GPT Image 1.5 vs Grok Imagine: Which One Should You Use

The site has 31 and 5 reproducible cases for each, respectively. Below, we compare strengths, prompt writing, and final results side by side.

The Bottom Line

GPT Image 1.5 is better for Preserving faces and logos through edits; Grok Imagine is better for Fast visualization of a concept. Running the same idea through both is usually worth it — they "listen" differently, so the prompt has to be adjusted to match.

Strengths & Prompt-Writing Comparison

GPT Image 1.5

Preserving faces and logos through editsRendering dense in-image textPhotographic texture and material feelFollowing long, paragraph-length instructions
It responds to a complete scene description: state the frame, camera position, lighting and materials in separate sentences instead of piling on style words. When editing, say explicitly "change only X, leave everything else as is" — that is where its preservation strength shows.

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.
