I compared ChatGPT and Gemini — a single prompt tweak made a big difference

Contributor Lance Whitney recommends letting a chatbot craft the full image prompt from a short description. His example: request "a sunflower made of sheet metal in a pencil drawing style," then ask the AI to generate a complete prompt for [Nano Banana or ChatGPT Images].

That approach supplies basic details and lets the bot expand them into a more precise query. The writer tested Gemini and ChatGPT with their respective image generators, Nano Banana and ChatGPT Images. Gemini returned a prompt describing a pencil drawing of a metal sunflower, with petals, leaves and stem composed of sculpted metal sheet, visible imperfections and welds, detailed shading to emphasize three-dimensional form, and pencil lines with a garden and blurry plants in the background.
