GPT Image 1.5 vs GPT Image 2: Which One Should You Use

The site has 24 and 429 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; GPT Image 2 is better for Conversational, iterative editing. 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.

GPT Image 2

Conversational, iterative editingUnderstanding of natural-language descriptionsPhoto stylization & local replacementChinese prompts work directly

It responds better to conversational descriptions than to stacks of parameter keywords. When editing an image, saying "change the background to…" is more efficient than rewriting the whole prompt.
