Run a complete example

This runnable example remains pinned to gpt-image-2. Use it as a baseline, then choose an available model and its supported request settings for your evaluation.

The examples below generate four logo variations and extract a product onto a transparent background. Install the OpenAI SDK with pip install openai for Python or gem install openai for Ruby. Set OPENAI_API_KEY and save the product photograph as input_images/shampoo.webp. Live requests incur API usage charges.

Create an original, non-infringing logo for a company called Field & Flour, a local bakery.
The logo should feel warm, simple, and timeless. Use clean, vector-like shapes, a strong silhouette, and balanced negative space.
Favor simplicity over detail so it reads clearly at small and large sizes. Flat design, minimal strokes, no gradients unless essential.
Fully transparent background. Deliver a single centered logo with generous padding, clean alpha edges, and no solid backdrop, scenery, checkerboard, or watermark.
