Artificial Intelligence is changing the way we create images, graphics, and visual content. For many beginners, high-end AI models are too expensive or too heavy for basic projects.
To solve this, OpenAI introduced a lightweight and affordable model called OpenAI GPT Image 1 Mini.
This blog explains everything about this model in simple Language — what it is, how it works, pricing, use cases, and Python code samples using the GPT Image-1-Mini API.
What Is OpenAI GPT Image 1 Mini?
OpenAI GPT Image 1 Mini is a small, cost-effective image generation model created for:
- Students
- Freshers
- Junior developers
- Startups
- Hackathon participants
- Low-budget AI projects
It takes a text prompt and returns an AI-generated image, similar to DALL·E, but at a cheaper and faster level.
Why the “Mini” Version?
- Low cost
- Fast response
- Good quality for simple images
- Easy to integrate
- Great for small projects and experiments
It focuses on being affordable + fast, not ultra-realistic like bigger models.
How OpenAI GPT Image 1 Mini Works
It follows a simple pipeline:
- You give a text prompt
- The model understands your description
- It generates an image matching the prompt
- API returns:
- A public image URL, or
- Base64 image data
It supports popular image sizes like 256×256, 512×512, and 1024×1024.
GPT Image-1-Mini API Overview
The GPT Image-1-Mini API is the HTTP API that lets you generate images programmatically.
The API request includes:
- model:
"gpt-image-1-mini" - prompt: Your text description
- size: For example,
"1024x1024" - n: Number of images
The API responds with image URLs.
GPT Image 1 Mini Example (Simple Prompt)
Here’s a simple example prompt:
“Generate a cartoon-style illustration of a student coding on a laptop in a college library, colorful and friendly design.”
This is perfect for:
- College mini-projects
- Posters
- App UI design
- Thumbnails
Python Code Example for GPT Image 1 Mini
Below is a complete and working Python code using the GPT Image-1-Mini API.
Python Code (Official OpenAI API Usage)
from openai import OpenAI
import base64
import requests
client = OpenAI(api_key="YOUR_API_KEY")
# Step 1: Generate image from prompt
response = client.images.generate(
model="gpt-image-1-mini",
prompt="Create a colorful cartoon illustration of a college student coding on a laptop in a library",
size="1024x1024",
n=1
)
# Step 2: Extract the image URL
image_url = response.data[0].url
print("Image URL:", image_url)
# Step 3: Download the image locally (optional)
image_data = requests.get(image_url).content
with open("student_coding.png", "wb") as f:
f.write(image_data)
print("Image saved as student_coding.png")
What the code does:
| Step | Meaning |
|---|---|
| 1 | Sends prompt to GPT Image 1 Mini |
| 2 | Receives generated image link |
| 3 | Downloads and saves the image locally |
This script is perfect for:
- Academic projects
- Student portfolio websites
- AI image generator apps
- Automation tools
More Python Examples (Flask API) – Using GPT Image-1-Mini API
If you want to use OpenAI GPT Image 1 Mini inside a web application, the easiest way is by using Flask.
This helps students and developers build their own AI Image Generator Web App.
Here is a fully working Flask API example.
Flask API Example – Generate Images Using GPT Image-1-Mini
Install Requirements
pip install flask openai requests
Flask App Code (app.py)
from flask import Flask, request, jsonify
from openai import OpenAI
import requests
import os
app = Flask(__name__)
client = OpenAI(api_key="YOUR_API_KEY")
@app.route("/generate-image", methods=["POST"])
def generate_image():
try:
data = request.json
prompt = data.get("prompt", "")
if not prompt:
return jsonify({"error": "Prompt is required"}), 400
# Call GPT Image-1-Mini API
response = client.images.generate(
model="gpt-image-1-mini",
prompt=prompt,
size="1024x1024",
n=1
)
image_url = response.data[0].url
# Optional: Download image & save locally
img_data = requests.get(image_url).content
file_name = "generated_image.png"
with open(file_name, "wb") as f:
f.write(img_data)
return jsonify({
"status": "success",
"image_url": image_url,
"saved_as": file_name
})
except Exception as e:
return jsonify({"error": str(e)}), 500
if __name__ == "__main__":
app.run(debug=True)
How to Use the API
Send a POST request:
{
"prompt": "create a cartoon robot teaching coding"
}
Use Postman, Thunder Client, or your frontend.
Output Example
{
"status": "success",
"image_url": "https://openai-generated-image-url.com/xyz",
"saved_as": "generated_image.png"
}
This lets you build:
- AI image generator apps
- Hackathon projects
- College mini-projects
- Image automation tools

client = OpenAI(api_key="YOUR_API_KEY")
response = client.images.generate(
model="gpt-image-1-mini",
prompt="Make a cute cartoon of a robot teaching coding to kids",
size="512x512",
response_format="b64_json"
)
# Extract base64 data
image_base64 = response.data[0].b64_json
# Decode and save
image_bytes = base64.b64decode(image_base64)
with open("robot_teacher.png", "wb") as f:
f.write(image_bytes)
print("Image saved as robot_teacher.png")
