Same prompt, every model

See the difference before you pay for it

One prompt, one image from each model, default settings. The prompt asks for a mug that says “ship it”.

How we tested

Prices

Every image model

Prices are per image at the default size. Models billed by tokens show a typical price; the real cost depends on size and quality and is returned with every response.
