Install the OpenAI Python SDK

First, install the official OpenAI Python package:
You can also pin a specific version for reproducibility:

Initialize the OpenAI Client

Import and initialize the client using your API key. We recommend storing your key in an environment variable for security.
Never hard-code your API key in source files. Use environment variables or a secrets manager.

Define a Helper Function

Create a reusable function that sends a prompt to DALL·E 3 and returns the URL of the generated image:

Generate Your First Image

Use the helper function in a standalone script:
Run it:
Open the printed URL in your browser to see your AI-generated artwork.

Experiment with Custom Prompts

Change the prompt text to explore different styles and concepts:
Feel free to iterate on your prompt until you find the perfect visual.
