GPT Image 1 vs GPT Image 1.5: Which One Should You Use

The site has 52 and 24 reproducible cases for each, respectively. Below, we compare strengths, prompt writing, and final results side by side.

The Bottom Line

GPT Image 1 is better for Paragraph-length natural-language scene descriptions; GPT Image 1.5 is better for Preserving faces and logos through edits. 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

Paragraph-length natural-language scene descriptionsShort in-image titles and signage textPhotographic portraits and sports actionIllustration and flat stylization
Write in the order frame – subject – camera position – lighting – materials – mood, one sentence each; that is steadier than stacking style words. Negative instructions are not reliably followed, so phrase exclusions positively — write "a clean solid-color background" rather than "no clutter".

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.
