## Model Overview

A new Flux model optimized for maximum image quality.

<table data-full-width="true"><thead><tr><th width="279.60009765625">Model</th><th width="593">Properties of Generated Images</th></tr></thead><tbody><tr><td><code>flux/kontext-max/text-to-image</code></td><td>Format: <strong>JPEG, PNG</strong><br>Image size can't be set directly — only a preset aspect ratio can be chosen.<br>Default aspect ratio and size: <strong>1:1</strong>, <strong>1024</strong>x<strong>1024</strong></td></tr></tbody></table>

## Quick Example

Let's generate an image of the specified size using a simple prompt.

{% tab title="Python" %}
{% code overflow="wrap" %}

```python
import requests
import json  # for getting a structured output with indentation

def main():
    response = requests.post(
        "https://api.aimlapi.com/v1/images/generations",
        headers={

            "aspect_ratio": '21:9'

    )

    data = response.json()
    print(json.dumps(data, indent=2, ensure_ascii=False))

if __name__ == "__main__":
    main()
```

{% endcode %}
{% endtab %}

```javascript

  const data = await response.json();
  console.log(data);
