* **Knowledge-rich visuals** — Create diagrams, formulas, educational illustrations, and dense information graphics.

## Text-to-image

```bash cURL theme={null}
curl https://www.anyfast.ai/v1/images/generations \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "seedream-5-0-lite-260128",
    "prompt": "A clean editorial poster explaining the water cycle, accurate labels, clear hierarchy, blue and green palette",
    "size": "2K",
    "output_format": "png",
    "response_format": "url",
    "watermark": false
  }'
```

## Batch image output

Set `sequential_image_generation` to `auto` and use `max_images` to cap the number of images.

```json theme={null}
{
  "model": "seedream-5-0-lite-260128",
  "prompt": "Generate four coherent cinematic storyboard frames showing an astronaut repairing a spacecraft, encountering a meteor shower, escaping the impact, and returning safely",
  "size": "2K",
  "sequential_image_generation": "auto",
  "sequential_image_generation_options": {
    "max_images": 4
  },
  "output_format": "png",
  "response_format": "url",
  "watermark": false
}
```
