawa-dragon"}
  curl https://api.mynth.io/image/generate \
    -X POST \
    -H "Authorization: Bearer $MYNTH_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "prompt": "Uncross her arms and place the serum bottle in her right hand, label toward the camera",
      "model": "bria/fibo-edit-1.5",
      "inputs": [
        {
          "type": "image",
          "source": { "type": "url", "url": "https://example.com/portrait.jpg" }
        },
        {
          "type": "image",
          "source": { "type": "url", "url": "https://example.com/product.png" }
        }
      ],
      "size": "auto"
    }'
  ```

## Auto size

This model supports **native auto size**. Left unset, output keeps the first reference image's ratio.

```ts theme={"theme":"kanagawa-dragon"}
size: "auto";
```

See [Control size](/guides/control-size).
