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

enhance_promptbooleanOptional

Optional parameter to use an LLM-based prompt rewriting feature for higher-quality images that better match the original prompt. Disabling it may affect image quality and prompt alignment.

Quick Example

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

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={
            "prompt": "Racoon eating ice-cream",
            "model": "google/imagen-4.0-generate-001",
            "aspect_ratio": "16:9"
        }
    )

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

if __name__ == "__main__":
    main()
Response
{
  "data": [
    {
      "mime_type": "image/png",
      "url": "https://cdn.aimlapi.com/generations/guepard/1758236160134-5fcac25f-0c87-4145-b24b-98ccebab5c0c.png",
      "prompt": "A mischievous racoon, with beady eyes and a striped tail, is caught mid-lick, enjoying a stolen ice cream cone. Its small paws cradle the melting treat, and its face is smeared with the creamy sweetness, indicating a thorough and enthusiastic indulgence. The scene is set in a cluttered alleyway, with discarded boxes and old bricks forming a backdrop to the racoon's illicit feast."
    }
  ],
  "meta": {
    "usage": {
      "tokens_used": 84000
    }
  }
}

So we obtained the following 1408x768 image by running this code example:

In reality, raccoons shouldn’t be given ice cream or chocolate—it’s harmful to their metabolism. But in the AI world, raccoons party like there’s no tomorrow.
