## Model Overview

`flux-pro/v1.1` is a new image generation model with inference speed increased sixfold compared to the previous `flux-pro`. It also features enhanced generation quality and greater accuracy in following prompts.

## Quick Example

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

{% hint style="warning" %}
The maximum value for both width and height is `1440`, and the minimum is `256`.\
The value must be a multiple of 32.
{% endhint %}
