How to spot ByteDance Seedream AI images

Seedream produces strikingly photorealistic portraits and scenes, but its decoder still leaves the characteristic fingerprints of a diffusion model:

01

Over-Smoothed Skin With Missing Pores

Seedream faces look airbrushed — skin is rendered smooth and even, lacking the pores, fine wrinkles, and asymmetric blemishes of real photography.

02

Uniform Catchlights in the Eyes

Both eyes reflect identical, symmetric catchlights that fail to match the actual lighting or environment, a telltale sign of synthetic generation.

03

Background Geometry Warping

Straight lines in architecture, furniture, and tiling bend or drift near the subject, and repeating patterns melt together on close inspection.

04

Plastic Specular Highlights

Highlights on skin, lips, and surfaces read as glossy and plastic, sitting on top of the image rather than integrating with its material and light.

How the verification engine works

1. Ingest Media
Upload a video clip, full-resolution photo, or paste any direct media link.
2. Multi-Layer Scan
Scans for frequency patterns, flow-matching artifacts, and generative diffusion noise.
3. Instant Verdict
Clear Real vs. AI verdict with confidence scores, detected generator model, and reverse matches.
