Model Overview

GPT Image 1 is OpenAI's new state-of-the-art image generation model. It's a natively multimodal language model that generates images based on a text prompt.

If you don’t have an API key for the AI/ML API yet, feel free to use our Quickstart guide.

API Schema

Note that by default, the quality parameter is set to 'medium'. The output image will still look great, but for even more detailed results, consider setting this parameter to 'high'.

Quick Example

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

Python

import requests
import json

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": "A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses. Realistic photo.",
            "model": "openai/gpt-image-1",
            "size": "1536x1024"
        }
    )

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

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


if __name__ == "__main__":
    main()

JS

async function main() {
  try {
    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({
        prompt: 'A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses. Realistic photo.',
        model: 'openai/gpt-image-1',
        size: '1536x1024'
      }),
    });

    if (!response.ok) {
      throw new Error(`HTTP error! Status: ${response.status}`);
    }

    const data = await response.json();
    console.log('Generation:', data);

  } catch (error) {
    console.error('Error:', error);
  }
}

main();

We obtained the following 1536x1024 image by running this code example (~ 26 s):

"A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses. Realistic photo."
