# FLUX.2 Klein vs GPT Image 2

GPT Image 2 (at the ceiling) scores higher than FLUX.2 Klein (24) on the photo-anchored quality scale, where a real photograph is 100.

Both scores come from blind pairwise tests on the same 48 scenes between 21 and 25 August 2026: 288 pairs and 863 judgements, each pair judged 3 times.

## Scores

| Model | Score | 95% interval | Rank | Results |
|---|---|---|---|---|

| GPT Image 2 | 104.4 | fixed rung of the scale | #1 | https://workroom.everypixel.com/models/gpt-image-2 |

A real photograph is 100. A score above 100 is the scale's technical ceiling and does not mean parity.

## By use case
