Recipe
The examples above were generated with Nano Banana Pro and Seedream 4.5. The recipes below are written for GPT Image and Flux, so treat the settings as a starting point rather than the exact run.
A description in plain sentences. This is the version to start with, and it works on any current image model. Settings below are the ones we used on GPT Image; treat them as a starting point.
This recipe describes a treatment rather than a thing. Put your own subject in and it is added to the end of the prompt.
Industrial concept art halfway between a drawing and a render: the machine painted in clean flat colour with soft shading, and loose construction lines, section marks and cable routing drawn over the top in thin ink. Plain grey background with a few stray guide lines running off the edge of the sheet. Confident designer's hand, no lettering or annotation text anywhere. Subject: a small racing kart with exposed cables.
