Bytedance | Seedream | v4.5 | Edit

Seedream 4.5 Edit delivers high‑fidelity, prompt‑driven image edits while preserving subject identity, lighting, color balance, and fine material detail. Built on a unified generation/editing architecture, it handles single images and multi‑image batches with strong cross‑image consistency—ideal for portraits, products, and branded visuals. You can precisely recolor products, apply cinematic grades, replace backgrounds, and add dense, legible typography, all while keeping composition intact. For best results, structure prompts with “preserve” then “change” instructions, iterate at 1–2K previews, and finalize near 4K for sharp details and clean text. It enables retoucher‑level control, consistent series outputs, and professional production quality.
