Side-by-side example with DALL-E 3
Generate an image of "a futuristic cityscape at sunset with flying cars" using the OpenAI Python SDK and DALL-E 3 model.
import os
from openai import OpenAI
client = OpenAI(api_key=os.environ["OPENAI_API_KEY"])
response = client.images.generate(
model="dall-e-3",
prompt="a futuristic cityscape at sunset with flying cars",
n=1,
size="1024x1024"
)
image_url = response.data[0].url
print(image_url)https://openai-generated-images.com/futuristic-cityscape-xyz123.png
