GPT Image 1: OpenAI's Powerful Image Generation Model

OpenAI's GPT Image 1 (gpt-image-1) represents a significant leap forward in AI-powered image generation technology. This powerful model, which powers the image generation capabilities in ChatGPT, has now been made available to developers through OpenAI's API. Since its release, it has gained immense popularity, with OpenAI reporting that over 130 million users have created more than 700 million images during just the first week after launch.

This comprehensive guide will walk you through everything you need to know about GPT Image 1, from its capabilities and technical implementation to real-world applications and pricing details.

What is GPT Image 1?

GPT Image 1 is OpenAI's advanced multimodal AI model specifically designed for image generation and manipulation. It's the same technology that powers the image creation features in ChatGPT and has been responsible for viral trends like the Studio Ghibli-styled images that swept across social media. The model leverages deep learning techniques to understand and generate visual content based on text prompts or existing images.

Unlike previous image generation models, GPT Image 1 can not only create images from text descriptions but also edit existing images, perform inpainting (modifying specific areas of an image), and even combine multiple images based on textual instructions.

Let's explore some important features this model has.

Key Features and Capabilities

Text-to-Image Generation

GPT Image 1 excels at creating high-quality, detailed images from text descriptions. The model has been trained to understand complex prompts and generate corresponding visuals with impressive accuracy. Users can specify various aspects such as style, composition, lighting, and subject matter in their prompts.

from openai import OpenAI

client = OpenAI(api_key="YOUR_API_KEY")

response = client.images.generate(
    model="gpt-image-1",
    prompt="a photorealistic image of a futuristic cityscape at sunset, with flying vehicles and holographic billboards",
    n=1,  # Number of images to generate
    size="1024x1024"  # Desired image size
)

image_url = response.data[0].url
print(image_url)

Image Editing

One of GPT Image 1's standout features is its ability to edit existing images based on text instructions. This allows for seamless modifications without requiring specialized graphic design skills.

from openai import OpenAI

client = OpenAI(api_key="YOUR_API_KEY")

response = client.images.edit(
    model="gpt-image-1",
    image=open("original_image.jpg", "rb"),
    prompt="change the background to a tropical beach",
    n=1,
    size="1024x1024"
)

image_url = response.data[0].url
print(image_url)

Inpainting: Precision Editing

Inpainting is a powerful feature that allows users to modify specific portions of an image by creating a mask over the area to be changed and providing a text description of the desired modification. This capability enables highly precise edits that blend seamlessly with the rest of the image.

What makes this more interesting is, this feature is only available through the API and not via ChatGPT. Honestly, this comes super handy and you can get a lot creative with this one!

from openai import OpenAI
from PIL import Image
import numpy as np
import io
import base64

client = OpenAI(api_key="YOUR_API_KEY")

# Load the original image
original_image = Image.open("portrait.jpg")

# Create a mask (white pixels indicate areas to modify)
mask = Image.new("RGB", original_image.size, (0, 0, 0))
# Here you would programmatically create your mask
# For example, drawing a white rectangle over the area to modify
# For this example, we'll create a simple mask

# Convert images to base64 strings
def image_to_base64(img):
    buffer = io.BytesIO()
    img.save(buffer, format="PNG")
    return base64.b64encode(buffer.getvalue()).decode('utf-8')

original_base64 = image_to_base64(original_image)
mask_base64 = image_to_base64(mask)

response = client.images.edit(
    model="gpt-image-1",
    image=original_base64,
    mask=mask_base64,
    prompt="remove the necklace and replace with a simple gold chain",
    n=1,
    size="1024x1024"
)

image_url = response.data[0].url
print(image_url)

Image Combination

GPT Image 1 can combine multiple images based on a text prompt, effectively creating a cohesive composition that integrates elements from various sources.

So you can literally put 4 different things and different images altogether into one single one!

from openai import OpenAI

client = OpenAI(api_key="YOUR_API_KEY")

response = client.images.generate(
    model="gpt-image-1",
    prompt="create a seamless collage of these images showing a cohesive landscape",
    n=1,
    size="1024x1024",
    image=["path/to/image1.jpg", "path/to/image2.jpg", "path/to/image3.jpg"]
)

image_url = response.data[0].url
print(image_url)

Identity Verification Requirement

A crucial aspect of accessing GPT Image 1 is the mandatory identity verification process:

1. Government-Issued ID: OpenAI requires users to verify their identity by submitting a government-issued ID before gaining access to the GPT Image 1 model.

2. Processing Timeline: According to user experiences, this verification process typically takes approximately 30 minutes to complete, although this can vary.

3. Purpose of Verification: This verification step helps OpenAI ensure responsible use of their powerful image generation technology and maintain compliance with regulatory requirements.

4. One-Time Process: Once verified, users don't need to repeat the verification for subsequent uses of the API.

The verification process typically involves:

• Logging into your OpenAI account

• Navigating to the verification section

• Uploading clear images of your government-issued ID

• Waiting for approval (approximately 30 minutes)

The reason for verification quoted by OpenAI is to ensure this model is used responsibly. And I think that is fair.

Now let's move on to some technical implementation.
