What Seedream 4.5 is best at

Seedream's signature trick is saturation without mush: color laid on thick while edges stay crisp, where most models start smearing into watercolor. Proof sits at the top of this page — iridescent feathers, sharp pollen particles, deep blue-hour gradients, all from a single prompt through this route. That makes it the route to reach for on nature, food, product glamour and any artwork where color fidelity is the point.

The practical advantage here is comparison: run the same prompt across GPT Image 2, Gemini and Seedream routes and pick the strongest result — no app downloads, no separate accounts, one workspace.
