Hands-On: Generating Images with the DALL-E 3 API

This section guides you through generating images using the DALL-E 3 API.

Workflow:

Simplified DALL-E 3 API interaction workflow

The process involves a front-end (user prompt input) and a back-end (API interaction).

Setup:

You'll need Python, the OpenAI library (pip install --upgrade openai), and an OpenAI API key. Follow these steps to obtain your key:

Steps to obtain an OpenAI API key

Set your API key as an environment variable:

import os
OPENAI_API_KEY = "<your_api_key>"
os.environ["OPENAI_API_KEY"] = OPENAI_API_KEY</your_api_key>

Image Generation Code:

This Python code utilizes the OpenAI library:

from openai import OpenAI
from IPython.display import Image

client = OpenAI()

def get_image_from_DALL_E_3_API(user_prompt, image_dimension="1024x1024", image_quality="hd", model="dall-e-3", nb_final_image=1):
    response = client.images.generate(
        model=model,
        prompt=user_prompt,
        size=image_dimension,
        quality=image_quality,
        n=nb_final_image,
    )
    image_url = response.data[0].url
    display(Image(url=image_url))

#Example usage:
puppy_prompt = "Create an image of a cute brown puppy sitting in a green meadow under a clear blue sky."
get_image_from_DALL_E_3_API(puppy_prompt)
