A few months ago, I ran an experiment to create Telex<\/a> cover images using OpenAI and Google Nano Banana models. The goal was to generate images with a specific style using the same prompt across both models.<\/p>\n\n\n\n

Telex is an experimental AI tool for creating WordPress blocks through an interactive AI coding assistant in a visual, live-preview environment directly in the browser.<\/p>\n\n\n\n

The idea behind the experiment was to reproduce the dithering aesthetic of the Telex website for user-created projects. These cover images would be used as sharing images for blogs and social platforms, and potentially in the future dynamic project showcase on the Telex homepage.<\/p>\n\n\n\n

These are some of the images produced. All of them were created using the same prompt:<\/p>\n\n\n\n
