The site has 287 and 5 reproducible cases for each, respectively. Below, we compare strengths, prompt writing, and final results side by side.

Strengths & Prompt-Writing Comparison

GPT Image 2.5

Executing long paragraph-length scene descriptionsFine gradation in materials and lightingStable letterforms for in-image text and layoutProduct and still-life texture fidelity

Split the frame into four blocks - subject, environment, light, camera - and write each separately; that works far better than piling on style words. It is also more reliable than the previous version at local edits phrased as "change only this one thing, leave the rest alone".

Grok Imagine

Fast visualization of a conceptStylized and exaggerated treatmentsHigh-contrast, social-ready framesWorks even from short prompts

Keep the prompt short and put the one counter-intuitive combination you actually want at the very front. Add camera and lighting detail afterwards, one or two at a time — pile them on and it loses the point.
