Average weighted score across 91 realistic-style prompts. All 18 models completed all prompts (GPT Image 1.5 completed 91/91).
What Makes Photorealism Hard
Photorealism simultaneously stresses every scoring dimension — visual fidelity, physics & logic, subject integrity, and instruction adherence. A single anatomical error or lighting inconsistency breaks the illusion entirely.
Where top models excel
- Skin texture detail (pores, subsurface scattering, natural sheen)
- Lighting physics (caustics, rim light, ambient occlusion)
- Anatomical accuracy (hands, ears, joints, eye symmetry)
- Material properties (fabric weave, metal reflections, glass refraction)
Where models still struggle
- Complex hand poses with all 10 fingers visible
- Teeth and dental detail at close range
- Individual hair strands at macro level
- Transparent materials with caustic light interactions
Portrait & Human Photography
GPT Image 1.5 leads portrait prompts by a wider margin than its overall photorealism advantage[2]. The key differentiator is facial anatomy — eye symmetry, ear structure, natural expressions, and realistic skin rendering under varied lighting conditions.
Seedream 4.5 (rank 6 overall)[8] has notable anatomical failures on certain portrait prompts — split faces, body clipping, and unnatural joint articulation — that drag down its photorealism average despite strong performance on non-human subjects.

The Value Equation
Best model per pricing tier — showing the top option at each price point for photorealistic generation.
| Model | Score | Cost | 100 Images |
|---|---|---|---|
| GPT Image 1.5 | 4.668 | $0.133 | $13.30 |
| FLUX.2 Pro | 4.555 | $0.035 | $3.50 |
| Qwen Image 2512 | 4.337 | $0.003 | $0.30 |
FLUX.2 Pro delivers 97.6% of GPT's photorealism at 26% of the price. For teams generating photorealistic images at scale, that's a 3.8x cost reduction with a barely perceptible quality difference. Qwen at $0.003[9] covers social media and prototyping use cases at 93% of top-tier quality.

The Verdict
For professional editorial & commercial
GPT Image 1.5 or Nano Banana Pro — both score above 4.66, with GPT having the edge on portraits and NBP slightly stronger on environmental scenes. The gap is essentially zero; choose based on your subject.
For general photorealism
FLUX.2 Pro at $0.035 delivers 97.6% of premium quality. The gap vs GPT is 0.11 points — imperceptible in most outputs. 3.8x cheaper than the premium tier with no content restrictions.
For budget photorealism
Seedream 3.0 at $0.018[7] for the best budget-to-quality ratio, or Qwen Image 2512 at $0.003 for high-volume generation at 93% of top-tier quality. Both handle social media and prototyping well.

FAQ
Which AI makes the most realistic images?
GPT Image 1.5 (4.67) on our photorealism benchmark, followed by Nano Banana Pro (4.67). Both excel at skin texture, lighting physics, and anatomical accuracy. FLUX.2 Pro (4.56) is nearly as good at 1/4 the price.
Can AI generate realistic portraits?
Yes — top models score above 4.5/5 on portrait prompts. GPT Image 1.5 leads for facial anatomy and expression accuracy. The main remaining challenge is hand/finger accuracy on complex poses.
What makes photorealism hard for AI?
Fine anatomical detail (hands, ears, teeth), physically accurate lighting (caustics, subsurface scattering), and material properties (skin pores, fabric weave, metal reflections). These stress-test physics, subject integrity, and visual fidelity simultaneously.
