For photorealistic work in Influencer Studio—skin texture, natural lighting, believable materials, and camera-like depth—both GPT-Image 1.5 and Seedream 4.5 can deliver hyperrealistic results that read like real photos when prompted well. The difference is less about “can they do realism?” and more about how consistently they hit a true-to-brief photographic look and what controls you get along the way.
GPT-Image 1.5 leans into prompt adherence and high-fidelity scene detail, making it a strong choice when you need a precise, photo-accurate outcome from text alone. Seedream 4.5 stands out for editing and iteration, helping you refine photorealistic outputs through image-to-image workflows while still maintaining high-resolution clarity.
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. It’s also easier to scale cost up or down depending on whether you’re drafting concepts or producing a hero frame.
If your workflow depends on editing and controlled iteration—especially when you already have a base image and want to refine realism without restarting—Seedream 4.5 is the stronger choice for photorealistic pipelines that require consistent tweaks and revisions.
