Body

modelundefined · enumRequiredPossible values:

image_sizeany ofOptionalDefault: landscape_4_3

or

string · enumOptional

The size of the generated image.

Possible values:

num_inference_stepsinteger · min: 1 · max: 50Optional

The number of inference steps to perform.

Default: 28

guidance_scalenumber · min: 1 · max: 20Optional

The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt when looking for a related image to show you.

Default: 4.5

sync_modebooleanOptional

If set to true, the function will wait for the image to be generated and uploaded before returning the response. This will increase the latency of the function but it allows you to get the image directly in the response without going through the CDN.

Default: false

enable_safety_checkerbooleanOptional

If set to True, the safety checker will be enabled.

Default: true

output_formatstring · enumOptional

The format of the generated image.

Default: jpegPossible values:

accelerationstring · enumOptional

The speed of the generation. The higher the speed, the faster the generation.

Default: regularPossible values:

promptstring · max: 4000Required

The text prompt describing the content, style, or composition of the image to be generated.

num_imagesnumber · min: 1 · max: 4Optional

The number of images to generate.

Default: 1

seedinteger · min: 1Optional

The same seed and the same prompt given to the same version of the model will output the same image every time.

Quick Example

Let's generate an image using a simple prompt.

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={
            # Insert your AIML API Key instead of <YOUR_AIMLAPI_KEY>:
            "Authorization": "Bearer <YOUR_AIMLAPI_KEY>",
            "Content-Type": "application/json",
        },
        json={
            "model": "flux/srpo",
            "prompt": "A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses.",
            "image_size": {
                "width": 1440,
                "height": 512
            }  
        }
    )

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

if __name__ == "__main__":
    main()

JS

async function main() {
  const response = await fetch('https://api.aimlapi.com/v1/images/generations', {
    method: 'POST',
    headers: {
      // Insert your AIML API Key instead of <YOUR_AIMLAPI_KEY>:
      'Authorization': 'Bearer <YOUR_AIMLAPI_KEY>',
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      model: 'flux/srpo',
      prompt: 'A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses.',
      image_size: {
                width: 1440,
                height: 512
            }
    }),
  });

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

main();
