GPT Image Prompt Lab

Write gpt-image prompts that actually work. Describe a picture in one sentence and the lab matches it against 22 industrial gpt-image templates reverse-engineered from 541 real results, writes the full six-block prompt - subject, composition, style, text, aspect ratio, constraints - and checks it in your browser before you spend anything. Attach a reference picture and the writer describes it into the prompt for you; the renderer only ever reads words. Edit every word, then render with gpt-image. Templates and corpus from the awesome-gpt-image-2 skill by freestylefly (MIT).
