flux-pro

This documentation is valid for the following list of our models:

• flux-pro

• flux-pro/v1.1

Model Overview

Both versions, v.1 and v1.1, generate images of unmatched quality, outperforming popular models like Midjourney v6.0, DALL·E 3 (HD), and SD3-Ultra.

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.

Both versions accept the same set of parameters, generate JPEGs, and have identical minimum, maximum, and default image sizes.

Model	Properties of Generated Images
flux-pro	Format: JPG Min size: 256x256 Max size: 1440x1440 Default size: 1024x768 For both height and width, the value must be a multiple of 32.
flux-pro/v1.1	Format: JPG Min size: 256x256 Max size: 1440x1440 Default size: 1024x768 For both height and width, the value must be a multiple of 32.

Quick Example

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

The maximum value for both width and height is 1440, and the minimum is 256. The value must be a multiple of 32.

import requests


def main():
    response = requests.post(
        "https://api.aimlapi.com/v1/images/generations",
        headers={
            # Insert your AIML API Key instead of <YOUR_AIMLAPI_KEY>:
            "Authorization": "Bearer <YOUR_AIMLAPI_KEY>",
            "Content-Type": "application/json",
        },
        json={
            "prompt": "Rabbit singing",
            "model": "flux-pro",
            'image_size': {
                "width": 1024,
                "height": 320
            }
        }
    )

    response.raise_for_status()
    data = response.json()

    print("Generation:", data)


if __name__ == "__main__":
    main()

Response
