Photorealistic — Side-by-Side Results
Prompt
"Hyperrealistic DSLR-quality photo of a 20s woman with shoulder-length wavy dark brown hair and light freckles, wearing an oversized grey hoodie and black leggings, holding her phone slightly above eye level for a casual selfie while glancing near the lens with a half-smile. She’s in a small sunlit kitchen making iced coffee, one hand on a mason jar with condensation, cluttered counter with a cutting board and cereal box in the background; natural morning window light with realistic shadows and skin texture. Candid, slightly imperfect framing like an Instagram story, subtle motion blur in the stirring hand, no glam retouching."

Verdict
If your priority is photorealistic accuracy from a written brief—with fewer rounds to get the exact scene, lighting, and details—GPT-Image 1.5 is often the better first pick for text-to-image hyperrealism.
